Appendix B Setting Up S-Video 79
S-Video Along With Normal Video
This option allows S-video on one video data stream and a normal screen on the
other stream.
There can only be two active video outputs at any given time: Either two 13W3
outputs, or one 13W3A output and one S-video output with 13W3B unused.
This setup shares the memory and video resources between the two streams.
Multisample depth could be reduced.
1. Set the resolution and sample density for the first (normal) stream.
For example, type:
Note – Notice the
0b
above. This is not the same resolution that is used for the
default subdevice (
zulu0
). This resolution needs to be set up independently of
zulu0
.
Note –
Any valid resolution can be used for
zulu0b
. The larger the resolution is,
and higher its sample density, however, the less memory is available for
multisampling in the S-video channel.
2. Set the resolution and sample density for the second stream.

For NTSC, type:
■
For PAL, type:
In the preceding command lines, more memory is allocated for the S-video stream.
