Thus, the following detailed description of the embodiments of the present application, as provided in the accompanying drawings, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, are intended to be within the scope of the present application.
Referring to fig. 1, fig. 1 is a schematic diagram of an interaction scenario of a video streaming interaction system 10 according to an embodiment of the present application. For example, the video stream interactive system 10 may include a display device 100 and an external device 200 communicatively connected, and further include a first server 300 and a second server 400 communicatively connected to the display device 100.
In the embodiment of the present application, the external device 200 may be, but is not limited to, a smart phone, a personal digital assistant, a tablet computer, a personal computer, a notebook computer, a virtual reality terminal device, an augmented reality terminal device, and the like. In an implementation, one or more external devices 200 may be connected to the display device 100, only one of which is shown in fig. 1. Among other things, the external device 200 may have installed therein a program product for providing services (e.g., fitness services) by the display device 100, for example, an APP or applet for use in a computer or smart phone, etc. related to fitness exercises.
In the embodiment of the present application, the first server 300 and the second server 400 may be a single physical server, or may be a server group formed by a plurality of physical servers for performing different data processing functions. The server set may be centralized or distributed (e.g., the first server 300 and the second server 400 may be distributed systems). In some possible implementations, such as the first server 300 and the second server 400 employing a single physical server, different logical server components may be assigned to the physical servers based on different traffic functions.
It will be appreciated that the video stream interactive system 10 shown in fig. 1 is only one possible example, and that in other possible embodiments, the video stream interactive system 10 may include only a portion of the components shown in fig. 1 or may include other components as well.
The display device provided in the embodiment of the present application is described in the following by way of example with reference to the application scenario shown in fig. 1. First, referring to fig. 2, the embodiment of the present application provides a display device 100, including:
a display device 102;
a first communication component 103 configured to receive a first video play request;
a second communication component 104 configured to receive the first video stream address and/or video stream slice;
at least one processor 101;
a memory 105 coupled to the processors 101, the memory 105 storing readable instructions of the processors 101, at least one of the processors 101 executing the readable instructions to cause at least one of the processors 101 to: receiving, by the first communication component 103, a first video play request; receiving, by the second communication component 104, a first video stream address that matches the first video play request; receiving, by the second communication component 104, a video stream slice matching the first video stream address; the received video stream slices are displayed by the display device 102. The video stream address can be the address of a live video stream in real time, or the address of a prerecorded coach video stored on a server. The user can select whether the video to be played is live video or a pre-recorded coaching video lesson.
In this embodiment, the video stream slices are stored in the second server 400, and the first server 300 presets the slice address index.
In one example, when a user needs to exercise, a first video play request is issued by the external device 200, and the display device 100 receives the first video play request through the first communication component 103. The received first video playing request is fetched by the processor 101 to process the first video playing request by the instruction stored in the memory 105, and the identification information of the exercise video corresponding to the first video playing request is obtained. The display device 100 sends the identification information to the first server 300 through the second communication component 104, and the first server 300 obtains a first video stream address corresponding to the identification information through a slice address index after identifying the identification information; the first video stream address may be an address of all video stream slices corresponding to the identification information, or an address of a part of video stream slices corresponding to the identification information. The display apparatus 100 receives the first video stream address through the second communication component 104 and downloads the video stream slice matching the first video stream address from the second server 400 through the first video stream address, and finally the received video stream slice is displayed to the user by the display device 102. The video stream address can be the address of a live video stream in real time, or the address of a prerecorded coach video stored on a server. The user can select whether the video content to be played is live video or a pre-recorded trainer video lesson through the external device 200.
In one example, when the playing time of the exercise video is preset, the external device 200 or the timing model configured on the display device 100 may send the first video playing request when the playing time is reached, and the subsequent data processing and video stream slice receiving process is the same as the above example.
As can be seen from the above examples, the slice address index does not need to be pre-stored in the memory 105, and the acquisition calculation of the video slice address can be passed to the external server for processing calculation, so that the data security of the slice address index is ensured, meanwhile, the calculation resources of the display device 100 are saved, and the local calculation delay of the display device 100 is reduced.
In one possible implementation, the first communication component 103 is communicatively coupled with the external device 200 via a first communication protocol.
In the embodiment of the present application, the first communication component 103 needs to employ a communication component corresponding to the first communication protocol for receiving the first video playing request.
By way of example, when the display device 100 and the external device 200 are in the same network, such as the internet or a local area network, the first communication protocol may employ a communication protocol such as a TCP/IP protocol or an MQTT protocol based on the TCP/IP protocol family.
For example, when the display device 100 and the external device 200 are not in the same network, the data interaction may be completed by way of near field networking, and at this time, the first communication protocol may be a common communication protocol such as bluetooth, zigbee, NBIoT, or the like.
In one possible implementation, the second communication component 104 is communicatively coupled to the first server 300 via a second communication protocol that is different from the first communication protocol.
In the present embodiment, the second communication component 104 needs to employ a communication component corresponding to a second communication protocol for communicative coupling with the first server 300, where the second communication protocol is different from the first communication protocol.
For example, to ensure data security, the second communication protocol may employ an HTTPS protocol, and the second communication component 104 employs a communication component that needs to be compatible with the HTTPS protocol. In detail, when the display apparatus 100 requests the video stream address from the first server 300 through the second communication component 104, the first server 300 transmits the first video stream address searched from the slice address index to the display apparatus 100 through the HTTPS protocol; the display device 100 receives the first video stream address via the second communication component 104. Wherein the first video stream address is preferably a URL address.
In one possible implementation, the second communication component 104 is communicatively coupled to the second server 400 via a third communication protocol that is different from the first communication protocol and the second communication protocol.
In the present embodiment, the second communication component 104 needs to employ a communication component corresponding to the second communication protocol and the third communication protocol for communicative coupling with the first server 300 and the second server 400. The second communication component 104 may be integrated by using modules corresponding to the second communication protocol and the third communication protocol, or may be a communication component compatible with the second communication protocol and the third communication protocol at the same time.
For example, when the second communication protocol employs HTTPS protocol, the third communication protocol employs HTTP protocol among HLS protocols. In detail, when the display apparatus 100 receives the first video stream address based on the second communication protocol through the second communication component 104, the video stream slice corresponding to the first video stream address is downloaded from the second server 400 based on the third communication protocol through the second communication component 104.
In one possible implementation, at least one of the processors 101 receives, from the first server 300, a first video stream address matching the first video play request through the second communication component 104; at least one of the processors 101 receives a video stream slice matching the first video stream address from the second server 400 via the second communication component 104.
In the embodiment of the present application, when the display device 100 receives the first video stream address through the second communication component 104, the processor 101 receives the first video stream address; when the display device 100 downloads a video stream slice corresponding to the first video stream address from the second server 400 via the second communication component 104, the video stream slice is received by the processor 101.
Illustratively, the first video stream address is generated by the first server 300 and matches the first video play request; the video stream slices are pre-stored in the second server 400, and the processor downloads from the second server 400 according to the first video stream address.
In the embodiment of the application, the first video stream address and the video stream slice are stored by being divided into two servers, so that the calculation which should be completed by the processor 101 can be shared to the servers, and the data security and the calculation efficiency are improved.
