<P>PROBLEM TO BE SOLVED: To use music playing data embedded as digital watermark information as data for automatically driving an electronic music device linked with an on-air program. <P>SOLUTION: Music playing data embedded as digital watermark information is extracted from a broadcast content including an image and/or musical sound data. The music playing data is comprised of a plurality of events generated in discrete time and embedded in the broadcast content as the digital watermark information by linking generation time of each event with a temporal position of the image and/or musical sound data. A control is executed to drive at least one of a sound source, a playing operation element, and an indicator so as to be synchronized with the image and/or musical sound data running when broadcasting the broadcast content according to the extracted music playing data. In this way, the electronic music device can be easily operated linked with an on-air program without regard to a broadcast specification/form or the like to be used especially, so that it has high versatility and is useful. <P>COPYRIGHT: (C)2008,JPO&INPIT |
