Over on Mozilla's Future Releases blog, Maire Reavy writes, 'WebRTC is a powerful new tool that enables web app developers to include real-time video calling and data sharing capabilities in their products. While many of us are excited about WebRTC because it will enable several cool gaming applications and improve the performance and availability of video conferencing apps, WebRTC is proving to be a great tool for social apps. Sometimes when you’re chatting with a friend, you just want to click on their name and see and talk with them in real-time. Imagine being able to do that without any glitches or hassles, and then while talking with them, easily share almost anything on your computer or device: vacation photos, memorable videos – or even just a link to a news story you thought they might be interested in – simply by dragging the item into your video chat window.'

Mozilla's Jet Villegas writes, 'Shumway is an experimental web-native runtime implementation of the SWF file format. It is developed as a free and open source project sponsored by Mozilla Research. The project has two main goals: 1. Advance the open web platform to securely process rich media formats that were previously only available in closed and proprietary implementations. 2. Offer a runtime processor for SWF and other rich media formats on platforms for which runtime implementations are not available.'

James Allen writes, "As a result of a chance conversation between a McLaren engineer and a paediatrician, Birmingham Children’s Hospital has been trialling the ECU in a children’s intensive care ward; the idea is that the F1-derived unit can measure all the key signs from the child, sense trends and detect developing problems earlier than the electronics previously used by the NHS. The unit normally measures oil pressures, brake temperatures and the like. Here, a lightly adapted version of the F1 ECU is being used to measure things like heart rate, oxygen levels and blood pressure in an ill child. And, inevitably, it is far more capable than the units currently used in hospitals; it can take a heart cardiogram 125 times a minute, instead of once an hour, for example." Birmingham Children’s Hospital is seeking a further £2 million to continue the trial and extend it across the hospital.

The project, funded out of the Science and Industry Endowment Fund and a year in planning, could provide a ten-fold increase in the speed of point-to-point microwave transmission systems within two years, according to project manager, Dr Jay Guo. Microwave transmission is used to link mobile towers back to a carrier’s network where it is physically difficult or economically unviable to run fibre to the tower. Where current technology has an upper limit of a gigabit per second to multiple towers over backhaul, the government organisation said it could provide the 10 Gbps symmetric speeds over ranges of up to 50 kilometres.'

There two tracks towards royalty-free video currently under consideration by MPEG. The first track is IVC, a new 'standard based on MPEG-1 technology which is believed a safe royalty-free baseline that can be enhanced by additional unencumbered technology described in MPEG-2, JPEG, research publications and innovative technologies which are promised to be subject to royalty-free licenses.' The second proposed track is WebVC, an attempt to get the constrained baseline profile of H.264 licensed under royalty-free terms. Rob Glidden offers an analysis of both proposals. Also of interest is Rob's short history of why royalty-free H.264 failed last time.

They write, 'Tilt is a Firefox extension that lets you visualize any web page DOM tree in 3D. It is being developed by Victor Porof (3D developer responsible with the Firefox extension itself), along with Cedric Vivier (creating a WebGL optimized equivalent to the privileged canvas.drawWindow, see #653656) and Rob Campbell (who first thought about creating a 3D visualization of a webpage). Everything started initially as a Google Summer of Code project, but now, with an enthusiastic team behind it and so many new features and ideas, it has become an active Developer Tools project.' There's also a Tilt blog for development updates.

Google's James Zern writes, 'Transcoding all new video uploads into WebM is an important first step, and we’re also working to transcode our entire video catalog to WebM. Given the massive size of our catalog — nearly 6 years of video is uploaded to YouTube every day — this is quite the undertaking. So far we’ve already transcoded videos that make up 99% of views on the site or nearly 30% of all videos into WebM. We’re focusing first on the most viewed videos on the site, and we’ve made great progress here through our cloud-based video processing infrastructure that maximizes the efficiency of processing and transcoding without stopping. It works like this: at busy upload times, our processing power is dedicated to new uploads, and at less busy times, our cloud will automatically switch some of our processing to encode older videos into WebM. As we continue to transcode the remaining inventory, we’ll keep you posted on our progress.'

They write, 'Nokia has confirmed that it has closed the source code for the Symbian smartphone operating system. It says that despite it describing its new model for Symbian smartphone operating system development as "open and direct" the "open" part did not refer to "open source" but to being "open for business". The "open and direct" model is designed, according to Nokia, to "enable us to continue working with the remaining Japanese OEMs and the relatively small community of platform development collaborators we are already working with".'
theweatherelectric writes: Dr. Silvia Pfeiffer recently gave a Google Tech talk explaining the Web Video Text Track file format. She writes, 'On Wednesday, I gave a talk at Google about WebVTT, the Web Video Text Track file format that is under development at the WHATWG for solving time-aligned text challenges for video. I started by explaining all the features that WebVTT supports for captions and subtitles, mentioned how WebVTT would be used for text audio descriptions and navigation/chapters, and explained how it is included into HTML5 markup, such that the browser provides some default rendering for these purposes. I also mentioned the metadata approach that allows any timed content to be included into cues.' Slides of her talk are also available.
