Technical Examples
  1. A method for scrolling MPEG-compressed pictures consists in decoding a sequence of pictures (34, 35, 36) or any two pictures to be viewed by a MPEG decoder (5) and storing the sequence of pictures (35, 35, 36) or any two pictures in MPEG decoder memory. Then the sequence of pictures (34, 35, 36) or any two pictures is formed as a group of pictures (37), which is transferred to the first screen buffer (24) which is active. In the following step, any another compressed picture, after decoding in the MPEG decoder (5), is stored in a MPEG decoder memory as a decoder new picture and then is transferred from the MPEG decoder memory to the first screen buffer (24), where its edge line perpendicular to the intended scrolling direction is adjoined to the external edge of the group of pictures (37). The new picture is placed outside the viewing area and next the entire viewing area is shifted until the marginal picture lying at the opposite side of the group of pictures (37) in relation to the adjoined new picture is removed from the viewing area (21), and the newly decoded picture is placed in this area.
