Abstract
A method for processing multimedia signal abnormity and a display apparatus are provided. The method includes the following. Whether a multimedia signal received through a multimedia signal input interface of the display apparatus is abnormal is determined. A preset image signal is output to a CPU of the display apparatus when the received multimedia signal is abnormal, such that the preset image signal is output to a display screen of the display apparatus through the CPU, where the preset image signal contains a prompt message of a multimedia signal abnormality.
Claims20
A method for processing multimedia signal abnormity, the method being applied to a display apparatus, the display apparatus comprising a multiple signal input interface capable of being coupled with an external device and receiving a multimedia signal from the external device, the method comprising:
- determining whether a multimedia signal received through the multimedia signal input interface is abnormal;
- and
- outputting a preset image signal to a central processing unit (CPU) of the display apparatus based on a determination that the multimedia signal received through the multimedia signal input interface is abnormal, such that the preset image signal is output to a display screen through the CPU, the preset image signal containing a prompt message of a multimedia signal abnormity.
A display apparatus, comprising:
- a multimedia signal input interface;
- a central processing unit (CPU);
- a display screen;
- and
- a multimedia signal processor coupled between the multimedia signal input interface and the CPU, and configured to:
- determine whether a multimedia signal received through the multimedia signal input interface is abnormal;
- and
- output a preset image signal to the CPU based on a determination that the multimedia signal received through the multimedia signal input interface is abnormal, such that the preset image signal is output to the display screen through the CPU, the preset image signal containing a prompt message of a multimedia signal abnormity.
A non-transitory computer-readable storage medium storing at least one computer executable instruction which, when executed by a multimedia signal processor of a display apparatus, causes the multimedia signal processor to carry out actions, comprising:
- determining whether a multimedia signal received through a multimedia signal input interface of the display apparatus is abnormal;
- and
- outputting a preset image signal to a central processing unit (CPU) of the display apparatus based on a determination that the multimedia signal received through the multimedia signal input interface is abnormal, such that the preset image signal is output to a display screen through the CPU, the preset image signal containing a prompt message of a multimedia signal abnormity.
