An LCD TV is essentially a display device that requires a signal source to provide image signals to display a variety of images. LCD TVs and signal sources must be connected and transmitted through interfaces. Different signal sources have different interface types. Therefore, LCD TVs are usually equipped with multiple sets of different interfaces for users to choose from.
Common interfaces of LCD TVs include AV compound video interfaces, S-terminal interfaces, chromatic aberration interfaces, V

in the development environment. The physical path of FCKeditor is consistent with that of the production environment;
To upgrade FCKeditor, you only need to put the new version of FCKeditor in the directory of the corresponding version number and modify the configuration. In this way, different users may encounter different errors due to the client cache of static resources;
You can see the version number of your FCKeditor.

Why cables anyhow?
Why not VGA or composite video cable?
What's the difference between digital cables?
Do I need expensive cables?
So which digital cable is best?

MBean (Managed Bean)
is typically a Java class that provides an interface that enables the class to have functionality that can be managed (successfully registered on the server). It usually represents a program that we want to actually manage, or a device, and so on, which we encapsulate with the specification of Mbean.
