IPTV is being implemented in different flavors, and part of the reason for the
variation is that while some neighborhoods have very limited Internet speed, others
have been provisioned with very fast fiber optic networks.
Current/Planned IPTV Market Solutions
A couple of years ago I was contacted by a company that developed an HD-IPTV
system. Using this solution, consumers would purchase client STBs for PCs and
stand-alone TVs and receive IPTV content even at 1080p quality, as claimed by the
company.
MatrixStream is the name of that company, founded in 1999 and headquartered in
Vancouver, British Columbia. I included their launched HD 1080p server/client IPTV
products on last year’s annual HDTV Technology report (March 2006, 2006 HDTV
Technology Report).
The interesting part was that the company also offered hardware to enable “anyone”
to become a content distributor via IP from a server to clients in a network.
The company adopted MPEG-4 Part 10/H.264 compression which cuts in half the
stream requirements to transmit via IP the typical HDTV content compressed with
MGEG-2. MatrixStream also implemented techniques to optimize the transport over
the Internet by using proprietary buffering and error-correction techniques that
compensate for Internet bottlenecks.
MatrixStream claims they can transmit a DVD-quality TV signal requiring only 1.5
Mbps and a high-definition 1080p signal requiring only 2.5 Mbps, both within the
limitations of typical DSL and cable-modem hi-speed connections.
If you are interested in further information, please consult the details of companies
implementing the IPTV concept as well as some leaning lessons, the hardware, the
systems, etc. on the Industry Edition report.
