Description

  The present invention relates to a broadcast receiving apparatus, and more particularly to a broadcast receiving apparatus equipped with a V-Chip for performing broadcast viewing restriction.

  In recent years, there have been broadcast receiving apparatuses having various broadcast receiving functions due to the multi-functionality and diversification of television broadcasts such as digital broadcasts and data broadcasts. As one of such broadcast receiving functions, there is a viewing restriction function that restricts viewing of a specific program.

  For example, in BS broadcasting and CS broadcasting, since a contract is made for each program, a program outside the contract cannot be viewed by the scramble function. In addition, in the V (Violence) -Chip system adopted in the United States and Canada, viewing can be restricted on a program-by-program basis according to the standards of the broadcasting station.

  In the V-Chip system, it is obliged to install a V-Chip for restricting reception of a predetermined program inside a broadcast receiving apparatus. V-Chip is a device made up of a microchip or the like that prevents extreme violence and sexual scenes from appearing on a television screen. When the V-Chip receives a program viewing request from the user, the V-Chip checks a preset condition and determines whether to display the designated program on the screen.

  In V-Chip, restriction level information (hereinafter referred to as “rating information”) including information such as the age at which viewing should be prohibited and the wording used in the program is used for each program. A V-Chip signal including rating information is usually transmitted by being superimposed on a VBI (Vertical Blanking Interval = vertical blanking interval) signal of a broadcast signal.

  In advance, the user performs condition setting (hereinafter referred to as “rating setting”) of a program whose viewing is to be restricted to V-Chip. As a result, even if a child selects a program including rating information restricted in the rating setting, the image and sound of the program are not displayed on the screen, and viewing is impossible.

  When rating is set for V-Chip, a plurality of categories such as genre and wording (hereinafter referred to as “viewing restriction items”) and a plurality of restriction levels for each viewing restriction item are displayed on the setting screen. The By operating a remote controller or the like on this screen, it is possible to select the validity / invalidity of restriction and the restriction level for each viewing restriction item.

  In relation to the above, Patent Document 1 discloses a V-Chip on-board television broadcast receiving apparatus capable of finely setting viewing restrictions for each program content based on the user's own standards. This television broadcast receiving apparatus receives a request for releasing viewing restriction for a program that is restricted in viewing level set based on the V-Chip restriction, and performs processing for releasing the restriction on viewing of the program. In addition, a request for viewing restriction for a program that is not restricted by the viewing level set based on the V-Chip restriction is received, and the viewing restriction process for the program is performed.

  When there is a request for viewing a program, whether or not the image / sound information received by the output control means is viewable is determined based on viewing availability information indicating whether viewing is possible based on the viewing restriction release processing and the viewing restriction processing. Thus, it is possible to finely cancel viewing restrictions and restrict viewing for each program content without depending on the standards on the broadcast station side or the playback device side.

Further, in relation to the above, Patent Document 2 discloses a television broadcast receiving apparatus that can easily perform an optimal rating setting of V-Chip. This television broadcast receiving apparatus records the viewing restriction information added to the selected program information in association with the information specifying the program. It also has a function to display a list of each recorded information. As a result, it is possible to record and display a list of information for specifying a program selected in the past and viewing restriction information attached to the program in association with each other. For this reason, the correspondence between the program content and the level is easily understood by the user, and the optimum level can be easily selected.

  Embodiments of the present invention will be described below with reference to the drawings. In addition, embodiment shown here is an example and this invention is not limited to embodiment shown here.

<1. Internal configuration>
FIG. 2 is a block diagram showing the television apparatus 1 (= broadcast receiving apparatus) according to the present invention. The television apparatus 1 includes at least a control unit 11, a memory 12, a flash memory 13 (= recording unit), a tuner 14, a signal processing unit 15, an audio circuit 16, a speaker 17, a color reproduction circuit 18, and an OSD processing unit 19 (= An image signal superimposing unit), a monitor 20, an operation button group 21, and 22 remote control receiving units. A remote controller 60 is provided as an external device.

  The control unit 11 is an arithmetic device configured by a plurality of LSIs for controlling each device of the television device 1. Thereby, the control unit 11 performs overall control of display processing of the television broadcast received by the tuner 14. Further, the control unit 11 is configured to include an LSI called V-Chip for restricting viewing of a broadcast program. Details of V-Chip will be described later.

  The memory 12 is a medium for temporarily recording various data held by the television device 1, and is configured by, for example, a writable RAM (Random Access Memory). The memory 12 has a role as a buffer memory for temporarily recording, for example, processing data when various kinds of information processing are performed by the control unit 11 and instruction commands received from the user.

  The flash memory 13 is a non-volatile semiconductor memory that can be rewritten and does not lose data even when the power is turned off. The flash memory 13 is a kind of EEPROM, but unlike the EEPROM, it cannot be rewritten in units of 1 byte, and is written after erasing in units of blocks in advance. In the present invention, it is used for recording a rating table (= viewing restriction table) for restricting viewing of received programs.

  The tuner 14 selects a television broadcast and receives a high frequency signal, and also obtains an intermediate frequency signal by performing amplification and frequency conversion of the high frequency signal. The obtained intermediate frequency signal is given to the next signal processing unit 15.

  The signal processing unit 15 obtains an audio signal and an image signal by performing amplification and detection of the intermediate frequency signal input from the tuner 14. Further, various accompanying data included in the intermediate frequency signal, for example, EPG (Electronic Program Guide) data, viewing restriction flag data described later, and the like are extracted. The audio signal is supplied to the audio circuit 16, the image signal is supplied to the color reproduction circuit 18, and the accompanying data is supplied to the control unit 11.

  The audio circuit 16 performs D / A conversion and amplification processing on the audio signal supplied from the signal processing unit 15, and outputs audio from the speaker 17. The color reproduction circuit 18 converts the image signal given from the signal processing unit 15 into a primary color signal. The primary color signal obtained by the conversion is given to the OSD processing unit 19.

  The OSD processing unit 19 superimposes an image signal for indicating character information or the like on the primary color signal. For example, when a setting instruction for a viewing restriction function is issued, the OSD processing unit 19 superimposes an image signal for displaying a table image or the like indicating various rating tables for performing the viewing restriction setting. The superimposed primary color signal is output to the monitor 20 and displayed. The monitor 20 is a display device that includes a liquid crystal element, a backlight, and the like.

  The operation button group 21 is for the user to give various instructions such as a channel selection instruction and a power supply start / stop instruction to the television apparatus 1. The instruction output from the operation button group 21 is received by the control unit 11 and performs various control processes based on the content of the instruction.

  The remote control receiving unit 22 receives an infrared signal transmitted from the remote control 60 and acquires a remote control code included in the infrared signal. Then, a control instruction corresponding to the remote control code is given to the control unit 11. The remote controller 60 is an external device for remotely operating the television device 1.

<2. About the configuration of the function section>
Here, the relationship among the functional units for performing the viewing restriction process in the television apparatus 1 according to the present invention will be described with reference to the functional block diagram of FIG.

  As shown in FIG. 1, at least the viewing restriction processing of the present invention includes at least a V-Chip 11a (= viewing restriction processing unit), a table setting unit 11b, a flash memory 13, a tuner 14, and a signal processing unit included in the control unit 11. 15, an OSD processing unit 19, a monitor 20, and an operation button group 21.

  The V-Chip 11a restricts viewing of television broadcasts received by the tuner 14 based on viewing restriction settings set in advance in the rating table. Specifically, the signal processing unit 15 checks the viewing restriction flag data included in the attached data extracted from the broadcast signal. The viewing restriction flag data is data to which individual flag data is added for each broadcast program, and indicates the age at which the broadcast program can be viewed and the attributes of the broadcast program (for example, including sexual expressions). .

  The V-Chip 11a compares the received viewing restriction flag data with the rating table previously set by the user and recorded in the flash memory 13, and determines whether to allow / disallow display of the received broadcast program. When not permitted, the V-Chip 11a prohibits the signal processing unit 15 from outputting image signals and audio signals of the corresponding broadcast program. Thereby, it is possible to prevent the received broadcast program from being output from the speaker 17 and the monitor 20. Details of the rating table and the viewing restriction flag will be described later.

  The table setting unit 11b receives an instruction to change the contents of the rating table. The content change instruction is issued, for example, when the user selects a rating table setting change using the operation button group 21 on a setting screen displayed by OSD. The table setting unit 11b that has received the content change instruction displays the rating table setting screen shown in FIGS. 4 to 7 using the OSD processing unit 19. When a user operation is received on this screen, the contents of the rating table are changed according to the received operation, and each rating table recorded in the flash memory 13 is updated.

<3. Rating table setting screen>
Here, a rating table setting screen for executing the viewing restriction function of the television apparatus 1 according to the present invention will be described with reference to the screen diagrams of FIGS.

  4 to 7 are examples of a rating table setting screen displayed on the monitor 20 when a setting instruction for the viewing restriction function is detected in the television apparatus 1 according to an embodiment of the present invention. The rating table includes a categorical table (= item-specific table) for individually setting viewing restrictions for a plurality of items, and an ordinary table (= level) for setting a plurality of items at once by specifying a viewing restriction level. There are two types:

  The rating table setting screen 50 shown in FIGS. 4 and 5 is a categorical table setting screen. The rating table setting screen 50 is configured to include at least a categorical table 51 and a cursor 52. The categorical table 51 is a table in which a plurality of setting items are displayed side by side, and is configured so that the item name of each setting item is included in the upper row and the setting value of each setting item is included in the lower row.

  In the example shown in FIG. 4, there are four setting items “violence”, “language”, “dialogue”, and “sexual” as setting items. The user can move the cursor 52 to the left and right by operating the operation button group 21 to select an item to be set. Then, whether or not viewing is possible is selected for the selected item. “V (Visible)” is set as the setting value for the item selected to be viewable, and “B (Block)” is set as the set value for the item selected to be unviewable.

  For example, in FIG. 4, when the cursor 52 is set to the item “dialogue” and the setting value of the item “dialogue” is changed from V to B, the categorical table 51 changes to the state shown in FIG. In this state, the broadcast program in which the “interactive” flag of the viewing restriction flag included in the broadcast signal is valid is restricted in output even if it is received so that the user cannot view it. The “dialogue” item is an item indicating that a broadcast program includes a lot of extreme conversations, for example, conversation expressions that are interpreted as contrary to general morality.

  An example of the data structure of the viewing restriction flag data will be described with reference to FIG. FIG. 8 shows an example of flag data (hereinafter referred to as “categorical flag”) corresponding to the categorical table 51 among a plurality of viewing restriction flag data included in the VBI (Vertical Blanking Interval) region of the broadcast signal. It is a thing. In the example shown in FIG. 8, the categorical flag has a 4-bit data structure. The first bit is a “violence” flag, the second bit is a “language” flag, the third bit is a “conversation” flag, and the fourth bit is a “sexual” flag.

  When the value of each bit is 1, it is valid, and when it is 0, it is invalid. In the example shown in FIG. 8, since “violence” and “language” are 1 (= valid), it is shown that this program broadcast includes a violent expression and a rough language. The control unit 11 that has received the broadcast signal collates this categorical flag with the categorical table 51 described above. If an item whose setting value is “B” in the categorical table 51 is valid in the categorical flag, the output of the program broadcast including the categorical flag is prohibited.

  For example, assume that the categorical table 51 is in the state shown in FIG. 5 and the categorical flag included in the broadcast signal is in the state shown in FIG. In this case, since the flag of the “dialogue” item whose setting value is “B” is 0 (= invalid), viewing restriction is not performed, and thus image and audio are output as usual.

  Next, the configuration of the ordinary table will be described. The rating table setting screen 60 shown in FIG. 6 and FIG. 7 is an ordinal table setting screen. The rating table setting screen 60 is configured to include at least an ordinary table 61 and a cursor 62. The ordinal table 61 is a table in which a plurality of setting items are displayed side by side, and is configured so that the item name of each setting item is included in the left column and the setting value of each setting item is included in the right column. The ordinary table 61 is used, for example, to perform age viewing restriction based on the viewer's age.

  In the example shown in FIG. 6, there are five setting items as “setting programs prohibited for viewing under 6 years old” to “prohibited viewing programs under 20 years old”. The user can select the setting target item by moving the cursor 62 up and down by operating the operation button group 21. Then, whether or not viewing is possible is selected for the selected item. “V” is set as the set value for the item selected to be viewable, and “B” is set as the set value for the item selected to be unviewable.

  Unlike the categorical table 51, the ordinal table 61 is set to “V” for all the upper items of the setting items when “V” is set. When “B” is set, all the lower items of the setting item are set to “B”.

  For example, in FIG. 6, when the cursor 52 is set to an item “prohibited viewing under 12 years old” and the setting value of the “prohibited viewing under 12 years” item is changed from V to B, the ordinary table 61 is The state changes to that shown in FIG. In this state, the broadcast program in which the “12 years old” to “20 years old” flag of the viewing restriction flag included in the broadcast signal is valid is restricted in output even if it is received so that the user cannot view it. .

  FIG. 9 shows flag data (hereinafter referred to as “ordinary flag”) corresponding to the ordinary table 61 among a plurality of viewing restriction flag data included in the VBI area of the broadcast signal. In the example shown in FIG. 9, the ordinal flag has a 5-bit data structure. The first bit is a “6 years old” flag, and the fifth bit is a “20 years old” flag.

  When the value of each bit is 1, it is valid, and when it is 0, it is invalid. In the example shown in FIG. 9, since “18 years old” is 1 (= valid), it is indicated that this program broadcast is a viewing prohibited program under 18 years old. The control unit 11 that has received the broadcast signal collates this ordinary flag with the aforementioned ordinary table 61. When an item whose set value is “B” in the ordinary table 61 is valid in the ordinal flag, the output of the program broadcast including the ordinal flag is prohibited.

  For example, assume that the ordinary table 61 is in the state shown in FIG. 7 and the ordinary flag included in the broadcast signal is in the state shown in FIG. In this case, since the flag of the “18-year-old and below viewing-prohibited program” item whose setting value is “B” is 1 (= valid), viewing restriction is performed and output of images and audio is prohibited.

<4. About rating table change processing>
Here, the rating table changing process of the television apparatus 1 according to the embodiment of the present invention is performed using the block diagrams of FIGS. 1 and 2, the flowchart of FIG. 3, and the screen diagrams of FIGS. While explaining.

  FIG. 3 is a flowchart showing a processing flow of the rating table change processing of the optical disc according to the present invention. This process is started when the user selects execution of the rating table by operating the operation button group 21 or the remote controller 60 on the menu screen or the like displayed by the OSD processing unit 19. Alternatively, it may be configured to start by detecting a remote control code transmitted when a setting change button (not shown) provided in the remote control 60 is pressed.

  After the start of this processing, in step S110, the table setting unit 11b acquires the type of rating table to be changed from the setting change instruction received from the user. In step S120, it is determined whether the acquired type is categorical or ordinary.

  If it is determined that it is categorical, the table setting unit 11b reads the categorical table 51 from the flash memory 13 in step S130. In step S140, the categorical table 51 is displayed so that the setting items are arranged side by side as shown in FIGS.

  Returning again to step S120, the table setting unit 11b reads the ordinary table 61 from the flash memory 13 in step S131 when it is determined in step S120 that it is an ordinary. In step S141, the ordinal table 61 is displayed so that the level setting items are arranged vertically as shown in FIGS.

  Next, in step S150, the table setting unit 11b waits for an instruction to change the categorical table 51 displayed in step S140 or the ordinary table 61 displayed in step S141. In this state, the user can select items and change settings using the cursor 52 or the cursor 62.

  Next, in step S160, the table setting unit 11b determines whether or not a change instruction by a user operation has been received within a predetermined time after shifting to the instruction waiting state. If the change instruction is not received within the predetermined time, the table display is stopped and the process is terminated. Conversely, when a change instruction is received within a predetermined time, the received change is reflected in each table recorded in the flash memory 13, and then the display of the table is stopped and the present process is terminated.
