And just when you thought that DRM sounded worrying enough, DTCP-IP enters the fray. Not only are providers poised to use DRM to their economic advantage, BUT they're concerned that streaming that protected content across the airwaves will expose it, allowing potential interception by a non-DRM protected device.
So DTCP-IP (Digital Transmission Content Protection over Internet Protocol) will be used as a communications catalyst. It uses 128-bit SSL encryption to ensure that media content streamed out from a Viiv box is protected. It leverages off TCP/IP but it's not restricted to any particular physical medium - wired or wireless is fine.
However, and this is the killer, DTCP-IP reinforces the DRM model. It's not just an innocent bystander. To stream using DTCP-IP, you have to have devices capable of receiving it AND you have to be streaming content written to comply with the DTCP-IP standards. The most popular music store on the internet, iTunes, does not provide DTCP-IP-compliant content.
So, buy yourself a Viiv machine, and you're locked out of iTunes.
