Description
Technical Field
The invention relates to the technical field of communication, in particular to a method and a device for upgrading a digital television all-in-one machine.
Background
In The set-top box industry, OTA (On The Air upgrade) is already a mature upgrade standard. The method comprises the steps of issuing upgrading data in a custom format through a digital television broadcasting Network, receiving linking upgrading Information from an NIT (Network Information Table) by a set-top box, and jumping to a loader for upgrading.
However, as the technology of the high-security television chip is not mature enough, the mainstream scheme of the digital television all-in-one machine (having the functions of both a television and a digital signal decoding) is still a double-board scheme: the television main chip realizes the basic functions of the liquid crystal television and is called as an analog board; the other set-top box chip is responsible for receiving and decoding the digital television signals and is called a digital board. The digital board is upgraded by a mature OTA (over the air) upgrading scheme, namely a set-top box OTA scheme. For the upgrade of the analog board, the traditional liquid crystal television product does not have the requirement of large-scale upgrade after the product is sold, so the analog board only supports the upgrade of the USB flash disk in the traditional television scheme. Although this upgrading method is sufficient for after-sales and maintenance, it is necessary for the digital tv operators to upgrade the digital tv product in a large scale in many application scenarios as the demand increases.
In the existing upgrading technology of the digital television all-in-one machine, an analog board and a digital board are upgraded separately. The traditional digital board upgrading scheme can be upgraded by using OTA (over the air) and can also be upgraded by using USB (universal serial bus). The OTA upgrading is suitable for operators to carry out large-scale user software upgrading: the upgrading software of the digital board part is made into an upgrading ts code stream after passing through a streaming tool, the upgrading ts code stream is multiplexed into a program code stream by the front end and is sent to the digital board end through a digital television broadcasting network, and the digital board judges that the upgrading conditions are met and automatically triggers the automatic upgrading. The USB upgrading is suitable for the maintenance of a single field digital television integrated machine or small-scale upgrading scenes such as test software upgrading and the like. The upgrading scheme of the traditional analog board adopts USB upgrading, an executable program compiled is made into a USB upgrading file through a analog board streaming tool, the USB upgrading file is copied to a USB flash disk and is connected to a USB interface connected to a template, and USB upgrading is triggered through menu options.
However, the technology of separately upgrading the analog board and the digital board of the digital television all-in-one machine has the following disadvantages:
1) the analog board does not support OTA upgrading, and is not convenient for large-scale upgrading of operators.
2) The upgrading of the analog board and the upgrading of the digital board are two independent processes, if the upgrading simultaneously involves two boards, and if the interactive protocols between the two boards are upgraded, a plurality of problems caused by protocol mismatching exist in the process of upgrading in sequence.
3) If both the digital board and the analog board need to support USB upgrade, USB flash disk interfaces need to be reserved on both boards. Because the two USB ports are respectively arranged on the two boards, the two USB ports have functional difference, which brings trouble to users and after-sales personnel and increases the hardware cost of one USB socket.
4) The existing upgrading scheme of the analog board has no security guarantee mechanisms such as digital signature and encryption, so that the cracking cost is low and the security guarantee is lacked.
