Abstract:
1. A digital content reproducing and storing apparatus configured to perform a storing operation while receiving TS packet constituting digital content and configured to perform a reproducing operation through a PES (Packetized Elementary Stream) obtained by demultiplexing the received TS packet or a read-out TS packet stored therein, the digital content reproducing and storing apparatus comprising: a demultiplexer to demultiplex the received TS packet to obtain the PES; a control circuit to sequentially buffer the received TS packet in a buffer, and stores a group of buffered TS packets for a predetermined time in storage while adding time information contained in the obtained PES to the group; and a reproducer which specifies a TS packet based on the time information corresponding to a designated prior time and perform the reproducing operation based on the specified TS packet, wherein when storing the group of the buffered TS packets while adding the time information to the group, the control circuit: obtains a rearmost storage pointer in the buffer at storing a previous group of TS packets; obtains first time information for a TS packet which has already been stored in the storage, from a PES obtained by the demultiplexer; obtains second time information from a newest PES obtained by the demultiplexer; determines whether a time difference between the first time information and the second time information exceeds the predetermined time; and stores a group of TS packets buffered from the rearmost storage pointer up to a TS packet corresponding to the newest PES while adding time information if it is determined that a time difference exceeds the predetermined time.
