<p><P>PROBLEM TO BE SOLVED: To overcome the problem with a conventional HDMI audio clock transmitting system, wherein a cycle time-stamp value varies, resulting in deteriorated accuracy of the audio clock. <P>SOLUTION: The data transmitting device includes: a clock frequency divider to divide sample clock for data by a given division ratio to generate a clock; a counter to count the clock generated with the clock frequency divider; an averaging unit to average the count values measured with a counting generator; a noise shaper to reduce the number of bits of an average count value acquired with the averaging unit; and a transmitter to transmit a base clock, the count value generated with the noise shaper and the frequency division ratio used by the clock frequency divider. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
