ViXS Introduces World's First Low cost, Video Focused 802.11 a/b/g Integrated Circuit and Reference Design
Matrix II First Single-Chip Processor to Simultaneously Deliver Dual Stream HD Video Over Standard 802.11 a/b/g. WaveTV Highly Integrated Reference Design Allows OEMs to Quickly and Cost Effectively Develop High Performance Wireless Video Systems
Toronto, CanadaViXS Systems introduced Matrix II, an 802.11 a/b/g WLAN chipset specifically designed for wireless audio/video distribution. Matrix II is the first WLAN processor to wirelessly distribute two HDTV (19-24 Mbps each) video streams from a single IC. It is the only wireless chip that utilizes multiple antenna Maximum Ratio for MIMO 802.11 pre-802.11n performance gains while maintaining the cost advantages of being a fully standards compliant 802.11a/b/g IC. Designed especially for consumer video and display products, Matrix II provides over 40 Mb/s useable bandwidth with a range of 100 feet through 3 walls, or a total raw throughput of 124Mb/s.
Building on these accomplishments, ViXS has introduced the WaveTV and Mini PCI reference platforms to assist manufacturers in developing next generation wireless media centers, flat panel TVs, Personal Video Recorders (PVRs), DVD players/recorders, and media center PCs. By integrating these platforms, OEMs and ODMs can offer new products capable of delivering wireless HDTV and SDTV video throughout even the largest home without the need for proprietary or closed-loop technologies.
The WaveTV reference platform's low component count and small form factor represent the industry's lowest cost and highest performance wireless television reference platform. It allows consumer electronic OEMs and ODMs to more easily, quickly and cost-effectively develop next generation wireless flat panel televisions and other wireless video devices.
The WaveTV reference design includes the complete set of capabilities and features necessary for a high performance wireless TV solution, including: single or dual client support; 802.11a/b/g compliant, 802.11 e/h/i/j extension support; single or dual analog TV tuner(s); S-Video, composite, component video inputs/outputs; and stereo L/R inputs/outputs.
Matrix II enables manufacturers to minimize production costs and enhance product differentiation by integrating a single chip to increase performance and interoperability with any 802.11-enabled device. It provides transport stream (TS) interfaces for a seamless connection to off-the-shelf MPEG decoders and MPEG encoders. In addition, Matrix II's max-ratio receive diversity, enhanced error correction, and enhanced signal detection are used to increase the overall performance of the wireless video network. When combined with ViXS' XCode II video network processor and ViXS VQoS technology, Matrix II provides a full end-to-end wireless video solution.
ViXS' VQoS technology enables broadcast-quality frame rates across hostile wireless networks. It dynamically governs the bit rate of video streams, ensuring that the total video bit rate is less than, or equal to, the bandwidth constraints of the wireless network..
To enhance quality of service, Matrix II is only wireless 802.11a/b/g chip that features audio/video clock synchronization to eliminate frame drops and audio errors that occur when delivering video over any wireless network. As a result, Matrix II-based devices can reliably and consistently deliver a television-like viewing experience for the consumer.
Highlights of the Matrix II baseband processor include: dual independent 802.11 RF channels with true 2X bandwidth gains; enhanced error correction and enhanced signal detection to provide a 10 " 20 dB performance increase; transmission rate of up to 124 Mb/s; full interoperability with standard 802.11a/b/g data and video clients; support for 802.11e/h/i/j extensions; audio/video clock synchronization; high MAC efficiencies for increased throughput; hardware encryption/decryption support for Wi-Fi protected access (WPA) and IEEE 802.11i security without any performance degradation; and flexible support for multiple high-performance, high-volume 802.11a/b/g RF front-ends.
