However, in the process of multimedia teaching, due to the limited resources of teachers, the live content is often repeated. If each teaching point is equipped with a teacher to teach the same live content, it will lead to waste of teaching resources and high teaching costs. Therefore, There is an urgent need for a teaching program to reduce the cost of teaching

The embodiment of the invention provides an online live broadcast system. The online live broadcast system comprises a live broadcast content acquisition device, a live broadcast content management device, a live broadcast content transmission device, and a live broadcast content playing device; the live broadcast content acquisition device is used for carrying out real-time image acquisition andcompression on live broadcast contents to generate compressed images with different alternative playing code rates; the live broadcast content management device is used for storing the compressed images with different alternative playing code rates generated by compression, parsing an access request to obtain an address of the live broadcast content playing device and an actual playing code rate,so as to obtain a compressed image with the alternative playing code rate consistent with the actual playing code rate for decoding to generate a decoded image, and distributing the decoded image to the live broadcast content transmission device according to the address of the live broadcast content playing device; the live broadcast content transmission device is used for distributing the decodedimage to the live broadcast content playing device; and the live broadcast content playing device is used for sending the access request and receiving the decoded image distributed by the live broadcast content transmission device and playing the decoded image.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of online live broadcasting, and in particular to an online live broadcasting system. Background technique [0002] Multimedia teaching means that in the teaching process, according to the teaching objectives and the characteristics of the teaching objects, through teaching design, rationally select and use modern teaching media, and organically combine with traditional teaching methods, participate in the whole teaching process together, use various media information For students, a reasonable teaching process structure is formed to achieve the optimal teaching effect. [0003] With the development of multimedia teaching technology, in the teaching process, in addition to using a conventional whiteboard for writing, a projector is also added, and the live content is projected onto a soft hanging curtain through the projector. In the traditional teaching process everything is decid...
