  The RAM 234 temporarily holds data generated by the CPU 220. The RAM 234 temporarily holds a program executed by the CPU 220 in an executable format.

  In the data processing unit 240, the demultiplexer 244 performs preprocessing such as error correction and descrambling on the transport stream (TS) transmitted from the tuner 140.

  Further, the demultiplexer 244 temporarily stores the input transport stream (TS) in the buffer 255. The demultiplexer 244 reads the temporarily stored transport stream (TS) from the buffer 255 for each preset unit. The reading order is set in advance, for example, but is not limited thereto. Each data may be read in the order stored in the buffer 255.

  The demultiplexer 244 separates the data of a plurality of broadcast programs multiplexed in the transport stream (TS) into MPEG data and audio data corresponding to the channel designated by the CPU 220, and the separated MPEG data Send to video decoder 246. In addition, the demultiplexer 244 sends the audio data to the audio decoder 260.

  The video decoder 246 executes decompression processing conforming to the MPEG compression encoding method on the MPEG format video data, and sends the video data obtained by the processing to the video signal generation unit 252.

  The video signal generation unit 252 adds data for OSD (On Screen Display) to the data output from the video decoder 246 to generate a video signal for display. The video signal generation unit 252 sends the generated video signal to the display driver 254.

  On the other hand, the audio decoder 260 executes a predetermined expansion process conforming to the MPEG compression encoding method on the MPEG audio data output from the demultiplexer 244. The audio decoder 260 sends the audio data obtained by the processing to the audio signal generation unit 262.

  The audio signal generation unit 262 performs D / A conversion on the data sent from the audio decoder 262 and sends an analog audio signal to the amplifier 264.

  The amplifier 264 amplifies the audio signal sent from the audio signal generation unit 262 based on a command from the CPU 220, and sends the amplified signal to the speaker 266. The speaker 266 outputs sound based on the signal. The speaker 266 may be a stereo type or a monaural speaker.

  In one aspect, CPU 220 is configured to accept an input for associating the empty switch, the numeric key, and the operation of television 100 in the setting mode of television 100.

  In another aspect, the CPU 220 switches the operation mode to the setting mode based on a control signal from the remote control device 300 while the program is being displayed on the television 100, and the remote controller is associated with the empty switch and the numeric key. When the control signal transmitted from the apparatus 300 is received, the empty switch, the numeric key, and the program are associated with each other and stored in the flash memory 230.

  In another aspect, the CPU 220 switches the operation mode to the setting mode based on a control signal from the remote control device 300 while receiving a program on the television 100, and associates the empty switch with the numeric key so that the remote control device can be associated. When the control signal transmitted from 300 is received, the empty switch, the numeric key, and the image quality mode for displaying the program are associated with each other and stored in the flash memory 230.

  In yet another aspect, the CPU 220 switches the operation mode to the setting mode based on a control signal from the remote control device 300 during reception of the program on the television 100, and also associates the empty switch with the numeric key. When a control signal transmitted from 300 and a timer time (for example, time until power-off, power-on time, etc.) are received, an empty switch, a numeric key, and the timer time are associated with each other and stored in flash memory 230. It is configured.

  In the present embodiment, the idle switch may include any one or more of a “return” key (so-called back key), a clear key, and a “decision” key (also referred to as “confirmation” key, return key). However, it is not limited to these. As described above, the idle switch may be a switch that transmits a signal that is not accepted as an instruction to change the function of the television 100 when a program is displayed. Further, the configuration of the switch is not limited to a touch panel, a button, or the like. Any configuration that can accept input is acceptable.

  With reference to FIG. 3, remote control device 300 according to the present embodiment will be described. FIG. 3 is a diagram showing the appearance of remote control device 300. Remote control device 300 includes a plurality of switches for accepting operations by a user of television 100. The plurality of switches may include, for example, a numeric key 310, a “back” key 320, a clear key 330, and a decision key 340.

  While the television 100 is displaying a broadcast program, the numeric key 310 accepts an operation by the user and transmits a signal corresponding to the operated number. The television 100 switches channels according to the operation. On the other hand, when the user operates, for example, the “return” key 320, the clear key 330, or the enter key 340 while the TV 100 is displaying a program, the remote control device 300 transmits a signal corresponding to the operation. However, television 100 does not accept control signals transmitted based on these switches as signals for controlling operations.

  In the present embodiment, after the user operates any one of the “return” key 320, the clear key 330, or the enter key 340 that functions as an empty switch, any one of the numeric keys 310 is set within a predetermined time period. When operated, remote control device 300 transmits a control signal corresponding to each operation. When the television 100 receives these control signals, the television 100 operates based on the settings defined by the user as a combination of the two control signals. The time measurement is performed by, for example, a timer function of the CPU 220, a pulse count, or the like, but is not limited thereto. Any mode capable of measuring the interval between these operations may be used.

[data structure]
With reference to FIG. 4, the data structure of television 100 according to the present embodiment will be described. FIG. 4 is a diagram conceptually showing one mode of data storage in flash memory 230.

  The flash memory 230 stores favorites 131 and definition information 132. The favorite 131 is information registered by the user of the television 100. The favorite 131 includes a group 410, a number 412, and a channel 414. A group 410 is defined to group a plurality of settings. The number 412 identifies the item set by the user in that group 410. Channel 414 identifies the channel specifically selected by the user. For example, when the user selects the channel “2” for the number 412 for the number “1” in the group 410, the channel “ITV” is selected. In this way, even if there are many digital television broadcast channels (for example, 100 or more), the user can easily select the channels.

  The definition information 132 includes an empty switch 420, a numeric key 422, and a function 424. The idle switch 420 identifies a key to which a definition for defining the operation of the television 100 is assigned. In the example shown in FIG. 4, the “return” key and the “decision” key are used, but other switches may be used as empty switches.

  The numeric key 422 is associated with the empty switch 420. The numeric key 422 is selected from numeric buttons (for example, 0 to 9) constituting the numeric key 310 (FIG. 3) provided in the remote control device 300. Function 424 identifies the specific function associated with the empty switch 420 and the numeric key 422. For example, the definition set by the numeric button “1” for the “return” key indicates “selecting a favorite (group 1) BBC”.

  That is, when the television 100 detects the operation of the “return” key and the operation of the numeric button “1” within a predetermined time period, the CPU 220 causes the tuner 140 to select a channel. As a result, a combination of an empty switch that is not used in the normal operation mode (for example, the “return” key) and a switch that is used to accept another command in the normal operation mode (numeric button “1”) Can accept various operations.

[Control structure]
With reference to FIG. 5 and FIG. 6, the control structure of television 100 according to the present embodiment will be described. FIG. 5 is a flowchart showing a part of a series of processing executed by CPU 220 for registering the definition.

  In step S510, CPU 220 of television 100 switches the operation mode of television 100 from the standard mode to the setting mode. Here, the standard mode refers to a normal state in which a program can be viewed on the television 100. The setting mode refers to a mode in which parameters that define the operation of the television 100 can be set. In step S520, CPU 220 detects that the function assignment setting has been selected from the menu displayed on display 160, based on the signal from input I / F 216.

  In step S530, CPU 220 preliminarily outputs a control signal based on pressing of “return” key 320 of remote controller 300 and a control signal based on pressing of numeric button “1” based on a signal from light receiver 212. Detects reception within a set time.

  In step S540, CPU 220 detects selection of an assigned channel, an image quality mode, and other functions. The target to be selected is, for example, information on the favorite 131 already registered in the flash memory 230. The favorite 131 includes specific channel settings, image quality mode settings, timer time settings, and other setting items that can be customized by the user of the television 100.

  In step S550, CPU 220 associates the numeric key (for example, numeric button “1”) with the selected function (for example, selects BBC of “favorite” group 1) and stores it in flash memory 230. As a result, for example, as shown in FIG. 4, the association of the “return” key, the numeric key button (1), and the function (selecting the BBC of the favorite (group 1)) with respect to the empty switch 420 is realized. When the user performs other associations, the process shown in FIG. 5 is repeated.

  FIG. 6 is a flowchart showing a part of a series of processes controlled by CPU 220 based on the definition set by the process shown in FIG.

  In step S610, CPU 220 detects reception of a control signal based on pressing of “return” key 320. In step S620, CPU 220 starts measuring the time that has elapsed since reception of the control signal.

  In step S630, CPU 220 detects reception of a control signal based on pressing of any number constituting numeric key 310. In step S640, CPU 220 determines whether or not the interval between pressing “return” key 320 and pressing numeric key 310 is within a predetermined time. When CPU 220 determines that the interval is within a certain time (YES in step S640), CPU 220 switches control to step S650. If not (NO in step S640), CPU 220 switches control to step S660.

  In step S650, CPU 220 executes a function (selecting a favorite (group 1) BBC) associated with “return” key 320 and numeric key 310 (for example, numeral 1).

  In step S660, CPU 220 selects a channel based on number key 310 (for example, number “1”).

[Display mode]
With reference to FIG. 7, the display mode of the screen by television 100 according to the present embodiment will be described. FIG. 7 is a diagram showing channel display of display 160 that is switched according to the operation of remote control device 300.

  As shown in the screen (A), it is assumed that the display 160 of the television 100 displays a 4-channel program. In this state, when the user presses the number “1” with respect to the number key 310 of the remote controller 300, the display 160 starts from the display of four channels as shown in the screen (B) as a normal operation. Switches to the 1 channel display. When the user continuously presses the “return” key 320 or other empty switch and the numeric button “1”, and the interval between the presses is longer than a predetermined time, the television 100 Ignores the control signal of the empty switch and accepts only pressing of the numeric button “1”. Also in this case, as shown in the screen (B), the display 160 is switched from the 4-channel display to the 1-channel display.

  On the other hand, when the user continuously presses the “return” key 320 and the number “1” and the interval between the presses is within a predetermined time, the television 100 displays the “return” key 320. A control signal based on the depression is accepted as an effective control signal. In this case, a function specified based on the two control signals (for example, “select a favorite (group 1) BBC”) is executed. As a result, as shown in the screen (C), the display on the display 160 is switched from the 4th channel to the BBC channel.

  As described above, an empty switch (for example, a “return” key, a determination key, a clear key, and the like) of the remote controller 300 that is not used while the television 100 according to the present embodiment is displaying a program and numeric keys are displayed. When the operation is continued within a predetermined time period, the television 100 determines that the combination of the operation of the empty switch and the operation of the numeric keys is the input of a new command, and determines that combination. Perform the assigned function. Specifically, execution of a function that requires three or more operations (selection of a specific registered channel, setting of an operation mode of the television 100, etc.) is performed twice (= operation of an empty switch and a number). It can be realized by key operation). As a result, the number of operations required by the user is reduced, and convenience related to the operation of the television 100 is improved. For example, complicated operations can be executed in a short time. Further, it is not necessary to increase the number of switches of the remote controller 300 more than necessary.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
