Digital TV all-in-one upgrade method, device, medium and computer equipment

Abstract

The present invention provides a digital television all-in-one machine upgrading method and device. The method comprises the steps of: obtaining OTA (On The Air) data from a digital signal broadcast network through an OTA data inlet; employing digiboard upgrading data in the OTA data to perform upgrading of a digiboard in a digital television all-in-one machine; and employing analog board upgrading data in the OTA data to perform upgrading of an analog board in the digital television all-in-one machine. The digital television all-in-one machine upgrading method and device can stably and reliably perform OTA of the whole digital television all-in-one machine.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for upgrading a digital television integrated machine. Background technique [0002] In the set-top box industry, OTA (On The Air) is already a mature upgrade standard. The upgrade data in a custom format is delivered through the digital TV broadcasting network, and the set-top box receives the linkage upgrade information from the NIT (Network Information Table, Network Information Table), and jumps to the loader for upgrade. [0003] However, due to the immaturity of high-security TV chip technology, the current mainstream solution for digital TV all-in-ones (with both TV and digital signal decoding functions) is still a dual-board solution: a TV main chip, which realizes the basic functions of LCD TVs, called It is an analog board; another set-top box chip is responsible for digital TV signal reception and decoding output, called a digital board.

AI Technical Summary

Problems solved by technology

[0006] 1) The analog board does not support OTA upgrade, which is not convenient for operators to upgrade on a large scale

[0007] 2) The upgrade of the analog board and the upgrade of the digital board are two independent processes. If the upgrade involves two boards at the same time, and if the interaction protocol between the two boards is upgraded, there will be many problems caused by protocol mismatch during the sequential upgrade. question

Since the two USB ports are on two boards, there will be functional differences between the two USB ports, which will bring troubles to users and after-sales personnel, and will increase the hardware cost of a USB socket.

[0009] 4) The current upgrade schemes for analog boards do not have digital signatures, encryption and other security guarantee mechanisms, the cost of cracking is very low, and there is no security guarantee
