DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0015]
First, the configuration of the entire system of the apparatus of this example will be described with reference to FIG. 1 and FIG. In this example, the information processing system is installed in a vehicle (here, an automobile). Specifically, as shown in FIG. 2, a monitor device 14 made of a relatively small liquid crystal image display panel is mounted on a dashboard in the automobile 1, and this monitor device 14 is a console under the dashboard. The controller 10 installed in the unit or the like is connected, and various information obtained by the controller 10 is displayed on the display unit of the monitor device 14. Various information processing devices are connected to the controller 10 via a predetermined bus line.
[0016]
The devices connected to the controller 10 are here a navigation device 20, a DVD device 40, a television tuner 50, a CD changer device 60, a monitor device 70, an amplifier device 80, a video camera 90, and the like. The DVD device 40 is a device that reproduces an optical disc called a DVD (Digital Video Disc or Digital Versatile Disc). The CD changer device 60 is loaded with a plurality of optical discs called CDs (Compact Discs). This is a device for reproducing a desired disc.
[0017]
These devices are connected in a predetermined order by a bus line, and are installed in a vacant space (console section, lower part of a seat, inside a trunk, etc.) in the vehicle. However, the monitor device 70 is installed here as a monitor for the rear seat, and is installed at a position that can be seen from the rear seat side. In addition, the video camera 90 is a device configured for portable use, and is installed at an arbitrary position in the vehicle (such as on a seat).
[0018]
Next, a specific system configuration will be described with reference to FIG. 1. The monitor device 14 includes a video display unit 14 a configured by a liquid crystal panel or the like, and displays a predetermined video (image) under the control of the controller 10. To do. The monitor device 14 includes a remote control signal receiver 14b, receives (receives) an infrared signal transmitted from the remote control device 17 and the like, and transmits control information indicated by the received signal to the controller 10. .
[0019]
The remote control device 17 is configured to transmit a signal capable of controlling each device connected to the system of this example. For example, a device code of an infrared signal transmitted based on a key operation can be set to data corresponding to the device to be operated. That is, FIG. 3 shows an example of an infrared signal transmitted from the remote control device 17. FIG. 3 shows a pulse signal transmitted as an infrared signal. The high-level period is a period during which the infrared signal is emitted. The low level period is a period during which no infrared signal is emitted. As shown in FIG. 3, when one unit of infrared signal is transmitted, a guide pulse having a predetermined length is first emitted, and then a data code indicating information to be controlled is set to a predetermined number of bits (here, 7 bits). ) And a category code indicating the type of device to be controlled last is transmitted in a predetermined number of bits (here, 8 bits). Here, the category code is changed according to the device to be operated (navigation device 20, DVD device 40, television tuner 50, etc.).
[0020]
The controller 10 discriminates the category code of the remote control signal received by the remote control signal receiver 14b, determines which device is the information to be controlled, and transfers the control information to the device connected by the bus line. Process. Alternatively, a remote control device may be prepared for each device, and an infrared signal from the remote control device for each device may be received by the receiving unit 14b.
[0021]
As a bus line for connecting each device to the controller 10, here, a bus line according to a standard called IEEE 1394 recognized by the Institute of Electrical and Electronics Engineers (IEEE) is used. The bus line according to the IEEE 1394 standard is applied to a bus line that is connected using a terminal called a DV terminal provided in a consumer digital video device, for example. For example, as shown in FIG. 4, a connection cable 3 in which a power supply line 3a, a data line 3b, and a strobe line 3c are bundled and shielded is used as a cable used for the bus line connection. Further, as the port section 2 on the device side to which the connection cable 3 is connected, a power supply circuit 2a that performs output or input processing of a DC low-voltage power supply to the power supply line 3a, and input / output processing of data transmitted through the data line 3b And a strobe processing circuit 2c for performing input / output processing of data (strobe) transmitted through the strobe line 3c. An interface unit provided in each device described later includes one or a plurality of the port units 2.
[0022]
The strobe transmitted through the strobe line 3c is a signal that supplements the data transmitted through the data line 3b, and the data clock is generated by taking the exclusive OR of the data and the strobe. For example, as shown in FIG. 5, when the data transmitted through the data line 3b is in the state shown in FIG. 5A, the strobe becomes a signal that is inverted at a timing when the data does not change, as shown in FIG. 5B. By taking the exclusive OR of both signals, the clock shown in FIG. 5C is generated on the receiving side.
[0023]
When the bus line is connected to the port portion of the IEEE 1394 standard, an address is automatically given to each connected device under the control of the master device, and the transfer is performed using the address. In this configuration, the transmission source and reception destination of information to be specified are specified, and the master device stores the address of the connected device. At this time, in this example, information on the type and category of the device is also stored by the master device. That is, the type of the connected device is determined, the category (classification) to which the determined device type belongs is determined, and the category is also stored. In the case of this example, the controller 10 performs this process.
[0024]
In addition, there are two types of transmission methods using the IEEE 1394 standard bus line: an asynchronous transfer mode, an asynchronous transfer mode, and a real-time data transfer mode, an isochronous transfer mode. Depending on the type of information to be transmitted, Can be used properly. Specifically, information such as control information of each device is transferred in units of packets in the asynchronous transfer mode. FIG. 6 shows a packet transferred in this asynchronous transfer mode, and an arbitration process for acquiring a bus line is executed from a port unit that desires data transfer. When the bus line transfer right is acquired by this arbitration process, the data packet is transmitted next. This data packet is composed of a header part and a data part. The header part includes information such as a partner address, a self address, and a transfer data size, and the data part includes data to be actually transferred. A CRC code for error correction is added to each data of the header part and the data part.
[0025]
On the side that has received data in the asynchronous transfer mode, the reception result for the transferred data is returned to the transmission source as an acknowledgment code that is a return code for reception confirmation. The above processing is repeated as long as there is data to be transferred.
[0026]
For large-capacity information that requires real-time transfer such as video information and audio information, data transfer is performed in an isochronous transfer mode. FIG. 7 shows a packet transferred in the isochronous transfer mode, and an arbitration process for acquiring the bus line of the first channel (first channel) is executed from the port unit for which data transfer is desired. To do. When the transfer right of the bus line is acquired by this arbitration process, a data packet on the first channel is transmitted next, and arbitrary information such as video information is transferred by this data packet. When the first channel packet ends, a predetermined gap is opened, and then the second channel arbitration and data packet transfer are performed. Thereafter, transmission of data necessary for the data packet is completed. An arbitrary number of channels are repeatedly transmitted. In this case, the isochronous transfer mode is a transfer mode in which transfer is executed with priority over the asynchronous transfer mode and the transfer band is guaranteed. In the isochronous transfer mode, the return code for confirmation of reception is not transmitted.
[0027]
By connecting the devices by the bus line configured and operated in this way, various information can be transferred between arbitrary devices among the plurality of connected devices.
[0028]

It should be noted that the connection order by bus line is an example, and any connection may be used as long as it is permitted by the bus line standard (IEEE 1394 standard) of this example. Also, devices other than those shown in FIG. 1 may be connected.
[0040]
Next, processing when controlling each device connected by the bus line under the control of the controller 10 of this example will be described with reference to the drawings after FIG.
[0041]
In this example, the controller 10 is configured to be able to determine a device connected by a bus line and display the connection state on the monitor device 14 (or another monitor device).
[0042]
For example, FIG. 8 shows an example in which the connection state is displayed on the monitor device 14 (this example is different from the connection configuration of FIG. 1). In this example, the blocks displayed on the screen are the first monitor 101, FM / MD controller 102, front speakers 103 to 106, electronic still camera 107, video camera 108, second monitor 109, amplifier device 110, rear speaker. 111, 112, digital audio processing device 113, digital broadcast tuner 114, television broadcast tuner 115, U navigation device 116, DVD device 117, MD storage device 118, and CD changer device 119.

In other words, equipment installed in front of the car (in the vicinity of the dashboard, etc.) is displayed on the left side, equipment installed in the rear of the car (in the trunk, etc.) is displayed on the right side, and vehicles such as speakers are displayed. The devices installed in the room are displayed in the meantime. As described above, in the case of this example, the connection order on the bus line may be any order, and the connection display in this example shown in FIG. 8 does not display the actual connection order. It is displayed in a state that is easy to understand for the user reflecting the state of arrangement in the car.
[0044]
By viewing this connection display, the user can easily determine the devices that can be used, and can instruct various processes using the connected devices. Here, for example, when a selection process of a disc to be reproduced by a CD changer device is described, a selection menu is displayed on the screen of the monitor device 14 using a remote control device or the like. FIG. 9 shows an example of the selection menu screen. In the leftmost main menu, all categories of the prepared devices are displayed, and the display color of the display portion of the selected category (classification) is changed. Here, the audio / video category is selected.
[0045]
When this category is selected, as shown in FIG. 9, a list of devices belonging to the audio / video category among the devices connected by the bus line is displayed on the right side of the main menu, and selected from the list. Change the display color of the display part of the connected device. Here, the CD changer is selected.

When this device is selected, an operation list of this device is displayed on the right side of the device display. In the case of a CD changer, a list of disc numbers is displayed, and the display color of the display portion of the selected disc number is changed. Here, disc number 2 is selected.
[0047]
When this disc number is selected, a list of track numbers recorded on the disc of this number is displayed on the right side of the disc number display. In the disc number display, the display color of the display portion of the selected track number is changed. With the selection made so far, the playback key of the remote control device is pressed and a playback instruction is sent to the controller 10, so that the controller 10 sends the disk number and track to the CD changer device via the bus line. The number playback command arrives and playback of the corresponding track number is started.
[0048]
In the case of a bus line according to the IEEE 1394 standard, transmission of the reproduction command and the like is executed from the request side (controller) to the response side (CD changer device) in the state shown in FIG. Processing is also performed.
[0049]
In this example, as shown in FIG. 8, not only the whole display of devices connected via the bus line but also the display for each category (classification) can be made. That is, as a connection display on the monitor device 14 performed based on the control of the controller 10, when a category is designated by an operation of a remote control device or the like, a connection display of devices in the category is performed. FIG. 11 is a diagram showing a display example when a navigation category is selected. Only devices belonging to the navigation category in the overall display shown in FIG. 8 are displayed.
[0050]
When the connection of devices belonging to this navigation category is displayed, the device that is actually set to be usable and the device that is set to be unusable are displayed in a distinguishable state. In FIG. 11, usable device blocks are displayed with solid lines, and device blocks set in an unusable state are displayed with broken lines. The controller 10 has a configuration in which the device connection display for each category is displayed and the remote control device or the like is operated to select a device that needs to be used at that time. Sometimes, a command not to operate the device is sent via the connected bus line.
[0051]
When this device selection processing is completed, the controller 10 displays the selection result on the monitor device 14. FIG. 12 shows a selection result display example in the navigation category. In this case, only the selected device is displayed.
[0052]
FIG. 13 shows a display example when another category is selected. In this example, a display example of devices belonging to the audio / video category is shown, and blocks of devices that can be used in the audio / video category are displayed by solid lines and cannot be used. The block of the device set to the state is displayed with a broken line. When the selection processing of the devices that can be used in this state is completed, the selection result display screen is displayed as shown in FIG. 14, and the blocks displayed with broken lines are not displayed.
[0053]
In this example, a mode is also prepared in which devices selected in each category (that is, devices in an active state) can be displayed simultaneously. That is, for example, FIG. 15 shows an example in which the selection results of the navigation category and the audio / video category are displayed simultaneously. In this example, the devices selected in the navigation category are connected and displayed by broken lines, and the devices selected in the audio / video category are connected and displayed by solid lines.
[0054]
In addition, although the example which performed the simultaneous display of the selection result of two categories was shown in FIG. 15, you may display simultaneously the selection result in all the prepared categories in the state which can distinguish each category. .
[0055]
As described above, according to this example, the setting of the state actually used in the connected device can be executed while the screen is displayed, and the desired state can be easily set. In this case, even when a portable device such as a video camera is connected, the connection of that device is displayed. As long as the device can be connected to the same bus line, the system can be freely connected by connecting the portable device. Can be assembled.
[0056]
In the above-described embodiment, the monitor device 14 directly connected to the controller 10 displays the screen such as the connection state. However, the video display unit included in another device connected via the bus line. In addition, the connection status or the like may be displayed.
[0057]

In addition, various items that can be operated other than commands such as selection of usable devices and selection of disks can be applied to the set items. For example, items such as a sound field and volume reproduced by an audio device, and an image quality of a video displayed on a monitor device may be set.
[0058]
In the above-described embodiment, the case where a video camera is connected as a portable device has been described. However, any device that can be connected to a bus line may be connected to form a system. In the above-described embodiment, the remote control signal is transmitted using an infrared signal, but may be transmitted wirelessly using another type of signal.
[0059]
In the above-described embodiment, a bus line based on a standard called IEEE 1394 is used. However, a system may be assembled using a bus line based on another standard. Furthermore, in the embodiment described above, the present invention is applied to a system installed in an automobile, but it is needless to say that the present invention may be applied to an information processing system installed in another vehicle.
