    摘要： HDMI transmission of uncompressed image data, on which dynamic range processing is performed, is performed from an HDMI source device and a display in appropriate luminance is performed in an HDMI sink device. When HDMI input switching is performed, a television receiver 13 transmits transmission request information to an HDMI source device in a destination of the input switching and acquires dynamic range conversion definition information of uncompressed image data at intended timing. Also, when it is possible to acquire the dynamic range conversion definition information of the uncompressed image data, the television receiver 13 minimizes transmission of the dynamic range conversion definition information from a BD recorder 11 by sending reception recognition information back.

    摘要： A device and a method for multiplexing a plurality of bit streams, a device and a method for decoding a multiplexed signal and a recording medium storing a program for multiplexing a plurality of bit streams are adapted to carry out a dividing step for dividing said second bit stream into predetermined units, an adding step for adding a start code to each of said units obtained by dividing said second bit stream and a multiplexing step for defining a user operable region in said first bit stream and multiplexing and recording at least part of said second bit stream on said user operable region. As a result, a picture signal can be decoded with minimal processing steps because a conventional coding system can be used without modification.

    摘要： A video signal receiving apparatus comprises a HDMI receiver, signal processing section and control section. The HDMI receiver separates a digital signal conformable to HDMI standards into video component and audio component, determining whether a received digital video signal is a RGB or YCbCr signal, and changing its setting in accordance with the determination result. The signal processing section decodes video signal and audio signal separated by the HDMI receiver to restore analog video signal and audio signal. The control section changes the setting of the HDMI receiver by an operation.

    摘要： A player model (1) includes an output section (10) that reads out a source packet having a transport packet and arrival time stamp from TS1 and TS2 connected seamlessly to each other and outputs the transport packet according to the arrival time stamp, and a decoder (20) that decodes the transport packet. The output section (10) inputs the transport packet according to the arrival time stamp of the source packet to the decoder (20). The decoder (20) includes an audio buffer TBn having a capacity capable of buffering the audio data corresponding to the time required for inputting I picture, which is the first picture of TS2, to a video buffer TB1.

    摘要： A process for switching television programs is wherein it detects (8, 9) and then stores (10) the appended data of intra type of programs other than the selected program, selects (10) and decodes (12), upon a command (14) for the switching over to a new program, the stored appended data relating to this new program, and temporarily transmits (13), while awaiting the decoding and transmission of the current data of the new program, the decoded appended data.Applications relate for example to the perusing of programs.
