Open Mic - Challenging opportunities for delivering personalized content, advertising

December 31, 2008 7:15 pm | by Joe Matarese, Vice president and general manager of the On Demand Business Unit at Arris Media Communications Systems | Comments

We know we live in an “on-demand” world. From the early days when consumers set their VCRs to record a broadcast program at a specific time, through pay-per-view, hard drive disk recorders and VOD services, there has been a steady growth in consumers’ ability to capture and view content on their own schedule.

CAPITAL CURRENTS: The FCC’s white spaces decision

December 31, 2008 7:10 pm | by Jeffrey Krauss, President of Telecommunications and Technology Policy | Comments

There is another digital video transition underway affecting TV stations, but this one is more complicated than the transition from analog to digital broadcasting.

Reverse path design for DOCSIS 3.0 and beyond - Part 1: The long loop ALC

November 30, 2008 7:45 pm | by Lamar West, system engineering consultant for Cisco Systems Inc. | Comments

The demands of DOCSIS 3.0 and 64-QAM (quadrature amplitude modulation) in the upstream make it necessary to revisit our network design approach. The networks must be approached from an overall perspective that considers cable modem termination system (CMTS), HFC network and subscriber devices (modems and set-top boxes) as part of an overall unified system design.

Traffic woes come to the core

November 30, 2008 7:40 pm | by Brian Santo, Editor | Comments

Service providers of all stripes have been spending money, a lot of money, the last two or three years on backbone and network infrastructure. The issue now is how to monetize it. Telcos are used to rolling out five to 10 services a year, Mock observed. Some competitors try out more than 100 a year.

Video layer quality of service

November 30, 2008 7:35 pm | by Ron Gutman, CTO and co-founder, and Marc Tayer, SVP of marketing and business development, of Imagine Communications Inc. | Comments

Spurred by DirecTV’s 2007 declaration that it will be the world’s first video service provider to reach 100 HD channels, cable operators are moving rapidly to create additional bandwidth, not only to carry dozens more linear HD channels, but also to provide hundreds, and eventually thousands, of HD VOD titles.

IN THE LOOP: One nation, with broadband, for all

November 30, 2008 7:30 pm | by Thomas G. Robinson, Executive Vice President, CBG Communications Inc. | Comments

The FCC certainly senses that change is in the works, knowing that the chairman, and most likely the focus, of the Commission will change with the new Administration. Consequently, they have been scurrying quite ardently to attack a number of controversial issues head-on. Most notably, the new rules to utilize the “white space”...

IN PERSPECTIVE: Shhh…

November 30, 2008 7:25 pm | by Brian Santo, Editor | Comments

Martin has justified nearly every edict and power play at the FCC as ultimately serving the free market, the public interest, or both. I’m just failing to understand a whole mess of concepts here.

MEMORY LANE: A stream runs through it

November 30, 2008 7:20 pm | by Stewart Schley, Media & technology writer, Englewood, Colo. | Comments

At the time, “streaming media” was barely born, and among those who sampled it, it was often maligned. Early streaming-video attempts were based on sequences of eight frames per second, versus the 30 frames specified in the NTSC television standard. The limitation produced halting, flickering progressions relegated to tiny PC screen windows.

Open Mic - Changes: Consolidation comes to China

November 30, 2008 7:15 pm | by Adam S. Tom, Vice President and Co-Founder of RGB Networks | Comments

CAPITAL CURRENTS: The other digital video transition

November 30, 2008 7:10 pm | by Jeffrey Krauss, President of Telecommunications and Technology Policy | Comments

During 2008 and 2009, broadcasters are exchanging their analog 2 GHz electronic newsgathering microwave transmitters for digital ones and converting to a new channel plan. But this transition is way behind schedule. Sprint Nextel is footing the bill because it gets some of the broadcasters’ ENG frequencies.
