Description

  The present invention relates to a reservation recording method in the case of performing reservation recording using a reservation recording device compatible with a home network.

  In order to enable detection and control of devices connected to the network, a protocol called universal plug and play (hereinafter referred to as UPnP) has been standardized.

  UPnP uses standard TCP / IP (Transmission Control Protocol / Internet Protocol) and Internet protocols to obtain information about the presence and functions of other devices connected to the network, and to provide other devices with their own functions. This function realizes a function such as notification, etc., which makes it easy to set up, set and add peripheral devices.

  The basic building blocks of a UPnP network are devices, services, and control points. A UPnP device is a device that stores a service that is a minimum unit of control. For example, in the case of a VTR device, it can be expressed as being composed of a tape feed service, a tuner service, and a clock service. it can. The control point is a controller that can detect and control other devices.

  A UPnP device newly connected to the network first acquires an address for joining the network. This address is acquired by a DHCP (Dynamic Host Configuration Protocol) client of each device. Obtained by automatically assigning an address from the server. When a UPnP device newly connected to the network is assigned an address and becomes communicable, the device or service GENA (General Event Notification Architecture) advertisement is transmitted by multicast (UDP: User Datagram Protocol) and connected to the network. Send a search message to other devices to announce their presence and advertise the service. This advertisement must be retransmitted before it expires. In addition, when the device goes offline, the device transmits a message clearly indicating leaving before going offline.

  A control point on the network has a capability of multicasting a Simple Service Discovery Protocol (SSDP) search message and searching for related devices and services (M-SEARCH). The search message is in the form of an SSDP request sent using HTTP MU (Hyper Text Transfer Protocol Multicast over UDP), and includes the type and ID of the device or service that is defined by the UPnP Steering Committee or is unique to the vendor. It is.

  All devices need to listen to the standard multicast address of this SSDP search message and respond if the service of the device matches the search criteria of the search message.

  A response to the search request is transmitted to the IP address of the control point that started the search using unicast UDP (User Datagram Protocol) with an SSDP header.

  Using the above technology, for example, when the control point is a device that performs scheduled recording setting (hereinafter referred to as a scheduled recording setting device), it is a device that performs scheduled recording (hereinafter referred to as a scheduled recording device). The devices are searched, and all the reserved recording devices on the network are displayed. For example, a hard disk recorder (hereinafter referred to as PVR) can be selected.

  The response to the received search request includes a URL (Uniform Resource Locator) that can acquire the Device Description. In order to obtain the UPnP Device Description, the control point issues an HTTP GET request to the URL of the search message, and the device returns the Device Description.

  Device Description lists information on the service set provided by the device type, as well as device-related properties such as a device name and an icon in an XML (eXtensible Markup Language) format.

  A pointer (URL) to the Service Description is included in the Device Description document, and the Service Description can be obtained by the same method as the Device Description. Service Description is an XML document in which information on services provided by a device is described. Specifically, a content directory service for displaying a list of AV contents, and an AV transport for controlling AV streaming. Services etc. are defined by UPnP Steering Committee. In addition to services defined by these UPnP steering committees, it is possible to provide vendor-specific services. For example, it is possible to define a scheduled recording service for accepting and executing scheduled recording setting information.

On the other hand, reservation recording devices such as PVRs that can be connected to the network have started to be commercialized, and reservation recording settings are set for these reservation recording devices from a reservation recording setting device such as a PC via a home network. It has become a fully conceivable situation.
Universal Plug and Play Device Architecture 2000

  However, when a user sets reservation recording for a reservation recording device such as a PVR compatible with a home network from a reservation recording setting device such as a PC, various parameters and parameter values included in the reservation recording setting information Depending on the combination, there may occur a case where the scheduled recording set by the user is not accepted by the scheduled recording device. In such a case, the user must select the parameter value again and perform the scheduled recording again. In other words, there was a problem that the user was forced to perform cut-and-try reserved recording.

  In order to solve the above-described problem, in the scheduled recording method of the present invention, a scheduled recording setting device and a plurality of scheduled recording devices are connected to each other via a home network, and the scheduled recording setting device is input by a user. In the scheduled recording method, the scheduled recording device executes the scheduled recording based on the scheduled recording setting information received from the scheduled recording setting device. Checks whether there is an unacceptable parameter value in each parameter value of the parameter group included in the received scheduled recording setting information, and if there is an unacceptable parameter value The parameter value is immediately changed to an acceptable parameter value and accepted, and the changed reservation recording setting information is changed to the reservation recording setting. It is characterized in that to send to the vessel.

  In order to solve the above-described problem, another scheduled recording method according to the present invention includes a scheduled recording setting device and a plurality of scheduled recording devices connected to each other via a home network, In the scheduled recording method, the scheduled recording setting information input by the user is transmitted to the scheduled recording device, and the scheduled recording device executes the scheduled recording based on the scheduled recording setting information received from the scheduled recording setting device. Regardless of whether or not there is an unacceptable parameter value, the timer recording device temporarily receives the received timer recording setting information and transmits information indicating completion of acceptance of the timer recording setting information to the timer recording setting device. In the parameter values of the parameter group included in the scheduled recording setting information received immediately thereafter, the unacceptable parameter value If there is an unacceptable parameter value, the parameter value is changed to an acceptable parameter value, and the changed reservation recording setting information is changed to the reservation recording setting device. It is characterized by transmitting to.

  According to the timer recording method of the present invention, even if the timer recording parameters and parameter values are intricately mixed, the user can easily accept the parameters of the timer recording device designated by the user and the Scheduled recording can be set according to the parameter value.

  Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1)
FIG. 1 is a block diagram for explaining a reserved recording method according to Embodiment 1 of the present invention. In FIG. 1, reference numeral 1 is a reserved recording device, for example, a PVR having two recording devices, a DVD drive and a hard disk drive (hereinafter referred to as HDD), and 2 is a personal computer (hereinafter referred to as PC) as a reserved recording setting device. 3 is a home network, 4a and 4b are network interfaces for enabling PVR1 and PC2 to be connected to each other via the home network 3, 11 is a tuner built in PVR1, and 12 is a DVD drive. Recording means built in PVR 1 having two recording devices of HDD, 13 is a reserved recording setting information list storage unit for storing a list of reserved recording setting information of PVR 1, and 14 is a UPnP service for providing reservation recording service with UPnP , 15 are preset values of the reserved recording parameters received. 16 is a parameter value changing unit that changes the value of the scheduled recording parameter to a settable parameter value, and 21 is one of the components of the PC 2. A UPnP control point 22 is a graphic user interface (hereinafter referred to as GUI) of the PC 2. Moreover, FIG. 2 is a figure which shows the flowchart of the reservation video recording method in Embodiment 1 of this invention.

  Hereinafter, the reserved recording method according to the first embodiment of the present invention will be described with reference to FIGS. In order to make a reservation recording of a certain broadcast program, the user operates the PC 2 while watching the GUI 22, and is a reservation recording device connected on the home network 3 based on the UPnP procedure shown in the above "Background Art". PVR1 is discovered and reservation recording is set for PVR1 (step S1 in FIG. 2). Table 1 shows an example of scheduled recording setting information (scheduled recording parameters and parameter values) desired by the user when PVR1 is selected as the scheduled recording device.

  The parameters and parameter values that are the scheduled recording setting information created in step S1 in FIG. 2 are the same as the Create Object SOAP (Simple Object Access Protocol) action used in the content directory service described in the above “Background Technology”. The XML document representing the information is stored in the argument of the CreateRecordSchedule SOAP action and transmitted to the PVR 1 (step S2 in FIG. 2). Specifically, the SOAP action is transmitted from the UPnP control point 21 that is one of the components of the PC 2 to the UPnP service 14 that is one of the components of the PVR 1 using the HTTP protocol. FIG. 3 shows an example of the CreateRecordSchedule SOAP action that stores the XML document representing the scheduled recording setting information shown in Table 1. Actually, when storing in the argument, it is stored by performing XML escape, but in FIG. 3, it is expressed in a form before escape in order to improve visibility.

  The UPnP service 14 that is one of the components of the PVR 1 that has received the scheduled recording setting information by the CreateRecordSchedule SOAP action transmits the received scheduled recording setting information to the parameter value comparison unit 15. In the parameter value comparison unit 15, each parameter value of the parameter group (for example, each parameter value of the parameter group shown in Table 1) included in the scheduled recording setting information received from the UPnP service 14 and the recording unit 12 of the PVR 1 Each parameter of the parameter group included in the scheduled recording setting information received from the UPnP service 14 is compared with “each parameter value of a preset parameter group” as a parameter acceptable to each recording device provided. It is checked whether or not the value is composed of an acceptable parameter value of the recording apparatus designated as the recording destination in PVR1 (step S3 in FIG. 2).

  In the example shown in Table 1, the DVD drive of the two recording devices possessed by the PVR 1 is selected as the recording destination and XP is set as the recording mode. However, in the DVD drive, XP is set as the recording mode. Since it cannot be selected, the parameter value comparison unit 15 determines that the parameter value is not configured with an acceptable parameter value of the DVD drive, and transmits this scheduled recording setting information to the parameter value change unit 16. In the parameter value changing unit 16, the recording mode (XP) in the scheduled recording setting information received from the parameter value comparing unit 15 is set as a DVD drive with reference to “each parameter value of a preset parameter group”. The recording mode is changed to LP which is an acceptable recording mode (step S4 in FIG. 2). The reserved recording setting information changed in this way is stored in the reserved recording setting information list storage unit 13 together with other reserved recording setting information that is not changed (step S5 in FIG. 2). An example of the reserved recording setting information list stored in the reserved recording setting information list storage unit 13 is shown in FIG. Simultaneously with a series of processing operations from step S3 to step S5, the UPnP service 14 generates a CreateRecordSchedule SOAP action response (step S6 in FIG. 2) and returns the generated response to the UPnP control point 21 (FIG. 2). Step S7). FIG. 5 shows an example of the response of the generated CreateRecordSchedule SOAP action.

  The PC 2 that has received the CreateRecordSchedule SOAP action response from the UPnP service 14 displays the changed scheduled recording setting information on the GUI 22 (step S20 in FIG. 2). The GUI 22 notifies the user that the parameter value has been changed by displaying the changed parameter as shown in Table 2 in bold or by changing the color. .

  In the first embodiment, as an example of changing the acceptable parameter value, the recording mode parameter value is changed from XP to LP. However, the recording mode parameter value remains XP and the recording destination is changed. You may change into HDD which can record in XP recording mode.

  Alternatively, the priority order of each parameter may be determined in advance and stored in a reserved recording device (for example, PVR1), and the parameter value of a parameter with a lower priority order may be changed from among several parameters.

  In the first embodiment, the reservation recording device connected to the home network 3 is only the PVR 1 for simplicity of explanation, but a plurality of reservation recording devices such as a DVD recorder, a video tape recorder, or a hard disk recorder are used. A case where the recording device is connected to the home network 3 is also assumed. In such a case, first, a reserved recording device to be used for recording is selected by the user with the reserved recording setting device, and thereafter, the reserved recording may be performed by the method described in the first embodiment.

  As described above, according to the first embodiment of the present invention, the PVR 1 that is the reserved recording device receives the parameters and parameter values that are the reserved recording setting information set by the user using the PC 2 that is the reserved recording setting device. If the parameter value that is the received reservation recording setting information includes a parameter value that PVR1 cannot accept, PVR1 changes the parameter value that cannot be accepted to an acceptable parameter value, and changes the reserved recording after the change. By configuring so that the setting information is returned to the PC 2, even if the parameter and the parameter value combination of the scheduled recording setting information set by the user cannot be accepted, the user repeats the scheduled recording setting many times. Without setting up so-called cut-and-try, set up scheduled recording efficiently and It can be carried out in sure.

(Embodiment 2)
FIG. 6 is a block diagram for explaining a reserved recording method according to Embodiment 2 of the present invention. The configuration in the second embodiment is almost the same as the configuration shown in FIG. 1 in the first embodiment. The difference from the first embodiment is that the reservation recording device PVR 10 is reserved as one of the components. The point that the recording setting information cache 17 is provided is different from the timing at which the PVR 10 transmits the change of the reserved recording setting information to the PC 2 that is the reserved recording setting device. FIG. 7 is a diagram showing a flowchart of the reserved recording method according to Embodiment 2 of the present invention.

  Hereinafter, the reserved recording method according to the second embodiment of the present invention will be described with reference to FIGS.

  In order to make a reservation recording of a broadcast program, a user operates the PC 2 which is a reservation recording setting device while watching the GUI 22, and is connected to the home network 3 based on the UPnP procedure shown in the above "Background Art". The PVR 10 that is the reserved recording device is found, and the reservation recording is set for the PVR 10 (step S11 in FIG. 7). Table 1 shows an example of reserved recording setting information (reserved recording parameters and parameter values) desired by the user when the PVR 10 is selected as the reserved recording device.

  The parameter group and each parameter value, which are the scheduled recording setting information created in step S11 in FIG. 7, represent the scheduled recording setting information as in the CreateObject SOAP action used in the content directory service described in the above “Background Art”. The XML document is stored in the argument of the CreateRecordSchedule SOAP action and transmitted to the PVR 10 (step S12 in FIG. 7). Specifically, the SOAP action is transmitted from the UPnP control point 21 which is one of the components of the PC 2 to the UPnP service 14 which is one of the components of the PVR 10 using the HTTP protocol. An example of the CreateRecordSchedule SOAP action storing the XML document representing the scheduled recording setting information shown in Table 1 is shown in FIG. Actually, when storing in the argument, it is stored by performing XML escape, but in FIG. 3, it is expressed in a form before escape in order to improve visibility.

  The UPnP service 14 that is one of the components of the PVR 10 that has received the timer recording setting information by the CreateRecordSchedule SOAP action immediately generates a response of the CreateRecordSchedule SOAP action (step S13 in FIG. 7), and the generated response is sent to the PC 2 A response is sent to the UPnP control point 21 (step S14 in FIG. 7), and at the same time, the received scheduled recording setting information is transmitted to the scheduled recording setting information cache 17. The timer recording setting information cache 17 temporarily stores the timer recording setting information received from the UPnP service 14 (step S15 in FIG. 7). FIG. 8 shows an example of a response to the CreateRecordSchedule SOAP action generated by the UPnP service 14.

  In the parameter value comparison unit 15, each parameter value of the parameter group included in the scheduled recording setting information temporarily stored in the scheduled recording setting information cache 17 (for example, each parameter of the parameter group shown in Table 1) Value) and “each parameter value of a preset parameter group” as parameters acceptable by the PVR 10, and are included in the scheduled recording setting information temporarily stored in the scheduled recording setting information cache 17. It is checked whether each parameter value of the parameter group is configured with an acceptable parameter value of the PVR 10 (step S16 in FIG. 7).

  In the example shown in Table 1, the DVD drive of the two recording devices of the PVR 10 is selected as the recording destination and XP is set as the recording mode. However, in the DVD drive, XP is set as the recording mode. Since it cannot be selected, the parameter value comparison unit 15 determines that the parameter value is not configured with an acceptable parameter value of the DVD drive, and transmits this scheduled recording setting information to the parameter value change unit 16. In the parameter value changing unit 16, the recording mode (XP) in the scheduled recording setting information received from the parameter value comparing unit 15 is set as a DVD drive with reference to “each parameter value of a preset parameter group”. The recording mode is changed to LP which is an acceptable recording mode (step S17 in FIG. 7). The reserved recording setting information changed in this way is stored in the reserved recording setting information list storage unit 13 together with other reserved recording setting information that is not changed (step S18 in FIG. 7). An example of the reserved recording setting information list stored in the reserved recording setting information list storage unit 13 is shown in FIG.

  Simultaneously with a series of processing operations from step S16 to step S18, the UPnP service 14 generates an Event message for notifying the changed parameter (step S19 in FIG. 7). An example of the Event message generated in the UPnP service 14 is shown in FIG.

  The UPnP service 14 transmits the generated Event message to the UPnP control point 21 of the PC 2 (Step S20 in FIG. 7). This Event message is transmitted to a UPnP control point that has requested subscription to the Event message in advance, and in the second embodiment of the present invention, the UPnP control point 21 has previously requested subscription to the Event message. The case is shown. Details of the UPnP Event message are described in detail in Non-Patent Document 1 shown in the “Background Art” above.

  The PC 2 that has received the Event message displays the scheduled recording setting information updated based on the changed parameter value information included in the Event message on the GUI 22 (step S21 in FIG. 7). In the GUI 22, the parameter value changed as shown in Table 2 is displayed in bold or displayed in a different color to notify the user that the parameter value has been changed. To do.

  In the first embodiment, as an example of an acceptable parameter change, the recording mode parameter value is changed from XP to LP. However, the recording mode parameter value remains XP and the recording destination is XP. The recording mode may be changed to a recordable HDD.

  Alternatively, the priority of each parameter may be determined in advance and stored in a reserved recording device (for example, PVR 10), and the parameter value of a low priority parameter may be changed from among several parameters.

  In addition, when there are two or more parameters to be changed, they may be transmitted by storing them in an event message in the CSV format. An example of the CSV format event message is shown in FIG.

  As described above, according to the second embodiment of the present invention, the parameter group which is the timer recording setting information set by the user using the PC 2 which is the timer recording setting device and each parameter value are the timer recording devices. When the PVR 10 receives and the parameter value included in the received scheduled recording setting information includes a parameter value that the PVR 10 cannot accept, the PVR 10 changes the unacceptable parameter value to an acceptable parameter value and changes the parameter value. Even if the combination of the parameters and parameter values of the scheduled recording setting information set by the user is unacceptable because the subsequent scheduled recording setting information is sent back to the PC 2, the user can make a reservation many times. Scheduled recording without having to redo the recording settings and forcing so-called cut-and-try It can be set efficiently and accurately.

  The present invention is applied to a purpose of performing reservation recording using a reservation recording setting device and a plurality of reservation recording devices connected to each other via a home network. In addition, if it is used for recorded content information (metadata) instead of a reserved recording entry, it can also be applied to a purpose of displaying the interrelated information of recorded content in an integrated manner.
