Information browser, method of controlling same, and program

Abstract

A meta-information-read unit, a display-cache unit, a pre-reading-cache unit, a display-state-management unit, an operation-input unit, a meta-information-pre-reading unit, and an input-operation-determination unit are provided. The meta-information-pre-reading unit changes a pre-reading condition and pre-reads meta information on the basis of a result of determination made by the input-operation-determination unit and display-state-management information managed by the display-state-management unit.

1 . (canceled) 
     
     
         2 . An information browser comprising:
 a meta-information-read unit configured to read meta information included in contents;   a display-storage unit configured to store the meta information read by the meta-information-read unit for display;   a display unit configured to generate a display-screen (image) by using the meta-information stored by the display-storage unit;   a display-state-management unit configured to manage a state of the display-screen image generated by the display unit;   an operation input unit configured to perform a plurality of different input operations;   a generating unit configured to generate pre-reading conditions each corresponding to each of the plurality of different input operations associated with the change in display-screen (image) of the displayed display screen (image) based on display-state-management information managed by the display-state-management unit;   a meta-information-pre-reading unit configured to pre-read the meta information by using the meta-information-read unit based on the pre-read condition generated by the generating unit; and   a pre-reading-storage unit configured to store the meta information pre-read by the meta-information-pre-reading unit to a plurality of pre-reading-storage sections.   
     
     
         3 . The information browser according to  claim 2 , further comprising:
 an input-operation-determination unit configured to determine the input operation performed by the operation input unit, wherein the meta-information-pre-reading unit changes the pre-reading condition on the basis of the display-state-management information and a result of the determination made by the input-operation-determination unit.   
     
     
         4 . The information browser according to  claim 2 , wherein the contents is a plurality of contents, and wherein the plurality of input operations is an operation relating to the sorting order for displaying the plurality of contents by the display unit. 
     
     
         5 . The information browser according to  claim 2 , wherein the operation relating to the sorting order includes at least a shift, a focus, or a sort of the contents. 
     
     
         6 . The information browser according to  claim 2 ,
 wherein the pre-reading-storage section is provided for each of information items included in the display-state-management information, where each of the information items can be input through the input operation,   wherein the meta-information-pre-reading unit reads the meta information for every input operation that can be performed, and   wherein the pre-reading-storage unit stores the meta information read for each of the input operations that can be performed in each of the plurality of pre-reading-storage sections.   
     
     
         7 . The information browser according to  claim 3 , wherein the input-information-determination unit determines whether or not a same input operation is continuously performed. 
     
     
         8 . The information browser according to  claim 7 , wherein when the input-operation-determination unit determines that the continuous same input is performed, the meta-information-pre-reading unit assigns priority to meta-information relating to the continuous same input operation and reads the image information to which the priority is assigned. 
     
     
         9 . The information browser according to  claim 7 , wherein when the input-operation-determination unit determines that the continuous same input is performed, the pre-reading-storage unit appropriates part of and/or all of the plurality of pre-reading-storage sections to a storage section configured to store the meta information relating to the continuous same input operation. 
     
     
         10 . The information browser according to  claim 7 , wherein when the input-operation-determination unit determines that the continuous same input operation is performed, the number of at least one piece of meta information read by the meta-information-pre-reading unit is changed. 
     
     
         11 . The information browser according to  claim 7 , wherein when the input-operation-determination unit determines that the continuous same input operation is performed, an item of at least one piece of meta information read by the meta-information-pre-reading unit is changed. 
     
     
         12 . A method of controlling an information browser, the method comprising:
 reading meta information included in contents;   storing the read meta information for display;   generating a display screen (image) by using the stored meta information;   managing a state of the generated display-screen (image) by a display-state-management unit;   performing a plurality of different input operations, by the operation input unit;   generating pre-reading conditions each corresponding to each of the plurality of different input operation associated with the change in display-screen (image) of the displayed display screen (image) based on display-state-management information managed by the display-state-management unit;   
       pre-reading the meta information by using the meta-information-read unit based on the generated pre-read condition; and
 storing the pre-read meta information to a plurality of pre-reading-storage sections. 
 
     
     
         13 . A non-transitory computer readable storage medium storing a program allowing a computer to execute the method according to  claim 12 .
