Patent ID: 7680396

Claim:
A reproducing system comprising: a reproducing unit configured to reproduce content data stored in a storage medium, and a remote control unit; the reproducing unit comprising: a stream generating unit that generates a stream from the content data stored in the storage medium; an encoded unit that divides the stream into a frame including a frame header, wherein the frame header includes information on the length of the frame; a packet data generating unit configured to generate a communication packet including the frame, append additional information to the frame, and include an additional header including the total data length of the communication packet in the packet, wherein the additional information indicates at least time information corresponding to a reproduction time, and a transmitting unit configured to transmit the communication packet outputted from the packet data generated unit onto a communication path; and the remote control unit comprising: a receiving unit configured to receive the communication packet on the communication path, a data taking-out configured to take out the additional information from the communication packet using the frame length information, and configured to take out the frame, a decoding unit for decoding the frame to produce an audio signal; an output unit configured to externally output the audio signal to a speaker, earphone, or headphone, and a display unit for displaying the reproduction time on the basis of the additional information in real time with the output audio signal after the taking of the additional information out of the communication packet using the frame length information.
