Example network-based adaptive streaming media parameter adjustment methods and apparatuses are disclosed. One example method includes receiving, by an access network device, media QoS information from a session management network element, where the media QoS information includes at least two bit rate indicators and QoS requirement information corresponding to each of the bit rate indicators. The access network device determines, based on a current network condition and the media QoS information, a target bit rate indicator from the at least two bit rate indicators. The target bit rate indicator is sent to a terminal or a video server, where the current network condition meets a network requirement for transmitting streaming media data at a bit rate indicated by the target bit rate indicator.

The present invention provides a control method applied to an electronic device is disclosed, wherein the electronic device includes a processor and a wireless network module, and the control method includes the steps of: generating a determination result by determining if the wireless network module needs to transmit a packet; and when the determination result indicates that the wireless network module needs to transmit the packet, reducing a frequency of a clock signal used by the processor during a packet transmission.

A system and method for providing non-guaranteed channels in a switched digital video network using multicast adaptive bitrate (ABR) streaming. In one implementation, upon receiving a request for a non-guaranteed channel is received from a subscriber station (e.g., a set-top box or STB), a bandwidth pipe modeling process is operative to model a bandwidth pipe corresponding to each edge QAM device configured to support non-guaranteed channels for selecting a particular edge QAM device that can best accommodate the requested non-guaranteed channel. Bitrates of MABR streams of existing channels of the selected edge QAM device may be adjusted in order to accommodate a particular MABR stream at chosen bitrate of the requested non-guaranteed channel. IGMP Join operations may be effectuated, as needed, to join MABR streams of the existing channels and the requested non-guaranteed channel to correct IGMP group(s). A channel change response message including one or more channel frequencies, if the change request is accommodated, may be transmitted to the requesting subscriber station.

In one embodiment, a method includes generating a request for media at a publisher and transmitting the request to a media pipeline, the media transmitted from the media pipeline to a distribution pipeline. The media pipeline includes a chain of streaming media processing components, the chain dynamically configured by the publisher. An apparatus and logic are also disclosed.

A transmission apparatus includes a transmission unit configured to transmit content to an external apparatus through a cable; an information acquisition unit configured to acquire cable-length information that represents a cable length to the external apparatus; and a controller configured to control an operation of the transmission unit based on the cable-length information acquired by the information acquisition unit.

This invention relates to an encoding/transmitting apparatus that is used to transmit moving-picture data from a transmitting side to a receiving side through a transmission path and to subject the moving-picture data to streaming in the receiving side. The apparatus has an external-output request determining unit (16) that monitors the state of a network. If the network assumes an undesirable state, the unit (16) causes a multiplex output unit (15) to stop multiplexing data. When the network assumes a good state, the unit (15) starts multiplexing the data again. A video encoding unit (11) and an audio encoding unit (12) keep encoding data, whether the multiplex output unit (15) is multiplexing data or not. When the area occupied by encoded data in an encoded-video-data storage unit (13) and the area occupied by encoded data in an encoded-audio-data storage unit (14) exceed a predetermined value, the units (11) and (12) stop encoding data, and wait until the area occupied by encoded data sufficiently decreases.

A satellite reception assembly may include a housing configured to support receipt and handling of a plurality of satellite signals. The housing may include circuitry incorporating integrated stacking architecture for supporting and/or providing channel and/or band stacking whereby particular channels or bands, from multiple satellite signals that are received via the satellite reception assembly, may be combined onto a single output signal that may be communicated from the satellite reception assembly to a gateway device for concurrent distribution thereby to a plurality of client devices serviced by the gateway device.

An aspect of the present invention provides a server for controlling a camera video image to be distributed to an audience terminal for multi-camera video image distribution service for cyclic distribution of camera video images in a plurality of points of view to audience. The server includes a selector and a decider. The selector selects a plurality of candidates in each of selection opportunities that allow each audience member to select the camera video image to be distributed to the audience terminal. The decider decides the camera video image to be distributed to the audience terminal based on information indicating one of a plurality of options selected by each audience member. At least one of the plurality of candidates selected in at least one of the selection opportunities includes a common camera video image regardless of camera video images viewed by the audience when the plurality of candidates are selected.

One or more circuits for use in a transceiver that is collocated with a satellite dish, may receive a satellite signal carrying media content, and remove content protection from the received media content. After removing the first content protection, the one or more circuits may apply second content protection to the media content. The content protection applied by the one or more circuits may adhere to a different protocol, utilize different keys, and/or otherwise be distinguishable from the content protection that was removed. After applying the content protection, the one or more circuits may transmit the media content onto one or more links between the satellite dish and one or more client devices. The removal of the content protection may comprise descrambling and/or decrypting the media content. The application of the content protection may comprise scrambling and/or encrypting the media content.

Systems and methods for real-time transmission of data streams are disclosed. A controller receives data representing selected stream parameters from a browser residing on a computing device. The controller transmits the received data to a video transmitting device. A transcoder receives a first data stream generated according to the selected stream parameters from the video transmitting device. The transcoder generates a second data stream from the first data stream, the second data stream formatted for browser display; and then transmits the second data stream to the browser. A user may remotely control the video transmitting device using the browser. A user may view data streams from multiple video transmitting devices using the browser.
