Patent number: 7899830Abstract: A music reproducing apparatus stores, in a storage device, playlist data that defines an order in which a plurality of music data sets are reproduced, displays the playlist data on a display unit, and reproduces music items in the order defined by the playlist data. The playlist data is formed of a plurality of item data sets each corresponding to a music data set. If a user defines an item data set corresponding to a music data set as one to be reproduced, the defined item is provided with a reproduction mark of “check” and displayed with the reproduction mark on the display unit. On the display unit there is also displayed a total reproduction time D13 in which the reproduction time of music data sets defined as those to be reproduced is summed. Furthermore, item data sets for music data sets that are defined as those to be reproduced but are not stored in the storage device are provided with an irreproducibility mark of “???” and displayed with the irreproducibility mark on the display unit.Type: GrantFiled: January 11, 2006Date of Patent: March 1, 2011Assignee: Yamaha CorporationInventors: Takeshi Komano, Hiroki Nakazono, Shigehiko Mizuno

Publication number: 20080060501Abstract: In a storage section, there are stored a plurality of music data sets of a given first format. Reproduction definition information defines reproducing order of a group of desired music data sets among the plurality of music data sets stored in the storage section. On the basis of the reproduction definition information, the music data sets of the first format defined by the reproduction definition information are read out from the storage section and automatically supplied as objects to be converted into a second format different from the first format. Then, the supplied music data sets of the first format are converted into music data of the second format. In this way, the music data sets of the first format can be readily converted collectively into music data of the second format.Type: ApplicationFiled: October 29, 2007Publication date: March 13, 2008Applicant: Yamaha CorporationInventor: Hiroki Nakazono
