HDMI pass-thru

[gilch]

what does that exactly mean ...

[gearyt]

It means that the signal just passes thru like a piece of wire
no modifications, etc

HDMI pass-thru means that what goes in comes out the back end

Here's an example of HDMI pass-thru for video:

480i ==> 480i

480p ==> 480p

720p ==> 720p

1080i ==> 1080i

1080p ==> 1080p

Here's an example of HDMI upscaling for video:

480i ==> 1080p

480p ==> 1080p

720p ==> 1080p

1080i ==> 1080p

1080p ==> 1080p


On the audio side of things, what I've seen out there is a bit murky. Basically, you need to watch for a lack of audio processing via HDMI. Some HTIB receivers have HDMI passthrough, but they don't process audio via HDMI. That leaves the listener without access to lossless audio tracks via HDMI.

...just remember, not all receivers upscale. And @ 1080p.

Any receiver/HTiB that states "HDMI Pass-thru" will NOT accept audio over HDMI. If you are considering buying one, don't, as you will not be able to listen to HD audio.
