Distributed Video Encoding Over A Peer-to-Peer Network
D. R. Hughes, James Walkerdine · Lancaster EPrints (Lancaster University) · 2005
Key Results:An extensible video encoder, which uses a lightweight peer-to-peer grid to leverage the processing power of regular PCs for the purpose of distributing the encoding of highly compressed video, for example MPEG4 and H.264. How does the work advance the state-of-the-art?:Current video encoding technologies tend to focus on single machine solutions, while little or no work on distributed video encoding systems has been undertaken.Current work on distributed computation over peer-to-peer networks primarily focuses upon systems with heavily centralised control [1] [2].The Distributed Video Encoder is a novel example of fully decentralized ad-hoc distributed computation.Motivation (problems addressed): Video encoding is highly processor intensive.While the processing power available on standard PCs is continually increasing, so is the complexity of modern audio/video codecs.The Distributed Video Encoder uses a peer-to-peer network as a substrate for sharing the processing power of regular PCs for the purpose of encoding video.This allows nodes the easy construction of video encoding 'farms' from cheap standard PCs.
