A system and method for intelligently adjusting the real-time live broadcast bit rate of an IP camera

Abstract

The embodiment of the present invention discloses a system and method for intelligently adjusting the real-time live streaming code rate of an IP camera. Network speed; set the clipping limit points synchronized with the uplink network speed time node at the upper and lower positions of the original video data; add a data clipping blank layer to the clipping limit point of the original video data; clip the data clipping blank layer The original video data after cutting and the original audio data are asynchronously classified and encoded, and the maximum data size that can be transmitted by the compressed and encoded audio data stream and the target video data stream is monitored in real time, and the cutting depth of the data cutting blank layer is adjusted; the audio data stream and the The target video data stream is pushed to the live server synchronously. This solution monitors the speed of the uplink network in real time, automatically adjusts the data upload bit rate, keeps the link of the live broadcast terminal constant, and improves the viewing experience.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of IP camera live broadcasting, in particular to a system and method for intelligently adjusting the code rate of IP camera real-time live broadcasting. Background technique [0002] IP camera (network camera) is a new generation of product combining traditional camera and network video technology. In addition to having all the image capture functions of general traditional cameras, it also has a built-in digital compression controller and a WEB-based operating system to make video After the data is compressed and encrypted, it is sent to the end user through the LAN, Internet or wireless network. The remote user can use a standard web browser on the PC to access the network camera according to the IP address of the network camera, monitor the situation of the target site in real time, edit and store the image data in real time, and control the camera at the same time The PTZ and l...

Problems solved by technology

However, this does not cover all the needs. For example, many cameras have IP functions, but do not have streaming functions. That is, they have network functions, but they cannot broadcast the content collected by the cameras. Therefore, during mobile live broadcast, IP cameras are generally compatible with mobile phones. Wait for other mobile terminals to connect, the collected audio and video data is compressed and encoded by the software of the mobile terminal, and the stream is pushed and distributed to the live broadcast terminal for viewing

[0004] However, since the streaming of audio and video data only depends on the uplink network of the mobile terminal, if the network condition deteriorates, if the bit rate of the audio and video data is not adjusted, the audio and video will freeze, which will seriously affect the viewing experience.
