Standard ISP Connection Used to Deliver Live Video at Quality
Level Previously Only Available Via High-Bandwidth Dedicated Fiber
or Satellite Link
Montreal, Canada & Boston, MA -- HaiVision Systems Inc., the world’s
leading vendor of high-performance H.264 HD and SD video codecs, and
Zixi LLC, the world’s leading supplier of HD Instant Video Delivery
Network (IVDN) products, today announced the first successful
broadcast of live HD video over the public Internet. |

The broadcasts were transmitted
from the Columbia University Medical Center (CUMC) in New York City
to remote studio facilities in the United States and simultaneously
to several other sites worldwide, where viewers accessed video using
either a Web browser or an Internet-enabled (IP) set-top box. The
real-time HD broadcasts were transmitted over the Internet using
Zixi’s IVDN platform to recover and reorder lost packets in real
time providing instant start, continuous delivery of video to
studio, set-top boxes, and PCs without any sacrifice in video
quality.
The HD (1080i) feeds were transmitted between the CUMC and
convention centers using HaiVision’s acclaimed ultra-low-latency
MAKO-HD H.264 HD codecs. At other locations worldwide, audiences
simultaneously viewed the transmission using software decoders on
standard PCs. The Internet services at both ends were standard
general-purpose ISP connections, with the stream serviced by the
Zixi IVDN platform. In a side-by-side comparison at the receiving
studio, the video quality delivered over the Zixi IVDN was
indistinguishable from the signal received via satellite and
dedicated fiber connections.
“The Zixi platform is revolutionizing public Internet-based network
video communications,” stated Peter Maag, HaiVision vice president.
“Now, through the combination of Zixi’s IVDN and our MAKO-HD codec,
the transport of HD video over the Internet requires only adequate
first- and last-mile bandwidth.”
The broadcast used Zixi’s IVDN platform at the source and receiving
ends to groom the data traffic, recover lost packets, and eliminate
jitter. The latency from source to destination — including the
MAKO-HD’s 70 ms of encode and decode — was under 500 milliseconds,
and the transmission exhibited no re-buffering pauses. The Zixi IVDN
and HaiVision MAKO-HD demonstrated the robustness of the
transmission by continuously streaming video despite as much as 25
percent packet loss on the connection.
"HaiVision’s
MAKO-HD H.264 codec is the premier HD appliance available for
medical, telepresence, and broadcast-style applications,” said
Israel Drori, Zixi’s CEO and founder. “The MAKO-HD’s performance was
outstanding.”
The Zixi broadcast from CUMC was supported by the MAKO-HD’s 6-Mbps
H.264 stream and delivered pristine full-motion 1080i video to
multiple global locations over the public Internet. The MAKO-HD,
which supports up to 1080p30 HD resolution and up to 1280x768
computer resolution at 60 frames per second, contributed only 70
milliseconds of delay to the entire transmission.
