Device, system and method for reducing repeated downloading of images through identification codes

Abstract

Disclosed is a device, a system and a method for reducing repeated downloading of images through identification codes, wherein, a sending end is used to firstly transmit a transmission identification code of the corresponding image to a receiving end, a program for downloading the image is terminated when the receiving end judges that the received transmission identification code is recorded in a configuration file, and the image is saved from the sending end when the receiving end judges that the received transmission identification code is not recorded in the configuration file, thereby achieving the technical effect of reducing bandwidth waste.

Description

technical field [0001] A picture transmission device, system and method thereof, in particular to a device, system and method for reducing repeated downloading of pictures by transmitting identification codes. Background technique [0002] With the development of information technology and the Internet, the way of delivering messages has gradually changed from traditional letters to e-mails and text messages, and recently to more real-time instant messaging services to deliver messages to contacts. Currently, there is a tendency to use instant messaging to communicate with contacts more than using telephones. [0003] The real-time communication service is a service in which the terminal is connected to the real-time communication network. The biggest difference between instant messaging and non-real-time communication methods such as e-mail is that the conversation of instant messaging is real-time. When the user / contact person sends message data to the contact person / use...

Problems solved by technology

However, when the current real-time message displays the picture that the user wants to send to the recipient, it does not matter whether the recipient has already received the picture that the user wants to send from other contacts, or even the user sends the same picture to the recipient for the second time. Receiver, it is easy for the receiver to download the received pictures again, resulting in a waste of bandwidth

[0005] To sum up, it can be seen that there has been a problem in the prior art for a long time when pictures are received by real-time communication services, and the pictures are often downloaded repeatedly. Therefore, it is necessary to propose improved technical means to solve this problem
