Google touts benefits of WebP image format

Google, which controls both ends of the Internet connection for a significant fraction of online activity, has a lot of power over the Internet. A little image-format tweak to one of its Web sites shows just how much.

Few others have expressed much enthusiasm for its WebP image format, an offshoot of the WebM project to promote a royalty-free video codec. Google asserts that its smaller file sizes would unburden networks and help Web pages load faster, but as Mozilla likes to point out when grappling with such matters, adding a new format to the Web means adding a requirement … Read more

HEVC video standard finished; high-end improvements coming

An array of companies have finished work on video compression technology called HEVC or H.265 that promises better video to start with and that paves the way for higher-end extensions next year, they announced today.

The High Efficiency Video Codec supports 4K "UltraHD" video -- and perhaps 8K as well if the video industry can convince buyers that so many pixels are worthwhile. Perhaps more important, given how many people watch video online these days, it doubles video quality for a given network data capacity.

HEVC has the potential to spread very widely indeed. It's the … Read more

Google's new VP9 video technology reaches public view

VP9, the successor to Google's VP8 video compression technology at the center of a techno-political controversy, has made its first appearance outside Google's walls.

Google has built VP9 support into Chrome, though only in an early-stage version of the browser for developers. In another change, it also added support for the new Opus audio compression technology that's got the potential to improve voice communications and music streaming on the Internet.

VP9 and Opus are codecs, technology used to encode streams of data into compressed form then decode them later, enabling efficient use of limited network or storage … Read more

New HEVC video compression wins big over today's standard

A new compression technology represents a significant improvement over today's standard, a new study found. The result could help pave the way for video with at least four times the pixels of today's 1080p standard.

The new compression technology, called HEVC or H.265, is significantly better than today's prevailing standard video codec, called AVC or H.264, researchers from the Ecole Polytechnique Federale de Lausanne in Lausanne, Switzerland, concluded.

"The test results clearly exhibited a substantial improvement in compression performance, as compared to AVC," the researchers said. "As ultra-high definition television has recently … Read more

HEVC, a new weapon in codec wars, to appear in September

A trade show in September will be the coming-out party for video technology called HEVC or H.265, a new arrival in a hotly contested market for the best approach to compression.

HEVC, short for High Efficiency Video Coding, is for encoding and decoding video streams so they can be stored or transmitted more economically than today's dominant H.264, aka AVC or Advanced Video Coding. Specifically, HEVC allies say it can deliver the same quality video as H.264 with half the network bandwidth.

The codec has been in the making for years, but it's now almost … Read more

Qualcomm shows horsepower of next-gen H.265 video

BARCELONA, Spain--H.264 is today's leader when it comes to mainstream video encoding technologies, but it will have to share the stage in 2013 with a successor called H.265 that can squeeze a video into nearly half the file size.

H.264, also known as the Advanced Video Codec (AVC), defines how a video can be compressed for reduced storage requirements and--very importantly given the online video explosion--for streaming across networks. H.265, also called High Efficiency Video Codec (HEVC), uses new techniques to compress video even more.

Qualcomm, a San Diego-based chipmaker that's on the international standards group developing H.265, … Read more
