Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention, ExampleFor example, the present invention relates to a controller device that controls another device (target device) via a serial bus interface, such as an IEEE 1394 high performance serial bus, a control method using the controller device, and a control program.
[0002]
[Prior art]
For example, an interface for interconnecting digital AV devices such as a video cassette recorder (VCR) and a set top box (STB) to transmit / receive digital contents and control commands between devices "IEEE 1394 Standard for a High Performance Serial Bus" (hereinafter abbreviated as IEEE 1394).
[0003]
IEEE 1394 has two types of data: an asynchronous transfer mode used for normal data transfer and an isochronous transfer mode in which data transfer is guaranteed within a predetermined time (for example, 125 microseconds). It has a transfer mode. For example, in a multimedia system, an asynchronous transfer mode is used for command transfer in which transfer time delay is not a problem, and a synchronous transfer mode is used for transfer of moving images, audio data, and the like where time delay is a problem.
[0004]
In the IEEE 1394 bus, 64-bit fixed addressing is used, and its upper 16 bits indicate the address of a device (node) on the bus, and the lower 48 bits indicate an address space in each device. The upper 10 bits of the upper 16 bits are called a bus ID (bus_ID), and “1023” in which all bits are “1” in the local bus is used as the bus ID. The lower 6 bits of the upper 16 bits are called a node ID (node_ID), and when a new device is connected to the IEEE 1394 bus or a device is removed from the IEEE 1394 bus, each device is reset at the time of bus reset. Assigned in ascending order from 0. In the asynchronous transfer mode, a packet transfer source and a transfer destination device (node) are specified by this node ID.
[0005]
It is determined that an AV device equipped with IEEE1394 has an identification number called a node unique ID (node_unique_ID) of 64 bits, which is different for each device, in a memory storing device information called a configuration ROM (Configuration ROM). It has been. Since the external device connected to the IEEE 1394 bus can read the information of other devices stored in the configuration ROM in the asynchronous transfer mode, the information of the read device is connected to the IEEE 1394 bus. It can be used as information for uniquely identifying individual devices.
[0006]
Therefore, a technique for identifying a device connected to the IEEE 1394 bus by associating a node ID with a node unique ID (device type) (see, for example, Patent Document 1), or a node unique when a bus reset occurs. Techniques for acquiring an ID and identifying a device connected to an IEEE 1394 bus (see, for example, Patent Documents 2 and 3) have been proposed.
[0007]
The node ID is used to set a packet transfer address, but there is no guarantee that the same node ID is assigned to the same device every time the bus is reset. Therefore, in order to identify individual devices across bus resets and continue the same application, the node unique IDs of all devices existing on the bus are read every time a bus reset occurs, and the node ID It is necessary to memorize in association with.
[0008]
In the configuration ROM of consumer AV equipment, in addition to the node / unique ID, a text code indicating the vendor name, model name, etc. of the equipment is also stored. -It can also be presented to the user on a display (OSD; On Screen Display).
[0009]
By the way, “AV / C Digital Interface Command Set” (hereinafter referred to as this interface) defined by 1394TA (1394 Trade Association) as an interface specification for controlling AV equipment with IEEE1394. A command based on the specification is abbreviated as “AV / C command”). A packet frame sent from the controlling controller to the controlled target is called an AV / C command frame, and conversely, a packet frame sent from the target to the controller is called an AV / C response frame. AV / C command frame / response Asynchronous transfer mode is used for frame transfer.
[0010]
FIG. 5 is a diagram showing an AV / C command frame transfer format, and FIG. 6 is a diagram showing an AV / C response frame transfer format. “0000” at the head of the AV / C command frame / response frame is a CTS code indicating that this command set is an AV / C command. “Ctype” of the AV / C command frame represents a command type, and a setting value as shown in FIG. 7 is stored. “Subunit type (subunit_type)” represents the type of the subunit, and as shown in FIG. 8, for example, when “subunit_type” is “5”, it represents “Tuner”. “Subunit ID (subunit_ID)” is an identification number in the subunit as shown in FIG. 9, and up to five of the subunits can be identified. As shown in FIG. 10, “subunit_type” and “subunit_ID” are collectively referred to as an AV / C address. “Opcode” indicates the content of the command, and “operand [0] to [n]” indicate parameters attached to “opcode”. As shown in FIG. 11, for example, “opcode” is “B2_{( 16 )}"And" operand [0] "is" 70_{( 16 )}"Represents" Power on ". Further, “response” indicates a command acceptance status as shown in FIG.
[0011]
When a certain device (controller device) connected to the IEEE 1394 bus tries to control the operation of another device (target device), the controller device sends an AV / C command frame to the target device. The target device that has received the command examines the content of the AV / C command frame and sends an AV / C response frame indicating whether to accept the control content to the controller device. For example, when the target device that has received the AV / C command frame instructing “Power on” shown in FIG. 13 from the controller device accepts the control content, “response” is set to “response” as shown in FIG. An AV / C response frame “ACCEPTED” is sent to the controller device, and the state of the target device is changed to power-on. Conversely, when the control content from the controller device is not accepted, the target device sends an AV / C response frame with “response” set to “REJECTED” to the controller device as shown in FIG.
[0012]
Next, units and subunits used in AV / C commands will be described. A unit represents one AV device, and a subunit represents a functional unit existing in the AV device. For example, as shown in FIG. 16, in the case of a VCR 20c having both a tape recorder / player 21c and an analog tuner 22c, the VCR 20c is a unit, and the tape recorder / player 21c and the analog tuner 22c are subunits. AV / C commands can be sent to units or subunits.
[0013]
For example, from a controller device
"Subunit_type" = "1F_{( 16 )}(Unit) ",
"Subunit_ID" = "7 (ignore)",
“Opcode” = “B2_{( 16 )}",
"Operand" = "70_{( 16 )}Is sent to the VCR 20c, the entire VCR 20c is powered on.
[0014]
Meanwhile, from controller equipment
"Subunit_type" = "5_{( 16 )}(Tuner) ",
"Subunit_ID" = "0 (Subunit Instance number)",
“Opcode” = “B2_{( 16 )}",
"Operand" = "70_{( 16 )}Is sent to the VCR 20c, the tape recorder / player 21c in the VCR 20c (subunit with “subunit_ID” = “0”) is powered on.
[0015]
There is a “SUBUNIT INFO” command as an AV / C command for the controller device to check what subunit the target device has in the unit. The target device that has received this “SUBUNIT INFO” command informs the controller device of the type and number of subunits included in the own device (unit) using an AV / C response frame. FIG. 17 shows an example of the AV / C command frame of the “SUBUNIT INFO” command, and FIGS. 18 and 19 show examples of the AV / C response frame for the “SUBUNIT INFO” command of FIG. The AV / C response frame in FIG. 18 is a response example of the target device having the subunit configuration shown in FIG.
[0016]
In “operand [1] to [4]” of the AV / C command frame / response frame, the subunit type and the maximum ID of the subunit are set. In the example shown in FIG. 19, “operand [1]” includes “tuner (5)” as a subunit, and the maximum ID is “2”. “Operand [2]” includes “tape recorder / player (4)” as a subunit, and its maximum ID is “1”. “Operand [3] to [4]” has an invalid value “FF” to indicate that no other subunits are provided._{( 16 )}"Is set. That is, the example shown in FIG. 19 represents a target device including three tuners and two tape recorders / players.
[0017]
Note that “page” of “operand [0]” in FIGS. 17 to 19 is to supplement that information of only four types of subunits can be transferred with “operand [1] to [4]” in this command structure. For the unit that may have five or more types of subunits, the next subunit information can be read by designating this “page”.
[0018]
Depending on what kind of unit the target device is, the application that controls it varies. Therefore, before the controller device executes an application for controlling the target device, the controller device needs to recognize what type of device the target device is. The AV / C response frame can also be used as information for the user to select a desired control target device from the target devices connected to the IEEE 1394 bus.
[0019]
Since a bus reset occurs when a new target device is connected to the IEEE 1394 bus, the IEEE 1394 normally performs processing for recognizing the type of the connected target device after the bus reset is completed.
[0020]
FIG. 20 is a flowchart illustrating an example of a processing procedure in which the controller device recognizes the device type of the target device.
[0021]
First, when the controller device detects occurrence of a bus reset (step S21), the controller device reads a node / unique ID that can uniquely identify the device from all target devices on the IEEE 1394 bus (step S22), and creates a new target. It is determined whether or not the device is connected to the IEEE 1394 bus (step S23). As a result of the determination, if a new target device is not connected to the IEEE 1394 bus, the process is terminated. Conversely, if it is determined that a new target device is connected to the IEEE 1394 bus, the controller device reads the configuration ROM of the device for the new target device, that is, the target device for which the device type has not yet been acquired, Information such as the vendor name and model name is acquired (step S24). Further, the controller device sends a “SUBUNIT INFO” command to the target device, and acquires information on subunits included in the target device (unit) (step S25).
[0022]
Then, in order to determine the device type of the new target device, the following steps S26 to S28 are repeated for each subunit acquired in step S25. Normally, among the subunits described at the beginning (operand [1]) of the response frame of the “SUBUNIT INFO” command, the detailed information of the subunits in the ascending order of the subunit IDs from the subunit having the subunit ID “0”. To get.
[0023]
In step S27, the controller device performs detailed identification of the subunit. This detailed identification varies depending on the subunit type of the subunit and whether there is an application that controls it. For example, if the subunit is a tape recorder / player subunit, the D-VHS type and the DV type have different control methods depending on the application, and therefore, detailed identification of the subunit is performed for the tape recorder / player subunit. In addition, if the tuner subunit is not a control target, a criterion for determining the controller device such as not performing detailed identification of the subunit may be considered.
[0024]
In step S28, the controller device determines the type of the subunit using the detailed identification information of the subunit acquired in step S27 in addition to the subunit type. For example, if the tape recorder / player subunit is identified in detail as a D-VHS type, the controller device sets the type of the subunit to “D-VHS”, and if it is identified as a DV type in detail. The type of the subunit is “DV”. If the tuner subunit is not a control target, the controller device sets the tuner subunit to “not control target”. Since the VCR 20c having the subunit configuration shown in FIG. 16 has one tape recorder / player 21c and one analog tuner 22c, the controller device repeats the processing from step S26 to step S28 twice. It will be.
[0025]
The controller device determines the device type of the new target device in step 9 based on the subunit information acquired in the processing from step S25 to step S28, and returns to step S23.
[0026]
The controller device repeats the processes from step S23 to step S29 as many times as the number of target devices newly connected to the bus and determines the device types of all target devices, and the process ends.
[0027]
FIG. 22 is a flowchart showing an example of the device type determination process in step S29.
[0028]
First, the controller device selects the first subunit among the subunits identified in detail in step S28 (step S31), and determines whether or not the type of the selected subunit is a control target (step S32). ). Here, the determination “whether or not it is a control target” is based on whether or not the controller device has a control application corresponding to the selected subunit. For example, if the selected subunit type is a “DV” type tape recorder / player subunit, and the controller device has an application for a “DV” type tape recorder / player subunit, the controller device The selected subunit is determined to be a control target.
[0029]
If it is determined in step S32 that the selected subunit is a control target, the controller device sets the type of the subunit determined as the control target in step S36 as the target device (unit) type.
[0030]
If it is determined in step S32 that the subunit is not a control target, the controller device determines whether or not the selected subunit is the last subunit in step S33. If it is not the last subunit, the controller device selects the next subunit (step S34) and returns to step S32. If the result of determination in step S33 is the last subunit, the type of target device (unit) is set to “not controllable” (step S35).
[0031]
The controller device repeats the processing from step S32 to step S34 until a control target subunit is found, and if a control target subunit is found, registers it as the type of the target device (unit).
[0032]
For example, with respect to the VCR 20c having the subunit configuration shown in FIG. 16, the tape recorder / player 21c is recognized as a “D-VHS” type subunit, and the analog tuner 22c is recognized as “not subject to control”. Assuming that the controller device is a “D-VHS” type subunit, the controller device is the first subunit “D-VHS” type tape recorder / player 21c to be controlled. The VCR 20c device type is set to “D-VHS”.
[0033]
The controller device can select the corresponding application based on the device identification (D-VHS, DV, tuner, etc.) of the recognized target device, and can control the target device using the AV / C command.
[0034]
Further, as shown in FIG. 21, the controller device displays the device identification of the recognized target device together with information such as the vendor name and model name acquired from the configuration ROM on the OSD or the like. Can be used by the user as information for selecting the target device to be controlled.

[Problems to be solved by the invention]
By the way, when a plurality of subunits are included in one target device, the controller device does not always have an application corresponding to all the subunits. For example, when targeting the VCR 20c having the subunit configuration shown in FIG. 16, the analog tuner 22c cannot normally be controlled by the AV / C command of IEEE1394, and therefore the subunit of the analog tuner 22c is determined as the control target. There is no need to do. Therefore, the controller device only needs to determine only the tape recorder / player 21c among the subunits included in the VCR 20c as the control target.
[0039]
Conventionally, there was no target device that included multiple subunits that could be controlled by the controller device. Therefore, when determining the device type of the target device, multiple target units were included in the target device (unit). Even if the controller device is selected, the controller device selects the control target subunit first found among the plurality of subunits, and sets the detailed type of the selected subunit as the target device (unit). There was no problem in executing the application corresponding to that type. For example, in the case of the VCR 20c having the subunit configuration as shown in FIG. 16, the D-VHS type tape recorder / player 21c that is the first subunit to be controlled found is selected, and the detailed type of the subunit is selected. By using “D-VHS” as the type of VCR 20c (unit), no problem occurred.
[0040]
However, in such a method of selecting the first subunit to be controlled and making it a fixed device type, for example, a “SUBUNIT INFO” AV / C command as shown in FIG. Problems arise when controlling a target device that returns a response. Assuming that the controller device implements both applications that control the “D-VHS” type and “DV” type subunits, for a device having subunits as shown in FIG. From the tuner subunit ID = 0, it is determined whether it is a control target. For example, it is determined that all three tuner subunits are not control targets. Next, assuming that the subunit whose subunit ID of the tape recorder / player subunit is “0” is “DV” and the subunit whose subunit ID is “1” is “D-VHS”. The controller device selects the subunit of “DV” whose subunit ID is “0”, which is the first subunit to be controlled, and registers this “DV” as the device type of the VCR 20c that is the target device. Will do.
[0041]
In this case, the controller device cannot present to the user the existence of the “D-VHS” type subunit whose subunit ID is “1”, and cannot select the subunit. It is also impossible to start an application that controls a “D-VHS” type subunit.
[0042]
The present invention has been made to solve such a problem, and can control a desired subunit without changing a conventional user interface for a target device including a plurality of subunits to be controlled. It is an object of the present invention to provide a control method and a control program by a device and a controller device.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Throughout the drawings, the same or equivalent parts and components are denoted by the same or equivalent reference numerals, and the description thereof is omitted or simplified.
[0049]
FIG. 1 is a diagram illustrating a configuration example of the controller device 10 and the target devices 20a and 20b connected to the IEEE 1934 bus 30.
[0050]
The controller device 10 sets priority for setting the priorities for the subunits 21a to 25a included in the target device 20a and the subunits 21b to 24b included in the target device 20b recognized via the serial bus interface. Unit 12, a device type determination unit 13 that selects the subunit set with the highest priority among the subunits, and a device type presentation unit that presents the selected subunit to the user as the device type of the target devices 20 a and 20 b. 14, a priority storage unit 15 that stores the priority set by the priority setting unit 12, and a control unit 11 that controls each of the above units.
[0051]
The target device 20a includes a satellite digital tuner 21a (subunit ID = “0”), a terrestrial digital tuner 22a (subunit ID = “1”), and an analog tuner 23a (subunit ID = “2”) as tuner subunits. And a DV recorder 24a (subunit ID = “0”) and a D-VHS recorder 25a (subunit ID = “1”) as tape recorder / player subunits.
[0052]
The target device 20b includes an analog tuner 21b (subunit ID = “0”) as a tuner subunit, a DV recorder 22b (subunit ID = “0”) as a tape recorder / player subunit, and a D-VHS recorder 23b ( Subunit ID = "1"), and a hard disk recorder 24b (subunit ID = "0") is provided as a disk subunit.
[0053]
The controller device 10 gives priority to the types of subunits obtained as the detailed identification results of the subunits 21a to 25a and 21b to 24b included in the target devices 20a and 20b according to the necessity as a control target. Is set by the priority setting unit 12, and the type of the sub-unit having the highest set priority is determined by the device type determination unit 13 as the type of each target device 20a, 20b, for example, a device type presentation unit such as OSD 14 to the user. The priority setting unit 12 is provided with a user interface that allows the user to set the priority.
[0054]
FIG. 2 is an example of a priority setting screen 40 for the subunit type in the priority setting unit 12. Such a priority setting screen 40 is displayed to the user. For example, the user selects the subunit type 41 for which priority is to be set by using the mouse pointer 44 or the like, and selects the selected subunit type 41 by using the priority setting buttons 42 and 43 (in the example shown in FIG. 2, a D-VHS recorder). (Subunit ID = “1”) is selected) is set to a higher or lower priority. For example, as shown in FIG. 1, since the user already has a target device 20a having two tape recorder / player subunits, a DV recorder 24a and a D-VHS recorder 25a, the DV recorder 24a and the D-VHS recorder For the target device 20b including the two tape recorder / player subunits 23b and the hard disk recorder 24b, when the hard disk recorder 24b of the target device 20b is to be used as a “hard disk recorder”, the priority of the hard disk recorder 24b of the target device 20b By setting the unit higher than the units (21b to 23b), the device type of the target device 20b can be set to “hard disk recorder”. In the example shown in FIG. 2, the smaller the priority number, the higher the priority. However, the code indicating the priority is not limited thereto.
[0055]
In addition to allowing the user to set the priority setting for the subunit type in the priority setting unit 12, for example, when the controller device 10 is a digital tuner, an application for recording the broadcast on the recording device Therefore, for example, the controller device 10 itself can set the priority so that the D-VHS recorder 25a of the target device 20a has the highest priority.
[0056]
FIG. 3 is a flowchart illustrating a processing procedure for determining the device type executed by the controller device 10. 3 may be stored in a magnetic or optical recording medium as a computer program and read by the controller device 10 or supplied to the controller device 10 via a transmission medium. The control unit 11 of the controller device 10 controls each unit in the controller device 10 based on the computer program supplied via the recording medium or the transmission medium, and executes the following processing.
[0057]
In advance, the controller device 10 issues a “SUBUNIT INFO” command to the target device (for example, the target device 20a), and acquires detailed information of each subunit of the target device.
[0058]
First, the priority setting unit 12 sets the priority of the type of the subunit to be selected (for example, the D-VHS recorder 25a) among the subunits 21a to 25a of the target device (for example, the target device 20a) to the highest rank. Set (step S01).
[0059]
Next, the device type determination unit 13 selects the first subunit among the subunits identified by the response to the “SUBUNIT INFO” command (step S02), and the type of the selected subunit is the priority level to be selected. It is determined whether it is a thing (step S03).
[0060]
As a result of the determination in step S03, if it is determined that the type of the selected subunit is of the priority to be selected, the type of the selected subunit is set as the device type of the target device (unit) in step S07. .
[0061]
On the other hand, if it is determined in step S03 that the type of the selected subunit is not of the priority to be selected, then in step S04, the device type determination unit 13 determines that the selected subunit is the last one. It is determined whether it is a subunit. As a result of the determination, if it is not the last subunit, the device type determination unit 13 selects the next subunit (step S05) and returns to step S03.
[0062]
If the result of determination in step S04 is that the selected subunit is the last subunit, the device type determination unit 13 lowers the priority of the subunit type to be selected by one rank (step S06), and step S02. Return to.
[0063]
The device type determination unit 13 searches each subunit in turn until a subunit type of the priority is found by each processing from step S03 to step S05. If not found, the device type determination unit 13 lowers the priority and repeats the search from the first subunit once again.
[0064]
Through the above processing, the device type determination unit 13 registers the type of the subunit having the highest priority among the subunits included in the target device as the device type of the target device.
[0065]
Here, an example in which the controller device 10 executes the device type determination process illustrated in FIG. 3 for the target device 20a illustrated in FIG. 1 will be described below.
[0066]
First, in step S01, the priority setting unit 12 sets priorities as shown in FIG. 2, and selects “D-VHS recorder” having the highest rank priority as a selection target.
[0067]
In step S02, the device type determination unit 13 starts the determination from the satellite digital tuner 21a having the subunit ID = “0” among the tuner subunits stored at the head of the response of the “SUBUNIT INFO” command.
[0068]
In step S03, the device type determination unit 13 determines that the priority of the subunit (satellite digital tuner 21a) is lower than the priority of the currently selected subunit.
[0069]
In step S04, the satellite digital tuner 21a is not the last subunit in the target device 20a. Next, in step S05, the device type determination unit 13 determines the subunit ID = “1” as the next tuner subunit. The terrestrial digital tuner 22a is selected, and the process returns to the determination in step S03.
[0070]
The device type determination unit 13 makes this determination by using a tuner subunit with subunit ID = “0”, a tuner subunit with subunit ID = “1”, a tuner subunit with subunit ID = “2”, and a subunit ID = The tape recorder / player subunit of “0”, the tape recorder / player subunit of subunit ID = “1” are performed in this order, and the “D-VHS recorder” is the tape recorder / player subunit of subunit ID = “1”. When “25a” is selected, the determination result in step S03 is “Yes”, and the device type determination unit 13 sets “D-VHS”, which is the detailed type of the D-VHS recorder 25a, as the device type of the target device 20a. decide.
[0071]
As shown in the example of the device type presentation screen 50 in FIG. 4, the determined device type can be used as information for the user to select a device to be controlled by, for example, presenting it to the user as an OSD. At the same time, the controller can control the target according to an instruction from the user via the serial interface by associating the application for “D-VHS” with the target.
[0072]
For example, when the user wants to use the target device 20a as the terrestrial digital tuner 22a and sets the priority of the terrestrial digital tuner 22a to the highest rank on the priority setting screen 40 of FIG. When the tuner subunit (terrestrial digital tuner 22a) with unit ID = “1” is selected, the determination result in step S03 becomes “Yes”, and the device type determination unit 13 sets the device type of the target device 20a to “ Therefore, the target device 20a can be used as a terrestrial digital tuner.
[0073]
