A sink device is bi-directionally communicably connected to the source device. The sink device includes a first memory, and a controller. Stored in the first memory is a plurality of pieces of audio format information including information representing an audio format that the sink device can process. The controller selects, from among the plurality of pieces of audio format information stored in the first memory, one piece of audio format information corresponding to receiver format information representing an audio format that a receiver device connected to the sink device can process. The controller then outputs the selected audio format information to the source device.

An analysis device includes a controller. The analysis device receives moving images sent from a plurality of imaging devices, analyzes the received moving images, and sends an analysis result of a moving image to, among a plurality of display devices, a display device which has made a request to display so that the display device displays the analysis result. The controller controls a processing order of reception processes and analysis processes on moving images sent from the imaging devices according to degrees of priority preset for the respective imaging devices.

Techniques described herein automatically identify, in a multimedia content, an advertiser from which an advertisement in the multimedia content originates and/or a brand to which the advertisement pertains. The system determines whether the identified advertiser and/or identified brand is specified in a not to be displayed list and if so, performs at least one of: presents alternative content during the time interval that the advertisement occupies in the multimedia content or skips over the advertisement in the multimedia content.

A signaling method of video content and services broadcast by to a multitude of reception devices, the contents being encoded into data packets transmitted in a transport stream associated with a signaling stream is disclosed that comprises an insertion step of a unique identifier associated with each of the video contents or services in the signaling stream; an insertion step of the unique identifier into packets of the transport stream transmitting the video content or service corresponding to the unique identifier. Advantageously, the unique identifier is derived from a characteristic of the content among the title of the video content or service, the date and theoretical continuous broadcast time of the video content or service. A method for recording and a recording device using the signaling is further disclosed.

A transmission apparatus includes: a video-signal transmission section transmitting a video signal to an external apparatus by a differential signal through a plurality of channels through a transmission line; and an information transmission section transmitting image-quality adjustment information corresponding to the video signal transmitted by the video-signal transmission section to the external apparatus through a communication path formed by a pair of differential transmission lines included in the transmission line.

Techniques are provided for converting live presentations into electronic media and managing captured media assets for distribution. An exemplary system includes capture devices that capture media assets of live presentations comprising a session, including image data of sequentially presented visual aids accompanying the live presentations and audio data. Each capture device has an interface for real-time image data marking of the image data for identification of individual images and session marking of the image data for demarcation of individual presentations of the session. A centralized device processes the captured media assets and automatically divides the captured media assets into discrete files associated with the individual presentations based on the session markings. An administrative tool manages the processed media assets to produce modified presentations and enables modification of the visual aid images identified by the image data markings. A production device formats the modified presentations for distribution on distribution media.

A source device that provides contents to a sink device and a communication method thereof are provided. The communication method of the source device includes: transmitting a communication signal including a High-bandwidth Digital Content Protection (HDCP) signal to the sink device; determining a communication status with the sink device using an HDCP communication result received from the sink device; and adjusting the communication signal according to the determined communication status. Therefore, the communication method can provide a user with optimized contents.
