Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

For convenience of understanding, terms referred to in the embodiments of the present application are explained below:

multi-screen interaction: the method is characterized in that a flash internet protocol, a Miracast protocol and the like are used, a series of operations such as transmission, analysis, display and/or control of multimedia contents are carried out among different electronic devices through wireless fidelity (WIFI) network connection, the displayed contents can be shared on the different electronic devices, and the multimedia life of users is enriched.

Screen projection: the method refers to a specific implementation technical means of multi-screen interaction, and the method is used for presenting contents (such as audio, video, pictures, characters and the like) on certain electronic equipment on other electronic equipment, so that the effect of synchronously displaying the same contents among a plurality of pieces of electronic equipment or the effect of displaying the contents of the original electronic equipment through one piece of electronic equipment is realized.

A screen projection source device: refers to an electronic device initiating screen projection, wherein the screen projection source device may be a mobile phone, a tablet computer, or the like.

Screen projection target equipment: the method refers to electronic equipment for displaying screen projection source equipment, and screen projection target equipment can be a mobile phone, a tablet personal computer and the like, and can also be a smart television (smart TV), a projector and the like.

Bullet screen: refers to a commentary subtitle that pops up when viewing a video over a network. In the process of watching videos, the user can watch the barrage published by other users and can also send the barrage, and the sent barrage can also be seen by other users, so that interaction is realized in the process of watching videos.

Uniform resource locator: the URL (uniform Resource locator) describes an address of a Resource on the world wide web in an abstract form of a character string, and a URL uniquely identifies a Resource in the world wide web, and the Resource can be obtained through the corresponding URL. That is, each video resource in the world wide web corresponds to a URL by which the resource can be acquired.

Streaming media: refers to a form of media that streams audio, video, and multimedia files over a network. Compared with the network playing mode of watching after downloading, the streaming media is typically characterized in that continuous audio and video information is compressed and then put on a network server, and a user can watch while downloading without waiting for the whole file to be downloaded. Due to the superiority of the streaming media technology, the technology is widely applied to video-on-demand, video conference, remote education, remote medical treatment and online live broadcast systems. Streaming media technology has gained rapid development in recent years as a sign of new generation internet applications.

The streaming media server: the method is a core system of streaming media application and a key platform for providing video service for users by operators. The main functions of the streaming media server are to collect, cache, schedule, transmit and play streaming media contents.

The bullet screen server: refers to a platform that provides the user with associated barrages for each video.

The public protocol: the method refers to a protocol which is commonly used in the technical field of the technical industry, in the application, in the multi-level interaction technical field, a used passing protocol is a public protocol, and specifically, the public protocol can be a protocol specified by Digital Living Network Alliance (DLNA).

Private protocol: the video system is a protocol established according to personalized requirements or special requirements of multi-party communication, and in the application, screen projection source equipment and screen projection target equipment belonging to the same video system can communicate by using a private protocol. For example, in the application, in the mobile phone used by the screen projection source device, the producer of the video played in the mobile phone is a, and the private protocol can be used for communication in the process of projecting the video into the television through the video set-top box of the a.

In a specific practice process, the inventor of the present application finds that, when a screen projection source device in the prior art projects a target video on a screen projection target device for display, the screen projection target device cannot acquire the bullet screen server of the associated bullet screen information of the target video, and thus cannot acquire the bullet screen information associated with the target video.

Based on the above problem, the inventor of the present application first invented a video playing control method based on a private protocol, in which a target video is projected and displayed through a projected target video of the same video system corresponding to the target video, specifically, the same video system refers to the same video producer or the same video generation platform.

For example, a video is run in a mobile terminal such as a mobile phone, a video source of the video is an a video production platform, and meanwhile, a user is also configured with a digital video transform box corresponding to the a video production platform or a smart television corresponding to the a video production platform. The video projection display in the mobile terminal can be displayed in a common television connected with a digital video conversion box corresponding to the A video production platform, or the video projection display in the mobile terminal can be displayed in a smart television corresponding to the A video production platform.

The specific implementation manner is as shown in fig. 1, a user uses a mobile terminal to watch a video, and initiates a screen casting request to the smart television aiming at the video a, and after receiving the screen casting request, the smart television acquires the video a from the video production platform a according to the unique identification information of the video a in the screen casting request on the video production platform a, and plays the video a in the smart television.

When a user watches the barrage information related to the video a by using the mobile terminal, the user sends a barrage playing request to the intelligent television through the mobile terminal, and after receiving the barrage playing request, the intelligent television acquires the barrage information from the video A production platform according to the identification information of the video a corresponding to the barrage playing request and displays the barrage information in the intelligent television.

Through the process, the effect of projecting the barrage information into the screen projection target equipment under the same video system is achieved.

Further, the inventor of the present application has conceived a video playback control method. In this embodiment of the application, when a user needs to screen a target video on a screen projection target device, the screen projection target device may obtain the target video from a streaming media server according to a uniform resource locator URL in a screen projection request and play the target video, that is, obtain target video information from the streaming media server according to the URL corresponding to the target video, instead of sending identification information of the target video to a video production platform corresponding to the target video to obtain the target video.

Furthermore, the screen projection target device receives a screen projection play request of the screen projection source device for the target video, and determines second identification information of the screen projection server corresponding to the identification information of the streaming media server according to the first identification information of the streaming media server carried in the URL, that is, since the URL has related information of the streaming media server and the screen projection server corresponding to the screen projection information related to the target video has an association relationship, the second identification information of the screen projection server corresponding to the identification information of the streaming media server can be determined through the first identification information of the streaming media server carried in the URL.

After the second identification information of the barrage server is obtained, the screen projection target device obtains barrage information associated with the target video from the barrage server according to the second identification information, and displays the barrage information when the target video is played.

According to the video playing control method, when the target video is obtained, the URL of the storage position of the target video world wide web is used, compared with the method for obtaining the target video by using the video identification information of a certain video production platform in the prior art, the method can obtain the target video based on the URL, can analyze the identification information of the bullet screen server associated with the target video, and can obtain the target video and the associated bullet screen information.

To further illustrate the technical solutions provided by the embodiments of the present application, the following detailed description is made with reference to the accompanying drawings and the detailed description. Although the embodiments of the present application provide the method operation steps as shown in the following embodiments or figures, more or less operation steps may be included in the method based on the conventional or non-inventive labor. In steps where no necessary causal relationship exists logically, the order of execution of the steps is not limited to that provided by the embodiments of the present application.

The following describes the technical solution provided in the embodiment of the present application with reference to the application scenario shown in fig. 2.

Referring to fig. 3, an embodiment of the present application provides a video playback control method, including:

step S301, when the screen projection target device receives a video screen projection request sent by the screen projection source device, the screen projection target device acquires a target video from a streaming media server according to a Uniform Resource Locator (URL) in the video screen projection request, and plays the target video.

In the application, before the screen projection target device receives a video screen projection request sent by the screen projection source device, the screen projection source device already obtains a target video from a streaming media server, plays the target video in the screen projection source device, and sends the screen projection request to the screen projection target device when the screen projection source device needs to perform video screen projection.

In the application, the screen-casting request may be triggered in various ways, and in an optional embodiment, the screen-casting source device receives the screen-casting request triggered by the user clicking a screen-casting control in the video application interface, or the screen-casting device receives the screen-casting request triggered by the user through voice, or the screen-casting request is triggered by setting a combination key. Exemplarily, as shown in fig. 4, the screen projection source device is a mobile terminal, a target video is played in the mobile terminal, a screen projection control is provided in a playing interface of the mobile terminal, and a screen projection request is triggered by clicking the screen projection control by a user; in another alternative embodiment, as shown in fig. 5, the user triggers a screen-casting request to the mobile terminal through voice.

In the embodiment of the present application, a premise that the screen projection target device and the screen projection source device communicate with each other is that the screen projection target device and the screen projection source device are located in the same network environment, and the screen projection target device and the screen projection source device are connected through a pairing connection process. The connection between the screen projection target device and the screen projection source device needs to be established through a communication protocol or a communication method, optionally, the connection between the screen projection target device and the screen projection source device can be realized through a DLNA technology, and the DLNA regulates the whole application into 5 functional components. From bottom to top in sequence: network interconnection, network protocols, media transport, discovery control and management of devices, media formats.

The network interconnection specifies the type of the accessed network, namely the network used by the screen projection target device and the screen projection source device. The network protocol specifies the network protocol used by the screen projection target device and the screen projection source device. Media transport specifies that all DLNA devices (including the screen projection target device and the screen projection source device) must support media transport using the hypertext transfer protocol HTTP protocol. The discovery of devices refers to a method for discovering devices that can be controlled and managed by DLNA technology, such as a screen projection target device and a screen projection source device. The media format specifies the media format when the screen projection target device shares and uses digital media and content with the screen projection source device.

Illustratively, when the screen projection target device and the screen projection source device are located in the same wireless network, the screen projection control is triggered through a video software client in the screen projection source device, because the screen projection source device does not establish communication connection with the screen projection target device, an interface for searching the screen projection target device in the same network environment is displayed in the screen projection source device, if the screen projection target device is found, the screen projection target device is displayed, and connection between the screen projection target device and the screen projection source device is completed through selecting connection establishment with the screen projection target device.

According to the content, after the screen projection target device and the screen projection source device are communicated through the DLNA technology, the screen projection effect can be achieved, so that in the embodiment of the application, the connection between the screen projection target device and the screen projection source device can be established through a public protocol, the convenience of the connection between the screen projection target device and the screen projection source device is realized, a private protocol is not required to be established in order to realize the connection between the screen projection target device and the screen projection source device, and the universality of the embodiment of the application is also improved.

Of course, the connection process between the screen projection target device and the screen projection source device may also be other communication processes, which are not limited in this application.

In the embodiment of the application, when the screen projection source device sends a video screen projection request to the screen projection target device, the video screen projection request includes the same resource locator URL, and the URL corresponds to a specific resource of the server, such as a hypertext markup language HTML page, a picture, a video segment, and the like. The URL represents the position information of the network resource of the target video corresponding to the video screen projection request, and the position information has uniqueness, so that after the screen projection target equipment acquires the URL, the screen projection target equipment can be connected to the storage position of the target video in the streaming media server according to the URL, acquire the target video from the streaming media server and play the target video.

The specific URL structure at least comprises a mode (or a protocol), a server name (or an internet protocol IP address), a path and a file name, the URL can indicate how a screen projection target device processes a corresponding target video, the target video is determined from the path and the file name corresponding to the URL in the streaming media service, and the target video is acquired.

In an optional embodiment, the target video is a streaming video, and the streaming server compresses the target video and then sends the data of the target video in segments, that is, the data of the target video played by the screen projection target device is downloaded data, but the data that is not downloaded cannot be directly viewed.

In the embodiment of the application, after the screen projection source device finishes the interaction with the screen projection target device, the screen projection source device can not play the target video any longer, and the content of the target video is only displayed in the screen projection target device.

Step S302, the screen projection target device receives a screen projection play request of the screen projection source device for the target video, and determines second identification information of the screen projection server corresponding to the first identification information of the streaming media server according to the first identification information of the streaming media server carried in the URL.

Specifically, in the embodiment of the application, when it is determined that the barrage information needs to be displayed on the screen projection target device, the screen projection source device triggers a barrage playing request, and after receiving the barrage playing request, the screen projection target device acquires the corresponding barrage information.

In an optional embodiment, the screen projection source device receives a screen projection request triggered after a user clicks a screen projection control in a video application interface, or the screen projection source device receives a screen projection request triggered after the user clicks a screen projection control in the video application interface, or the screen projection source device triggers the screen projection request by receiving a voice operation instruction of the user, or the screen projection source triggers the screen projection request by receiving a set combination key triggered by the user. As shown in fig. 6, for example, a target video is played in the screen projection source device, and the target video is already projected to the screen projection target device for playing, a video software playing client of the screen projection source device has a screen projection control, and after a user clicks the screen projection control and determines that the state of the screen projection control is a selected state, the screen projection source device triggers the screen projection playing request.

In this embodiment, as shown in fig. 7, there is also a method for optionally triggering a barrage play request, where a user may send barrage state change information to a screen projection source device by controlling a barrage control in a screen projection target device when the user clicks the barrage control, and after receiving the barrage state change information, the screen projection source device determines to trigger the barrage play request and sends the triggered barrage play request to the screen projection target device.

After receiving a bullet screen playing request of a screen projection source device for a target video, a screen projection target device determines a bullet screen server through information carried by a Uniform Resource Locator (URL) used when the target video is obtained. Specifically, the URL carries identification information of the streaming media server, and since the server for storing video data of the same video and the server for storing associated bullet screen information have an association relationship, the identification information of the bullet screen server can be determined by the identification information of the streaming media server.

For example, for a target video a, the target video a is a video of an a video production platform, so the streaming server corresponding to the target video a is the streaming server in the a video production platform, and the barrage information generated by commenting on the target video a by the user is stored in the barrage server in the a video production platform, so if the identification information of the streaming server corresponding to the target video a is determined, the a video production platform is determined, and then the identification information of the barrage server in the a video production platform can be determined.

Therefore, in the embodiment of the present application, the screen projection target device determines, according to the first identification information of the streaming media server carried in the URL, the second identification information of the barrage server corresponding to the identification information of the streaming media server.
