Abstract

An apparatus for processing information, includes a memory storing a plurality of content items different in type and metadata containing time information of the content items, a cache processor for fetching from the memory the content item and the metadata of the content item to be displayed on a display and storing the fetched content item and the metadata thereof on a cache memory, a display controller for displaying on the display the metadata of the content items from the cache memory arranged in accordance with the time information and a selection operator selecting metadata corresponding to a content item desired to be processed, out of the metadata displayed, and a content processor for fetching from the cache memory a content item corresponding to the metadata selected by the selection operator by referencing the cache memory in response to the selected metadata, and for performing a process responsive to the fetched content item.

Claims

1. An apparatus for processing information, comprising:

a memory for storing a plurality of content items different in type and metadata containing time information of the content items;

a cache processor for fetching from the memory the content item and the metadata of the content item to be displayed on a display and storing the fetched content item and the metadata thereof on a cache memory;

a display controller for displaying on the display the metadata of the content items from the cache memory arranged in accordance with the time information and a selection operator selecting metadata corresponding to a content item desired to be processed, out of the metadata displayed; and

a content processor for fetching from the cache memory a content item corresponding to the metadata selected by the selection operator by referencing the cache memory in response to the selected metadata when the selection operator selects the metadata, and for performing a process responsive to the fetched content item.

2. The apparatus according to claim 1, wherein the cache processor updates the cache memory so that the cache memory stores the content item processed by the content processor and the metadata of the content item, content items having time information prior to and subsequent to time indicated by the time information of the processed content item, and corresponding metadata of the content items.

3. The apparatus according to claim 1, further comprising a communication unit for communicating via a predetermined network,

wherein the content item and the metadata thereof to be stored on the cache memory by the cache processor are stored on a communication apparatus connected to the predetermined network, and

wherein the cache processor fetches the content item and the metadata thereof via the communication unit from the communication apparatus connected to the predetermined network.

4. A method of processing information, comprising steps of:

fetching a content item and metadata of the content item to be displayed on a display from a memory storing a plurality of content items different in type and metadata containing time information of the content items;

storing the fetched content item and the metadata thereof on a cache memory;

fetching the metadata of each content item from the cache memory;

displaying on the display the metadata of the content items from the cache memory arranged in accordance with the time information and a selection operator selecting metadata corresponding to a content item desired to be processed, out of the metadata displayed;

fetching from the cache memory a content item corresponding to the metadata selected by the selection operator by referencing the cache memory in response to the selected metadata when the selection operator selects the metadata; and

performing a process responsive to the fetched content item.

5. A computer program for causing a computer to process information, comprising steps of:

fetching a content item and metadata of the content item to be displayed on a display from a memory storing a plurality of content items different in type and metadata containing time information of the content items;

storing the fetched content item and the metadata thereof on a cache memory;

fetching the metadata of each content item from the cache memory;

displaying on the display the metadata of the content items from the cache memory arranged in accordance with the time information and a selection operator selecting metadata corresponding to a content item desired to be processed, out of the metadata displayed;

fetching from the cache memory a content item corresponding to the metadata selected by the selection operator by referencing the cache memory in response to the selected metadata when the selection operator selects the metadata; and

performing a process responsive to the fetched content item.

6. A mobile terminal comprising:

a memory for storing a plurality of content items different in type and metadata containing time information of the content items;

a cache memory for storing a content item and metadata of the content item to be displayed on a display;

a cache processor for fetching from the memory the content item and the metadata of the content item to be displayed on the display and storing the fetched content item and the fetched metadata thereof on the cache memory;

a display controller for displaying on the display the metadata of the content items from the cache memory arranged in accordance with the time information and a selection operator selecting metadata corresponding to a content item desired to be processed, out of the metadata displayed;

an operation unit for shifting the selection operator; and

a content processor for fetching from the cache memory a content item corresponding to the metadata selected by the selection operator by referencing the cache memory in response to the selected metadata when the selection operator shifted by the operation unit selects the metadata, and for performing a process responsive to the fetched content item.
