Abstract

The invention relates to a police hand-held voice intercommunication method and a system based on the Internet. The voice intercommunication system comprises a server and multiple clients. The voice intercommunication method comprises steps that: the server and the clients connection establishing step, after the server starts and the clients are logged in, connection between the server and the clients are established; the client sending step, one of the clients acquires audio data and transmits the data after coding in a data flow mode to the server end; the server broadcasting step, after the server receives the audio flow, the audio flow is broadcasted to the other clients in the system except the client sending the audio flow; the client playing step, after the other clients receive the audio flow, the audio flow after decoding is transmitted to a loudspeaker for playing.

Description

technical field [0001] The invention relates to a police hand-held voice intercom method, in particular to an internet-based police hand-held voice intercom method. Background technique [0002] In the traditional sense, the police handheld walkie-talkies all use special hardware equipment, which requires relatively high encoding and decoding capabilities of the hardware, and there are short communication distances, relatively single functions of the walkie-talkie, and relatively expensive prices. There are certain disadvantages such as health hazards. In particular, it has high requirements on the external environment and is easily interfered by other external signals. [0003] However, the existing network-based handheld mobile device walkie-talkies have shortcomings such as poor real-time performance, large network bandwidth requirements, poor audio stream quality, low audio stream data encoding and decoding performance, and high power consumption, which will affect the ...
