Two days down and my colleague tells me we’re now exactly 54.8% of the way through the show.  Being at an event full of engineers I shouldn’t be surprised that someone’s actually developed an app for that.  Despite tired legs and croaking voice, there’s a buzz about NAB Show that makes me look forward to day three.  The speed with which conversations on concepts turn into new technologies mean an event like NAB Show is always interesting.

Our main theme for tomorrow is SSAI support for MPEG-DASH and CMAF – two areas that have developed significantly in the last twelve months.

SSAI for MPEG-DASH

There’s been a lot of talk in the industry about MPEG-DASH.  Yospace was the first vendor to announce server-side ad insertion (SSAI) support for MPEG-DASH and is one of the only vendors today that has live customer services using it, so we’re in a strong position to talk from a point of experience.

The ecosystem for supporting MPEG-DASH is still relatively immature in terms of players, encoders and packagers.  Behind this is the fact that the specification for MPEG-DASH doesn’t specify exactly how an MPD should be expressed to support SSAI. You can read more in this blog post.

CMAF

At 3.30pm our Founder & CTO David Springall will be presenting on the Bitmovin booth. He’ll be discussing our integration points as well as server-side ad insertion for CMAF.
