Thus, the user sets the genre to be assigned to each numeric button 13 and a plurality of channels belonging to the genre together with the priority order.

FIG. 10 shows, for example, that the user has finished the channel / priority setting process in the channel setting screens of FIGS. 8 and 9, and a genre is assigned to the numeric button 13, and among the channels belonging to the genre, the numeric button 13 It is a figure which illustrates the channel setting screen by which all the channels allocated to are displayed on the list L2 with the priority order. In the channel setting screen of FIG. 10, the number button “3” 13 is associated with the genre “sports”, and the number button “3” 13 has “CS210” belonging to the genre “sports” as the first priority channel. “CS216” is assigned as the second priority channel, “CS213” is assigned as the third priority channel, and “CS211” is assigned as the fourth priority channel.
The CPU 311 stores a plurality of channels assigned to the numeric buttons 13 by the channel / priority setting processing in the channel setting screens of FIGS. 8 to 10 in the setting memory 314a together with the priority order of each channel.

  11 shows a plurality of channels assigned to each numeric button 13 by the channel / priority setting process in the terrestrial digital broadcasting of FIGS. 5 to 7 and the channel / priority setting process in the CS digital broadcasting of FIGS. It is a figure which illustrates the setting memory 314a which memorize | stores a channel with a priority.

  The first channel selection program 315b is, for example, a channel / priority setting program as priority setting means among a plurality of channels assigned to the numeric button 13 based on a short press operation of the numeric button 13 to the CPU 311. This is a program for realizing the function of selecting the channel with the highest priority set by 315a.

  Specifically, the CPU 311 monitors a user instruction operation in the remote control device 1 based on a remote control signal input via the remote control signal light receiving unit 21. When a pressing operation of the numeric button 13 to which a plurality of channels are assigned is performed, the CPU 311 counts the time during which the numeric button 13 is pressed, and the pressing operation is a short pressing operation (for example, less than 2 seconds). Or a long press operation (for example, a continuous press operation for 2 seconds or more). If it is determined that the operation is a short press operation, the highest-priority channel assigned to the number button 13 that has been short-pressed is read from the setting memory 314a corresponding to the currently switched broadcast type, and is sent to the tuner 23. Then, a control signal for instructing the channel selection of the highest priority channel associated with the channel that has been short-pressed is output, and broadcast data of this channel is received.

For example, when the numeric button “8” 13 to which “081” is assigned as the highest priority channel is pressed for a short time in the state of switching to terrestrial digital broadcasting, the CPU 311 causes the tuner 23 to set “081”. Channel selection is instructed, and broadcast data of terrestrial digital broadcast “081” is received.
Further, for example, when the number button “3” 13 to which “CS210” belonging to the genre “sports” is assigned as the highest priority channel in a state where the switching to CS digital broadcasting is performed, the CPU 311 The tuner 23 is instructed to select “CS210” and receives broadcast data of the CS digital broadcast “CS210”.
The CPU 311 functions as a first channel selection unit by executing the first channel selection program 315b.

  The second channel selection program 315c, for example, allows the CPU 311 to select a plurality of channels assigned to the numeric button 13 while the numeric button 13 is being pressed for a long time based on the long press operation of the numeric button 13. This is a program for realizing a function of selecting in sequence and selecting a channel selected when the long press operation is completed.

Specifically, the CPU 311 monitors a user instruction operation in the remote control device 1 based on a remote control signal input via the remote control signal light receiving unit 21. When a pressing operation of the numeric button 13 to which a plurality of channels are assigned is performed, the CPU 311 counts the time during which the numeric button 13 is pressed, and the pressing operation is a short pressing operation (for example, less than 2 seconds). Or a long press operation (for example, a continuous press operation for 2 seconds or more). If it is determined that the operation is a long press operation, the second channel having the priority assigned to the number button 13 that has been pressed and pressed is read from the setting memory 314a in accordance with the currently switched broadcast type. , Select that channel. Furthermore, while the numeric button 13 is being pressed long, a plurality of channels associated with the numeric button 13 are assigned in order of higher priority at every predetermined interval (for example, every second). Select them sequentially. When the long press operation of the numeric button 13 is finished, a control signal instructing channel selection of the channel selected when the long press operation is finished is output to the tuner 23, and broadcast data of the channel is received. Let
Although not shown in the figure, the CPU 311 causes the currently selected channel to be OSD-displayed on the display unit 29 while the numeric button 13 is being pressed for a long time, thereby notifying the user of the currently selected channel.

For example, in the state of switching to terrestrial digital broadcasting, the number button “8” 13 to which “081” is assigned as the first priority, “082” is assigned as the second priority, and “091” is assigned as the third priority. When the button is pressed for a long time, the CPU 311 first selects “082” having the second priority, and displays the OSD on the display unit 29 indicating that the channel “082” is selected. Then, at a predetermined interval (for example, every second), the channels assigned to the numeric button “8” 13 are sequentially selected in descending order of priority. That is, (“082”) → “091” (third channel of priority) → “081” (first channel of priority) →... Is selected at predetermined intervals. Further, for example, when the user ends the long press operation of the numeric button “8” 13 at the time of switching to “091”, the CPU 311 causes the tuner 23 to display “091” (the third priority channel). Is selected, and broadcast data of terrestrial digital broadcast “091” is received.
Also, for example, in the state of switching to CS digital broadcasting, belonging to the genre “sports”, “CS210” as the first priority, “CS216” as the second priority, “CS213” as the third priority, When the number button “3” 13 to which “CS211” is assigned as the fourth rank is operated for a long time, the CPU 311 first selects the second priority “CS216”, and “CS216” is selected. OSD is displayed on the display unit 29. Then, at a predetermined interval (for example, every second), the channels assigned to the numeric button “3” 13 are sequentially selected in descending order of priority. That is, (“CS216”) → “CS213” (third channel of priority) → “CS211” (fourth channel of priority) → “CS210” (first channel of priority) →... It will be selected at every interval. Further, when the user ends the long press operation of the numeric button “3” 13 at the time of switching to “CS211”, for example, the CPU 311 causes the tuner 23 to “CS211” (the fourth priority channel). Is selected, and broadcast data of CS digital broadcast “CS211” is received.
The CPU 311 functions as a second channel selection unit by executing the second channel selection program 315c.

Note that the channel switching based on the long press operation of the numeric button 13 is not limited to the case where the channel is switched from the second priority channel in the descending order of priority as described above. For example, a memory (not shown) is provided for storing the last channel viewed by pressing each numeric button 13, and when the numeric button 13 is pressed for a long time, viewing is performed by pressing the numeric button 13 based on the memory. The last channel may be switched in descending order of priority. Further, a memory is provided for storing the viewing history of the channels viewed by pressing each numeric button 13 in the order of the longest cumulative viewing time. When the numeric button 13 is operated for a long time, the numeric button is based on the memory. The channel with the longest viewing time may be switched in ascending order of viewing time from the channel viewed with the press of 13.
Further, the channel switching based on the long pressing operation of the number button 13 is not limited to the case of switching at a predetermined interval while the number button 13 is continuously pressed. For example, each time the numeric button 13 is pressed for several times, the channel may be sequentially switched to the channel associated with the numeric button 13.
In addition, the highest priority channel may not be included in the channel switched by the long press operation of the numeric button 13, and the highest priority channel may be switched only by a short press operation of the numeric button 13.

  Next, channel selection processing in the television receiver 100 of Embodiment 1 will be described with reference to the flowchart of FIG.

In step S <b> 1, the CPU 311 determines whether or not the numeric button 13 has been pressed in the remote control device 1. When the CPU 311 determines in step S1 that the numeric button 13 has been pressed (step S1; Yes), in step S2, the time during which the numeric button 13 is pressed is counted, and the pressing operation of the numeric button 13 is a short press operation ( For example, it is determined whether or not the pressing operation is less than 2 seconds.
If the CPU 311 determines in step S2 that the operation is a short press operation (step S2; Yes), in step S3, the CPU 311 reads the highest priority channel assigned to the number button 13 that has been operated by the short press operation from the setting memory 314a. Then, a control signal for instructing the tuning of the highest priority channel is output to the tuner 23, switching to reception of the broadcast data of the highest priority channel is performed, and this processing is terminated.

On the other hand, when the CPU 311 determines in step S2 that the pressing operation of the numeric button 13 is not a short pressing operation but a long pressing operation (for example, a continuous pressing operation for 2 seconds or more) (step S2; No), step S4 , The channel having the next priority (initial value = second priority) assigned to the numeric button 13 that has been pressed and pressed is read from the setting memory 314a, and the channel having the next priority is selected. The selected channel is OSD-displayed on the display unit 29. In this step S4, when the channel already selected is the channel with the lowest priority, the channel with the highest priority is set as the channel with the next priority.
Further, in step S5, the CPU 311 determines whether or not the long pressing operation of the number button 13 has been completed. If the CPU 311 determines in step S5 that the long pressing operation of the number button 13 has not ended (step S5; No), in step S6, a predetermined time (for example, 1 second) from the selection of the previous channel in step S4. It is determined whether or not elapses. If it is determined in step S6 that the predetermined time has not elapsed (step S5; No), the process returns to step S5 and the above processing is repeated. On the other hand, if it is determined that the predetermined time has elapsed (step S5; Yes). Returning to step S4, the above processing is repeated.

  On the other hand, when CPU 311 determines in step S5 that the long pressing operation of number button 13 has been completed (step S5; Yes), it instructs tuner 23 to select the channel selected at that time in step S7. The control signal to be output is output, switching to reception of broadcast data of the channel is performed, and this processing is terminated.

According to the television receiver 100 in the first embodiment described above, the remote control device 1 including a plurality of numeric buttons 13 is provided, and a plurality of channels assigned to each of the numeric buttons 13 by executing the channel / priority setting program 315a. Is set by the user, and a priority is set for each of the plurality of channels assigned to each of the numeric buttons 13, and based on the short press operation of the numeric buttons 13 by executing the first channel selection program 315b. Of the plurality of channels assigned to the numeric button 13, the channel with the highest priority set by the execution of the channel / priority setting program 315a is selected, and by the execution of the second channel selection program 315c, Based on the long press operation of the numeric button 13, while the numeric button 13 is being pressed A plurality of channels assigned to the numeric buttons 13 are sequentially selected, channel is selected to push the long operation has been selected at the time of completion. In addition, one genre is selected by the user by the channel / priority setting program 315a, and a list L2 of channels belonging to the selected one genre is displayed on the display unit 29, and the displayed on the display unit 29 The channel is selected and set by the remote controller 1 from among the channels.
That is, since the user can freely set a desired plurality of channels for each numeric button 13, when selecting a channel by pressing the numeric button 13, the efficiency is improved by switching to a channel that the user does not view. While preventing a fall, the usability of the remote control device 1 can be improved. When the numeric button 13 is operated for a short press, the channel having the highest priority is selected from among the plurality of channels set by the user, and when the numeric button 13 is pressed and operated for a long time, the channel set by the user is selected. Any channel is selected. Therefore, it is possible to provide the television receiver 100 that can efficiently switch to a desired channel by channel selection operation with excellent operability.

  Also, since the priority is set for each of the plurality of channels assigned to each of the numeric buttons 13 by the execution of the channel / priority setting program 315a, for example, the user himself is highly likely to desire channel selection. If priority is set in the order of channels, it becomes easier to select a desired channel assigned to the numeric buttons 13. In particular, if the channel with the highest possibility of channel selection is set to the highest priority, this channel can be selected very easily by a short press operation of the numeric buttons 13.

  Further, when the second channel selection program 315c is executed, a plurality of channels assigned to the numeric button 13 are sequentially selected while the numeric button 13 is being pressed and held, and the long press operation is completed. Since the channel selected in (1) is selected, each channel to which the numeric button (13) is assigned can be selected very easily by simply pressing and holding the numeric button (13).

Also, by executing the channel / priority setting program 315a, one genre is selected by the user, and a list L2 of channels belonging to the selected one genre is displayed on the display unit 29 and displayed on the display unit 29. A channel is selected and set by the user from the remote controller 1 using the remote controller 1.
Therefore, the user can set a plurality of channels belonging to one genre to each numeric button 13, and can realize a channel selection operation that is more convenient for the user. In particular, this is effective when channels that specially distribute programs of a specific genre are collectively assigned to one numeric button 13. That is, for example, when a user wants to watch a program of the genre “sports”, if the user operates the numeric buttons 13 to which a plurality of channels belonging to the genre “sports” are assigned, the user belongs to the genre “sports” that he / she wants to watch. It is possible to efficiently switch to the desired channel. In addition, when one genre is selected in the channel setting operation, channels belonging to that genre are displayed on the display unit 29, and a desired channel can be selected from among them. The operation of assigning channels to the numeric buttons 13 can be easily performed.
