Changing the Video Input/Output Methods
Additional Procedures A-3
A.1.2 Using S-Video Output
To switch to higher-quality S-Video output, follow these steps:
1) Unplug the composite video connector. Then, connect your S-Video
connector to the S-Video output port, which is to the right of the
currently-used composite video output port.
The DVEVM kit does not include an S-Video cable. In addition, you
will need a video display with an S-Video input.
2) On the kernel command line, you can configure the EVM to select
both NTSC vs. PAL and the S-Video output format (see Section
4.3.7, Configuring the Boot Setup for PAL Video Users). For
example, if you want both NTSC and S-Video output, use the
following:
davinci_enc_mngr.ch0_output=SVIDEO davinci_enc_mngr.ch0_mode=NTSC
If you want both PAL and S-Video, use the following:
davinci_enc_mngr.ch0_output=SVIDEO davinci_enc_mngr.ch0_mode=PAL
