    The objective in Stage 2 of the project is to implement robust reassembly methods for MPEG-1 video RTP packets.

    You are given the code that (i) buffers the RTP packets, (ii) reassembles their payload into MPEG frames, and (iii) uncompresses the MPEG frames. Unfortunately, the code given assumes that there is no packet loss! Thus, the video is decoded properly when no packet is loss, but if some of the RTP packets are missing, the decoder can produce corrupted and out-of-order frames (due to, for instance, attempt to decode incomplete slices, attempt to decode I-frame as P-frame because of missing picture header, etc.).

    Your task, is to change the reassembler and part of the decoder such that it deals with loss packets properly..

We have not, however, investigated how the sender decides "when to send what". The goal of this assignment is for you to study three papers related to this topic on your own, and write a 4-page report that (a) summarizes their techniques, (b) compares and contrasts the assumptions, goals, issues considered, strengths and weaknesses of each techniques... ]]> Wed Sep 14 12:59:32 GMT-8 2005 Lecture 05: Playout Buffer http://www.comp.nus.edu.sg/~cs5248/schedule.html#05 Adaptive playout mechanisms for packetized audio applications in wide-area networks R.
