Abstract: A digital audio player (10) and a method for processing encoded digital audio data. The audio data player has a hard disk or other data storage medium (32) for storing data files, a microcontroller (22), buffer memory (25) for anti-skip protection, and an audio decoder (12). The encoded audio data files and associated decoder files are downloaded from a personal computer or similar device to the audio data player hard drive (32). The data structure generally includes a first audio data file having an information segment and an audio data segment. The information segment, generally called a tag, may include textual and graphic information related to the audio data segment. The present invention further includes an additional data frame in the information segment storing one or more audio data files, or “audio tag files”. The audio tag files stored in the information segment include encoded audible or voice recordings that vocalize other tag information related to the audio data segment.

Abstract: A method and apparatus is disclosed for detecting and concealing errors in stored digital samples. A multibit digital input sample is received and an error detecting code, corresponding to that input sample is calculated. Then a multibit digital storage sample is generated by substituting the error detecting code for the same number of least significant bits of the input sample. The storage sample is then stored in a memory device. A previously stored sample is retrieved from the memory device and is analyzed to detect whether an error has occurred. If an error is detected, a substitute sample is produced for the retrieved sample, otherwise the retrieved sample is produced.
