Method and system for data transmission

Abstract

The invention discloses a method for data transmission. The method is used for an object carousel system consisting of a front end and a terminal and comprises the following steps of: requesting to acquire a directory tree structure of a webpage from the front end by using the terminal and establishing the directory tree structure of the webpage according to the data acquired by the request; determining the hierarchy which the page requested to be opened by a browser at present belongs to; requesting to acquire file data corresponding to the page requested to be opened at present from the front end; displaying the page and caching the data according to the data acquired by the request; requesting to acquire file data corresponding to a next-stage page of the page requested to be opened atpresent; caching the file data which the next-stage page corresponds to and is acquired by the request; and then waiting for the next request of the browser. The invention also discloses a system fordata transmission. The method and the system for data transmission has the advantages of reducing occupied storage space when the front end stores the webpage data, preventing the terminal from receiving repeating data repeatedly when requesting data, and improving the effective downloading speed of the terminal.

Description

technical field [0001] The present invention relates to computer technology, in particular to a method and system for data transmission. Background technique [0002] Object Carousel (OC) is based on the DSM-CC (DigitalStorage Media-Command&Control) protocol in the digital TV system. data broadcasting service for sex broadcasting. OC is mainly used to download static data files and supports DVB-J (Digital Video Broadcasting-Java) and DVB-H (Digital Video Broadcasting-HTML) applications. Basic applications include: Sunshine Government Affairs, Weather Forecast, Travel, Stocks, Games, etc. [0003] A typical OC application system includes two parts: the OC front-end (that is, the information publishing end, hereinafter referred to as the front end) and the OC terminal (that is, the information receiving end or the information requesting end, hereinafter referred to as the terminal). When the OC application system broadcasts web pages data, the existing front-end mostly adop...

But this method also has some limitations:

It can be seen that this method of building a directory tree through blind inspection is not accurate and time-consuming

[0010] On the other hand, in addition to the higher-level homepage and second-level web pages, the content of the third-, fourth-level and lower-level pages usually have certain relevance or similarity, and generally include some similar or similar content when designing web pages. Similar background pictures and other files, so in the prior art, all the files of each page are stored separately in the directory corresponding to the page, which will make the directory corresponding to these related or similar pages contain There are some duplicate files, which not only uselessly occupy the storage space of the front end, but also cause the terminal to repeatedly receive duplicate data when requesting data, thus substantially reducing the effective download speed of the terminal
