What 'DTVp' means?

GNU Radio
1

Hello,

Excuse me for my ignorance, what does ‘DTVp’ means here?

CVBS is composite output if the tuner is working in analog mode, but I
don’t know what is ‘DTVp’ in digital mode. Is possible to demodulate
that using GNU Radio (writing a block, obviously)?

Regards,
Carlos

From the looks of things, I believe it’s the positive channel of a
differential signal carrying the DTV information (DTVp and DTVn).
Possibly LVDS? Either way, most likely just some type of digital
differential signaling.

It appears as if the demodulation is already done in the “demodulation
co-processor” block within the chip? You may want to contact the IC
manufacturer for a datasheet.

Good luck!
