PROCESSING AND REPRODUCTION OF FRAMES

摘要

A processor (12) is configured to receive input data (10), divide an individual frame (1) into blocks, compare the blocks with corresponding blocks of a first prediction frame for (2) and identify changed blocks (3). In order to obtain an efficient solution for processing and reproducing frames, the processor is configured to include in generated intermediate data (7) the blocks identified as changed blocks (3), and generate a change indicator (8) indicating the positions in the individual frame (1) of the identified changed blocks (3) and identified unchanged blocks (4).
