With this bill most houses would be in an IP-TV network using a setup-boxes. So now with this modification each device is uniquely identified and is connected to the cablenetwork and is granted an IP. So now local service providers can send in various command supported by the device and stream video to this device of their choice. They can shut down adevice remotely if (no payment) or even display a custom text message that will scroll on top of a video.
