Starz Entertainment has been making some pretty big moves of late, the most recent of which involves Motorola. The latter firm has announced that it will be "implementing a four-channel, high-definition MPEG-4/AVC encoding system" for Starz, which it will use to migrate away from its current MPEG-2 installations. It's reported that the change will enable Starz to "expand its HD offerings for subscribers," and as predicted, the system is being first implemented for the outfit's existing HD channels: Starz HD, Starz Kids and Family HD, Starz Edge HD and Starz Comedy HD. Oh, and if you were wondering, the recently unveiled Encore HD will be launched "concurrent with this migration."
