AI Technical Summary

Technical Problem

Existing video transmission methods have poor adaptability to external interference, are prone to packet loss, packet errors and large video delays, and involve a large number of devices and complex data processing.

Method used

A video transmission method that adapts to both broadband and narrowband channels is adopted. The transmission strategy is adjusted in a timely manner through video acquisition, encoding, channel information acquisition and processing modules. Data packets are transmitted in a hierarchical manner using broadband and narrowband channels, and the transmission level is adjusted in real time according to the channel quality.

Benefits of technology

It improves the anti-interference capability of video transmission, reduces packet loss and latency, simplifies the number of system devices, and improves channel utilization.

Abstract

The application discloses a video transmission method suitable for wideband and narrowband channels, comprising the following steps: a video acquisition module acquires image transmission to a video encoding module; the video encoding module encapsulates video data; a to-be-transmitted data sending management module transmits the video data to a video receiving module through wideband and narrowband transmission channels; the to-be-transmitted data sending management module transmits the video data in the wideband and narrowband channels respectively; the to-be-transmitted data sending management module acquires signal strength rssi and sends the calculated distance d change rate k to a channel information acquisition and processing module; the video receiving module calculates the video data packet loss rate l and the data packet receiving time delay t and sends them to the channel information acquisition and processing module; the channel information acquisition and processing module calculates the channel transmission effect judgment value y; the data transmission level is adjusted according to the channel transmission effect judgment value y; the video receiving module receives the data and transmits the data to a video decoding module for decoding and then displays the data by a video display module.
