Problems solved by technology

[0006] Due to this single source feed, terrestrial repeaters become unable to perform their functions in the event of a problem between the content source and the repeater
In any event, most terrestrial repeaters only forward received content intact, and thus cannot insert and / or delete content locally, e.g. in order to broadcast different content depending on the region in which they are located

Embodiment Construction

[0032] The object of the invention is to be able to feed terrestrial repeaters by means of three different networks (a first satellite transmission network, a second terrestrial and / or satellite transmission network and a third terrestrial transmission network).

[0033] It is assumed below as a non-limiting example that the first satellite transmission network (R1) is a broadcast network (for example of the DVB-S / S2 type) and that the second transmission network (R2) is a terrestrial wireless broadcast network (for example of the MPEG-TS type) , and the third terrestrial transmission network (R3) is an IP (Internet Protocol) fixed transmission network (eg of Ethernet type).

[0034] However, the invention is not limited to these examples of transport networks. Indeed, they may also include transmission networks allowing two-way communication, and possibly wireless (or hertz-type), satellite or terrestrial broadcasting networks allowing (at least) one-way communication network...

Abstract

A terrestrial repeater (RT) comprises i) interface means (Ml) in charge of receiving a first data stream originating from a first transmission network of satellite type (R1), a second data stream originating from a second transmission network (R2), and a third data stream originating from a third transmission network of terrestrial type (R3), and of transforming these received streams into data packets, ii) first processing means (MT1) in charge of selecting part at least of the data packets of one at least of the first, second and third streams received and of processing each stream part selected so as to place the data packets that it comprises in a chosen broadcasting format, and iii) second processing means (MT2) in charge of combining together the stream parts selected and processed so as to constitute a set of packets to be broadcast, then of converting this set into a radiofrequency signal, and of amplifying this radiofrequency signal with a view to the broadcasting thereof using waves to at least one radio communication terminal (UE).

Description

technical field [0001] The present invention relates to communication systems and in particular to the broadcasting of content via terrestrial repeaters to wireless communication terminals by means of such systems. Background technique [0002] In this context, "communication system" means a system consisting of at least part of a network of satellites, possibly geostationary satellites, including at least one broadcasting satellite, and at least part of a network of terrestrial repeaters The repeater is installed at a known location and possibly coupled to (or installed at) a base station of a radio access network of the wireless communication network. Such satellite and terrestrial repeaters are notably responsible for broadcasting content to wireless communication terminals. Such broadcasting may be via satellite and terrestrial repeaters simultaneously (feeds are received from one or more satellites, which may be different from the satellite providing the feed to wirele...
