Abstract
Provided is an information processing apparatus that includes circuitry configured to receive a multiplexed image signal and sound signal from another information processing apparatus using a moving picture experts group (MPEG) 2-transport stream (TS); and perform control to cause reduction of data contained in a packetized elementary stream (PES) payload in a PES packet packed in a transport (TS) packet specified by a packet identifier (PID) specifying sound data transmission described in a program map table (PMT) and to extract a presentation time stamp (PTS) contained in a PES header portion of the PES packet after requesting the another information processing apparatus to reduce a sound data amount.
