Patent ID: 6970111

Claim:
A system for digital to analog conversion being able to perform a conversion of an incoming digital bit stream without previous knowledge of its sample rate is comprising: a means to measure a number of master clock pulses during at least one frame of the incoming digital bit stream, having inputs and an output, wherein the inputs are said incoming digital bit stream and pulses of a master system clock and the output is an input for a means to calculate an actual sample rate; a means to remove all bits which are not required for the digital to analog conversion from the incoming digital bit stream, having inputs and an output, wherein the inputs are said digital bit stream and said pulses of a master system clock and the output is an input for a means to calculate the actual sample rate; said means to calculate the actual sample rate of the incoming digital bit stream and to add said calculated sample rate to the output of said means to remove bits having inputs and an output, wherein the inputs are the output of said means to remove all bits that are not required for the digital to analog conversion, and the results of said means to measure a number of master clock pulses during at least one frame of said incoming digital bit stream and the output, comprising said calculated sample rate added to the output of said means to remove bits, is an input for a means to convert a digital input stream to analog values; and said means to convert a digital input stream to analog values using the sample rate calculated by said means to calculate said actual sample rate, having an input and an output, wherein the input is the output of said means to calculate the actual sample rate and the output are converted analog values.
