DiBcom Launches New Very Low Power Mobile TV Receivers

TV reception using DVB-T and Full-SEG ISDB-T is now available on small battery powered devices

Paris, 10 September 2008: DiBcom, the leading provider of Mobile TV solutions, is pleased to announce two new products, the DIB9090 and DIB8090 which both support very low power mobile TV reception of DVB-T and ISDB-T 13SEG signals respectively. These chips also support the reception of DVB-H and ISDB-T 1SEG.

Historically, numerous countries have deployed DVB-T and ISDB-T Full-SEG for non mobile applications such as Home Digital TVs and Set Top Boxes/Digital Converters. Since June 2008, mobile phones using DiBcom chipsets have offered DVB-T reception in several European countries. In Japan, where 1SEG ISDB-T has been deployed on mobile phones, more than 30 Million units have already been sold and handset manufacturers are also starting to look at implementing reception of Full-SEG ISDB-T. This will enable them to offer high definition TV on large screen mobile phones.

However, DVB-T and Full-SEG ISDB-T currently use high level modulation schemes to transmit high bit-rate TV signals (Standard or High-Definition TV) making reception difficult in mobile conditions. The strong channel variations, the Doppler effect related to mobility and the adjacent channels are indeed much stronger when receiving high modulation signals compared to low bit-rate QVGA-size TV signals transmitted by DVB-H or ISDB-T 1SEG. DiBcom released the first Mobile TV DVB-T receivers for the automotive industry back in 2002. Yet it took another six years to reduce power consumption, size, and the number of discrete components to significantly low levels without compromising the high level performance that made DiBcom a leading Mobile TV reference.

The new generation of components like the DIB9090 and the DIB8090, has revolutionised the Mobile TV market by offering the highest performance at the lowest possible power consumption in all functional modes (for DVB-T and Full-SEG ISDB-T in particular). These new generation components draw on the successful features of their predecessors in addition to their small footprint. They therefore provide a very cost effective solution for DVB-T, DVB-H, Full-SEG and 1SEG ISDB-T Mobile TV reception on battery-powered devices. While others claim to provide low power solutions, their disappointing performance makes them unsuitable for DVB-T or Full-SEG ISDB-T reception. High linearity tuners as well as advanced signal processing algorithms implemented on smaller silicon geometries are vital for this performance vs. power trade-off.

“We are very pleased to see handsets implementing both DVB-T and DVB-H on the same platforms”, says Yannick Levy, CEO of DiBcom. “DVB-T based Free-To-Air TV signals are broadcast in many countries today, thus making it very attractive for consumers to try out TV reception on handhelds. Once users are hooked, they will demand more content and better coverage. In this way, they are more likely to subscribe to DVB-H services and watch more content on 3G. Handset manufacturers now see a real opportunity to create higher volumes compared to the levels that DVB-H only devices can achieve. This new feature is therefore a very attractive one to differentiate their products.”

A demo of the new DiBcom chips and many commercial products using DiBcom solutions will be shown in the DiBcom booth (A41, Hall 3) at IBC from September 12th to 16th.

Agito Networks to Premiere Next Generation of Enterprise-Grade Mobile Convergence Products at Mobile Business Expo 2008

VP of Marketing and Co-Founder Pejman Roshan to Present on “Convergence – Or Not” Panel for Better Understanding of Mobile Convergence Options and Advantages for Enterprises

SANTA CLARA, Calif. – Sept. 10, 2008 – Agito Networks, Inc., the company delivering new technology in enterprise mobility, today announced it will unveil and demonstrate publicly for the first time the next-generation version of its RoamAnywhere Mobility Router at Mobile Business Expo (MBX) 2008 in its booth No. 810.  The event takes place at the Javits Convention Center in New York, and runs from Sept. 16 – 19.

Agito’s award-winning RoamAnywhere Mobility Router is the industry’s most powerful enterprise fixed mobile convergence (eFMC) product, purpose built for enterprises to help them increase mobile worker productivity while reducing cellular costs (  Industry firsts in Agito’s new enterprise mobility release on display at Interop NY/MBX next week include Secure Remote Voice for secure voice over WLAN (VoWLAN), Dual Persona for converged enterprise and personal functionality on a single device, advances in Dynamic Least Cost Routing for further cellular cost savings, and the broadest PBX and Nokia/Windows Mobile handset support available.

Agito Networks uniquely fuses Wi-Fi, cellular, IP telephony, and location information, improving the accessibility and responsiveness of mobile workers, while drastically reducing mobile costs.  RoamAnywhere uses the industry’s most complete set of proactive, location- and policy-based metrics, in addition to simplistic reactive metrics, to deliver fast and automatic, sub-100ms handover of mobile voice between WLAN and cellular networks.  Other solutions rely solely on reactive, “call-in-distress” metrics, such as diminishing signal strength and degrading voice quality, waiting for the call to degrade before attempting a handover.  RoamAnywhere adds proactive metrics, including location- and policy-based metrics, such as handset battery levels and network costs, into its handover decisions, delivering the best mobile voice experience for users.

“Over the past year we have seen dramatic developments in the enterprise mobility and fixed mobile convergence (FMC) marketplace, and a rising adoption from enterprises,” said General Manager of Mobile Business Expo Steve Wylie.  “Mobile convergence is a central theme of the expo this year, and we’re pleased Agito selected our event to unveil the next-generation release of RoamAnywhere, publicly debuting the product’s enhancements for conference attendees.”

During the event, wireless expert and Agito Networks VP of Marketing Pejman Roshan will present on the event’s “Convergence – Or Not” panel on Thurs., Sept. 18, at 10:15 am EDT.  The session will explore the advantages of various FMC approaches, and the best options available for enterprise IT and telecom managers’ specific environments and requirements.

Also, Sandeep Rangarajan, senior product line manager at Agito Networks, will present “Is Fixed Mobile Convergence Ready for the Enterprise?” in the Market Leaders Track on Weds., Sept. 17, at 4 pm EDT in the exhibition hall theater.  Attendees will learn about enterprise-ready technology that provides mobile workers with productivity gains by mobilizing voice and data applications, while enabling IT to retain control over costs, mobile service, and mobile users.

Mr. Roshan has more than 17 years of wireless expertise and an extensive track record.  Prior to co-founding Agito Networks, Mr. Roshan was Product Line Manager in the Cisco Systems Wireless Networking Business Unit (WNBU), responsible for software, security, voice and WLAN management products.  Roshan joined Cisco’s WNBU just after its acquisition of Aironet in 2000, helping drive Cisco’s wireless market leadership position.  Before that, Mr. Roshan spent eight years as a network engineer and architect, designing and deploying large-scale networks for companies such as Cisco Systems and Automatic Data Processing (ADP).  Mr. Roshan’s accomplishments include participation in the IEEE 802.11 task groups responsible for security (802.11i) and QoS (802.11e); co-authoring the book 802.11 Wireless LAN Fundamentals, published by the Cisco Press in 2004; as well as publishing numerous wireless security and wireless voice white papers.  He earned a B.S. degree in Business Administration from Cal Poly University.

Mr. Rangarajan has more than 12 years of experience in the networking industry.  Previously, he held senior Engineering and Product Management positions at Neoteris (acquired by Juniper), largely responsible for the client-server proxy, VPN engineering and product management efforts for its SSL VPN product line.  Prior to joining Neoteris, Mr. Rangarajan was a senior systems engineering and field specialist at Alteon WebSystems (acquired by Nortel Networks), responsible for leading the western region pre-sales technical designs and implementations.  Prior to that, Mr. Rangarajan was part of the core development team within the Cisco IOS/ENA Technologies Division.  He holds a B.S. degree in Computer Science Engineering from The Ohio State University and is currently pursuing his MBA at Santa Clara University.
