Abstract

PURPOSE:To confirm the contents of broadcast of all channels by selecting sequentially plural preset channels every time an oscillating pulse of an oscillating circuit is inputted. CONSTITUTION:A sequential channel selection start signal from a remote operating device is received by a remote control signal receiver 1, the signal is decoded by a remote control signal decoding circuit 4 to start the operation of the oscillator 3 and a preset type control signal circuit 2 is operated sequentially for the channel selection. Then, when a signal designating a desired specific channel is given from the remote control circuit, the oscillator 1 is stopped and the specific channel is selected. When a sequential channel selection stop signal is given during the sequential channel selection, the sequential channel selecting operation is stopped at a channel selected at the time. Thus, the preset station is selected sequentially by one operation of the remote controller and the contents of broadcast are confirmed, then a desired channel is selected by the remote controller further, allowing to select the desired channel.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a television receiver having a preset electronic channel selection circuit.

Conventional configuration and its problems Conventional television receivers with preset electronic channel selection circuits either directly select multiple preset channels by pressing an operation button corresponding to each channel, or Channels are selected one by one by repeatedly operating a single operation button, but in order to view all of the preset channels, you need to turn on the remote control device for the number of preset stations. It required some operations, and those operations were troublesome.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a television receiver that allows the user to check the broadcast contents of all preset channels with a simple operation.

Structure of the Invention The television receiver of the present invention includes a signal generating section that generates a sequential tuning start signal and a sequential tuning stop signal, and a signal generating section that generates a sequential tuning start signal outputted from the signal generating section. 11 @ An oscillation circuit that generates oscillation pulses at a constant cycle until the next channel selection stop F signal is output, and a plurality of preset channels are sequentially activated every time the oscillation pulse of this oscillation circuit is input. By having a configuration including a preset channel selection circuit for channel selection, it is possible to confirm the contents of all si-reset channels by a simple operation of activating a signal generation section.

DESCRIPTION OF THE EMBODIMENTS The drawing shows a block diagram of the main parts of a television receiver according to an embodiment of the present invention. In the drawings, reference numeral 1 denotes a remote control signal receiver that receives, amplifies and detects a signal from a remote control device (not shown). Reference numeral 2 denotes a preset type tuning circuit in which a plurality of channels are preset, and has a direct tuning signal input terminal a and a sequential tuning signal input terminal A. Reference numeral 3 denotes an oscillation circuit whose oscillation frequency is adjustable, which sequentially supplies oscillation pulses to the channel selection signal input terminals, and causes the preset channel selection circuit 2 to sequentially select a specific channel each time it outputs an oscillation pulse.

4 is a remote control signal decoding circuit that decodes the output signal of the remote control signal receiver 1 and determines whether it is a sequential tuning start signal, a sequential tuning stop signal, or a direct tuning signal; The preset type tuning circuit 2 starts the oscillation of the oscillation circuit 3 when it is determined that the signal is a signal, and generates oscillation pulses at constant synchronization.
When it is determined that it is the 1st station selection stop signal, the oscillation circuit 3 stops the oscillation 01 operation, and the far station window of the preset type tuning circuit 2 is activated when the oscillation is stopped. When it is determined that it is a direct tuning signal, the @oscillation operation of the oscillator @3 is stopped +l-, and the direct tuning signal of the designated channel is given to the preset tuning circuit 2 to select that channel. let it play.

In the drawing, a sequential tuning start signal from a remote control device is received by a remote control signal receiver 1, the signal is decoded by a remote control signal decoding circuit 4, and an oscillator 3 is started 413 times to create a preset tuning circuit. 2 to perform the next channel selection operation. Thereafter, when a signal designating a desired specific channel is given from the remote control device, the oscillator 3 is stopped and the specific channel is selected. When a sequential channel selection stop signal is given during sequential channel selection, the operation of sequentially selecting channels on the channel currently selected at that time is stopped.

□ With this configuration, you can sequentially tune into the preset stations and check their broadcast content with just one operation on the remote control device, and then select the desired channel using the remote control device. For example, 11@can stop the next channel selection and select the desired channel.

Effects of the Invention According to the television receiver of the present invention, presets can be made without the need for frequent complicated operations of a remote control device, unlike the conventional direct channel selection operation or sequential channel selection operation one by one. You can check the contents of all channels.
