Harmonic's new DiviCom Ion AVC standard definition encoder has successfully completed encoder conformance testing for the Microsoft Mediaroom IPTV and multimedia software platform. The test was administered by Microsoft as part of the Microsoft Mediaroom Interoperability and Qualification Lab program, which is intended to enable the ongoing interoperability and compliance of encoders used in deployments of Microsoft Mediaroom. A Microsoft Mediaroom ecosystem partner, Harmonic powers the video headends for a majority of Microsoft’s IPTV customers. Harmonic delivers over 5,000 broadcast video channels around the world to more than four million IPTV subscribers, and counts more than 100 telco operators as its customers.

Able to deliver four simultaneous MPEG-4 AVC (H.264) SD channels in both high and low-resolution formats, the IP-based Ion AVC encoder offers service providers a dense, cost-effective and high-quality platform for constant bit-rate video delivery. Designed for service providers that need to meet the increasing demand for high-quality digital video services while minimizing capital and operating expenditures, the new Ion AVC is ideal for applications such as “long-tail” program delivery in a unicast environment, a key competitive differentiator for service providers.

The Ion AVC encoder was vigorously tested in both NTSC and PAL formats for feature set completeness, compression performance and service uptime in video and audio encoding, picture-in-picture, closed captioning and other categories. Other Harmonic products which have successfully completed the Mediaroom compliance testing include the DiviCom Electra 7000 HD MPEG-4 AVC (H.264) encoder and the Electra 5400 SD H.264 encoder.

Deployed or being trialed by more than 20 service providers worldwide on four continents and in 18 countries, Microsoft Mediaroom enables unique TV features and experiences, such as simultaneous recording of multiple high-definition and standard-definition TV channels, personal media sharing, whole-home and remote digital video recording, and multiple picture-in-picture scenarios. The award-winning platform, which is delivering video entertainment experiences to more than 1 million set-top boxes worldwide, also integrates with the Xbox 360 gaming device, bringing together next-generation television and gaming offerings into an integrated entertainment experience. Microsoft Mediaroom allows third parties to create exciting new TV applications and services that enrich the TV viewing experience through the multimedia application environment in the platform.

Harmonic’s portfolio of solutions for telco IPTV service providers encompasses compression and stream processing at the headend, video servers and on-demand software, and targeted advertisement insertion.
