The invention relates to a method for the mobile reception and playback of high-frequency television signals. The received signals are fed to a tuner and a demodulator. The received signals are demodulated, divided at least into video and audio signals by a demultiplexer, and fed as data to a video and audio decoder. Said procedure occurs in parallel in at least two reception paths before the video and audio decoder. The method is characterized in that the data of the one reception line are stored by a circular buffer, the data being processed and made available for playback by means of the other reception line, the video decoder receiving the data stored in the circular buffer for further processing if a switch is made from the other reception line to the one reception line.
