Abstract

A data transmission method, device, electronic device, and storage medium provided in the embodiments of the present application are applied to the transmission of IP data streams, and the method includes: buffering the first IP data stream that is currently output among multiple IP data streams IP data packet; determine whether the load of the IP data packet corresponding to each frame baseband signal has suspected abnormal content; if there is suspected abnormal content in the load of the IP data packet of any one of the baseband signals, then corresponding to the first IP data stream The abnormal timer starts counting; when the abnormal timer count value reaches the preset threshold, switch the second IP data flow different from the first IP data flow among the plurality of IP data flows. By detecting whether the load content of the IP data packet is abnormal, if it is abnormal, it will start timing. When the timing reaches the preset threshold, it can switch to the normal IP data flow in time, so that the quality of the transmitted IP data flow can meet the needs of special environments. .

Description

technical field [0001] The present application relates to the technical field of communications, and in particular, to a data transmission method, device, electronic equipment, and storage medium. Background technique [0002] In modern society, there are many occasions that require high transmission of uncompressed video signals, such as television broadcasting, conference television, concerts and press conferences. In the process of uncompressed video signal network transmission, signal loss or abnormality often occurs, so multiple links will be set up to transmit multimedia signals to ensure that the normal link can be switched when the signal transmission process is abnormal. Ensure high-quality transmission of signals. [0003] However, the detection and switching of traditional signal links often convert IP signals into baseband signals, and then convert them into IP signals after detection and switching. High quality requirements for transmission. Contents of the ...
