Problems solved by technology

At present, due to the need to ensure the safety of manufacturers upgrading digital terminals, the online upgrade solutions of each manufacturer are privately defined methods, without a unified and fixed form, so that digital terminal manufacturers need the license of encryption manufacturers to produce
The data structure and distribution of digital terminal software upgrade methods are also defined privately by each encryption manufacturer, all of which are not conducive to the development of a good operating model for digital terminals in the future

Embodiment Construction

[0028] The method of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] Such as figure 1 As shown, the storage space in the digital terminal can be divided into two parts: the startup software area and the user storage area, and the user storage area can be further divided into multiple storage sub-areas. The user uses the storage area to store the system software of the digital terminal. The system software is divided into multiple software modules according to their functions, usually including a jump module and multiple common software modules. figure 1 In , common software modules are numbered sequentially from 1 to n. Each software module of the system software occupies a storage sub-area of ​​the storage area used by the user, and the software module is identified by the start address of the storage sub-area where the software module is located. The software modules that make ...

Abstract

Method for upgrading system software of digital terminal in DVB system includes steps: partitioning the system software into multiple software modules, and dividing up storage space of digital terminal into multiple storage zones, each software module occupies one piece of storage zone; upgrading system software by using software as unit; when software module in system software is needed to upgrade, the method only transfers upgrading module, which is corresponding to the software module to be upgraded, to the digital terminal; in the digital terminal, the upgrading module replaces the corresponding software module. Allocation of storage space in digital terminal strengthens flexibility for upgrading system software. Advantages are: in time of transferring data, only software module to be upgraded is transferred; in time of upgrading system software; only some necessary software modules are upgraded without need of upgrading all software module.

Description

technical field [0001] The invention relates to a digital terminal system software upgrading method, in particular to a digital terminal system software upgrading method in a DVB system. Background technique [0002] DVB (Digital Video Broadcast) is a digital TV standard formulated in Europe. Digital terminals are client devices connected to the DVB system network, such as set-top boxes. At present, the user's requirements for the digital terminal system software in the DVB system are constantly increasing. With the continuous improvement of the digital terminal system software and the increase of functions, the system upgrade of the digital terminal is also becoming more and more frequent. The upgrade of the digital terminal can be divided into online upgrade and serial port upgrade. The online upgrade is to use the network as the transmission medium to transmit the upgrade software. Serial port upgrade is to download the upgrade software through the serial port to realiz...
