Abstract: A digital multi-standard TV composite video encoder is provided for converting digital RGB signals, such as those generated by high color resolution TV game machines, into analog composite video signals that can be accepted by TV systems of various standards including NTSC-M, NTSC 4.43/50, NTSC 4.43/60, PAL-B/G/I/D, PAL-M, and PAL-N. The present invention integrates encoder and TV game machine in a single chip of integrated circuit, which employs only one single crystal oscillator and three jump lines for selection of the six standards.
