NTSC/PAL Video Decoder

REAL TIME CONTROL INTERFACE

The Real Time Control Interface (RTCI) outputs timing infor-

mation for a NTSC/PAL encoder as BT.656 ancillary data.

This allows the encoder to generate “clean” output video.

RTCI information via BT.656 ancillary data is shown in Table

8. If enabled, this transfer occurs once per line and is com-

pleted before the start of the SAV sequence.

The PSW bit is always a “0” for NTSC encoding. During PAL

encoding, it indicates the sign of V (“0” = negative; “1” = pos-

itive) for that scan line.
