Abstract

The invention is suitable for the technical field of communication, and provides a data transmission method and a sending and receiving device, and the method comprises the steps that a sending end obtains round-trip time, employs a data transmission mechanism of a preset type to process to-be-sent data according to the round-trip time, and sends the processed data to a receiving end; when detecting that the received data packet is lost, the receiving end recovers the lost data packet according to a data transmission mechanism of a preset type. The data transmission method provided by the invention can adapt to a complex network environment and ensure the quality of data transmission.

Description

technical field [0001] The present application belongs to the technical field of communication, and in particular relates to a data transmission method and a sending and receiving device. Background technique [0002] With the rapid development of the mobile Internet, it is becoming more and more common to use terminals such as mobile phones to watch live broadcasts, conduct video communications, and video conferences. However, in a wireless transmission environment, factors such as signal stability, packet loss rate during transmission, and network bandwidth affect the transmission performance of multimedia streams. In order to improve user experience, it is necessary to improve the quality of audio and video transmission and reduce delay during data transmission. The current data transmission method is generally simple forward error correction or packet loss retransmission, the data transmission method is relatively simple, and cannot adapt to the complex network environm...
