ATSC 3.0 Streams Delivered Via Internet

ATSC 3.0 has the ability to specify subchannels that are delivered via internet streaming for devices with internet connections. This means that there is nothing relating to the stream carried in the signal beyond a pointer to the stream along with some parameters that the receiver will need to properly display it. It also means that if the TV signal is lost, or similarly, if the internet stream becomes unavailable, such as due to an internet outage, the stream will terminate.
