Does HDMI carry the audio signal as well?
So if I use a HDMI cable for my HDTV box do I run a digital cable for the surround sound?
Hi Bob - HDMI combines video and multi-channel audio into a single cable. However, most TV's will not pass DD5.1, so I would typically recommend running HDMI from your digital box into your TV, and running seperate optical audio or digital coax into your receiver for surround sound.
That is what I thought but just wanted to make sure.
Do you think it would be worth switching from Component cable to the HDMI with my HDTV digital box?
Hi Bob - HDMI was not designed to provide superior picture quality to component video. They should really be considered as "equals" in terms of PQ. Any differences you see are likely due to differences in equipment or the way the various inputs are calibrated (or not calibrated) on your TV, not the connector.
However, HDMI may provide a superior picture when viewed on a fixed pixel display (like LCD, DLP, Plasma, LCoS) since these are digital displays, so the signal remains digital "all the way". CRT-based TVs are analog, therefore a superior picture is less likely on HD inputs since the D/A conversion must take place somewhere in the chain.
So I would probalby then stay with my component as I have a HDTV rear projection TV not LCD TV.
Thanks for the information Alon.
