Re: HDDVD or BluRay DVD?
1. You need to be sure the TV has HDCP which should be in the specs
2. It would be good also if the switch had HDCP
3. They come in 2 x 1 (2 in 1 out ) 3 x 1 ect
If you find one with 4 X 2 it is NOT want you need
# HDMI 1.3v & HDCP Compliant
# Supports DVI devices with an adapter
# Ready to Go
* Includes a 6ft HDMI cable
* Quick and Simple Installation
It is a stock item at Circut City for around 100 dollars
"What is HDCP?
High-Bandwidth Digital Content Protection (HDCP) is a copy protection scheme, developed by Intel which prevents the unauthorized duplication of digital signals that are sent via Digital Visual Interface (DVI) or High Definition Multimedia Interface (HDMI) connections.
HDCP works because it will not allow a transmitting device to send digital information to a receiving device until it has established a secure connection through the use of an authentication and key exchange procedure. The HDCP specification is proprietary so every manufacturer must become a licensee of the company which administer the keys - Digital Content Protection, LLC.
In simple terms, lets take the example of a DVD player which has been connected to an HDTV with an HDMI cable.
When the two devices are turned on, they each send out their "private" identifier and exchange "keys". Only when the transmitting device (in this case the DVD player) is confident the receiving device (the HDTV) is trustworthy, will it begin sending content. If the authentication procedure fails, then an error message is displayed and no content is sent. The details of how the two devices determine each others trustworthiness is of course a trade secret!
If someone tries to connect a recording device that is not licensed between the DVD Player and HDTV, the verification process will fail.
It is expected that the next generation of high definition HD-DVD and Blu-ray Disc players will only output HDTV signals using HDCP. In this case, if the high definition player is connected to a non-HDCP-enabled television set, the player will either output a downsampled 480p signal or nothing at all. "
