In Part 1, I was surprised at how little packet loss it took to affect video streaming, but was just as surprised at how hard it was to disturb files played using TCP/IP based protocols. Armed with this knowledge, I set out to see whether success in wireless video streaming was really as hard as I have been making it out to be.

We found in Part 1 that video streams can vary widely in their bandwidth needs and that there are two methods for playing video files across a network. Since I mainly wanted to explore the largest uncontrollable factor in wireless streaming - neighboring WLANs - I decided to use one test file and one play method. I chose an uncompressed VOB (MPEG2) test file with a bandwidth profile shown in Figure 1. The bandwidth was measured using Hoo Technologies' Net Meter.
