Hdmi Connections Over Long Distance
HDMI Connections over Long Distance
Background:
Upgrades from CRT based to HDTV have been rapid and as HDTV technology continues to mature, consumers will begin to update the 2nd and even 3rd TV sets to HDTV. HDMI is the de-facto standard in connecting HD source to the HDTV. In some special applications, especially with projectors, the cable lengths can exceed 50ft and require specialized connectivity solutions. We will present some solutions for distributing HDMI over long distances.
Possible Solutions :
HDMI Extenders:
In applications where HDMI cabling is readily available and easily installed, a convenient solution for extending HDMI reach is to install a HDMI Extender at the end of the HDMI cable. Most HDMI extenders work by adaptive equalization and compensates for frequency varying signal attenuations, and timing skew. For most applications where connection lengths are between 35-75ft, using HDMI Extender is recommend
HDMI over Ethernet:
It is possible to distribute HDMI over a pair of standard Ethernet cables by using HDMI to Ethernet converters. The HDMI Ethernet converter enables transmission of 1080P HD HDMI digital video and audio over a pair of standard Ethernet CAT5/6 cables.
Using HDMI over Ethernet Transceiver allows installers to use standard CAT 5/ 6 cables for ease of installation.
Advantages of using HDMI over Ethernet:
-Ethernet cables and connectors are easily field terminated thus allowing installers to easily install the proper length cable needed for ultimate flexibility and eliminate logistics problems of having custom length HDMI cables. No need top pre-measure and customer order cables.
-Allows transmission of 300ft (1080i) and 150ft (1080p) over Ethernet cables. CAT 6 cable is recommended for 1080P and best performance
Conclusion:
As the HDTV market continues to mature, consumers will need to be educated on the HDTV video connections available. We have presented some possible solutions for distributing HDMI over long cable runs, so the consumer can make intelligent choices in selecting the HDTV video connections.

Would 1080p movies work on a 1080i Projector?
I recently found out that a HDMI cable came with my Xbox 360 Elite. My TV isn't HD but my projector is, but it goes up to 1080i only. So I was wondering, if I burned some 1080p movies onto a DVD-R/DVD+R would they work on my projector which only goes to 1080i. Also I am going to run these movies from my 360, to my projector.
So to summarize, would 1080p movies burned onto a DVD-R/+R still have their HD quality and would they run on my 1080i projector?
I can't speak to how well you will succeed with HD movies burned to DVDs for playing on an XBox, BUT assuming you can record and play them without having compressed them so much they are no longer high quality HD video, your projector will display them. That said, depending on whether your projector accepts a 1080p signal or not (many sub-1080p projectors won't), you might have to set the ouput of your XBox to 720p or 1080i. Which will look better will depend on the relative quality of the scaler/video processor in the XBox and the projector.
A bit of discussion.
Your 1080i projector has a native resolution of 1366x768 or less. In reality it is at best a 720p projector (and may be even less). You need to consider the "native" resolution ... which is the actual number of pixels that the projector can display. While it may "go up to 1080i", this is the highest resolution input signal it can process (via the internal video processor chip), NOT the resolution it actually displays. That said, the image will almost certainly be better than on an SD television.
Given your objective 1080p is probably not the best resolution to aim for in burning movies to DVD. First of all 1080p will be wasted since you definitely can't display that resolution, so you will have to really compress the 1080p video to fit it on the disk, yet can't benefit. You would be better to down scale to 720p and use less compression.
Good luck.
