To provide a practical technique with which video data can be transmitted with a wireless LAN from a video output device having a function of processing video data to a terminal device having a display unit such as a mobile terminal.

A video output device 100 outputs video data via a line. A video processor 200 transmits compressed data obtained by JPEG-compressing data of the received video for each frame data to a terminal device 300 from a wireless LAN communication unit, from time to time. The terminal device 300 decompresses the compressed data to restore the frame data, and displays an image based on the video data on a display unit 301.

Disclosed are methods and apparatus for augmenting a user's multimedia consumption experience. The methods comprise while the user is consuming the multimedia presentation using a first device, that device provides (to one or more remote processors) information that may be used to identify a relevant location. The one or more processors use this information to identify the location and acquire a virtual environment. This virtual environment may be a virtual representation the location. The virtual environment is presented to the user on a second (companion) device. Using the second device, the user may explore the virtual environment and interact with virtual objects therein.

A method for supplying an N-screen service by a main N-screen device in a broadcast system is provided. The method includes receiving an Application Information Table (AIT) including a screen_type indicating a type of N-screen device in which a broadcast service application will be run from a broadcast service provider, and one of running the broadcast service application based on the screen_type, performing an operation related to running the broadcast service application by considering a connection relationship between the main N-screen device and a sub N-screen device based on the screen_type, and discarding the AIT based on the screen_type.

A head-mounted electronic device and an audio processing method includes a fixing unit, by which the head-mounted electronic device can be worn on the wearer's head; a processing unit, provided in the fixing unit and configured to perform audio processing and output a first audio signal; a first bone conduction unit, provided on the inner side of the fixing unit, configured to generate vibrations according to the first audio signal, so that the wearer can hear the first audio through the generated vibration, wherein the inner side of the fixing unit is the side which is closer to the wearer's head when the head-mounted electronic device is worn on the wearer's head, and when the head-mounted electronic device is worn on the wearer's head, the first bone conduction unit contacts the wearer's head, so wearer can sense vibrations generated by the first bone conduction unit.

A profile provider: (i) associates a primary online device (OD1) with a set-top box (STB); (ii) a location of OD1 at some point in time is estimated to be “near” the STB, thereby establishing a STB proxy location; (iii) one or more secondary online devices (OD2s) are observed to be located “near” the STB proxy location and are associated with the STB; and (iv) a television advertisement is selected to be directed to the STB, which selection is based at least in part on profile information linked to one of the associated OD2s. The method can be particularly advantageous in situations wherein: the STB is not connected to any computer network; the STB is not ever connected to the same local area network as OD1 or OD2; or television service (used by the STB) and online access (used by OD1 and OD2s) are provided by different service providers.

A broadcast audience interaction and feedback system may discover and activate a recording function of a portable device of a user to record audio and/or video of media content output by a media device in proximity to the user. The audio or video data may be used to identify the content by matching audio or video fingerprints or signatures of the data recorded by the portable device with separately generated signatures or fingerprints associated with the content. Additional entities may be automatically associated with the content via capturing of metadata or closed captioning data during the content, OCR of displayed text in the content, or detection of other such entities. In some implementations, the portable device may also capture feedback from the user, including cheering, applause, and laughter, as well as explicit questions or comments, voting choices, etc. The feedback may be identified, and queries generated or additional functions performed based on the identified feedback, the identified media content, and/or one or more entities associated with the identified media content.

Customized recommendations of multimedia content streams are provided herein. A method can include facilitating, by a network device of a wireless network and comprising a processor, an output of a recommendation of a first multimedia content stream at a communications device based on a monitored interaction determined to have been performed by an identified entity at the communications device. The method can also include facilitating, by the network device, a first transmission of the first multimedia content stream to the communications device in response to an acceptance of the recommendation of the first multimedia content stream received from the communications device. The first multimedia content stream can be renderable for consumption at the communications device.

An image display system includes a first terminal device and with a second terminal device whose usable function range is smaller than a usable function range of the first terminal device. The image display system includes a display projection unit, a communication unit that establishes wireless connection with the first and second terminal devices, a control unit that manages the wireless connection, and a connection control image generating unit. The control unit and the connection control image generating unit generate a terminal connection image including information for connecting the second terminal device with the image display system, based on terminal connection permission information that assigns the second terminal device whose wireless connection with the display system is permitted, the terminal connection permission information being transmitted from the first terminal device. The display projection unit displays the terminal connection image.

Systems and methods for determining whether a first electronic device detects a media item that is to be output by a second electronic device is described herein. In some embodiments, an individual may request, using a first electronic device, that a media item be played on a second electronic device. The backend system may send first audio data representing a first response to the first electronic device, along with instructions to delay outputting the first response, as well as to continue sending audio data of additional audio captured thereby. The backend system may also send second audio data representing a second response to the second electronic device along with the media item. Text data may be generated representing the captured audio, which may then be compared with text data representing the second response to determine whether or not they match.
