DETAILED DESCRIPTION

(17) In the following descriptions, the present invention will be explained with reference to various example embodiments; nevertheless, these embodiments are not intended to limit the present invention to any specific example, environment, application, or particular implementation described herein. Therefore, descriptions of these example embodiments are only provided for purpose of illustration rather than to limit the present invention. Conventional operating logic for transportable satellite antenna devices is known to those having skill in the art, and therefore, will not be repeated herein.

(18) The antenna apparatus can be configured as an manually or hand transportable antenna system (with or without handle) such as that disclosed in U.S. Pat. No. 7,595,764, the entirety of which is hereby incorporated by reference herein. Indeed, portions of the following description refer to the VUQUBE (VQ) hand portable motorized and enclosed satellite TV antenna product. This product is available from King Controls at www.kingcontrols.com. However the present invention can also be adapted to any manner of satellite television antenna products and configurations. For example it can be adapted to a vehicular mobilized satellite antenna product for mounting on the roof of a vehicle such as the KING DOME antenna product, also available from King Controls. Additionally, the disclosure of U.S. Pat. Nos. 6,864,846 and 6,937,199, and the disclosure of U.S. application Ser. No. 12/845,488, filed on Jul. 29, 2010, are all hereby incorporated by reference herein in their entirety as these references show additional satellite antenna device examples that can be adapted to certain embodiments of the current invention.

(19) The operations, structural devices, acts, modules, logic and method steps discussed herein below, according to certain embodiments of the present invention, may take the form of a computer program or software code stored on a tangible or non-transitive machine-readable medium (or memory) in communication with a processor which executes the code to perform the described behavior, function, features and methods. It will be recognized by one skilled in the art that these operations, structural devices, acts, logic, method steps and modules may be implemented in software, in firmware, in special purpose digital logic, and any combination thereof without deviating from the spirit and scope of the present invention as recited within the claims attached hereto.

(20) General satellite antenna system operation and interaction with the STB according to one example embodiment is depicted in the flowchart of FIGS. 1A and 1B, which pertains generally to the following descriptions of certain operational states. Detailed discussion of certain aspects will be discussed with regard to FIGS. 2-11.

(21) Referring then to FIGS. 1A and 1B, the STB queries through the communicating line attached to the antenna to determine the identity of the antenna that is connected 100. The responses can include a determination that there is no antenna connected, that a home or fixed antenna is connected or that a mobile/portable antenna is connected. If a mobile/portable is connected, then an antenna firmware update check can be performed and the firmware updated, if necessary 102.

(22) Next, a setup or startup screen is presented to the user on the television connected to the STB 104. The setup screen can, but need not, request certain information from the user such as geographic location.

(23) Then an exchange of data occurs between the STB and antenna, including data relayed from scans 106 by the antenna in response to status queries by the STB 108. This exchange includes the STB providing the antenna with the network identifications (NIDs or IDs) of each satellite candidate 110 that the antenna locks onto. This process continues until all of the desired satellites are found (so the user can watch the full set of TV channels 112), or until no further satellite candidates can be identified by the antenna. This latter condition may be the result of some, but not all, of the desired satellites being found 114, or may be the result of an inability to find any of the desired satellites 116. The user setup screen may be updated with status messages during the satellite acquisition process 118.

(24) If satellite signal is lost as noticed by the STB, it sends an antenna check query 120 through the communication line to the antenna. If no recognized hardware is found, the user can be prompted to check the antenna connection, or some other suitable error warning. The STB can continue to check for an antenna connection until one is found. Once a viable antenna is located, the process can start again, or the previous status can be resumed if a predefined timeout period has not expired.

(25) Certain aspects of the system operation, function and features will now be described with respect to FIGS. 2-11. Referring in particular to FIG. 2, the logic of normal power up routine for a STB is shown in greater detail. A coaxial cable can be used to connect the STB to the antenna system to provide a means for communication or communication line therebetween. This single cable can also be the same cable through which satellite broadcast signals received by antenna are transmitted to the STB. Thus, the communication line connecting the antenna to STB can be a two-way communication conduit. Other communications means such as wireless (e.g., Wi-Fi, Bluetooth, radio, infrared, cellular, etc.) may also be used. Signals can also be exchanged over multiple communications conduits and means. Power to the antenna can also be supplied by the STB to the motorized antenna device by the same single cable line through which the two-way communications are occurring. Thus, cables, cost and setup complexity are minimized. Reliability and quality are also improved.

(26) After the STB is powered up 120, the STB queries for antenna identification 122. The STB thus can determine whether a home/fixed antenna is connected 124, whether a motorized mobile/portable antenna is connected 126 or whether no antenna is connected 128. The STB can be configured to default to home/fixed antenna operation if no antenna is connected. But if a motorized mobile/portable antenna is connected, then the ID of such antenna is obtained 130. A set-up page or status page can also be displayed on the user's television screen 132.

(27) The portable antenna system is placed by the user in a location with an unobstructed view of the relevant hemisphere of the sky (e.g. southern in the United States and Europe, northern in Australia and South America). The vehicle to which a mobile unit is attached would be moved, if necessary, to satisfy the same criteria. The STB is plugged into a power source, which also powers on the antenna system via the communication line or conduit. Alternatively, the antenna system can be provided with a separate direct or remote power switch. After powering up, the STB initiates an antenna identification and/or authentication query over the DiSEqC bus. The motorized mobile/portable antenna system is configured to respond with suitable identification or authentication information. This identification step can be performed, for example, automatically at power up, after the user presses a reset on the STB, or as initiated by the user via the STB user on-screen set up options interface.

(28) Referring now to FIG. 3, once the STB recognizes the mobile/portable antenna system, the STB displays the presence of the specific antenna system on the TV set up screen 134. The STB may also display the hardware and firmware version number, and the antenna configuration information. The user may be queried via prompts presented on the screen such as that shown in FIG. 4, to enter geographic information 136, such as a state, zip code or other location identifier. The STB in certain embodiments can use this geographic data and the user's subscription information (e.g., Dish 1000) to determine the set of satellites to be acquired by the antenna 138. Thereafter the STB automatically transmits to the antenna over the communications line the set or group of satellite IDs that are to be located and identified to watch TV 140. This is also referred to as the set or group of desired satellites. Each member of this group is referred to as a desired satellite. The antenna stores the set of desired satellite IDs (NIDs) in memory so they can be accessed during the satellite acquisition process.

(29) Referring to FIG. 5, it is again shown that the STB contains code to determine the set of desired satellites 138, the IDs of which are sent to and stored by the antenna 140. Prior to full scan, the antenna system sends a busy flag message to the STB 142 to indicate that scanning mode has been initiated. This causes the STB to update the LNB voltage and prepares for querying antenna system status 144. The status can be queried every 500 milliseconds for example, or some other acceptable value given the hardware employed. The LNB voltage is held at the requested level while the busy/scanning flag is set in response to status queries. A stable LNB voltage helps the antenna system to normalize the measurement of the microwave energy of any detected satellites. The invention can also be practiced without the setting of the LNB voltage steps depending on the type of LNB used in the antenna.

(30) The antenna system resets the motor drive 146 and starts a sky scan routine. The antenna first rotates its reflector dish via an azimuth motor to monitor background microwave signal (MW level) in order to set a signal-to-noise ratio 148. Then a scan is performed 150. During the scan, one or both of the azimuth and elevation motors of the antenna are actuated to move the dish in order to locate microwave (MW) hotspots 150. These hotspots are the satellite location candidates that will be further evaluated as discussed below.

(31) The antenna can also calculate a target elevation angle range based upon geographic location information provided by the STB. This calculation enables the antenna to begin its scan at a specified elevation or range of elevations in order to potentially reduce the search time needed to find satellite candidates. Another alternative to receiving location information from the STB is to provide the antenna with an onboard GPS receiver so that the antenna can use GPS data to determine appropriate elevation angle for its current location and quickly find satellite candidates.

(32) The GPS data from the antenna (or from STB internal GPS if so equipped) can also be used by the STB to enable or disable local programming corresponding to the location of the antenna and STB. For example, the STB can use location information to determine that it is not located in the user's home location, so programming corresponding to that home location can be disabled. In another example, the STB can enable local programming corresponding to the current location of the user so that the user can access and view programming that is designated as local to the user's current location.

(33) If the STB is unable to maintain the requested LNB voltage when in mobile/portable antenna system-STB mode, the antenna system can include additional hardware that would accept a range of voltages from the STB and follow the STB DiSEqC commands to control the LNB polarization by controlling LNB voltage locally. For this alternative, the overall control sequence would remain very similar to that described above, and will therefore, not be repeated herein.

(34) Referring now to FIG. 6 the scanning process will now be described in greater detail. After initiation of a sky scan 150, the antenna scans the sky in a predetermined pattern until it finds a MW signal that it identifies as a satellite candidate. One way this can be done is to look for MW energy hotspots that stand out against the background MW level. It can also be done other ways without departing from the scope of the invention. While the scan process is proceeding, the STB repeatedly queries the antenna for status (e.g. every 500 ms) 156. Once a candidate is found, the antenna locks onto and peaks or maximizes the lock for that candidate 152. The scan is stopped 154 and a locked flag is sent to the STB 158. The STB receives the locked flag 160 and decodes the NID of the satellite candidate from the candidate satellite's broadcast data stream being passed to the STB from the antenna over the communication line. The STB then passes the NID, if available, for the candidate satellite back to the antenna 162 in the next status exchange. NID is the network ID information contained within the satellite television data feed being broadcast from every such satellite.

(35) The antenna control system in the antenna apparatus then compares the NID of the satellite candidate as provided by the STB to the list of NIDs for the set of desired satellites 164. The antenna control system acts appropriately on the candidate NID to determine whether it has detected a member of the desired set and then continues the scan to try to detect any remaining members of the set of required (desired) satellites.

(36) FIG. 7 further illustrates the process by which the antenna system interacts with the STB to determine whether a given satellite candidate is a member of the set of desired satellites and whether all member desired satellites have been found. The antenna control system receives a candidate NID from the STB and compares that candidate's NID to the set of desired NIDs as previously provided by the STB 164. If a particular satellite candidate is either (1) unidentifiable or (2) identified, but not among the list of satellites needed (desired), the antenna clears the lock flag, sets a busy flag 166 and resumes the scan process 168. This process repeats until a satellite is identified that is among the set of desired satellites. If a desired satellite is found, then the antenna sends a satellite found message to the STB 170. The STB may also then update the status on the user's set up page 172.

(37) The antenna control system also stores in memory the orientation information for its reflector dish (e.g., elevation angle and azimuth) for a given satellite that is determined to be a member of the set of desired satellites. This allows the antenna to quickly move (or switch or jump) from a current desired satellite location to another desired satellite location when it receives a switch command from the STB. The satellite antenna control system can also store the dish orientation information corresponding to satellite candidates that it determines to not be among the set of desired satellites. By storing this latter orientation data, the antenna system can avoid locking onto the same non-desired candidate again.

(38) The antenna control system also decides if any additional desired satellites still need to be found 174. If yes, then the antenna clears the lock flag, sets a busy flag 176 and resumes scanning 168. This scan and evaluation process described above repeats until all desired satellites in the set are found or until the antenna cannot identify any more satellite candidates. As desired satellites are found, status can be updated on the viewer's set up page 172.

(39) When the antenna system has finished scanning (either by finding all required satellites, by finding no satellite candidates or finding some of the desired satellites after evaluating all possible candidates), it responds to a status query by the STB with a Scan Complete message. This message also carries a code for one of the following modes of completion: all required satellites found; some required satellites found; or no required satellites found. Based on the outcome, the user may start watching TV (in the first two options) or re-start a scan procedure after trying to resolve the potential issues causing a scan failure (in the last two options).

(40) Once the STB recognizes the scan process to be completed, the status query requests are no longer sent to the antenna system. The STB then returns to its normal operation of providing satellite television. After the sky scan is complete, the antenna system is directed to point at specific satellites via DiSEqC commands from the STB to the antenna control system. The antenna control system actuates one or more motors in response to these commands to aim or orient the antenna according to the stored dish orientation positions for the set of desired satellites.

(41) FIG. 8 shows certain aspects of the antenna system operation. The scan operation 180 is performed until a desired satellite is found 182. The setup page can be updated 184. And the antenna system compares the NIDs of the desired satellites it has found to the set of needed satellite NIDs previously provided by the STB 186. If all needed satellites were found, then an appropriate message to the STB causes the STB to stop sending queries to the antenna 188. But if not all of the desired satellites have been found, the scanning process is continued 180 in an effort to find additional desired satellite(s).

(42) FIG. 9 shows the process to accomplish a satellite switching or jumping operation. The user would be watching television on a first channel 190. That first channel corresponds to a particular satellite slot (first slot or position) where the satellite broadcasting that channel is located. If the user changes to a second channel 192 that happens to be broadcast from a satellite at a different location or slot (second position or slot), then the antenna system must re-orient its dish to receive data from that second slot. Thus, when a user changes channels, the STB determines whether the satellite corresponding to the new channel is located on a different satellite slot 194. If no, then the STB does not issue any commands to the antenna. But if yes, then the STB sends a switch command to the antenna control 196. The information or command to the antenna can either be to simply switch (if a two-satellite position set) or the satellite ID of the slot to switch to is provided. In response, the antenna control system energizes one or more motors to move the dish to the orientation corresponding to the target satellite position 198, which was already stored in the antenna's memory.

(43) Alternatively, the decision to switch can be made by the antenna using code executing on the antenna's processor. In such alternative, the STB sends the NID to the antenna for a given channel selected by the user. The antenna system compares the new NID to the current NID and either does not move if the NID does not change, or performs a move to the satellite slot corresponding to the NID for the new channel.

(44) FIG. 10 illustrates the process of scanning for multiple desired satellites, but being unable to locate all desired satellites. The scan 200 proceeds until the antenna locks onto a satellite candidate. The satellite ID (NID) is obtained from the STB 202 and compared to the set of desired satellite IDs. If the candidate is among the list, then the set-up page is updated 204 and the antenna compares the list of located desired satellites to the set of all desired satellites 206. If all desired satellites have been found, then a message to such effect is related to the STB so the STB stops sending queries to the antenna 208. The user is then ready to watch television. But if it is determined in 206 that all desired satellites have not been located, the antenna evaluates whether it has completed a scan procedure wherein and all satellite candidates have been evaluated 210. If no, then the scan proceeds to the next candidate. If yes in 210, then the STB is informed accordingly so that a message can be presented to the user to request a choice of watching available programming or repeating the scan process 212.

(45) Also when comparing the satellite NID in 202, the antenna determines whether it has completed its scan and evaluation of all satellite candidates 214. If the candidate satellite position ID is not among the set of desired satellite IDs (or cannot be identified) and if there are no other satellite candidates to evaluate, then the STB is informed so that the STB can display a message to the user to move the antenna and initiate a restart of the scan and acquisition process 216.

(46) FIG. 11 illustrates the process of updating the antenna's firmware. After power is supplied to the STB 218, the STB queries the antenna for its ID 220. The antenna reports its ID 222. The ID contains a firmware (or software) version identifier. The STB determines whether the software on the antenna is the current or correct version 224. If yes, the STB acknowledges the antenna ID 226 and displays the setup page for the user 228. If no in 224, then the STB displays a message to the user requesting that the antenna software be updated 230. In one embodiment, the software can be updated while connected to the STB using the STB interface to transmit the updated software to the antenna. In another embodiment, the antenna can be connected to a computer with access to the World Wide Web and the user can facilitate a connection with a software update server. In a further embodiment, the antenna is directly connected to the World Wide Web to receive updates from the software update server.

(47) The antenna control system is configured to react to several common modes of failure that might be encountered in use: 1. Failure resulting from user moving the antenna on purpose or by accident while sky searching

(48) Recovery can be automatic. The antenna control system verifies that none of the dish orientations for found desired satellites have changed before returning a sky scan complete status to the STB. If recovery cannot be automatic, a message can be displayed requesting whether the user wants to watch available programming OR move satellite antenna, re-set receiver and re-scan. 2. Failure resulting from user moving the antenna on purpose or accident after search is complete.

(49) The user can re-initiate the sky search by accessing the setup screen through the STB, or could reset or powering cycle the STB. For example, the loss of satellite signal will cause the STB to present the user with a setup screen from which a new search can be initiated. In some locations, such as the United States, it is possible to then send a new request for satellite ID rather than wait for a programming download to occur as would happen on a reset or power up. This expedites the re-acquisition. 3. Obstruction of 1 or more satellites while searching

(50) If less than all members of a set of desired satellites can be located, then the user can be presented with the option to watch the available programming OR move the antenna, re-set the receiver and re-scan. If no desired satellites are found, the user can be prompted to move the antenna, re-set receiver and re-scan. 4. Temporary obstruction

(51) Depending on where the antenna system is located, it may occur that a temporary blockage, such as a person walking in front of the system, may occur while in operation. In such instance the temporary obstruction would create a corresponding temporary error. Thus, a predetermined timeout duration is included in the antenna control system logic that must be satisfied before informing the STB and causing the STB to display a notice to the user that the antenna is attempting to acquire the satellites. 5. Temporary Power Loss

(52) If power is interrupted, the STB may provide the user with such a notice and give the user the option to continue watching television using the pre-interruption satellite information. The user can also be given the option to re-start a sky scan.

(53) As mentioned earlier, a setup/diagnostic screen displayed on the user's television allows the user to input selected data and customize the operation of the antenna system. One object of the screen is to minimize the amount of user input required to find satellites and watch TV, while still obtaining sufficient information to permit efficient system operation. In one embodiment, the user can be provided with a basic or initial screen to request the minimum operating information. An advanced screen selection option can also be provided so that the user can access advanced operating modes of the antenna system.

(54) In one example embodiment as shown in FIG. 4, the user selects geographical location on a set-up screen using a remote control and on-screen icons. Selection of region initiates search. In addition, the set-up screen can display the following information: 1. Confirmation that antenna system is installed and can communicate 2. Satellite service identification (e.g. DISH 500, DISH 1000, etc.) 3. Software revision status of antenna system software 4. Progress in accomplishing search task (e.g. busy or a percent complete) 5. Indication of satellites found 6. Vertical elevation 10 through 65 degrees (Numbers 10 thru 65) 7. Azimuth 0 through 12 (clock hours)

(55) The STB and antenna control system can communicate via the so-called DiSEqC communication protocol. This protocol is used by many satellite programming providers for accomplishing 2-way communication through a coaxial cable. It should be noted however, that the present invention is not limited to use of the DiSEqC protocol. Other communication methods and protocols between STBs and satellite antenna components can be used without departing from the scope of the invention.

(56) Another aspect of certain embodiments is that the two-way communication between the STB and antenna takes place over a single coaxial cable or communication conduit connecting the antenna to the STB. In addition, the satellite TV signals received by the antenna are also transmitted over this same single cable. Further the single cable can provide the power to the antenna necessary to operate the antenna, including powering the control system and the motors to aim the antenna's dish. By accomplishing all of the above items via a single coaxial cable, only one coaxial cable need be connected between the antenna and STB during setup. The antenna does not need any other connections. This is advantageous because fewer cables makes set up easier and faster, reduces cost, reduces weight, reduces likelihood of losing or forgetting components, there are fewer tripping hazards and the system after setup is more visually appealing (i.e. less cluttered). It also improves quality and reliability of the antenna.

(57) Referring to FIG. 12, a satellite television viewing system according to one example embodiment includes a portable antenna unit 300, a set top box (STB) 302, a television 304 and a power source 306. The television 304 and STB 302 are both electrically connected to the power source 306. Also, the STB 302 is connected to the television 304 via a communication cable 308. This cable 308 can be a coaxial cable, an HDMI cable, component cables or other suitable connection means known to those of skill in the art. A coaxial cable 310, or other suitable cable, electrically and communicatively connects the antenna unit 300 with the STB 302. An external fitting 312 can be provided on an exterior surface of the antenna's enclosure 314 to allow signal and power to pass through the enclosure while maintaining the sealed feature of the enclosed antenna unit.

(58) A plurality of feet 316 can be provided to the bottom of the enclosure to facilitate the antenna unit sitting on a surface such as the ground or a table, or to facilitate attachment to a bracket.

(59) Some portions or all of antenna enclosure may comprise an electromagnetic wave permeable material that permits the inbound satellite broadcast energy to pass through the enclosure 314 with minimal loss. The enclosure may be sectioned into a top or cover portion 318 and a bottom or base portion 320 to facilitate access to the antenna components enclosed completely within the enclosure. The enclosure protects the antenna control system, motors and other components from moisture, dirt, sand, other debris and from impacts that might damage the enclosed components.

(60) A handle 322 or other carrying means can be provided to, or defined in, the enclosure to facilitate carrying by a single hand of a user.

(61) Referring to FIGS. 13-15, certain internal details of the antenna device are shown according to one example embodiment. However, the internal components can have other configurations, shapes and sizes without departing from the scope of the invention. The satellite television antenna system includes a parabolic reflector dish 350 and a subreflector 352 positioned forward of the dish. The dish collects incoming satellite broadcast signals by reflecting them forward to a focal point. The subreflector is located adjacent to the dish's focal point to reflect the collected signal rearward through a feed or guide tube 354 and on to a low noise block (LNB) converter 356 located behind the dish. The LNB converter amplifies the signals and converts them from microwaves to low frequency signals that are transmitted to the enclosure junction 312 and then onward through the communication conduit to the STB. The STB converts and decodes the television signals received through the conduit so they can appear on the screen of a television.

(62) In one embodiment, orientation or positioning of dish 350 is carried out by a motorized elevation drive system, which includes an elevation motor 360, and a motorized azimuth drive system, which includes an azimuth motor 362, that are each controlled by the antenna control system. The antenna control system includes a microprocessor and physical memory disposed on a control board 358, which is located inside of the enclosure. The memory can be either both onboard the processor or separate from the processor, or a combination of both. The memory stores the operating software code for the antenna system, which is executable by the microprocessor. The microprocessor (processor) then communicates with (or selectively energizes) the motors 360 and 362 to selectively orient the dish. The microprocessor also controls communication with the STB.

(63) A GPS receiver can also be provided to the control board 358, or other portion of the antenna unit inside of the enclosure) according to certain embodiments. The GPS receiver in such embodiments communicates with the processor to provide data that the processor uses to determine elevation and/or azimuth orientation data for the dish corresponding to the geographic location of the antenna device.

(64) While the invention has been described in connection with what is presently considered to be the most practical and preferred example embodiments, it will be apparent to those of ordinary skill in the art that the invention is not to be limited to the disclosed example embodiments. It will be readily apparent to those of ordinary skill in the art that many modifications and equivalent arrangements can be made thereof without departing from the spirit and scope of the present disclosure, such scope to be accorded the broadest interpretation of the appended claims so as to encompass all equivalent structures and products.

(65) For purposes of interpreting the claims for the present invention, it is expressly intended that the provisions of Section 112, sixth paragraph of 35 U.S.C. are not to be invoked unless the specific terms means for or step for are recited in a claim.
