A real-time multi-view audio and video transmission method

Abstract

A real-time multi-view audio and video transmission method, which includes: S1: power-on connection: after the device layer is powered on, it is in a standby state, and at the same time sends UDP data packets at fixed intervals; the APP data processing layer of the user terminal is based on the UDP data sent by the device layer Packet establishment management mechanism, automatically search the number of devices connected to the wireless network according to the received UDP data packets after starting up, select the device that needs to connect to the wireless network, and send the TCP protocol to the target device to establish a connection; S2: Disconnect and reconnect: device Layer fixedly sends UDP data packets, and the user terminal keeps monitoring the device connection information in the UDP data packets; when the APP data processing layer finds that the device layer is disconnected, it will automatically stop related operations internally, terminate the ongoing process, and display as " Not connected", the APP layer will not run the program normally until the device layer reconnects to the network. The invention can be applied to communication between short-distance wireless devices and has reliable communication quality.

Description

technical field [0001] The invention mainly relates to the field of network communication data transmission, in particular to a real-time multi-view audio and video transmission method. Background technique [0002] Network multimedia communication is a brand-new communication technology that combines network and traditional communication, and plays an increasingly important role in the network era of digital information convergence. Among them, with the maturation of technologies such as wireless transmission and audio and video encoding and decoding, wireless multimedia communication has become a hot spot in the field of communication today, and is widely used in various occasions. For example, natural geological disasters have occurred frequently in recent years, and traditional communication based on mobile base stations has little effect. This communication problem is well solved by establishing audio and video wireless transmission. [0003] The traditional IP protoco...

Problems solved by technology

[0003] The traditional IP protocol does not include error detection and correction functions for data errors in the process of transmitting data between computers, so the reliability of data exchange cannot be guaranteed. Therefore, some practitioners have designed a connection-oriented transport layer protocol. , that is, the TCP protocol, and combining this protocol with the IP protocol forms the well-known TCP / IP protocol
