Mobile video use is exploding and will grow quickly in the years to come. Learn how three companies -- SyncTV, Brightcove, and HBO -- have leaped in to put movies and TV shows in viewers' hands.
I like it quick and easy. I want to reach as many people as I can. And so do you. Which is why more and more of us are creating video apps for iOS and Android mobile devices, as well as for set-top boxes and other connected devices. But what are the secrets to doing it right?
Adaptive streaming technologies like Adobe’s Dynamic Streaming, Microsoft’s Smooth Streaming, and Apple’s HTTP Live Streaming, use multiple encoded files to deliver the optimal viewing experience to video consumers watching on a range of devices, from mobile phone to workstation, via a range of connections, from FIOS to cellular. Though there are differences in implementation, all adaptive technologies switch streams based upon heuristics like CPU utilization or buffer size. That is, if the player detects that buffer levels are too low, it may choose a lower data rate stream to avoid running out of data. If CPU utilization gets too high and frames start dropping, it may request a lower resolution file that’s easier to decode.
While most of the technology that enables stream switching is lodged in the player or streaming server, there’s lots to do on the encoding side to produce streams that switch smoothly. In this article, I’ll outline the key differences between producing for single stream delivery and producing for adaptive streaming.

“Client-aware cloud” is one of the buzzwords that Intel was pushing at IDF 2011, and despite the chipmaker’s ulterior motive for wanting to see synergy (read: “vendor lock-in”) between (x86-powered) cloud clients and (x86-powered) cloud servers, there’s definitely something to larger idea that the cloud should know something about and tailor data for the clients that are connected to it. HTTP proxies like Amazon’s Silk and Opera Mini before it (not that these are the same thing) are part of this client-aware cloud trend, as is Skyfire‘s new Rocket Optimizer 2.0 service.
Skyfire is probably best known as a maker of mobile browsers, and specifically as the company that snuck porn Flash onto the iPad via some clever transcoding and a proprietary browser. But in an echo of Google’s 411 strategy, in which the search giant launched a free directory service in order to gather the voice samples that would later power Android’s voice recognition features, Skyfire has been using the data that it gathers from its 10 million iOS and Android users for a larger R&D project.
That project is Rocket Optimizer, the 2.0 version of which launched on Tuesday. Optimizer is aimed not at consumers but at wireless carriers, where it takes tower- and mobile device-specific data and uses it to transcode and optimize video data on-the-fly to fit users’ screens and network conditions. As with Silk, all of Rocket’s real-time video transcoding and resizing is done in the cloud.
Digital video is in the process of getting another major haircut — a development that promises to provide tremendous relief for bandwidth-constrained mobile networks, as well as for the delivery of ultra-high-definition TV.
The High Efficiency Video Coding specification, also referred to as H.265, will be even more efficient than H.264 MPEG-4 Advanced Video Coding. HEVC-based commercial products could arrive starting in 2013.
According to industry experts, HEVC could shave off 25% to 50% of the bits needed to deliver video that looks as good as H.264.
“It seems like every decade we come out with a better compression standard,” said Sam Blackman, CEO of video-processing systems vendor Elemental Technologies.
HEVC is being designed to take advantage of increases in processing power in video encoders and devices. The developers of H.264 had elements they wanted to include, “but the computational costs were considered too high 10 years ago,” Blackman said. “You’ve also had research over that time to improve the standard for the next time.”
Social media continues to influence how consumers interact with brands and share content every day. Increasingly, TV viewers leverage social media as a platform to talk about and engage with TV content.
UltraViolet is Hollywood's first real effort at breaking the Apple stranglehold. The idea is that by implementing a digital rights locker, the studios involved will enable viewers to purchase a piece of content once and watch it on any device.
