Patent ID: 8550978

Claim:
A system for receiving and controlling reproduction of at least part of a source signal comprising video signals and music signals, via monitoring of a state of relaxation of a person, which system comprises: a device for receiving the source signal; sensor means for detecting at least one changeable physiological characteristic of the person, as the person progresses from an awake state into a sleep state, which characteristic assumes different values depending on different sleep phases of the person; analyzing means for recognizing sleep phases on a basis of the at least one changing physiological characteristic detected by the sensor means and for outputting control information characteristic of the sleep phases; and, control means, which control means include reproduction-speed control-means, which are arranged for changing a speed for the reproduction of the music signals based on the at least one detected changing physiological characteristic, such that the speed of reproduction is changed to match the physiological characteristic, and which control means are arranged for receiving the control information and terminating the reproduction of the music signals after receiving control information characteristic of a commencing of a certain sleep phase; wherein the control means are further adapted for activating video signal reproduction means to slow down a speed for the reproduction of the video signals dependent on the at least one detected physiological characteristic.
