Abstract
A video system for processing compressed video data into composite video data, the composite video data corresponding to a standard composite video signal type selected from a plurality of standard types, the plurality of standard types including at least one of an NTSC composite video signal type and a video signal type, includes a processor, a standard video decompressor and a video interface. The standard video decompressor processes the compressed video data into decompressed video data and user data, the user data having VBI data encoded therein. The processor culls the VBI data from the user data. The video interface processes the decompressed video data and the VBI data into the composite video data with the VBI data encoded therein. The video interface includes a VBI data generator to process the VBI data into VBI signal data, a mixer coupled to the video decompressor to receive the decompressed video data, the mixer being coupled to the VBI data generator to receive the VBI signal data the mixer providing output Y, U and V data during an active portion of a scan line, and circuitry to process the Y, U and V data into the composite video data.
