Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an audiovisual (hereinafter, referred to as "AV") apparatus and a personal computer (hereinafter, referred to as "PC"), such as recording or reproducing data such as images and sounds. It relates to a device capable of performing processing and a device having a function of receiving or transmitting data such as images and sounds,
Especially when connecting multiple devices, the device user can connect the devices without being aware of the connection order, and remotely control other devices by operating any one of the connected devices It is related to a device having a function that can perform.

[0002]

2. Description of the Related Art In recent years, with the widespread use of AV equipment, it is difficult to have one device such as a CD player, a television receiver (hereinafter, referred to as "TV"), and a video player (hereinafter, referred to as "VCR"). It is no longer unusual. There is a growing demand for connecting these AV devices to each other to construct a so-called AV system. In such a case, since each remote controller (hereinafter, referred to as a remote controller) must be used to operate the devices, a situation has arisen in which the same number of remote controllers as connected devices are arranged on a desk.

[0003] Various ideas have been proposed in order to eliminate the inconvenience of having to use many remote controllers. For example, as disclosed in Japanese Patent Application Laid-Open No. 8-79847, a remote controller having a liquid crystal display (hereinafter referred to as a "remote controller") is prepared, and all the connected devices are registered in advance in the remote controller and displayed on the liquid crystal display. A method of operating a device by touching the registered registered device icon with a finger has been proposed. By using this remote control, control of all devices can be performed with only one remote control.

[0004]

However, when using the remote controller proposed in the above-mentioned Japanese Patent Application Laid-Open No. 8-79847, it is necessary to first connect devices in accordance with the use. For example, when connecting three of a VTR, a TV, and a satellite broadcast receiver, or when recording a video of the satellite broadcast receiver on a VTR, the output terminal of the satellite broadcast receiver and the VT
It is necessary to connect the input terminal of R, and if it is desired to display the image of the satellite broadcast receiver on the TV, it is necessary to connect the output terminal of the satellite broadcast receiver and the input terminal of the TV. If you also want to display the video of the VTR on the TV,
It is necessary to connect the output terminal of the VTR and the input terminal of the TV. As described above, if the user does not connect in consideration of the connection order, the advantage of the conventional remote controller cannot be utilized.

[0005] In addition, when a new device is added, the number of connection terminals may be insufficient, or it may be difficult to determine which is connected and which, and eventually all connections may be performed again. That is,
The work of connecting to build an information equipment system such as an AV system must be performed completely as before. Further, in the above-mentioned conventional invention, the icon of the connected device must be registered in the remote controller by itself, and the function (for example, recording and reproduction) of the device must be supplied to the remote controller from an IC card or a telephone line and stored. There is also a problem.

An object of the present invention is to allow a user to easily and freely connect a connected device without considering a method of connecting the device and without having to install a driver software or the like each time a connected device is added. To be able to operate.

[0007]

In order to achieve the above object, according to the present invention, a self model name memory for storing model name data indicating its own device name for each connected device, A self-function memory for storing such function data is provided. Also, at least one of the connected devices, a connected device memory that stores all connected model name data, a communication pair function memory that stores functions of two devices that exchange data, A display means such as a liquid crystal is provided in a remote controller or a housing of the device, or a display device connection terminal for connecting to some display device is provided.

With such a configuration, it is possible to display the model name data and function data received from another connected device and to operate the other connected device by transmitting the selected function to the selected device. become able to.

Note that the memory means a storage device or storage means.

As mentioned earlier, the job of recording the video received by the D-TV 104 on the D-VCR 103 is the
The case where the operation is performed by operating the RD 102 will be described with reference to a flowchart of FIG. 4 and an enlarged view of the operation button group and the display unit 203 used when operating the IRD 102 in the communication mode. Since other devices are operated by the IRD 102, such devices will be referred to as control devices. Also, the connected D
VCR 103, D-TV 104 and PC 106
It is assumed that the RD 102 has at least those equivalent to the self-function memory 312, the self-model name memory 311, and the connection interface 304 in FIG.

First, when a cable is connected to the IRD 102 or power is input (phase 401), initial settings are made in accordance with the digital interface specifications of the cable (phase 402). At this time, the ID numbers of all the connected devices are determined.

At this time, as a method of determining the ID number, for example, in the international standard IEEE 1394, IEEE 1394
-1995 standard (IEEE Standard fo)
ra High Performance Seria
As described in detail in (1 Bus), the parent-child relationship of all the devices is determined, and the ID numbers (node numbers of the nodes) of the leaf devices (devices to which no devices are connected other than the parent) are sequentially determined. ) Is determined, and the number is notified to all other devices.

In this embodiment, for example, the IRD 102
D number 102, D-VCR 103 is ID number 103, D
-It is assumed that the TV 104 is assigned to the ID number 104 and the PC 106 is assigned to the ID number 106.

Next, the process proceeds to a phase 403 in which the type of the device is known to other devices.

Here, there are two methods of transmitting what kind of model name oneself is to another device.

One is that immediately after the interface initial setting in the phase 402 is completed, the assigned own ID number and the own model name stored in the own model name memory 311 are transferred to all other devices via the connection interface 304. This is a method of transferring data to the connected device. In this method, all the connected devices having the connected device memory 308 at this point receive the model name data of all the devices and store the data in their own connected device memory 308. Can be stored. For example, in the present embodiment, the IRD 102, the D-VCR 103, the D-TV
All devices such as 104 transmit their model names to all the connected devices via the connection interface, and store all the connected device names.

Another method is that, after the interface initialization in the phase 402 is completed, all devices are in an idling (waiting for request) state. During this time, if the model name data request data is received via the connection interface 304, the request source is Is to transfer your own model name to For example, in the present embodiment, the IRD 102 is a D-VC
A model name is requested from the R103 or D-TV 104, and the model name data of all the models transmitted in response to the request is stored in its own connected device memory 308. At this time, the model name request data is transferred to all the connected devices by pressing the communication mode button of the IRD 102.

The former advantage is that the time required for stepping up to the next phase 404 after the user presses the communication mode button (selects it as a control device) is reduced. On the other hand, the latter advantage is that the memory capacity can be reduced because the model name data does not need to be received unless it is selected as the control device.

FIG. 21 shows an example of a transfer data structure when requesting model name data. Reference numeral 2101 denotes header data indicating that the model name data request flag 2103 follows the digital interface standard for connecting the devices, and reference numeral 2102 denotes a transmission source ID number. Display character data for displaying characters so as to be understood by the user is stored in the self-model name memory 311 as shown in FIG. The parentheses () mean that a character code expressing the inside of the parentheses is stored.

FIG. 9 shows an example of a transmission data structure when an ID number and a model name are transferred to another device. Reference numeral 901 denotes header data indicating that the model name data follows the protocol of the digital interface, 902 denotes its own ID number, and 903 denotes the model name.

To correctly display the display character data on the receiving side, a means for converting the character data into characters on the receiving side is required. In the IRD 102, the communication mode screen display control unit 306 in FIG.

In phase 403, while transmitting its own model name and ID number, the ID number and model name of another device transmitted via the digital interface are stored (along with its own ID number and model name) in the connected device memory. 308. However, in the case of a method in which the control device requests model name data from another device (the latter method of transferring the two model name data), it is not necessary to transmit at least its own model name.

As shown in FIG. 7, the connected device memory 308 stores an ID number 701 and a model name character display code 702 corresponding thereto. The parentheses () in 702 mean a character code expressing the inside of the parentheses. Up to this point, the preparation for determining a device to transmit data and a device to receive data is completed.

FIG. 6A shows the self model name memory 31.
1 shows an example of data storage. As shown in FIG. 3, an area having one memory (self-information memory 313) is used as a self-model name memory area, and the remaining area is used as a self-function memory area. The data may be stored in the self-model name memory area.

FIG. 6B shows an example of data storage in the self information memory 313. 604 is a self-model name memory area, and the remaining areas 602 and 603 are self-function memory areas. 6
04 is own model name data, and 602 is a function flag, which is a command number for executing a function corresponding to the data sent from outside. Reference numeral 603 denotes a function name for displaying characters so that the user can understand what function the function flag 602 is. 6 same as 601
Braces (03) of 03 and 604 mean that a character code expressing the inside of the parentheses is stored.

Next, the process proceeds to a phase 404 for determining a source device and a target device as a pair for exchanging data. Here, the “source device” refers to a device that transmits information, and the “target device” refers to a device that receives information transmitted from the source device. I
The phases 404 to 407 will be described with reference to FIG. 5 in which the communication mode operation unit 203 in the RD 102 is enlarged.

The communication mode is turned on by pressing the communication mode button 210 in the previous phase. As a result, a cursor is displayed at the position 501 of the source side area 506 displayed on the communication mode display LCD 209.
If the communication mode button 210 is not pressed, the communication mode is turned off and the IRD 102 is operated alone, and the channel is set by operating the button group 202 in FIG. 2 or the attached remote controller.

When the select button 206 is pressed, the model name (702 in FIG. 7) stored in the connected device memory 308 is sequentially displayed at the position 501. When “D-TV” is displayed, stop pressing the button 206. Then, the user presses the cursor movement button 207 to move the cursor to the position of 502. By moving the cursor from the position of 501,
It is considered that the D-TV 104 has been selected as the source device, and the D-TV 1 stored in the connected device memory 308 has been selected.
D-TV using the ID number 04 (104 in FIG. 7)
Requests function data (a flag for causing a function of the D-TV to be executed by an external operation, and a character code representing the function) to the function 104. When the requested D-TV function data is sent, it is stored in the communication pair function memory 309 (phase 405).

FIGS. 22 and 23 show a transmission data structure example and a function data transmission data structure example at the time of a function data request, respectively. In FIG. 22, reference numeral 2201 denotes a header indicating that a function data request flag follows in accordance with the standard of a digital interface for connecting devices, reference numeral 2202 denotes an ID number of a transfer source of the data, and reference numeral 2203 denotes a function data request flag. In FIG. 23, reference numeral 2301 denotes a header indicating that the function data follows following the standard of the digital interface for connecting the devices, reference numeral 2302 denotes an ID number of a transfer source of the data, and reference numeral 2303 denotes the function data.

Since the D-TV 104 has a self-function memory like the IRD, when a function request signal is received,
The data (functional data) stored in the self-function memory is transferred via the digital interface to the IRD 102 that is the request transmitting device.

FIG. 8 shows an example of data storage in the communication pair function memory 309. The communication pair function memory 309 stores function flags 803 and 804 and character code data 805 and 806 representing the function flags in a source device data area 801 (upper half frame in FIG. 8) and a target device area 802 (FIG. 8 (the lower half frame). Note that separate memories for the source device and the target device may be prepared and used. By pressing the select button 206, the model name (D) stored in the source device area 801 is displayed.
-TV) Character data 805 of the subsequent function data is sequentially displayed in the cursor area 502 of FIG. 5, and when the desired function is displayed, the pressing of the select button 206 is stopped. This completes the setting of the source device (phase 40).
6).

Next, returning to the phase 404, a target device is determined. Cursor move button 205 or 2
By pressing 07, the cursor is moved to a position 503 in the target device display area 507. The determination of the target device and its function is performed in exactly the same manner as the operation performed on the source device, and the desired device and function are selected (phase 404, phase 405). However, the communication pair function memory 309 uses the target device area 802. In the example of FIG. 5, the D-TV 10
4 shows a state in which channel 1 is recorded on the D-VCR 103.

When the source device, the target device and their functions have been selected (phase 406), the start button 208 is finally pressed (phase 4).
07), the D-TV 104 selects “Channel 1 and
The command “Transmit to D103 (D-VCR)” is transferred, and “ID104 (D-VCR) is transmitted to D-VCR103.
Receive the data transmitted from the TV) and record (record) ”via the digital interface.

At this time, the data transmitted by the IRD 102 transfers the ID number 1202 of the communication partner together with the function flag 1203 as shown in FIG. That is, D
-For the TV 104, the ID number of the D-VCR 103 and the function flag field 1
A command number 01 for receiving channel 1 is transmitted to 203. For the D-VCR 103, the ID field 1202 shows the ID number of the D-TV 104, and the function flag field 1203 shows the command number 0 to be recorded.
2 (in this embodiment, the command number corresponding to the recording function is “02” as indicated by reference numeral 804 in FIG. 8).

Thus, each device can recognize where data should be transferred or where data should be transferred. Note that field 12
01 is header data indicating that the following data is a function flag according to the protocol of the digital interface to be connected.

Here, when the communication is started, the character 505 "communicating" may be displayed on the communication mode display LCD 209, indicating that the communication is being performed. The control device (in this case, the IRD 102) may be provided with a timer function, and a communication start time and an end time may be set by pressing a timer button (not shown) before pressing the communication start button. However, in this case,
When the set time comes, the control device transfers the function flag in the packet of FIG.

When the communication start button is pressed, the settings and ID numbers of the respective devices at the start are stored in the communication setting memory 310. Regarding the setting of the communication pair, either the source device or the target device may be performed first.

In the above-mentioned method of transferring the model name data (the method of transferring the own model name in response to the model name request), the model name data request and the response, and the function data request Although the responses are made in different phases (phases 403 and 405), both the model name data and the function data may be obtained by one request. That is, the control device transfers a function data request including model name data to all other devices.
Upon receiving this request, the connected device transmits its model name data and function data together. The control device separates the transmitted function data including the model name data into model name data and function data, and
And stored in the communication pair memory 309.

FIG. 24 shows an example of the data structure when model name data and function data are transmitted together. Reference numeral 2401 denotes a header indicating that the model name data 2403 and function data 2404 follow together according to the standard of the digital interface, and reference numeral 2402 denotes an ID number of a transmission source.

Now, the channel 1 of the D-TV 104 is set to D
-When the communication for recording on the VCR is set, and another communication is set, for example, when a certain program received by the IRD 102 is reserved for recording on the D-VCR 103, the communication program button 211 may be pressed. Can be set. When the button 211 is pressed, 1001 shown in FIG.
A character indicating the next communication setting is displayed, as shown in, and a new setting screen is displayed. Just as when the first communication is set, the source device and the target device can be set and the second communication can be started. Further, by repeating the same thing, it is possible to start a plurality of communications with three, four,....

After starting communication, a communication confirmation button 2
By pressing 13, the communication settings stored in the communication setting memory 310 are displayed on the communication mode display LCD 209 as shown in FIG. At this time, the stop button 20
By pressing 8, a signal of "end communication" is transmitted to the IDs of the D-TV and the D-VCR stored in the communication setting memory 310, and the communication can be stopped.

The description so far has been made from the viewpoint of the IRD 102, that is, the control device, but this time, the description will be made from the viewpoint of the controlled device. Here D
This will be described using the VCR 103.

FIG. 11 is a flowchart showing how the D-VCR 103 (controlled device) is controlled from the control device. Phase 401, phase 402, and phase 403 are completely the same as the case of the control device, and the description is omitted.

In phase 1101, the process waits until another device requests function data (using polling, interrupt, timer, etc.). When a function data request is issued, the function flag stored in the self-function memory and the display character data are transferred to the request source (phase 110).
2), keep waiting until a function flag (function command) is transmitted (phase 1103). Since a command for a function is transmitted from the control device in a data structure as shown in FIG. 12, when this (function flag) is received, the function (for example, recording) to which the flag is assigned is executed (phase 1104).

Since the ID number of the data transmission source (D-TV in this example) is also transmitted together with the function flag as shown in FIG. 12, the D-VCR 103 determines where the data is transmitted from. Can be recognized. After executing the function, the phase 1101 is prepared in preparation for the next communication.
Waits for the function request signal again.

As described above, all connected devices have their own model name memory 311 and their own function memory 312 (or their own information memory 313), and at least one of them has a communication with the connected device memory 308. By having the pair function memory 309, the user can operate all the connected devices by operating only one device (having the connection device memory 308 and the communication pair function memory 309).

The connected device memory, the communication pair function memory, and the communication setting memory may not be provided separately, but may be used by dividing an area of one memory (the RAM 314 in FIG. 3). Also self-functional memory,
Since the contents stored in the self-model name memory and the program ROM are information that cannot be rewritten,
Instead of separately providing memories, one memory area may be divided and used.

Further, regarding the communication mode display LCD,
The following can also be performed. (1) The setting of the source device and the target device is performed on the same screen (both the source device setting and the target device setting are displayed simultaneously). However, the setting screen of the target device is displayed after the setting of the source device is completed. (2) Separate LCDs are provided for each of the source device settings and the target device settings so that the settings can be selected separately. (3) The communication mode display LCD 209 is provided not on the device as shown in FIG. 2 but on the remote controller.

FIGS. 25 and 26 show examples of the IRD main body and the remote controller in the case of the above (3). Reference numeral 2501 denotes an IRD body without a communication mode display LCD;
Is a light receiving unit for receiving a signal from the remote controller. In remote controller 2601, reference numeral 2602 denotes a communication mode display LCD.
(Equivalent to 209), 2603 is a button for controlling the power of the IRD, and 2604 is a reception channel of the IRD (202)
2 are the same as those in FIG. Ii, and perform the same operations.

When a device such as a D-TV 104 having a display for displaying an image is used as the control device, the communication mode display LCD 209 is not provided separately from the display for displaying the image, but is used as a control device in FIGS.
The communication setting menu screen as shown in FIG. 0 may be displayed on the same display.

FIG. 13 shows an example of an external view of the D-TV 104 as such a device. Reference numeral 1301 denotes a display for displaying a received image and a communication setting menu.
A power switch 1303 is a video button for displaying a received image. The other buttons have the same functions as those described with reference to FIG. 2 (the same numbers are assigned).

When the communication mode button 210 is pressed, the D-TV 104 becomes a control device, and a communication setting menu is displayed on the display 1301. By pressing the cursor movement buttons 205 and 207 and the select button 206, the source device and the target device are set, and communication is started by the start button 208. When the video button 1303 is pressed, the display 1301 changes from the communication mode display screen to a normal received video display screen. To set another communication, the communication mode button 210 is pressed again. That is, the D-TV 104 has two screen display modes, a received video display and a communication mode display.
03 can be switched.

In the embodiment described above, the self model name memory 311, the self function memory 312, the self information memory 3
The data stored in 13 is character data (as in FIGS. 6, 7, and 8), and an example in which the connected device converts the character data into characters and displays the characters on a display device will be described. Have been.

This is, for example, the character conversion system A. Each device stores a character code according to the character conversion method A in its own model name memory, its own function memory, and its own information memory. Each device can also display the received character data on the screen according to the character conversion method A. However, a certain connected device stores a character code that does not follow the character conversion method A, and if this is transmitted to another device, the character code will not be displayed correctly as a matter of course. Here, let's change the viewpoint a little and consider using pictures and symbols instead of letters. That is, an embodiment will be described in which all the connected devices in FIG. 1 employ the graphic display system A instead of the character conversion system A.

In the present embodiment, the video received on channel 2 of the IRD 102 is
The case of recording in the CR 103 will be described. Here, IRD102, D-VCR103, DT
V104 and PC 106 are both self-information memories 313.
It is assumed that each stores model name data and function data in a data format according to the graphic display method A. In addition, the D-TV 104 has a communication setting memory 310 and a connected device memory 308, and displays data according to the graphic display method A correctly on the screen, and can execute an accompanying operation. Assume that it has a part 306. Further, in the present embodiment, the self-model name data and the self-function data are put together to form self-information data 313 as self-information data.
The self-information data (self-model name and self-function data) is stored in the connection device memory together with the ID number, so that the communication pair memory 309 for storing the self-function data is unnecessary. There is.

FIG. 16 shows an example of self-information data stored in the self-information memory of the D-TV 104. 1601 is D
-Self-information data obtained by converting the TV model name data and the function data collectively by the graphic display method A. Here, the brackets [] indicate that the self-information data of the device in the brackets is converted by the graphic display method A.

FIG. 15 shows a second external view of the D-TV 104. The numbers in the figure that do not have 15 at the beginning are the numbers already described, and the description thereof will be omitted. FIG.
The D-TV 5 can select an item by directly touching the screen with a finger without using the cursor movement buttons 205 and 207 and the select button 206 unlike the D-TV of FIG.
By hitting the selected cursor position twice consecutively,
It is assumed that the same effect as pressing the select button 206 is obtained.

First, by pressing the communication mode button 210 in FIG. 15, the device D-TV 104 is selected as a control device. The D-TV 104 requests self-information data from all connected devices.
