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!"
This first contract between Fox and USVO will not affect the retail market.
Fox is protecting their post-production and pre-release copies of their media.
It is however possible to, and the industry will eventually, mark each download uniquely but that is not what this agreement is about.
Watermarking also works against people who use camcorders in theatres. Apparently one of the biggest sources of video pirating is from theatre projectionists. Some projectionists have the opportunity to set up a screen for optimal recording without being disturbed. In the near future though every copy of a film received by a theatre will be marked with the chain and location information. This is going to force the theatre to protect the film. Again this is not what the Fox / USVO deal is about.
If I was to give the pirates some career advice I would suggest investing in USVO.
