Detailed ways

The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

As a first aspect of the present disclosure, a method for pushing video resources is provided. The method for pushing video resources is applied to the virtual reality VR master control terminal of a cloud computing center. As shown in FIG. 1, the method for pushing video resources includes:

In step S110, query the mobile edge computing (MEC, Mobile Edge Computing) server accessed by the user terminal that has established a connection with the current VR master terminal;

In step S120, the video resource is pushed to the MEC server.

In this disclosure, the cloud computing center transmits video resources through a 5G network. As shown in Figure 2, the 5G network has multiple MEC servers, and each MEC server has certain computing, storage, and processing capabilities, so that the video resources pushed in the present disclosure can be stored and video rendering can be provided for user terminals.

When the user terminal establishes a connection with the cloud computing center, it needs to register to the cloud computing center and the MEC server at the same time, and establish a connection with the VR master terminal of the cloud computing center. When it is necessary to push video resources, the VR master control terminal in the present disclosure does not directly push the video resources to the user terminal, but in step S110, it is determined through a query that the user terminal that has established a connection with the current VR master control terminal is accessed And in step S120, push the video resource to the MEC server. After the video resource is pushed to the MEC server, the computing power of the MEC server is used to render the video resource to obtain the VR video resource, and then the MEC server transmits the rendered VR video resource to the user terminal.

In the present disclosure, the specific timing of performing step S110 is not particularly limited. For example, after creating a VR service on the VR master terminal, step S110 can be directly performed.

It is also possible to create a VR service at the VR master control terminal and perform step S110 after responding to the user terminal accessing the VR service. When the VR service is a VR multi-party conference, the VR master will provide a conference list to the user terminal that has established a connection with the current VR master. When the user selects and joins a conference, the VR master will only join the conference. The MEC node accessed by the user terminal of the conference pushes the video resource.

It can be seen that, in the present disclosure, only the MEC server accessed by the user terminal that is registered to the cloud computing center and the MEC server at the same time and establishes a connection with the VR master control terminal of the cloud computing center. In some embodiments, when the VR service is a VR multi-party conference, different video resources are also pushed according to different conferences selected by the user terminal, so that the directional push of video resources is realized, thereby enhancing the privacy and privacy in the process of pushing video resources. safety. At the same time, due to the directional push of the above-mentioned video resources, the VR master control terminal does not need to push video resources to every user terminal or every MEC server, thereby reducing bandwidth consumption on the 5G core network.

As described above, in step S120 of the present disclosure, the video resources pushed to the MEC server are unrendered video resources, that is, the cloud computing center does not render the video resources, and the MEC server renders the video resources and transmits them to the user The terminal is no longer transmitted through the backbone network, thereby further reducing the consumption of network bandwidth and computing resources. At the same time, because the user terminal directly obtains video resources from the MEC server, it overcomes the high latency and low reliability caused by multiple links, multiple network elements, and multiple networks when the user terminal interacts with the cloud computing center in the prior art. Sexual issues ensure the quality of VR services.

The video resource push method provided by the present disclosure directs and pushes unrendered video resources to the MEC server accessed by the user terminal, and the MEC server provides video rendering to the user terminal, so that the storage and rendering of video resources are closer to the user terminal, It can reduce the consumption of network bandwidth and computing resources, and reduce the network delay caused by the transmission and rendering of video resources, thereby ensuring the quality of VR services.

In this disclosure, each MEC server can access multiple user terminals. Therefore, when the VR master pushes video resources to a certain MEC server in response to the application of the current user terminal, the MEC server may be The video resource to be pushed already exists in the previous application of the user terminal other than the user terminal. In this publication, before pushing video resources to the MEC server, the MEC server is detected first, so as to avoid unnecessary waste of network bandwidth and computing resources caused by repeated push of video resources. Correspondingly, in addition to the above-mentioned step S110 and step S120, the video resource pushing method, as shown in FIG. 3, before step S120, further includes:

In step S130, it is detected whether there are video resources to be pushed to the user terminal on the MEC server;

If the video resource to be pushed to the user terminal does not exist on the MEC server, step S120 is executed.

It should be noted that, when it is found that there is a video resource to be pushed to the user terminal on the MEC server by performing step S130, the user terminal can directly obtain the video resource from the MEC. At this time, the video resource is pushed The process ends.

In this disclosure, the method for detecting whether there is a video resource to be pushed to the user terminal on the MEC server is not particularly limited, and it can be determined whether there is a video to be pushed to the user terminal on the MEC server. All resource methods belong to the protection scope of this disclosure.

In some embodiments, as shown in FIG. 4, step S130 may include:

In step S131, it is detected whether there are historical video resources on the MEC server;

If the historical video resource exists on the MEC server, step S132 is executed: detecting whether the historical video resource has timed out.

When any one of the following conditions is met, it is determined that the video resource to be pushed to the user terminal does not exist on the MEC server:

The historical video resource does not exist on the MEC server;

The historical video resource exists on the MEC server, and the storage time of the historical video resource on the MEC server exceeds a predetermined time.

For ease of description, "the time that the historical video resource is stored on the MEC server exceeds a predetermined time" may be referred to as "the historical video resource has timed out".

In the present disclosure, there is no special limitation on the determination condition for determining that the historical video resource on the MEC server has timed out. For example, when the time of the historical video resource on the MEC server exceeds 1 min, it is determined that the historical video resource has timed out.

In the actual application of the VR service, the VR master control terminal needs to switch the view FOV according to the business, and then needs to synchronize the FOV of the user terminal accessing the current VR service. Correspondingly, in addition to the above-mentioned steps S110 and S120, the video resource pushing method, as shown in FIG. 5, after step S120, further includes:

In step S140, the FOV information is sent to the cloud computing center server of the cloud computing center.

It should be pointed out that the FOV here refers to the current viewing angle of the object.

In some embodiments, as shown in FIG. 4, the above-mentioned step S140 is performed after step S132. Perform step S131 to find that the historical video resource exists on the MEC server, and then perform S132 to find that the historical video resource on the MEC server has not timed out. At this time, the process of pushing video resources ends, and step S140 can be further performed to synchronize. FOV.

It should be pointed out that the "FOV synchronization information" here refers to the synchronization control information obtained after coordinate conversion is performed according to the received FOV information.

After receiving the FOV synchronization information, the MEC server can process the video when rendering the received video resource, so that the perspective of the VR video resource received by the user terminal can be consistent with the perspective of the VR master. In other words, through the FOV synchronization method, it can be ensured that the viewing angle of the VR video viewed by the user terminal is the same as the viewing angle of the VR master terminal, thereby improving user experience.

In some embodiments where step S220 is performed, the FOV synchronization information is transmitted to the MEC server accessed by the user terminal that has established a connection with the VR master through the communication layer of the cloud computing center.

In step S330, the VR video resource is transmitted to the user terminal.

It should be explained that the "user terminal" here refers to a user terminal that accesses the current MEC server and establishes a connection with the VR master terminal.

In the VR video resource transmission method provided by the present disclosure, the MEC server renders the video resource and transmits it to the user terminal instead of transmitting through the backbone network, thereby further reducing the consumption of network bandwidth and computing resources. At the same time, because the user terminal directly obtains video resources from the MEC server, it overcomes the high latency and low reliability caused by multiple links, multiple network elements, and multiple networks when the user terminal interacts with the cloud computing center in the prior art. Sexual issues ensure the quality of VR services.

In the present disclosure, the FOV synchronization of the user terminal is also performed through the MEC server. Correspondingly, in addition to the above-mentioned step S310 and step S320, the video resource transmission method, as shown in FIG. 8, after step S330, further includes:
