Abstract

The invention provides a data transmission method and system, relates to the technical field of electronic information, and can solve the problem of low data processing efficiency caused by increaseddata volume during image frame sequence encoding due to low comparison similarity between a reference image frame and an image frame sequence during data transmission based on a reference image frameencoding method. The specific technical scheme is as follows: after acquiring an image frame sequence, transmitting equipment acquires a target reference image frame corresponding to the image frame sequence according to a preset algorithm, performs encoding processing on the image frame sequence through the target reference image frame, and transmits the encoded image frame sequence and the encoded target reference image frame to receiving equipment. And after the receiving equipment acquires the coded image frame sequence and the target reference image frame corresponding to the coded targetframe sequence, the coded image frame sequence is decoded according to the target reference image frame to obtain the image frame sequence. The present disclosure is used for data transmission.

Description

technical field [0001] The present disclosure relates to the field of electronic information technology, in particular to a data transmission method and system. Background technique [0002] With the development of information technology, people's requirements for communication services are constantly increasing, and the contradiction between image communication and communication network capacity is becoming increasingly prominent. Especially for video image communication, due to its huge amount of data, it will be difficult to transmit and store data without image compression. Therefore, image compression capability is particularly important for video images. [0003] Image compression is the application of data compression technology to digital images, with the purpose of reducing redundant information in image data, so as to store and transmit data in a more efficient format. [0004] In order to improve the efficiency of data transmission and storage, the existing tech...
