Embodiment Construction

[0035] The description will now be made in detail of exemplary embodiments, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with some aspects of the invention as recited in the appended claims.

[0036] figure 1 It is a schematic diagram of the implementation environment involved in the present disclosure according to an exemplary embodiment. The implementation environment includes: a sending end 100 and a receiving end 300 .

[0037] The network connection between the sending end 100 and the receiving end 300 is established by wired or wireless means. Therefore, based on the netw...

Abstract

The disclosure discloses a code stream transmission control method and device, including: receiving at least two code streams, the at least two code streams include a first code stream and a second code stream, wherein the first code stream is used as the original main code stream , at least two code streams except the first code stream are used as the original background code stream, and the transmission frame rate of the original main code stream is higher than that of any original background code stream; obtain the main code stream switching signal , the main code stream switching signal indicates to switch the main code stream to the second code stream; continue to receive at least two code streams after switching, wherein the second code stream is used as the new main code stream, and the second code stream is excluded from the at least two code streams Other code streams outside the stream are used as new background code streams. After switching, the transmission frame rate of the new main code stream is higher than the transmission frame rate of any new background code stream. The problem of long response time for playback switching in the prior art can be effectively solved.

Description

technical field [0001] The present disclosure relates to the technical field of data transmission, and in particular, to a code stream transmission control method, device, and computer-readable storage medium. Background technique [0002] With the development of communication technology, more and more scenarios begin to use multiple stream transmission. For example, in the live broadcast of some games, multiple cameras are often set up at the game site to realize the live broadcast of the game site from different angles, and there is usually only one camera at the corresponding live broadcast receiving place (such as the host screen, TV, network video terminal, etc.). Therefore, if you need to watch the live pictures of different cameras, you need to switch the multi-channel code streams transmitted by multiple cameras. [0003] There is an image encoding and decoding process in the transmission of the code stream, and in the image encoding and decoding, the key frame is a...
