Abstract

A content selection device 1 of the present invention is connected to an audio player storing a content list being a list of tune titles, and to a display displaying a portion of the content list on an OSD screen. A total number identifying section 13 of the content selection device 1 identifies the total number of tunes in the content list. A skip value setting section 15 determines a skip value obtained by multiplying the identified total number of tunes by a predetermined skip rate. In response to the activation of a scroll button 50 on a remote controller 5, a scrolling section 16 identifies a set of tune titles to be displayed on the OSD screen after scrolling the portion of the content list being displayed on the OSD screen by the skip value. An OSD instruction section 11 produces an OSD signal for displaying the identified tune titles on the OSD screen, and sends the produced OSD signal to the display.

a top-of-screen content attribute identifying section, which identifies a top-of-screen content attribute being one of the content attributes listed in the content list that is offset from a content attribute being displayed at a top of the display screen by a distance corresponding to the skip value in the scrolling direction, when a list scroll command including a scrolling direction is received from the input device;

a display attribute specifying section, which specifies a set of content attributes from among the content attributes listed in the content list, the set including a number of content attributes listed in a forward direction in the content list starting from the top-of-screen content attribute, the number of content attributes in the set corresponding to a maximum display number of the display screen;

a display instruction section, which instructs the display device to sequentially display, on the display screen, the set of content attributes identified by the display attribute specifying section, starting from the top-of-screen content attribute;

a cursor moving section, which moves a cursor on the display screen by one content attribute in the cursor moving direction, when a cursor moving command including a cursor moving direction is received from the input device; and

a content attribute selecting section, which selects one of the set of content attributes displayed on the display screen that is being specified by the cursor, when a select command is received from the input device.

2. The content selection device according to claim 1, wherein:

the content list includes a plurality of content numbers, which indicate an order in which the content attributes are sorted; and

the top-of-screen content attribute identifying section, which identifies a content number associated with a content attribute being displayed at a top of the display screen, calculates a content number obtained by adding the skip value to the identified content number, and identifies a content attribute associated with the calculated content number as being the top-of-screen content attribute.

3. The content selection device according to claim 1, wherein the skip value setting section determines the skip value by multiplying the total number of content attributes by a predetermined skip rate.

4. The content selection device according to claim 3, wherein each time a skip value changing command is received from the input device, the skip rate is decreased, and the skip value setting section determines the skip value by multiplying the total number of content attributes by the decreased skip rate.

5. The content selection device according to claim 4, wherein if the skip value obtained by multiplication by the skip rate is smaller than the maximum display number of the display screen, the skip value setting section determines the skip value to be equal to the maximum display number.

6. The content selection device according to claim 4, wherein:

when the skip value changing command is received, the skip value setting section determines a skip value based on Expression 1 below;

skip value=TN×

(P/100)N+1 

 

Exp. 1

where TN is the total number of content attributes, P is a reference skip rate (%), and N is an accumulative number of times the content selection device has received the skip value changing command.

7. The content selection device according to claim 6, further comprising a skip rate setting section, which determines nmax and the reference skip rate P(%) that minimize a value of Expression 3 below, where nmax denotes a maximum number of skip values as defined in Expression 2 below:

n max≦

α

 

 

Exp. 2

(100/P)×

n max+n max+TN/(100/P)n max 

 

Exp. 3

where α

is a predetermined natural number,

wherein the skip value setting section determines the skip value based on the determined reference skip rate P.

8. The content selection device according to claim 1, further comprising a section, which identifies a downward jump destination content attribute being one of the content attributes listed in the content list that is offset from the identified top-of-screen content attribute by a distance corresponding to the skip value in a forward direction of the content list, and identifies an upward jump destination content attribute being one of the content attributes listed in the content list that is offset from the identified top-of-screen content attribute by a distance corresponding to the skip value in a backward direction of the content list,

wherein the display instruction section instructs the display screen to display information regarding the identified downward jump destination content attribute and information regarding the identified upward jump destination content attribute.

9. A content selection device, comprising:

a content storage device, which stores a plurality of content items and a content list being a list of content attributes for identifying the content items;

a display device, which has a display screen for displaying a subset of the content attributes listed in the content list;

a input device, which includes a plurality of push buttons for outputting a plurality of commands according to user operations;
