The Future of IP Video and DOCSIS: John Chapman, Part One

- May 14, 2010 - 0 Comments

As multichannel video providers beeline toward an IP-based service infrastructure, they seek capacity, efficiency and QoE, notes John Chapman, Cisco Fellow and Chief Architect, who was interviewed on the floor of The Cable Show, in Los Angeles.

If you’re thinking about how multichannel video shifts to IP transport, from MPEG transport, you’re probably already well-versed in the language of DOCSIS 3.0, and its channel bonding features.

Bonding multiple 6 MHz channels together is the foundation for a multicast, IP version of today’s linear broadcast offerings. In doing so, cable operators dramatically expand their shelf space for multi-screen, multi-format video offerings.

Likewise, by converging video services into one, IP-based pipe, cable operators save in operational and capital expense. And, over time, as more MPEG-based video streams shift into the IP domain, their bandwidth can be recovered and applied to other applications.

A key part of Cisco’s IP video transition strategy is our new 8×8 and 20×20 CMTS line cards, plus new, DOCSIS 3.0-based cable modems for residences. Features include a managed multicast service and RF spanning across an entire CMTS. From there, the video arrives in IP at the home, enters a DOCSIS 3.0-based home gateway, is shifted out on to a home network, and can be dropped off at any IP-enabled device – IP set-top, PC, or personal device.
