Abstract
An image storing and/or replaying apparatus and a method therefor capable of storing a transient image and replaying the stored image at a desired time, the apparatus receives a broadcast stream including a plurality of still image frames and replays the images on a screen. The apparatus includes an image unit, which extracts and stores at least a portion of the plurality of the still image frames and replays the stored still image frames; and a control unit, which controls the extracting, storing, and replaying operations. The apparatus can be adapted to digital and analog broadcasts. In addition, in case of the digital broadcast, an I-frame may be extracted from a compressed image frame and stored. In particular, only some portion of the I-frame, that is, a lower slice of the I-frame, may be stored.
