Abstract
The present invention relates to a kind of methods of multiple terminals compatibility display, including：Terminal receives the instruction that server synchronizes the drawing image sent to multiple terminals；After receiving the instruction of drawing image, at interval of a first specified period, terminal draws an image.The present invention also provides corresponding terminal and systems.The embodiment of the present invention realizes multiple terminals simultaneous display, while reducing the Signalling exchange of terminal and server, reduces network overhead, improves system performance.
Description
Technical field
The present invention relates to a kind of methods of multiple terminals compatibility display.
Background technology
In the prior art, in order to which in multiple terminal simultaneous display animations, each terminal needs before drawing each frame image
The request of drawing image is reported to sync server, sync server is after receiving all terminal requests, to each terminal replies
It is synchronous to draw instruction, after each terminal receives the instruction for synchronizing and drawing, a frame image is drawn, and complete simultaneous display.It can see
It arrives, each terminal often draws a frame image, is required for carrying out instruction interaction with sync server, therefore, when number of image frames is more
When, each terminal needs to carry out multiple instruction interaction with sync server so that network overhead increases, and reduces system performance.
Invention content
In view of this, the present invention provides a kind of method of multiple terminals compatibility display.
A kind of method of the multiple terminals compatibility display, a kind of multiple terminals synchronous display method, including：Terminal receives service
Device synchronizes the instruction of the drawing image sent to multiple terminals；After the instruction for receiving the drawing image, at interval of one
First specified period, the terminal draw an image.
In the present invention, described image is graphic interchange format GIF images.
In the present invention, further include：Before the instruction that the terminal receives the drawing image, the terminal receives institute
The instruction of the drafting base map of server transmission is stated, and according to the instruction for drawing base map, draws base map；The terminal is drawn
One time image is specially：After drawing base map, the terminal draws a frame image on the base map.
In the present invention, after drawing base map and after the instruction for receiving the drawing image, refer at interval of one second
Fixed cycle, the terminal refresh a base map, and the second specified period was greater than or equal to for the described first specified period.
In the present invention, before the instruction that the terminal receives the drawing image, the terminal receives the service
Device synchronizes the wake-up instruction sent to multiple terminals, to wake up the terminal.
Description of the drawings
By reading the detailed description of hereafter preferred embodiment, various other advantages and benefit are common for this field
Technical staff will become clear.Attached drawing only for the purpose of illustrating preferred embodiments, and is not considered as to the present invention
Limitation.
Fig. 1 is a kind of flow of the method for 1 multiple terminals of embodiment of the present invention compatibility display.
Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Those skilled in the art of the present technique are appreciated that unless expressly stated, singulative " one " used herein, " one
It is a ", " described " and "the" may also comprise plural form.It is to be further understood that is used in the specification of the present invention arranges
It refers to there are the feature, integer, step, operation, element and/or component, but it is not excluded that presence or addition to take leave " comprising "
Other one or more features, integer, step, operation, element, component and/or their group.
As shown in Figure 1, present embodiments providing a kind of multiple terminals synchronous display method comprising：101, terminal receives clothes
Business device synchronizes the instruction of the drawing image sent to multiple terminals.When needing multiple terminals synchronously playing images, connect with multiple terminals
The server connect synchronizes the instruction for sending drawing image to terminal, and terminal receives the instruction of the drawing image, to be drawn
Image.102, after the instruction for receiving the drawing image, at interval of a first specified period, the terminal is drawn primary
Image.Each terminal, can be with time synchronisation, in one first specified week of interval after the instruction for receiving the drawing image
It is phase, synchronous to draw an image, to realize image being played simultaneously in multiple terminals.If desired the image of simultaneous display be comprising
The image of multiframe, then at interval of a first specified period, the terminal can draw a frame image, to realize simultaneous display.
The time in the first specified period can be set as 200 milliseconds.
A kind of method of the multiple terminals compatibility display, a kind of multiple terminals synchronous display method, including：Terminal receives service
Device synchronizes the instruction of the drawing image sent to multiple terminals；After the instruction for receiving the drawing image, at interval of one
First specified period, the terminal draw an image.Described image is graphic interchange format GIF images.
In the present invention, further include：Before the instruction that the terminal receives the drawing image, the terminal receives institute
The instruction of the drafting base map of server transmission is stated, and according to the instruction for drawing base map, draws base map；The terminal is drawn
One time image is specially：After drawing base map, the terminal draws a frame image on the base map.
In the present invention, after drawing base map and after the instruction for receiving the drawing image, refer at interval of one second
Fixed cycle, the terminal refresh a base map, and the second specified period was greater than or equal to for the described first specified period.Described
Before terminal receives the instruction of the drawing image, the terminal receives the server and synchronizes calling out for transmission to multiple terminals
It wakes up and instructs, to wake up the terminal.
Each technical characteristic of embodiment described above can be combined arbitrarily, to keep description succinct, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, it is all considered to be the range of this specification record.
Some exemplary embodiments of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but
It cannot be construed as a limitation to the scope of the present invention.It should be pointed out that for the ordinary skill people of this field
For member, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the present invention's
Protection domain.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
