A video system includes a first video device. The first video device includes a video output port and an arbitrary data scrambler. The first video device transmits a video stream through the video output port. The video output port is configured to insert video timing reference values into the video stream. The arbitrary data scrambler is configured to scramble non-video data for transmission in the video stream such that unscrambled non-video data containing video timing reference values is transformed, without information loss, to scrambled non-video data containing no video timing reference values.

System and method for transferring non-video data over a video interface

A video transcoding system includes a video decoder, a video encoder, and a video interface. The video decoder is configured to decode a received video signal. The video encoder is configured to encode video data decoded from the received video signal by the video decoder. The video interface couples an output of the video decoder to an input of the video encoder and is configured to transfer video data having a first chroma subsampling ratio. The video decoder is further configured to provide video data having a second chroma subsampling ratio that includes fewer chrominance samples than the first chroma sampling ratio to the video interface, and to provide non-video information generated from decoding the received video signal to the video interface using video interface bandwidth usable based on a difference between the first chroma subsampling ratio and the second chroma subsampling ratio.

System and method for video transcoding

A system and method for allocating video processing tasks over multiple video processors include an apparatus. The apparatus includes a plurality of video processors. Each video processor includes a first processor that processes video data and manages buffers used in conversion and displaying video data. The video processor includes a second processor that performs video data signal processing and manages buffers used in processing video data. The apparatus also includes a switch coupled to each video processor, as well as video inputs and video outputs. A third processor coupled to the switch, and a memory coupled to each video processor and to the third processor, are also part of the apparatus. The switch selectively couples a video processor to a video input or a video output, the third processor configures the switch based on processing requirements of each video stream, and the memory buffers and stores video data.
