Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
The embodiment of the disclosure provides a terminal control system, as shown in fig. 1, the whole system is composed of a source end and a client end.
The source end comprises an acquisition end and an encoder.
The source end is a server, which includes an acquisition end and an encoder, and the acquisition end is used for acquiring image frames.
The client is a terminal device or a set of system composed of a decoder and a display terminal.
The decoder and the display are illustratively implemented in different devices, such as the decoder being located in a zero terminal and the display being a display.
Based on the system, the present disclosure provides a terminal control method.
The embodiment of the disclosure provides a terminal control method, which is applied to a source end, as shown in fig. 2, and includes the following steps:
101. And collecting the current frame image.
102. And judging whether the current frame image is changed compared with the reference frame image.
By way of example, the methods in this disclosure may rely on the vGTP protocol.
Specifically, the vGTP acquisition end acquires a current frame image, identifies the current frame image and judges whether the current frame image is changed compared with a reference frame image.
103. Generating image frame data corresponding to the current frame image according to the change condition, wherein the image frame data comprises: the coding data of the current frame image and the frame type corresponding to the current frame image.
104. And sending the image frame data to the client so that the client executes corresponding processing strategies according to the image frame data, wherein the processing strategies comprise: and controlling the client to enter a sleep mode, a power saving mode or a reminding mode.
In the present disclosure, different image frame data may be generated based on the change conditions of the current frame image and the reference frame image, so that the client may determine the change condition of the current frame image based on the image frame data, so as to select an appropriate processing policy based on the change condition of the current frame.
The sleep mode, namely the stop of the work of the decoding end and the encoding end, the stop of the work of acquisition, encoding, transmission and decoding, and the sleep. When the user wakes up by people, login information such as a user name, a password and the like is required to be input.
The energy-saving mode means that the client display module does not output data to the display device any more, and the display device is automatically closed after no signal source is input.
Reminding mode-when the source end stops at a frame, the method can control:
(1) Outputting an image of the client;
(2) Encoding program of source end and decoding program of client end: program termination, program dormancy, low power consumption operation of the program:
(3) And printing reminding information.
The terminal control method provided by the embodiment of the disclosure comprises the following steps: collecting a current frame image; judging whether the current frame image is changed compared with the reference frame image; generating image frame data corresponding to the current frame image according to the change condition, wherein the image frame data comprises: the coding data of the current frame image and the frame type corresponding to the current frame image; and sending the image frame data to the client so that the client executes corresponding processing strategies according to the image frame data, wherein the processing strategies comprise: and controlling the client to enter a sleep mode, a power saving mode or a reminding mode. The method comprises the steps that identification judgment of a current frame image can be carried out on the basis of the current frame image and a reference frame image at a source end, so that the situation that a user forgets to turn off display equipment can be accurately identified, intelligent control is carried out, information leakage is effectively avoided, energy is saved, the environment is protected, and the problems of information safety and energy waste caused by forgetting to turn off a screen are solved easily.
For the purposes of information security, energy saving and environmental protection, an identification monitoring module (vanxum Discern Moniter Module, abbreviated as vDMM) can be arranged at the encoding end, and the vDMM needs to classify the decoded data information. In particular, such information generally includes:
(1) Reference frame data: encoding, transmitting and decoding the whole frame image; the third frame type mentioned in the later embodiments;
(2) Pseudo-decoded data: the data is not transmitted per se, and only the decoding position information is marked; the first frame type mentioned in the following embodiments;
(3) Delta data: encoding, transmitting, and decoding only the change region; the second frame type mentioned in the later embodiments.
The vDMM focuses mainly on both (2) and (3) types of data.
In one embodiment, as shown in fig. 3, the step 103 includes the following sub-steps:
1031. if the current frame image is unchanged from the reference frame image, generating first image frame data, wherein the first image frame data comprises: the position information of the current frame image and the first frame type corresponding to the current frame image.
For example, whether each pixel point of the current frame image is identical to the pixel point of the corresponding position of the reference frame image or not may be determined, and if so, it is determined that the current frame image is unchanged from the reference frame image.
Further, if no change occurs compared with the reference frame image, the encoder is informed that the entire frame image is unchanged, and the position information of the current frame image is transmitted to the encoder.
When the whole frame of image is unchanged, the pixel point is unchanged, so that only one basic decoding position information is transmitted, and the image data in the true sense is not contained. During decoding, the pixels at the corresponding positions in the restored reference frame image are copied to finish decoding. The essence is a Pseudo decoding (Pseudo decoding) from which it can be distinguished that the image has not changed.
The reference frame image may be the previous frame image or another image.
1032. If the current frame image is changed compared with the reference frame image, judging the number of pixel points of the current frame image, which is changed compared with the reference frame image.
If each pixel point of the current frame image is not completely identical to the pixel point of the corresponding position of the reference frame image, and the same part of the pixel point of the current frame image and the pixel point of the corresponding position of the reference frame image exceeds a preset threshold (for example, 95%), determining the change amount (change area data is called Delta data) of the current frame image and the reference frame image.
1033. If the number of the pixel points is smaller than the preset threshold value, coding the image of the change area of the current frame image compared with the reference frame image.
1034. Generating second image frame data including: the coded data corresponding to the change area and the second frame type corresponding to the current frame image; the coded data corresponding to the change region further includes: position information of the change area.
If the image is changed compared with the reference frame image, only the region with changed pixel points is transmitted to the coding end, and particularly, when the current frame is changed by a small amount of pixel points compared with the reference frame image, the acquisition end only transmits the image information of the changed region to the coding end, and the information is called Delta data. At this time, the encoding end only encodes the Delta data, but does not encode the whole frame data, so that the workload of the encoding code stream and the decoding end is reduced while the consumption of hardware resources of a source end system is effectively reduced.
Furthermore, when the Delta data transferred is substantially the same, the pixel point changes only in a small amount of area, such as: I. the text editing interface only flashes the cursor II. The time and date change of the lower right corner can judge that the user does not operate at the moment according to the time and date change.
In one implementation, the method further includes:
judging whether the current frame image is a reference frame image or not;
if yes, generating third image frame data, wherein the third image frame data comprises: the coded data of the current frame image and a third frame type corresponding to the current frame image.
In addition, it is necessary to explain that: the acquisition end supporting Delta function only sends the changed regions to the encoder at a time. If the change regions transmitted are the same, then the delta data is the same twice.
The acquisition end supporting Delta function only sends the changed area to the encoder each time, and the acquisition end can be set according to the ratio of the pixel points of the changed area to the pixel points of the whole frame, for example < = 3%, which means that the change tends to be carried out only in a small amount.
If the cursor is flashing (as shown in fig. 4), the cursor is flashing at the same position, and the cursor is recognized at the encoding end, and whether the Delta area is consistent or not is checked.
If it is the time-date transformation in the lower right corner (as shown in fig. 5), it is identified at the encoding end whether the two Delta regions agree.

d5, if feedback information sent by the user is not received in the fourth preset time, controlling the client to enter a sleep mode; wherein the fourth preset time is greater than the third preset time.
The method can firstly enter a reminding mode to remind a user to select to enter a sleep mode or an energy-saving mode;
the energy saving mode may be entered if no user operation is performed within the third preset time T1, which is directly set, and the sleep mode may be entered if no user operation is performed within the fourth preset time T2 (T2 > T1).
Only one of them may be selected, or other defined modes may be used, and the present disclosure is not limited thereto.
Further, the user may set the monitoring time of the vDMM before formally using the product, for example: and I.5 minutes, the sleep mode is automatically entered when no operation is performed, and II.4 minutes, the energy-saving mode is automatically entered when no operation is performed.
The administrator can also perform unified configuration on the server side, set the monitoring time of the vDMM and issue to each client. Specifically, the vDMM Client works at the Client to control dormancy and energy conservation of the local Client; the vDMM Server works on the Server to perform unified configuration, setting and issuing. The unified configuration scheme is directed to clustered steering scenarios.
Specific scenarios to which the present disclosure may be applied are as follows:
scene 1: the user has no operation in 2 minutes before setting up to enter the security and energy-saving mode automatically. After the user leaves work, forgets to turn off the computer and the display device, and the current interface is a text editing page; the vDMM monitors that the decoded data is Delta data at this time and has no change for 2 minutes, and starts the sleep and power saving modes.
Specific:
(1) After the energy-saving mode is started, the client display module does not output data to the display equipment any more, and the display equipment is automatically closed after no signal source is input.
(2) After the sleep mode is started, the decoding end and the encoding end stop working, and the acquisition, encoding, transmission and decoding all stop working and enter the sleep mode. When the user wakes up by people, login information such as a user name, a password and the like is required to be input. Here, it is necessary to explain: the computer itself is not powered off and therefore does not result in the loss of user data information.
Scene 2: the user has set no operation before for 3 minutes to automatically enter the security mode. The user leaves the office for a long time, and the current interface is a static picture; the vDMM monitors the now dummy decoded data and automatically initiates sleep mode without change for 3 minutes.
Specifically, the decoding end and the encoding end stop working, and the acquisition, encoding, transmission and decoding all stop working and enter a sleep mode. When the user wakes up by people, login information such as a user name, a password and the like is required to be input.
In sum, the scheme can effectively solve the problems of information security leakage and power resource waste caused when a user forgets to close the screen; the scheme essentially utilizes the bottom layer information of the self-grinding vGTP protocol to carry out systematic analysis at the encoding end and the decoding end, accurately identifies the frame type, further carries out statistics and control, and finally achieves the purposes of security and energy conservation. That is, in the present disclosure, systematic analysis is performed at the encoding end and the decoding end, so that the situation that the user forgets to turn off the display device is accurately identified, intelligent control is performed, information leakage is effectively avoided, and energy conservation and environmental protection are achieved.
