Audio + DVI = HDMI

February 12, 2006 10:56 AM

Is there product which combines audio with DVI video into an HDMI output?

I have a DVD player with an DVI video output and a variety of audio ouputs: optical digital, coaxial digital, and analog stereo (red and white RCA. My new television accepts HDMI input, with no DVI plus audio input port. Is there a product which will combine the DVI video output of my DVD player with one of the audio output streams into an HDMI video+audio stream?

The audio signal in HDMI is hidden inside the video signal. The device you want would have to decode the DVI and re-encode with the audio mixed in. Any device that does this is not going to be cheap.

I don't think this is possible with a cheap adapter, as with HDMI, the audio data is actualy multiplexed along with the video in the TMDS signal. There may be a box that could multiplex the audio but it'd probably be expensive. On preview, what cillit bang said.

You could feed DVI straight into HDMI with a simple cable/adapter, and run the audio separately to whatever is driving your sound system.
