METHOD FOR THE REDUCTION OF COMMUNICATIONS DATA WHICH IS TO BE TRANSMITTED AS USEFUL DATA WITHIN DATA PACKETS

摘要

The invention relates to a data compression method which obtains the information content of communications data comprised of voice data and non-voice data (or video data and non-video data). According to the invention, the data pattern occurring in the communications data is replaced by the code symbols allocated thereto. The allocation specification is determined by previous analysis exclusively of representative voice data (or video data). Data patterns are thus generally allocated shorter code symbols the more frequently the respective data pattern occurs in the analyzed voice data (or video data).
