Abstract:
In a next generation broadcast architecture, a broadcast gateway may send segments of a data file to a broadcast transmission system and to a server. The broadcast transmission system wirelessly transmits the segments to a user equipment (UE) device. When the UE device fails to decode a segment, it sends a request for re-transmission of the segment to the server via an IP network. The server re-transmits the requested segment to the UE device via the IP network. Furthermore, the gateway may receive one or more IP data flows (e.g., video streams) having variable bit rate. The gateway may apply dynamically-variable coding to the IP data flows so that the resulting coded IP data flows have an aggregate bit rate that matches a constant physical transport rate of the broadcast transmission system.

Claim (Index 13):
A gateway for applying channel encoding with dynamically-variable coding rate to one or more data streams to be transmitted by a broadcast transmission system, wherein at least one of the one or more data streams is a variable rate stream, wherein the broadcast transmission system is configured to transmit data with a constant physical transport rate, the gateway comprising:\n a channel encoding unit configured to applying channel coding with fixed coding rate to the one or more data streams to obtain respectively one or more coded streams; a rate matching unit (RMU) configured to modify the one or more coded streams in order to obtain one or more respective modified streams, wherein the RMU is configured to modify the one or more coded streams by injecting null values into the one or more coded streams and/or by puncturing selected values of the one or more coded streams; a control unit configured to:\n receive information indicating a number of information bits per unit time in each of the one or more data streams; and \n vary the number of injected null values per unit time and/or the number of punctured values per unit time so that an aggregate bitrate of the one or more modified streams matches the constant physical transport rate, wherein said varying is performed based on the one or more numbers of information bits per unit time in the one or more respective data streams.
