Abstract
A data transmission device and a data transmission method are adapted to add an RTP time stamp accurately synchronized with the PCR when sequentially transmitting data stored in a recording medium in advance with the MPEG2-TS format or data sequentially formatted to the MPEG2-TS format by means of hardware according to the RTP. With a data transmission device and a data transmission method according to the invention, a TS packet containing header information and real time data, the header information including at least synchronizing time reference information (PCR) necessary for producing a synchronizing signal to be used by the receiving side, is received as input by data reading section, the PCR is extracted from the input TS packet by PCR reading section, the extracted PCR is converted into a time stamp by RTP time stamp computing section, an RTP packet containing header information including the RTP time stamp and TS packets is prepared by RTP packet preparing sectionand the prepared RTP packet is transmitted by data transmitter
