Advances in compression and wireless bandwidth allow for higher-quality video streaming. We evaluated how MPEG4 Part 2 encoded video performed when streamed across a wired and wireless network. We were interested in the quality of received video and how transmission across the network affected subjective and objective appearance on the client. Our testbed comprised average desktop computers with a stream retrieval program, OpenRTSP, and a server running Darwin Streaming Server, connected using wired and 802.11 wireless Ethernet. Each client was monitored receiving raw video at common bit-rates to note any lost content. Each client saved video locally for comparison with the original using Peak Signal to Noise Ratio and Structural Similarity metrics. Looking strictly at established standards, we found many are incapable of streaming High Definition streams across a wireless network. Wired and 802.11n connections did prove more capable of handling HD video streams.
