As the producer of webinars and virtual training events for Streaming Media Magazine and Streaming Learning Center, I’m always interested in information that helps me produce more effective events. A recent report from Bluejeans, the Verizon-owned video conference provider, provided several interesting data points. By way of background, the report discussed survey data collected by IDG from 200 respondents in a …

My wife was watching a webinar for CME and there were two physicians with such picture perfect presentation that I just had to snap the image and comment. The list of what these two did right is lengthy and instructive.

Now one of the pool members, Helios Digital, is suing Crackle, Vudu, and Showtime Digital for infringing their DASH patents. As I state in my article …

We’ve been following the story of DASH royalties since MPEG LA first announced the pool back in 2015. Recently, the pool stopped offering licenses, which seemed to cease any assertions of royalties. But as I just wrote about in Streaming Media magazine, one of the pool members, Helios Streaming along with Ideahub, sued Showtime, Vudu, and Crackle. Here’s the rough …

On August 12, 2019, I reported in Streaming Media Magazine that the hugely unpopular MPEG LA DASH Pool might be shutting down. I shared what was purported to be a draft letter from MPEG LA President Larry Horn to pool members which stated the following: “Regrettably, with more than one year’s experience marketing the DASH License according to its revised …
