Method and apparatus for upgrading set-top box software

Abstract

The invention discloses a set-top box software upgrade method and a device thereof, wherein, the software upgrade method comprises the following steps: a set-top box to be upgraded is connected with an upgraded set-top box through a serial port, the set-top box to be upgraded is taken as a server and enters the working mode of the server; the set-top box to be upgraded is electrified and started, a startup message is sent to the server through the serial port, and the set-top box to be upgraded is taken as a client and enters the working mode of a client after receiving a startup response message of the server; the server packages upgrade files into serial port data packets and transmits the serial port data packets through the serial port; the client receives the serial port data packets through the serial port and carries out the application software upgrade. The invention realizes the minimum manual intervention in the serial port upgrade in the set-top boxes and provides the simple, high-efficient and reliable serial port software upgrade.

Description

technical field [0001] The invention relates to a software upgrading method, in particular to a set-top box application software upgrading method and device. Background technique [0002] With the gradual and in-depth advancement of China's digital TV overall translation, digital TV set-top boxes have entered hundreds of millions of households, bringing Chinese people unprecedented digital audio-visual enjoyment. [0003] For operators and manufacturers, a mature and reliable upgrade solution means a convenient, fast, efficient and safe operation and maintenance guarantee, and prolongs the life cycle of the set-top box as much as possible, so that users can both Enjoy the latest digital TV technology for a while, while limiting the overall operating cost of digital TV. [0004] As a terminal device for watching digital TV, the set-top box has two types of software inside: the main program of the set-top box and the upgrade control program. The running main program obtains ...

Problems solved by technology

[0006] In addition, with the increasing sales volume of set-top boxes and the increasing popularity of set-top boxes, operators are becoming more and more cautious about centralized large-scale over-the-air upgrades, because once there is a problem with the upgrade, the set-top boxes may be damaged, which may cause user Dissatisfaction; at the same time, for the sake of operational safety, operators also put forward higher security requirements for over-the-air upgrades, and often formulate strict encryption and signature mechanisms for upgrade data packets. Even set-top box manufacturers cannot privately make upgrade streams to upgrade set-top box software

In this way, set-top box manufacturers and maintenance personnel can only rely on serial port upgrades, and the characteristics of serial port upgrade point-to-point communication and serial port communication rate are low, resulting in low efficiency of serial port upgrades, and an upgrade of 8 megabytes of data often takes half hours to complete
