Abstract

The embodiment of the invention provides an analog composite video signal sending method and device and an analog composite video signal display method and device, and the sending method comprises thesteps: respectively converting received digital video image data into digital video image data in a first format and digital video image data in a second format; analyzing the digital video image data in the first format to obtain intelligent information data, the intelligent information data being used for recording parameter information in the digital video image; performing encoding and digital-to-analog conversion on the intelligent information data and the digital video image data in the second format to obtain an analog composite video signal with the intelligent information data; sending the analog composite video signal, extracting and encoding the intelligent information data recording the parameter information together with the digital video image data to be transmitted, and theproblems of poor synchronization effect and high cost caused by video and intelligent information transmission of a data transmission system based on a digital video in the prior art are solved.

Description

technical field [0001] The present invention relates to the field of audio, video and communication technologies, in particular to a method and device for transmitting analog composite video signals, and a display method and device. Background technique [0002] In recent years, with the generalization of the application of artificial intelligence represented by deep learning in the field of security, more and more intelligent monitoring systems have been developed. The intelligent monitoring system needs to transmit video information and auxiliary data information (such as video frame ID or video time stamp, video intelligent structured information, etc.) between the video acquisition unit, intelligent analysis unit, and application service unit. , that is, zero tolerance for bit errors. [0003] Although the existing intelligent monitoring systems have different applications and various algorithms, they are basically based on digital video and data transmission systems fo...
