发明名称 Method and system for providing interactive media VCR control
摘要 A method and system for providing flexible subscriber VCR control of an interactive media system that limits the consumption of bandwidth capacity, the method comprising establishing a viewing time window during which a subscriber can watch an ordered program, enabling the subscriber to freely pause, rewind, and fast-forward the program so long as the end of the program does not exceed the end of the window, automatically tracking the remaining program running time against the time remaining in the window, deactivating the pause and rewind features if the remaining program running time equals the time remaining in the window, and reactivating the pause and rewind features if the program is fast-forwarded such that the time remaining in the window exceeds the remaining program running time. The system of the present invention is any interactive media system that delivers video streams such as an interactive television system that supports services such as pay-per-view and video-on-demand, or an internet-based interactive media system that downloads video streams through the internet to be played on a subscriber's personal computer or other viewing device.
