Patent ID: 8553723

Claim:
A method for broadcasting a transport stream in a Single Frequency cell of a Multiple Frequency Network comprising multiple Single Frequency Network cells and a plurality of transmitters located in each of the cells, wherein the method comprises: generating, by a central IP encapsulator, a transport stream common to the entire Multiple Frequency Network and which comprises a plurality of elementary streams, each elementary stream being a set of transport stream packets having the same Packet Identifier, at least one of the elementary streams being time-sliced and sent in bursts, and timing information indicating within a burst a time to the beginning of a next burst, transmitting, by the central IP encapsulator, the common transport stream to the transmitters located in each of the cells, receiving, by each of the transmitters located in each of the cells, the common transport stream as an input transport stream, applying, by each of the transmitters located in one cell, a filtering operation to the input transport stream to filter out from the input transport stream part or all of one or more filtered time-sliced elementary streams; modifying, by each of the transmitters located in one cell, the input transport stream so that burst remodelling is carried out, modifying, by each of the transmitters located in said one cell, bursts scheduling of the input transport stream to compensate for removal of the filtered time-sliced elementary streams such that the filtered input transport stream is modified to become a Digital Video Broadcasting—Handheld (DVB-H) compliant output transport stream which is the same both in term of content and timing for all the transmitters located in said one cell; and synchronously transmitting, by each of transmitters located in said one cell, the output transport stream to mobile devices within the cell at substantially the same time with a 100 nanosecond accuracy.
