lab7 MyEalvid-NT

understanding the improved version of MyEalvid.

1. we are going to find the decodable frame rate, packet loss rate, packet delay and packet jitter.

internet - wireless AP - video recv.
/------------packets lost---------/

2. ns2 simualtion


3.
use et.exe to evaluate sd rd .st


total_frame=89998
decodable_frame=82217
and I-frame, P-frame, B-frame

4.
find average and maximum delay



5. plot the time delay of packet sequence



6. plot the frame delay



7 plot the packet jitter



8. plot the frame jitter
