Abstract
Methods and apparatus for performing dynamic compensation for delays over extant infrastructure within a content-based network. In one embodiment, the network comprises a cable network, and the infrastructure comprises that nominally used for on-demand (OD) services such as VOD. The method includes periodically or situationally assessing variable delays within the system associated with functional commands (such as “trick mode” commands), and dynamically compensating for these variable delays in order to improve the accuracy and timeliness of the user's trick mode command. This approach increases user satisfaction, and obviates the issuance of additional compensatory trick mode commands that only further degrade the performance of the network.
