AT&T to Deploy First Standards-Based HD-SDI Switching Capability to Distribute Contribution Video


AT&Tís Intelligent Layer 1 Optical Network Combines with Next Generation Video Transport Technology

Las Vegas, Nevada, AT&T* today announced plans to deploy the industryís first standards-based High Definition-SDI video transport and switching network capability designed for the professional broadcast marketplace and customers using AT&Tís Global Video Services.

The new feature will combine AT&Tís ultra fast, self-healing SONET optical network with next-generation video transport technology based on JPEG2000 compression standards. It will support HD-SDI at rates between 75Mb and 400Mb along with SD-SDI at 24Mb to 150Mb.

Following a successful pilot program in January, AT&T expects to start delivering the feature utilizing JPEG2000 compression capabilities beginning 3Q 2010 in major metropolitan areas across North America.

ďThis enhancement to our AT&T Global Video Services portfolio will enable broadcast customers to take advantage of a cost-effective, high availability, high quality compression process for migrating to next generation video services such as 3D and higher-quality HD,Ē said Sanford Brown, vice president, AT&T Connectivity and Metro Network Services. ďAT&T has the ability to reach many media outlets on a global scale with a high level of network redundancy and resiliency ó and now with JPEG2000 compression technology planned ó for an unparalleled viewing experience.Ē

The new capability will provide something that broadcasters, content providers and production studios have been looking for -- innovative and cost-effective access to higher bit rate video services over reliable delivery methods. It is designed to help these businesses improve the viewing experience for consumers demanding video over traditional cable television in addition to new endpoints such as mobile phones and the Internet.

Whatís more, it will address broadcastersí needs to incorporate JPEG2000 compression technology while having to balance capital outlays for the necessary compression equipment with pressures on advertising revenues. Delivering high quality compression technology through AT&Tís network can allow broadcast customers to focus more dollars around reaching more locations to generate more advertising dollars.
