Embodiment 1

[0033] Such as figure 1 As shown, this embodiment provides a multi-terminal synchronous display method, which includes:

[0034] 101. The terminal receives an image drawing instruction synchronously sent by the server to multiple terminals.

[0035] When multiple terminals need to play images synchronously, the server connected to the multiple terminals synchronously sends an instruction to draw an image to the terminal, and the terminal receives the instruction to draw an image to draw an image.

[0036] 102. After receiving the instruction to draw an image, the terminal draws an image at intervals of a first specified period.

[0037] After each terminal receives the instruction to draw an image, it can time synchronously, and draw an image synchronously at intervals of a first specified period, so as to realize synchronous playback of images on multiple terminals. If the image that needs to be displayed synchronously is an image that includes multiple frames, the terminal...

Embodiment 2

[0039] Such as figure 2 As shown, this embodiment provides a multi-terminal synchronous display method, which includes:

[0040] 201. The terminal receives a wake-up instruction synchronously sent by the server to multiple terminals, so as to wake up the terminal.

[0041] 202. After receiving the wake-up instruction, the terminal receives an instruction for drawing a base map sent by the server, and draws a base map according to the instruction for drawing a base map.

[0042] 203. After drawing the base map and receiving the instruction to draw the image, the terminal draws a frame of image on the base map every interval of a first specified period, and after drawing the base map and receiving After receiving the instruction to draw an image, the terminal refreshes the base image at intervals of a second specified period, and the second specified period is greater than or equal to the first specified period.

[0043] For example, in order to play Graphics Interchange Form...

Embodiment 3

[0047] This embodiment provides a terminal that can be applied to Embodiment 1, and the details are as follows.

[0048] Such as image 3 As shown, a terminal, including:

[0049] The receiving unit 301 is configured to receive an image drawing instruction synchronously sent by the server to multiple terminals, and transmit the image drawing instruction to the timing unit 302;

[0050] The timing unit 302 is configured to receive the instruction for drawing the image transmitted by the receiving unit 301, and after receiving the instruction for drawing the image, send the instruction for drawing the image to the drawing unit 303 every time a first specified period is counted;

[0051] The drawing unit 303 is configured to receive the image drawing instruction transmitted by the timing unit 302, and according to the image drawing instruction, the terminal draws an image once.

[0052] The timing unit 302 of each terminal is timed synchronously, and the drawing unit 303 of eac...

Abstract

The embodiment of the invention discloses a multi-terminal synchronous display method which comprises the following steps that: a terminal receiving server transmits an image drawing instruction to multiple terminals synchronously; and after receiving the image drawing instruction, the multiple terminals draw images once at every a first designation period. The invention also provides a corresponding terminal and system. According to the embodiment of the invention, multi-terminal synchronous display is realized, meanwhile signaling interaction between terminals and a server is reduced, network expenses are reduced, and system performance is improved.

Description

technical field [0001] The invention relates to a multi-terminal synchronous display method, terminal and system. Background technique [0002] In the prior art, in order to display animation synchronously on multiple terminals, each terminal needs to report a request for drawing an image to the synchronization server before drawing each frame of image, and the synchronization server will reply to each terminal after receiving all the terminal requests. Drawing instructions, each terminal draws a frame image after receiving the synchronous drawing instruction, and completes the synchronous display. It can be seen that every time each terminal draws a frame image, it needs to perform command interaction with the synchronization server. Therefore, when the number of image frames is large, each terminal needs to perform multiple command interactions with the synchronization server, which increases the network overhead and reduces the system performance.
