The software is available for download at http://research.nokia.com/research/mobile3D. The implementation has also been showcased at Nokia World 2008 using a modified Nokia N800 device with an integrated auto-stereoscopic display for natural real-time 3D video playback.

OmniVision Technologies, Inc., the largest CMOS image sensor manufacturer today, believes it has found an answer to the sensor shrinkage problem in a novel design that adopts backside illumination (BSI) technology.
Together with Taiwan Semiconductor Manufacturing Corp. (TSMC), OmniVision developed "process tweaks" that allow OmniVision to offer a CMOS sensor with improved image quality while extending its pixel roadmap down to 0.9 micron pixels, according to the company.
OmniVision said that it's ready to start sampling next month an 8-Megapixel product using the new BSI-based sensor design called OmniBSI.
MyPresence is built on technology designed to take advantage of Scalable Video Coding (SVC), which is the key to proving high quality, highly reliable and highly scalable videoconferencing over public and converged IP networks.
Client software encodes SD (up to 30 FPS) and decodes up to HD (up to 30 FPS) on an Intel Core 2 Duo and is currently available from less than £5 per user per week.
MyPresence is powered by Vidyo.

The key activities of MPEGIF are structured via three main working groups:
- Technology & Engineering
- Interoperability & Compliance
- Marketing & Communication
The following topics are specific areas of focus for the MPEGIF throughout 2009 and 2010. New, additional work items will be added as and when required.
- MPEG-4/Scalable Video Coding (SVC)
- Addressable Advertising: extension and adoption of cable Labs SCTE -104 for all multimedia
- Simplifying competitive licensing
- Quality of Experience / Quality of Service metrics
- Royalty free DRM initiatives
- IPTV ecosystem
- Ultra HD (7680x4320)
- MPEG/High-Performance Video Coding (HVC, H.265)
- MPEG-7 / MPEG-21

This is how it works: an algorithm first analyzes the video, subsequently alters different aspects of embedded images or videos (such as the lighting, color and texture), and then attempts to fit the advertising into the physical space of their videos without appearing like a blatant overlay. Watch the video below for some example results.

It uses a dedicated hardware processor to accelerate the creation of H.264 files for Blu-ray, the web, and mobile devices. By using specialized hardware acceleration, jobs are finished with amazing speed and system resources are liberated for other tasks.
Quality and flexibility are ensured through direct integration with professional applications such as Apple Compressor on the Mac and Adobe Media Encoder on the PC. As an added benefit, the Matrox MAX technology allows direct export to higher-quality H.264 Blu-ray compliant files from Compressor.
Matrox CompressHD is the first implementation of Matrox MAX technology in an H.264 accelerator card.
Pierre Larbier, Chief Technology Officer at ATEME, commented: "With our 10-bit 4:2:2 solution, HD content can be compressed to just 30Mbps - compared to 50-60Mbps with current MPEG-2 solutions - offering 2 HD streams over DVB-S2 link rather than just one, and with improved quality. Ironically 10-bit 4:2:2 solution when applied to H.264 offers greater bandwidth efficiency than 8 bits. It is also a 'one technology fits all' situation as it offers native source quality throughout the multi-generation process chain, offering true HD and digital cinema quality even when bandwidth is not constrained."
