摘要
The present invention relates to a method for generating a stream of digital packets by means of an apparatus. The apparatus receives data packets sequentially transmitted in an isochronous stream and containing a series of data samples, e.g. sound data. The apparatus transmits a predetermined number of samples in frames that encode a series of samples starting with a first sample. The apparatus determines the value of a number identifying each sample contained in the input stream. The value of the number of said first sample in each frame is a multiple, possibly zero, of the predetermined number of samples. In this manner, regardless of the encoder that produces the frames, the latter contain the same samples without any shift from one encoder to the next. The switching between the output streams transmitted by a plurality of encoders can be carried out without any artifacts due to the transmission of the same samples.
