S-Video
The MAX9670/MAX9671 support S-video from the set-
top box to the TV, set-top box to the VCR, and VCR to
the set-top box. S-video was not included in the original
SCART specifications but was added afterwards. As a
consequence, the luma (Y) signal of S-video shares the
same SCART pin as the CVBS signal. Likewise, the
chroma (C) signal shares the same SCART pin as the
red signal. The pins that can carry both CVBS and luma
have Y/CVBS in their names, and the pins that can
carry red and chroma have R/C in their names.
Now, the Y/CVBS signals are full duplex while the R/C
signals are half duplex. Therefore, S-video is limited to
being half duplex. The MAX9670/MAX9671 have to
transmit a chroma signal and receive a chroma signal
