If there is no ability to display non-alphabetic characters such as N*1tt, there will be an inconvenience that this feature cannot be displayed on-screen. When this happens, a blank field appears on the screen, which is extremely inconvenient.

The present invention solves the above-mentioned problem, and aims to provide an audio-visual device that can temporarily name a feature name regardless of its expression.

Means for Solving the Problems In order to solve the above problems, the present invention provides a memory for storing a list of equipment names and function names in a group of audio and video equipment connected by a control bus line, The central remote controller has a remote control receiver, and decodes the signal from the remote control receiver and sends it to the control bus line as a command to the commander, which is the central control for the audio and video equipment group mentioned above. , receives a list of device names from the memory of each device through the control bus line, stores it in the device name list of the commander memory block of the commander, and stores it in the on-screen section on the television receiver. There is no way to write the device names in an orderly manner.

Furthermore, a device is selected using a group of keys provided on the centralized remote control in the same section corresponding to the section on the television receiver, and the selected device immediately commands a list of its function names from its own memory. When sending a list of function names in the commander's memory block, the commander memorizes them, and immediately on-screens, there are characters or symbols that the commander cannot on-screen against, based on his on-screen capabilities. In this case, the user immediately has a means of determining the characters or symbols to be displayed on-screen according to his/her own unique nomenclature.

Effect: With the above configuration, no matter what the feature name is, it can always be displayed on-screen with a temporary name, and the device can be operated.

EXAMPLE An example of the present invention will be described below with reference to the drawings.
