You’d think that when my pal Sagee finally got two whitepapers on SVC that he worked on for quite some time published, he would run and tell his friends about it (or at least mention it on his blog). Well, he didn’t – the only thing he did was let his twitter followers know.
I, however, decided I should let my readers know about these whitepapers as both are a good read.
“The SVC Whitepaper”
The first whitepaper to read would be the one explaining more about SVC.
SVC is the latest hype in video coding and it stands for Scalable Video Coding. What does scalability in video coding means, what are the benefits of it, what is the H.264/SVC standard and how would you go about building an SVC-based solution without forgetting the current install base of video conferencing systems – all of these (and more) are part of the information you will be able to find in this whitepaper.
If you want to know SVC better, this is definitely a good starting point for you.
“The Error Resiliency Whitepaper” (aka “The WAN Video Whitepaper”)
The second whitepaper to read would be the one on maintaining high quality video over unmanaged networks – what people would refer as doing video conferencing on the Internet or WAN.
To make a long story short: video conferencing today is highly sensitive to network conditions, and especially to packet loss. It means enterprises usually run video conferencing between their hubs over MPLS instead of the internet directly. The problem? Harder to manage, costs more, constrains video to the boundaries of the organization.
By introducing error resiliency techniques, made possible through SVC, there are means that allow video to overcome packet loss conditions.
This whitepaper will explain the techniques we’ve employed to achieve that goal.
