The reference design uses the Cavium PureVu™ Video Processor CNW3602 recently acquired from W&W Communications and the Ralink 802.11n MIMO Wireless RT2880 chipset. The PureVu™ Video Processor compresses 1080p quality video to sub 50Mbps which can now be sent with high reliability over a standard WiFi network. This is achieved with perceptual lossless quality and sub-frame latency using the patented Super Low Latency (SLL Technology™) technology. The Ralink 802.11n chipset uses MIMObility™ Technology to support up to 300Mbps with robust connections at extended range.
The reference design provides electronic manufacturers with low, consumer friendly price-point BOM cost while supporting up to full 1080p60 high-definition video streaming with the sub-frame latency required for high-definition wireless gaming applications. The reference design supports up to 7.1 surround sound digital audio, HDMI version 1.3a compliant, with support for Consumer Electronics Control (CEC) functionality and legacy IR blaster control. In addition, High-bandwidth Digital Content Protection Interface Independent Adaptation (HDCP IIA) is supported to meet the requirements of a "Hollywood Approved" wireless transmission technology. Sophisticated rate adaption and packet loss mitigation technology is used to always provide the highest quality video no matter how much wireless interference.
"WiFi has become ubiquitous in the home, the ability to use standard 802.11n as a whole home wireless HD solution is very compelling for TV manufacturers which are already embedding WiFi for internet TV widget applications," said Lars Herlitz General Manager Multi-media Business group Cavium.
"The PureVu™ Video Processor enables ultra low latency and perceptual lossless quality by compressing bit rates to a level which are robustly supported over Ralink's high performance 802.11n WiFi system," said Fred Jann, Vice President of IC Design at Ralink. "Cavium and Ralink have come together to provide a truly viable standards-based wireless HD delivery solution that can be easily embedded into flat panel displays and set top boxes."
WiFi and H.264 Wireless Networking provides a better alternative to proprietary solutions because it is standards based and provides headroom for higher data rates which are required as color depths and frame rates increase. It also allows mitigation technologies to deal with interference and packet loss, as well as co-existing with current 5 GHz networks.
The joint reference design will on display at CES in Ralink's Hilton Las Vegas suite#2169 and Cavium's Hilton Las Vegas suite#2866.
