Envivio Provides Encoding for A-VSB Initiative’s Live ATSC-M/H Mobile Broadcast TV Demonstration at NAB

4Caster M2 Encoders Enable Delivery of Multiple Live Channels and Interactivity to a Wide Variety of Mobile Devices

The A-VSB Initiative demonstration showcases a mobile TV broadcast from a local TV station. It includes live simulcasts of a local TV channel and a national channel distributed over the station’s existing DTV transmission infrastructure. In addition, two interactive channels of content encoded using Envivio systems are being distributed to enable the A-VSB Initiative to illustrate user interactivity and electronic program guide (EPG) functionality. The A-VSB Initiative demonstration can be viewed at its booth (Hall C, Booth 1539) and also on the move via a bus tour.

As the world’s leading supplier of encoding solutions for mobile TV, Envivio products power hundreds of mobile TV deployments worldwide. The A-VSB Initiative’s mobile broadcast TV demonstration required an encoding solution that could deliver high quality video and audio at less than 500 kbps to a broad range of devices.  Envivio was able to optimize the parameters within the 4Caster M2 encoder to ensure a high quality experience on all the devices simultaneously.

The flexible design of Envivio’s encoding architecture enables the company to accommodate evolving mobile TV requirements, such as A-VSB, quickly and easily within its existing, widely deployed 4Caster M2 product. With its built-in support for multi-profile encoding, and advanced statistical and network aware rate controls, the 4Caster M2 delivers the optimum mobile TV viewing experience to any mobile device via any transmission infrastructure.
