Method for downloading user interface corresponding to smart card for set top box through Cable lines

Abstract

The invention relates to a method for downloading a user interface corresponding to a smart card for a set top box through Cable lines. The method comprises that the set top box determines a user group which a user belongs to according to the characteristic value of the smart card; the set top box downloads the image data and the interface information of the user interface corresponding the user group through the Cable lines. The method for downloading the user interface corresponding to the smart card for the set top box through the Cable lines enables various user groups, such as villages and towns, to enter various interfaces on low-rank one-way stet top boxes without the aid of network browsers and to download the corresponding interface information and the corresponding image data through the Cable lines according to the characteristic value of the smart card; can ensure that various user groups such as villages and towns can enter the corresponding interfaces and various data broadcasting pages to check conditions such as village general situations, convenience information, three-service publication and public service; is easy to apply and wider in application range.

Description

technical field [0001] The invention relates to the field of digital video broadcasting, in particular to the field of user interface of digital video broadcasting, and specifically refers to a method for realizing a set-top box downloading a user interface corresponding to a smart card through a Cable line. Background technique [0002] The interface of the set-top box is usually fixed and cannot be changed, especially the low-end and one-way type; the high-end set-top box can be displayed in the form of a web page through a browser, but a browser and network are required, and the main frequency of the CPU is relatively high, otherwise the display will be very slow. [0003] Therefore, if different user groups need to display different interfaces, the interface can be downloaded and updated, and at the same time, the speed must be fast without using a web browser, especially if it can be used on low-end, one-way boxes, then a new interface must be adopted. method.
