Abstract
An apparatus and method for sharing data between a cloud server and at last one terminal are provided. The method includes displaying, when a data type is selected on a setting menu screen of a cloud service, meta information of real data corresponding to the selected data type, the meta information being downloaded from a server, downloading, when a piece of meta information is selected, the real data corresponding to the selected piece of meta information from the server, and deleting, when the downloaded real data is consumed completely, the consumed real data.
Claims18
A data sharing method of a terminal, the method comprising:
- displaying, when a data type is selected on a setting menu screen of a cloud service, meta information of real data corresponding to the selected data type, the meta information being downloaded from a server;
- downloading, when a piece of meta information is selected, the real data corresponding to the selected piece of meta information from the server;
- deleting, when the downloaded real data is consumed completely, the consumed real data if a meta information mode is set to a meta only on mode;
- and
- storing the downloaded real data after being consumed if the meta information mode is set to a meta only off mode,
- wherein, in the meta only on mode, the downloaded real data is stored in a cache memory temporally while the downloaded real data is being used,
- wherein the meta only off mode is switched to the meta only on mode based on a first threshold value, and
- wherein the meta only on mode is switched to the meta only off mode based on a second threshold value, and the first threshold value is greater than the second threshold value.

A data sharing method of a terminal, the method comprising:
- configuring data types and a meta information mode for use in a cloud service;
- operating, when the meta information mode is set to a meta only on mode, in the meta only on mode;
- and
- operating, when the meta information mode is set to a meta only off mode, in the meta only off mode,
- wherein operating in the meta only on mode comprises:
- displaying, when the meta information mode is set to a meta only on mode, meta information corresponding to data corresponding to a selected data type,
- downloading, when a piece of meta information is selected, the data corresponding to the selected piece of meta information from a server,
- deleting the downloaded data after being consumed,
- wherein operating in the meta only off mode comprises:
- displaying, when the meta information mode is set to a meta only off mode, the meta information corresponding to the data corresponding to the selected data type,
- downloading, when a piece of meta information is selected, the data corresponding to the selected meta information from the server, and
- storing the downloaded data after being consumed,
- wherein, in the meta only on mode, the downloaded data is stored in a cache memory of the terminal temporally while the downloaded data is being used
- wherein the meta only off mode is switched to the meta only on mode based on a first threshold value, and
- wherein the meta only on mode is switched to the meta only off mode based on a second threshold value, and the first threshold value is greater than the second threshold value.

A data sharing method of a terminal, the method comprising:
- downloading and storing meta information of data corresponding to a selected data type for cloud service from a server in an initial synchronization process;
- displaying, when the data type is selected, the meta information of the data corresponding to the selected data type;
- analyzing, when a piece of the meta information is selected, used memory space;
- switching, when the used memory space is greater than a threshold value, from a meta only off mode to a meta only on mode to process the data in the meta only on mode;
- and
- maintaining, when the used memory space is equal to or less than the threshold value, the meta only off mode to process the data in the meta only off mode,
- wherein the meta only off mode synchronizes both the meta information and the corresponding data with copies saved in the server while the meta only on mode synchronizes only the meta information with copies saved in the server, the data corresponding to the meta information being processed in a cache memory and then deleted in the meta only on mode,
- wherein, in the meta only on mode, the data corresponding to the meta information is stored in the cache memory of the terminal temporally while the real data is being used,
- wherein the meta only off mode is switched to the meta only on mode based on a first threshold value, and
- wherein the meta only on mode is switched to the meta only off mode based on a second threshold value, and the first threshold value is greater than the second threshold value.

The data sharing method of claimer 15, wherein the data types comprise at least one of picture, video, music, and document.
A terminal for sharing data with a server, the terminal comprising:
- a transceiver configured to communicate data and meta information representing the data with the server through an Internet Protocol (IP) network;
- a memory having a cache region configured to store the data temporarily and a cloud region configured to store cloud data;
- an input unit configured to receive an input for setting a meta information mode to a meta only on mode or a meta only off mode;
- a display configured to display the cloud data in one of the meta only on mode or the meta only off mode;
- and
- at least one processor configured to:
- control the terminal in the meta only on mode to:
- display, when the meta information mode is set to a meta only on mode, meta information corresponding to data corresponding to a selected data type,
- download, when a piece of meta information is selected, the data corresponding to the selected piece of meta information from a server, and
- delete the downloaded data after being consumed, and control the terminal in the meta only off mode to:
- display, when the meta information mode is set to a meta only off mode, the meta information corresponding to the data corresponding to the selected data type,
- download, when a piece of meta information is selected, the data corresponding to the selected piece of meta information from the server, and
- store the downloaded data after being consumed,
- wherein, in the meta only on mode, the downloaded data is stored in a cache memory of the terminal temporally while the downloaded data is being used,
- wherein the meta only off mode is switched to the meta only on mode based on a first threshold value, and
- wherein the meta only on mode is switched to the meta only off mode based on a second threshold value, and the first threshold value is greater than the second threshold value.
