Hi John, I agree with the other replies in terms of using existing equipment and the unreliability of wireless. I have delved into this area quite a lot in the past and asked similar questions at a IPTV conference a year and a half a go. There are products such as Slingbox around that convert a video stream into signal that is relayed over IP. You then need a device capable of intercepting the IP stream and then decoding the signal. Other options include using Xbox 360/PS3 or using a modded original Xbox. The system we had in our flat allowed us to leave a server on and have the Xbox request a stream and since it worked over cable it was fine. However for HD signal you will need a media box with the ability to deal with the data bandwidth and the original Xbox is limited and so you will get frame skipping. I use Tversity but there are other programmes out there that will do similar things. TVersity will allow you to do the second thing too as it allows streams to be set up but requires a fast PC if you are going to be encoding the signal at a rate that is suitable for wireless. An h.264 stream requires a lot of bandwidth and so you may be better suited using a power line network adapter for 200 pounds or so. That will allow 200mbps connections depending on the product and allows a no wire/ high bandwidth system that is more robust than current b/g 2.4ghz signals. Or you could work off an A band signal by investing in new equipment to move to a less crowded spectrum. Using Tversity, the DLink and a powerline adapter you should be sorted.
