<1. First Embodiment>
<1-1. Configuration>
FIG. 1 is a block diagram showing an outline of the configuration of the display system 100 of the present embodiment. The display system 100 is an in-vehicle device mounted on a vehicle such as an automobile. The display system 100 includes a display 3 that is a display device, and has a function as a video processing device that displays video on the display 3. The display system 100 has, as main functions, a disc playback function for playing back content on a recording medium and a broadcast playback function for playing back digital broadcast content.

  As shown in FIG. 1, a display system 100 includes a main body unit 10 that controls the entire system, a display 3 that displays various types of information, a speaker 4 that outputs various types of audio, and an operation unit 5 that is operated by a user. I have.

  The operation unit 5 includes a main controller 50 and a source switching button 59. The main controller 50 is mainly operated by a user when various instructions are given to the display system 100. On the other hand, the source switching button 59 is a button for switching a video source to be displayed on the display 3 between a recording medium and digital broadcasting. That is, by operating the source switching button 59, either the disc playback function or the broadcast playback function can be validated.

  The display 3, the speaker 4, and the operation unit 5 are electrically connected to the main body unit 10 via a cable. For this reason, the display 3 and the speaker 4 operate under the control of the main body unit 10, and the user's operation content on the operation unit 5 is input to the main body unit 10 as a signal.

  The main body 10 is a device that controls the entire display system 100 and is disposed at a predetermined position of the vehicle. The main body unit 10 includes a control unit 1 having various control functions, a disk reading unit 21 that reads a recording medium, and a broadcast receiving unit 22 that receives a broadcast signal.

  The disc reading unit 21 reads the recorded content of a recording medium such as a DVD and a BD (Blu-ray Disc) and decodes the recorded content to obtain a video signal and an audio signal. The broadcast receiving unit 22 includes an antenna that receives broadcast signals of digital broadcasts including digital television broadcasts (DTV), and decodes the received broadcast signals to acquire video signals and audio signals.

  The control unit 1 includes a computer including a CPU, a RAM, a ROM, and the like, and various control functions are realized by the CPU performing arithmetic processing according to a program as firmware stored in advance in the ROM or the like. The display control unit 11, the instruction receiving unit 12, and the instruction execution unit 13 illustrated in the drawing show some of the functions of the control unit 1 realized in this way.

  The display control unit 11 performs control related to display on the display 3 and output from the speaker 4. When reproducing the content of the recording medium, the display control unit 11 outputs the video signal and the audio signal acquired by the disc reading unit 21 to the display 3 and the speaker 4, respectively. Thereby, the video of the recording medium is displayed on the display 3, and sound is output from the speaker 4. When playing back digital broadcast content, the display control unit 11 outputs the video signal and audio signal acquired by the broadcast receiving unit 22 to the display 3 and the speaker 4, respectively. As a result, the digital broadcast video is displayed on the display 3, and sound is output from the speaker 4.

  The instruction receiving unit 12 receives a user instruction to the display system 100 based on an operation on the operation unit 5. The instruction execution unit 13 controls the entire display system 100 and executes the user instruction received by the instruction receiving unit 12.

  An instruction corresponding to the current situation of the display system 100 is assigned to each operation that can be performed on the operation unit 5. When a user operation is performed on the operation unit 5, a signal indicating the operation content is input to the instruction receiving unit 12. In response to this signal, the instruction receiving unit 12 receives an instruction assigned to the operation, and the instruction executing unit 13 executes the received instruction.

  In the display system 100, a GUI (graphical user interface) is adopted as a user interface. When receiving an instruction from the user in the GUI, a list of a plurality of items as selection candidates is displayed on the display 3. An instruction for the display system 100 is assigned to each of the plurality of items included in the list. While confirming the screen on which this list is displayed, the user operates the operation unit 5 to move the cursor (focus) to select a desired item. As a result, the instruction receiving unit 12 receives an instruction assigned to the selected item, and the instruction executing unit 13 executes the received instruction.

  The display 3, the speaker 4, and the operation unit 5 are arranged at positions suitable for each in the vehicle interior independently of the main body unit 10. FIG. 2 is a diagram illustrating an example of the arrangement of the display 3, the speaker 4, and the operation unit 5 in the vehicle interior.

  As shown in the figure, the display 3 is disposed at the center of the left and right of the instrument panel 91 of the vehicle so that the amount of movement of the line of sight of the driver to be viewed is reduced. The speaker 4 is disposed close to the display 3.

  Further, the operation unit 5 is arranged apart from the display 3 and the speaker 4 so that the user can easily operate. Specifically, the operation unit 5 is disposed in the vicinity of the shift lever 94 in the center console 93 of the vehicle. The main controller 50 is disposed behind the shift lever 94, and a source switching button 59 is provided around the main controller 50. Since the vehicle according to the present embodiment is a right-hand drive vehicle, the driver operates the shift lever 94 with the left hand as needed while operating the steering wheel 92 during driving. Since the operation unit 5 is disposed close to the shift lever 94, the driver can operate the operation unit 5 with the left hand (one hand) while in the driving position.

  The main controller 50 of the operation unit 5 includes a single operation member that can receive all of rotation operation, pressing operation (push operation), and direction operation (slide operation) from the user. The user can perform all of the rotation operation, the pressing operation, and the direction operation on the main controller 50 with only one hand.

  FIG. 3 is a perspective view showing an appearance of the main controller 50. As shown in the figure, the main controller 50 has a substantially cylindrical shape, and the size of the main controller 50 is such that the user can cover the whole with one hand.

  The main controller 50 can accept a rotation operation that rotates in the direction indicated by the arrow AR1 in the drawing. When this rotation operation is performed, a signal indicating that the rotation operation has been performed and the rotation direction (left direction and right direction) is input to the control unit 1. A rotary encoder can be adopted as a device that outputs such a signal.

  Further, the main controller 50 can accept a pressing operation for pushing in the direction indicated by the arrow AR2 in the drawing. When this pressing operation is performed, a signal indicating that the pressing operation has been performed is input to the control unit 1. The function of outputting such a signal can be realized by adopting, for example, a press switch that is pressed by a part of the main controller 50 moved by a pressing operation.

  Furthermore, the main controller 50 can accept a direction operation that slides in four directions indicated by an arrow AR3 in the drawing. When this direction operation is performed, a signal indicating that the direction operation has been performed and the direction (slid direction) indicated by the direction operation is input to the control unit 1. The function of outputting such a signal can be realized by employing, for example, a plurality of pressing switches that are pressed by a part of the main controller 50 moved by a direction operation. The push switches are respectively arranged in four directions that can be indicated by a direction operation.

  In the display system 100, an image to be displayed can be changed by rotating the main controller 50. For example, if a rotation operation is performed during the reproduction of content on a recording medium, a chapter to be displayed can be changed. Further, if a rotation operation is performed during the reproduction of digital broadcast content, the channel to be displayed can be changed. Hereinafter, the details of the video change by the rotation operation will be described.

<1-2. Rotation operation in disc playback function>
First, a case where content on a recording medium is played back by the disc playback function will be described.

  FIG. 4 is a diagram showing a display example of the screen of the display 3 when reproducing the content of the recording medium. As shown in the figure, the screen of the display 3 is divided into two areas, a first area A1 in which character strings are mainly displayed and a second area A2 in which video is mainly displayed.

  The first area A1 is an area narrower than the second area A2 arranged on the left side of the screen, and a character string related to the video displayed in the second area A2 is displayed. For example, a title M1 of the recording medium, a chapter number M2 indicating a chapter that is currently displayed, and the like are displayed in the first area A1. On the other hand, the second area A2 is arranged on the right side of the screen and displays the video (usually a moving image) of the chapter to be displayed.

  When a user performs a rotation operation with the main controller 50 during display of a normal image on a recording medium as illustrated in FIG. 4, a chapter to be displayed is changed. FIG. 5 is a diagram illustrating an example of screen transition of the display 3 when this rotation operation is performed.

  When a normal operation is being performed on the recording medium (state ST10) and a rotation operation is performed, a list M3 indicating a plurality of items corresponding to a plurality of chapters of the recording medium is displayed in the first area A1 (state). ST11). This rotation operation may be either a right rotation operation (hereinafter referred to as “right rotation operation”) or a left rotation operation (hereinafter referred to as “left rotation operation”).

  In the list M3, a plurality of items indicating chapters that are selection candidates (more precisely, chapter numbers) are arranged in the vertical direction. On the screen of the display 3, only items corresponding to some of the selectable chapters (up to five) are included in the list M3 and displayed due to display size restrictions. Among the displayed items, a cursor C is displayed on an item indicating a chapter that is currently displayed. In this example, the number of the chapter is shown in the item of the list M3, but it is also possible to show a still image or a moving image corresponding to the chapter. In this case, the user selects a chapter based on the still image or moving image.

  In a state where the list M3 is displayed, the user can move the cursor C to another item by performing a rotation operation with the main controller 50. Thereby, the user can select a chapter to be displayed from chapters indicated by a plurality of items included in the list M3. A plurality of items included in the list M3 are arranged along an arc. With such an arrangement of items, the user can intuitively understand that the movement of the cursor C to another item can be performed by a rotation operation.

  When the rotation operation is performed by the main controller 50, the cursor C is maintained at the upper and lower centers of the central area, while a plurality of items included in the list M3 are scrolled. As a result, the cursor C moves relative to the plurality of items.

  Specifically, by performing a clockwise rotation operation with the main controller 50, each item scrolls up (scrolls upward), so that the cursor C can be moved to the next lower item. For example, if the right rotation operation is performed in the state ST11, as shown in the state ST12, the items indicating the chapters displayed in the state ST11 are moved upward one by one. In the state ST11, the cursor C is on the item "1". On the other hand, in the state ST12, the cursor C is on the item "2" immediately below the item "1". Conversely, when the main controller 50 performs a left rotation operation, each item scrolls down (scrolls downward), so that the cursor C can be moved up one item.

  When the cursor C is moved in this way, the chapter indicated by the item with the cursor C after the movement is selected as a new display target. Then, the chapter video that is the display target is displayed in the second area A2. In this way, the video and the list M3 are displayed in the same screen of the display 3, and the video of the selected chapter is promptly displayed in the second area A2 after the chapter is selected. For this reason, the user can easily select a chapter including a desired video.

  When the list M3 is displayed and the state where there is no rotation operation continues for a predetermined time (for example, 2 seconds), the display of the list M3 is canceled (state ST13). In this state, in order to display the list M3 again, the rotation operation may be performed again.

  Thus, the user can display the list M3 by a rotation operation, and can select a chapter to be displayed from the displayed list M3 by a further rotation operation. Such processing is realized by the control of the instruction receiving unit 12 and the instruction execution unit 13. That is, the instruction receiving unit 12 receives a rotation operation as an instruction to display a list M3 indicating a plurality of chapters on the display 3, and also receives a rotation operation as an instruction to select a chapter to be displayed from the list M3. become. Both of these instructions are executed by the instruction execution unit 13. Thereby, the user can change the video to be displayed without performing any operation other than the rotation operation.

  FIG. 6 is a diagram illustrating a processing flow of the display system 100 when a rotation operation is performed during the display of video on a recording medium.

  When the main controller 50 is rotated while the video on the recording medium is being displayed, the instruction receiving unit 12 receives this rotating operation as an instruction to display the list M3 on the display 3. Then, the instruction execution unit 13 executes the instruction and displays the list M3 on the display 3 (step S11).

  Next, it is determined whether or not there is a rotation operation in the display state of the list M3 (step S12). If the state where there is no rotation operation continues for a predetermined time (for example, 2 seconds) (No in step S12), the display of the list M3 is canceled and the process ends (step S18).

  On the other hand, when there is a rotation operation in the display state of the list M3 (Yes in step S12), the instruction receiving unit 12 receives the rotation operation as an instruction to select a chapter to be displayed. Then, the instruction execution unit 13 executes the instruction.

  Specifically, first, the rotation direction of the rotation operation is determined (step S13). In the case of the left rotation operation, each item in the list M3 is scrolled down and the cursor C is moved to the upper item (step S14). On the other hand, in the case of the right rotation operation, each item in the list M3 is scrolled up and the cursor C is moved to the lower item (step S15).

  When the cursor C is moved, the chapter indicated by the item with the cursor C is selected as a display target. Then, the video of the selected chapter is displayed in the second area A2 (step S16).

  If a further rotation operation is performed (Yes in step S17), the process returns to step S13, and the cursor C is moved according to the rotation direction of the rotation operation. As a result, the user can move the cursor C to a desired item and select a desired chapter as a chapter to be displayed.

  When the state where there is no rotation operation continues for a predetermined time (for example, 2 seconds) (No in step S17), the display of the list M3 is canceled and the process ends (step S18).

  As described above, in the display system 100, the instruction accepting unit 12 displays an instruction for causing the display 3 to display the list M3 indicating a plurality of chapters of the recording medium, and the rotation operation performed during the display of the video of the recording medium. Then, it is accepted as an instruction to select a chapter to be displayed on the display 3 from the list M3. For this reason, the user can display a list of a plurality of chapters of the recording medium on the display 3 only by performing a rotation operation, and can select a chapter to be displayed from the list M3. As a result, a complicated operation is not required, and an image to be displayed can be changed by a simple operation such as a rotation operation.

<1-3. Rotation operation in broadcast playback function>
Next, a case where digital broadcast content is reproduced by the broadcast reproduction function will be described.

  FIG. 7 is a diagram showing a display example of the screen of the display 3 in the case of reproducing digital broadcast content. Also in this case, the screen of the display 3 is divided into two areas, a first area A1 in which character strings are mainly displayed and a second area A2 in which video is mainly displayed.

  In the first area A1, the title M4 of the program that is currently displayed, the channel number M5 that indicates the channel that is currently displayed, and the like are displayed. In the second area A2, a video (usually a moving image) of a channel to be displayed is displayed.

  When a user performs a rotation operation with the main controller 50 during display of a normal digital broadcast image as illustrated in FIG. 7, the channel to be displayed is changed. FIG. 8 is a diagram illustrating an example of transition of the screen of the display 3 when this rotation operation is performed.

  When a normal operation of digital broadcasting is being displayed (state ST20), if a rotation operation is performed, a list M6 indicating a plurality of items corresponding to a plurality of channels of digital broadcasting is displayed in the first area A1 (state) ST21). This rotation operation may be either a right rotation operation or a left rotation operation.

  The list M6 includes a plurality of items indicating channels (more precisely, channel numbers) as selection candidates. In a state where the list M6 is displayed, the user can move the cursor C to another item by performing a rotation operation with the main controller 50 (state ST22). Accordingly, the user can select a channel to be displayed from channels indicated by a plurality of items included in the list M6. The relationship between the rotation operation and the movement of the cursor C is the same as when a chapter of the recording medium is selected.

  When the cursor C is moved, the channel indicated by the item with the moved cursor C is selected as a new display target. Then, the video of the display target channel is displayed in the second area A2. In this way, the video and the list M6 are displayed in the same screen of the display 3, and the video of the selected channel is quickly displayed in the second area A2 after the channel is selected. For this reason, the user can easily select a channel that broadcasts a desired program.

  When the list M6 is displayed and the state where there is no rotation operation continues for a predetermined time (for example, 2 seconds), the display of the list M6 is canceled (state ST23). In this state, in order to display the list M6 again, the rotation operation may be performed again.

  Thus, the user can display the list M6 by a rotation operation, and can select a channel to be displayed from the displayed list M6 by a further rotation operation. Such processing is realized by the control of the instruction receiving unit 12 and the instruction execution unit 13. That is, the instruction receiving unit 12 receives a rotation operation as an instruction to display a list M6 indicating a plurality of channels on the display 3, and also receives a rotation operation as an instruction to select a channel to be displayed from the list M6. become. Both of these instructions are executed by the instruction execution unit 13. Thereby, the user can change the video to be displayed without performing any operation other than the rotation operation.

  FIG. 9 is a diagram illustrating a processing flow of the display system 100 when a rotation operation is performed during display of a digital broadcast video.

  When the main controller 50 is rotated during display of the digital broadcast video, the instruction receiving unit 12 receives the rotation operation as an instruction to display the list M6 on the display 3. Then, the instruction execution unit 13 executes the instruction and displays the list M6 on the display 3 (step S21).

  Next, it is determined whether or not there is a rotation operation in the display state of the list M6 (step S22). When the state where there is no rotation operation continues for a predetermined time (for example, 2 seconds) (No in step S22), the display of the list M6 is canceled and the process ends (step S28).

  On the other hand, when there is a rotation operation in the display state of the list M6 (Yes in step S22), the instruction receiving unit 12 receives the rotation operation as an instruction for selecting a channel to be displayed. Then, the instruction execution unit 13 executes the instruction.

  Specifically, first, the rotation direction of the rotation operation is determined (step S23). In the case of the left rotation operation, each item in the list M6 is scrolled down and the cursor C is moved to the upper item (step S24). On the other hand, in the case of the right rotation operation, each item in the list M6 is scrolled up and the cursor C is moved to the lower item (step S25).

  When the cursor C is moved, the channel indicated by the item with the cursor C is selected as a display target. Then, the video of the selected channel is displayed in the second area A2 (step S26).

  If a further rotation operation is performed (Yes in step S27), the process returns to step S23, and the cursor C is moved according to the rotation direction of the rotation operation. Accordingly, the user can move the cursor C to a desired item and select a desired channel as a channel to be displayed.

  When the state where there is no rotation operation continues for a predetermined time (for example, 2 seconds) (No in step S27), the display of the list M6 is canceled and the process ends (step S28).

  As described above, in the display system 100, the instruction accepting unit 12 displays an instruction for causing the display 3 to display the list M6 indicating a plurality of channels of the digital broadcast, and the rotation operation performed during the display of the digital broadcast video. , And an instruction to select a channel to be displayed on the display 3 from the list M6. For this reason, the user can display a list of a plurality of channels of digital broadcasting on the display 3 only by performing a rotation operation, and can select a channel to be displayed from the list M6. As a result, a complicated operation is not required, and an image to be displayed can be changed by a simple operation such as a rotation operation.

<2. Second Embodiment>
Next, a second embodiment will be described. Since the basic configuration and operation of the display system 100 of the second embodiment are the same as those of the first embodiment, the following description will focus on the differences from the first embodiment.

  In the first embodiment, when a rotation operation is performed during display of a digital broadcast video, a list M6 indicating a channel is displayed. On the other hand, in the second embodiment, as shown in FIG. 10, when a rotation operation is performed during display of a digital broadcast video (state ST30), an electronic program guide (EPG) is also called. The program guide T is displayed on the entire screen (state ST31). This rotation operation may be either a right rotation operation or a left rotation operation.

  The electronic program guide T shows a plurality of programs scheduled to be broadcast by digital broadcasting, classified by channel (broadcast station) and broadcast time. Information of the electronic program guide T is acquired by receiving a broadcast signal of a predetermined channel and decoding the broadcast signal. The electronic program guide T includes a plurality of items (program columns) corresponding to each program arranged vertically and horizontally in a grid pattern. The program channel is indicated by the horizontal direction of the electronic program guide T, and the broadcast time of the program is indicated by the vertical direction of the electronic program guide T. The number of channels included in the electronic program guide T is the number of broadcast stations that can be received in the current region (the region set in the initial setting). In the electronic program guide T, a cursor C is displayed in the program item to be displayed.

  In a state where the electronic program guide T is displayed, the user can move the cursor C to another item by performing a rotation operation with the main controller 50. Thus, the user can select a program to be displayed from programs indicated by a plurality of items included in the electronic program guide T.

  Specifically, as shown in FIG. 11, the cursor can be moved to the right by performing a right rotation operation on the main controller 50 (state ST32). Thereby, the user can select the channel of the program to be displayed from the programs indicated by the electronic program guide T. On the other hand, by performing a left rotation operation with the main controller 50, the cursor can be moved downward (state ST33). Thereby, the user can select the broadcast time of the program to be displayed from the programs indicated by the electronic program guide T.

  Only items corresponding to a part of selectable programs included in the electronic program guide T are displayed on the screen of the display 3 due to display size restrictions. When the cursor C is moved to an item of a program not displayed on the screen, the item being displayed is scrolled and the item of the program is displayed on the screen.

  Further, when the cursor C is moved to the position of the rightmost channel of the electronic program guide T, the cursor C is moved to the position of the leftmost channel of the electronic program guide T by further rotating the main controller 50 to the right. Can be made. Further, when the cursor C is moved to the position of the broadcast time at the lower end of the electronic program guide T, the main controller 50 further performs a left rotation operation, so that the cursor C is moved to the broadcast time at the upper end of the electronic program guide T (for example, , The current time) position. The broadcast time included in the electronic program guide T is preferably limited to a predetermined time after the current time (for example, one day later) or a predetermined time (for example, 24:00) on that day. In addition, it is preferable that the user can set a restriction on the broadcast time included in the electronic program guide T.

  In this way, the user can display the electronic program guide T by a rotating operation. Then, the channel of the program to be displayed can be selected from the displayed electronic program guide T by performing a right rotation operation, and the broadcast time of the program to be displayed is selected by performing a left rotation operation. be able to. Such processing is executed under the control of the instruction receiving unit 12 and the instruction execution unit 13. That is, the instruction receiving unit 12 receives the rotation operation as an instruction to display the electronic program guide T on the display 3. At the same time, the instruction accepting unit 12 accepts a right rotation operation as an instruction to select a channel of a program to be displayed, and accepts a left rotation operation as an instruction to select a broadcast time of a program to be displayed. . All of these instructions are executed by the instruction execution unit 13. Thereby, the user can change the program to be displayed without performing an operation other than the rotation operation.

  FIG. 12 is a diagram illustrating a processing flow of the display system 100 when a rotation operation is performed during display of a digital broadcast video.

  When a rotation operation is performed on the main controller 50 during the display of the digital broadcast video, the instruction receiving unit 12 receives this rotation operation as an instruction to display the electronic program guide T on the display 3. Then, the instruction execution unit 13 executes the instruction and displays the electronic program guide T on the entire screen of the display 3 (step S31). At this time, the cursor C is displayed in the program item displayed before the electronic program guide T is displayed.

  Next, it is determined whether or not there is a rotation operation in the display state of the electronic program guide T (step S32). If the state where there is no rotation operation continues for a predetermined time (for example, 2 seconds) (No in step S32), the display of the electronic program guide T is canceled and the process ends (step S41).

  On the other hand, if there is a rotation operation in the display state of the electronic program guide T (Yes in step S32), the instruction receiving unit 12 receives an instruction to select a channel of a program to be displayed in the case of a right rotation operation. In the case of the left rotation operation, an instruction to select the broadcast time of the program to be displayed is accepted. Then, the instruction execution unit 13 executes the instruction.

  Specifically, first, the rotation direction of the rotation operation is determined (step S33). In the case of the left rotation operation, the cursor C is moved to the lower item in the electronic program guide T (step S34). On the other hand, in the case of the right rotation operation, the cursor C is moved to the right item in the electronic program guide T (step S35). When the cursor C is moved, the program indicated by the item with the cursor C is selected as a display target.

  If a further rotation operation is performed (Yes in step S36), the process returns to step S33, and the cursor C is moved according to the rotation direction of the rotation operation. Accordingly, the user can move the cursor C to a desired item and select a desired program as a program to be displayed.

  When the state where there is no rotation operation continues for a predetermined time (for example, 2 seconds) (No in step S36), the display of the electronic program guide T is canceled (step S37). Subsequently, it is determined whether or not the program selected as the display target is a program being broadcast at the current time (step S38). If the selected program is a program being broadcast at the current time, the video of the program is displayed in the second area A2 (step S39). On the other hand, if the selected program is not being broadcast at the current time, a reservation for displaying the program is made (step S40). When the program is reserved in this way, immediately after the reservation, the video of the program displayed before the display of the electronic program guide T is displayed in the second area A2. Then, when the start time of the reserved program is reached, the video of the reserved program is displayed in the second area A2.

  As described above, in the display system 100, the instruction receiving unit 12 receives a rotation operation performed during display of a digital broadcast video as an instruction to display the electronic program guide T on the display 3. At the same time, the instruction receiving unit 12 receives a right rotation operation as an instruction to select a channel of a program to be displayed on the display 3 from the electronic program guide T, and displays a left rotation operation from the electronic program guide T. 3 is received as an instruction to select the broadcast time of the program to be displayed. For this reason, the user can display the electronic program guide T on the display 3 only by performing a rotation operation, and can select a program to be displayed from the electronic program guide T. As a result, a complicated operation is not required, and a program to be displayed can be changed by a simple operation such as a rotation operation.

<3. Modification>
Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications are possible. Below, such a modification is demonstrated. All forms including those described in the above embodiment and those described below can be combined as appropriate.

  In the above embodiment, the recording medium is described as being a disk medium such as a DVD and a BD (Blu-ray Disc). However, the recording medium is a recording medium employing a flash memory (semiconductor memory) or a hard disk. Also good.

  In the first embodiment, the first rotation operation is accepted as an instruction to display a list, and the next rotation operation is accepted as an instruction to select a chapter or channel. On the other hand, one rotation operation may be accepted as both an instruction to display a list and an instruction to select a chapter or channel. In this case, the user can change the chapter or channel while displaying the list by performing the rotation operation only once. Also in the second embodiment, one right rotation operation is accepted as both an instruction to display the electronic program guide T and an instruction to select a channel, and one left rotation operation is an instruction to display the electronic program guide T. And an instruction to select a time zone may be accepted.

  Further, in the first embodiment, it has been described that the list M6 indicating the channel number is displayed when the rotation operation is performed during the display of the normal video of digital broadcasting. On the other hand, an electronic program guide showing a program being broadcast at the current time may be displayed, and a channel to be displayed may be selected while viewing the electronic program guide.

  In addition, the instruction assigned to the right rotation operation and the instruction assigned to the left rotation operation described in the above embodiment may be opposite to each other.

  In the above embodiment, a display system mounted on a vehicle such as an automobile has been described as an example. However, any display system having a function of a video processing device for displaying video on a display device may be used. Even if it is a thing, the technique demonstrated above can be applied suitably. A display system having the function of such a video processing device is typically a vehicle-mounted device such as a car navigation device or a car audio device, or a portable device such as a mobile phone or a portable game machine.

  Further, in the above-described embodiment, it has been described that various functions are realized in software by the arithmetic processing of the CPU according to the program. However, some of these functions are realized by an electrical hardware circuit. Also good.
