Abstract: A server (1) transmits playlists, each playlist including a description of content acquisition information, and playlist configuration data represented between playlists in numerical values. A terminal device (2) receives playlists and playlist configuration data from the server (1), and for a reproduction of content, changes a playlist to be used in accordance with playlist configuration data to reproduce a content of playlist after change. This allows the terminal device (2) to reproduce content in accordance with a state of mind a user may have, based on the playlist configuration data.

Abstract: When a main category change command is received, a main category change section refers to a category information storage section to change setting from a main category under current setting to another main category according to a predetermined order. After completing the main category change processing, a sub category change section refers to the category information storage section to select one sub category from among sub categories belonging to the newly set main category by use of random numbers. An image data generation section reads displayed information corresponding to the set main category and corresponding to the set sub category from a main-category expression-information storage section and a sub-category expression-information storage section, and generates image data according to the read displayed information.

Abstract: A bibliographic-information impression word is generated from a bibliographic information segment about selected one of music pieces. An acoustic feature quantity of an audio signal representing the selected music piece is calculated. A feature-quantity impression word is generated from the calculated acoustic feature quantity. A degree of conformity between the bibliographic-information impression word and the feature-quantity impression word is determined. Both the bibliographic-information impression word and the feature-quantity impression word are selected as final impression words when the determined conformity degree is greater than a predetermined threshold value. One is selected from the bibliographic-information impression word and the feature-quantity impression word as a final impression word when the determined conformity degree is not greater than the predetermined threshold value.

Abstract: A commodity sales data processing apparatus including a display unit configured to display various kinds of information includes an angle-of-field setting unit configured to set an angle of field of a display screen of the display unit to a first angle of field or a second angle of field narrower than the first angle of field. An angle-of-field control section of the commodity sales data processing apparatus causes the angle-of-field setting unit to operate according to a state of use of the commodity sales data processing apparatus and set the angle of field of the display screen of the display unit to the first angle of field or the second angle of field.

Abstract: Impression words express impressions about music pieces and are separated into groups called impression axes. Impression words in each of the impression axes have meanings mutually related with each other. There is a correspondence among the impression words, the impression axes, and the music pieces. One is designated among the impression axes. One is designated among the impression words. A music piece corresponding to the designated impression axis and the designated impression word is played back. Commands are generated which constitute questionnaire choice information about the played-back music piece. A user is enabled to choose one from the generated commands. An impression axis and an impression word corresponding to the command chosen by the user are obtained. A music piece corresponding to the obtained impression axis and the obtained impression word is played back.
