Are you ready for CableNet© 2014?  We’re continuing to prep and can’t wait to see you there!  But until then, here’s what’s going on in the world of CableLabs this week:

This Technology Launches Version 2.0 of SwitchStream Alternate Content Delivery Software

This Technology, a provider of dynamic ad insertion and alternate content delivery solutions, announced version 2.0 of its cloud-based alternate content delivery software, now called SwitchStream™. MVPDs use SwitchStream to deliver regionalized content to the right audience, provide alternate content in instances where content has been blacked out, and execute market protection when there are schedule changes.

NAB 2014: All About 4K

This week marked the 2014 edition of the National Association of Broadcasters annual conference and show. The major theme?  Probably 4K TV. Or as some would call it, 4K Ultra, or Ultra-HD, or maybe UHDTV, or possibly even UHDTV1.  Head spinning yet?  Don’t worry, CableLabs’ own Daryl Malas helped to clear up the terminology around 4K in a blog this week.

Cable Ahead of the Upstream Curve

While upstream hasn’t been the hot topic it was a few years ago when P2P sites were gobbling up bandwith, there will come a time in the near future when it’s just as – if not more – important. With DOCSIS 3.1, cable operators will be ahead of the game.

DOCSIS 3.1 includes advanced modulation and agile channel bonding capabilities that increase upstream capacity without expanding the return path bandwidth. Dan Rice, Vice President of Network Technology for CableLabs, points out that DOCSIS 3.1 is backward-compatible with previous iterations of the spec. “Operators ought to understand that they don’t have to do anything to the upstream to use DOCSIS 3.1,” he said. “One of the key underlying principles and objectives was that it should work on existing networks.”

More about the upstream potential of DOCSIS 3.1, and why it’s important, from Carl Weinschenk at Broadband Technology Report.


This week CableLabs held an NDA Vendor meeting.

New certification requirements and guidelines have been posted on the Certification page, as well as fees for European testing and certification.
