Problems solved by technology

When the network is poor, or the terminal suddenly loses power, only a part of the effective program in the flash memory may be sintered into it, and it is not completely successful; when this incomplete program is still running after the next startup, the whole program will definitely not be able to start
As for the terminal, it has to be taken back and rewritten by the supplier, which brings a lot of inconvenience to the maintenance and upgrade of the terminal, so it is especially necessary and urgent to solve this problem

Embodiment Construction

[0019] Below in conjunction with accompanying drawing, the implementation of the present invention is described in detail as follows:

[0020] In FIG. 1 , the execution program stored in the existing flash memory space has been described in detail in "Background Technology", so it is omitted here.

[0021] In Fig. 2, the specific flash memory (flash) address allocation of the present invention, for new flash memory allocation mode, the present invention has added protection sign and a protection program area, thereby has dynamic upgrading function. The function of the protection program is also very simple. The protection program only provides the necessary interface and some network port content required for upgrading, and occupies very little space in the flash memory.

[0022] In Fig. 3, the steps of the specific startup program in the new flash memory allocation mode are as follows:

[0023] 1. First, power on and start the boot program (boot), read the value of the prote...

Abstract

A method for protecting a mode of a video conference terminal belongs to the category of communication control, and in particular relates to a method for protecting a video conference terminal in communication transmission. It adds a protection flag and a protection program area in the flash memory allocation method, and the steps of starting the program are as follows: 1. First, power on and start the boot program, read the value of the protection mode, and make a judgment whether the value is 1; 2. . If so, start the safe mode program; 3., if not, decide to start the upgrade program according to the program flag bit. Due to the adoption of the above technical solution, it has the following advantages: 1. When updating the terminals, all the terminals on the network can be dynamically upgraded with only one pc, without worrying about the influence of network failures and other failures. 2. During the dynamic upgrade process, the staff can upgrade remotely. If there are some network failures during the upgrade, due to the function of the protection program, the upgrade can be successfully realized in the end.

Description

technical field [0001] The invention belongs to the category of communication control, in particular to a method for protecting a video conference terminal in communication transmission. Background technique [0002] In the video conferencing system, the miniaturized terminal is a closed system, and its upgrade needs to be carried out through the network port at present. For the current network environment, it often happens that the upgrade fails due to network reasons. At this time, the program in the flash memory is being destroyed. If it is started from a known address, it must not be started. Go back to the manufacturer for replacement, which will cause double trouble for the manufacturer and the user. [0003] The more popular miniaturized terminal equipment now usually adopts a real-time operating system. The running program of the entire system is placed on a flash memory. When the device is powered on, the self-starting chip on the board...
