Abstract
A method for controlling analog TV signal output in a computer system. First, the analog TV signal output port is disabled when the computer system boots. A signal output control interface is provided to the DVD play device to control the analog TV signal output port. When the DVD play application is turned on, the analog TV signal output port is opened by the DVD play device through the signal output control interface. A signal protection procedure is driven simultaneously when the DVD play device starts. Before the DVD play device finishes, the analog TV signal output port is disabled by the signal output control interface and the DVD session is concluded.
