Abstract

An updating display system of a display list and the method thereof are provided. A first version information of the display list at a local end is checked against with a second version information on a server. If they are different, only a modification item file containing a data item to be modified is downloaded from the server. The display list is then modified according to a line number given in the modification item file. The data item in the display list are ordered according to the time tags in the modification item file. This can solve the problems of spending too much time in downloading the display list and an unclear play list. This helps to achieve efficient update and better display.

Claims

1. An updating display method of display lists, comprising the steps of:

storing at least one display list and a first version information corresponding to the display list;

downloading an update information file of the display list with a second version information from a server;

when determining the first version information and the second version information of one of the display lists are different, downloading a modification item file of the corresponding display list from the server, the modification item file including at least one data item, a line number of the data item, and a time tag of the corresponding data item;

editing the display list of different version information according to the line number and the data item;

adjusting the order of the data items in the edited display list according to the time tags; and

displaying the order-adjusted display list.

2. The updating display method of claim 1, wherein the step of determining whether the first version information and the second version information of one of the display lists are different compares a version number/previous update time with a latest version number/update time stored in the update information file of the display list.

3. The updating display method of claim 1, wherein the step of editing the display list of different version information according to the line numbers and the data items writes the data item into the corresponding line number of the display list according to the time tag.

4. The updating display method of claim 1, wherein the step of editing the display list of different version information according to the line numbers and the data items removes the data item from the line number of the display list.

5. The updating display method of claim 1, wherein the step of adjusting the order of the data items in the edited display list according to the time tags copies or moves the data items whose time tags are later than the previous update time to the beginning of the edited display list.

6. An updating display system of display lists, comprising:

a storage module, which stores at least one display list and a first version information thereof;

a communication module, which downloads an update information file of the corresponding display list with a second version information from a server;

a determining module, which determine whether the first version information and the second version information of one of the display lists are the same;

an editing module, which downloads via the communication module a modification item file corresponding to the display list whose the first version information and the second version information are different from the server, the modification item file including at least one data item, a line number of the data item, and a time tag of the data item, and edits the display list according to the line numbers and the data items;

an order adjusting module, which adjusts the order of the data items in the edited display list according to the time tags; and

a display module, which displays the ordered display list.

7. The updating display system of claim 6, wherein the determining module compares a version number/previous update time stored in the storage module with a latest version number/update time stored in the update information file of the display list.

8. The updating display system of claim 6, wherein the editing module writes the data item into the corresponding line number of the display list according to the time tag.

9. The updating display system of claim 6, wherein the editing module removes the data item from the line number of the display list.

10. The updating display system of claim 6, wherein the order adjusting module moves the data items whose time tags are later than the previous update time to the beginning of the edited display list.
