  The present invention relates to a technique for presenting information related to music to be played back to a user in a music playback device that plays back music.

  In a music playback device that plays back and outputs music, as a technique for presenting information related to the music to be played back to the user, a server that stores music related information such as lyrics and jacket photos of each music is provided and played back on the music playback device A technology is known that searches the server using the artist name, album name, and title name of the music to be played as a search key, acquires the music related information searched, and presents the acquired music related information in parallel with the playback of the music (For example, Patent Document 1).

Japanese Patent Laid-Open No. 2004-117618

  In the music playback apparatus described above, according to the technique for presenting music related information of the music being played back, information relating only to the music being played back is presented, and the music being played back, such as the album or artist of the music being played back Since higher-level information cannot be presented, the range of information that the user can know about the music being played is always limited. On the other hand, if information on all levels such as albums and artists related to the music being played is always presented to the user, information unnecessary for the user at that time is also presented.

Also, according to the technology, the same music related information is always presented when playing the same music, and it is not interesting.
On the other hand, when the user knows the free opinions and impressions of others who listened to the music to be played, the user can obtain new information about the music or have a new viewpoint about the music. It is meaningful because it becomes. Also, if the user can know the free opinions and impressions of others who listened to the music to be reproduced, the experience can be shared with others via the music to be reproduced.

  Therefore, an object of the present invention is to present various levels of information related to the music to be reproduced in a form in which only information of a level significant for the user is presented in the music reproducing device.

  In order to achieve the above object, the present invention displays a list of attribute values of a hierarchy selected by a user on a music playback device that plays back a music for which attribute values in each of a plurality of hierarchies are defined. A song that is obtained by searching for information with the set search word by accessing a selection receiving unit that accepts selection of attribute values from among them, a search word setting unit that sets a search word, and a server that provides an information search function A related information acquisition unit and the music related information display unit for displaying each piece of information acquired by the music related information acquisition unit are provided.

  However, the attribute value of each hierarchy except the lowest hierarchy is related as an upper attribute value of any attribute value of the lower hierarchy, and the search word setting unit is The attribute value lower than the attribute value that received the selection is not included in the search word to be set, the attribute value that the selection receiving unit has received the selection, and each attribute value that is higher than the attribute value that has received the selection Is included in the search word to be set.

  Here, such a music reproducing device includes the plurality of hierarchies among an artist hierarchy whose attribute value is an artist name, an album hierarchy whose attribute value is an album name, and a title hierarchy whose attribute value is a title name. It may include at least two layers.

  According to the music playback devices such as these, for a group of music in an arbitrary hierarchy such as an artist, album, or title selected by the user, information is searched with a search word representing the set, and the searched information is displayed. Can do. Therefore, according to the music reproducing apparatus, it is possible to present various levels of information related to music in a form in which only information of a level significant to the user is presented.

  As described above, according to the present invention, various levels of information related to a piece of music to be played can be presented in a form in which only information of a level that is significant for the user is presented.
