Video Streaming Goes Peer-to-Peer

Posted by ryuzaki0 on from the role-reversal dept.

CMU ESM Project writes "Our research group at Carnegie Mellon University has developed a peer to peer streaming video content distribution system called End System Multicast (ESM). The system constructs a self-organizing and adaptive overlay network using the receivers that are tuning into the broadcast events. The system has been used fairly successfully for quite a few events. Now we want test the system with a lot of more users and different user join patterns. We are streaming some very cool video, such as Triumph of the Nerds by Bob Cringely, distinguished lecture by Eric Schmidt, CEO of Google, ACM SIGCOMM conference paper presentation by Dave Clark, and 2002 Sony Legged Robot Soccer Championship. Here is the detailed schedule. So please tune in, enjoy, and help test our system!" The streaming is based on QuickTime; for Linux users, the project page steps through installation of CodeWeaver's CrossOver plug-in.

  3. MPAA raid! by dex22 · · Score: 5, Funny

    In a shock move, the MPAA closed several University research departments this afternoon, in a series of commando-style raids.

    "It's tantamount to theft" said Hilarity Rosen. "People sharing video and film clips like this without paying? It's immoral, unjust and illegal! Luckily, we caught the equivalent of 7,562 illegal viewers. (Well, we caught 17, but they all had VERY fast connections!)

    In other news, Microsoft tommorow will announce a new DSigital Rights system for P2P video, called "PayNow!"

  4. Recompile Kernel? WTF? by brunes69 · · Score: 5, Informative

    You most certainly do *not* have to recompile your kernel to use QT in mplayer. Just build it, download the codecs .zip, and go

    BTW, for debian users, here are the lines to install mplayer (WITH qt6 support):

    echo "deb http://marillat.free.fr/ unstable main" >> /etc/apt/sources.list
    apt-get update
    apt-get install mplayer-686 mencoder-686 qt6codecs w32codecs

    Check out their overlay tree here. It shows how the current peer-to-peer tree of everyone viewing anything at that given point in time. Pretty cool.

  6. Some answers.. by ChrisPalow · · Score: 5, Informative

    Hi all, I work on the project and have been tasked with answering the slashdot communities questions. 1. Bright video: yes the video is too bright just has to do with the video capture we did of this particular video. Other videos look better, check the schedule. 2. Why codeweavers? Mplayer plays Sorenson 1 natively and Sorenson 3 using a binary codec, we can broadcast either. Unforutunately, Mplayer's RTP code doesn't support Sorenson 1/3 streams yet. When looking at the code, I couldn't tell if live.com streaming library didn't support it yet or, more likely, the interface between mplayer and live.com streaming library doesn't support Sorenson 1/3. 3. I'll answer more of how the system works and how its different then bittorrent and other system in a few minutes it's going to take while to type out. In the mean time check out some of our documents. http://www-2.cs.cmu.edu/~ESM-streaming/docs/ESM_Ph aseII.1.pdf is a bried overview. http://www-2.cs.cmu.edu/afs/cs/project/cmcl-yhchu/ www.overlays/ has some of our earlier papers Chris Palow palow@cmu.edu
