Data transmission method and device based on a remote exhibition and marketing system

Abstract

The invention relates to a data transmission method and device based on a remote exhibition and marketing system. The method comprises the following steps: A, collecting images of a display stand at atime interval that can be dynamically changed; B, comparing a front-frame image collected at the current time interval with a back-frame image collected at the previous time interval, and comparing the front-frame image collected at the current time interval with a back-frame image collected at the current time interval to detect whether image changes occur; C, adding video data composed of the image of each frame collected at the current time interval into a transmission queue once image changes are detected, otherwise, adding the front-frame image collected at the current time interval intothe transmission queue; D, carrying out transmission after conducting compression or interpolation on the data in the transmission queue. The device includes corresponding modules for implementing the above method. The technical scheme of the invention improves a software system of a remote exhibition and marketing system, makes data transmission more efficient, saves the data transmission bandwidth, and does not affect the real-time property of on-site interactive transmission.

Description

technical field

[0001] The invention relates to a network data transmission method, in particular to a data transmission method and device based on a remote exhibition and sales system. Background technique

[0002] In today's environment of rapid development of e-commerce, people can not only understand the product situation through text descriptions, pre-shot videos and pictures when shopping remotely, but also merchants and sellers complete sales and transactions through real-time video of products. system. Such a remote exhibition and sales system can intuitively understand the appearance, style and size of commodities in real time during the purchase process. For example, the patent document titled "A System for Remote Trading of Fresh Agricultural Products" filed by the inventor with the publication number CN104951972A discloses this remote display system for real-time video transmission.

[0003] However, long-term video and audio transmission in the system not only...
