ABSTRACT:
A system for encoding, storing, and displaying captions includes a modem for transmitting a signal including one or more closed captions generated in real time, a videotape player for playing a videotape of a television program including both a video signal and a time code signal corresponding to a time position of the video tape, an encoder for receiving the video signal and a caption input and integrating the video signal and the caption input into one integrated signal for transmission, and a computer that receives captions from the modem and a time code output from the video tape player. The computer transmits the received captions to an encoder and simultaneously generates data records storing the received captions with a time code stamp corresponding to the time code signal input when the caption was received. When a playback of the captioned television program is desired, the computer retrieves the stored caption data record and synchronizes the time code stamp of each caption in the data record with the received time code output. Thus, the computer supplies the synchronized caption to the encoder for insertion into the video signal from the videotape player, whereby captions are provided for refeeds of television programs without requiring a second generation recording of the originally captioned feed.
