Abstract
Switched digital television programming for video-on-demand and other interactive television services are combined utilizing class-based, multi-dimensional decision logic to simultaneously optimize video quality and audio uniformity while minimizing latency during user interactions with the system over an unmanaged network. For example, a method of adapting content-stream bandwidth includes generating a content stream for transmission over an unmanaged network with varying capacity; sending the content stream, via the unmanaged network, toward a client device; monitoring the capacity of the unmanaged network; determining whether an aggregate bandwidth of an upcoming portion of the content stream fits the capacity, wherein the upcoming portion of the content stream corresponds to a respective frame time and includes video content and user-interface data; and, in response to a determination that the aggregate bandwidth does not fit the capacity, reducing a size of the upcoming portion of the content stream.
