Abstract:
A video compression circuit, comprising:a video decoding block that receives an analog video signal and digitizes the analog video signal prior to separating vertical blanking interval data from video data in the digital video signal to form a video data stream and a vertical blanking interval data stream; a video encoding block operably coupled to the video decoding block, wherein the video encoding block encodes the video data stream to produce a compressed video data stream; a vertical blanking interval encoding block operably coupled to the video decoding block, wherein the vertical blanking interval encoding block isolates a selected vertical blanking interval data type from the vertical blanking interval data stream to produce a selected vertical blanking interval data type stream; and a video combination block operably coupled to the video encoding block and the vertical blanking interval encoding block, wherein the video combination block combines the compressed video data stream with the selected vertical blanking interval data type stream to produce an enhanced video data stream.
