Picture/sound output equipment with caller identification and volume adjustment functions
Abstract:
A picture/sound output equipment with caller identification and volume adjustment functions comprises a main unit provided with buttons and picture/sound output hole for connection to the screen and amplifier; and an incoming-call detection circuit connecting to telephone line on one end and connecting to the main unit on the other end. The incoming-call detection circuit transforms the signals of incoming calls into visual signals and outputs the visual signals. When the picture/sound output equipment is in use and the phone rings, the signals of incoming calls will be located and displayed on the screen, thereby helps users not to miss the phone calls as they watch films.
