Embodiment Construction

[0072] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0073] In order to enable faster, smoother, and low-latency video transmission in the case of a poor network, the inventor of this case conducted in-depth research and finally proposed a video transmission method with better effects. The basic idea of ​​the video transmission method yes:

[0074] The image frames to be transmitted are divided into multiple areas with different priorities. When the network quality deteriorates, in order to ensure that the image...

Abstract

The invention provides a video transmission method, device and system, equipment and a storage medium, and the method comprises the steps: segmenting a to-be-transmitted target image frame in a targetvideo into a plurality of regions with different priorities; obtaining a currently predicted bandwidth as a target bandwidth; when the target bandwidth is smaller than the maximum bandwidth, allocating a corresponding target code rate to each region according to the target bandwidth, the priority of each region and the maximum code rate corresponding to each region; and performing compressed encoding on the corresponding regions according to the target code rates corresponding to the regions, and sending compressed encoding results of the regions to receiving end equipment. According to the video transmission method provided by the invention, when the network becomes poor, it can be ensured that the important region in the target image frame has good video quality, and it can also be ensured that the target image frame can be transmitted to the receiving end device quickly and smoothly with low delay.

Description

technical field [0001] The present application relates to the technical field of video transmission, and in particular to a video transmission method, device, system, equipment and storage medium. Background technique [0002] In some application scenarios, it is necessary to transmit the target video to a designated device through a wireless network. For example, wireless projection is used in conference scenes, teaching scenes, etc. Wireless projection is to transmit the target video to the receiving end through a wireless network The receiving end device of the device is displayed. [0003] However, the wireless network has characteristics such as instability and mutual interference, so it will not always maintain a high transmission rate. How to perform video transmission faster, smoother and with low delay in the case of a poor network is currently an urgent issue. problem to be solved. Contents of the invention [0004] In view of this, the present application prov...
