Demo shows off HD video transmission
Analog Devices will demonstrate the first real-time compression and wireless transmission of high-definition video in a consumer application this week at the DisplaySearch HDTV Conference
Analog Devices will demonstrate the first real-time compression and wireless transmission of high-definition (HD) video in a consumer application at the DisplaySearch HDTV Conference on 23rd and 24th August 2005. The combination of ultrawideband (UWB) technology from Pulse-Link, a leading developer of UWB communications systems, and Analog Devices' ADV202, the only real-time HD implementation of the JPEG2000 standard, drastically reduces the visual impact of errors that occur in wireless transmission channels, producing good image quality even in noisy environments.
Whereas other encoder technology has proven expensive and unable to achieve practical real-time HD video compression, JPEG2000 enables high-quality, low-latency wireless HD gaming applications, and high-quality, low-cost wireless HD or SD (standard definition) video distribution in the home.
In addition to the ADV202 compression engine for handling the HD signal, the solution includes Pulse-Link's Continuous Wave (CWave) UWB architecture, which forms the foundation of a 1Gbit/s UWB radio.
CWave differs from other UWB technology in that its signal derives from a narrowband frequency that is modulated to create a UWB signal spectrum.
'Pulse-Link's CWave UWB technology combined with Analog Devices JPEG2000 codec solves many of the challenges associated with implementing QoS for streaming HDTV wirelessly', said John Santhoff, Chief Technology Officer, Pulse-Link.
'Together, these technologies produce a low-latency, highly responsive interactive video gaming experience wirelessly as well as the first lossless wireless alternative to DVI and HDMI'.
'Analog Devices is no stranger to developing high-performance components for advanced TV applications, including those in the ever-expanding HD market', said Bill Bucklen, Product Line Director, High-speed Convertors, Analog Devices.
'We are pleased to team with Pulse-Link to deliver a wireless HD solution that makes wireless distribution of professional quality video available to the consumer electronics market'.
