1. A method of producing a real-time video stream from stored MPEG encoded video clips, the MPEG encoded video clips being contained in data storage of a video server, the method comprising:

  • reading segments of the MPEG encoded video clips from the data storage, the segments of the MPEG encoded video clips being decoded by respective first and second decoders in a decoder pair, the first decoder decoding at least a portion of a first MPEG encoded video clip and the second decoder decoding at least a portion of a second MPEG encoded video clip, the real-time video stream being obtained by operating a video switch to switch between a video output of the first decoder and a video output of the second decoder to select a specified In-point frame in the second MPEG encoded video clip that is selectable as any MPEG frame type at any location in an MPEG group of pictures (GOP) structure.
