In his 41-year career, Britt has worked in finance, programming, venture investments, and programming positions. He has spearheaded services such as data and voice, which are now cornerstones of not only Time Warner Cable but of the cable industry as whole, as well as driven the development of multi-screen apps and services, Start Over, Look Back, and cloud-based user interfaces, to name a few.
The main challenge of switching to an IP-based infrastructure is that it doesn’t happen overnight. To make the transition, an operator needs to support two infrastructures for some period of time: a QAM infrastructure that uses MPEG-2 for video compression and a second silo for IP that relies on a mix of MPEG-4 and adaptive bit rate technology.
The latest iteration of DOCSIS, DOCSIS 3.1, will come with significant changes in modulation options that will have important effects on installed and future hybrid fiber coaxial (HFC) networks. Here we’ll be focusing on modulation basics and a discussion of how spectral efficiency (SE) relates to DOCSIS 3.1 performance goals.
There is an ongoing effort amongst cable operators to prevent new, and reduce existing, out-of-spec (OOS) modems. It’s a big deal! Technical performance goals are tied to these numbers and tech ops managers and supervisors require their technicians to not leave the customer premises until the modem meets minimum specifications.
Today’s consumers demand a much more compelling and personalized video user experience than ever before, based on their daily interaction with tablets, smartphones, and an ever-growing number of other sophisticated connected devices. Yet, until recently, delivering this experience on the TV screen was no simple task.
Witbe recently launched version 2.0 of its OTT Robots, which were designed to provide Content Delivery Network (CDN) infrastructure monitoring for CDN operators and service providers that are offering multi-screen and over-the-top (OTT) video services.
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. TDM techniques, tracing back to Baudot’s telegraph multiplex system of 1874, have powered modern telecommunications for a long, long time. But there are signs now that time may be running short for TDM.
In the last two years, we’ve spent a significant amount of time to break down traditional organization silos and to create an environment where a steady cadence of infrastructure and product enhancements and innovative, collaborate thinking are prevalent.
As an industry that delivers important telecommunications services to our customers, we need to anticipate and be prepared to respond to the natural and manmade events that can jeopardize our ability to meet our customers’ needs. Even when we expect the unexpected, the effects on our networks can be extreme.
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.
As of this month, all pre-recorded programming edited for internet distribution must now be close captioned. That's on top of video description content and the requirements of the Commercial Advertisement Loudness Mitigation Act designed to eliminate huge volume spikes in video ads.
For years, 3D’s arduous trek from the friendly confines of theaters to the traditional environs of mainstream living rooms has been stalled by unfilled promises of advancing technologies, by exorbitant costs, and by lack of content. But mostly it’s been about the clunky glasses required to experience 3D.
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.
One year after the Comcast Reference Design Kit (RDK) made its public debut at The Cable Show, the platform has more than lived up to its “service velocity” goal. In short, the RDK went from being a PowerPoint presentation at last year’s Cable Show, to a viable platform that is cutting down on development cycle for not only set-top boxes and gateways, but also applications.
