| 摘要 |
The invention relates to a method for coding signals, specially digitized audio signals, comprising a coding device for coding said signals in a coding format and a processing device for processing said coded signals. Methods of this kind are, for example, already known in European Patent Document 290581. Therein, psychoacoustical phenomena are used in the perception of audio signals in a digitized form, e.g. 48 kHz sampling frequency/16 bit resolution, to substantially reduce the original bit rate of the audio signals. Such methods are currently standardized under "source coding" (ISO 11172 and 11318). The aim of the invention is to provide a method as mentioned above, which solves the cited problems and which extensively avoids transcoding once coding has occurred. According to the invention, this is achieved by determining the coding format according to the properties of the processing device in the above-mentioned method. |
