Video coding architecture shatters H.264 barrier
High-channel-density low-latency low-power architecture for H.264/MPEG-4 video coding is optimised for surveillance, two-way communications and wireless network applications
The low encode-decode tandem delay and ability to encode and decode 1080p and 720p video at low bit rates makes the WW10K chipset suitable for high-definition videoconferencing and telepresence applications.
"The confluence of HD and broadband is starting to change the perception of video conferencing from elusive to real, and makes possible instant, life-like face-to-face communications across the globe", says Kishan Jainandunsing, Vice President Marketing at WandW Communications.
"Our WW10K H.264 HD codec chipset achieves high-quality video at bit rates that make such communications very practical".

Driver drives LED efficiency
STMicroelectronics has introduced a new white LED driver with specific features for small LCD module backlight and high efficiency white LED power supply for portable applications.
"It provides OEMs with the best solution in the industry for the design of broadband HD video conferencing and telepresence systems".
The H.264 standard produces superior results compared to the older MPEG-2 and MPEG-4 video compression standards.
However, the significantly higher computational complexity of H.264 poses a major challenge in terms of power and footprint.
The WW10K chipset overcomes these challenges by running at 110MHz only, in single chip implementations of the encoder and decoder.
The WW10000BA encoder compresses 1080p or 720p HD video at 2x lower bit rates and 15% better PSNR than MPEG-2 HD encoders.
The WW10001BA decompresses the encoder's bit stream into perfect quality 1080i/p or 720p HD video.
The chipset has an encode-decode tandem delay of less than 35ms or about 1 frame at 30frame/s.
It delivers performance very close to the H.264 Joint Model.
It can handle up to four video inputs simultaneously at different bit rates and resolutions, up to 1920 x 1088.
This makes it possible to design systems that dedicate one camera per participant or group of participants and one display per participant or group of participants, for more immersive and life-like video communications experiences.
The WW10000BA encoder integrates an advanced context-adaptive noise reduction filter.
This not only reduces noise in the source video, but also improves the encoder's compression efficiency significantly depending on the video content.
Accurate constant bit-rate control guarantees video quality versus available channel bandwidth.
Software upgradeability of the chipset makes it easy to apply field upgrades.
The exceptional video quality, low delay, single-chip features and software upgradeability make the WW10K chipset a good choice for HD video conferencing and telepresence systems.
The WW10K H.264 HD codec chipset is currently sampling and will be available in mass production from April 2007 onwards.
A development kit is available with HDMI, component, Y/C and composite video inputs and outputs, PCI and 10/100Base-T Ethernet interfaces.
