Abstract

A file (FI) is transmitted via a first channel (CH1). In addition, a second channel (CH2) is used to transmit play parameters (D1, D2, R1, R2) which comprise at least one set (Di, Ri) of information about a play rate (R1, R2) and a delay time (D1, D2) for the file (FI) which is to be transmitted by the first channel (CH1). On the basis of the play parameters (D1, D2, R1, R2), it is possible to determine a time for starting to process the file (FI) which is to be transmitted.
