METHODS AND SYSTEMS FOR THE BROADCAST INTERNET, AUDIO OR VIDEO CONTENTS WITHOUT PRIOR AGREEMENT WITH THE SERVICE PROVIDER OR RETURN CHANNEL

摘要

The invention groups a series of methods and systems that simplify management and broadcasting of data encapsulated in the TCP/IP protocol (Internet protocol) on digital data broadcasting using the MPEG-system protocol. By using standard methods to access data networks (Internet), digital audio-video networks and data networks using broadcast-oriented wideband means such as satellite, cable or terrestrial link (standards ETSI EN301192 and TR101202), the invention makes it possible to add the broadcast capacity of said services without prior agreement with or explicit control by the broadcast supplier or the existence of a return channel. The method requires: a) a traffic initiator or generator (A), which sets up conventional Internet connection to an Internet provider (B) that uses a broadcast-oriented system for satellite, cable or terrestrial data broadcasting so as to send to the initiator the contents requested to a server that is adapted for said broadcast service (C); b) a server system (D) responding to the information requests generated by the initiator; the server supplies the data to the gateway of the Internet provider (C), who then broadcasts said data; c) a data extraction system (F) located on the receiver side (G), which extracts the content to be broadcast generated by the initiator, adapting the encapsulation to broadcast the contents using the UDP protocol for the Internet and MPEG-TS for audio-video.
