Abstract: A display apparatus enables analog clock display with, for example, twelve numbers 1 to 12 and a pair of long and short hands. In the display apparatus, a control circuit produces instruction data for controlling an on-screen display circuit which generates color signals for displaying an analog clock image. The instruction data causes the on-screen display circuit to change the colors of the two numbers to which the long and short hands point in the analog clock image so that these two numbers are displayed in a different color from those of other ten numbers.

Abstract: An audio-visual system including a plurality of audio-visual components, and a control panel or remote control unit for applying an operating signal to each of the components. Each component performs a specified operation corresponding to the operating signal. A status detector for detecting operation status of each of the plurality of audio-visual components. A switch for switching the audio-visual components to the status required to perform the specified operations, and remote control code transmitter generates a signal to allow operation of each of the audio-visual components by converting the operating signal into a remote control code signal and transmits the remote control code signal to the audio-visual component.
