It wouldn’t be an SCTE Cable-Tec Expo without a stellar lineup of technical papers and workshops – even better because each one happens twice, to alleviate trade show schedules.
This year’s program features seven papers and presentations by my engineering colleagues, and a breakfast. Food first: Please join us at 6:30A on Tuesday for a Light Reading breakfast session titled “Monetizing Wi-Fi,” featuring Jared Headley, Senior Director of SP Mobility for Cisco. Here’s a link for more info.
In papers and presentations, here’s what Cisco’s technologists are contributing to the 2013 SCTE Cable-Tec Expo:
- A deep-dive on DOCSIS 3.1 and “downstream convergence layers,” researched and written by John Chapman, SCTE Cable ‘Hall of Famer’, Cisco Fellow and CTO of its Cable Access Business Unit. It’s part of the Pre-conference DOCSIS 3.1 Symposium, which runs all day (10A-4:15P) on Monday, October 21. (In room 309, if you’re going.) John’s a DOCSIS pioneer, and always worth seeing, especially if you harbor any curiosity about how MAC-layer data will get onto the PHY layer – and lots of other 3.1 detail.
- The amount of video distributed over IP is growing fast. John Horrobin focuses on this phenomenon in a session, titled “Implementing End-to-End IP Video Solutions,” drawing from lessons learned in field deployments to compare multicast to unicast and switched techniques. His paper and presentation, titled “Pioneering IP Video in Cable Networks,” also explores current events in the combining network, and how it will evolve in step with CCAP deployments. Gateways with 16 and 24 tuners, that can deliver signals to connected devices over Ethernet, MoCA and Wi-Fi, are also detailed. John’s on at 1:15-2:30 on Monday, 10/21, and again on Thursday from 2:30-3:45.

Part of the tech-buzz at this week’s Cable Show, in Washington, will be about customer premises equipment – set-tops, cable modems, gateways.
Of the CPE buzz, half of it will be about “RDK,” and the other half about how to divvy up what functions live in the house (via the CPE), vs. in the cloud.
That’s our prediction, anyway.
Let’s start with RDK buzz. It stands for Reference Design Kit, and is an industry effort to a) build new cable-specific hardware faster, and b) get new services and apps to the market faster, on that hardware. It was spearheaded last year by Comcast, and is expected to widen to other service providers.
At the Cable Show, we’ll be showcasing Read More »

Three years ago, when I blogged about the Cable Converged Access Platform (CCAP), current events involved whether it would be called “CMAP,” “CESAR,” or something else entirely. (So much clearer in hindsight!)
Last year, when I blogged about CCAP at The Cable Show, current events centered on phasing, and how to prepare plant and infrastructure for the unified QAMs of CCAP — while the gear itself was being architected and built.
For what was Phase 1, Read More »

John Chapman, Engineering Fellow and CTO of Cisco System’s Cable Access Business Unit, is a pioneer in broadband communications, having helped to define and write the original DOCSIS (Data Over Cable Service Specification) spec — which spawned the cable modem marketplace, and, consequently, the broadband explosion we’re living in right now. He’s currently leading the development of the DOCSIS 3.1 specification, which promises substantial throughput and speed gains for residential broadband consumers. In this Q&A, originally posted on the Cable Congress blog “Interview with John Chapman”, he characterizes the highlights of DOCSIS 3.1, why it matters, and current events.
Q. What does DOCSIS 3.1 mean to cable-delivered broadband, as opposed to fiber?
Chapman: Service providers are often under scrutiny in terms of their competitiveness, against fiber-to-the-premise architectures. DOCSIS 3.1 will go a long way in assuaging those misperceptions. It can make that hybrid fiber-coax plant perform as well as fiber, at a fraction of the price of a fiber upgrade. DOCSIS 3.1 is all about getting more bang for the buck – it’s a higher performing, lower cost technology.
Q. What is the biggest change coming, in DOCSIS 3.1? Read More »

…Cisco! As you can imagine, this super-charged our annual trek to Las Vegas for the International CES show, which serves as host for the fanciest-ever black tie event for tech people. (It even had a tech host – David Pogue, himself an Emmy award winning tech columnist for the New York Times. Cool.)
This year marked the 64th time the National Academy of Television Arts & Sciences’ put on its annual Technology & Engineering Emmy Awards, and on the evening of January 10th, I was glad to be amongst my friends and colleagues to accept two, count’em two, Emmys. Read More »
