Abstract: Methods, systems, and computer readable media can be operable to facilitate regulation of trickplay control during playback of streaming multimedia. Trickplay control can be regulated by associating a segment of a multimedia stream with a finite state automaton, associating a state of the finite state automaton with a flag, and controlling transitions from state to state within the finite state automaton by client interactions with the multimedia stream or predetermined time period.

Abstract: A digital splicing process includes calculating the length of data to be inserted into a transport stream between first and second video clips; and removing B-frames in the second clip that reference non-existent I-frames without replacing the removed B-frames with new B-frames.

Abstract: A custom ad selection and delivery system may include an ad selector to select candidate ads for one or more ad avail opportunities, a bandwidth resource manager to provide information about available bandwidth in a content delivery system, and a policy manager to weight ad avail opportunity versus bandwidth costs to delivery customized advertising to subscribers, and to cause allocation of bandwidth and insertion of customized ads into multiple program streams comprising the same program content but different ad content, and to cause different subscriber equipment to map different program frequencies to similar content streams having advertising content inserted therein that is customized to different subscriber demographics.
