Abstract

The invention discloses a data transmission method and device and an electronic device. The data transmission method and device and the electronic device relate to data transmission and storage technology and can reduce network resource cost and framing time delay. The data transmission method comprises steps of cutting a data frame to be transmitted into one or more than one load data packets with predetermined lengths, adding a real-time transmission protocol header to each load data packet, marking a filling bit mark in the real-time transmission protocol header as being filled, in a filling filed corresponding to a filling bit, performing marking on a data kind bit, a frame beginning bit, a frame finishing bit and a load data packet kind bit of the load data packet to obtain a packagedreal-time transmission protocol data packet, and transmitting the packaged real-time transmission protocol data packet. The data transmission method and device and the electronic device are applicable to performing RTP packaging on the data and then transmitting.

Description

technical field [0001] The invention relates to data transmission and storage technologies, in particular to a data transmission method, device and electronic equipment. Background technique [0002] With the continuous development of computer communication and Internet technology, especially 4G communication technology, electronic equipment, such as smart mobile phones, personal digital assistants, handheld computers, notebook computers, etc., are more and more widely used, and the application programs installed in electronic equipment ( APP, Application) are more and more, and the application functions provided are becoming more and more abundant. For example, with the development of streaming media technology, users can realize synchronous playback of multiple channels of audio and video data through a player installed in an electronic device, thereby greatly enhancing and enriching user experience. [0003] At present, when realizing synchronous transmission of multiple...
