摘要
This invention discloses a method for upgrading software in the teleconference video terminal. It includes the steps of sending the upgrading startup information to the long-range video terminal which needed software upgrading from the local video terminal which had the upgrading software for the sake of starting the upgrading process, and vice versa; building upgrading data channel between the local terminal and the long-range terminal; communicating with the long-range terminal through said data channel from the local terminal for the sake of transmitting the upgrading software code to said long-range terminal. This invention makes use of the existing teleconference video lines of the video conference system, so it is convenience to realize long-range upgrading and reduces the maintenance cost of the terminal devices.
