Dispelling the Myths of HD Video Conferencing – Part 2 of 7

Myth 2: High definition video communications isn’t possible over the public Internet

Fact: This is simply not true. On a daily basis, you can run 768Kbps HD video over the public Internet, whether it’s across cities or across continents.


Depending on the time of day and other factors (ex. a large amount of network users at the same time utilizing an excess of bandwidth,) some packet loss impacting picture quality might occur. HD video communications systems do have solutions for packet loss recovery, and Quality of Service (QoS) networks are available for mission critical applications that can’t be subject to this problem.

For instance, LifeSize’s Adaptive Motion Control (AMC) combines standards-based and proprietary tools to minimize video degradation from packet loss. AMC allows video systems to adapt to ever-changing network conditions, auto-negotiating in real time to consistently ensure a fluid, lifelike experience, handling natural motion in conversation (at 30 or 60 frames per second.) AMC applies industry standard techniques such as bitrate downspeeding, packet marking, and forward error correction (FEC) to overcome network congestion and deliver an unparalleled, collaborative experience over video.
