METHOD AND DEVICE FOR ADAPTING THE DATA RATE OF A DATA STREAM

摘要

The invention relates to an improved method and to a corresponding device for adapting the data rate of a data stream while using a first in, first out (FIFO) memory (1) into which data packets of the data stream with a first data rate are written and out of which the data packets are output with a second data rate. According to the invention, a designated pause (TP) is inserted after each output data packet until the next data packet is output. In the event of a no-load operation of the FIFO memory (1), an additional pause (TFE) results, which is detected. In addition, the number of the data packets output between a preceding no-load operation and the current no-load operation of the FIFO memory (1) is determined. A longest pause between the data packets can be determined based on this information. Independent of a comparison of this longest pause with the product of the output data packets between two consecutive FIFO no-load operations and the pause (TP) to be inserted between the output data packets, it is determined whether an increase of the inserted pause (TP) is most likely.
