205. Streaming the target streaming media data to the target terminal based on the target terminal identification so that the target terminal decodes and plays the target streaming media data without a plug-in.

The target streaming media data includes audio and video streaming data, which is not limited herein. It should be noted that, streaming mainly refers to a technical overview of streaming media (such as video, audio or multimedia files) transmitted through a network, and generally includes real-time streaming and sequential streaming. Wherein in embodiments of the present invention, the server adapts real-time streaming to live target streaming media data and applies sequential streaming to on-demand target streaming media data.

Optionally, the server obtains the anti-theft link information and a target streaming media address corresponding to the target streaming media data, and generates a streaming media address to be played according to the target streaming media address and the anti-theft link information, where the streaming media address to be played is used for indicating address information of the target streaming media data of live broadcast or on demand, and the anti-theft link information refers to that an authentication string is added to the target streaming media address, and may be a domain name anti-theft link or other anti-theft links, and is not limited in this specific area. The server adopts the anti-theft chain information to ensure the safe transmission of the target streaming media data and realize the control of the playing authority of the target streaming media data; the server sends the streaming media address to be played to the target terminal based on the target terminal identification, so that the target terminal performs audio and video anti-theft chain authentication on the streaming media address to be played to obtain an authentication result; and the server acquires an authentication result sent by the target terminal, and when the authentication result is that the authentication is passed, the server streams or sequentially streams the target streaming media data to the target terminal in real time, so that the target terminal plays the streamed target streaming media data to a target user in a preset plug-in-free mode. The preset plug-in-free mode specifically means that the server transmits target streaming media data to a preset browser in the target terminal through a full duplex communication protocol websocket, the preset browser decodes the target streaming media data through a scripting language javascript or a virtual instruction set architecture webempty, and then the preset browser performs real-time audio and video playing processing by using canvas and/or a 3D drawing protocol webgl, so that the playing efficiency and the playing fluency of the streaming media data are improved.

The character information input by the target user is used to indicate the character information input by the target user through handwriting, for example, the target user directly inputs the character information through handwriting in a target terminal (for example, a terminal such as a smart tablet computer or a mobile phone) or the target user inputs the character information through handwriting in a smart pen (for example, a dot matrix pen). The smart pen is in signal connection with the target terminal (for example, signal connection is performed through a Bluetooth protocol).

Optionally, the server receives character information input by the target user during the playing process of the target streaming media data, where the character information is used to indicate dot matrix image data including english letters, numbers, punctuation marks, single characters, formulas, words and/or sentences. The server performs stroke order recognition and correction processing on the dot matrix image data through a preset optical character recognition model to obtain interaction request information, and determines interaction response information according to the interaction request information. For example, when the interactive request information is course question information (i.e., a preset application scenario), the server executes a preset packaging function corresponding to the course question information, so as to find a question (i.e., a target question) with the highest similarity to the interactive request information from the database through a preset text similarity recall algorithm, and obtain an answer (i.e., a target answer) corresponding to the question with the highest similarity to the interactive request information, and set the target answer as the interactive response information. The interactive response information includes online learning evaluation information, online test scoring information, online answer information and online course recommendation information, and the interactive response information may also include other interactive information, which is not limited herein. And pushing the interaction response information to the target terminal by the server according to the interaction request information, so that the target terminal displays the interaction response information to the target user. The interactive response information may be text information, image information, animation information or voice information at the target terminal, which is not limited herein.

It should be noted that, the character information input by the target user may also include user voice information, the server may also perform voice recognition on the user voice information to obtain a recognition result, determine corresponding response information according to the recognition result, and display the corresponding response information on the target terminal. For example, the server acquires the online english dialogue voice information of the target user, and the server displays different evaluation levels, for example, excellent excel, good, try again, etc., to the target user according to the online english dialogue information.

Further, the server can record the live micro-class audio/video data on line to obtain recorded micro-class audio/video and playback time period, and store the recorded micro-class audio/video data and playback time period, so that a target user can perform on-demand operation on the recorded micro-class audio/video according to the review time period.
