Private data broadcasting using digital TV and MPEG-2 Transport Stream

We present a new system for the transmission of multimedia information within the digital TV channel. The scheme proposed is based on some digital storage media command and control (DSM-CC) functions, while the transport structure used is the MPEG-2 Transport Stream, that is the most widespread platform for new digital television systems. The multimedia information conveyed in such application is structured as in the WWW system, where the text is integrated with images, sounds and animation by the means of the HMTL language.
