== Return channel ==
The MHP [[set-top box]]es 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 ([[Asymmetric Digital Subscriber Line|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 [[Internet Protocol|IP]] with [[Transport Layer Security|TLS]] support.
