Multi-screen delivery has always been an element of the TV-Everywhere strategy. Over the top content and on demand content can all be prepped ahead of time; linear, live video is a tougher nut to crack. All that video processing has be able to be done in real-time, or close to it. The equipment necessary to prep video – encoders, transcoders, video management platforms – can be almost anywhere in the network, usually depending on where the content is stored, but all capabilities need to be in the headend to distribute over the top, on demand, and linear video.
Economics impel the cable industry to move to IP. IP traffic grows, IP networks expand, and as a consequence IP equipment costs steadily drop, becoming so attractively inexpensive and simple to maintain that cable’s transition to IP is inevitable.
Cable HFC and DOCSIS technology has evolved over the last 15 years, first enabling always-on broadband and today enabling service rates of hundreds of megabits per second. HFC networks will continue to support the best-in-market Gbps speeds delivered to the broadest population of consumers with the best economics.

Four years after Time Warner and Comcast announced their groundbreaking TV Everywhere agreement, multiscreen services are still evolving. Since 2009, customers have shown their willingness to consume video across multiple screens, but stumbling blocks have stood in the way, including content licensing agreements, managing subscribers expectations, and the complexity of dealing with third-party video CDN providers.
The SCTE helps develop standards fundamental to cable networks, covering everything from data & voice communications systems, to energy management, equipment & cabling, network operations, testing & performance, and operations.
Are you ready for 100/40 Gigabit Ethernet? This CED wallchart by VeEx displays the Physical Medium Dependent (PMD) layer, the Physical Coding Sublayer (PCS), the Physical Medium Attachment (PMA) layer, the IEEE 802.3ba standard and the big picture - 100GBase-R.
With video being propagated to Smart TVs, PCs, tablets and smartphones, as well as competition from over-the-top video services from the likes of Netflix, there's no question that cable operators need to transition to IP technology in order to remain competitive.
In the traditional cable world of analog and MPEG-2, ad insertion reaped $4 billion in revenue in 2011, but the next opportunity for cable operators and programmers is inserting ads in a multi-screen environment. On the Internet side, the Interactive Advertising Bureau reported record-breaking Internet ad revenues of $31 billion in 2011.
Challenges remain with multi-screen. Even the most successful multi-screen efforts tend to be implemented in stages.
CED's annual frequency allocations wallchart, with help from the Federal Communications Commission.
Providing better service was the inspiration for content delivery networks, which cache content at multiple points on the edge of the network for more efficient delivery. CDNs were immediately attractive to content aggregators.
The key CCAP objectives are to increase density to reduce cost, space and power; unify the functions of various access network components; and simplify engineering and operations, thereby increasing reliability.
The Society of Cable Telecommunications Engineers is working hard on its Smart Energy Management Initiative (SEMI) to make the cable industry more green.
