Hi world,
Do you know any ready-made chip that would allow us to transform a 8-bit RGB
+ 2 bits Vsync/Hsync image stream (coming from a CMOS image sensor) into a
BT.656 8-bit stream, I mean in EAV/SAV mode (this mode allows to embbed the
synchronisation signals into the digital video stream itself, using reserved
video values) ? As a background we have a "dumb" CMOS sensor and need to
connect it to a processor image capture port which seems to only understand
EAV/SAV.
I guess than one answer will "use an FPGA and do it yourself", but I would
prefer an off-the-shelf solution... or an existing VHDL code...
Thanks for your help,
Yours,
Robert

Thanks Martin, we'll check

Sorry to be so late in replying, but I've been on vacation.

Look up Brooktree (now part of Conexant Systems), Integrated Circuit
Systems Inc (now part of IDT) or Pixel Semiconductor.
