Abstract

The invention belongs to the technical field of the upgrading of software of a set-top box and discloses a method for packaging upgrading software of the set-top box, comprising the following specific steps: storing upgrading data into a section through an upgrading data descriptor, and carrying out upgrading flow packaging by taking a file group as a unit, wherein each file group comprises all the upgrading data needed by one type of set-top box, each upgrading file corresponds to an upgrading area on a certain flash equipment and is divided into a plurality of blocks in an upgrading flow, and each block is stored in one section in one upgrading flow. The upgrading data comprises downloading service information, downloading indication information and downloading data block information. The method for packaging the upgrading software of the set-top box supports a plurality of flash equipment and a plurality of partitions, consumes fewer resources and ensures the rapid and flexible software upgrading.

Description

technical field [0001] The invention relates to the field of digital TV set-top boxes, in particular to a method for packaging set-top box upgrade software. Background technique [0002] With the development of the global digital TV industry, the functions of digital TV set-top boxes have become more and more powerful, and they are getting closer to computers. Internet access and interactive games have also become popular on set-top boxes. Linux operating systems are more and more widely used in set-top boxes. The software capacity of the set-top box is also increasing. However, the capacity of a commonly used flash device has begun to face shortage. Set-top boxes with multiple flash devices will become a trend in the future. The more Flash devices are used, the larger the software will be, which also makes it inconvenient to upgrade the software. The traditional upgrade method can usually only be upgraded for one flash device, and only one upgrade file can be sent for up...
