Device showing percentage of scheduled watch time

The present invention relates to an apparatus for displaying a broadcast progress by converting a predetermined viewing time as a percentage by using an OSD (On Screen Display) displayed on a TV screen in a TV. That is, when a viewer selects a viewing time reservation button provided on the remote controller, a text screen using an OSD is displayed, and the viewer can set a desired time zone every hour and a specific time through the text screen, Apparatus for displaying scheduled watching time, which enables the user to set a specific time for the broadcast so that the broadcast progress can be converted into a percentage and displayed as a text or bar graph to visually check the broadcast progress. with percentage).

In general, a broadcast program of a television receives a high frequency signal transmitted from a broadcasting station through an antenna and displays it on a screen. The color light of a subject sent to an image pickup tube is divided into RGB signals and made into YIQ signals in a matrix circuit. In order to easily separate the YIQ signal from the receiving side, the I and Q signals pass through a balance modulator, respectively, to be changed in phase, and then transmitted by mixing color burst signals, horizontal / vertical synchronization signals, and voice signals. do. The transmitted composite video signal is received through an antenna and amplified through a high frequency amplification step to increase sensitivity and selectivity, improve S / N ratio, and increase output. In addition, YIQ signals are obtained through a series of processes such as image detection step and band amplification step, and these signals are synthesized at a constant ratio and reproduced as RGB signals, respectively, and formed into scanning beams by RGB electron guns, respectively. The image transmitted from the transmitting side is displayed while scanning the RGB fluorescent surface past the aperture grille. In addition, all programs that are displayed and broadcast as described above are broadcasted at predetermined time slots in the broadcasting station. In order to confirm the end time of the viewing broadcast program, a viewer who is watching a particular broadcast among the broadcasting programs such as drama, movie, and news broadcasted by the predetermined time zone has to check the clock or check the broadcasting time of the regular broadcasting program. There was this.

The present invention has been invented to solve the above problems, and an object of the present invention is to set the broadcast program by setting the hourly, specific time and broadcast time of the regular broadcast program on the TV screen by utilizing the OSD function of the TV screen. The present invention provides a device for displaying a scheduled viewing time as a percentage so that the viewer can visually check the scheduled viewing time for the viewer by converting it into a percentage and displaying it in text or graphics.
