Chrome 27, making its way through the development pipeline, is helping to advance the fortunes of a new audio compression technology called Opus.

Opus is what's called a codec -- a technology to encode and decode streams of information, in this case audio. Technically, it's actually two codecs in one, an approach that lets it span a range of uses from Internet telephony on slow networks to streaming high-quality music on fast networks.

One of its chief virtues is low latency: there's not a long wait for audio to be encoded or decoded, something that's not … Read more

Developers these days are obsessed with mobile apps, but a startup called Chorus.im hopes the Web will be its entree into a new instant-messaging market.

The Mountain View, Calif.-based company is using various Web standards to try to build an IM service that works in people's browsers. The new generation of Web technologies for Web apps is often called HTML5. Although the company offers mobile apps for iOS and Android, too, the Web approach can be convenient since people can launch it just by pointing a browser at a Web site.

And indeed, that's how it … Read more

The nascent WebRTC standard for video communications on the Web has become a technology battleground pitting Google against Nokia.

The reason for a war not just of words but also of actions is a lowly technology called a codec, which compresses video for efficient networking and compact storage. Google wants the Net to embrace its royalty-free, open-source VP8 codec, but Nokia is trying to quash VP8 by refusing to license patents it says are required to use it.

Google, meanwhile, has come to the aid of Android phone maker HTC in a Nokia patent-infringement case that involves VP8.

Why the … Read more

A Google patent-licensing deal two weeks ago dramatically improved the fortunes of its VP8 video technology, but Nokia has added a barricade to what has already been an arduous road to adoption.

VP8 is a codec -- technology to encode and decode video or audio data for compact storage and efficient network streaming. Despite passionate debates about VP8 vs. the incumbent codec, H.264, most people need never care about video codecs.

But as video becomes ever more deeply embedded in the Net -- TV entertainment, chatting with friends, videoconferences for business, online schooling for children -- the video codec … Read more

Taking a page from Opera and Amazon playbooks, then writing on it some more, Google is using its own servers to speed up page loading on its mobile version of Chrome.

The feature, called proxy browsing, is enabled in the Chrome 26 beta for Android, though it must be manually activated through the chrome://flags interface by selecting "Enable Data Compression Proxy." With proxy browsing, a server with a fast Internet connection and more processing horsepower than a mobile device loads the Web page on behalf of that mobile device.

The chief advantage of the approach is that … Read more

BARCELONA, Spain--Mozilla, Ericsson, and AT&T announced today they're demonstrating technology to place Internet-based voice and video calls that bridge traditional telephone services and the Web.

The demonstration, at Mobile World Congress here, uses the nascent WebRTC (Web Real-Time Communications) standard to set up browser-based communications between different devices.

The "proof of concept" links a Web app with a person's existing phone number and "shows how consumers can easily take and receive video calls from their mobile phones or desktop browser using WebRTC or share their Web experiences with friends or family who might … Read more

Mozilla, which bowed to the market power of the H.264 video compression technology last year, now has built support for the patent-encumbered standard into the Nightly version of Firefox on Windows 7.

Mozilla can't actually ship H.264 in its open-source product because of the patent licensing requirements, so it decided instead to adapt Firefox to draw on H.264 support built into newer operating systems. The first step is done -- if not fully tested and debugged -- on Windows 7, according to a Mozilla blog post today.

Mozilla had thrown its weight behind VP8, a royalty-free … Read more

Google's newest interactive browser "experiment" transports you from your desk to Oz, highlighting cutting-edge browser tech along the way.

Created in conjunction with Disney and the production company Unit9 to help promote the upcoming movie, "Oz the Great and Powerful," the experiment leverages the latest in Web standards to create a browser-based experiment that previously could have been completed only with Adobe Flash.

In the experiment, called Find Your Way to Oz, you can compose music, goof around with a photo booth, and make a short movie with a zoetrope. If you survive the tornado … Read more

The days of needing an app, add-on, or extension to make video calls in your browser are numbered. Google and Mozilla, the respective makers of Chrome and Firefox, just demonstrated a new development in HTML5's WebRTC protocol that lets people talk to each other using two different browsers and no third-party apps.

Currently only available in Chrome 25 beta and Firefox Nightly, the change in WebRTC comes thanks to the development work of several groups. These include members of the World Wide Web Consortium (W3C) and Internet Engineering Task Force (IETF), as well as engineers at Google and Mozilla. … Read more
