The University of Essex and the Poznan Supercomputing and Networking Center have plumped for SYX-JP4K, the new JPEG 2000 4K streaming system, developed by intoPIX. At the end of last year, during the official opening of the Essex Ultra High Definition facility, the new intoPIX 4K Streaming system was demonstrated, achieving a complete encoding-streaming-decoding chain for 4K material between the Poznan Supercomputing and Networking Center to the Essex facility, in real time. This connection was achieved via dedicated high speed links through national and European research network infrastructures.
intoPIX's future proof JPEG 2000 technology is said to fit perfectly with the ever-increasing demand of UHD and other emerging media formats that go beyond HD. "In the near future, broadcasters will be able to shoot and transmit real time in UHD resolutions. By using JPEG2000 compression, broadcast facilities will benefit from an efficient scalability, specially well-suited for handling high resolution material. It is an intrinsic feature of JPEG 2000 to be capable to extract HD from an UHD stream in real time, without the need for transcoding, cropping, downscaling or any other additional processing," comments Gael Rouvroy, CTO of intoPIX.
The company has already announced new versions of the SYX-JP4K system for 2010, capable of 8K encoding, streaming and decoding in real-time.

Sirius, says Global Display Solutions, GDS, finally gives to outdoor communication the wow factor digital out of home has been always looking for. The new, high brightness products are said to be ideal for digital signage and public information display applications.
"The technology behind these stunning images and this unmatched level of picture detail in full sunlight outdoor environments is all but obvious", says CTO Andrea Ongaro. "Researches, testings and investments around this project have been massive but now GDS can offer to the market very high performances in outdoor environments as well as high reliability and improved ROI. With nearly 15 years of experience, this product range confirms GDS being at the forefront of outdoor display technology."
New GDS ultra high bright technology, incorporated in its UHB products, integrates LED backlighting, cooling and G-Bond optical enhancement. The LED backlight, designed by GDS, can reach 4000cd/m2 by using high efficiency white power LEDs. The LED backlight, says GDS, also enables a power saving of nearly 40% if compared with displays with CCFL backlighting.
By using traditional LED dimming instead of local LED dimming, GDS says it reduces the risk of burning effects on the screen and improves the life of the system. The contrast will be as good as that of systems with local dimming as the monitor will be used in high ambient light environments and not in dark rooms. The LEDs are also a green alternative to CCFL lamps as they are mercury-free.
The new UHB range has a twin cooling system that optimally maintains temperature of the panel, LED backlight and electronics. This improves the MTBF of the whole display and the efficiency of all internal components. The twin cooling system does not use air conditioning and hence is said to reduce power consumption whilst optimising component count. The twin cooling system prevents the display from reaching the clearing point and from generating moisture in front of the panel, making the entire system able to work even in direct sunlight.
GDS’s G-Bond improves image contrast in high brightness environments and strengthens the TFT panel by bonding an anti-vandal glass of 6~8mm thickness. At the same time G-Bond protects the panel from mechanical and thermal stresses from air cooling streams that can be at speeds of 6m/s to cool a 1m2 panel.
"GDS proprietary technologies,” concludes Andrea Ongaro, “allow GDS to use different panels to accommodate customer requests. This flexibility gives to the customer a wide range of options of features. The new range, will be initially be available in sizes of 65 and 46in.”
