Digital television software updating system

Abstract

The invention relates to a digital television software updating system, which comprises a television host and a digital television module connected with the television host. The digital television module is connected with a corresponding port of the television host through an adapter board after being separated from the television host, the adapter board is provided with a television terminal IC and a digital terminal IC which are connected, the television terminal IC is connected with the television host, and the digital terminal IC is respectively connected with the digital television module and a communication port used for transmission update data. Users can watch television and operates when the digital television software updating system is capable of upgrading the digital television module so that the users can use the digital television software updating system conveniently. Further, the users can select different upgrading modes and operate simply, and efficiency of digital television software updating is improved effectively. Invalid software update can be controlled by controlling the issuing number of adapter boards.

Description

technical field [0001] The invention relates to a system for updating software, in particular to a system for updating digital TV software. Background technique [0002] At present, the digital TV industry is developing rapidly, and the functions of the set-top boxes are becoming more and more abundant. At the same time, digital TV all-in-ones have become more and more popular in the past two years. Since the current design of the digital TV all-in-one machine is to embed the main board of the digital TV set-top box into the TV as a module, the communication between the two parties is mainly undertaken by the serial port (such as the transmission of remote control button signals, etc.). Since the digital TV module needs to have the characteristics of low cost, easy plug-in, and easy replacement, it is usually designed on the back cover of the TV, and there is no other input device support on the digital TV module, such as receiving front panel key input. Interaction with o...

Since the digital TV module needs to have the characteristics of low cost, easy plug-in, and easy replacement, it is usually designed on the back cover of the TV, and there is no other input device support on the digital TV module, such as receiving front panel key input. Interaction with other communication interfaces

When upgrading the software of the digital TV module, the serial port upgrade is an indispensable basic function of the digital TV module. , so when the digital TV module software is updated, the serial port connected to the digital TV module cannot be used as a communication with the TV host at the same time, which makes it impossible to watch TV and other operations when the digital TV module is upgraded, affecting the user's use
