A system for performing closed captioning enables a caption prepared remotely by a captioner to be repositioned by someone other than the captioner, such as by a program originator. This capability is particularly useful when, for example, the program originator wishes to include a banner in a video but also wishes to avoid having a closed caption interfere with the banner. In one illustrative system, the program originator is a broadcast station that includes a conventional encoder and a broadcast station computer. In one arrangement, control data generated at the station computer is incorporated into the caption data by the station computer in another arrangement, the control data is sent from the station computer to the captioner computer, which incorporates the control data into the caption data.
