Description

  The present invention relates to an information recording device and an information recording communication device having a function for simplifying handling related to password input.

  In recent years, home networks have been built. The home network is a home television, HDD recorder (HDD: information recording device with a built-in hard disk drive), DVD recorder (DVD: DVD) via a network such as Ethernet (registered trademark) or wireless LAN (Local Area Network). An apparatus having a video and audio reproduction or recording function (such as an information recording apparatus having a digital data recording function for a digital versatile disk) is connected to each other in accordance with technical specifications such as UPnP. In the home network, for example, video content recorded on the HDD of the HDD recorder is played back on a TV connected via the network, or video content recorded on the HDD is copied (dubbed) to the HDD of another HDD recorder via the network. Can be operated.

By the way, the HDD recorder can store the data of a large number of programs as compared with the video tape recorder, but if the data of the program that is no longer necessary is not deleted from the HDD, the HDD becomes full. There will be insufficient space available. Related to such a case, there has conventionally been a technique related to performing recording in a distributed manner by recording devices distributed to a network by transferring a recording command to another device (for example, Patent Document 1). ).
JP-A-8-56352

  By the way, when receiving broadcast waves of digital broadcasting to record TV video content or radio sound data, it may be necessary to enter a password when recording or recording reservations are made. is there. For example, it is a case where video content whose viewing age is limited or video content based on PPV (Pay Per View) charged according to the number of times data is downloaded is recorded. Therefore, even when information (reservation information) necessary for recording or recording reservation is transferred as in the prior art and recording or recording is performed, it is necessary to transfer the password together with the reservation information. However, a normal password is set for each information recording device. Therefore, when the reservation information is transferred, it is necessary to transfer the password set in the transfer destination information recording apparatus together with the reservation information.

However, as disclosed in Patent Document 1, for example, HD (Hard Disk
The following problems arise when recording is performed in a distributed manner, such as when there is a lack of free space) or when the recording time zones overlap. That is, at the time when the reservation information is generated by the information recording device, the information recording device that performs the reserved recording is not necessarily determined based on the reservation information (the recording may be performed by the information recording device that generated the reservation information). If the user cannot input the password set for the information recording device that performs the recording (information recording that the input password records) Occurs if the device is not supported). Further, even in a situation where a password can be entered, there is a problem that it is troublesome for the user to use a different password for each information recording device.

  Accordingly, the present invention has been made to solve the above problems, and an information recording apparatus and information recording communication having a function for simplifying the handling of password input when recording and recording are reserved and performed. An object is to provide an apparatus.

Information recording means for recording video data or audio data to be recorded, and reservation setting means for performing reservation setting for causing the information recording means to record video data or audio data based on reservation information received by the communication means, When the communication means receives the reservation information, the reservation setting means sets the reservation if the password required for viewing the video or audio obtained by the tuner has been confirmed, and the password is not confirmed Is characterized by an information recording device that does not perform reservation setting.

  Further, the present invention records communication means for performing data communication with other information recording apparatuses via a network, a tuner for selecting and receiving broadcast waves, and video data or audio data obtained by receiving with the tuner. Information recording means, reservation information generating means for generating reservation information set in advance before video data or audio data is recorded by another information recording device, and viewing of video or audio received by the tuner A password determination unit that determines whether the password required for the password is correct, and based on the determination result of the password determination unit, the communication unit notifies the other information recording device whether or not the password has been confirmed. An information recording apparatus having a control means is provided.

  Further, the present invention provides communication means for performing data communication with an information recording device via a network, a tuner for selecting and receiving a broadcast wave, and presetting before video data or audio data is recorded by the information recording device. Based on the determination result of the reservation information generation means for generating the reservation information to be performed, the password determination means for determining the correctness of the password required for viewing the video or audio obtained by receiving by the tuner, and the password determination means An information recording communication device having notification control means for notifying the information recording device from the communication means whether or not the password has been confirmed is provided.

  As described above in detail, according to the present invention, it is possible to obtain an information recording apparatus and an information recording communication apparatus having a function for simplifying the handling of password input when recording and recording are reserved and performed. .

  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 provided with HDD recorders 11 and 12 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. The network 2 is connected to HDD recorders 11 and 12 and a television 13. As will be described in detail later, the HDD recorders 11 and 12 both have a built-in HDD and a DVD drive, receive broadcast waves, and in the MPEG (Moving Picture Image Coding Experts Group) -2 format HDD or optical disc D ( For example, digital data can be recorded on a DVD-RAM, DVD-R, etc., and recording and recording can be performed. It is also possible to reproduce the recorded MPEG2 format digital data.

  Television recorders 14 and 15 serving as monitors for displaying video output are connected to the HDD recorders 11 and 12, respectively. The televisions 14 and 15 can display playback images and operation screens by the HDD recorder. The television 13 can receive broadcast waves and view video content, and has a function of acquiring video data and audio data reproduced by the HDD recorders 11 and 12 from the HDD or optical disc and reproducing video and audio. is doing.

  FIG. 2 is a block diagram showing the internal configuration of the HDD recorder 11 (not shown, but the internal configuration of the HDD recorder 12 is the same as the internal configuration of the HDD recorder 11, and the HDD recorder 12 is the same as the HDD recorder 11). Has a 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. The 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, converts it into a compressed digital video signal, and outputs it. 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. Information encoded by the encoder 23 and management information created by the controller 32 are recorded on an optical disk D such as an HDD 25 (described later) or a DVD-RAM inserted in the DVD drive 26 via the data processor 24.

  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 includes an MPU (Micro Processing Unit), a ROM, and a 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 controls setting operations such as recording and playback. The controller 32 receives operation information of a remote controller (not shown) operated by the user via an infrared light receiving unit (not shown), 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 information recording (here, recording is assumed) by the HDD 25 or the DVD drive 26, and information set in advance prior to recording (recording) the information (hereinafter referred to as "reserved recording information"). The execution of the scheduled recording is controlled based on the above. Here, the reserved recording information includes information such as a channel number, recording start time, recording end time, and recording mode. For example, in the case of digital broadcasting, information necessary for recording is reserved recording information such that an event ID is designated 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 reserved recording information is not information necessary for recording directly, but can include information such as program genre information and title names.

  Further, the controller 32 holds a reserved recording information table in which reserved recording information is recorded. The scheduled recording information table is stored in the ROM or RAM (or HDD).

  Then, the controller 32 monitors the current time and executes the recording operation when the recording start time of any one of the scheduled recording information recorded in the scheduled recording information table is reached. When the recording start time comes, the channel designated by the channel number of the reserved recording information is selected, and recording is performed by controlling the encoder 23 according to the recording mode. Further, the controller 32 monitors the current time during 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.

  Incidentally, the controller 32 uses the UPnP (Universal Plug and Play) standard in order to communicate with other devices (for example, the HDD recorder 12) connected to the network 2.

  Here, UPnP will be described. UPnP makes troublesome settings for discovery and operation of devices (information recording devices, printers, scanners, etc.) connected to the network in an operation based on TCP / IP (Transmission Control Protocol / Internet Protocol). 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 recorders 11 and 12) may have both a function as a “device” and a function as a “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 obtained. Device Description describes an UDN (Unique Device Name) that is an identifier for uniquely identifying a device, a friendly name used for display, a list of “services” to be provided, and the like. Similarly, with regard to “service”, XML format data called “Service Description” can be acquired, and operations that can be executed are described. The operations described in the Service Description are called using SOAP (Simple Object Access Protocol).

  The controller 32 operates the network recording reservation service in order to receive reservation recording information transmitted (transferred) from another device (for example, the HDD recorder 12) connected to the network 2. The network recording reservation service is realized as a UPnP “service”. The “control point” can make a recording reservation by transmitting a recording reservation request to a device that provides a network recording reservation service. The recording reservation request includes reservation recording information. When the device that provides the network recording reservation service (ie, “device”) receives the recording reservation request, it analyzes the reserved recording information included in the received recording reservation request and determines whether or not the recording reservation can be set. Make a decision. Further, the “device” notifies the result of the determination to the “control point”. If the recording reservation can be set, the “device” executes the same process as the normal recording reservation (when the recording reservation is directly performed by the “device”).

  FIG. 3 is a flowchart showing an operation procedure of a reservation setting process performed when an information recording apparatus (that is, “device”) that provides a network recording reservation service receives a recording reservation request via the network 2. In the following description, it is assumed that the HDD recorder 11 is a “device” in UPnP and the HDD recorder 12 is a “control point”. Therefore, in the following description, as shown in FIG. 6, the HDD recorder 12 presents scheduled recording information by transmitting a recording reservation request RQ to be described later to the HDD recorder 11, and the HDD recorder correspondingly It is assumed that a recording reservation response RS (described later) is transmitted (presented) from 11 to the HDD recorder 12 (reply of failure information described later). When the reservation setting process is performed according to the flowchart of FIG. 3, the controller 32 performs operations as a reservation setting control unit, a reservation impossible information presenting unit, and a confirmation determination control unit.

  In the HDD recorder 11, the controller 32 starts execution of a program for providing the network recording reservation service, proceeds to step 1, and analyzes the received reservation recording information. Subsequently, the controller 32 advances the process to step 2 to determine whether or not the program (reserved program) specified by the reserved recording information can be recorded (received). If the recording is for a program that cannot be received, the controller 32 advances the processing to step 9 and responds to the HDD recorder 12 that is the “control point” with information on the response (hereinafter referred to as “failure information”). ) If the program is a receivable program, the controller 32 proceeds to step 3 and acquires program information for the program. Here, the acquired program information is included in, for example, SI information (Service Information) superimposed on the broadcast wave.

  Next, the controller 32 advances the process to step 4 to perform an operation as a program determination unit, and determines whether or not the reserved program is a password request program requiring input of a password based on the acquired program information. The password needs to be input when, for example, a viewing age limit is applied. If the controller 32 determines that the program requires a password, the process proceeds to step 5; otherwise, the process proceeds to step 6 without executing step 5. When the process proceeds to step 5, the controller 32 performs an operation as a confirmation determination unit, and confirms whether or not the password is confirmed by the scheduled recording information transmission source device (that is, the HDD recorder 12 in this case) (password). Is confirmed). In this case, the controller 32 refers to a password confirmation flag, which will be described later, included in the scheduled recording information, and determines whether or not the password has been confirmed.

  If the controller 32 determines that the password has not been confirmed in the transmission source device (the password has not been confirmed), the controller 32 advances the process to step 9 to send failure information to the HDD recorder 12 that is the “control point”. (This failure information has a meaning as reservation impossible information indicating that reservation cannot be set). Further, when the password is confirmed in the transmission source device, the controller 32 advances the process to step 6 to determine whether or not a new recording reservation can be set in relation to the existing recording reservation (accepting the recording reservation). If it can be set, the process proceeds to step 7; otherwise, the process proceeds to step 9 to return failure information.

  Further, when the process proceeds to step 7, the controller 32 performs an operation as a reservation setting unit, and sets a new recording reservation based on the reserved recording information determined to be confirmed (necessary of the reserved recording information). Information is registered in the scheduled recording information table), and the process proceeds to the next step 8 to obtain response information indicating success (hereinafter referred to as “success information”, reserved information indicating that the reservation setting has been performed. The network reservation I / F 33 is actuated and sent back to the “HDD recorder 12” as the control point for presentation (the recording reservation response RS is sent by the processing of the above steps 8 or 9). )

  Next, the operation procedure of the HDD recorder 12 that makes a recording reservation request to the HDD recorder 11 that provides the network recording reservation service will be described with reference to the flowchart shown in FIG. Note that FIG. 4 includes the operation of the HDD recorder 12 and the operation of the user who operates the HDD recorder 12.

  First, when a user intends to perform scheduled recording, the user needs to input scheduled recording information to the HDD recorder 12. The reservation recording information input in step 11 is performed, for example, when the user designates a program by remote control operation while referring to a list of programs scheduled to be broadcast thereafter displayed on the television 15. When a program is designated, information such as a reception channel, a recording start time, and a recording end time is determined. Therefore, the HDD recorder 12 displays such information on the television 15.

  Subsequently, the process proceeds to step 12, and the HDD recorder 12 displays a screen (recording mode input screen) on which the recording mode can be input on the television 15. When this recording mode input screen is displayed, necessary information such as the recording mode is entered, and when the user performs an operation to confirm the information entered, the controller operates as a reservation information generation means, Generate recording information. Thereby, the input of the scheduled recording information is completed. When the input of the scheduled recording information is completed, the controller of the HDD recorder 12 advances the process to step 13 to acquire the attribute information of the designated program. The attribute information is acquired from SI information or the like superimposed on the broadcast wave.

  Then, the controller of the HDD recorder 12 advances the processing to step 14 to perform the operation as the program determination means, extracts the viewing age restriction information included in the program attribute information, and sets the viewing age setting set in the HDD recorder 12 Compare with information. Based on this comparison, the controller of the HDD recorder 12 determines whether or not the reserved program is a password request program requiring password input. When the controller determines that the program is a password request program, the process proceeds to step 15 to request the user to input a password. Otherwise, the process proceeds to step 17 without executing steps 15 and 16. .

  The controller advances the process to step 16 following step 15 to perform an operation as a password determination unit, and whether or not the input password matches the preset password, that is, the input password is correct. It is determined whether or not it is a password (password correct / incorrect). If it is determined that the password is correct, the process proceeds to step 17 to accept the scheduled recording information, updates the scheduled recording information table and ends the process. If not, the process proceeds to step 18. Then, the recording reservation failure is notified to the user and the process is terminated. In this case, the controller performs an operation as a determination control unit.

  Next, an operation procedure for transferring the reserved recording information once input to another device will be described with reference to the flowchart of FIG. The device to which the scheduled recording information is transferred is selected from the devices detected by the “control point” that the network recording reservation service is operating according to the UPnP protocol. As described above, in this embodiment, since the network recording reservation service is operating in the HDD recorder 11, the HDD recorder 12 that is the “control point” selects the HDD recorder 11 that is the “service”, and the HDD recorder 11. The scheduled recording information is transmitted to the recording reservation request.

  When the process starts, the HDD recorder 12 advances the process to step 21 shown in FIG. 5 to select a device to which the scheduled recording information is to be transferred from the devices connected to the network 2 (in this case) HDD recorder 11 is selected).

  Subsequently, the controller of the HDD recorder 12 proceeds to step 22 to determine whether or not the password has been confirmed. When it is determined that the password has been confirmed, the process proceeds to step 23; The process proceeds to 24. In step 23, data indicating confirmation (for example, “1”) is set in a password confirmation flag indicating whether or not the password has been confirmed. In step 24, the password confirmation flag is cleared. This password confirmation flag is included in the scheduled recording information and transmitted in the subsequent step 25 by the network I / F 33. By doing so, the controller of the HDD recorder 12 performs an operation as a notification control unit, and controls to notify the HDD recorder 11 whether or not the password has been confirmed.

  When the processing proceeds to step 25 following steps 23 and 34, the controller of the HDD recorder 12 controls the operation of the network I / F to generate a reservation recording request RQ including reservation recording information as shown in FIG. Send. Thereafter, when the process proceeds to step 25, the recording reservation response RS is received and the response message included therein is referred to. In the following step 27, it is determined whether or not the reserved recording is successful. Executes step 28; otherwise, the process ends without executing step 28. When the success information is returned, the controller of the HDD recorder 12 advances the process to step 28 to delete the corresponding scheduled recording information from the scheduled recording information table.

  As described above, when the HDD recorder 11 performs reserved recording according to the reserved recording information transmitted from the outside (HDD recorder 12) via the network 2, it is determined whether or not the password is confirmed in the reserved recording information. Since the password confirmation flag shown is added, if the password confirmation flag has been confirmed with reference to the password confirmation flag, the scheduled recording can be performed even if the password is required or no new password is entered. Therefore, the user only has to input a password corresponding to the device for setting the reserved recording (the HDD recorder 12 in the above embodiment) when performing the input operation of the reserved recording information by inputting the program information. It is not necessary to input the password of another device on the network 2 (in the above embodiment, the HDD recorder 11), and the input operation can be performed without worrying about whether the actual recording is performed by another device. For this reason, even when the recording apparatus is not fixed, the user can surely input the password, so the HDD recorder 11 can easily handle the password input. Further, since it is not necessary to use the password input by the HDD recorders 11 and 12, it is possible to eliminate the complexity related to the password input and to further simplify the handling related to the password input. In addition, since handling regarding password input is simplified, the degree of freedom in transferring reserved recording information for the purpose of distributing the recording load is improved.

  Furthermore, since the HDD recorder 11 does not set the recording reservation when the password is not confirmed, the HDD recorder 11 is not erroneously recorded even though the password is required. Further, when the password has not been confirmed, information indicating that the recording reservation cannot be performed (the failure information described above) is sent back from the HDD recorder 11 to the HDD recorder 12, so that the recording reservation cannot be performed. The user can also check with the device on the information input side (the HDD recorder 12 in the above case).

  Since the HDD recorder 11 confirms the password only for the password request program, the password confirmation is performed with the minimum necessary amount.

  In addition, when changing the reserved recording information that has already been transferred, for example, when changing the recording start time or the recording end time, there is a possibility of recording a program that is different from the program that was to be recorded before the change. is there. Therefore, in this case, it is necessary to reconfirm the viewing age restriction information. When changing the recording reservation set for the apparatus connected to the network 2, the transfer destination is determined based on the fact that the password has been confirmed in the transmission source apparatus as in the case of transferring the new reservation recording information. The device can also change the scheduled recording information.

  In the above-described embodiment, a case has been described in which password input is required, and whether or not password input is required is determined based on viewing age restriction information indicating whether or not a reserved program is a program with viewing age restriction. However, the present invention can also be applied to other cases that require password input (for example, in the case of PPV).

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

  In addition, the apparatus that transmits the reservation information to the HDD recorder 11 does not necessarily have an information recording unit like the HDD recorder 12. For example, a network I / F that performs data communication via the network 2 and a tuner, and includes a reservation information generation unit that generates the same reservation information as described above, and a password determination unit that determines whether the password is correct, Furthermore, it is good also as an information recording communication apparatus which has a notification control means which controls so that it may notify to HDD recorder 11 like the above whether the password has been confirmed.

  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 above description is the description of the embodiment of the present invention, and does not limit the apparatus and method of the present invention, and various modifications can be easily implemented. In addition, an apparatus or method configured by appropriately combining components, functions, features, or method steps in each embodiment is also included in the present invention.
