iHD-X Open Source
  • Open Source
  • First quarter 2006
  • Looking at various forms of open source
  • Call for participants

26
  • ResearchChannel announced today that its iHDTV
    suite of software will be available as open
    source in first quarter 2006. iHDTV consists of
    software modules that capture, packetize and
    transport high-definition video in various
    formats over Internet protocol (IP) networks,
    with the goal of providing wider access to HD
    content.
  • Developed with the University of Washington,
    iHDTV was first demonstrated at the National
    Association of Broadcasters annual meeting in
    2000. The software suite has since been expanded
    to enable and expedite efficient streaming with
    data at rates of up to 1.5Gb/s, which is
    sufficient to transfer uncompressed 1080i
    high-definition video. The iHDTV code is
    designed to require minimum overhead to achieve
    low latency. Its modular design can easily
    support new devices and flexible modes of
    operation, and the code is highly configurable.
  • Open-sourcing our code will enable us to put
    together a talented group of partners worldwide.
    I expect great advancements in this technology
    with this new, collaborative group,says Michael
    Wellings, director of engineering,
    ResearchChannel.
  • ResearchChannel envisions extensions to the
    current software that will scale the video images
    and tile several images together in a single
    display. These and other enhancements will create
    a package of services that will enable
    high-quality, low-latency, interactive HD
    collaborative environments. These environments
    might include interactions between people, or
    even between people and instruments, such as in
    remote-sensing applications.
