SIGNAL COMPRESSING SYSTEM

摘要

A multi-scanner (80) scans a signal according to a plurality of different patterns and a scanning pattern selector (90) determines which scanning pattern produces the most efficient coding result, for example for runlength coding. The selected signal is multiplexed with a signal which identifies the selected scanning pattern. preferably after variable length encoding 60. As described, the signal is an image signal which has undergone discrete cosine transformation (10) after media compensation (10). Eight different scanning or sampling patterns are disclosed (Figure 3).
