Encoding and decoding of slot positions of events in an audio signal frame

摘要

An apparatus for decoding (10; 40; 60; 410), an apparatus for encoding (510), a method for decoding and a method for encoding positions of slots comprising events in an audio signal frame and respective computer programs and encoded signals, wherein the apparatus for decoding (10; 40; 60; 410) comprises: an analysing unit (20; 42; 70; 420) for analysing a frame slots number indicating the total of slots of the audio signal frame, an event slots number indicating the number of slots comprising the events of the audio signal frame, and an event state number, and a generating unit (30; 45; 80; 430) for generating an indication of a plurality of positions of slots comprising the events in the audio signal frame using the frame slots number, the event slots number and the event state number.
