The 8712 is a versatile video output card available for the MRD 3187B. It provides two user selectable serial digital (SMPTE 259M, or SMPTE 292M) outputs and one component RGBHV or YPbPr/Composite NTSC & PAL output. Eight pairs of audio can be embedded into the serial output on group 1, 2, 3 and 4. Closed captioning found within the transport (608/708B) can be embedded into the serial video output. NTSC closed caption, detected in the transport stream, can be inserted on line 21.
Note: This card requires the 8733 decoder board.
