As shown in fig. 3, a video transmission method provided in an embodiment of the present application includes the following steps.
S101, the MEC server receives first video data shot by the camera through the base station.
Wherein, MEC server passes through the cable with the base station and connects. Illustratively, the cable includes: optical cables and electric cables.
When the camera is a non-panoramic camera, the first video data is non-panoramic video data.
When the camera is a panoramic camera, the first video data comprises panoramic video data and/or non-panoramic video data. The non-panoramic video data refers to data of one visual angle shot by one camera of the panoramic camera. The panoramic video data is video data of a 360-degree view angle formed by video data of different view angles shot by a plurality of cameras of the panoramic camera.
It is understood that, in practical applications, the first video data shot by the panoramic camera includes video data of a plurality of view angles.
Optionally, after receiving the first video data, the MEC server stores the first video data.
S102, the MEC server receives a video request message sent by the live broadcast management platform.
The video request message is used for indicating the first terminal to request the second video data. The second video data is part or all of the first video data.
Illustratively, in a case where the first video data is panoramic video data, the second video data is panoramic video data. In a case where the first video data is non-panoramic video data, the second video data is non-panoramic video data.
Optionally, the video request message includes: a terminal identification and a video data identification. Wherein, the terminal identification is: and the terminal identification supporting the playing of the panoramic video data or the terminal identification not supporting the playing of the panoramic video data. The video data identification includes: a panoramic video data identification or a non-panoramic video data identification.
Optionally, the video request message further includes: a video period message. The second video data may also be video clip data when the video request message comprises a video period message.
Illustratively, when the user watches the sports event live broadcast by using the terminal, the user does not see the video 10 min 01 s to 15 min 30 s after the start of the game, the video time period is 10 min 01 s to 15 min 30 s, and the second video data is the video clip of 10 min 01 s to 15 min 30 s in the first video data.
It is understood that the MEC server may perform the video playback function according to the video period. Therefore, the user can select a video period to watch the video when the user overlooks the video or wants to watch a certain video segment again.
S103, the MEC server sends second video data to the first terminal through the base station according to the video request message.
In case one, if the video request message includes a terminal identifier supporting playing of panoramic video data and a panoramic video data identifier, the MEC server sends the panoramic video data to the terminal supporting playing of the panoramic video data through the base station according to the video request message.
And in the second situation, if the video request message comprises a terminal identifier supporting the playing of the panoramic video data and a non-panoramic video data identifier, the MEC server sends the non-panoramic video data to the terminal supporting the playing of the panoramic video data through the base station according to the video request message.
And thirdly, if the video request message comprises a terminal identifier supporting that the panoramic video data is not played and a non-panoramic video data identifier, the MEC server sends the non-panoramic video data to a terminal not supporting that the panoramic video data is played through the base station according to the video request message.
Based on the technical scheme, the MEC server is deployed beside the base station for receiving the video data shot by the camera, and the base station and the MEC server are connected in a cable mode (such as optical fiber), so that a user only needs to receive the video data sent to the terminal by the MEC server through the base station when watching the live video, and does not need to receive the video data sent to the cloud server by the core network and then sent to the terminal by the base station. Based on this, because the distance between MEC server and the base station is less than the distance between core network and the base station for the time that the party of the event transmitted video data to user terminal reduces, has promoted the user and has watched live experience.
Optionally, if the first video data includes video data of multiple views, the second video data is video data of a first view, and the first view is one of the multiple views.
When the first video data comprises video data of a plurality of visual angles, a user can select one visual angle for better watching the video live broadcast. The embodiment shown in fig. 4 will be described with reference to a specific application scenario.
In a live event scene, the party may place non-panoramic cameras at multiple locations (e.g., four directions east, west, south, and north) of the event venue to capture video data from different perspectives. As shown in fig. 4, the non-panoramic camera 21 on the west side of the field may photograph a scene in an area a, which is the video data of the first view angle in the first video data; the non-panoramic camera 22 on the north side of the field may capture a scene in the area b, which is the video data of the second view angle in the first video data; the non-panoramic camera 23 on the east side of the field may photograph a scene in the area c, which is the video data of the third view angle in the first video data; the non-panoramic camera 24 on the south side of the field may photograph a scene within the area d, which is the video data of the fourth view angle in the first video data.
It should be noted that, in the embodiment of the present application, the party at the event may further place a panoramic camera at the center of the event field, so as to capture and generate video data at different viewing angles. In addition, the first video data is generated by shooting through different camera lenses in the panoramic camera, so that the situation that a plurality of non-panoramic cameras are used for shooting videos can be avoided, and the cost is saved.
If the user wants to view the video data of the second viewing angle while viewing the video data of the first viewing angle, the user can select to switch the video data to view the video data of the second viewing angle.
Specifically, the embodiment of the present application provides a video transmission method, so that a terminal can switch video data of different viewing angles. As shown in fig. 5, the method includes the following steps.
S201, the MEC server receives a video switching message sent by the live broadcast management platform.
The video switching message is used for indicating the first terminal to request video data of a second visual angle in the first video data, wherein the second visual angle is different from the first visual angle, and the second visual angle is one of a plurality of visual angles.
S202, the MEC server sends the video data of the second visual angle to the first terminal through the base station according to the video switching message.
Illustratively, when a user watches video data of a first view angle by using a terminal, the MEC server sends the video data of a second view angle to the terminal through the base station according to the video switching message. The user may then view the video data from the second perspective on the terminal.
Based on the technical scheme, when a user wants to switch videos with different viewing angles, the MEC server receives a video switching message sent by the live broadcast management platform, and sends video data of a second viewing angle to the first terminal through the base station according to the video switching message. Therefore, the user can switch and watch the video data with different visual angles on the terminal at will, and the watching experience of the user is improved.
As shown in fig. 6, a video transmission method according to an embodiment of the present application is provided. The method comprises the following steps.
S301, the MEC server generates third video data according to the first video data.
Wherein the resolution of the third video data is less than the resolution of the first video data. Illustratively, the resolution of the first video data is 4K, and the resolution of the third video data is 1080P.
In an embodiment of the present application, the first video data includes: panoramic video data and/or non-panoramic video data. For panoramic video data included in the first video data, the third video data generated by the MEC server is panoramic video data with lower resolution. For the non-panoramic video data included in the first video data, the third video data generated by the MEC server is the non-panoramic video data with lower resolution.
In one possible implementation manner, the MEC server performs frame extraction processing on the first video data to generate third video data.
And S302, the MEC server sends third video data to the cloud server.
And S303, the cloud server stores the third video data.
Based on the above technical solution, in the video transmission method provided in the embodiment of the present application, the MEC server generates the third video data according to the first video data, and the data size of the third video data is small because the resolution of the third video data is low. And further, the MEC server sends third video data to the cloud server; the cloud server sends the third video data to the second terminal, and the sending time of the cloud server to the second terminal is reduced due to the fact that the amount of the third video data is small, so that the time delay of video data transmission is reduced.
Fig. 7 shows a video transmission method according to an embodiment of the present application. The method comprises the following steps.
S401, the MEC server generates third video data according to the first video data.
S402, the MEC server sends third video data to the first terminal through the base station.
Based on the above technical scheme, after the MEC server generates the third video data according to the first video data, the MEC server sends the third video data to the first terminal through the base station. Due to the fact that the resolution of the third video data is low, the data volume of the third video data sent by the MEC server to the first terminal through the base station is small, and the flow consumed by the user for watching the video is reduced. Therefore, the user can select to view the third video data with a small amount of traffic, thereby viewing the video with less traffic.
In the embodiment of the present application, functional modules or functional units may be divided for the MEC server according to the above method example, for example, each functional module or functional unit may be divided corresponding to each function, or two or more functions may be integrated into one processing module. The integrated module may be implemented in a form of hardware, or may be implemented in a form of a software functional module or a functional unit.
