Abstract: A method and system is disclosed for transmitting audio and video data to a remote viewing station. The method includes the steps of receiving a signal at a control station representing a request for the audio and video data. The method further includes determining whether the requested data is stored at a mass storage facility or at an active line storage unit. If the requested data is stored at the mass storage facility, the method includes downloading and storing the data at the active line storage unit. Finally, the method includes the step of transmitting the stored data from the active line storage unit to the remote viewing station.

Abstract: The present invention is a system and method for retrieving segments of stored video programs using closed caption text data. The closed caption text data is extracted from video programming signals received by the invention. Text records based on the extracted closed caption data are generated. Each text record is derived from the closed caption data for a single continuous video segment to which the text record serves as an index or key in retrieving this video segment. Preferably, each text record (a) has sufficient content to adequately describe the content of the video segment to which it serves as an index; and (b) corresponds to a video segment focused on a small number of topics. To accomplish (a) and (b) the present invention generates each text record so that it has a predetermined maximum length and so that it is derived from the closed caption data for a single uninterrupted speaker.
