发明名称 METHOD FOR ENCAPSULATING AUDIOVISUAL CONTENT STREAMS IN MPEG2 PRIVATE SECTIONS, DEVICE FOR ENCAPSULATING AUDIOVISUAL CONTENT IN MPEG2 PRIVATE SECTIONS TO BE MULTIPLEXED IN A MPEG2 TRANSPORT STREAM; INTERACTIVE APPLICATION FOR DIGITAL TV; USER DEVICE; METHOD FOR TRANSMISSION OF AUDIOVISUAL CONTENT AND/OR DATA AND COMMUNICATION PROTOCOL FOR DATA NETWORKS
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.
