Abstract (en)

[origin: WO2017216597A1] The present invention proposes a method and a device for deterministic re- multiplexing of transport streams, such as digital television signals primarily intended to be broadcast over Single Frequency Networks. DTT frame delimiters are inserted in streams by head-ends. The resulting streams are received by the transmitters that operate DTT frame after DTT frame. TS packets for a current DTT frame are filtered from the input streams and stored. Once all the TS packets for the current DTT frame have been retrieved, they can be inserted in the output remuxed stream, in the stream portion corresponding to that DTT frame, according to timestamping. The applied deterministic insertion scheme is based on a request management process allowing to smooth packet insertion within the DTT frame, in order to insert a maximum number of retrieved TS packets in the output stream while fulfilling their timing constraints.
