No one ever talks about Audio/Video here, so I guess it's my turn or find another forum to help me.
I need to encode L/F to one of the following audio formats "on the fly" : mpg2; mpeg2 AAC; mpeg4 AAC; AC 3 (Dolby Digital)
I really believe I need AAC or Dolby Digital. It would probably make sense to mix L/R to 5.1 AC3. The AC3 spec is here:

I also have the choice of 64, 128, 96, 128, , 192 256, 320 kbps which I think is: 1,2,3,4,5,6,7; the .1 is always assumed. e,f, 128 is 2.1, 128 is 5.1 and 320 is 7.1
Could be wrong though. ATSC TV supports 5.1 audio. I think the audio sample rate is mixed in there somehow. The 320 is an outlier.
If this **broken link removed** thing had a spec sheet I could understand
So, it says this:
Real-Time HDMI Audio Encoding
This HDMI audio processor provides users with easy external ways to:
I will have a standard L/R audio source, an AM/FM tuner to keep things simple that I want to distribute through GIZMO A. GIZMO A only accepts HDMI.
GIZMO A is a 4*ATSC RF modulator and IPTV multicaster. GIZMO A, I have.
I also have an web page controlled ATSC and IPTV tuner. That looks easier to integrate.
I need a GIZMO C that generates HDMI video and inserts up-mixed AAC 5.1 audio from a L/R source. I'd rather not have a blue screen, but a black screen. I don't know if black screens are legal. Thus having a blue screen makes part of it testable.
I THINK I have an encoded RF signal from an HDMI tuner output. I've verified signal strength, but not signal.
My first HDMI TV is still sitting in a box.

Real-Time HDMI Audio Encoding
This HDMI audio processor provides users with easy external ways to:
- INSERTS optical audio of PCM 2-CH, Dolby Digital 5.1, DTS 5.1 type input to HDMI output
- INSERTS PCM AUDIO FROM A stereo L/R input to HDMI output
- transmit audio through HDMI cable for home theater, studio setup or public broadcasting
