25iHD-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.
