Texas Instruments TMS320DM6446 DVEVM v2.0 manual Using Component Video Output, Pr Pb

Changing the Video Input/Output Methods

A.1.3 Using Component Video Output

To switch to highest-quality component video output, follow these steps:

1)Connect your component video connectors to the connectors in a square on the far left of the board. Instead of connecting one connector as with composite video, connect the YPrPb connectors as shown here.

Pr Pb

Y

The DVEVM kit does not include a 3-connector cable used for component (YPrPb) video. The cable you use may have red, green, and blue connectors, but you should be aware that the Y, Pr, and Pb signals used by component video do not correspond to RGB signals. In addition, you will need a video display with component video inputs.

2)On the kernel command line, you can configure the EVM to select both NTSC vs. PAL and the component video output format (see Section 4.3.7, Configuring the Boot Setup for PAL Video Users). For example, if you want both NTSC and component video output, use the following:

davinci_enc_mngr.ch0_output=COMPONENT davinci_enc_mngr.ch0_mode=NTSC

If you want both PAL and component video, use the following:

davinci_enc_mngr.ch0_output=COMPONENT davinci_enc_mngr.ch0_mode=PAL
