The viewer operates the key input unit 10 or the remote controller 20 to view a broadcasting channel of a television to be watched in a state where power is applied. When selected, the microcomputer that recognizes the signal generates a preset voltage corresponding to the tuner and applies it to the tuner. Accordingly, the tuner receives the broadcast signal of the channel selected by the preset voltage generated by the microcomputer from the free space through the antenna ANT and inputs the broadcast signal to an image processor and an audio processor (not shown).

Thus, the image processor 40 processes only the video signal from the broadcast signal input from the tuner by the control signal of the microcomputer and inputs the processed video signal into the mixer. OSD (On Screen Display) generation unit 60 receives the character information output from the microprocessor is input to the mixer to convert the corresponding character image to output the image. In the mixer, the image signal processed by the image processor and the character image information output from the ODS generator are synthesized and input to the image amplifying unit. Then, since the image amplification unit amplifies the image signal to a level that can be displayed on the CRT screen and supplies it to the CRT, the image signal transmitted from the broadcasting station to the free space is displayed on the screen so that the viewer can watch the image signal.

However, in a television operating as described above, viewers often want to know the broadcast order of the day. In the past, when a viewer wants to satisfy such a desire, the viewer may refer to a broadcast order guide of a newspaper or a television guide. If you look at the broadcast sequence guide screen sent by the broadcast station at the start time, or when the broadcast station sends data indicating the broadcast order to the text line, this could be seen. However, the method of loading data on a broadcast order guide screen or a text line has a disadvantage that can only be seen by sending a signal from a broadcasting station. Also, in order to solve this problem, a method of transmitting a broadcast order by a broadcasting station was created, but there was a problem in that a signal promised between both parties and a device capable of decoding the same were needed.

An object of the present invention for solving the problems described above is to save the broadcast order information for each channel in the memory using a screen that guides the broadcast time of the day at the time when the TV broadcast starts, the viewer A television receiver having a broadcast order guide function that allows a television receiver to view a broadcast order guide screen stored in a memory by simple key input when watching a broadcast order.
