Abstract
Switched digital television programming for video-on-demand and other interactive television services are combined utilizing a class-based, multi-dimensional decision logic to simultaneously optimize video quality and audio uniformity while minimizing latency during user interactions with the system over managed networks such as cable and satellite television networks. A group of user sessions are assigned to a single modulator. The user sessions include data in a plurality of classes, each class having a respective priority. In response to a determination that an aggregate bandwidth of the group of user sessions for a first frame time exceeds a specified budget, bandwidth is allocated for the group of user sessions during the first frame time in accordance with the class priorities. The group of user sessions is multiplexed onto a channel corresponding to the modulator in accordance with the allocated bandwidth and transmitted over a managed network.
