The standard ABNT NBR 15607-1:2008 - Digital terrestrial television – Interactivity channel establishes the ways in which a receiver device can send information back to the broadcaster through different communication mechanisms. The transmission of common broadcasting content will be done through the air through the main programming feed, while a more customized use of content can be sent through the interactive channel.

Contents

The standard was written by telecommunications and television experts from many countries with their works coordinated by the SBTVD Forum and cover in detail all the aspects of video and audio coding that applies to SBTVD.

The transmission of common broadcasting content will be done through the air through the main programming feed, while a more cutomized use of content can be sent through the interactive channel.

Document technical overview

Brazilian proposal for the interactivity channel is focused on flexibility and is based on TCP/IP protocol. Receiver shall have an USB interface for an external Modem connection. This is adequate to comply with an existing telecomm infrastructure of multiple technologies and is also open for future innovations.

Also, the standard allows for many different possible ways of connecting a receiver device to a network, and use it as an interactivity channel. Future technologies in communications can be easily integrated in the proposed system.
