Description

  The present invention relates to a recording / reproducing apparatus.

In recent years, digital broadcast broadcast programs transmitted from a plurality of broadcast types (eg, terrestrial digital, BS digital, 110 degree CS digital, etc.) have been recorded as copyright protection methods for broadcast programs recorded by users. There are used a method for allowing a program to move only for one generation (copy once method), a method for completely prohibiting copy processing and move processing (copy never method), and the like.
Furthermore, in digital broadcasting, in addition to the above method, the dubbing 10 method (a method that allows nine copy processes and one move process for recorded programs) is started. Is based on which copyright protection method, and how many times the copy process and move process can be executed for the recorded program is a matter of great interest to the user. Before recording, it is desirable to be able to grasp the possible number of copy processing and move processing set for the program.

  As a technique for notifying the user of the possible number of copy processes and move processes, for example, digital information including video information or audio information and copy number information included in the digital information are recorded, and the digital information and the number of copies are recorded. There is known a digital information recording / reproducing apparatus capable of displaying a list of information on an operation screen (see, for example, Patent Document 1).

  However, the copy number information included in the digital information according to the invention described in the above-mentioned Patent Document 1 is used for a program (copy free method), a copy once method, and a copy never method that can be copied and moved without any number of times. The number of times of copying determined based on this is shown. Therefore, depending on the invention described in Patent Document 1, the dubbing 10 system program is not targeted and cannot be identified.

  Furthermore, even if it is possible to identify whether or not the program to be recorded is a program using the dubbing 10 method by the invention described in Patent Document 1, whether or not the dubbing 10 method is used. Can only be grasped after the program to be recorded is broadcast. Further, there is a possibility that the dubbing 10 method, the copy once method, and the like are sequentially switched within the same broadcast program. For this reason, it is difficult to notify the user of the number of times that the copy process or the move process can be performed before the reserved recording of the program.

  On the other hand, for example, in the case of a program that is broadcast based on a certain regularity, such as a plurality of series of broadcast programs (series program), the copyright protection method for each broadcast program is uniform. If the copyright protection method for a broadcast program broadcasted at any time among series programs can be grasped, it is predicted that the program will be set based on specific or regular rules. The copyright protection method for a program can be grasped in advance. Such series programs are mainly recorded continuously by the user at all times. For example, a plurality of broadcast programs can be collectively copied to other recording media in preparation for loss or the like. Since it is conceivable to execute the move process, it is presumed that there is a strong demand for grasping the possible number of copy processes and move processes for broadcast programs to be recorded.

Here, for example, by acquiring an electronic program guide, a video recording apparatus capable of distinguishing between recorded and unrecorded series of a plurality of series of broadcast programs and displaying a list together with titles on the display screen Is known (see, for example, Patent Document 2).
JP 2006-114089 A JP 2007-300412 A

Then, digital broadcast data composed of video data, audio data, and the like is recorded on the disk drive 8 and the recorded digital broadcast data is reproduced.

The tuner unit 3 is a digital tuner configured to include, for example, a high-frequency amplifier circuit, a frequency conversion circuit (not shown) including a local oscillation circuit and a mixing circuit, and the digital broadcast (terrestrial type) of each network (broadcast type). Digital broadcast, BS digital broadcast, 110 degree CS digital broadcast) can be received as digital broadcast data via an antenna or the like. That is, according to the tuner unit 3, digital broadcast data composed of video data, audio data, PSI (Program Specific Information: Program Specific Information) / SI (Service Information: Program Array Information), and local oscillation output from the local oscillation circuit. The signal is mixed by the mixing circuit, and the digital broadcast data of a specific frequency band is received according to the control output from the control unit 14 for selecting the frequency of the digital broadcast data.
The tuner unit 3 converts the received digital broadcast data into an IF (Intermediate Frequency) signal having a predetermined intermediate frequency, and outputs the IF signal to the separation unit 4.
The tuner unit 3 also functions as a broadcast type specifying unit because it outputs a predetermined signal related to the name of the selected network to the CPU 142 when receiving digital broadcast data from a specific network.

Here, the PSI / SI of the digital broadcast data is information including program information (for example, “broadcast channel”, “broadcast station name”, “program name”, “scheduled broadcast date”, etc.) regarding each broadcast program. .
Specifically, the PSI is composed of tables such as PMT (Program Map Table), PAT (Program Association Table), NIT (Network Information Table), CAT (Conditional Access Table), etc. A descriptor for identifying a copyright protection method (for example, a dubbing 10 method, a copy once method, a copy never method, a copy free method) is described.
The SI also includes various tables such as SDT (Service Description Table), EIT (Event Information Table), BAT (Bouquet Association Table), TDT (Time Date Table), and the like.

The separation unit 4 outputs the digital broadcast data which is a broadcast signal to the extraction unit 5, separates the video data and audio data constituting the digital broadcast data from the IF signal input from the tuner unit 3, and separates the separated video data Then, the synchronization signal is separated and output to each part of the apparatus.
Based on this synchronization signal, synchronization is performed when digital broadcast data is recorded and reproduced in the disk drive 8 or the DVD drive 18.

  The extraction unit 5 extracts PSI / SI as program information from the digital broadcast data input from the separation unit 4 based on a control output from the CPU 142 described later, and is recorded in the disk drive 8 or the DVD drive 18. Extraction means for extracting program information from digital broadcast data.

The encoder 6 includes, for example, a video encoder and an audio encoder (not shown).
The video encoder compresses video data constituting the digital broadcast data according to the MPEG (Motion Picture Expert Group) system, and the audio encoder compresses audio data constituting the digital broadcast data according to the MPEG audio system.
The digital broadcast data generated by the encoder 6 is output to the disk drive 8 or the DVD drive 18 via the data processor 7.

The data processor 7 sets an input / output path for digital broadcast data based on a control output from the CPU 142, which will be described later, and controls data input and output.
Specifically, for example, when a recording instruction is given to the disk drive 8 or the DVD drive 18 by the operation of the remote controller 2 by the user, the digital broadcast data input from the encoder 6 is transferred to the disk drive 8 or the DVD drive 18. Output to.

The disk drive 8 (recording unit) is a magnetic disk drive compliant with the ARIB (Association of Radio Industries and Broadcast) standard, and records received digital broadcast data in accordance with the recording operation of the user's remote control unit 2, for example, A built-in hard disk (not shown), a magnetic head (not shown) for storing data in the hard disk or reading data stored in the hard disk, rotating the hard disk and moving the magnetic head in the radial direction of the hard disk A drive unit (not shown) for movement is provided. A hard disk includes a non-magnetic disk substrate (not shown) and a magnetic layer (not shown) provided thereon, and a magnetic field is supplied by supplying a current between the magnetic head and the hard disk. Has a small gap.
Further, the disk drive 8 stores history information (for example, information such as recording date and time, number of times of copy processing (dubbing), etc.) for each recorded digital broadcast data. Furthermore, the history information includes “viewing presence / absence” (reproduction presence / absence information) indicating whether or not each digital broadcast data has been reproduced via the decoder 10 and the output interface unit 11 as a reproduction unit.

For example, the decoder 10 includes a video decoder, an audio decoder, and the like, although not shown.
The video decoder restores video data according to the MPEG system, and the audio decoder restores audio data according to the MPEG audio system.
The digital broadcast data generated by the decoder 10 is output to the output interface unit 11 in the reproduction process.

The output interface unit 11 includes, for example, a video output unit 11a, an audio output unit 11b, a D / A converter (not shown), and the like, and performs various output interface processes for digital broadcast data input from the decoder 10 in the reproduction process. Are converted into video data and audio data suitable for the television receiver 200 of the NTSC system or the PAL system. Specifically, the D / A converter converts the digital broadcast data input from the decoder 10 into analog data when the output is analog.
Video and audio, which are information based on the digital broadcast data generated in the output interface unit 11, are respectively output to the display screen 200 a and the speaker (not shown) of the television receiver 200 connected to the HDD recorder 1. Therefore, the output interface unit 11 functions as a reproducing unit together with the decoder 10.
Note that the output interface unit 11 may output video data and audio data through the same HDMI cable as an interface having a terminal compliant with the HDMI (High Definition Multimedia Interface) standard together with the television receiver 200. .

  The OSD circuit 12 performs a process of synthesizing OSD data (not shown) stored in the ROM 144 with the video data constituting the digital broadcast data.

The remote control unit 2 is, for example, a remote control device (remote control) that performs a remote operation on the HDD recorder 1, and a “record button” for recording digital broadcast data on the disk drive 8 and the recorded digital broadcast data And the like, and a predetermined input operation signal is transmitted to the remote control signal light receiving unit 13 in response to pressing of each button or key. Further, the remote control unit 2 includes blue, red, green, and yellow color buttons, a “cursor button” that moves the cursor up and down or left and right on the display screen 200a of the television receiver 200, and a user's remote control unit 2 A “decision” key for reflecting a predetermined operation result, a “menu” key for calling / ending the menu screen, a “return” key for switching the previous screen display of the screen displayed on the display screen 200a, and the like. , Etc., and the buttons / keys exhibit different pressing functions depending on the screen displayed on the display screen 200a of the television receiver 200.
That is, a button / key function table (not shown) in which each display screen is associated with the function of each button / key on the display screen is stored in the ROM 144, and the CPU 142 receives the remote control unit via the remote control signal light receiving unit 13. When an input operation signal from 2 is input, control is performed to execute input operation processing corresponding to the screen displayed on the display screen 200a and the type of button / key input by the user. The function of the button / key corresponding to the screen displayed on the display screen 200a is notified to the user by the button / key function explanation section 500a to 510a of each screen.

  When various buttons / keys provided on the remote control unit 2 are pressed by the user, the remote control signal light receiving unit 13 receives an input operation signal such as an infrared ray output from the remote control unit 2 and sends the input operation signal to the CPU 142. Output.

  The control unit 14 includes a CPU (Central Processing Unit) 142, a storage unit 143, a ROM (Read Only Memory) 144, and the like.

  The CPU 142 stores in the ROM 144 in accordance with input signals input via the respective units of the HDD recorder 1 and input operation signals input via the remote control signal light receiving unit 13 by pressing various keys of the remote control unit 2. In addition to executing the various programs, the overall operation of the HDD recorder 1 is comprehensively controlled by outputting an output signal to each part of the apparatus based on the program for execution.

The storage unit 143 stores a program storage area (not shown) for developing a processing program executed by the CPU 142, and a data storage area (not shown) for storing processing results generated when the input data and the processing program are executed. (Omitted).
In addition, the storage unit 143 includes a non-volatile memory that can update the stored contents and can retain the stored contents even when the power is turned off, such as an NVRAM (Non Volatile Random Access Memory).
The storage unit 143 is executed by executing a table 145 stored by execution of a series program storage program 144b, which will be described later, a series table 146 created by execution of the series table creation program 144h, and a confirmation channel table creation program 144o. A confirmation channel table 147 to be created.

  A ROM (Read Only Memory) 144 is composed of, for example, a non-volatile memory, and has a data storage area and a program storage area for storing OSD data related to OSD display displayed on the display screen 200a of the television receiver 200. The storage area includes a series program information search program 144a, a series program storage program 144b, a reception program 144c, a determination program 144d, a recorded series program information determination program 144e, a copy processing number calculation program 144f, and a copy remaining number. A number calculation program 144g, a series table creation program 144h, a list display control program 144i, a broadcast list display control program 144j, a recording list display control program 144k, Talk list display control program 144l, confirmation channel list display control program 144m, pay channel list display control program 144n, confirmation channel table creation program 144o, specific program 144p, time determination program 144q, and coincidence determination program 144r Description of various programs such as message display program 144s and determination program 144t, broadcast channels for each network, broadcast station names corresponding to the broadcast channels, and whether or not the channels are pay channels The broadcast channel list data (not shown) is stored.

The series program information search program 144a is series program information search means for searching for series program information from the program information extracted by the extraction unit 5.
That is, by executing the series program information search program 144a, the CPU 142 executes a confirmation channel list display control program 144m or a pay channel list display control program 144n, which will be described later, to the broadcast station (broadcast channel) selected by the user. The program information is extracted by the extraction unit 5 and only the information of the broadcast scheduled program including the series program information is searched. Specifically, when the broadcast-scheduled program is a series program, the SI of the program information of the broadcast-scheduled program includes series program information (for example, “series descriptor”, “broadcast channel”, “ It consists of data such as “Broadcasting station name”, “Series program name”, “Title” indicating the title of each story, “Number of stories”, “Broadcast scheduled date and time”, “End time” indicating the scheduled broadcast end date of the series program Therefore, the CPU 142 executes the series program information search program 144a and causes the program information to search for a broadcast-scheduled program having a series descriptor, thereby obtaining one or more series program information. Search for.
In addition, since the program information has a period during which update information is transmitted by the broadcast channel (usually about eight days), the CPU 142 executes the series program information search program 144a every time that period elapses. Therefore, the latest program information is always acquired.

The series program storage program 144b associates the series program information searched by the series program information search program 144a with the network name (broadcast type name) of the network (broadcast type) to be searched and stores it in a table format. I can do it.
That is, by executing the series program storage program 144b, the CPU 142 executes predetermined program information such as the network name of the network that transmits the series program information searched by the series program information search program 144a and the digital broadcast data including the series program information. Is stored in the storage unit 143.
Here, the network name can be obtained by receiving a predetermined signal output from the tuner unit 3 serving as a broadcast type specifying means each time series program information is searched by the series program information search program 144a. .
In addition, the table 145 includes “network name”, “broadcast channel”, “broadcast station name”, “series program name”, “title”, “number of stories” as shown in FIG. , “Broadcast scheduled date / time”, “End time”, “Recorded date” as recorded information, “Viewing”, “Protection method (confirmation)”, “Protection method (method name)” as protection method information, dubbing processing The series program storage program 144b functions as series program information storage means and protection method information storage means because it is composed of data items such as “remaining number of copy processes” as possible number of times.
Note that “recording date” and “viewing” in the table 145 are described by execution of a recorded series program information determination program 144e described later, and “protection method (confirmation)” and “protection method (method name)” are described later. The “copy processable remaining number” is described by the execution of a later-described determination program 144d and a copy remaining number calculation program 144g.

The reception program 144c is reception means for receiving digital broadcast data corresponding to the series program information stored in the table 145.
That is, by executing the reception program 144c, the CPU 142 changes the network and channel to match the “network name” and “broadcast channel” of the series program information stored by the execution of the series program storage program 144b. The digital broadcast data can be received until the end of the broadcast of the digital broadcast data.

The determination program 144d is determination means for determining the copyright protection method of the digital broadcast data received by the reception program 144c.
That is, by executing the determination program 144d, the CPU 142 extracts the PMT (PSI) of the digital broadcast data received by the reception program 144c by the extraction unit 5, and identifies the copyright protection method in the extracted PMT. It is a determination means for determining which copyright protection method is used from the descriptor. Since the received digital broadcasting data may have a different copyright protection method for each scene or time zone, when the CPU 142 executes the determination program 144d, the reception program 144c While digital broadcast data is being received, the copyright protection method is continuously determined.
In the determination of the copyright protection method, a copy determined for each copyright protection method of the copyright protection method determined so far and the newly determined copyright protection method. The maximum value that can be processed (for example, 9 times in the case of dubbing 10 method) is compared, and of the two, the one with the smaller maximum value (that is, the one with more severe dubbing conditions for the user) It will be updated as a copyright protection method for digital broadcasting data.
Therefore, “protection method (method name)” in the table 145 of the storage unit 143 is described as “completed” in the “protection method (confirmation)” column by the execution of the determination program 144d and finally updated. The copyright protection method that has been set is described.
The CPU 142 executes the determination program 144d to determine the copyright protection method of the digital broadcast data, and the maximum value that can be executed for the copy process defined for the copyright protection method is shown in the table 145. It also functions as a generating means described as an initial value of “the number of remaining copy processes”.

The recorded series program information discriminating program 144e is a program for discriminating whether or not the digital broadcast data including the series program information stored in the table 145 is recorded in the disk drive 8.
That is, the CPU 142 executes the recorded series program information search program 144e to extract the acquisition of the series program information (extraction of the series descriptor) from the SI of the program information of the digital broadcast data recorded in the disk drive 8. It functions as acquisition means to be executed by the unit 5.
Further, when the series program information can be extracted by executing the recorded series program information search program 144e, the CPU 142 detects the series program information that matches the series program information of the digital broadcast data from the table 145, and detects the series program information. The recording date / time (history information) of the digital broadcast data stored in the disk drive 8 is described in the “recording date” of the information, and the presence / absence of viewing (history information) in “viewing” is “ "Completed" and "Uncompleted" if not viewed). Therefore, the recorded series program information search program 144e functions as an acquisition unit and a reproduction presence / absence information storage unit.

The copy processing count calculation program 144f is a program for calculating the number of times that the copy processing has been performed by executing the copy processing program 144z for each digital broadcast data stored in the disk drive 8.
That is, when the user selects the copy process for the digital broadcast data stored in the disk drive 8 by operating the remote control unit 2, the copy process program 144z of the CPU 142 executes the copy process for the recording medium of the DVD drive 18. When the copy process is performed, the copy process count calculation program 144f is executed to update the history information stored in the disk drive 8 for the digital broadcast data, that is, increase the number of times the copy process has been performed.

In the copy remaining number calculation program 144g, the copyright protection system is determined by the determination program 144d, and the digital broadcast data including the series program information stored in the table 145 is stored in the disk drive by the recorded series program information determination program 144e. 8 is a program for calculating the remaining number that can execute the copy processing of the digital broadcast data when it is determined that the digital broadcast data is recorded.
That is, when the CPU 142 executes the copy remaining number calculation program 144g, the series program information stored in the table 145, with the date described in the “recording date” and “completed” in the “protection method (confirmation)” is displayed. For the digital broadcast data provided, every time history information (the number of times of copy processing) is updated by execution of the copy processing number calculation program 144f from the “copy processing remaining number” described in the table 145 by execution of the determination program 144d. In order to calculate the remaining number that can be copied by subtracting the number of times the copy process has been performed, and to update and describe the calculated remaining number that can be copied in the “remaining number that can be copied” in the table 145 Is functioning as

The series table creation program 144h is a program that aggregates series program information of each story having the same series program name based on the table 145, and stores it in the storage unit 143 as a series table 146.
That is, when the CPU 142 executes the series table creation program 144h, the series program information of each story stored in the table 145 is unified for each series program as a series table 146 as shown in FIG. I can remember.
Here, each column of “network name”, “broadcast channel”, “broadcast station name”, “series program name”, and “end time” for each series program in the series table 146 is a series program stored in the table 145. Information common to the series program information of each story having the same name (hereinafter referred to as the same series program) is described. However, if the end time of the series described in “End Time” is before the current date and time counted by the time measuring unit 16, “End” is described.
Next, as for “reservation status”, the CPU 142 executes a list display control program 144i to be described later to display a series program list screen 500, and the user sets a batch reservation setting for all episodes for a predetermined series program via the remote control unit 2. Will be marked as “Reserved”.
Next, the “number of stories” is compared with the current date and time counted by the timer unit 16 and the “scheduled broadcast date and time” of the series program information of each story of the same series program stored in the table 145, and immediately before the current date and time. The “number of stories” having “scheduled broadcast date and time” (that is, the total number of stories of the series program broadcast up to the current date and time) is retrieved and described.
Next, “protection method (confirmation)” is one in which “completed” is described in “protection method (confirmation)” of the series program information of each story of the same series program stored in the table 145. If there is, it is described as “done”, and if there is no “done”, it is described as “unconfirmed”.
Next, “protection method (method name)” describes the name of the method when the “protection method (method name)” of the series program information of each story of the same series program stored in the table 145 is the same. However, if there is even one different thing, it is described as “mixed”. However, nothing is described for a series program in which “protection method (confirmation)” is described as “unconfirmed”.
Next, the “scheduled date and time of next broadcast” compares the current date and time counted by the time counting unit 16 with the “scheduled date and time of broadcast” of the series program information of each episode of the same series program stored in the table 145, "Broadcast scheduled date and time" (that is, the scheduled broadcast date and time of the next episode of the series program) is described.
Next, “recording status” includes “end time” described as “end time” and all “recording dates” described for all series program information of the same series program stored in the table 145. If it is, write “All episodes recorded”. And about all the series program information of the same series program memorize | stored in the table 145, when "end time" is not described as "end" and all the "recording dates" are described, or Regarding all the series program information of the same series program stored in the table 145, “End time” is described as “End”, and “Recording date” is described as not being described. When mixed, “recording status” is described as “partially recorded”. In other cases, the “recording status” is blank.

The list display control program 144i is a program that displays predetermined information about each series program as a list on the display screen 200a via the television receiver 200 for each network based on the series table 146.
That is, by executing the list display control program 144i, the CPU 142 uses the series table 146 and, for example, as shown in FIG. 4, the series program list screen 500 (for example, the network is BS, and the subsequent screens are also displayed. Similarly, the list is displayed on the display screen 200a of the television receiver 200. Then, as displayed on the button / key function explanation unit 500a, the CPU 142 executes the list display control program 144i in accordance with a predetermined operation of the remote control unit 2, and display switching for each network is possible. Therefore, the list display control program 144i functions as list display control means.
Items “CH No”, “reservation status”, “series program name”, “number of stories”, “protection method (confirmation)”, “protection method (confirmation)” of each list (each series program) displayed on this series program list screen 500 The “protection method (method name)”, “end time”, “scheduled next broadcast date”, and “recording status” are “broadcast channel” and “broadcast channel” of the series program whose “network name” is BS in the series table 146, respectively. “Reservation status”, “Series program name”, “Number of stories”, “Protection method (confirmation)”, “Protection method (method name)”, “End time”, “Date and time of next scheduled broadcast”, “ What is recorded in “Recording Status” is displayed.

The in-broadcast list display control program 144j performs predetermined information on the series program currently being broadcast in response to an operation of the remote control unit 2 in a state where the series program list screen 500 is displayed on the display screen 200a of the television receiver 200. Are controlled on the display screen 200a.
That is, the CPU 142 allows the user to use the “yellow button” of the remote control unit 2 so that the series program list screen 500 is displayed on the display screen 200a of the television receiver 200 and displayed on the button / key function explanation unit 500a. Is pressed and the input operation signal is received, the broadcast list display control program 144j is executed. For example, as shown in the broadcast series program list screen 501 of FIG. 5, each series program on the series program list screen 500 is displayed. The series program described as “End” in “End Time” is omitted, and the list is redrawn.
Therefore, the number of lists becomes enormous, the display becomes complicated, and it can be said that this is an effective display limiting method when the user wants to know only information related to a series program currently being broadcast.

The recording list display control program 144k is a recording target in accordance with the operation of the remote control unit 2 in a state where the series program list screen 500 or the broadcasting series program list screen 501 is displayed on the display screen 200a of the television receiver 200. Predetermined information about the current series program is displayed as a list on the display screen 200a.
In other words, the CPU 142 displays the series program list screen 500 or the broadcasting series program list screen 501 on the display screen 200a of the television receiver 200 so as to be displayed on the button / key function explanation units 500a and 501a. When the user presses the “red button” on the remote control unit 2 and receives the input operation signal, for example, as shown in the series program recording list screen 502 of FIG. Since the “recording status” of each series program is displayed as a list from which blank series programs are omitted from the screen 501, the user can grasp only information related to the series programs to be recorded.
In the series program recording list screen 502, items of “reservation status”, “protection method (confirmation)”, and “end time” are omitted from the list display items of the series program list screen 500 or the series program list screen 501 being broadcast. In order to improve the usability, a minimum configuration for grasping the recording state of the series program is adopted.

Each talk list display control program 144l displays one of a series program list screen 500, a series program list screen 501 being broadcast, and a series program recording list screen 502 on the display screen 200a of the television receiver 200. In a state where a predetermined series program is selected, predetermined information about each story of the currently broadcast series program is displayed and controlled on the display screen 200a in accordance with the operation of the remote controller 2.
That is, the CPU 142 selects the “green button” of the remote control unit 2 so that the user selects a predetermined series program while any one of the screens is displayed and is displayed on the button / key function explanation units 500a, 501a, and 502a. When the input operation signal is received, the series program information having the same series program name as the series program selected by the user is displayed as shown in the series program recording status display screen 504 of FIG. The recording status of each story of the selected series program retrieved from the table 145 is displayed as a list.
Here, the items “title”, “story”, “protection method”, “recording date”, “viewing”, and “dubbing remaining number” of each list (each story) on the series program recording status display screen 504 are respectively stored in the table 145. Are displayed in the columns of “title”, “number of stories”, “protection method (method name)”, “recording date”, “viewing”, “remaining number of copy processes”.
Further, when the user operates the remote controller 2 while the series program recording status display screen 504 of FIG. 7 is displayed, the CPU 142 selects each story list display control program. By executing 144l, as shown in the dubbing / move operation screen 504b in FIG. 8, regarding the number of stories, the user is notified of the dubbing remaining number (copy processing remaining number), and dubbing (copying process) or moving operation ( A screen for selecting the execution of the move process can be displayed.

The confirmation channel list display control program 144m is a state in which any one of the series program list screen 500, the series program list screen 501 being broadcast, and the series program recording list screen 502 is displayed on the display screen 200a of the television receiver 200. Then, “CH No” (broadcast channel) and “broadcast station name” are displayed as a list on the display screen 200a in accordance with the operation of the remote control unit 2.
That is, the CPU 142 allows the user of the remote control unit 2 to display the button / key function explanation units 500a, 501a, and 502a in a state where any of the above screens is displayed on the display screen 200a of the television receiver 200. When the “blue button” is pressed to receive the input operation signal, broadcast channel list data stored in the ROM 144 can be displayed as a list, for example, as shown in a channel list screen 505 in FIG.
Then, when the channel list screen 505 is displayed, the user selects a predetermined broadcast channel and presses the “decision button” on the remote control unit 2, thereby displaying the series program confirmation channel selection screen 506 of FIG. 10. The selected broadcast channel can be selected as a broadcast channel (series program confirmation channel) for confirming whether or not a series program exists, and the series program information search program 144a searches for the series program information. Broadcast channel. Therefore, the confirmation channel list display control program 144m functions as a broadcast channel selection unit.
Furthermore, when the user selects a predetermined broadcast channel as the series program confirmation channel on the series program confirmation channel selection screen 506 in FIG. 10, the protection method confirmation channel selection screen 507 in FIG. By pressing the “button”, it is possible to confirm the copyright protection method for the series program broadcast on the selected broadcast channel (protection method confirmation channel).

The pay channel list display control program 144n displays “CH No” (for a pay channel in response to an operation of the remote control unit 2 in a state where the channel list screen 506 is displayed on the display screen 200a of the television receiver 200. Broadcast channel) and “Broadcasting station name” are displayed in a list on the display screen 200a.
That is, the CPU 142 executes the confirmation channel list display control program 144m, and the user displays the channel list screen 506 of FIG. 10 on the display screen 200a of the television receiver 200 and the user presses the “red button” of the remote control unit 2. When the input operation signal is received by pressing, for example, as shown in the pay channel list screen 508 in FIG. 12, only the pay channels are displayed as a list based on the broadcast channel list data stored in the ROM 144. I can do it.
Then, as in the case where the confirmation channel list display control program 144m is executed in a state where the pay channel list screen 508 is displayed, the series program confirmation channel selection screen 509 shown in FIG. It is possible to select a broadcast channel for checking whether or not it exists, and a protection method confirmation channel selection screen 510 shown in FIG. 14 is displayed, and a copyright protection method is set for a series program broadcast on the selected broadcast channel. You can select whether to confirm. Therefore, the pay channel list display control program 144n functions as a broadcast channel selection unit.
Therefore, a list of channels for only pay channels that are likely to adopt different copyright protection methods for each series program is displayed and the above selection can be made, so that the usability can be further improved. I can do it.

The confirmation channel table creation program 144o is a program that creates the confirmation channel table 147 and stores it in the storage unit 143.
That is, the CPU 142 executes the confirmation channel list display control program 144m and / or the pay channel list display control program 144n, and selects information indicating that a predetermined broadcast channel is selected as the series program confirmation channel and / or the protection method confirmation channel. By executing the creation program 144o, it can be stored in the storage unit 143 as a confirmation channel table 147 as shown in FIG.
Here, as shown in FIG. 15, the confirmation channel table 147 includes data items of “network name”, “broadcast channel”, “series program confirmation channel”, “next update date”, and “protection method confirmation channel”. Is done.
First, “network name” and “broadcast channel” are described based on broadcast channel list data stored in the ROM 144.
Then, the “series program confirmation channel” and the “protection method confirmation channel” indicate that the “broadcast channel” is changed to the series program confirmation channel and the channel confirmation display program 144m and / or the pay channel list display control program 144n of the CPU 142. When the channel is selected as a protection method confirmation channel, “target” is described.
Next, the “next update date” is the date when the CPU 142 executes the series program information search program 144a for the broadcast channel whose “series program confirmation channel” is described as “target” (that is, the program defined for the broadcast channel). (Date of information transmission) describes a date obtained by adding a predetermined period (usually about eight days) until the program information is updated.

The specifying program 144p is a broadcast channel specifying means for specifying the network currently selected by the user and the selected broadcast channel.
That is, when the CPU 142 executes the specific program 144p, it receives a predetermined output signal related to the currently selected network and the selected broadcast channel from the tuner unit 3, thereby selecting the current user. Network and the selected broadcast channel can be specified.

The time determination program 144q determines whether or not the current time measured by the timer unit 16 is a predetermined time before the “broadcast scheduled date and time” of the predetermined series program information stored in the series table 145. It is.
That is, the CPU 142 executes the time determination program 144q to extract the “broadcast scheduled date and time” of the predetermined series program information stored in the series table 145, and the current time measured by the time measuring unit 16 is the broadcast time. It is determined whether or not a predetermined time (eg, 10 minutes) before the scheduled date and time.

The coincidence determination program 144r, when it is determined by the time determination program 144q that it is a predetermined time ago, the network name and broadcast channel of the network specified by the specification program 144p and the predetermined series stored in the series table 145 It is a coincidence judging means for judging whether or not “network name” and “broadcast channel” of the program information coincide.
That is, the CPU 142 executes the match determination program 144r, whereby the network name of the network currently selected by the user and the broadcast channel selected (viewed) are stored in the series table 145. It can be determined whether the “network name” and “broadcast channel” of the series program information match.
If the CPU 142 determines that they match, the receiving program 144c receives the digital broadcast data of the series program. If it determines that they do not match, the message display program 144s (or determination program) described later is received. 144t).

The message display program 144s prompts the user to select a network of a predetermined series program stored in the series table 145 and prompt the user to select a broadcast channel when it is determined by the match determination program 144r that they do not match. These are display control means for displaying on the display screen 200a of the television receiver 200.
In other words, when the CPU 142 determines that they do not match by the match determination program 144r, when the message display program 144s is executed, the user is asked to confirm the copyright protection method as in the message display screen shown in FIG. It functions as a display means for displaying a message for prompting selection of a network of a predetermined series program and selection of a broadcast channel on the display screen 200a of the television receiver 200 for a predetermined time. When the user selects a network of a predetermined series program and selects a broadcast channel within a predetermined time, the CPU 142 executes the reception program 144c and receives digital broadcast data of the series program.
The message display program 144s may display the second message display screen of FIG. 17 or the third message display screen of FIG. 18 by executing a determination program 144t described later.

The determination program 144t displays the second message display screen of FIG. 17 or the third message display screen of FIG. 18 by executing the message display program 144s, and determines whether the user selects a network and selects a broadcast channel. It is a determination means for determining whether or not.
That is, when the CPU 142 executes the determination program 144t, the message display program 144s is executed to display a message as shown in the second message display screen of FIG. 17 or the third message display screen of FIG. Therefore, the user can determine whether or not to select a network of a predetermined series program and select a broadcast channel through the operation of the remote control unit 2.
When the CPU 142 determines that the user selects a network of a predetermined series program and selects a broadcast channel by executing the determination program 144t, the CPU 142 switches to the network and the broadcast channel via the tuner unit 3. Therefore, the digital broadcast data of the series program can be received by the reception program 144c.

The copy processing program 144z is a program for copying the digital broadcast data recorded on the disk drive 8 to the recording medium of the DVD drive 18.
That is, when the copy processing program 144z is executed, the CPU 142 functions as a dubbing processing means for copying (dubbing) the digital broadcast data recorded in the disk drive 8 to the DVD loaded in the DVD drive 18.

  The timer unit 16 measures the current time and outputs the measured current time data to the CPU 142 according to the control output from the CPU 142.

The DVD drive 18 is loaded in the DVD drive 18, for example, although not shown, a DVD that is detachable from the DVD drive 18, an optical pickup that records data on the DVD and reads data recorded on the DVD, and the like. And a drive unit for rotating the optical DVD and moving the optical pickup in the radial direction of the DVD.
Specifically, the DVD is a rewritable disc such as a write-once disc such as a DVD-R (DVD-Recordable) or a DVD-RW (DVD-ReWriteable) or a DVD-RAM (DVD-Random Access Memory). .
In this DVD drive 18, in recording processing and copying processing, a laser beam is irradiated to the reflective layer of the DVD by an optical pickup, and the crystal structure of the recording layer is changed by heating with the reflected light to form pits. Write data to. That is, the DVD drive 18 writes the digital broadcast data received via the tuner unit 3 or the like or the digital broadcast data recorded on the disk drive 8 on the DVD and records it.
Further, in the DVD drive 18, in the reproduction process and the copy process, the DVD reflection layer is irradiated with laser light by an optical pickup, and a voltage signal corresponding to the reflected light is generated by photoelectric conversion and current-voltage conversion. The recorded digital broadcast data is read out.

  The television receiver 200 includes a display screen 200a as a liquid crystal display screen and a speaker (not shown), and performs digital broadcasting based on video / audio data of digital broadcasting data input via the output interface unit 11. Video / audio can be output through the display screen 200a or a speaker.

<Confirmation channel setting process>
Next, the series program confirmation channel and protection method confirmation channel setting process in the HDD recorder 1 will be described with reference to the flowchart of FIG.

  First, it is assumed that the CPU 142 executes the confirmation channel list display control program 144m, and the channel list screen 505 is displayed on the display screen 200a of the television receiver 200 (step S1).

Next, when the “red button” of the remote controller 2 is pressed by the user while the channel list screen 505 is displayed (step S2; Yes), when the input operation signal is input to the CPU 142, the CPU 142 The pay channel list display control program 144n is executed, the pay channel list screen 508 is displayed on the display screen 200a of the television receiver 200 (step S3), and the process proceeds to A1 in FIG.
On the other hand, when the channel list screen 505 is displayed and the “red button” of the remote control unit 2 is not pressed by the user (step S2; No), the process proceeds to A1 in FIG.

  In A1, when the user operates the remote controller 2 to select a predetermined channel from the broadcast channels displayed on the channel list screen 505 or the pay channel list screen 508 (step S4; Yes), the confirmation channel list of the CPU 142 By executing the display control program 144m or the pay channel list display control program 144n, the series program confirmation channel selection screens 506 and 509 are displayed on the display screen 200a of the television receiver 200 (step S5).

  Next, when the user selects the predetermined channel selected in step S5 as a series program confirmation channel (step S6; Yes), the confirmation channel list display control program 144m or the pay channel list display control program 144n of the CPU 142 executes Protection method confirmation channel selection screens 507 and 510 are displayed on the display screen 200a of the television receiver 200 (step S7; Yes). On the other hand, when the user does not select the predetermined channel selected in step S5 as the series program confirmation channel (step S6; No), the process returns to step S4.

  Next, when the protection method confirmation channel selection screens 507 and 510 are displayed in step S7, when the user further selects the broadcast channel selected as the series program confirmation channel in step S6; Yes as the protection method confirmation channel (step S8; Yes) On the channel list screen 505 or the pay channel list screen 508, “Select” is displayed in the “Confirm Series Program” and “Confirm Protection Method” of the selected broadcast channel, and the broadcast channel is selected. The state is updated (step S9), and the process returns to step S4. On the other hand, when the protection method confirmation channel selection screens 507 and 510 are displayed in step S7, the user does not select the broadcast channel selected in step S6; Yes as the protection method confirmation channel (step S8; No) On the channel list screen 505 or the pay channel list screen 508, only “confirm series program” of the selected broadcast channel is displayed as “selected”, and the selection state of the broadcast channel is updated (step S10). Return to step S4.

  In step S4, if no channel is selected from the broadcast channels displayed on the channel list screen 505 or the pay channel list screen 508 (step S4; No), the pay channel list is displayed on the display screen 200a of the television receiver 200. When the screen 508 is displayed (step S11; Yes), the process proceeds to A2, and when it is not the pay channel list screen 508 (that is, when the channel list screen 505 is displayed), the process proceeds to A3.

In A <b> 2, that is, when the pay channel list screen 508 is displayed on the display screen 200 a of the television receiver 200, the user does not exit the pay channel list screen 508 (continues setting of the confirmation channel for the pay channel). Shifts to A1 again (step S12; No).
On the other hand, when the user presses the “return” button on the remote controller 2 to end the paid channel list screen 508 (step S12; Yes) and returns to the channel list screen 505, the CPU 142 displays the confirmation channel list display control program 144m. And return to step S2 (step S13; No).
Further, in A2, when the user terminates both the pay channel list screen 508 and the channel list screen 505 by pressing the “menu” button on the remote control unit 2, the CPU 142 executes the confirmation channel table creation program 144o to confirm The description of the channel table 147 is updated based on the setting information of the series program confirmation channel and the protection method confirmation channel displayed on the channel list screen 505 or the pay channel list screen 508 (step S14).

In A3, that is, in a state where the channel list screen 505 is displayed on the display screen 200a of the television receiver 200, the user does not end the channel list screen 505 (the setting of the confirmation channel for the broadcast channel is continued). Then, the process proceeds to A1 again (step S15; No). On the other hand, when the user ends the channel list screen 505 by pressing the “menu” button on the remote control unit 2, the process proceeds to step S14.
As described above, in the HDD recorder 1, the setting of the channel for confirming whether or not the series program exists and the setting of the channel for confirming the copyright protection method are performed.

<Series program information search update processing>
Next, the series program information search / update process in the HDD recorder 1 will be described with reference to the flowchart of FIG.

  First, at a predetermined date and time when the HDD recorder 1 is in the standby state, the CPU 142 refers to the confirmation channel table 147 and refers to the next update date of each series program confirmation channel and the current date timed by the time measuring unit 16. Comparison is performed (step S101).

  Next, in step S101, when the CPU 142 can search for a series program confirmation channel whose next update date is before the current date (including those for which the next update date is not filled in) (step S102; Yes), the CPU 142 The program information search program 144a is executed, the program information of the corresponding broadcast channel (series program confirmation channel) is acquired via the tuner unit 3 (step S103), and all the series program information in the series program confirmation channel is retrieved (step S103). Step S104).

  Next, when one or more series program information can be retrieved in step S104 (step S105; Yes), the CPU 142 additionally stores the retrieved series program information in the table 145 by executing the series program storage program 144b. (Step S106) Further, by executing the series table creation program 144h, the series table 146 is updated and stored (Step S106).

Next, if the table 145 and the series table 146 are updated in step S106, and if the series program information cannot be retrieved in step S104 (step S105; No), the next time for all the series program confirmation channels, It is determined whether or not it is confirmed whether or not the update date is before the current date (step S107). When there is a series program confirmation channel that has not been confirmed, the process returns to step S102 (step S107; No), and the processes from S102 to S107 are repeated. On the other hand, if the above confirmation has been made for all the series program confirmation channels (step S107; Yes), the series program information search / update process ends.
Therefore, since the table 145 and the series table 146 are updated by the above processing, when the CPU 142 executes the list display control program 144i, the list of the latest series programs can be displayed on the series program list screen 500. .

<Copyright protection method confirmation process>
Next, the copyright protection method confirmation processing of the series program in the HDD recorder 1 will be described with reference to the flowchart of FIG.

  First, the CPU 142 refers to the series table 146 and the confirmation channel table 147 (step S501).

  Next, the CPU 142 executes the time determination program 144q, so that the “next broadcast scheduled date and time” of the predetermined series program in the series table 146 referred to in step S501 is based on the current date and time counted by the timing unit 16. It is determined whether or not it is a predetermined time ago, and the “broadcast channel” of the series program is described as the “protection method (target)” target in the confirmation channel table 147 (that is, the protection method confirmation channel) It is determined whether or not (step S502).

If the series program satisfies the condition of step S502 (step S502; Yes), it is determined whether the HDD recorder 1 is in a standby state (step S503).
If the HDD recorder 1 is in the standby state (step S503; Yes), the process proceeds to B1.

  On the other hand, when the series program does not satisfy the condition of step S502 (step S502; No), the process proceeds to step S505.

  If the HDD recorder 1 is not in the standby state (step S503; No), the CPU 142 executes the match determination program 144r, and the user currently views (selects) the broadcast channel of the predetermined series program determined in step S502. It is determined whether or not (station S) (step S504). When the CPU 142 determines that the user is currently viewing (channel selection) (step S504; Yes), the CPU 142 proceeds to B1, while determining that the user is selecting a different channel. (Step S504; No), the process proceeds to B2.

  When the processing of B1 and B2 is completed, or when the condition of step S502 is not satisfied (step S502; No), confirmation of step S502 has been made for all the series programs described in the series table 146. If there is an unconfirmed series program (step S505; No), a different series program is extracted from the series table 146 and the processing from S502 is repeated, and all the series programs are confirmed ( Step S505; Yes), the copyright protection method confirmation process is terminated.

(About B1 processing)
In B1, as shown in FIG. 23, confirmation processing of the copyright protection method of the predetermined series program determined in step S502 is performed.
That is, in step S601, the CPU 142 executes the reception program 144c to start reception of the predetermined series program (digital broadcast data) determined in step S502 (step S601).
When the CPU 142 executes the determination program 144d and a predetermined series program is received in step S601, the copyright protection method is determined (step S602).
Then, the CPU 142 determines whether or not the reception of the predetermined series program has been completed (step S603), and when it has not been completed (step S603; No), the processing after step S602 is repeatedly executed.
On the other hand, if the CPU 142 determines that the reception has been completed (step S603; Yes), the columns “protection method (method name)” and “protection method (confirmation)” in the table 145 are updated, and further a series table creation program 144h is executed to update the series table 146 (step S604).

(About B2 processing)
In B2, as shown in FIG. 24, when the user selects a channel different from the broadcast channel of the predetermined series program determined in step S502, the user selects the broadcast channel of the series program. The process which prompts to do is performed.
That is, the CPU 142 executes the message display program 144s, and as shown in FIG. 24, in order to confirm the copyright protection method on the display screen 200a of the television receiver 200, the network selection of a predetermined series program and A message prompting the user to select a broadcast channel is displayed (step S701a).
Then, the CPU 142 determines whether or not the user has switched to the network and channel on which the series program is broadcast within a predetermined time based on the input operation signal from the remote control unit 2 (step S702a), and the switching is performed within the predetermined time. If it is not (step S702a; Yes), the process proceeds to B1, and if it is not switched within the predetermined time (step S702a; No), B2 is terminated.

Note that, as shown in FIG. 17 or FIG. 18, the B2 process is performed when the user selects a channel different from the broadcast channel of the predetermined series program determined in step S502. It may be a process of determining whether or not to tune to a broadcast channel.
That is, when the CPU 142 executes the determination program 144t, the message display program 144s is executed to confirm the copyright protection method on the display screen 200a of the television receiver 200 as shown in FIG. A message for determining whether or not to select a network of a predetermined series program and select a broadcast channel is displayed (step S701b).
Then, when switching to the broadcast channel on which the series program is broadcast is selected by the user (step S702b; Yes), the CPU 142 proceeds to B1, and returns to the broadcast channel before switching after the end of B1 (step S703b). End B2.
On the other hand, if the user has not selected switching to the broadcast channel on which the series program is broadcast within a predetermined time (step S702b; No), the CPU 142 ends B2.

<Remaining copy number update process>
Next, with reference to the flowchart of FIG. 25, description will be given of the copy processable remaining number update process of the series program recorded in the HDD drive 8 in the HDD recorder 1.

  First, by executing the recorded series program information determination program 144e of the CPU 142, the user operates the remote controller 2 to copy the digital broadcast data including the series program information whose “recording date” is described in the table 145. When selected, the CPU 142 executes the copy processing program 144z to perform copy processing on the recording medium of the DVD drive 18 (step S801).

  Next, the CPU 142 executes the copy processing number calculation program 144f, and updates the digital broadcast data to increase the number of times the disk drive 8 has been copied (history information) by one (the amount that has been copied in step S801). Is performed (step S802).

Then, the CPU 142 calculates the remaining copy processable number for the digital broadcast data by executing the copy remaining number calculation program 144g, and updates the “copy processable remaining number” in the table 145 (step S803).

  According to the HDD recorder 1 of the present embodiment described above, the series program information is searched from the program information via the extraction unit 3 and executed in the table 145 by the execution of the series program information search program 144a and the series program storage program 144b. Remember. Then, by executing the receiving program 144c, digital broadcast data having the same series program information as the series program information is received, and by executing the determining program 144d, the copyright protection method of the digital broadcast data is determined, The series program information of the digital broadcast data and the determination result can be displayed as a list by executing the list display control program 144i.

That is, it can be said that the HDD recorder 1 is a recording / reproducing apparatus that can specify a copyright protection method adopted for a series program and notify the user of the specified copyright protection method.
I can do it.

  Further, a network to which digital broadcast data including the series program information searched by the execution of the series program information search program 144a is transmitted is specified by the tuner unit 3, and the series program storage program 144b is executed to Since the network names are stored in the table 145 in association with each other, the list display control program 144i can be switched to display the list for each network.

  That is, the HDD recorder 1 arranges the information for each network even if the information related to each series program displayed in a list (including the copyright protection method set for the series program) becomes enormous and the display becomes complicated. In this state, it is possible to grasp information regarding each series program.

  Further, when it is determined by execution of the time determination program 144q that the current time measured by the timer unit 16 is a predetermined time before the scheduled broadcast date and time included in the series program information, it is specified by execution of the specification program 144p. Whether or not the network selected by the user and the selected broadcast channel matches the network name and broadcast channel of the series program information stored in the series table 146 is determined by executing the match determination program 144r. If it is determined that they do not match, the message display program is executed, and the predetermined display is displayed to prompt the user to select a network corresponding to the series program information and to select a broadcast channel. Can be made to do.

  In other words, the HDD recorder 1 allows the user to select the network and the broadcast channel in advance when the series program for determining the copyright protection method is a broadcast channel different from the channel that the user is viewing (channel selection). Since the station is urged, the user's viewing of the program is not hindered by a surprise.

  In addition, by executing the determination program 144t, a message is displayed to prompt the user to select a network corresponding to the series program information and to select a broadcast channel, and broadcast corresponding to the series program information via the remote control unit 2. Only when it is determined whether or not to select the type and select the broadcast channel, and when it is determined to execute, the reception program 144c is executed to receive digital broadcast data having the same series program information as the series program information. I can do it.

  That is, as described above, the HDD recorder 1 can prompt the user to select a network and select a broadcast channel in advance, and can determine whether or not to select / select based on the user's intention.
