Patent ID: 7181298

Claim:
An information converting method of converting audio information, which comprises a plurality of partial-audio information based on a predetermined record standard in each of which output control information to control a state of the audio information at a time of outputting the audio information to an external portion is included, into transmission information to be transmitted through a data bus based on a predetermined transmission standard, said method comprising: an extracting process of extracting the output control information from each of the partial-audio information; a dividing process of dividing the audio information for a predetermined amount, which is set in advance so as to transmit the transmission information through the data bus, to thereby generate divided-audio information; a generating process of adding the extracted output control information onto the generated divided-audio information to thereby generate an information unit for transmitting the audio information through said data bus; and an outputting process of generating the transmission information by using a plurality of the generated information units and outputting the generated transmission information onto said data bus, wherein the output control information comprises: first output control information to be transmitted through said data bus; and second output control information to be transmitted through said data bus , and wherein said generating process generates the information unit comprising the divided-audio information, the first output control information and either the second output control information or predetermined other information, the first output control information comprises mix control information to perform a channel mix process of the audio information at the time of outputting, and the second output control information comprises frequency identification information indicative of a sampling frequency of the audio information.
