Return Channel
The MHP set-top boxes may provide a backchannel for applications that wish to communicate with the outside world, for example a voting or shopping application. Typical upstream backchannels are phone line or broadband Internet connection (ADSL, or 56k in Italy, using a modem included in the set-top box). DVB-RCT (Return Channel Terrestrial) is a wireless technology utilizing the DVB infrastructure. It provides a VHF/UHF Wireless Return Channel back to the broadcaster for Interactive Terrestrial TV. It provides a data-rate of several kbit/s per user, for voting, polls, email, teleshopping, etc. If return channel is present it should provide IP with TLS support.
