Systeme et procede pour la reproduction des dates d'un tampon circulaire en utilisant des horodatages integrees

System und Verfahren zur Datenwiedergabe von einem Ringpuffer mittels eingebetteter Zeitmarken

Abstract

A system for playing back data from a circular buffer is disclosed. The system includes: a buffer, for buffering data, wherein the data is encoded and grouped into Data Units (DUs), each containing an embedded timestamp; a buffer access module, for utilizing a write pointer to record data to the buffer, and for utilizing a read pointer to play back data from the buffer, wherein a DU pointed to by the write pointer corresponds to a current timestamp; and a computing unit, for comparing a timestamp pointed to by the read pointer with the current timestamp, and utilizing the comparison result to determine the validity of playing back data indicated by the read pointer.
