  As described above in detail, according to the present invention, even if the information recording apparatus or information processing apparatus connected to the network is in a power standby state, the set recording reservation is updated to the latest state. Thus, a recording reservation system, a recording reservation setting device, and an information recording device can be obtained.

  Embodiments of the present invention will be described below. In addition, the same code | symbol is used for the same element and the overlapping description is abbreviate | omitted.

  FIG. 1 is a block diagram showing a configuration of a home network 1 including an HDD recorder 11 as a recording reservation setting device and HDD recorders 12 and 13 as information recording devices according to an embodiment of the present invention.

  The home network 1 includes a network 2 such as Ethernet (registered trademark) or a wireless LAN, and is configured using a technology that can use a band necessary for transmission of video data. HDD recorders 11, 12, and 13 are connected to the network 2.

  As will be described in detail later, each of the HDD recorders 11, 12, and 13 includes an HDD and a DVD drive, receives a broadcast wave, and receives an HDD or an optical disk D (for example, DVD-RAM) not shown in FIG. And DVD-R) have a function as an information recording device capable of recording and recording digital data such as MPEG (Moving Picture Image Coding Experts Group) -2 format video data and audio data. Yes. It is also possible to read recorded digital data in the MPEG-2 format and reproduce video data and audio data.

  Connected to the HDD recorders 11, 12, and 13 are televisions 14, 15, and 16 as display devices that display video using the reproduced video data. The televisions 14, 15, and 16 can display playback images and operation screens by the HDD recorder. The televisions 14, 15 and 16 can receive broadcast waves and view video content, and acquire video data and audio data reproduced from digital data read by the HDD recorders 11, 12 and 13 from the HDD or optical disk. Thus, it has a function of reproducing video and audio.

  FIG. 2 is a block diagram showing the internal configuration of the HDD recorder 11 (not shown, but the internal configurations of the HDD recorders 12 and 13 are the same as the internal configuration of the HDD recorder 11, and the HDD recorders 12 and 13 are HDD recorders). 11 has the same function). A broadcast wave signal received by an antenna (not shown) is input to the TV tuner 21.

  The TV tuner 21 demodulates the input signal and outputs an analog video signal. This analog video signal is quantized by an ADC (Analog To Digital Converter) 22 with a sampling frequency of 13.5 MHz and a quantization bit number of 8 bits, for example. Similarly, the analog audio signal is also quantized by the ADC 22 with, for example, a sampling frequency of 48 kHz and a quantization bit number of 16 bits.

  The digital video signal and digital audio signal output from the ADC 22 are input to the encoder 23. The encoder 23 compresses the input digital video signal based on the MPEG-2 standard, and outputs the compressed video data. The digital audio signal is also compressed based on, for example, the AC (Audio Compression) -3 standard, converted into a compressed digital audio signal, and output.

  The encoder 23 performs signal processing so that the compressed digital video signal and digital audio signal have a format suitable for recording and outputs the signal to the data processor 24. The video data and audio data encoded by the encoder 23 and the management information created by the controller 32 are transferred via the data processor 24 to an HDD 25 (to be described later) or an optical disk D such as a DVD-RAM inserted in the DVD drive 26. To be recorded.

  Signals (video data and audio data) recorded on the HDD 25 and the optical disk D inserted into the DVD drive 26 are output to the decoder 27 via the data processor 24. The decoder 27 has a function of separating a video signal and an audio signal from an input signal and decoding them. The video signal output from the decoder 27 is input to the video mixer 28. The video mixer 28 combines the input video signal with text data and image data while using the frame memory 29 as a buffer. The output of the video mixer 28 is converted to an analog signal by a DAC 30 (Digital To Analog Converter) and then output to the outside. Similarly, the audio signal output from the decoder 27 is converted to an analog signal by the DAC 31 and then output to the outside.

  The controller 32 has an MPU (Micro Processing Unit), ROM and RAM. In the ROM, a control program and a program executed by the MPU are written. The RAM can provide a work area necessary for executing the program by the MPU. The controller 32 controls the above-described modules in accordance with a control program stored in the ROM, and supervises a set operation such as recording or reproduction.

  Further, the controller 32 receives operation information of the remote controller 40 operated by the user via an infrared light receiving unit 34 described later, and controls the operation according to the received information. Furthermore, the controller 32 controls the operation of a network interface (network I / F) 33 that performs communication with other devices (for example, the HDD recorder 12) connected to the network 2. Furthermore, the controller 32 provides a library management function.

  The controller 32 is used for data recording (here, recording is assumed) by the HDD 25 or the DVD drive 26, and information set in advance prior to the data recording (recording) (hereinafter referred to as "recording reservation information"). The execution of the scheduled recording is controlled on the basis of the details described later.

  Further, the controller 32 stores and holds such recording reservation information in a recording reservation list described later. The controller 32 monitors the current time, and controls the recording operation to start at the recording start time of any recording reservation information stored in the recording reservation list.

  That is, the controller 32 selects a channel designated by the channel number of the recording reservation information when the recording start time comes, and operates the encoder 23 according to the recording mode to execute recording. Further, the controller 32 monitors the current time even during the execution of the recording, stops the recording operation when the recording end time is reached, and stores the signals (video signal and audio signal) recorded by the recording operation. When the recording is completed, the controller 32 generates title information described later using program information and recording reservation information acquired from the program information list described later, and adds the generated title information to the title list.

  The network I / F 33 is used to send and receive messages to and from other information recording devices (HDD recorders 12 and 13) connected to the home network 1. The controller 32 interprets a message received via the network I / F 33, generates a message to be transmitted to another information recording device, and transmits the message via the network I / F 33.

  The network I / F 33 is powered even while the HDD recorder 11 is in a power standby state.

  The HDD recorder 11 has a Wake On LAN function. That is, when the network I / F 33 receives a Wake On LAN startup message in a predetermined format, the network I / F 33 sends a startup signal to a power control module 35 to be described later. 35 turns on (starts up) the power of the HDD recorder 11 to bring it into a power-on state.

  The infrared light receiver 34 receives operation information of the remote controller 40. When receiving the operation information of the remote controller 40, the infrared light receiver 34 inputs the operation information to the controller 32. The controller 32 interprets the operation information and controls the operation according to the operation state at that time.

  The power supply control module 35 also puts the HDD recorder 11 in a power-on state even when an activation signal based on a power-on operation of the remote controller 40 is input from the infrared light receiver 34.

  The HDD recorder 11 holds the following data regarding the recording reservation. That is, the HDD recorder 11 has a title list that holds information of recorded titles, a recording reservation list that holds recording reservation information of a set recording reservation, a program information list that holds program information to be broadcast, They are an other apparatus recording reservation list and a moved recording reservation list which hold recording reservation information acquired from other information recording apparatuses (for example, HDD recorder 12). These data are stored in the HDD 25 so that they are not erased even when the power of the HDD recorder 11 is turned off.

  In the title list, title information representing title attribute data is recorded for each title recorded on a recording medium such as the HDD 25 or the optical disc D. The title information includes a recording start time when recording is started, a recording end time when recording is ended, a channel number indicating a channel where recording is performed, a title information of a recorded program, a recording mode indicating a bit rate of the recorded title, and the like. .

  The recording reservation list holds recording reservation information necessary for controlling the set recording reservation. The recording reservation information includes information such as a channel number indicating a channel for recording, a recording start time for starting recording, a recording end time for ending recording, a recording mode indicating a bit rate set in the encoder 23 at the time of recording, and the like. included.

  For example, in the case of digital broadcasting, information necessary for recording is recording reservation information, such as specifying an event ID instead of the recording start time and the recording end time. The recording mode is information such as the type of codec used for recording and the bit rate. The recording reservation information includes a reservation ID having a unique value for each recording reservation. Note that the recording reservation information is not information directly necessary for recording, but information such as program genre information and title names can be included.

  The program information list holds program information related to programs that are currently being broadcast or are scheduled to be broadcast. The program information includes a channel number indicating a channel, a program start time at which the program starts, a program end time at which the program ends, and program title information. In the case of analog broadcasting, the program information is data distributed by ADAMS (TV-Asahi Data and Multimedia Service) -EPG (Electronic Program Guide) superimposed on the broadcast wave, and in the case of digital broadcast, it is superimposed on the broadcast wave. It is acquired from SI (Service Information) information. It can also be acquired from a server (not shown) that is connected to the Internet and publishes program information. The program information list is updated at a predetermined interval such as once a day.

  The other device recording reservation list holds the recording reservation information of the recording reservation set in the other information recording device acquired from the other information recording device (for example, HDD recorder 12) connected to the home network 1. And has a function as recording reservation information storage means.

  In the moved recording reservation list, the setting is changed so that the recording reservation is executed in another device (for example, HDD recorder 12) among the recording reservations originally set in the own device (HDD recorder 11) (for example, This is a list holding recording reservation information (moved from the HDD recorder 11 to the HDD recorder 12).

  The controller 32 manages recording reservations set in other information recording apparatuses using this moved recording reservation list, and has a function as recording reservation management means.

(Network recording reservation service)
The controller 32 executes a network recording reservation service function that makes recording reservation information available to other information recording devices connected to the home network 1 and enables setting of recording reservations from other information recording devices. To do. In order to realize such a function, the controller 32 communicates with another information recording device (for example, the HDD recorder 12) connected to the network 2 using the UPnP (Universal Plug And Play) standard. However, the above functions can also be realized using other similar protocols.

  Here, UPnP will be described. UPnP makes troublesome settings for discovery and operation of devices (information recording devices, printers, scanners, etc.) connected to a network in which operations based on TCP / IP (Transmission Control Protocol / Internet Protocol) are performed. The goal is to make this possible without any problems.

  In UPnP, a device that provides some function to a device connected to a network is called a “device”, and a function provided by the “device” is called a “service”. An apparatus that uses and controls a “service” provided by a “device” is called a “control point”. These “device” and “control point” are conceptual models for defining the protocol. Therefore, an actual apparatus (for example, HDD recorder 11, 12, 13) may have both a function as “device” and a function as “control point”.

  An SSDP (Simple Service Discovery Protocol) is used to discover the information recording device and the “service” provided by the information recording device. By using SSDP, “device” can notify that “device” or “service” exists on the network, and “control point” can search for a desired “device”. From the device discovered by SSDP, the attribute information of the information recording device described in XML (Extensible Markup Language) format called Device Description can be acquired.

  The Device Description describes an UDN (Unique Device Name) that is an identifier for uniquely identifying a device, a FriendlyName used for display, a list of provided “services”, and the like. Similarly, for “service”, data in XML format called “Serivce Description” can be acquired, and operations that can be executed are described. The operation described in Service Description is called using SOAP (Simple Object Access Protocol).

  When the status of the service is changed, a message can be sent to the control point by GENA (Generic Event Notification Architecture) to notify the fact.

  Operations that can be executed by other information recording devices (for example, the HDD recorder 11) on an information recording device (for example, the HDD recorder 12) that provides the network recording reservation service include a recording reservation acquisition request, a recording reservation setting request, These are a recording reservation update request, a recording reservation deletion request, and a free space confirmation request (all will be described later).

  When the HDD recorder 11 provides a network recording reservation service as a “device”, the controller 32 records (transfers) a recording transmitted from another information recording device (for example, the HDD recorder 12) connected to the network 2. A network recording reservation service is executed to receive reservation information. The network recording reservation service is realized as an SRS (Scheduled Recording Service) which is the “service” of UPnP described above.

  In addition, the controller 32 executes a network recording reservation service and also functions as a “control point” for the network recording reservation service that operates on other information recording devices. In this case, the controller 32 transmits a recording reservation acquisition request, a recording reservation setting request, and the like to a network recording reservation service that operates on another information recording apparatus. For example, by setting a recording reservation setting request from the HDD recorder 11 to the HDD recorder 12, the recording reservation can be set in the HDD recorder 12. This recording reservation setting request includes the above-described recording reservation information. In this case, the controller 32 operates as a recording reservation setting request means.

  When the HDD recorder 11 operates as a “device” that provides a network recording reservation service, the following operation is performed.

  First, when the HDD recorder 11 receives a recording reservation setting request from another information recording device (HDD recorder 12), the controller 32 analyzes the recording reservation information included in the received recording reservation setting request and can execute the recording. It is determined whether or not it is a reservation, and if it is an executable recording reservation, an operation as a recording reservation setting means is performed, and the recording reservation information is added to the recording reservation list to set the recording reservation.

  Here, the executable recording reservation means that the channel specified in the recording reservation information can be received and the recording mode is supported. Even in such a case, there may be a case where the recording cannot be executed because a time overlapping with the already set recording reservation is specified. Here, however, such a case is processed as an executable recording reservation. If it is not an executable recording reservation, an error response is returned.

  When the HDD recorder 11 receives the recording reservation acquisition request, the controller 32 acquires the recording reservation information stored in the recording reservation list, and transmits the acquired recording reservation information as a response.

  Further, when the HDD recorder 11 receives the recording reservation update request, the controller 32 analyzes the reservation ID and the recording reservation information included in the received recording reservation update request, and designates the reservation ID specified in the recording reservation list. And the recording reservation information having the same reservation ID are updated with the received recording reservation information. When the recording reservation information having the specified reservation ID does not exist in the recording reservation list, an error response is returned.

  Furthermore, when the HDD recorder 11 receives a recording reservation deletion request, the controller 32 analyzes the reservation ID included in the received recording reservation deletion request and performs an operation as a recording reservation deletion unit. The recording reservation information having the specified reservation ID is deleted. When the recording reservation information having the specified reservation ID does not exist in the recording reservation list, an error response is returned.

  When the HDD recorder 11 receives the free space confirmation request, the controller 32 calculates the free space from the recording capacity of the HDD 25 and the data size of the video data already recorded, and transmits the obtained free space as a response. To do.

  In the network recording reservation service, when the set recording reservation is changed, a recording reservation information update notification for notifying that the recording reservation information has been changed can be transmitted using GENA.

(Move recording reservation)
The HDD recorder 11 can move the recording reservation set in the above-described recording reservation list so as to perform recording with another information recording device (for example, the HDD recorder 12). The recording reservation is moved when a new recording reservation is set and the recording reservation cannot be executed in conflict with the already set recording reservation. Recording reservation conflicts are due to overlapping recording reservation times (part or all from the recording start time to the recording end time) for other channels of the same tuner, or exceeding the maximum number of recording reservations that can be executed simultaneously. Occurs when is set.

  When the controller 32 detects that there is a recording reservation conflict for the set recording reservation, the controller 32 performs the following device search. This apparatus search is a process of checking the recording reservation information held in the other apparatus recording reservation list for each apparatus and searching for an information recording apparatus in which no recording reservation conflict occurs.

  When the controller 32 finds an information recording apparatus that does not cause a recording reservation conflict by the apparatus search, it transmits a recording reservation setting request to the found information recording apparatus.

  If the recording reservation setting request is successful, the controller 32 deletes the recording reservation information of the recording reservation that has been in conflict from the recording reservation list, and moves the recording reservation information and the recording reservation information of the information recording apparatus to which the recording reservation has been moved. Add to list. In this way, the controller 32 manages the set recording reservation. When the recording reservation setting request is unsuccessful, the same procedure is repeated for another information recording apparatus that does not cause a recording reservation conflict.

(Update recording reservation list)
The controller 32 updates the recording reservation list when a new recording reservation is set, when an already set recording reservation is updated, when a recording reservation setting request is executed, or the like.

  In addition, when the recording reservation list is updated, the controller 32 updates the recording reservation list so that other information recording devices (for example, the HDD recorder 12) connected to the home network 1 can update the other recording reservation list. A Wake On LAN startup message is sent to other registered information recording devices. The device list is a list of other information recording devices connected to the network 2.

(Update recording reservation list of other devices)
Next, the update operation of the other apparatus recording reservation list will be described by taking as an example a case where the recording reservation set in the HDD recorder 11 is moved to the HDD recorder 12 and then the HDD recorder 11 is in a power standby state. In this case, assuming that the HDD recorder 11 operates as a recording reservation setting device and the HDD recorder 12 operates as an information recording device, the HDD recorder 11 and the HDD recorder 12 constitute a recording reservation system.

  When the HDD recorder 11 is started by a start request from another information recording device (in this embodiment, a start request by Wake On LAN is assumed), the other device recording reservation is performed according to the flowchart shown in FIG. Update the list.

  As shown in FIG. 3, when the HDD recorder 11 is activated, the controller 32 performs an activation process (S1), and acquires an activation factor from the power supply control module 35 in the subsequent S2 (S2).

  Then, the controller 32 determines whether or not the activation factor is due to the activation request from another information recording device, that is, the reception of the activation message of Wake On LAN (S3).

  If the activation factor is due to the reception of the activation message of Wake On LAN, the process proceeds to S4. Otherwise, the update process of the other apparatus recording reservation list is terminated. When proceeding to S4, the controller 32 performs an operation as an acquisition means, and transmits a recording reservation acquisition request to the information recording apparatus (HDD recorder 12) executing the SRS connected to the home network 1, Receives the response and obtains recording reservation information. In addition, when the recording reservation information is acquired, the controller 32 performs an operation as an updating unit, and updates the other apparatus recording reservation list using the acquired recording reservation information (S5).

  Although not shown, the HDD recorder 11 also updates the other device recording reservation list when receiving the recording reservation information update notification from the SRS. In this case, the recording reservation information is acquired from the apparatus that has received the recording reservation information update notification, and the other apparatus recording reservation list is updated.

  Then, when the controller 32 updates the other apparatus recording reservation list, whether or not there is a recording reservation conflict in the destination information recording apparatus for each of the recording reservations registered in the moved recording reservation list. Is determined (S6).

  If the controller 32 determines that a conflict has occurred, the controller 32 proceeds to S7 and performs the above-described device search. If not, the other device recording reservation list update process ends.

  In S7, the controller 32 checks the recording reservation information held in the other device recording reservation list for each information recording device, and searches for an information recording device that does not cause a recording reservation conflict (S7).

  Next, the controller 32 determines whether or not an information recording device that does not cause a recording reservation conflict has been found (S8).

  When the controller 32 finds an information recording device (for example, HDD recorder 13) that does not cause a recording reservation conflict, the process proceeds to S9. When such an information recording device is not found, the other device recording reservation list update process ends. .

  When the controller 32 proceeds to S9, the controller 32 operates as a recording reservation resetting control means, and again makes a recording reservation setting request to the information recording device (for example, the HDD recorder 13) based on the updated recording reservation information. Send.

  Subsequently, the controller 32 performs an operation as a determination unit, and determines whether or not the recording reservation setting request (also referred to as a reset request) performed in S9 is successful (S10). If it is determined that the reset request is successful, the process proceeds to S11. If the reset request is not successful, the other device recording reservation list update process is terminated.

  When the controller 32 proceeds to S11, the controller 32 operates as a transmission control means, and transmits a recording reservation deletion request to the network I / F 33 to the information recording apparatus (for example, the HDD recorder 12) in which the recording reservation conflict has occurred. (S11).

  Further, the controller 32 continues to the information recording apparatus (for example, the HDD recorder 13) that newly sets a recording reservation (information for which a reset request has been made) for the information of the movement destination apparatus registered in the moved recording reservation list in S12. After updating and executing S12, the update processing of the other apparatus recording reservation list is terminated.

  Although not shown, when the recording reservation process registered in the moved recording reservation list is completed, the moving process is performed if possible even for the recording reservation in which a conflict in the recording reservation list has occurred. Do.

(Contents of startup message transmission control processing)
In response to the HDD recorder 11 updating the other device recording reservation list, the HDD recorder 12 executes the startup message transmission control process according to the flowchart shown in FIG.

  The HDD recorder 12 determines whether or not the recording reservation list has been updated by the controller 32 (S21). If the controller 32 determines that the recording reservation list has been updated, the process proceeds to S22. If not, the startup message transmission control process ends.

  Next, when the controller 32 proceeds to S22, it performs an operation as a transmission control means, and controls the network I / F 33 to transmit a Wake On LAN activation message. When the network I / F 33 transmits a Wake On LAN activation message to the HDD recorder 11 in S22, the activation message transmission control process ends.

  As described above, according to the present invention, when the recording reservation is set from the HDD recorder 11 to the HDD recorder 12 or the recording reservation is moved, the HDD recorder 11 is in the power standby state. Even if the recording reservation list is updated by the HDD recorder 12, the HDD recorder 11 is activated in response to the activation request from the HDD recorder 12, acquires the recording reservation information from the HDD recorder 12, and updates the other apparatus recording reservation list. .

  Therefore, in the home network 1, the recording reservation set in the HDD recorders 11 and 12 connected to the network 2 can be maintained in the latest state.

  In addition, when a recording reservation conflict occurs due to the update of the recording reservation list in the HDD recorder 12, another information recording apparatus (for example, HDD) capable of recording even when the recording reservation set from the HDD recorder 11 cannot be executed. If the recorder 12) can be found, the HDD recorder 11 makes a reset request to the HDD recorder 13 and moves the recording reservation. Therefore, it is possible to avoid a conflict in recording reservation, and the recording reservation is performed as set using the HDD recorder 11 as the recording reservation setting device.

  Furthermore, since the HDD recorder 11 has a recording reservation list of other devices that records the recording reservation information acquired from the HDD recorder 12, the recording reservation information set in the information recording device in the power standby state is displayed. You can refer to it.

  In addition, the HDD recorder 12 starts the HDD recorder 11 by performing an operation in which the controller 32 transmits an activation message of Wake On LAN to the HDD recorder 11 when the recording reservation list is updated. 11 can issue a recording reservation information acquisition request to the HDD recorder 12 to acquire the recording reservation information from the HDD recorder 12 and update the other apparatus recording reservation list.

  Note that the HDD recorders 11, 12, and 13 may be devices that incorporate an HDD but do not incorporate a DVD drive as means for recording information. Further, instead of the HDD recorders 11, 12, and 13, a DVD recorder that incorporates a DVD drive but does not incorporate an HDD may be used.

  Moreover, although the HDD recorder 11 as a recording reservation setting device has an information recording unit, the recording reservation setting device may be a device that does not have an information recording unit.

  In the above embodiment, the case where reserved recording is performed has been described as an example. However, the present invention can also be applied to a case where recording of audio information is reserved (reserved recording).

  The case where the HDD recorder 11 receives a Wake On LAN startup message as a startup request from another information recording device has been described as an example, but data different from the Wake On LAN startup message has been received as a startup request.
