blu ray player 2 hdmi outputs image
swizoidl
For example, if you wanted to connect a blu-ray player via HDMI to 2 different TVs. Is there a switch that you could use to connect the 2 TVs and easily switch between the two outputs?
Answer
The first two answers are reasonable but need some clarification. The first link is to a 2X1 automatic switch - this means it is designed for 2 Inputs and 1 Output - the opposite of what you need. It may work reversed (single HDMI cables are reversible and bi-directional) but I would not count on it - I could not find where the product info said it does, and I don't know. But at least it is HDCP compliant.
The second two links are for amplified splitters, which will work - except I can't find where they are HDCP compliant, so if you are playing HDCP encoded content, it may not work.
This is what Grumpy was referring to (and he means HDCP - High-bandwidth Digital Content Protection, not DHCP which is Dynamic Host Configuration Protocol, a way of automatic assignment of IP addresses by a router). BUT - HDMI is not "...all about copy-protection". While HDCP IS implemented in HDMI (and DVI and DisplayPort, for example) the Content must be encoded for that HDCP to come into play. HDMI itself does not create the HDCP - merely carries it between source and display IF the content tells it to - see here:

The pertinent sentences are: "HDCP protects content using authentication and encryption. Before sending HDCP-protected data, the transmitting device initiates an authentication process to confirm that the receiver is authorized to receive the data."
Hope this helps clear up confusion - good luck!

How do I get true 5.1 surround sound out of an optical audio cable?
Rob
Before you answer you have to look at my setup first..
Audio/video sources: directv receiver, ps3, seperate Samsung blu ray player.
Sending those signals to tv via hdmi.
Samsung HDTV with 3 hdmi inputs. No hdmi outputs and 1 optical output.
Audio surround sound amplifier: 5.1 channel Panasonic SC-PT760. 1 hdmi output. 1 optical input. NO hdmi input.
Sending audio to this via optical output from tv to optical input to 5.1 receiver.
My surround sound system is a Panasonic sc-pt760. It does not have an hdmi input. So to get my "surround sound" I have hooked up a clear colored Philips Optical cable and the tv sends all audio to my Panasonic surround sound receiver to its optical input. This way I don't have to switch audio inputs. Whatever the tv plays the receiver plays.
My question is how do I get true 5.1 surround sound? Because when I switch the Panasonic surround sound receiver off of Dolby pro logic 2 setting, the rear left and right surround sound speakers don't have any sound suggesting the only reason they had sound was because when Dolby pro logic 2 was on it was converting 2 channel stereo audio to fake 5.1 audio.
So does that mean the tv can't output 5.1 through it's optical output? I don't know how to get true 5.1 to my receiver without a lot of plugging in and unplugging when I'm using that source.
Please only qualified individuals answer. I don't want opinions. I just want somebody who either does this for a living or really knows their stuff. Thanks in advance. :)

I would like to apologize to you for those who keep reminding you the HT in a box are no good.
In tough times like today, not a lot of people could afford to just ditch their HT in a box, and get a new system. Jeeeezz!
Keep in mind that not all TV channels broadcasts in 5.1. Most DVD & Blu-rays do.
That's why the system has that DPL2 is to simulate those not true 5.1 audio signals.
No matter how expensive you pro system, like these folks keep recommending, it will not play true 5.1 audio if the source media was not recorded in 5.1.
Panasonic is a very respectable brand, they would not falsely indicate that your system will play 5.1 audio if it really does not.
