HMDI Passthru?

I’m looking to buy a new home theater setup but am wondering what the deal with the hdmi inputs are. i’ve been hearing things about passthru and decoding, etc… can someone explain the difference between the 2 and what i should look at getting. im not interested in breaking the bank for a super top end system, just something that sounds good is enough for me. currently i’m looking at this one http://reviews.cnet.com/home-theater-systems/onkyo-ht-s5100-black/4507-6740_7-33016441.html?tag=mncol;psum
this is obviously a passthru system… should i pass? currently my receiver is 10 years old but still gets the job done but since i got my plasma tv and about to get a bluray, i’d like to upgrade the rest… thanks for the help!

HDMI passthrough means it has HDMI [I]switching[/I] capability for video. For the audio you’ll need to use a separate optical or digital coax.

Here’s a great site for you to check out…

[ul]
[li]Started as a digital interface.[/li][/ul]

[ul]
[li]Hollywood wanted DRM. So Digital Rights Management Corp LLP came into being.[/li][/ul]

[ul]
[li]Six digital keys were introduced and there had to be a handshake between the sending and receiving unit.[/li][/ul]

[ul]
[li]These are the HDCP codes which have to be in compliance.[/li][/ul]

[ul]
[li]Switchers and Receivers with HDMI inputs were created.[/li][/ul]

[ul]
[li]Paranoid Hollywood thought this would be a haven for pirates.[/li][/ul]

[ul]
[li]Repeater architecture was then created.[/li][/ul]

[ul]
[li]T.V. is a end device which requires a handshake, so you connect a cable box, etc to a T.V with one certification.[/li][/ul]

[ul]
[li]If you connected these devices through a receiver or any device that outputs HDMI, there will have to be constantly repeated handshakes of the digital keys between the sending device and the receiver, otherwise no output to the TV.[/li][/ul]

[B]HDMI Passthrough/Switching[/B] is no repeated handshakes of the HDCP codes.

[ul]
[li]Will only allow video to pass through and requires a separate audio connection.[/li][/ul]

[B]HDMI Repeater[/B] repeats HDCP codes.

[ul]
[li]Allows both video and audio to pass through.[/li][/ul]

:cool::cool:

i see… thanks for the info… seems to make sense. i guess i was under the impression that bd players all decoded audio themselves like more dvd players nowadays can decode dts and whatnot… thanks again
