New MPEG-4 encoding system dramatically improves bandwidth efficiency for Starz and Encore high-definition channels

Motorola (NYSE:MOT) today announced it is implementing a four-channel, high-definition (HD) MPEG-4/AVC encoding system for Starz Entertainment, a premium movie service provider in the United States, to begin migration from current MPEG-2 installations to MPEG-4 installations. The system compresses, encrypts, modulates, and receives HD signals within a single integrated transmission system to allow Starz to expand its HD offerings for subscribers. The system is currently being implemented for Starz Entertainment’s existing HD channels, Starz, Starz Kids and Family HD, Starz Edge HD and Starz Comedy HD. The latest addition to Starz Entertainment’s HD movie channel lineup, Encore HD, will be launched in MPEG-4 concurrent with this migration.

ARM has released highly optimized source code versions of the OpenMAX DL (Development Layer) libraries for decoding the AAC and MP3 formats in the audio domain, and decoding the MPEG-4 and H.264 formats in the video domain. These functions can be downloaded free-of-charge from the ARM website http://www.arm.com/products/esd/openmax_home.html, and the license granted to these functions entitles the user to integrate them into their own products at no cost.
