NextWave Wireless Inc. has launched MXtv, a breakthrough mobile multicast and broadcast technology that enables WiMAX operators to deliver a broad range of rich and personalized multimedia services including mobile TV, interactive media services, and digital audio without having to invest in new spectrum or additional radio access network equipment. Utilizing cutting-edge macro-diversity technology that significantly improves broadcast performance over WiMAX channel, MXtv technology, which is completely compatible with the current 802.16e standard, is designed to slash the cost of offering high-quality, mobile broadcast services to subscribers.
Supporting 30fps QVGA and WQVGA content, MXtv technology provides up to 45 high-quality mobile TV channels in 10MHz with rapid channel switching times of under 2s, and offers network operators the unique ability to dynamically allocate spectrum based on content availability, time-of-day requirements, user demand, and the availability of "must see" live events such as sports, concerts, interactive reality shows or emergency broadcasts. With the unique ability to interleave broadcast content with voice and data content in each user transmission, MXtv enables WiMAX network operators to maximize service revenues by allowing them to dynamically optimize the mix of voice, data, and broadcast services on each RF carrier based on user demand, service pricing and advertising revenue. Furthermore, over 300 high fidelity radio broadcast channels or any combination of mobile TV, personalized radio, voice and data services can be offered in the same 10 MHz of spectrum.
Similar to the company's end-to-end TDtv solution for UMTS operators, MXtv utilizes advanced macro-diversity technology to deliver optimal performance and does not require operators to acquire additional expensive spectrum to enter the mobile TV market.
For non-cellular consumer devices like personal media players, handheld gaming or navigational devices and DVD players, MXtv offers an easy and cost-effective way to integrate interactive mobile TV services with a built-in return channel. Coupled with the ability to offer unicast on-demand services on the same spectrum, network operators can additionally offer a compelling program guide with the combination of the live broadcast content, on-device stored content of earlier broadcasts for more efficient distribution, personal content as well as a wide range of user-specific content including specialized or educational content, informational content, user-community content, regional and local content using either subscription or advertising supported business models. The operator also has the ability to broadcast specific content on a defined geographical basis to tailor the available content for each individual user.
MXtv mirrors the architecture and leverages the MBMS core network design that NextWave has built to support its recently announced commercial pilot of TDtv with leading tier one UK operators. The end-to-end solution is comprised of MXtv-enabled WiMAX network infrastructure from NextWave or other leading network equipment vendors, subscriber terminals powered by the company's NW2000 MXtv-enabled WiMAX System-on-a-Chip (SoC), and the MediaFusion multimedia content management, discovery and advertising platform provided by PacketVideo (PV), a subsidiary of NextWave Wireless and an industry leader in multimedia client solutions.
