Aspects of a method and system for processing audio and video transport may comprise synchronizing streams with associated program content based on 24-bit presentation time stamps (PTSs) and 32-bit system clock samples (SCSs) field without using decoding time stamps (DTSs). A PTS field may be provided as part of a packetized elementary stream (PES) packet syntax. An SCS field may be provided as part of a transport stream (TS) syntax. A system clock (STC) may be determined from received SCS values. Video and/or audio data may be decoded as soon as they arrive and when there is at least one display and/or presentation frame buffer available. The video and/or audio data may be presented for display and/or play based on a comparison of the PTS and STC values. When a frame does not have an associated PTS, a PTS extrapolation operation may generate an extrapolated PTS value from previously received PTSs.
