Abstract

The embodiment of the invention provides a multimedia data transmission method and a camera. The transmission method comprises the following steps: detecting whether the round-trip delay of a data packet in a network connection based on a transmission control protocol TCP is greater than a first delay threshold; If yes, reducing the multimedia data generated by the camera equipment in unit time; And sending the reduced multimedia data through the network connection. By applying the scheme provided by the embodiment of the invention, the network congestion condition can be improved, the stability during multimedia data transmission is improved, and the jamming phenomenon during audio and video playing at a receiving end is reduced.

Description

technical field [0001] The present application relates to the technical field of data transmission, in particular to a multimedia data transmission method and a camera. Background technique [0002] Multimedia data includes data such as audio and video. In the field of video surveillance, the camera can send the collected multimedia data to the receiving end through a network connection based on Transmission Control Protocol (TCP). When the receiving end receives the multimedia data sent by the camera, it can play the multimedia data in real time. data so that users can watch and listen to the video and audio recorded by the camera. [0003] However, data sent over a network connection is prone to congestion when network conditions are poor. At this time, the multimedia data collected by the camera cannot be stably sent to the receiving end through the network connection, causing the audio and video playback of the receiving end to freeze or disconnect, and the user experi...
