  • Patent number: 6243465
    Abstract: A method for providing video programming in a nearly on demand basis is disclosed. A video network includes a video server that operates several video recorders to simultaneously exhibit video performances or programs on a plurality of channels. The video server is controlled in real time in accordance with data presented to it in an exhibition plan. The exhibition plan calls for two or more channels to show the same program on a time offset basis. Due to the offset in exhibiting a given program, a subscriber may view a program at any time, from the beginning of a program, by waiting for a period of time that is no longer than the offset. Preferably, this offset is substantially shorter than the run time of the program. The channels carrying this program are unscrambled prior to the beginning of the program and for a predetermined duration into the program so that subscribers may preview the program. However, the channels are scrambled for the remainder of the exhibition of the program.

  • Patent number: 5168353
    Abstract: System for distributing video programs includes a transmission system having a plurality of channels, includes a stored database representing a predetermined schedule including timing instructions. A computer is programmed to provide real time outputs in response to the database time instructions. A bus has an input coupled to the computer and providing control signals in response to the real time outputs. A recorded media contains programs in television format. A plurality of video players are used for playing the recorded media, each video player having a control port coupled to the bus and responsive to the control signals. Each video player has an output providing television signals for coupling to a separate corresponding channel, and at least two of the video players loaded with duplicate recorded media and controlled to play at staggered overlapping time intervals.
