PURPOSE:To remotely control the picture quality in addition to the channel selection and sound volume, by inputting controlled outputs of the brightness, contrast, and color density from the control amount memory of the remote-control transmitting section to the controlling circuit of the digitizing processing section. CONSTITUTION:By a signal 66 of a channel selection and sound volume control switching section 69 of a remote-control transmitting section, a switch (SW) 53 is closed and a power source 50 is connected, and then, a channel selection and sound volume adjusting signal 72 is sent to a remote-control receiving circuit after it is converted 75. Moreover, the SW 53 is closed by a signal obtained by operating each switch for controlling brightness, contrast, and color density of a control SW 60, and, at the same time, a control signal 59, and a timing signal 67 are applied to a control amount memory circuit 55 and controlling outputs of brightness, contrast, and color density are sent to the remote-control receiving circuit through a P/S converting circuit 61. The output signal of the receiving circuit is inputted into a digitizing processing section of analog video signals and the picture quality processing is controlled. |
