Embodiment
Here exemplary embodiment will be illustrated in detail, its example is illustrated in the accompanying drawings.Following description is related to
During attached drawing, unless otherwise indicated, the same numbers in different attached drawings represent the same or similar key element.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistent with the disclosure.On the contrary, they be only with it is such as appended
The example of the consistent apparatus and method of some aspects be described in detail in claims, the disclosure.
In some network systems, as shown in Figure 1, including server and terminal device, terminal device passes control instruction
Server is transported to, server response control instruction generation display interface, is transmitted to terminal device by display interface and shows, terminal is set
The standby display interface for only needing to receive and display server is sent, it is not necessary to handle control instruction.That is,
Terminal device includes display module, communication module and a small amount of memory space, it is not necessary to the hardware resource such as processor, data fortune
The processes such as calculation processing are all realized by server, reduce dependence of the terminal device to hardware resource.If terminal device is connected with
Mouse, then server be also required to mouse images being transmitted to terminal device.
Based on the explanation of above application scene, the embodiment of the present disclosure provides a kind of data transmission method, applied to server,
Can be with the server in the network system shown in Fig. 1, as shown in Fig. 2, the data transmission method comprises the following steps：
201st, the mouse event information that receiving terminal apparatus is sent.
The change of mouse event information indication mouse.The change of mouse can include the change of mouse images, the change of position
Change etc..In general, the change of mouse is to caused by the operation of mouse, for example, single left button mouse click, double click is left as user
Key, unit right mouse button, mobile mouse, change of mouse images etc. when and for example program loads.
202nd, mouse present image is determined according to mouse event information.
In one embodiment, mouse present image is determined according to mouse event information, including：Mouse event information is write
Enter system, the corresponding mouse event of triggering mouse event information；Call and perform mouse with the relevant application program of mouse event information
Mark the operation indicated by event information；Mouse present image is determined according to operating result.
For example, as shown in a parts in Fig. 3, mouse event information instruction double left button mouse click, starts some application program,
Then mouse present image should become image when program loads；And for example, as shown in b parts in Fig. 3, the instruction of mouse event information
In blank space a mouse click right button, then mouse present image does not change；And for example, as shown in c parts in Fig. 3, mouse event
Information indication mouse is moved to the body part of word document from blank space, then calls word programs movement mouse position, and will
Mouse present image becomes I-shaped cursor.
When mouse present image the 203rd, is found in cache image, the identity of mouse present image is obtained.
Cache image includes at least one mouse images.Server and terminal device are stored with cache image, if
Mouse present image is found in cache image, then illustrates that terminal device has stored the image, server need not be to end
End equipment sends mouse present image, if not finding mouse present image in cache image, illustrates that terminal device does not have
Have and store the image, server needs to send mouse present image to terminal device.

In one embodiment, this method further includes：Calculate the cryptographic Hash of mouse present image；
In the first application scenarios, the cryptographic Hash of mouse present image is found in stored Hash value list
When, search whether to include mouse present image in cache image.At this time, by the mouse images included in cache image and mouse
Present image is compared, and judges whether include mouse present image in cache image.
In second of application scenarios, the Hash of mouse present image is not found in stored Hash value list
During value, determine not including mouse present image in cache image.
It is smaller to calculate cryptographic Hash operand, can be reduced with whether including mouse present image in preliminary judgement cache image
Operand, improves treatment effeciency.
In one embodiment, the identity (English of mouse present image is obtained：Identity, ID), including：According to
Default mapping, obtain mouse present image identity, it is default mapping be used for indicate at least one mouse images with extremely
Correspondence between the identity of few mouse images.
204th, send mouse to terminal device and show information.
Mouse shows that information includes the identity of mouse present image.
In one embodiment, mouse shows that information further includes the positional information of mouse, the position current for indication mouse
Put.
If it should be noted that not having mouse present image in cache image, server still needs to set to terminal
Standby transmission mouse present image, detailed process are as follows：
In one embodiment, this method further includes：It is mouse when mouse present image is not found in cache image
Mark present image distribution identity；
The identity of mouse present image and mouse present image is sent to terminal device.
Further, in one embodiment, this method further includes：
The mouse present image is stored in cache image, and is stored as the identity mark of mouse present image distribution
Know.
When there is no mouse present image in cache image, mouse present image is sent to terminal device, ensure that scheme
Integrality.
The data transmission method that the embodiment of the present disclosure provides, when mouse present image is included in cache image, server
Mouse present image need not be transmitted to terminal device, it is only necessary to its identity is transmitted, reduces volume of transmitted data,
Encoder complexity is reduced, terminal device can be in the cache image being locally stored according to the identity of mouse present image
Middle acquisition mouse present image is shown solve the problems, such as mouse interim card, hysteresis.

For a kind of data transmission method, applied to server and terminal device, as shown in figure 5, Fig. 5 is one that the embodiment of the present disclosure provides
The interaction figure of kind data transmission method, this method comprise the following steps：
501st, terminal device sends mouse event information to server.
The change of mouse event information indication mouse.
It should be noted that before terminal device sends mouse event information to server, start shooting in terminal device, with clothes
It is engaged in after device connection, server can send initial mouse message to terminal device, and initial mouse message includes mouse initial pictures
And position.Terminal device shows mouse images according to initial mouse message.
502nd, server determines mouse present image according to mouse event information.
Step 503-504 is further included after step 502：
503rd, when server finds mouse present image in cache image, the identity mark of mouse present image is obtained
Know.
504th, server sends mouse to terminal device and shows information.
Mouse shows that information includes the identity of mouse present image and the positional information of mouse.
Alternatively, further include step 505-507 after step 502：
505th, when server does not find mouse present image in cache image, identity is distributed for mouse present image
Mark.
506th, server stores the mouse present image in cache image, and is stored as the distribution of mouse present image
Identity.
507th, server sends mouse to terminal device and shows information.
Herein, which shows that information includes the position of mouse present image, the identity of mouse present image and mouse
Confidence ceases.
After step 504 and 507, this method further includes：
508th, terminal device shows presentation of information mouse present image according to mouse.
If it should be noted that there is no mouse present image in cache image, mouse in terminal device storing step 507
Mark shows the identity of mouse present image and mouse present image that information includes.
