摘要
Transmitting data in a digital video broadcasting for handheld (DVB-H) receiver comprises a transport stream (TS) demultiplexer adapted to extract internet protocol (IP) datagrams from TS data packets; a packet identifier (PID) filter adapted to extract the TS data packets based on the PIDs of the TS data packets; a Multi Protocol Encapsulation-Forward Error Correction (MPE-FEC) random access memory (RAM) unit operatively connected to the TS demultiplexer; a Reed-Solomon decoder operatively connected to the MPE-FEC RAM unit; an IP to TS encapsulator operatively connected to the MPE-FEC RAM unit; a TS multiplexer operatively connected to each of the PID filter and the IP to TS encapsulator, wherein the TS multiplexer is adapted to combine both DVB-Terrestrial (DVB-T) and DVB-H TS data packets into a single combined TS data packet; and a host interface operatively connected to the TS multiplexer.
