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!"
I'm sure that the "per digital sub" requirement by INHD was used as leverage to keep INHD off the satcos and give it a measure of exclusivity, but with INHD2 becoming a thing of the past maybe the cablecos felt it was time to get some more exposure.
