Changing the Video Input/Output Methods

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.

S-Video

OUT

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
