This invention relates to methods for forming a substantially continuous composite video signal. A method for forming a composite signal comprises providing a video signal preprogrammed with data, reading or decoding and storing the data, determining where to combine a video field assembled from the data with the video signal, and combining the video field with the video signal by switching between the two. A method for forming a substantially continuous video signal comprises providing a video signal preprogrammed with data, reading or decoding and storing the data, receiving input indicating a desired video signal segment, determining the gap before locating the desired video signal segment, and filling the gap with a video segment assembled from the data. In another aspect, this invention also relates to a device for carrying out the methods of the invention. |
