For many, this announcement raised more questions than answers, which we hope to address in this article. By way of background, at Streaming Media West 2017, I co-produced a preconference session on encoding HEVC …

Not only do you have a launch cycle that clearly limited adaption, you also have classic illustrations of two of the major problems related to standard-essential patents, patent holdup, and royalty stacking. Patent holdup refers to the practice …

As a company, Netflix has been very open and gracious about sharing their opinions and test results, both in their excellent blog posts and in many articles in many publications. Netflix’s scale and encoding …

Just back from ten days in Europe where I spoke at Streaming Tech Sweden and met with many streaming producers and encoding vendors. In particular, the vendors expressed dismay at the slow adoption of HEVC, particularly in view of Apple’s decision to include HEVC in HLS. Now that we’ve confirmed that battery life won’t be an issue, adding HEVC to HLS seems like …

I’ve been bullish on AV1 since the start, but I’m starting to think the codec is both farther away and less useful than I initially thought. Here’s what’s happening.
