Detailed ways

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in various forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concepts of the example embodiments. To those skilled in the art. The described features, structures or characteristics may be combined in any suitable manner in one or more embodiments.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings represent the same or similar parts, and thus their repeated description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and/or processor devices and/or microcontroller devices.

This example implementation first provides an image display method under high latency based on VGTP. Referring to what is shown in Figure 1, the method may include:

Step S101: If the actual frames received by the zero terminal according to the VGTP protocol are continuous, and the number of actual frames received within the first preset time is less than the number of target frames, then the actual frames are Perform inter-frame caching within a second preset time so that the number of cached actual frames reaches the number of target frames, and decode the cached actual frames within the first preset time, to display its corresponding screen.

Step S102: If the actual frame received by the zero terminal according to the VGTP protocol is discontinuous, insert the received actual frame within the first preset time so that the The number of actual frames is completed to be consistent with the number of target frames, and the completed actual frames are decoded to display corresponding pictures.

Through the above method, when the actual frames transmitted to the zero terminal are continuous and the actual frames received within the first preset time are less than the target frame, the actual frames are inter-frame cached so that the number of cached actual frames reaches The number of target frames, and the corresponding screen is displayed; when the actual frames transmitted to the zero terminal are discontinuous, the actual frames are interpolated to make the number of actual frames consistent with the number of target frames, and the corresponding picture. This disclosure solves problems such as stuck, blur, and faults that occur when displaying images of the VGTP protocol, and achieves normal display of images under high latency.

In the following, each step of the above method in this exemplary embodiment will be described in more detail with reference to FIG. 1 .

In step S101, if the actual frames received by the zero terminal according to the VGTP protocol are continuous, and the number of actual frames received within the first preset time is less than the number of target frames, then the actual frames will be Inter-frame caching is performed within the second preset time so that the number of cached actual frames reaches the number of target frames, and the cached actual frames are cached within the first preset time. Decode to display its corresponding picture.

What needs to be understood is that the virtual machine generally encodes the actual frame, and then sends the encoded actual frame to the zero terminal. The zero terminal receives the encoded actual frame and decodes it, so that the decoded actual frame is displayed on the zero terminal. terminal. However, when the communication delay between the virtual machine and the zero terminal is large, the VGTP protocol transmission can be divided into the following two situations when the zero terminal is displayed:

1) The actual frames transmitted from the virtual machine to the zero terminal are continuous, but the delay is large, and there is no frame loss in the actual frames;

2) The actual frames transmitted from the virtual machine to the zero terminal are discontinuous, and there are frame drops, resulting in discontinuous pictures when the zero terminal is decoded.

When the actual frames transmitted by the virtual machine to the zero terminal are continuous and the number of actual frames received by the zero terminal within the first preset time is less than the number of target frames, that is, the zero terminal receives within the first preset time There is a delay in the target frame, causing the zero terminal to only receive the actual frame within the first preset time. Therefore, inter-frame buffering of the actual frame is required, specifically, inter-frame buffering of the actual frame within the second preset time. , so that the number of actual frames after inter-frame buffering reaches the number of target frames within the first preset time, and then the zero terminal decodes the actual frames after inter-frame buffering within the first preset time and displays the decoded The picture corresponding to the actual frame after inter-frame buffering. The first preset time and the second preset time are set according to the actual situation, and the present disclosure does not limit this. The target frame is a received frame set by the zero terminal within the first preset time. The number of actual frames and the number of target frames can be set according to actual conditions, and this disclosure does not limit this.

In an example, when the first preset time is 1S, the target frame is 60 frames and the actual frame is 30 frames. At this time, an inter-frame buffer is set for 1.5s and the picture of the previous second is displayed with a delay of 0.5s. This It can effectively solve the problem of insufficient picture frame rate and lagging.

In step S102, if the actual frame received by the zero terminal according to the VGTP protocol is discontinuous, the actual frame received is interpolated within the first preset time, so that the actual frame will be The number of actual frames is completed to be consistent with the number of target frames, and the completed actual frames are decoded to display corresponding pictures.

What needs to be understood is that when the actual frames transmitted by the virtual machine to the zero terminal are discontinuous, the actual frames need to be interpolated to make the number of actual frames consistent with the number of target frames, and then supplemented on the zero terminal. The completed actual frame is decoded and the picture corresponding to the completed actual frame is displayed.

It also needs to be understood that when the actual frames are interpolated so that the number of actual frames is consistent with the number of target frames, there are two situations. One is that the zero terminal receives it within the first preset time. The actual frames are only I frames and no P frames. The other is that the actual frames of the zero terminal within the first preset time are only P frames and no I frames. Actual frames need to be interpolated and completed according to the situation. The specific method of interpolating frame completion for actual frames is explained in the following embodiments, and will not be described again here.

In one embodiment, if the actual frames received by the zero terminal according to the VGTP protocol are discontinuous, frames are inserted into the actual frames received within the first preset time. , so that the number of actual frames is completed to be consistent with the number of target frames, and the completed actual frames are decoded to display their corresponding pictures, including:

If the actual frame received by the zero terminal within the first preset time is only an I frame and no P frame, the P frame is inserted into the actual frame so that the actual frame is The number is completed to be consistent with the number of the target frames, and the completed actual frames are decoded to display their corresponding pictures.

It should be understood that when there are only I frames and no P frames among the actual frames received by the zero terminal within the first preset time, in this case, when interpolating the actual frames, only the actual frames need to be inserted. Just insert P frames into the frame. After inserting the actual frame, complete the number of actual frames to be consistent with the number of target frames, and then decode the completed actual frames on the zero terminal to display the decoding completion. The picture corresponding to the actual frame after.

In an example, when the first preset time is 1s and the target frame is 60 frames, the actual frames transmitted for 1s are only I frames and no P frames. At this time, frame interpolation can be used to complete the 60 frames, and then Displayed on the zero terminal (that is, the monitor).

In one embodiment, if the actual frames received by the zero terminal according to the VGTP protocol are discontinuous, frames are inserted into the actual frames received within the first preset time, so as to Completing the number of actual frames to be consistent with the number of target frames, and decoding the completed actual frames to display their corresponding pictures, including:

If the actual frame received by the zero terminal within the first preset time is only the P frame and no I frame, then insert the I frame into the actual frame, and then insert all the frames. The P frame is configured so that the number of actual frames is completed to be consistent with the number of target frames, and the completed actual frames are decoded to display their corresponding pictures.

What needs to be understood is that when there are only P frames and no I frames among the actual frames received by the zero terminal within the first preset time, the picture will not be clear at this time. In this case, you need to immediately report to the virtual machine Request an I frame so that the virtual machine sends the I frame to the zero terminal, i.e. interpolates the actual frame. That is to say, you only need to insert an I frame into the actual frame to complete the picture, and then insert a P frame to complete it to the target frame, so as to interpolate the actual frame so that the number of actual frames is completed to the same as the target frame. The numbers are consistent, and then the completed actual frame is decoded on the zero terminal to display the picture corresponding to the decoded and completed actual frame.

In an example, when the first preset time is 1s and the target frame is 60 frames, only P frames and no I frames are transmitted within 1 second. At this time, the picture will not be clear. At this time, you need to immediately request the virtual machine to transmit I frames. frames to complete the picture, and then insert P frames to complete 60 frames, and then display them on the zero terminal (that is, the monitor).

It should be noted that although the various steps of the method in the present disclosure are described in a specific order in the drawings, this does not require or imply that these steps must be performed in this specific order, or that all of the steps shown must be performed. Achieve desired results. Additionally or alternatively, certain steps may be omitted, multiple steps may be combined into one step for execution, and/or one step may be decomposed into multiple steps for execution, etc. Additionally, it is also readily understood that these steps may be performed synchronously or asynchronously, for example, in multiple modules/processes/threads.

Among them, the cache module 201 is used to cache all the actual frames received by the zero terminal according to the VGTP protocol if they are continuous and the number of actual frames received within the first preset time is less than the number of target frames. The actual frames are inter-frame cached within the second preset time, so that the number of cached actual frames reaches the number of the target frames, and the cached said frames are cached within the first preset time. The actual frame is decoded to display its corresponding picture.

The frame insertion module 202 is configured to interpolate frames within the first preset time if the actual frames received by the zero terminal according to the VGTP protocol are discontinuous, so as to The number of actual frames is completed to be consistent with the number of target frames, and the completed actual frames are decoded to display corresponding pictures.

In one embodiment, the frame insertion module 202 includes:

The first frame insertion submodule is used to insert the P frame into the actual frame if the actual frame received by the zero terminal within the first preset time is only an I frame and no P frame. , so that the number of actual frames is completed to be consistent with the number of target frames, and the completed actual frames are decoded to display their corresponding pictures.
