NTSC Composite and S/PDIF from Nehemiah
I've mostly been playing with the Asus
A7N266-VM
board since it arrived, but a
conversation with a co-worker got me wondering this morning about the RCA
jack on the back of the
Nehemiah board I have.
There's a jumper on the board that selects whether you get composite video
or S/PDIF audio output. I've been annoyed by this since I really want both...
A quick check with my trusty multimeter confirms that the jumper is merely selecting which trace gets routed to the center pin of the RCA socket! So, to use both, all we need to do is fashion a cable to pick up the other signal and a ground from somewhere and route it to another RCA socket. Cool. Could even wire in an optical interface for the S/PDIF like the one provided with the Asus board, I suppose...
With the ongoing work to enable the mpeg2 decoder in the CLE266, that board may end up being a pretty cool standalone frontend for mythtv someday...
