Abstract
An audio and video reproduction apparatus that comprises a memory, a display screen, and circuitry. The memory stores a sequence of image frames of multi-media content and closed caption (CC) information associated with the multi-media content. The circuitry detects a first position of a first object in an image frame, of the sequence of image frames, to be displayed on the display screen. The circuitry further controls, based on a user-input, the display screen to display the image frame in a first display portion of the display screen and display a first portion of the CC information at a second position in a second display portion of the display screen. The first portion of the CC information is displayed at the second position in the second display portion, based on the detected first position of the first object in the image frame.
