Description

  The present invention relates to a program data recording method and apparatus suitable for application to a recording apparatus that records, for example, a broadcast program on a recording medium such as a hard disk.

  2. Description of the Related Art Conventionally, a hard disk recording / reproducing apparatus using a hard disk as a recording medium has been put to practical use as a device for recording (recording) a television broadcast. In the case of this hard disk recording / reproducing apparatus, for example, a television broadcast signal of several tens of hours can be recorded with a recording capacity of several tens of Gbytes. The recordable time is expected to increase with the improvement of the recording density of a recording medium such as a hard disk and the improvement of the broadcast data compression technique.

  Some hard disk recording / reproducing apparatuses receive electronic program guide data called EPG (Electric Program Guide) so that a television program can be recorded easily. In the case of a broadcasting system such as digital satellite broadcasting, EPG data is added to the broadcasting data. In the case of terrestrial broadcasting that is analog broadcasting, the blanking period of a video signal of a specific channel, etc. In addition, only a specific time zone is added and sent. In addition to the transmission of the broadcast data, there is a form in which the data is distributed to the recording / playback apparatus on the user side via transmission means such as the Internet.

  The EPG data transmitted in this way is received, a television broadcast program guide is displayed on the screen of the receiver based on the received EPG data, and a program to be recorded is selected from the program guide. By performing the operation, the user can make a recording reservation for a desired program relatively easily.

  Further, by using a program guide based on EPG data, it is possible to make a reservation for a series program such as a series drama broadcast at a fixed time every day, for example. It is also possible to search for a program using a preset keyword and automatically reserve a program found by the search.

By the way, a receiving device for receiving television broadcasts and a device for recording program data such as a hard disk recording / reproducing device are configured separately, and the receiving device and the recording / reproducing device operate in conjunction with each other. In some cases, scheduled recording such as timer reservation is performed. Patent Document 1 discloses that timer reservation is performed when such a receiving apparatus and a recording apparatus are configured separately.
JP 2000-152100 A

  By the way, when the receiving device and the recording device are configured separately, there is a problem that a reserved program cannot be recorded correctly unless the receiving operation in the receiving device and the recording operation in the recording / reproducing device are linked. is there.

  That is, for example, when a recording of a program is reserved by a recording device and the reserved time is reached, a channel switching command is sent from the recording device to the receiving device so that the channel of the reserved program is received by the receiving device. It is necessary to control the device to receive the corresponding channel. However, the receiving apparatus cannot always switch channels by a command from the recording apparatus. For example, if the receiving device is in an operation mode in which a menu screen is displayed for various settings, the command may not be accepted even if a channel switching command is received. is there.

  Therefore, when the receiving device is in an operation mode in which the menu screen is displayed by a user operation or the like, even if a channel switching command is sent at the time reserved by the timer in the recording device, the channel switching is executed by the receiving device. In other words, the channel received by the receiving device is not the correct channel, and the program reserved by the recording device cannot be recorded.

  Some broadcast services received by the receiving device require a reception contract. As this contract, there is a case where a contract for charging is made for each channel and a case where a contract for charging is performed for each program called so-called pay-per-view. Even for channels that do not require charging, a contract may be required for copyright protection or the like. In general, for a channel for which no reception contract has been made, even if the receiving device attempts to receive the channel, the received signal is not scrambled and the program on that channel cannot be viewed. For example, in the case of a receiving device that receives a CS broadcast, the information regarding the reception contract is stored in an IC card built in the receiving device.

  Here, if it is assumed that a receiving device receives a channel that requires a contract and records it with a recording device, the channel reserved for recording by the recording device is a channel for which no receiving contract has been made on the receiving device side. In some cases, broadcast program data is output from the receiving device even if the receiving device selects the corresponding non-contracted channel and the recording device performs the recording operation under the control of the recording device. If the data is not scrambled (or scrambled data is output), the recording device cannot correctly record the program data. However, when a recording reservation is made on the recording device side, there is a problem that it is not known that the reserved program is not recorded until the user confirms the content recorded in the recording device.

  In addition, when the recording apparatus and the receiving apparatus are separately provided and the recording reservation process is performed under the control of the recording apparatus, the recording operation is controlled based on the time measured by the time measuring means (clock) built in the recording apparatus. However, if the time measured in the recording apparatus is not accurate, recording is performed at a time deviated from the actual broadcast time, which is not preferable. In the case of a broadcast recording device capable of recording reservation such as a conventional VTR device, for example, using a tuner built in the VTR device, the broadcast is directly received at the time when the time signal is broadcast, and the received time signal is received. The time of the built-in clock is corrected to match the time of broadcasting with the time of the clock in the VTR device, but the recording device and the receiving device are separate. However, it is difficult to do so, and it is necessary for the user to constantly correct the time of the recording device in order to link the recording device and the receiving device accurately.

  As described above, when the recording device and the receiving device are separate, there are various problems in executing recording reservation by linking both devices.

  The present invention has been made in view of these points, and when a broadcast program is recorded with the receiving device and the recording device as separate bodies, it is possible to accurately make a recording reservation by correctly linking both devices. The purpose is to.

  1st invention is a case where the program received by the receiver which receives a predetermined | prescribed broadcast service is recorded, The recording of the program broadcast by a predetermined | prescribed channel at a predetermined time is reserved, and the reserved program Control to change the receiving device to a mode in which the channel can be switched when the receiving channel is not the predetermined channel after sending a command to the receiving device to switch the receiving channel to the predetermined channel. After the mode change, a command for switching to a predetermined channel is sent again.

  According to a second aspect of the present invention, when recording of a program received by a receiving apparatus that receives a broadcast service requiring a contract for at least a part of channels or programs is reserved, the reserved predetermined channel or program is When it is a channel or program that requires a contract, contract information about that channel or program is acquired, and if it is a non-contracted channel or program based on the contract information, the recording reservation is canceled. is there.

  According to a third aspect of the present invention, when a program received by a receiving device that receives a predetermined broadcast service is recorded by a recording device different from the receiving device, the recording reservation time of the program is controlled by the recording device. When the time adjustment of the time measurement processing to be performed is performed, the time data included in the broadcast data received by the receiving device is sent to the recording device, the time adjustment is performed based on the sent time data, and the time adjustment processing of the time adjustment is performed. Based on the above, the program recording process is started when the reserved time comes.

  According to the first invention, when the broadcast signal reception device and the recording device are separate, and when the reserved recording such as timer recording is performed by the control from the recording device, the receiving device at the time of recording Even if channel switching is not possible due to some mode setting at the receiving device, etc., the mode is automatically changed to a mode that allows channel switching, and switching to the reserved channel is performed. In this case, channel switching is performed correctly, and recording errors due to channel switching errors can be eliminated.

  In this case, an inquiry is made as to whether or not it is possible to change to a mode that allows channel switching, and if there is an operation input that accepts the mode change as a response to the inquiry, the receiving device is changed to a mode that allows channel switching. By doing so, it is possible to prevent the mode set by the user operation or the like from being switched against the user's intention.

  According to the second aspect of the invention, it is possible to effectively prevent a channel set as non-contracted on the receiving apparatus side from being reserved for recording by the recording apparatus and performing a meaningless recording operation as it is.

  According to the third aspect of the invention, the time data included in the broadcast data is sent to the recording device by the receiving device, and the time is adjusted by the recording device. The time at which the program is received by the device coincides with the time at which the recording device records, so that a time lag when the recording device is separate from the receiving device can be prevented.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a diagram showing a system configuration example according to the present embodiment. In this example, a hard disk recording / reproducing apparatus 100 that records a television broadcast and a CS tuner apparatus 200 that receives a CS broadcast are connected, and a television receiver 300 is further connected. The hard disk recording / reproducing apparatus 100 is configured as a video recording / reproducing apparatus having a built-in hard disk for recording and reproducing a television broadcast program. The hard disk recording / reproducing apparatus 100 includes a tuner for receiving a terrestrial television broadcast. Is embedded, and for example, a terrestrial antenna 91 is connected. The CS tuner device 200 is a tuner that receives a CS broadcast. For example, a parabolic antenna 92 is connected to the CS tuner device 200, and a CS broadcast reception wave is supplied from a converter 93 attached to the parabolic antenna 92. The television receiver 300 uses another display device such as a monitor receiver as long as it can input the video signal and the audio signal from the hard disk recording / reproducing apparatus 100 and can display the video and output the audio. May be. The audio signal may be supplied to an audio output device different from the display device and output.

  The CS tuner device 200 is configured to receive two CS broadcast services. The video signal and the audio signal of the television broadcast (CS broadcast) received by the CS tuner device 200 are connected to cables 83 and 84, respectively. To the hard disk recording / reproducing apparatus 100. Note that the two broadcast services are different satellites that relay radio waves, and the format of broadcast data is also slightly different. Also, the hard disk recording / reproducing apparatus 100 and the CS tuner apparatus 200 are connected to each other by a data communication port prepared for each device via a cable 85 so that bidirectional communication can be performed. Data or the like can be sent to the hard disk recording / reproducing apparatus 100.

  The hard disk recording / reproducing apparatus 100 records the terrestrial television broadcast program received by the built-in terrestrial tuner to the hard disk and the hard disk of the CS broadcast television broadcast program received by the connected CS tuner apparatus 200. Can be recorded.

  In the case of this example, the CS broadcast service received by the CS tuner device 200 is a digital broadcast service in which video signals and audio signals converted into digital data are transmitted, and packets in which these data are transmitted include Electronic program data called EPG data is added. The packet to which the electronic program data is added is sent from the CS tuner device 200 to the hard disk recording / reproducing device 100 via the data communication port.

  Further, a control signal for controlling the operation of the CS tuner device 200 can be transmitted from the hard disk recording / reproducing device 100 side through the connection between the data communication ports. As commands (commands) by the control signal, there are a power ON / OFF command for the CS tuner device 200, a channel switching command, a switching command for a broadcast service to be received, a switching command for an operation mode, and the like. However, the broadcast service switching command to be received is not necessary depending on the configuration of the CS tuner device 200 to be connected. Further, instead of a command for directly instructing an operation, a command for inquiring about the current operation state of the CS tuner device 200 (for example, an inquiry about whether the power is on or in a standby state) may be sent.

  The video signal and audio signal output from the hard disk recording / reproducing apparatus 100 are connected to the television receiver 300 via cables 81 and 82. The television receiver 300 can display video and output audio recorded on a hard disk built in the hard disk recording / reproducing apparatus 100. Although not shown in FIG. 1, the CS tuner device 200 and the television receiver 300 may be directly connected. Further, a video signal source other than the CS tuner device 200 can be connected to the hard disk recording / reproducing apparatus 100, and a video signal and an audio signal supplied from the video signal source can be recorded on the hard disk.

  Next, the configuration of the hard disk recording / reproducing apparatus 100 will be described with reference to FIG. A terrestrial antenna 91 connected to the hard disk recording / reproducing apparatus 100 is connected to a terrestrial tuner 101 built in the apparatus 100, and a terrestrial television broadcast video signal obtained by the tuner 101 is obtained. The audio signal is supplied to the terminal 111 of the changeover switch 110.

  The reception channel in the terrestrial tuner 101 is controlled by the controller 121 of the recording / reproducing apparatus 100. The terrestrial wave received by the tuner 101 is an analog broadcast wave, but for a predetermined specific channel, data is superimposed on the blanking period of the video signal several times a day at a predetermined time. Thus, EPG data for displaying the electronic program guide is sent. This EPG data is not only a guide for the channel on which the EPG data is superimposed, but also data for guiding a program for most terrestrial channels that can be received in the area. Therefore, the tuner 101 functions as a program data acquisition unit that extracts the EPG data superimposed on the channel by receiving the channel on which the EPG data is superimposed (added) at the time when the EPG data is superimposed. The EPG data received by the tuner 101 is sent to the controller 121. The controller 121 of this example has a function as processing means for extracting only necessary program data from the supplied EPG data. Details of processing for extracting only necessary program data will be described later.

  The change-over switch 110 is a switch that switches between a signal received by the tuner 101 and a signal obtained from the external input terminals 131, 132, 133, and 134. The input terminals 131 and 132 are a video signal input terminal and an audio signal input terminal used as the first input unit, and supply signals obtained from these input terminals to the terminal 112 of the changeover switch 110. The input terminals 133 and 134 are a video signal input terminal and an audio signal input terminal used as the second input unit, and supply signals obtained at these input terminals to the terminal 113 of the changeover switch 110. Of these video and audio signals obtained at the terminals 111, 112, and 113, a signal selected by the control of the controller 121 is obtained at the terminal 114. In FIG. 2, when the supply and switching of the video signal and the audio signal are performed simultaneously, the transmission path of both signals is shown by one transmission line.

  Of the external input units, the first input units (input terminals 131 and 132) are used as dedicated input terminals to which video signals and audio signals received and output by the CS tuner device 200 are supplied. The However, when the CS tuner is not connected, another video signal source may be connected to the first input unit.

  The second input unit (input terminals 133 and 134) is connected to a video signal source from which video signals and audio signals to be recorded by the hard disk recording / reproducing apparatus 100 are output. For example, a BS tuner or a video tape recording / reproducing device is connected.

  The video signal and the audio signal (the signal obtained at the terminal 114) selected by the changeover switch 110 are supplied to an MPEG (Moving Picture coding Experts Group) encoder 102, and digital video data compressed and encoded by, for example, the MPEG2 system, Digital audio data. Since the signal supplied to the encoder 102 is an analog signal, digital conversion for converting the analog signal into digital data is also performed in the encoder 102 (or a separate circuit).

  MPEG-2 video data and audio data obtained by the MPEG encoder 102 are supplied to the recording / playback processing unit 103. The recording / playback processing unit 103 is a circuit that performs processing for recording and playing back video data, audio data, and the like on the hard disk 105. A buffer memory 104 is connected to the recording / playback processing unit 103, and recording and playback are performed while temporarily storing data in the buffer memory 104. The hard disk 105 is also used as storage means (recording means) for electronic program data. That is, the electronic program data processed by the controller 121 is recorded on the hard disk 105 and reproduced under the control of the controller 121. However, for the electronic program data, a memory (not shown) connected to the controller 121 may be used as the storage means without using the hard disk 105 as the storage means. The hard disk 105 is configured to be recorded and reproduced by a head while being rotated at high speed by a spindle motor. For example, a television broadcast signal of several tens of hours can be recorded with a recording capacity of several tens of Gbytes. is there.

  The video data and audio data reproduced from the hard disk 105 and processed by the recording / reproduction processing unit 103 are supplied to the MPEG decoder 106 and decoded from the MPEG2 system. The decoded video data is supplied to the NTSC encoder 108 via the mixer 107 and supplied to the output terminal 135 as an NTSC analog video signal. The decoded audio data is converted into an analog audio signal by the digital / analog converter 109, and the analog audio signal is supplied to the output terminal 136. The output terminals 135 and 136 correspond to terminals connected to the television receiver by the cables 81 and 82 in FIG.

  Further, the hard disk recording / reproducing apparatus 100 of this example includes a data communication port 137 for communicating with the CS tuner apparatus 200. From the data transmitted from the CS tuner device 200 side through the data communication port 137, necessary data is extracted by the interface 122 and sent to the controller 121. As data sent from the CS tuner apparatus 200 to the recording / reproducing apparatus 100, for example, there is electronic program data. Further, data (such as various commands described in the description of FIG. 1) to be sent from the controller 121 to the CS tuner device 200 side is output from the data communication port 137 via the interface 122.

  A command for operating the hard disk recording / reproducing apparatus 100 is supplied from an input unit 123 including an operation key and a remote control signal receiving unit (light receiving unit). For example, when an operation command is received by an infrared signal from a remote control device (not shown), the received command is sent to the controller 121. As a command by a remote control device or key operation, for example, in addition to a command directly instructing recording, playback, channel switching, etc., refer to display on the receiver 300 connected to the hard disk recording / playback device 100 On the other hand, there is also a so-called GUI (Graphical User Interface) operation command for performing a multi-function operation by operating a cursor key or a confirmation key.

  When the controller 121 performs processing for generating a screen for the GUI operation, the controller 121 sends the generated screen data to the mixer 107, mixes it with the video data output from the MPEG decoder 106, and outputs the output terminal 135. The video signal output from is a video signal for displaying a corresponding screen.

  If it is necessary to perform various displays on the hard disk recording / reproducing apparatus 100 other than the GUI operation screen, the controller 121 similarly generates the display screen data and sends it to the mixer 107. It is. Examples of screens displayed by these processes will be described later.

  A clock unit 124 is connected to the controller 121, and the controller 121 determines the result of counting the current time (year / month / day, hour / minute / second) at any time by the clock unit 124. The controller 121 determines the date and time counted by the clock unit 124, and the reserved recording is executed. In the case of this example, the time counted by the clock unit 124 is automatically corrected based on the signal received by the connected CS tuner device 200. The automatic time correction process will be described later.

  The hard disk recording / reproducing apparatus 100 of this example incorporates three light emitting diodes 141, 142, and 143 as lighting means in the front panel section of the apparatus, and is driven by the lighting control section 140 based on the control of the controller 121. The lighting of the three light emitting diodes 141 to 143 is individually controlled. The three light emitting diodes 141 to 143 have different colors for emitting light, for example. In the case of this example, when there is a new recording (specifically, a series reservation) due to light emission by these three light emitting diodes 141 to 143, it is used as a means for notifying that.

  Also, the hard disk recording / reproducing apparatus 100 of this example includes a card slot 125 into which a memory card can be detachably attached. The controller 121 reads out data stored in the memory card 126 attached to the card slot 125, and various It can be processed. For example, when still image data or moving image data is stored in the attached memory card 126, the controller 121 reads out the image data and sends it to the mixer 107, and a receiver connected to the recording / reproducing apparatus 100. 300 can be displayed. Alternatively, data read from the memory card 126 may be recorded on the hard disk 105 or the like.

  Furthermore, the hard disk recording / reproducing apparatus 100 of this example includes a port 138 for connecting to the Internet, and data exchange via the communication means connected by the Internet connection port 138 is performed via the interface 127. It can be done with.

  The Internet connection port 138 can be connected to, for example, a router or modem for Internet connection via a predetermined cable. Electronic program data can also be obtained by accessing a server at a predetermined address via the Internet connection port 138.

  When the electronic program data is acquired by various processes, the controller 121 stores the electronic program data in a partial area of the hard disk 105 and uses the stored data to display the electronic program guide. Or, a recording reservation process is performed. The electronic program data acquired by the controller 121 includes the electronic program data received by the built-in tuner 101, the electronic program data obtained from the connected CS tuner device 200 via the port 137, and the Internet. There are three types of acquired electronic program data, and which electronic program data is used is determined in advance by setting.

  Note that a non-volatile memory (not shown) is connected to the controller 121 so as to store various setting items. The recording reservation information is also stored in this nonvolatile memory. However, a part of the recording area of the hard disk 105 may be used instead without providing a non-volatile memory.

  Next, the configuration of the CS tuner apparatus 200 connected to the hard disk recording / reproducing apparatus 100 of this example will be described with reference to FIG.

  The CS tuner device 200 is connected to a parabolic antenna 92 that receives satellite broadcast waves. The tuner 201 receives a packet including data of a channel to be received from signals supplied from a converter 93 of the parabolic antenna 92. Process. The selection of a packet to be received is controlled by the controller 210. The packet received by the tuner 201 is supplied to a QPSK (Quadrature Phase Shift Keying) demodulator 202 to perform QPSK demodulation processing on the received packet data. The demodulated data is supplied to the error correction unit 203 to perform error correction processing.

  The error-corrected received data is supplied to the demultiplexer 204, and the received video data, audio data, and other data are extracted from the received packet. Examples of other data include electronic program data. This extraction processing is executed based on the control of the controller 210, and temporary storage of data necessary for data processing is performed by the connected buffer memory 205.

  The video data and audio data extracted by the demultiplexer 204 are supplied to the MPEG decoder 206, and the video data and audio data encoded by the MPEG-2 system are decoded. The video data decoded by the MPEG decoder 206 is supplied to the NTSC encoder 208 via the mixer 207 and supplied to the output terminal 221 as an NTSC analog video signal. The decoded audio data is converted into an analog audio signal by the digital / analog converter 209, and the analog audio signal is supplied to the output terminal 222. These output terminals 221 and 222 correspond to terminals connected to the hard disk recording / reproducing apparatus 100 by the cables 83 and 84 in FIG. The electronic program data extracted by the demultiplexer 204 is sent to the controller 210.

  The video signal output from the terminal 221 may be a video signal based on various guidance display images generated by the controller 210. In other words, the guide display image data generated by the controller 210 can be supplied to the mixer 207, superimposed on the video data output from the MPEG decoder 206, and supplied to the NTSC encoder 208. The image data for displaying guidance includes, for example, image data for displaying an electronic program guide based on the electronic program data added to the received channel signal.

  Further, the CS tuner device 200 of this example includes a data communication port 223 for communicating with the hard disk recording / reproducing device 100. The data communication port 223 is connected to the data communication port 137 on the hard disk recording / reproducing apparatus 100 side by a dedicated cable (cable 85 shown in FIG. 1). Broadcast data to be transmitted using the data communication port 223 is transmitted from the demultiplexer 204 to the interface 211 and output as data in a format to be output from the port 223 by the interface 211. In the case of this example, the packet itself containing the received broadcast data (that is, data containing video data, audio data, EPG data, etc.) is sent from the port 223 to the hard disk recording / reproducing apparatus 100 side. . On the hard disk recording / reproducing apparatus 100 side, only EPG data is extracted from the transmitted packet data.

  Further, when data (such as various commands) sent from the hard disk recording / reproducing apparatus 100 side is received by the interface 211 via the data communication port 223, the data is sent to the controller 210. Data may be sent from the controller 210 to the hard disk recording / reproducing apparatus 100 side via the interface 211.

  A command for operating the CS tuner device 200 is supplied from an input unit 212 configured by an operation key or a remote control signal receiving unit (light receiving unit). For example, when an operation command reaches the input unit 212 by an infrared signal from a remote control device (not shown), the received command is sent to the controller 210.

  Further, the CS tuner device 200 is configured to be mounted with an IC card 213 that holds data relating to a reception contract such as user registration information and viewing records. Based on information stored in the IC card 213, a controller is provided. 210 performs processing such as reception of a pay channel. With respect to a pay channel or program for which the reception information is not subscribed by the stored information of the IC card 213, control is performed so that the program of the channel is not descrambled even if the channel is selected.

  Further, the CS tuner device 200 includes a telephone line connection terminal 224, and data can be sent from the controller 210 to the telephone line connected to the terminal 224 via the interface 214. As data to be transmitted through the telephone line, there is data related to a reception contract such as a pay channel viewing record.

  As already described, the CS tuner device 200 of this example can receive two broadcast services (service A and service B), and the satellites received for each broadcast service are different, but the service A In the case of switching to the service B channel (or vice versa) from the state where the channel is received, a tuner of the type that requires the channel switching operation after the satellite switching operation is performed due to the tuner configuration. There are two types of tuners in which broadcasting services are automatically switched only by channel switching operation. There are many types of tuners that require satellite switching operations in older tuners.

  Next, the hard disk recording / reproducing apparatus 100 and the CS tuner apparatus 200 configured as described above are connected as shown in FIG. 1, and processing for recording (recording) and reproducing by the hard disk recording / reproducing apparatus 100 is shown in FIG. Description will be made with reference to the flowcharts of FIGS. 4 to 14 and display examples of FIG. The user operation for performing these processes is performed by, for example, a remote control device (not shown) attached to the hard disk recording / reproducing device 100. Specifically, with the video (video for GUI operation) output from the output terminal 135 of the hard disk recording / reproducing device 100 being displayed on the television receiver 300, the cursor key and the decision key of the remote control device are displayed. Each item is input by operation. The display examples after FIG. 15 are examples of the screen for GUI operation.

  As described above, the recording of the broadcast program in the hard disk recording / reproducing apparatus 100 of this example includes the recording of the terrestrial television broadcast program received by the tuner 101 built in the recording / reproducing apparatus 100 and the CS tuner apparatus. There is a recording of a television broadcast program of CS broadcast waves received at 200. In order to record these broadcast programs, the hard disk recording / reproducing apparatus 100 first needs to be set up. This setup process is executed under the control of the controller 121, and the setup items are stored (recorded) in a non-volatile memory (not shown) connected to the controller 121, a hard disk, or the like.

  FIG. 4 is a flowchart showing an example of the setup process. First, the controller 121 of the hard disk recording / reproducing apparatus 100 determines whether or not the user's operation is a selection for displaying a setup screen (step S11). At this time, if the display of the setup screen is not selected, the process proceeds to another process. If display of the setup screen is selected, the setup screen is displayed. In the case of the initial setting, the setup screen may be automatically displayed in conjunction with the power-on of the hard disk recording / reproducing apparatus 100.

  FIG. 15 shows a first display example of the setup screen, and a menu for performing setup is displayed. That is, as shown in FIG. 15, there is a setup display 11 on the upper side of the screen, and a setup menu display 12 on the left side. Here, the channel alignment display 12a in the menu is selected, and when the channel alignment display 12a is selected, an item 13 for channel alignment is displayed on the right side.

  In a state where the setup screen is displayed, it is determined whether or not channel adjustment in the setup menu displayed on the screen is selected (step S12). When the channel matching is selected, it is further selected whether the channel matching is for the terrestrial wave or the channel matching for the CS channel (step S13).

  As shown in FIG. 15, in the state where the channel alignment display 12a is selected, three items of [terrestrial channel], [CS channel], and [automatic terrestrial channel alignment] are displayed as the item 13 for channel alignment. Is displayed.

  Here, when the terrestrial channel setting is selected, a screen for inputting a code number (region number) assigned to each region where this system is installed is displayed by a user operation. The area number is input (step S14). FIG. 17 is a diagram showing an example of an area number input screen. A display area 15 for inputting an area number is prepared.

  When an area number is entered in the display shown in FIG. 17, a list of terrestrial television broadcast channels that can be received in that area is displayed on the screen (step S15). The channel number and broadcast station name data that can be received for each area number are stored in advance in a memory connected to the controller 121 of the hard disk recording / reproducing apparatus 100.

  FIG. 18 is an example of a reception channel confirmation screen displayed based on the input of the area number. Here, a list display 16 of received channel numbers, a list display 17 of channel numbers to be displayed, and a list display 18 of broadcast station names are performed. By changing the channel number in the list display 17, the channel number actually displayed on the screen at the time of reception can be changed from the reception number. Such a change makes it possible to match the channel number displayed when receiving a so-called satellite station with the channel number remembered by the user. In the case of terrestrial waves, the EPG data is transmitted only through a specific channel determined in advance for each region. When the channel is set by inputting this region number, the EPG is transmitted. The channel number received when acquiring data is also automatically set to the corresponding channel number based on data prepared in advance.

  As shown in FIG. 18, the user confirms the list display of the displayed reception channels, and if that is sufficient, the process proceeds to the next process. The user confirms the list display of the reception channels, and if there is a channel to be added or deleted as a receivable channel, a corresponding user operation is performed. Although not shown in the flowchart of FIG. 4, instead of inputting the area number shown in step S14, a channel to be registered may be selected by a user operation for each station. When registering one station at a time, it is necessary to register a channel for acquiring terrestrial EPG data by a user operation.

  The reception channel selected in the process so far is a terrestrial channel that can be received by the tuner 201 under the control of the controller 121. That is, for example, when the channel up key or the channel down key of the remote control device is operated, among the selected reception channels, the reception channels change in order of channel numbers.

  When the setting of channels to be received by terrestrial is completed, a screen for selecting a channel to be registered as a channel for automatic recording is displayed from the received channels (step S16). In this automatic recording, the controller 121 determines the electronic program data of the broadcast channel, searches for a program that matches a predetermined condition, and automatically performs recording reservation for the searched program. As a predetermined condition, for example, when a specific keyword is included in the program name or program guideline indicated by the electronic program data, the program is automatically reserved for recording, and the program is automatically This is a process of recording on a hard disk.

  FIG. 19 is a diagram showing an example of a setting screen for a terrestrial automatic recording channel. In this example, a list display 19 of display channel numbers, a list display 20 of broadcast station names corresponding thereto, and an automatic recording setting display 21 for each channel are performed. By performing an operation of selecting whether or not to automatically record the display for each channel in the automatic recording setting display 21, settings can be made for each channel.

  For a channel selected as a channel for automatic recording among the received channels based on the display in step S16, if a program matching a certain condition is found based on the designation of a keyword or the like, The controller 121 automatically schedules recording of the program. Further, such automatic recording processing is not performed for a channel selected as a channel for which automatic recording is not performed among the reception channels based on the display in step S16. For channels that are not selected as automatic recording channels, recording by a user operation (herein, such recording is referred to as manual recording in order to distinguish it from automatic recording) is possible.

  If it is selected in step S13 that the channel setting is for the CS channel, the controller 121 displays the input screen for the channel number to be received, and allows the user to input the channel number to be received on the input screen. . The hard disk recording / reproducing apparatus 100 of this example can set a maximum of 20 channels as channels that can be instructed to be received from this apparatus to the CS tuner apparatus 200 side. The 20 channels may include two broadcast services that can be received by the CS tuner device 200.

  FIG. 20 is an example of a channel number input screen for the CS channel. In this example, the display 22 of the area where the channel number can be input is displayed one by one in order, and the display 22 of the area is increased every time the input of the channel number is completed, and the maximum 20 channel numbers are obtained. It can be input. In the example of FIG. 20, each channel number is shown as a three-digit number.

  When the channel number is input in step S17 and the confirmation operation is performed, a list of broadcast station names of the input channel number is displayed (step S18). The correspondence between the channel number and the broadcasting station name may be stored in the hard disk recording / reproducing apparatus 100 in advance, or may be obtained based on data received by the connected CS tuner apparatus 200. The CS broadcast reception channel displayed in the list in step S18 is a channel that can be reserved for recording based on the electronic program data in the hard disk recording / reproducing apparatus 100 of this example.

  FIG. 21 is a display example of a list of broadcast station names of channel numbers of the CS channel. Here, a list display 24 of reception channel numbers, a list display 25 of corresponding broadcast station names, and a list display 26 of broadcast services are performed. As already described, there are two types of broadcast services that can be received by the CS tuner device 200 of the present example (herein referred to as service A and service B), and radio waves are transmitted (relayed) for each broadcast service. Different communication satellites.

  When the user confirms the list display of the CS broadcast reception channels in step S18, a screen for selecting a channel to be registered as a channel for automatic recording is displayed next among the CS broadcast reception channels (step S19). . The automatic recording here is the same as the automatic recording on the terrestrial wave. The controller 121 judges the electronic program data of the broadcast channel, searches for a program that matches a predetermined condition, and records the searched program. This is a process for automatically making a reservation.

  FIG. 22 is a display example of automatic recording channel setting of the CS channel. Here, a reception channel number list display 27, a corresponding broadcast station name list display 28, and an automatic recording setting display 29 for each channel are performed. By performing an operation of selecting whether or not to automatically record the display for each channel in the automatic recording setting display 29, the setting can be made for each channel.

  As for the CS channel selected as the channel for automatic recording among the received channels based on the display in step S19, if a program matching a certain condition is found based on the designation of a keyword or the like, The controller 121 automatically schedules recording of the program. In addition, based on the display in step S19, such automatic recording processing is not performed for the CS channel selected as a channel for which automatic recording is not performed among the reception channels. For channels that are not selected as automatic recording channels, manual recording is possible in which an electronic program guide is displayed and a program to be recorded is selected by the user operation.

  If it is determined in step S12 that an item other than channel matching has been selected from the setup screen, it is determined whether or not a setting related to CS broadcast reception (except channel setting) has been selected (step S20). If it is a broadcast reception setting, a screen for inputting the corresponding item is displayed (step S21).

  FIG. 16 is a display example of a setup menu related to CS broadcast reception settings. In this example, the CS setting display 12b is selected from the menu display 12, and a detailed list display 14 regarding CS setting is performed on the right side of the screen. The detailed list display 14 will be described in order. The CS function on / off display 14a, the manufacturer name display 14b of the connected CS tuner device 200, the satellite switching transmission on / off display 14c, Display 14d indicating whether tuner power control is linked or not linked, display 14e of channel number for acquiring EPG data for displaying electronic program guide in service A, and EPG data for displaying electronic program guide in service B A channel number display 14f for acquiring EPG data and a desired time display 14g for acquiring EPG data are displayed.

  In the state in which the CS broadcast reception setting screen shown in FIG. 16 is displayed, each display item is selected and an operation for changing it can be performed to set the user's favorite setting state. Explaining each item in detail, the CS function can be controlled by turning the CS function “ON” on the CS function ON / OFF display 14a. Such a control is not performed. By correctly setting the manufacturer name of the connected CS tuner device 200 on the display 14b of the manufacturer name of the connected CS tuner device 200, correct operation control of the CS tuner becomes possible.

  By setting “ON” in the ON / OFF display 14c of the satellite switching transmission, when the CS broadcasting service switches the channel to a different channel, a satellite switching command is sent to the CS tuner device 200, and then the channel number The command will be sent. When “OFF” is set, the channel number command is sent directly without sending the satellite switching command even when the CS broadcast service switches the channel to a different channel. In the case of outputting a satellite switching command, it is necessary to open several seconds after the satellite switching command is output until the channel number command is transmitted.

  In the display 14d of whether the tuner power control is linked or not linked, when “linked” is set, the power source of the CS tuner device 200 is turned on only when the hard disk recording / reproducing device 100 needs to operate the CS tuner device 200. The on state is set, and in other cases, the off state (or the standby state) is set. When “not interlocked” is set, the power supply of the CS tuner is not controlled from the hard disk recording / reproducing apparatus 100. Therefore, when making a reservation for CS channel recording after setting “non-interlocking”, it is necessary to keep the CS tuner device 200 powered on.

  The channel number display 14e for acquiring EPG data for displaying the electronic program guide in the service A and the channel number display 14f for acquiring EPG data for displaying the electronic program guide in the service B are the respective services. The channel number with which the electronic program data can be most satisfactorily acquired is preset. In the case of this example, the channel number of the promotion channel prepared for each service is set when the hard disk recording / reproducing apparatus 100 is shipped. However, since the channel number of the promotion channel may be changed, in such a case, user input is performed to change the channel number displayed on the display 14e or 14f.

  About the display 14g of the desired time for acquiring the EPG data, the time for starting the acquisition of the EPG data of the CS channel is displayed. The EPG data of the CS channel can be acquired at any time as long as it is basically within the broadcasting service period, but it takes a relatively long time to acquire the EPG data. It is necessary to set the acquisition time so that it does not overlap with the time reserved for recording as much as possible, and it is preferable to set the time when the program that the user needs is basically unlikely to be broadcast.

  Although an example of the screen is not shown, the terrestrial EPG data can also be set (changed) by displaying the acquisition time on the terrestrial broadcast setting screen. However, terrestrial EPG data is currently transmitted only a few times a day at a predetermined time, and can be selected only from the several transmission times. The time zone that can be set as the EPG data of the CS channel is to avoid the acquisition time zone of the terrestrial EPG data.

  Here, an example of processing in the controller 121 when the channel number displays 14e and 14f for acquiring EPG data in the display example of FIG. 16 are changed will be described with reference to the flowchart of FIG. First, in the state where the setup menu shown in FIG. 16 is displayed, it is determined whether or not there is an input for changing the acquisition channel of the EPG data of service A (step S31). It is determined whether or not there is an input for changing the acquisition channel of B EPG data (step S32). If there is an input for changing the EPG data acquisition channel of any service, the changed channel number is registered as a channel to be received when EPG data is acquired in the corresponding service, and stored in the nonvolatile memory or hard disk. (Step S33) The channel number displayed as the display 14e or 14f is changed to the registered channel number (Step S34).

  As described above, since the channel number for acquiring the data of the electronic program guide can be changed, even when the channel number of the promotion channel is changed on the broadcasting service side, it is possible to easily cope with the user operation.

  Next, an example of processing in the controller 121 when setting the time to acquire EPG data for displaying the electronic program guide will be described with reference to the flowchart of FIG. First, if there is an operation for changing the acquisition time of EPG data, it is determined whether or not the operation is for changing the acquisition time of EPG data for terrestrial waves (step S35). Here, in the case of changing the acquisition time of terrestrial EPG data, only a plurality of times for which EPG data is determined to be transmitted in advance are displayed as candidates, and only from among the candidate times, One of them can be selected (step S36). In the setting screen, for example, only the time for starting the acquisition of EPG data is displayed, but in practice it takes a relatively long time to acquire the EPG data. Next, it is determined whether or not the operation is for changing the acquisition time of EPG data of the CS channel (step S37). When changing the acquisition time of CS channel EPG data, a plurality of candidate times are displayed from a time zone that does not overlap with the time zone for acquiring terrestrial EPG data. Any one of them can be selected (step S38).

  When the EPG data acquisition time has been set so far, it is determined whether or not there is a recording reservation for a time that overlaps the acquisition time zone set at that time (step S39). Here, if there is a recording reservation for a time that overlaps the acquisition time, a warning indicating that the recording reservation overlaps is displayed on the setup screen at that time (step S40). You may make it accept the consent from a user for the display of this warning. If accepted, the recording reservation is canceled (step S55). If not accepted, the process returns to step S35. If acceptance is not accepted, the process proceeds directly to step S55.

  A user who has confirmed from the warning display that the EPG data acquisition time zone and the recording reservation overlap can change the EPG data acquisition time or change the recording reservation time, thereby avoiding malfunctions that do not work correctly. .

  Next, a process for actually obtaining EPG data after the setup in the hard disk recording / reproducing apparatus 100 is completed will be described. First, processing for acquiring terrestrial EPG data under the control of the controller 121 will be described with reference to the flowchart of FIG.

  The controller 121 determines whether or not it is time to acquire terrestrial EPG data from the time counted by the clock unit 124 (step S41), and waits until it is time to acquire terrestrial EPG data. When it is determined that it is time to acquire terrestrial EPG data, the tuner 101 receives a channel for acquiring pre-registered terrestrial EPG data (step S42). Upon reception, EPG data is acquired (step S43). This acquisition process is started, and it is determined whether or not all of one unit of EPG data has been acquired (step S44), and is performed until the acquisition is completed. In the case of this example, the electronic program guide data from the current day to one week ahead is acquired for all the channels broadcast in the area (except for some channels that do not have EPG data).

  If all the one unit of EPG data has been acquired, the acquired EPG data is stored in the hard disk (step S45). Note that storage to the hard disk may be performed sequentially in parallel with data acquisition.

  Then, the EPG data stored in the hard disk is organized into a data structure in a form that can be easily used by the recording / reproducing apparatus 100 (step S46), and the terrestrial EPG data acquisition process is terminated.

  The terrestrial EPG data acquisition process shown in the flowchart of FIG. 7 is a process for acquiring EPG data added to the terrestrial broadcast data. The device 100 is configured to be connected to the Internet, and can also access a predetermined server via the Internet and accumulate EPG data sent from the server. Whether it is EPG data acquired via the Internet or EPG data extracted from a broadcast wave, a recording reservation described later can be executed in the same way. However, in order to perform a keyword search described later, detailed program guide information is necessary, and it is preferable to use EPG data composed of more detailed data.

  Next, processing for acquiring CS broadcast EPG data under the control of the controller 121 will be described with reference to the flowchart of FIG.

  The controller 121 determines whether or not it is time to acquire CS broadcast EPG data from the time counted by the clock unit 124 (step S51), and waits until it is time to acquire CS broadcast EPG data. When it is determined that it is time to acquire CS broadcast EPG data, it is determined whether or not the currently connected CS tuner device 200 is powered on (step S52), and the CS tuner device 200 is powered on. If not, a command to turn on the tuner is sent to the CS tuner device 200 (step S53). Note that the determination of the power-on state in step S52 may be performed if the state of the CS tuner device 200 can be detected by communication with the CS tuner device 200. In addition, when the status of the CS tuner device 200 cannot be detected, it is determined that the power is on when the reception data is currently supplied from the CS tuner device 200. When the reception data is not supplied, the power is on. Judge that it is not. Further, when the power supply of the CS tuner device 200 is set to non-interlocking, the processing in steps S52 and S53 is not necessary.

  Then, after determining that the power is turned on in step S52 and sending a power-on command in step S53, a channel switching command for receiving the promotion channel of service A or service B registered in advance is sent (step S54). The service received here is assumed to be the service to which the channel with the smallest channel number belongs, for example, in the case of receiving sequentially from the registered channel with the smallest channel number. Here, the following description will be made assuming that reception is performed in the order of channel numbers. Here, when a CS tuner that requires a satellite switching operation is connected, it is necessary to send a satellite switching command to the desired satellite forcibly and then send a channel switching command. When the satellite information at the time of the previous satellite switching command is stored in the memory connected to the controller 121, the satellite switching command is used only when it is determined that the satellite switching is necessary based on the information. May be sent.

  Therefore, processing for obtaining EPG data for the smallest channel number is performed (step S55), and it is determined whether or not the electronic program guide data for that channel number from the current day to one week ahead can be obtained (step S55). Step S56). It takes about 1 minute to acquire the electronic program guide data for one channel for one channel, for example, and the acquisition in step S55 until the electronic program guide data for one week for the corresponding channel can be acquired. Process. If the electronic program guide data for one week of the corresponding channel can be acquired, the EPG data for one week is stored in the hard disk (step S57).

  Next, it is determined whether or not the next smaller channel number among the registered reception channels is the same broadcast service channel as the channel number from which EPG data was acquired immediately before (step S58). If there is, it is switched to reception of a promotion channel for another broadcasting service (step S59). Here, when a CS tuner that requires satellite switching operation is connected, it is necessary to send a channel switching command after sending a satellite switching command.

  Then, when it is determined in step S58 that the broadcasting service is the same, and after the processing of step S59 is performed, processing for acquiring EPG data for the channel acquired at that time is performed (step S60), and the channel number is acquired. It is determined whether or not the electronic program guide data for 1 week from the current day has been acquired (step S61). If the electronic program guide data for one week of the corresponding channel can be acquired, the EPG data for one week is stored in the hard disk (step S62).

  The processing from step S58 to step S62 is repeated as long as there is a channel registered to be received. In the case of this example, the maximum number of CS broadcast channels that can be registered is 20, so the EPG data acquisition process is performed up to 20 times. When the EPG data can be acquired for all the registered channels and stored in the hard disk, a command to turn off the power is sent to the CS tuner device 200 (step S63), and the CS tuner device 200 is put into a standby state. However, if the power supply of the CS tuner device 200 is set to non-interlocking, the process in step S63 is not necessary.

  Thereafter, the EPG data stored in the hard disk is converted into a data format that can be easily used by the hard disk recording / reproducing apparatus 100 (step S64), and the CS broadcast EPG data acquisition process ends here. If it takes about 1 minute to acquire EPG data for one CS channel, it is possible to register up to 20 channels, so it is necessary to receive up to about 20 minutes. For example, about 10 minutes are required, and a total time of about 30 minutes is required.

  Since the EPG data can be stored in the hard disk recording / reproducing apparatus 100 in this way, the program guide is displayed on a connected television receiver or the like based on the stored EPG data, and displayed by a GUI operation or the like. By performing an operation of selecting a program to be recorded from the program guide, a program to be reserved for recording can be easily selected. In addition to recording reservation by user operation, for example, a program with a specific keyword is automatically reserved based on EPG data, or a program of a specific series is searched from EPG data and automatically recorded. Various forms of recording reservation such as making a reservation are assumed. The recording reservation described in the following description includes cases where recording is reserved in any form.

  When the recording reservation for the CS channel program is performed in this manner, the controller 121 of the hard disk recording / reproducing apparatus 100 causes the time measured by the timer unit 124 to be slightly before the recording start time reserved for recording. When it becomes (for example, several minutes before), the reservation recording pre-processing is started. FIG. 9 is a flowchart showing the pre-recording reservation process of this example. 9 will be described below. First, the controller 121 transmits a channel selection command for causing the CS tuner 200 to perform channel switching via the data communication port 137 and receives a channel reserved by the CS tuner 200. (Step S71). In this case, before sending the channel selection command, a service switching command (service A, service B switching command) is sent depending on the tuner configuration.

  After sending this channel selection command, the controller 121 of the hard disk recording / reproducing apparatus 100 is currently receiving in order to confirm whether the channel received by the CS tuner 200 is the channel designated by the channel selection command. Is sent to the CS tuner 200 side via the data communication port 137 (step S72). Then, the controller 121 receives a response to the command (step S73). Here, when the reception channel indicated by the received data is the same as the channel specified by the channel selection command, it is determined that the channel selection has succeeded, and the CS tuner 200 determines that the reserved time is reached. A recording process for recording the video signal and the audio signal supplied to the hard disk recording / reproducing apparatus 100 as program data on the hard disk is started (step S75).

  If it is determined in step S74 that the channel selection is not successful (that is, the reception channel is not the channel designated by the channel selection command), the television receiver connected to the hard disk recording / reproducing apparatus 100 is received. In the video displayed on the device 300, the fact that the channel selection has failed is displayed in a pop-up display on the screen (step S76). For example, as shown in FIG. 23, a display 1001 indicating that the channel selection has failed is made, “Channel selection failed for reserved recording. A button display 1002 according to the display and a button display 1003 not according to the display are displayed. The user performs an operation of selecting one of the button displays using a remote control device or the like.

  Here, it is determined whether or not there is an operation for selecting one by the user (step S77). If there is no operation, it is determined whether or not the time after starting the display of FIG. 23 has reached the timeout time (step S81), and the process returns to the determination of step S77 until the timeout time is reached. If it is determined in step S77 that the operation has been performed, it is determined whether or not the operation is an operation that permits mode change (step S78). If there is an operation for permitting the mode change in this determination, a command for changing the operation mode of the CS tuner 200 to the normal mode is transmitted (step S80), and the process returns to step S71. When the change to the normal mode is correctly executed, the process from step S71 is performed, so that it is determined in step S74 that the channel selection is successful, and the process proceeds to step S75 where the recording process is started.

  If it is determined in step S81 that the time-out period has been reached, the process proceeds to step S80, where a command for changing the operation mode of the CS tuner 200 to the normal mode is transmitted, and the process returns to step S71. If there is an operation for prohibiting mode change in step S78, it is determined that recording of the program reserved for recording here has failed, and processing for not starting recording is performed (step S79).

  In the example of the flowchart of FIG. 9, the user is inquired about whether or not the mode can be changed, and the mode change is executed when the mode change is permitted by the response and when there is no user operation until timeout. However, if it is determined that the receiving channel is not the designated channel after transmitting the first channel selection command, a command for changing the mode may be sent immediately. That is, as shown in the flowchart of FIG. 10, the controller 121 receives a channel reserved by the CS tuner 200 by transmitting a channel selection command that causes the CS tuner 200 to perform channel switching via the data communication port 137. (Step S71). In this case, before sending the channel selection command, a service switching command (service A, service B switching command) is sent depending on the tuner configuration.

  After sending this channel selection command, the controller 121 of the hard disk recording / reproducing apparatus 100 is currently receiving in order to confirm whether the channel received by the CS tuner 200 is the channel designated by the channel selection command. Is sent to the CS tuner 200 side via the data communication port 137 (step S72). Then, the controller 121 receives a response to the command (step S73). Here, when the reception channel indicated by the received data is the same as the channel specified by the channel selection command, it is determined that the channel selection has succeeded, and the CS tuner 200 determines that the reserved time is reached. A recording process for recording the video signal and the audio signal supplied to the hard disk recording / reproducing apparatus 100 as program data on the hard disk is started (step S75).

  The processing up to this point is the same as the processing in the flowchart of FIG. 9, but in the case of the example of FIG. 10, if it is determined in step S74 that channel selection has not been successful, the mode change command has already been transmitted. (Step S82), and if the mode change command is not transmitted by the determination, the process proceeds to step S84, and a command for changing the operation mode of the CS tuner 200 to the normal mode is transmitted. Return to processing.

  And when it returns to the process of step S71 from step S84, it transfers to step S74 from step S73, and after having transmitted the mode change command of step S82 already when it is judged that channel selection was not successful. If it is determined that the transmission has already been performed, the process proceeds to a recording failure process (step S83). Note that when the mode change command is transmitted in step S84, for example, as shown in FIG. 24, the mode change is forcibly performed as “reserved recording starts and the mode is changed.” Is displayed 1004. By performing the processing as shown in FIG. 10, the priority is given to the reserved recording without inquiring the user whether the mode can be changed.

  Next, contract information processing when there is a recording reservation for the CS channel in the hard disk recording / reproducing apparatus 100 by a user operation or the like will be described with reference to the flowchart of FIG. As described above, with respect to the CS channel, it is determined whether at least a part of the channels or programs are paid channels requiring a subscription contract, and whether or not the channel reserved for recording is a subscription contracted channel. It is. That is, it is first determined whether or not there is a recording reservation (step S101). If there is a recording reservation, the controller 121 of the hard disk recording / reproducing apparatus 100 receives the reception contract information stored in the IC card 213 on the CS tuner 200 side. Is sent to the CS tuner 200 via the data communication port 137 (step S102). Then, it is determined whether or not the controller 121 has received a response to the command (step S103). If a response to the contract information cannot be received, the process returns to step S102.

  If the reception contract information can be received in step S103, it is determined whether or not the received contract channel or contract program includes a channel or program itself for broadcasting the program reserved for recording in step S101 ( Step S104). Here, if it is not a contract channel or contract program, the non-contract is displayed on the screen of the television receiver, and the corresponding recording reservation is canceled (step S105). FIG. 25 shows a display example at this time. In a pop-up display or the like, a warning display 1005 is displayed as “Channel not subscribed. Recording cannot be reserved.”

  If it is determined in step S104 that the channel is a contract channel, the recording reservation at that time is normally received and waited (step S106).

  When the process for acquiring the contract information is performed on the hard disk recording / reproducing apparatus 100 side, the contract information is transmitted on the CS tuner 200 side by the process shown in FIG. That is, when a contract information acquisition command is transmitted from the hard disk recording / reproducing apparatus 100 side (step S111), the controller 210 reads the contract information from the IC card (step S112). Then, it is determined whether or not this reading is successful (step S113), and the process returns to step S112 until it is successful. If it is determined in step S113 that the contract information has been read, the read contract information is transmitted to the hard disk recording / reproducing apparatus 100 side (step S114).

  Next, correction processing of the time counted by the clock unit 124, which is a time measuring unit built in the hard disk recording / reproducing apparatus 100 of this example, will be described with reference to the flowcharts of FIGS. The time counted by the clock unit 124 in this example is periodically corrected under the control of the controller 121. For example, it is corrected once a day at a predetermined time. When the controller 121 determines that the time to be corrected has come (step S121), it sends a command for obtaining time information to the CS tuner 200 side via the data communication port 137 (step S122). It is determined whether or not time information has been returned by the transmission of this command (step S123). If the time information is not returned, the process returns to step S122.

  When the time information is returned in step S123, the time counted by the clock unit 124 is corrected to the time indicated by the returned time information (step S124). The time information sent from the CS tuner 200 at this time is time information added to CS broadcast data (broadcast stream) received by the tuner 200, for example, time information of year / month / day / hour / minute / second.

  Next, the time information transmission processing on the CS tuner 200 side is shown in FIG. 14. When a request for time information is received from the hard disk recording / reproducing apparatus 100 side (step S131), the CS broadcast data received by this tuner is received. Time information added to (broadcast stream) is acquired (step S132). It is determined whether or not time information can be acquired by this acquisition process (step S133). If it cannot be acquired, the process returns to step S132. When the time information can be acquired in step S133, the acquired time information is transmitted to the hard disk recording / reproducing apparatus 100 side (step S134). If the CS tuner 200 also has a clock unit, the time of the clock unit may be corrected at the same time.

  In this way, by correcting the time of the clock of the clock unit 124 in the hard disk recording / reproducing apparatus 100 separate from the CS tuner 200 with the time information added to the broadcast stream, from the hard disk recording / reproducing apparatus 100 side. Even when the recording reservation is executed by this control, the start time and end time of the reserved recording coincide with the time at which the program is broadcast at any time, and accurate recording becomes possible.

  In the above-described embodiment, the example is applied to a recording / reproducing apparatus using a hard disk as a recording medium. However, the present invention may be applied to a recording apparatus using other various recording (storage) media.

  In the above-described embodiment, the tuner built in the recording / reproducing apparatus is a tuner that receives an analog terrestrial television broadcast in the above-described embodiment, but receives a digital terrestrial wave, for example. It may be a tuner of other reception forms such as a tuner. Further, the tuner for receiving the CS broadcast is configured separately from the recording device. However, the tuner for receiving a channel different from the built-in tuner for receiving the CS broadcast is configured with a recording device such as a hard disk recording device. It may be integrated. The tuner for CS broadcast reception may also be a tuner for reception of other broadcast systems such as BS broadcast reception. Or the tuner which receives both CS broadcast and BS broadcast may be sufficient.

  In the above-described embodiment, the video signal and the audio signal converted into the analog signal are transmitted between the separate tuner and the recording / reproducing apparatus. However, the digital video data received by the tuner The audio data may be transmitted to the recording / reproducing apparatus as it is for recording.

  In the above-described embodiment, a separate television receiver is connected to the recording / reproducing apparatus. However, the recording / reproducing apparatus having the processing configuration as in this example may be incorporated in the receiver.

  Also, instead of preparing a dedicated tuner or recording device as in the above example, a large-capacity recording (storage) device equivalent to the recording device in this example is mounted on a personal computer device that performs various data processing, for example. (Connected), and a configuration in which a separate tuner or the like is connected to the computer device, software (program) for controlling EPG data acquisition or broadcast data recording processing is installed in the personal computer device, and the same The video recording process (recording process) may be performed.

  In the above-described embodiment, the case where a general television broadcast is received and recorded has been described as an example. However, for example, recording of other broadcast data such as a radio broadcast and various data broadcasts is performed separately from the reception device. Of course, the same processing may be applied to the case where the recording is performed by a body recording apparatus.
