Reconfigurable software unit upgrading method

Abstract

The invention relates to the embedded software field, in particular to a configurable software unitization upgrading method aiming at digital television set-top boxes. The invention puts forward a configurable, flexible, efficient and safe software on-line upgrading method. The method comprises the following steps that: a. upgradeable software and data having fixed storage addresses are marked into individual unit modules, and module configuration information is established for each unit module and stored on a terminal; b. the upgrading data and configuration information of all the unit modules needing to be upgraded are packaged to generate upgrade files and configuration files; c. a code stream generation tool is used to form code streams of the upgrade files and configuration files and send the code streams out; d. the terminal downloads the configuration files to judge which modules are needed for upgrading the terminal, and then downloads the upgrade files of the modules needing to be upgraded so as to carry out upgrading. The upgrading method is flexible in upgrade, high in efficiency, good in safety and suitable for the upgrade of embedded software.

Description

Configurable software unitized upgrade method Technical field The invention relates to the field of embedded software, in particular to a configurable software unitized upgrade method for digital television set-top boxes. Background technique With the continuous development of digital TV, the number of digital TV users has also risen sharply, and the digital TV business has also developed vigorously, with more and more content and functions. The module composition of embedded set-top box software has also been enriched. On the other hand, due to the function The size of the set-top box software has become larger and larger, and the update appears frequent and complicated. In the digital TV set-top box software upgrade, online upgrade has the lowest cost and the highest efficiency. This is also the only way for end users to upgrade by themselves. In the traditional online upgrade method, the upgrade process needs to download the entire application and resource data, and rewrite t...
