System for encoding and displaying captions for television programs
First Claim
1. A method of providing captions for a television signal, the captions comprising a plurality of words to be superpositioned over a video portion of the television signal, the method comprising the steps of:
- transmitting a caption data signal over a telephone line to a computer;
monitoring time code signals from a video program provided by a video player, said caption data signal corresponding to said video program;
outputting said caption data signal from said computer when a match is detected between a time code signal of said caption data signal and a time code signal of said video program;
inserting said output caption data signal into the video signal of said video program; and
generating and transmitting to a remote terminal acknowledgement signals indicating operating status of said computer.

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.

7. An apparatus for providing captions for a television signal, the captions comprising a plurality of words to be superpositioned over a video portion of the television signal, the apparatus comprising:
-
a modem for transmitting caption data over a telephone line; a videotape player for playing a videotape, the videotape player outputting a video program signal and a time code signal corresponding to a time position of the videotape; a computer for receiving said caption data from said modem, monitoring said time code signal output from said videotape player, outputting said caption data when a match is detected between a time code signal of said caption data signal and said time code signal from said videotape player, and generating and transmitting to a remote terminal acknowledgement signals indicating operating status of the computer, and an encoder for inserting said output caption data signal into said video program signal. - View Dependent Claims (8, 9, 10, 11)
