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. A subscriber may order the program when it begins and for a short duration after the program becomes scrambled.

A fully-reversing 2.times.2 electromechanical optical switch apparatus is set forth. Input optical signals, carried on input optical fibers, are selectively transmitted to output optical fibers in a binary relationship. The invention utilizes a pair of supports which reciprocate with respect to one another, in which one or more of the supports carry one or more loops of optical fiber for switching the path of optical data carried on a fiber.

Moving 'S' fiber optical switch

A 2.times.2 optical switch employes a six-faced prism which can be moved from a first position to a second position. Mechanical latching means are used to maintain the second position without the necessity of applying continuous power to the moving means which preferably is a solenoid.
