A system and method for scrolling in a picture which is larger than MPEG standard in length or width or both in a video system, such as an interactive television system. In the preferred embodiment, the interactive television system comprises a video delivery system for providing video content, and at least one subscriber television including a display screen, wherein the subscriber television is coupled to the video delivery system. The video delivery system provides the compressed picture. The compressed picture has a length and/or a width which is larger than MPEG standard or alternatively is larger than the desirable viewing size. The compressed picture is subdivided into slices and possibly groups of slices such that the image may be smoothly scrolled. The subscriber television receives the compressed picture and operates to scroll in the compressed picture as desired by the user. The scrolling operation preferably includes providing additional compressed picture slices for decoding in place of slices in a previously viewed image of a portion of the compressed picture. The subscriber television then decodes the resulting picture and displays a next portion of the scrolled picture.
