Problems solved by technology
But at the same time, it also brought a big problem: the amount of data has greatly increased
In the era of standard definition, the bit rate of a single D1 resolution is about 1.5~2Mbps, but the bit rate of high-definition 2 million pixels has increased to 8Mbps, which has increased by more than three times at once. In the transmission of audio and video data, often Due to transmission delay and instability, the intelligent monitoring platform cannot preview the monitoring situation in real time

The invention discloses a method and a device of equalized audio-video data transmission based on an intelligent monitoring platform. The method comprises the following steps: receiving the audio-video data transmitted by a network camera module, selecting threads according to each status value recorded by each thread of a plurality of threads, transmitting the audio-video data to a receiving processing module through a transmission path which is bound with a selected thread and updating the status value of the selected thread, and receiving and processing the audio-video data. The network camera module comprises a plurality of cameras used for camera shooting and monitoring. According to the method and the device of equalized audio-video data transmission based on the intelligent monitoring platform, the speed of audio-video data concurrent receiving and processing is increased, unnecessary delay in transmission process is avoided, and response speed is fast and stability is high. With the high performance, the method and the device of equalized audio-video data transmission based on the intelligent monitoring platform can be widely applied to the field of monitoring.
Description
technical field [0001] The invention relates to a method and device for transmitting audio and video data, in particular to a method and device for balanced transmission of audio and video data based on an intelligent monitoring platform. Background technique [0002] At present, as network high-definition camera technology becomes more and more mature, the application scope of the corresponding intelligent high-definition monitoring platform is also wider and wider, and it has penetrated more or less in almost all industries. Therefore, intelligent monitoring Users of the platform also penetrate into various industries. Typical users include intelligent monitoring construction users of power substations, public security users in safe city construction, traffic police users in the field of intelligent transportation, bank users in financial monitoring, and education system users, etc. [0003] The application scheme of the intelligent monitoring platform is relatively matur...
