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.
