Let the hive mind of Engadget get that for you.
"I am looking for a device that will stream sound from one source to several recipients. For example, I want to stream sound from my TV or stereo to my phone or MP3 player that has radio and Bluetooth capabilities. I have looked into radio transmitters and they seem like a decent choice, but I can't find one that uses external power (USB or from the plug) and I would want one with a transmit range of around 50 meters. Thanks!"
It would be nice if someone at Imagine Communications can explain how this 2nd look MPEG2 encoder works. I dont think they'll cram channels like CBS, Fox, ESPN, etc on that type of bandwidth. Maybe channels like DiscoveryHD, TBSHD, NatGeoHD, etc will be better suited for this like you've stated in your comment.
