[linux-dvb] Adding SDI SMPTE 259M interface to DVB card

[Emil Naepflein <Emil.Naepflein@philosys.de>]

Hi,

has someone already thought about adding a SDI video interface to the
DVB-S card?

The AV7111 has a digital video output port (YCOUT8bit, YCCLK) which
outputs 8 bit 4:2:2 data with a 27 MHz clock. 

Is this port normally activated in the firmware?
The spec also says that if the 32-bit EBI is used the digital out is not
available.

I would assume that this data stream is already feed to the SAA7146A
into its D1 input to provide the data for the frame buffer. So the only
thing to do would be to tap the signals and convert it into SMPTE 125M
component digital video stream.

I would like to improve the image quality by directly feeding the
digital video stream from the MPEG2 decoder into a video scaler.

Any ideas?

Thanks,
Emil
