Abstract

The present disclosure provides a display method, including: receiving a task list, the task list includes at least one display task, and the display task includes identification information of a video resource corresponding to the display task; displaying the video resource defined by a first target task according to the first target task, where the first target task is a display task, in which the identification information of the display terminal serving as a host is the same as that of a current display terminal; and sending a display trigger signal to a display terminal serving as a slave in the first target task, where the display trigger signal is for controlling the display terminal receiving the display trigger signal to display the video resource defined by the first target task. The present disclosure further provides a display control method, a display terminal, a server and a display system.

First claim

The invention claimed is:

1. A display method, comprising:
receiving a task list, wherein the task list comprises at least one display task, the display task comprises identification information of a video resource corresponding to the display task, a start time of the display task and type information of the display task, the type of the display task comprises splicing displaying, the task list further comprises identification information of a display terminal serving as a host in the display task with the type of splicing displaying and identification information of a display terminal serving as a slave in the display task with the type of splicing displaying, and the display terminal serving as the host and the display terminal serving as the slave in the same display task belong to a same spliced screen;
displaying the video resource defined by a first target task according to the first target task, wherein the first target task is a display task, in which identification information of the display terminal serving as the host is the same as that of a current display terminal, in all display tasks of the task list;
sending a display trigger signal to the display terminal serving as the slave in the first target task, wherein the display trigger signal is used for controlling the display terminal receiving the display trigger signal to display the video resource defined by the first target task; and
after sending the display trigger signal to the display terminal serving as the slave in the first target task, periodically sending synchronization information to the display terminal serving as the slave in the first target task so as to control the display terminal serving as the slave to display synchronously with the current display terminal, wherein a period of sending the synchronization information is less than a predetermined time interval, and the synchronization information includes progress information of displaying of the current display terminal.

2. The display method according to claim 1 , wherein the display terminals in the same spliced screen form a local area network, and during sending the display trigger signal to the display terminal serving as the slave in the display task defined by the first target task, the display trigger signal is broadcast in the local area network.

3. The display method according to claim 1 , further comprising:
after receiving the task list, downloading and storing the video resource, to be displayed, defined by the task list, wherein different video resources have different identification information, wherein the task list is a task list sent by a server, and during downloading and storing the video resource, to be displayed, defined by the task list, the video resource to be displayed is downloaded from the server through Internet.

4. The display method according to claim 1 , wherein the type of the display task further includes stand-alone displaying, the display method further comprising:
displaying the video resource corresponding to the display task defined by a second target task according to the second target task, wherein the second target task is a display task with the type of stand-alone displaying in the task list received by the current display terminal.

5. The display method according to claim 1 , wherein the information carried by the task list further includes a validity period of each display task, and the display method further comprises:
after the display task is executed, judging whether the display task is in the validity period;
in response to that the display task is within the validity period, repeatedly executing the display task.

6. The display method according to claim 1 , further comprising:
in response to the display trigger signal sent by another display terminal, displaying the video resource corresponding to the display task defined by the task list corresponding to the received display trigger signal.

7. A display terminal, comprising:
one or more first processors;
a first storage module configured to store an executable program that, when called, causes the one or more first processors to perform the display method of claim 1 ;
a first I/O interface coupled between the first processor and the first storage module so as to realize information interaction between the first processor and the first storage module.

8. A spliced screen, comprising a plurality of display terminals each being the display terminal of claim 7 .

9. A display method, comprising:
in response to a display trigger signal sent by a display terminal serving as a host in a display task, displaying a video resource defined by the display trigger signal, wherein a current display terminal and the display terminal serving as the host belong to a same spliced screen; and
in response to synchronization information periodically sent by the display terminal serving as the host in the display task, displaying the video resource, currently being displayed, in synchronization with the display terminal serving as the host, wherein the synchronization information includes a displaying progress of the display terminal serving as the host displaying the video resource, and during displaying the video resource, currently being displayed, in synchronization with the display terminal serving as the host, adjusting the displaying progress to be the same as that of the display terminal serving as the host.

10. The display method according to claim 9 , further comprising:
receiving a task list, wherein the task list comprises at least one display task, the display task comprises identification information of a video resource corresponding to the display task, a start time of the display task and type information of the display task, the type of the display task comprises splicing displaying, the task list further comprises identification information of the display terminal serving as the host in the display task with the type of splicing displaying and identification information of a display terminal serving as a slave in the display task with the type of splicing displaying, and the display terminal serving as the host and the display terminal serving as the slave belong to a same spliced screen.

11. The display method according to claim 10 , further comprising:
after receiving the task list, downloading the video resource according to the task list.

12. The display method according to claim 10 , wherein the type of the display task further comprises stand-alone displaying, the display method further comprising:
displaying the video resource corresponding to the display task defined by a third target task according to the third target task, wherein the third target task is a display task with the type of stand-alone displaying in the task list received by the current display terminal.
