Attorney, Agent or Firm:
A black and white monitoring system apparatus for use in a remote controller having a light receiver, an analog multiplexer, a signal level controller, an analog switching member, A/D converters, latches, parallel/serial converters, a control signal generator, a first oscillator, an OR gate, and a light transmitter disposed in the television set. The remote controller has a remote control signal generator, a control signal light transmitter, a remote control signal separator, a vertical driving circuit, a horizontal driving circuit, a liquid crystal monitor, a control signal generator, and second oscillator. In this system, a broadcast television picture is reproduced on a liquid crystal monitor in black and white so that the television picture can be seen on the remote controller by freely selecting a channel. |

DETAILED DESCRIPTION Accordingly, it is an object of the present invention to provide a black and white monitoring system for use in a remote controller.
Another object of the present invention is to provide a black and white monitoring system disposed in a television set and a remote controller wherein a luminance signal according to the television broadcasting program is selected and the picture of the luminance signal is possible to be reproduced on the liquid crystal monitor of a remote controller.
A further object of the present invention is to provide a black and white monitoring system which includes a vertical driving circuit, a horizontal driving circuit, and a liquid crystal monitor built in the remote controller and an analog multiplexer disposed in a television set for selecting a luminance signal of television broadcasting program by controlling the remote controller wherein a signal level of the luminance signal selected by the analog multiplexer is controlled, and thereafter, the luminance signal is sampled during a predetermined period according to a synchronizing signal of the television set and is converted into a parallel digital signal of predetermined bits.
The parallel digital signal is converted into a serial digital signal and then transmitted through a light transmitter.
The transmitted signal is received through a light receiver and is separated the serial digital signal therefrom during a predetermined period and then converted to the parallel digital signal.
The parallel digital signal is applied to the vertical driving circuit through the analog multiplexer to be displayed on the liquid crystal monitor.
Other objects and further scope of applicability of the present invention will become apparent from the detailed description given below.
It should be understood, however, that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description
