October 16, 2013 1:53 am | by Yaron Raz, director, Digital Video Solutions, Harmonic | Comments

The main challenge of switching to an IP-based infrastructure is that it doesn’t happen overnight.

In Perspective: Tea Network

October 16, 2013 1:04 am | by Brian Santo | Comments

The beginning of the commercial Internet was notable for an awful lot of stupid stuff, starting with young entrepreneurs who insisted that “Information wants to be free,” and who even more fatuously dismissed people who insisted that a business ought to turn a profit by accusing them of “just not getting it.”

Time division multiplexing is a core enabling technology that has long powered the modern telephone network.

October 15, 2013 11:32 pm | by Jeffrey Krauss, President of Telecommunications and Technology Policy | Comments

With video, you want a continuous stream of video, you don’t want stuttering. So the DASH solution is to break up the program into short segments, and send each segment at a data rate adequate to deliver a continuous, non-stuttering stream. If that means delivering some segments at less than high definition quality, so be it.

September 17, 2013 8:03 pm | by Sophie Percheron, Product marketing manager for live distribution, Ateme | Comments

Ten years after the transition from MPEG-2 to H.264/MPEG-4 AVC, history is about to repeat itself with the arrival of HEVC, also known as H.265, the successor of H.264/MPEG AVC. The standard was approved in January, and just a few months later a live end-toend HEVC content delivery chain was demonstrated for the French Tennis Open event in early June 2013, providing tangible proof that HEVC is on a path toward commercial deployment.
