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!"
HDMI 1.3 is *not* necessary for sound/1080p video. It's needed for decoding some of the newer audio formats in the receiver, but that's not necessary if your Blu-ray/HD-DVD player has the decoders for those formats, you just decode in the player instead.
