Envivio Selected to Provide High Quality Video and Audio Encoding for MPH™ Mobile TV Demo at NAB 2008

4Caster M2 Encoders Enable Harris and LG Electronics to Present Live Showcase of Proposed IP-based Delivery Platform

The MPH partners, Harris Corporation, LG Electronics and Zenith, will demonstrate the capabilities of their IP-based delivery system in an over-the-air (OTA) MPH mobile DTV broadcast by KVCW-DT, a Sinclair Broadcasting Group-owned station serving the Las Vegas market.  IP-based delivery will also be demonstrated on a closed circuit broadcast originating from the Harris Booth (N2502) in the North Hall of the Las Vegas Convention Center at the 2008 National Association of Broadcasters (NAB) convention from April 14-17.

For the demonstration Envivio has provided versions of its 4Caster M2 encoders which support the requirements of the MPH system. As the world’s leading supplier of encoding solutions for mobile TV, Envivio encoding systems already power hundreds of mobile TV encoder deployments worldwide. The flexible design of Envivio’s 4Caster M2 enables the company to rapidly accommodate evolving mobile TV requirements such as MPH within its existing 4Caster M2 product.

The IP-based delivery system takes the high-quality encoded content provided by the 4Caster M2 and uses a new station-side platform developed jointly by Triveni Digital and UDcast to enable IP encapsulation within the legacy MPEG-2 transport stream. This system meets the Advanced Television Systems Committee (ATSC) requirements for a new technology called ATSC-M/H, which will enable the delivery of in-band television content and data to mobile and handheld devices via DTV broadcast signals.

The MPH demonstration relies on high-quality audio and video delivered at very efficient data rates to reliably deliver multiple channels of content and interactive services to devices that are on the move. With its inherent flexibility and power to output multiple device profiles simultaneously, the 4Caster M2 delivers an optimum mobile TV viewing experience to any mobile device via any transmission infrastructure.
