Hi,
has anybody an idea how to switch off sending sync signals on the CVBS (TV/SD) output? We're using S-Video in PAL or NTSC format out off an DM8148 HDVPSS.
I found the video processor register documentation in the DM38x DaVinci™ Digital Media Processor High-Definition Video Processing Subsystem (HDVPSS) User's Guide (spruhi7a.pdf) and the corresponding sources and currently I am setting the register SD_VENC_cvbs0, namely the bits 27-16 and 11-0 to 0, but still the monitor shows a (albeit distorted and totally unstable) picture.
Is there another way to suppress sync on the TV out? When I just switch off the driver, the monitor still syncs on a signal. The reasoning behind this is that some displays are switching off the backlight too when they can't sync.
regards,
Uli
