<p>A video system for processing compressed video data into composite data, the composite video data corresponding to a standard composite video signal type selected from a plurality of standard types including at least one of an NTSC composite video signal type and a PAL video signal type, including a processor (34), a standard video decompressor (32) and a video interface (40). 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 a composite video signal. The video interface includes a VBI data generator (60) to process the VBI data into VBI signal, a mixer (50) 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 and then output Y, U and V data.</p> |
