Company Also Announces Its Terrestrial Interface Is Being Actively Shipped to Customers SAN JOSE, Calif., Sept. 7 /PRNewswire-FirstCall/ -- JDS Uniphase Corporation (Nasdaq: JDSU; TSX: JDU), the leading enabler of broadband and optical innovation, today announced the addition of Multicast Analysis capabilities to the DTS digital video services test and measurement solution. This addition underscores the company's commitment to supporting Digital and IP Video service providers around the world with the most effective tools to ensure efficiency and reliability when maintaining their networks and deploying new services. JDS Uniphase also announced that its recently launched terrestrial interface for the DTS is now being shipped to customers. JDS Uniphase, which recently acquired Acterna, will have the DTS Multicast Analysis feature, as well as traditional industry-leading test capabilities supporting the broadcast industry, on display at IBC 2005, September 8-14, Amsterdam, Hall 8, Booth 8.314. Launching Analysis of Multicast IP Video Services The new Multicast IP Video Services Analysis capabilities added to the DTS come at a critical time in the broadcast industry. For operators interested in ensuring accuracy, reliability and precision while delivering DV services via multicast to customers, the DTS digital video test product line delivers several features that help ensure a quality viewing experience. Operators using the multicast analysis feature can now turn their JDS Uniphase DTS test instrument into a more versatile digital video (DV) service-receiving device (similar to a STB) and can perform test functions to the digital video service remotely as if actually at the customer premise. This functionality enables proactive identification of trouble spots and improves operational efficiency and quality of service (QoS) within the network before potential problems reach the customer. It also enables operators deploying multicast video services to analyze their digital video services with ease-of-use, a hallmark of the DTS family of products. "Multicast analysis is important for operators providing advanced digital video services today -- JDS Uniphase has introduced new features to address problems, challenges and signal interference to enhance efficiency and reliability for operators managing multicasts," said Sudeep Bose, product line manager for the DTS product line. "Now, users can leverage the DTS tool's additional capability to quickly and easily join and leave multicast service groups, effectively minimize video services problems and provide higher quality of service for the viewer." Shipment of DTS's Terrestrial Broadcast Signal Analysis Interface JDS Uniphase also announced that shipment to customers has started for its recently released terrestrial broadcast interfaces, COFDM and 8VSB Modulations, designed to make the DTS digital video test instrument a single source to address the demands of digital video deployment. In September 2005, a number of broadcast customers around the world will be among the first to receive shipment and enjoy the benefits of the terrestrial interfaces and the COFDM and 8VSB modulations required in the global digital terrestrial television (DTTV) standards. For terrestrial broadcast engineers, these new COFDM and 8VSB interfaces combine to provide the single most comprehensive digital network test and measurement solution for rapid deployment of digital video services, accurate and precise signal analysis, lower operational cost and increase reliability. The terrestrial interfaces also provide the important function of RF analysis of the DTTV signal, allowing customers to determine whether or not the problem exists in the digital video service or in the DTTV transmission. Background: What is the DTS product line and why is it important for broadcasters at IBC? The DTS-330 and the DTS-200 are known in the industry for supporting new services deployment, such as IP Video, VOD and MPEG analysis, and are utilized to enhance digital, broadcast, satellite and terrestrial network quality. The recent addition of MPEG-4 real time analysis drives efficiency and instills confidence for broadcasters deploying the new and advanced compression technology in their digital networks. The DTS product line's powerful stream creation, generation, and analysis capabilities provide a complete solution for R&D (with aggressive design validation that enables multiplexer, set-top box, and digital TV manufacturers to reach the market faster and maintain system quality); deployment trials (testing digital terrestrial TV, video on demand, digital ad insertion, multimedia interactive applications, among others); system installation (allows integrators to solve configuration, inter-working, and performance issues prior to system acceptance and turn-up of the service); and network operation (generates base lining reports and monitors quality of service in both contribution and distribution networks.) The DTS is also the winner of the 2005 Diamond Award sponsored by Broadband Gear Report.
