Abstract

There is set forth a method and a system for recording and synchronizing audio and video signals. The audio signal and the video signal are stored together with time stamps from a respective associated system clock. The invention relates to an adaptation of the duration of the recorded audio sequence to the duration of an associated video sequence in order to level out differences in synchronization of the two system clocks. Alignment of the two system clocks is also introduced, which is based on a data transfer which has variable waiting times for the access to a transmission channel. This thus permits clock alignment with means as are available for example on a smartphone.
