1. A method comprising:
playing a single video image including video frames and a single on-screen display at a time, said single on-screen display at a time extracted from a first memory and processed for playing in the single video image by a video processor; receiving an identification of a prior on-screen display associated with a prior video frame already played, wherein said identification indicates the prior on-screen display via a time interval measured prior to a time of a current video frame being played, the prior on-screen display including at least one of a subtitle and a closed caption; determining, via a recall processor and based on the time interval indicated in said identification, a memory read pointer associated with a particular location in a second memory for locating and extracting the prior on-screen display stored in the second memory, wherein the extracted prior on-screen display has occurred prior to the current video frame by an amount of time substantially as set forth in the identification; and enabling, via the video processor, display of at least the extracted prior on-screen display associated with the prior video frame already played together with said current video frame and any subsequent video frames, said at least the extracted prior on-screen enabled for display to play as the single on-screen display at a time in the single video image without interrupting said playing of said current video frame and any subsequent video frames in said single video image, wherein said enabling display includes displaying said at least one of the subtitle and the closed caption included in the extracted prior on-screen display on multiple lines at a first location that is other than a second location normally used for displaying on-screen displays for the current video frame and at a first line display rate that is faster than a second line display rate normally employed for an on-screen display for the current video frame.
