  • Patent number: 8553723
    Abstract: According to a first aspect, the invention proposes a method for processing a transport stream (TS) received as an input transport stream in a processing device (SDR), the transport stream comprising a plurality of elementary streams (ES), each elementary stream (ES) being a set of transport stream packets having the same Packet IDentifier (PID), at least one of these elementary streams being time-sliced so as to be sent in bursts, timing information indicating within a burst the time to the beginning of the next burst, characterized in that it comprises the steps of: applying a filtering operation to the input transport stream so as to filter out from the input transport stream part or all of one or more time-sliced elementary streams; modifying the bursts scheduling of the input transport stream so as to generate a DVB-H compliant output transport stream from the filtered input transport stream.

  • Publication number: 20100031121
    Abstract: According to a first aspect, the invention relates to a method for protection against errors in a transmission system in which a data flow includes a plurality of time-divided base flows to be transmitted as bursts, characterised in that it comprises, for one base flow, calculating a direct inter-burst error correction, and associating the calculated correction with bursts of the flow in order to provide a protection against the total or partial loss of one or more bursts of the flow.
