Can Next-Generation Compression Save Streaming Video From Looming Data Caps?

The Alliance for Open Media formed in September, with heavyweights Amazon.com, Google, Intel, Microsoft, Mozilla Firefox, Cisco, and Netflix as founding members. The group’s plan is to create something like H.265, but without royalties or patent headaches. […] The idea of several tech titans joining forces to make a free compression scheme almost seems too Kumbaya to be true, but keep in mind the companies involved would all benefit even without royalties. For a firm like Microsoft or Google, which ferry heaps of data to and from the cloud, better compression would reap big savings. – Jared Newman, Fast Company

Patent pool wants payment for streaming video

A group of companies — expected to be among them are GE, Technicolor, Dolby, Philips, and Mitsubishi Electric — that hold patents for next generation video compression technology want to change the compensation model for such patents. […] H.265 is the successor to H.264, also known as Advanced Video Coding, widely used for HDTV and Blu-ray Discs. Already used in some devices, H.265 delivers improved video using less data, making it ideal for smartphones, tablets and Net-streamed video. – Mike Snider, USA TODAY

4K Blu-ray discs arriving in 2015 to fight streaming media

The Blu-ray Disc Association is most of the way done defining a version of its optical disc technology that can handle high-resolution 4K imagery, the group said Friday at the IFA electronics trade show here. It will start licensing the technology in the spring or summer of 2015, and the first 4K Blu-ray players should arrive by the holiday-shopping season of that year, said Victor Matsuda, chairman of the Blu-ray Disc Association global promotions committee. […] The new format works on existing Blu-ray discs with 50GB capacity, said Ron Martin, vice president of Panasonic’s Hollywood lab and a member of the Blu-ray Association’s task for for next-generation Blu-ray development. It stores data in a different way, though, moving from the H.264/AVC (Advanced Video Coding) compression technology to the newer H.265/HEVC (High Efficiency Video Coding) successor. HEVC takes more processing to use when encoding videos but compresses them more compactly — or alternatively viewed, lets more pixels be sent across a given amount of data-transfer capacity. – Stephen Shankland,CNET

Streaming innovation will drive 4K uptake

While the larger 4K ecosystem slowly gets its footing, a report from The Diffusion Group (TDG) argues that streaming video will be the spark that lights 4K uptake and use. […] First, US consumer broadband speeds have improved, with average residential wireline connection speeds now topping 10 Mbps. A majority of US broadband households are now at or above access speeds that would enable a single 4K stream to be enjoyed on a living room TV, especially given new codecs.

Second, video streaming technologies have continued to improve, a critical trend that optimises available bandwidth such that larger files can be transported more quickly and efficiently. Though still in its early phases, the next-generation codec HEVC (otherwise known as H.265) has been demonstrated to improve codec efficiencies (i.e., bandwidth savings) of between 25 per cent and 50 per cent compared to today’s state-of-the-art codec, AVC. This is a significant improvement, says [Joel Espelien,TDG], as it represents a gain of 50 per cent, which could mean the difference between needing a 15 Mbps and a 10 Mbps stream to deliver 4K content. – Advanced Television
