摘要： In an embodiment, a media source combines reference code values and mapping function parameters for mapping functions into video frames originally designated to carry pixel values. The video frames are delivered to a downstream device such as a media sink in an encoded video signal. The media sink extracts the mapping function parameters for the mapping functions from the encoded video signal and applies the mapping functions as a part of display management operations to map the reference code values to the mapped pixel values appropriate for the media sink. The mapped pixel values can be used to render images as represented by the reference code values.

摘要： Maintaining synchronization of encryption processes at devices during transmission of encrypted data over a communication link is provided. Cipher link maintenance characters are sent from a source device to a sink device. A local cipher link maintenance character generated at the sink device for decrypting the encrypted data can be adjusted according to the cipher link maintenance character. After authentication, cipher link maintenance characters corresponding to units (e.g., frames) of the encrypted data are sent along with the units of the encrypted data. When a transmission error occurs during transmission of the encrypted data, cipher link maintenance characters can be used to correct the error in a local cipher link maintenance character generated at the sink device. Hence, even if the transmission error occurs in the communication link, the sink device can resolve the transmission error and maintain the synchronization of encryption processes at the source and sink devices.

摘要： A video processing device (100) for processing 3D video is coupled to a 3D display device (120). The device receives the 3D video data according to a high resolution interlaced 3D format. A video processor (106) generates a 3D display signal according to a display format. 3D display capability data indicates at least one interlaced 3D display format accepted by the 3D display device, the interlaced 3D display format having a lower resolution than the high resolution interlaced 3D format. The device has a storage unit (21,31) for storing the 3D display capability data and 3D conversion capability data. The 3D conversion capability data indicates a capability of the video processing device for interlaced down conversion for enabling a selection mechanism to control the processing of the 3D video information by selecting the interlaced 3D display format and the interlaced down conversion. Advantageously the user is provided with the best possible 3D view.

摘要： The present invention makes it possible to perform transmission of stereo image data between devices in a favorable manner. A source device (disc player 210) receives E-EDID from a sink device (television receiver 250) via DDC of an HDMI cable 350. This E-EDID contains information on 3D image data transmission modes that can be supported by the sink device. On the basis of the information on 3D image data transmission modes from the sink device, the source device selects a predetermined transmission mode from among the 3D image data transmission modes that can be supported by the sink device. The sink device transmits 3D image data in the selected transmission mode to the sink device. For the convenience of processing in the sink device, the source device transmits information on the transmission mode for the 3D image data transmitted, to the sink device by using an AVI InfoFrame packet or the like. The sink device processes the 3D image data received from the source device in accordance with its transmission mode, thereby obtaining left eye and right eye image data.

摘要： Damaging a device that is not compatible with a functional extension is to be avoided.
A signal is transmitted to an external device through a transmission channel. A data block containing capability information indicating existence/non-existence of compatibility with an extended function is received from the external device through the transmission channel. A layer field that indicates the connection layer is provided in this data block. A check is made to determine whether all the devices existing in the path are compatible with the extended function based on the value of the layer field provided in the data block, and the contents of the transmission signal are then determined.

摘要： An object of the invention is to permit quick control of the operating state of a source equipment side from sink equipment. A television receiver (sink equipment) 100 and an amplifier (repeater equipment) 200 are interconnected over an HDMI cable 610, and the amplifier 200 and a DVD recorder (source equipment) 300 are interconnected over an HDMI cable 620. Each of the pieces of equipment includes, in addition to an HDMI receiving unit and an HDMI transmitting unit, a high-speed data line I/F included in a bidirectional communication unit that uses predetermined lines of the HDMI cable. The bidirectional communication unit is used to transmit channel selection information, a remote control code instructing recording, "theater mode" designating information, a remote control code, or the like from the television receiver 100 to the audio amplifier 200 or DVD recorder 300. The operating state of the audio amplifier 200 or DVD recorder 300 can be quickly controlled from the television receiver 100.
