Description
Technical Field

Common means include printing through serial port output, online debugging by JTAG and the like, reading chip internal registers, tracking software breakpoints, and the like.
Generally speaking, for a tested system with audio/video output, an engineer needs to additionally configure external devices such as a television, a display, a sound box and the like for system debugging; however, these general external devices (such as a television, a display, etc.) cannot directly cooperate with the debugging actions of an engineer, and there is no way to set triggering conditions and grab corresponding sites according to the requirements of the engineer.
The existing means are mature and skilled for engineers to use, but the following defects exist:
1) the debugging tool and the printing information are attached, the system is not closest to a real use scene, and the debugging means is that a system variable is introduced into the system, namely the system with debugging has no problem, the real system does not have problem and the system with debugging has problem, and the real system does not have problem;
2) the printing and debugging tools can only grab the internal site of the system and cannot store the external site of the system. Taking a multimedia player as an example, a printing tool and a debugging tool cannot observe a picture when a problem occurs, and the existing television, display screen and the like can only observe the phenomenon after the problem occurs in the system, and cannot know the situation (such as screen splash and blockage) occurring before the problem occurs; the time point of the external site cannot be matched with the time point of the internal site by the existing means;
3) when some external signals need to be converted, a conversion circuit or conversion equipment is additionally added (for example, a platform carried by an engineer is an HDMI output, but if the external equipment needs to support LVDS, a hardware device or a hardware circuit for converting the HDMI into the LVDS is needed).
A typical test system needs to configure a television, a computer monitor, and a power supply at the same time to complete the entire test, but generally cannot record the picture of the system under test, and further cannot determine the time point when the picture is abnormal.
