METHOD AND DEVICE FOR ENCAPSULATING AUDIOVISUAL CONTENT STREAMS INTO MPEG2 PRIVATE SECTIONS, NETWORK COMMUNICATION PROTOCOL FOR IP-BASED LOCAL AREA NETWORKS, INTERACTIVE APPLICATION FOR DIGITAL TELEVISION, USER DEVICE CONTAINING APPLICATIONS, AND METHOD FOR THE TRANSMISSION OF AUDIOVISUAL CONTENT AND DATA

摘要

The present invention relates to a method for the transmission of audiovisual content and/or data to user devices without using digital television tuning resources, in that said content is encapsulated in MPEG2 private sections, subsequently multiplexed and transmitted over a digital television signal. The method uses an interactive application trasmitted in a digital television signal which, when executed in the digital television receiver, extracts the MPEG2 private sections containing the audiovisual content and/or data from the digital television signal and, using a local area network (LAN) connection, forwards this audiovisual content and/or data to other user devices connected to the same local area network (LAN) as the digital television receiver. Also described is a device for the transmission of audiovisual content and/or data encapsulated in the MPEG2 private section.
