A first playback device, upon receiving a synchronized playback command while content playback is in progress, transmits, to a second playback device, information that pertains to the playback content and a synchronized playback start time obtained by adding a predetermined additional time to an elapsed playback time for the content. The second playback device starts receiving content data that begins from the synchronized playback start time from a server. After the data that is memorized in a memory reaches a specified volume, the second playback device transmits a playback preparation completion notification to the first playback device. Once the elapsed playback time for the content reaches the synchronized playback start time, the first playback device transmits a playback start command to the second playback device. Upon receiving this command, the second playback device starts playing back content data that begins from the synchronized playback start time.

The invention relates to a signal processing method which optimizes the bit error rate under pragmatic conditions. The signalling method is optimally matched to the radio channel, variable with time, in rapid sequence by means of linear operations. Uplink and downlink transmission sides are determined by an excess of antennae on the downlink transmission side. The estimations of the channel matrix in the one transmission direction, necessary for the matching of the transmitter, can, in the absence of common-channel distortions with the condition of channel reciprocity, be directly obtained from the estimations for the other transmission direction. By a suitable linear combination of the transmission signals and, optionally, also the received signals, an error-free bi-directional transmission of data streams can be achieved in Rayleigh and Rice channels with significantly lower transmission powers than in purely receiver-side linear signal processing.
