Method of managing an audio stream read in a manner that is synchronized on a reference clock

A method of managing an audio stream that is read by audio playback equipment in a manner that is synchronized on a reference clock, the audio playback equipment comprising an input buffer memory, the method comprising at least the following steps implemented in said piece of audio playback equipment:

• receiving the audio stream, the audio stream being in the form of packets, each packet comprising a succession of audio samples associated with at least a first identification information characteristic of a timestamp of said packet;
• playing the audio samples contained in each packet;
• the method further comprising the following steps implemented in the audio playback equipment:
• splitting each received packet into blocks of audio samples;
• determining at least a second timestamp information corresponding at least to one block of audio samples, both on the basis of the first identification information characteristic of a timestamp of the packet from which the block in question is extracted and also on the basis of the number of samples between a particular sample of said packet and a given sample of said block, the second timestamp information being determined by:
• point 1:
• calculation off an offset between the particular sample and the given sample;
• point 2:
• multiplication of offset of point 1 by a conversion ratio for converting a number of samples into timestamp information;
• point 3:
• addition of the result of point 2 to the first timestamp information in order to obtain the second timestamp information;
• injecting the block into the buffer memory by copying the block at the end of the buffer memory when reaching a predetermined threshold of available space in said buffer memory;
• the method comprising the steps of:
• storing a time given by the reference clock at the moment at which the given sample of the block is injected in the buffer memory,
• sending a message including at least one correspondence information between the first identification information characteristic of a timestamp of said packet and the time stored, the correspondence information comprising said second identification information corresponding to the block and said time stored.
