The skinny: Apple, a member of the MPEG LA H.264 and HEVC patent pools, and staunch supporter of standards (and avoider of open source-codecs) broke ranks and joined the Alliance for Open Media. Give me more: Apple has always deployed standards-based codecs, and Steve Jobs was very negative on Google’s VP8 open-source codec when launched. Alliance for Open Media (AOM) …

One of the more intriguing streaming-related numbers out there is the Netflix ISP Speed Index which topped out at a paltry 3.98 Mbps in the US during December 2017 (Figure 1). According to Netflix, “The Netflix ISP Speed Index lists the average prime-time bitrate for Netflix content streamed to Netflix members during a particular month. For ‘Prime Time’, we calculate the …

On January 5, roughly 27 months after the inception of the Alliance for Open Media (AOM), Apple appeared on the organization’s website as a “founding member.” Like everyone else, we first read the story on CNET, and CNET likely found out when the Alliance simply updated its website. As you probably know, AOM was formed in September 2015, during the height of …

At its June 2017 Worldwide Developer’s Conference, Apple announced support for HEVC playback in HTTP Live Streaming (HLS) delivered to iOS, MacOS, and tvOS end points. 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 …

It’s easy to imagine the deployment of HEVC as a case study in business and technology schools about how not to launch a technology. 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 …

Whether you know it or not, many of the videos that you watch have been configured using video quality metrics. Oh, you disagree? Well, have you have watched Netflix recently?

A short one. Before my trip to Stockholm last week, I sent a list of questions regarding AV1 to David Ronca, Director of Encoding Technologies at Netflix.

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 …
