Patent ID: 7519343

Claim:
A receiver for receiving a data stream generated by a transmitter, wherein the data stream comprises a first reference entry and a temporally following second reference entry, wherein the second reference entry comprises information about a number of clock periods performed by a clock oscillator in the transmitter since the first reference entry, comprising: a receiver clock oscillator controllable with regard to its receiver oscillator frequency; a detector for detecting a number of clock periods that the receiver clock oscillator performs in a specifiable period of time; an extractor for extracting the first and the second reference entry, wherein the extractor for extracting is implemented in order to control the detector for detecting on the basis of the extracted first and second reference entries with regard to the specifiable period of time; and a comparator for comparing the number of clock periods of the receiver clock oscillator to the information in the second reference entry, wherein the comparator for comparing is further implemented in order to control the receiver clock oscillator depending on a comparison result in order to increase or decrease the oscillator frequency such that the oscillator frequency is in a predetermined ratio to a frequency of the clock oscillator in the transmitter or is equal to the frequency of the clock oscillator in the transmitter, wherein the data stream further includes a sequence of samples or information as a payload from which the sequence of samples is derivable, wherein the sequence of samples is outputtable by a reproduction frequency that is derivable from a frequency of the receiver clock oscillator, wherein the reproduction frequency and the receiver oscillator frequency are in an integer ratio and the reproduction frequency is smaller than the receiver oscillator frequency, wherein the receiver further comprises: a direct frequency divider for providing the reproduction clock from the receiver oscillator clock, and wherein the data stream is specified according to a format IEEE 1394, wherein the receiver oscillator frequency is 24.576 MHz, wherein the reproduction frequency is 48 kHz, and wherein the direct frequency divider is implemented in order to implement a division ratio of 512.
