  Reference numeral 15 denotes a remote control light receiving unit. The television receiver 2 receives an operation signal of the remote control 3 from the remote control light receiving unit 15 and executes channel switching and the like as will be described later. Reference numeral 16 denotes a microcomputer (hereinafter referred to as a microcomputer) that controls the entire television receiver 2.

Next, the operation of the first exemplary embodiment of the present invention will be described with reference to FIG.
First, when the user of the television receiver 2 operates the channel button of the remote controller 3 toward the remote control light receiving unit 15, the operation signal is transmitted from the remote control 3 to the remote control light receiving unit 15 as an infrared signal. When the remote control light receiving unit 15 receives this signal, this signal is converted into a voltage by the remote control light receiving unit 15 and transmitted to the microcomputer 16 as an electrical signal. In step S1, the microcomputer 16 receives this signal from the remote control light receiving unit 15 and detects that the channel button of the remote control 3 has been pressed.

  The microcomputer 16 decodes the received code signal and executes processing in accordance with the control content received from the remote controller 3. In step S2, since the channel button is pressed by the remote controller 3, the channel corresponding to the channel is selected from the currently viewed media.

  In the next step S3, video display processing of the selected channel is executed. For channel selection in the same media, the microcomputer 16 sends a channel switching signal to each tuner of the terrestrial analog broadcast tuner 4, the terrestrial digital broadcast tuner 5, the BS digital broadcast tuner 6, and the CS digital broadcast tuner 7. This is done by selecting the channel so that the tuner to which the transmission and switching signal is sent receives the signal in the frequency band of the desired channel.

  In step S4, the time during which the channel button of the remote controller 3 is pressed is measured. In the embodiment of the present invention, when it is detected that the channel button of the remote controller 3 is pressed for a predetermined time or longer, the operation is performed so as to switch the media. In the example of FIG. 3, the predetermined time is set to 1 second, and if it is determined in step S4 that the channel button of the remote controller 3 has been pressed for 1 second or longer, the process proceeds to step S5. If it is less than 1 second, the process proceeds to step S9, where the channel selection is performed in step S2, and the display of the final channel selection channel subjected to the video display process in step S3 is maintained.

The media is switched by sending a command signal from the microcomputer 16 to the selector switch (SW1) 13 and the selector switch (SW2) 10 shown in FIG. 2, and switching the selector switch (SW1) 13 and selector switch (SW2) 10. Is called. A change-over switch (SW1) 13 is a selection switch for switching digital signals of the terrestrial digital broadcast tuner 5, the BS digital broadcast tuner 6, and the CS digital broadcast tuner 7. Also, selector switch (SW2) 10 is a selection switch for switching digital video signal a ₆ from the digital video signal a ₂ and a digital broadcast decoder 14 where the terrestrial analog broadcast tuner 4 to digital conversion. For example, when the media is switched to terrestrial analog broadcasting, the digital video signal a ₂ may be selected by the changeover switch (SW2) 10. Further, for example, when switching the media to the BS digital broadcast switches the changeover switch (SW1) 13 to select a signal from the BS digital broadcast tuner 6, the digital video signal _{a 6} by changeover switch (SW2) 10 Just choose.

  When the process proceeds from step S4 to step S5, it is determined in step S5 whether the corresponding channel of the medium to be switched next is a broadcast channel. The media switching order to be switched next may be set and stored in advance.

  If the channel is not broadcasted, the process proceeds to step S10, the medium is skipped, the process proceeds to step S4, and the processing from step S4 onward is continued. In this case, it is checked again in step S4 whether or not the pressing time of the remote control channel button has been 1 second or longer. However, if it has passed through step S10, the channel button of the remote control 3 has been pressed for 1 second or longer. Then, the broadcasting status of the corresponding channel of the media next to the media skipped earlier is checked.

  When a channel that is not broadcast is detected continuously in step S5, step S10, step S4, and step S5 are repeated until a broadcast channel is detected. In this case, channels of media that are not broadcast are skipped one after another. In addition to the program currently being viewed, if the same channel on other media is not being broadcast, the display of the program that is currently being viewed will be maintained after returning to the original state.

  More specifically, the channel detection of media that is not being broadcast can be performed by transmitting this detection information to the microcomputer 16 when the IP conversion / RGB processor 11 detects a mute screen. Alternatively, when the information stored in the EPG memory of the digital broadcast decoder 14 and the information stored in the correspondence relationship between the remote control channel buttons and the information that the channel is not registered or the broadcast is not started are detected, the detected information is used as the microcomputer 16. Can be done by sending to

  If it is determined in step S5 that the channel is broadcast, the process proceeds to step S6 to switch to the next media channel. In step S6, the next media channel is selected. Next, the process proceeds to step S7, and video display processing of the selected channel is performed.

  Furthermore, it progresses to step S8 and it is checked whether the channel button is pushed. If the channel button is not pressed, the display of the finally selected channel is maintained. If the channel button is pressed in step S8, the process proceeds to step S4, and the processes after step S4 are continued.

  As is apparent from the above description of the operation, according to the first embodiment, the channel switching operation of the video device of the multi-channel input method can be performed only by pressing the channel button of the remote control for a predetermined time or longer. It is simple and can be done in a short time.

(Second Embodiment)
In the first embodiment, it is checked in step S4 whether or not the channel button pressing time of the remote control 3 is 1 second or more of the predetermined time. Instead, the same channel button as the channel currently being viewed is pressed. The present invention can be carried out even if it is detected.

  FIG. 4 is a flowchart for explaining the control operation of the second embodiment of the present invention.

  First, when the user of the television receiver 2 operates the channel button of the remote controller 3 toward the remote control light receiving unit 15, the operation signal is transmitted from the remote control 3 to the remote control light receiving unit 15 as an infrared signal. When the remote control light receiving unit 15 receives this signal, this signal is converted into a voltage by the remote control light receiving unit 15 and transmitted to the microcomputer 16 as an electrical signal. In step S11, the microcomputer 16 receives this signal from the remote control light receiving unit 15 and detects that the channel button of the remote control 3 has been pressed.

  The microcomputer 16 decodes the received code signal and executes processing in accordance with the control content received from the remote controller 3. In step S12, it is checked whether or not the pressed channel button of the remote controller 3 is the same as the previous channel button. If it is determined that a channel button different from the previous one has been pressed, in step S19, the channel corresponding to that channel is selected from the currently viewed media. In the next step S20, the video display process of the selected channel is executed, and the process proceeds to step S17 to maintain the display of the final selected channel. As in the first embodiment, the microcomputer 16 uses the terrestrial analog broadcast tuner 4, the terrestrial digital broadcast tuner 5, the BS digital broadcast tuner 6, and the CS digital broadcast for channel selection in the same medium. This is performed by sending a channel switching signal to each tuner of the tuner 7.

  Next, when it is determined in step S12 that the same channel button as the previous one has been pressed, the process proceeds to step S13, and it is determined whether or not the media of the channel to be switched next is being broadcast. If the channel is not broadcast, the process proceeds to step S18, the medium is skipped, and the process proceeds to step S13 to continue the process of checking the next medium.

  If it is determined in step S13 that the channel is broadcast, the process proceeds to step S14 to switch to the next media channel. In step S14, the next media channel is selected. Next, the process proceeds to step S15 to perform video display processing for the selected channel.

Furthermore, it progresses to step S16 and it is checked whether the channel button is pushed. If the channel button is not pressed, the display of the finally selected channel is maintained.
If the channel button has been pressed in step S16, the process proceeds to step S12, and the processes after step S12 are continued.

  Also in the second embodiment, as in the first embodiment, media switching is performed by sending a command signal from the microcomputer 16 to the changeover switch (SW1) 13 and changeover switch (SW2) 10 shown in FIG. The changeover switch (SW1) 13 and the changeover switch (SW2) 10 are switched.

  Also in the second embodiment, similarly to the first embodiment, the channel detection of media that is not broadcasted is performed when the IP conversion / RGB processor 11 detects a mute screen. The detection information can be transmitted to the microcomputer 16. Alternatively, when the information stored in the EPG memory of the digital broadcast decoder 14 and the information stored in the correspondence relationship between the remote control channel buttons and the information that the channel is not registered or the broadcast is not started are detected, the detected information is used as the microcomputer 16. Can be done by sending to

In the above-described embodiment, the case where there is one analog signal broadcast medium and a plurality of digital signal broadcast media has been described, but the present invention can be applied even when there are a plurality of analog signal broadcast media. In this case, a switch corresponding to the changeover switch (SW1) 13 is inserted between the terrestrial analog tuner 4 and the analog broadcast decoder 8.
The media search order at the time of channel switching may be arbitrarily set.

  As is apparent from the above description of the operation, according to the second embodiment, the channel switching operation of the video device of the multi-channel input method is simple and short by only operating the same channel button as the previous time. Can be done in time.

  As mentioned above, although embodiment of this invention was described concretely, this invention is not limited to the said embodiment, It can change and implement in the range which does not change the summary of this invention.

  The present invention can be widely used for channel switching operation of a multi-channel input type video apparatus.
