Embodiment Construction

[0029] see figure 1 As shown, a method for realizing smooth playback of a network theater based on a cloud classroom scene of the present invention, the method includes at least one teacher terminal and a plurality of student terminals; the teacher terminal adopts the standard RTP protocol, and utilizes Multicast function, multicast audio and video streams to the students, thereby reducing network traffic; the teacher's end is customized based on the VLC open source player, including customizing the player interface, optimizing codec parameters, and the encoding of the teacher's end uses the standard H264 stream; it will be played The video stream is decoded by hardware on the student side; at the same time, audio and video synchronization is added to control the playback during the playback process.

[0030] Wherein, the method is further specifically:

[0031] Described teacher's end is provided with data source 1, audio-video decoding module 2, audio-video stream replicati...

Abstract

The invention provides a method for realizing network cinema fluent playing based on a cloud classroom scene. The system according to the method comprises at least one teacher side and multiple student sides. The teacher side uses a standard RTP protocol and broadcasts audio and video streams to the student sides in a multicast manner by using the multicast function of the router in a local area network so as to reduce network traffic. The teacher side is customized based on a VLC open source player and comprises a customized player interface and optimized coding and decoding parameters, and the standard H264 stream is used for coding of the teacher side. The video streams to be played are decoded on the student sides by using hardware, and audios and videos are added in the playing process to perform synchronous control playing. The problem of low fluency in playing 1080P high-definition videos of the network cinema under the cloud classroom can be solved so that fluent playing of the student sides can be realized.

Description

technical field [0001] The invention relates to the technical field of computer software, in particular to a method for realizing smooth playback of a network theater based on a cloud classroom scene. Background technique [0002] During lectures, teachers often need to broadcast videos to students or show a certain student screen to all students, such as: computer class, experimental class. This is a commonly used function in teaching software at present. However, in the cloud classroom scenario, since the student desktops are all virtual desktops, if the audio and video are sent to the virtual desktops of multiple students, it will cause a lot of pressure on the server and occupy a lot of network bandwidth; and because the decoding ability of the virtual desktops is weak, it will causing the following problems: [0003] (1) There is a problem that the playback on the student terminal is not smooth. [0004] (2) The teacher's end and the student's end are not synchronize...
