Wireless HD signal from my cable box
 
I'm having my family room remodeled and I'm hanging a flat screen above my fireplace. The guy doing my flooring was telling me about this wireless bluetooth setup he saw where you hook up via hdmi cables and transmitter and receiver between set top box and tv, and also do the same with stereo and speakers. Anyone have this going here?

Bluetooth has not enough bandwidth for HDMI. Even Bluetooth 3.0 at 24Mbps is way too slow for HDMI (4.95-10.2 Gbps). There are some custom wireless HDMI TVs from Panasonic and Sony and probably others too.

Definitely not bluetooth, but SONY (and others now I think) do a wireless TV where the only thing you connect to the TV is the power cable. The rest of the unit can be hidden away somewhere in the room and it's that box that you connect your HDMI sources to.

Of course if you hide the box away somewhere, it makes it difficult to use the remote on your SKY+ box etc. (as it would be hidden also). The TV remote uses bluetooth I think (definitely not infra red), so maybe that's what he was thinking of?

Unless Im missing something that you want to do, just connect the cable box to your monitor, dont run it through the PC. Then you can just switch inputs on the monitor from PC, to cable, etc. You can also watch with a PIP screen while working or online. Thats what I do with a Motorola 6200 HD box and a 19" Dell widescreen.

I am confused on this so I am hoping to get clarification. If a device can transfer 24Mbps, the question is whether or not it will have enough bandwidth to transfer a 1080p signal. The math:

Most movies are longer than an hour and a half, but lets use 90 minutes as an example to see if it can handle the large data transfer in a shorter time frame. 90*60 = 5400 seconds at a rate of 24Mbps = 129600 MB in 90 min.

There are 1024 MB in each GB, so this is 126 GB of data that can be transmitted by a BlueTooth 3.0 device in 90 minutes. Most BluRay rips are 8 GB or so. The most I have seen for one movie is 14 GB for a 1080p bluray rip. Even at 14 GB size, a BlueTooth 3.0 device should have the ability to send much more data than what the 1080p signal requires.

The poster above says that BlueTooth is too slow. Is it really?
