- a consumer V-Chip television system would allow a consumer to program his or her television system to exclude programs according to their preferred levels of one or more of these rating criteria or alternatively could be programmed to permit only programs having certain levels of content according to these rating categories.
- V-Chip system A problem with the V-Chip system, as recognized in an article by T. Atherton, entitled “Living With the V-Chip,” The Ottawa Citizen, Entertainment, Section F, pp. FI- F2 (Saturday, March 9, 1996), is that the perceived utility of the V-Chip system to a consumer depends on whether the consumer agrees with the subjective ratings contained in the VBI for most, if not all, - programs.
- the author of this article who purportedly has been involved in a "Beta-test" of the V-Chip system in Canada, gives two illustrative examples in his article.
- ⁇ of program such as excluding all programs with a rating above PG, results in the blocking out of many programs which the author considers appropriate for viewing and does not wish blocked out, such as the movie Forrest Gump.
- the present invention is directed to an apparatus and method that satisfies this need.
- an apparatus for parental control of a television receiver A memory provides storage of information relating to television programming.
- a microprocessor generates a blocking command as a function of the information stored in memory including a master password.
- a blocking circuit which passes a baseband television video signal to a television display, provides blocking of the video signal in response to the blocking command. The blocking can be overridden by a user-provided list in the memory.

- a preferred embodiment of the present invention is a combination of the V-Chip system and a parental control system more oriented around programming by a user for blocking and enabling particular television programs.
- a parental control system is described in U.S. Patent No. 5,382,983, which is hereby incorporated by reference as if set forth in full herein.
- the 5 preferred embodiment adds functionality which allows the two systems to work together to form a system which is an improvement over either system.
- the user is allowed to override the operation of the V-Chip system for particular programs contained in user programmable enable override lists and blocking override lists.
- the parental control functions are accessed and selected in two different modes based on the preference of the user. In the TV 0 mode, a variety of interactive television screens display functions and user choices using text and graphics. In the GUIDE mode, the function and choices are made available to the user through menus in a program guide context.
- FIG. 1 a flow chart of the operation of this override system is shown.
- the V-Chip system operates as originally designed: a program is tuned, resulting in an output indicating that either the program should be blocked or should not be blocked, according to the user's programming of the V-Chip system. If, according to the V-Chip system, the program should be blocked, the Yes Path from block 1 is followed to block 2.
- the program being tuned is checked against a list of programs which have been specifically enabled by the user called the enable override list. If the program being tuned does not appear on the enable override list, the No Path out of block 2 is followed to block 3 in which the program being tuned is blocked. If, on the other hand, it is found in block 2 that the program being tuned is contained in the enable override list, then the Yes Path out of block 2 is followed to block 4 which enables the program to be tuned.
- the No Path out of block 1 is followed to block 5.
- the program to be tuned is compared against a override list to block particular programs (the "blocking override list") in a similar manner as is performed in block 2 for the enable override list. If the program to be tuned is found to be contained in the blocking override list, the Yes Path out of block 5 is followed to block 6 and the program being tuned is blocked. If the program being tuned is not contained in the blocking override list in block 5, then the No Path from block 5 is followed to block 4, in which case the program is allowed to be tuned.
- the blocking override list and enable override list may be defined in a number of ways.
- One way would be to define programs by channel, date, start time and length (or ending time).
- a clock and a link to the tuner would be employed to determine whether the program being tuned falls within any of the sets of channel, date, time and length information contained in either of the override lists.
- the lists could consist of compressed codes such as those described in U.S. Patent No. 5,335,079.
- compressed codes such as those described in U.S. Patent No. 5,335,079.
- PlusCodeTM numbers used by Gemstar Development Corporation's VCRPlus+® systems that presently appear in television calendars and may be used to enter the selected programs, rather than using the more laborious and time consuming approach of inputting the uncompressed channel, date, time and length of the program that is selected.
- the lists could be composed of the titles of television programs desired to be on the override lists. These titles could be compared against title information broadcast in the VBI with each program as part of the V-Chip coding information, using the XDS system or other similar system. Alternatively, the titles could be compared to a database which relates the channel, date, time, length to program titles, such as that contained in many electronic television guides.
- a problem that arises in implementing the system described in FIG. 1 is that the blocking override list and the enable override list can be, and in most cases will be, very cumbersome to create.
- One solution to this problem is using a system similar to that described in co-pending U.S. application 08/031 ,246, filed March 12, 1993 , which is hereby incorporated by reference as if fully set forth herein.
- a user would call a representative on the telephone and relate various selection criteria that are important to the user to the representative. These selection criteria may include television channels, times of day, program titles, program subject matter categories, and actors and actresses appearing in the programs.
- the representative would have
- this extensive database could include a variety of additional rating systems other than those provided by the broadcasters in conjunction with the V-Chip system. Any of a variety of third parties might provide such ratings such as religious organizations, newspapers and rating services targeted to particular . segments of the user public. Based upon the selection criteria provided by the user, the representative's computer downloads the data to program the user's system, by telephone, VBI, or other available data path.
- _ n ratings may be stored locally in the user's system.
- This embodiment would become feasible is if the system is combined with a locally stored electronic program guide which already stores the channel, date, time, length, title, category and descriptions of a large number of future scheduled television programs.
- FIG.2 A preferred embodiment of an override system for use with the V-Chip system described above is shown in FIG.2.
- RF radio frequency
- _ ⁇ is connected to the input of a cable box 10, which has a channel changing control.
- the output of the television drive circuity 12 is connected by a transmission blocking circuit 14 to a television display 16.
- Blocking circuit 14 could be a conventional analog signal transmission gate, or any other similar device known in the
- the television signal of each channel carried by the cable feed contains supplemental data, including channel identification, such as HBO, CNN, or NBC.
- channel identification is embedded in the VBI of the signal of each channel in an XDS format.
- the output of the television drive circuitry 12 is also connected to the input of a VBI decoder 18, which strips the XDS signal from the baseband television signal.
- VBI decoder 18 which includes a data signal representative of the channel identification of the channel to which the cable box 10 is tuned, is coupled to a microprocessor 20, the output of which controls the blocking circuit 14.
- the microprocessor 20 is coupled to a RAM 22.
- the programs to be selectively blocked are stored in RAM 22.
- the date, time, channel and program length are stored in RAM 22 in a stack arrangement as described in U.S. Patent No. 5,382,983 ("the '983 patent") and co-pending U.S. application 08/684,678, the disclosures of which are hereby incorporated by reference as if set forth in full herein.
- the program blocking data base stored in RAM can be generated in a number of different ways. One way is to transmit groups of program data consisting of date, time, channel, and length content according to a customized rating service, as composed for example by a religious group, newspaper, or political association, and to download such data to RAM 22 from the VBI of the television signal or a telephone line.
- the viewer can call up an on-screen menu of choices of customized rating services that are transmitted in the VBI or telephone line, key in the selected service, and command the microprocessor 20 to download the group of program data corresponding to the selected service.
- Another way is to key in the data of the individual programs through a remote controller.
- a third way is to select the programs with a cursor from an on screen electronic program guide (“EPG"), in which the EPG data base is used both to determine the programs to be blocked and the programs to be viewed or recorded.
- EPG electronic program guide
- the microprocessor 20 continuously monitors the output of a real time clock in the microprocessor 20, and the channel identification of the channel to which cable box 10 is tuned, which is recovered by VBI decoder 18 or by monitoring the tuner and using a channel map. These monitored attributes are compared with the data of the program blocking database. Preferably, this is accomplished by arranging the data base in a stack in RAM 22 as described in the '983 patent such that the top of the stack is the next program telecast to be blocked. When a match is found, the microprocessor 20 actuates the blocking circuit 14, thereby preventing the TV display 16 from showing the program.
- a code is also included in the VBI which indicates one or more rating factors for the program then being aired.
- the user programs the television system to exclude programs according to one or more of these rating criteria.
- the user selections are stored in RAM 22, and compared with the code transmitted in the VBI.
- an excluded program is detected by the microprocessor 20, via the VBI decoder 18, an enable override list stored in RAM 22 is consulted.
- the blocking circuit 14, under microprocessor control prevents the excluded program from being presented to the TV display 16 if the program is not contained in the enable override list.
- a blocking override list stored in RAM 22 is checked by the microprocessor 20.
- the blocking circuit 14, under microprocessor control allows the program to pass to the TV display 16 if the program is not contained in the blocking override list.
- the television programs comprising the blocking override list and the enable override list are defined by channel, date, start time and length (or ending time), or through the use of compressed codes such as those described in U.S. Patent No. 5,335,079, an alternative arrangement is necessary to accommodate the addition of a cable box or video cassette recorder ("VCR").
- VCR video cassette recorder
- a cable box or VCR is connected to the front end of the television receiver.
- the cable box, or VCR has a tunable bandpass filter for tuning the desired channel.
- the television signal from the tuned channel is modulated onto a fixed carrier frequency, by way of example channel 3, and coupled to the television receiver.
- the television receiver is tuned to the carrier frequency output of the cable box, or VCR, regardless of the particular channel selected. Since the television receiver is always tuned to the fixed frequency, the microprocessor of FIG. 2 will be unable to ascertain when a blocked or selected television program is selected at the cable box, or VCR.
- FIG. 3 a preferred embodiment of the present invention is shown which accommodates a system employing both a cable box and a VCR implemented with a low cost mechanization using a simple switch S 1.
- the VCR tuning issue is resolved by connecting the video input of the VCR 23 to the video output of the TV tuner 24, which is always tuned to a parentally enabled program. There is no reason for the VCR 23 to have broadband input.
- the cable box 26 is used only for tuning scrambled programs.
- the user identifies the scrambled (premium) channels in his or her cable lineup. This can be automated or performed manually.
- the scrambled program providers will transmit their names (HBO ESPN, etc.) in the VBI of the television signal. Accordingly, when a scrambled channel is selected by the user, the cable box 26 is tuned to the
- VBI decoder 28 If the name cannot be identified, the channel is blocked.
- VCR recording may also be controlled by providing the VCR video input with the same signal that is provided to the display 30 by the TV tuner 24. This signal has already been processed to insure that it contains a program that has been authorized. Hence, the user can only record authorized programs.
- the microprocessor 32 checks to see (from setup table) if the requested channel is designated as a scrambled channel, and also checks to see (from PlusCode table) if this channel is unblocked for the particular time slot. If the television channel is unblocked and non-scrambled, switch S 1 is set to position 2 and the TV tuner 24 is tuned to the requested channel. If the requested channel is to be blocked, SI is set to position 4, so the TV tuner 24 has no input. The user may also record the displayed program (but no other program since the VCR video input comes from the TV tuner output).
- the microprocessor 32 checks to see if the requested channel is designated as a scrambled channel, and also checks to see (from PlusCode table) if this channel is unblocked for the particular time slot. If the television channel is unblocked and scrambled, SI is set to position 3, and the cable box 26 is tuned to the requested channel.
- the VBI decoder 28 monitors the cable box output, looking for the channel name in the VBI (broadcast say every minute). If a name is found, it is compared to the channel name in the channel setup table. If a match is detected, the TV tuner 24 is tuned to channel 3, and the program is displayed. If no match is detected, SI is switched to position 4, and the display 30 is blanked. Thus, if the user tries to manually change the cable box channel, the VBI name check will fail and SI will be switched to position 4 to blank the display. The user may also record the displayed program (but no other program since the VCR video input comes from the TV tuner output).
- FIG. 4 a detailed electrical diagram of a preferred embodiment of the present invention is shown incorporating the V-Chip system with the override system ("V-Chip Plus+ system").
- the V-Chip Plus+ system is responsive to compressed codes for creating the override lists, such as those described in U.S. Patent No. 5,335,079, and includes automatic channel mapping capability.
- a TV tuner 34 is positioned at the front end of the television receiver for passing a selected channel of a multichannel RF television signal.
- the -10- tuner 34 which can be any conventional tuner in the art, should provide amplification, downconversion to an intermediate frequency ("IF") and demodulation, as well as frequency tuning.
- the TV tuner 34 is coupled to television drive circuitry 36 which provides the signal processing required to amplify and downconvert the IF signal to a baseband television video signal.
- the output of the television drive circuitry 36 is connected to a blocking circuit 38.
- the blocking circuit 38 could be a conventional analog signal transmission gate, or any other similar device known in the art.
- the output of the blocking circuit 38 is connected to a TV display 42 through a video mixer 40 for selectively displaying the television program currently being broadcast on the selected channel.
- the TV tuner 34 is tuned to the selected channel by a microprocessor 44.
- a viewer input device 46 preferably in the form of a remote infrared (“IR") controller, is coupled to the microprocessor 44 to provide viewer control of the television channels.
- the viewer input device 46 also allows the viewer to remotely program the V-Chip Plus+ system to exclude programs according to one or more rating factors, as well as compiling or modifying the V-Chip Plus+ override lists.
- the microprocessor 44 retrieves the appropriate information from RAM 48 and couples it to the video processor 50, where the information is formatted for display.
- the information stored in the video processor 50 is a bit map of what is displayed on the TV display 42.
- the video processor 50 is connected to the video mixer 40.
- the video mixer 40 outputs the information as an overlay on the television program currently being viewed, although it will be understood by those skilled in the art that the information from the video mixer 40 could be presented to the TV display 42 as a window in the television program or as a full screen display instead of the television program.
- the viewer programs the V-Chip Plus+ system to exclude programs according to one or more rating factors.
- the viewer input device 46 allows manipulation of the V-Chip Plus+ rating system and the V-Chip Plus+ override lists by moving a cursor on the TV display 42 and inputting discrete commands. Cursor control is achieved by coupling the microprocessor 44 to the video processor 50 through to a cursor position register 52.
- Viewer edits to the V-Chip Plus+ override lists presented to the TV display 42 are preferably accomplished using compressed codes such as those described in U.S. Patent No. 5,335,079.

- the user may input a Plus Code and then select the action they wish to take on the program: record (the default), watch, or block. These options will appear as tiles in the Plus Code entry area.
- a blocked show may be set to be blocked once, daily or weekly. This is accomplished by placing any individual show (this does not apply to all shows set to be blocked by channel, time or rating) that is set to be blocked into the Schedule queue. These blocked shows will be mixed in with the shows set to record or watch in chronological order.
- the user may modify the frequency of the block in the same way they may do so for shows set to record or watch, by pressing an action button labeled "Change.” This will cycle through the frequency choices. Modifying the frequency can only be done while, the guide is in Master Mode.
- Scheduled events (shows scheduled to record, watch or blocked) can be stored in a nonvolatile memory such as an EEPROM. Thus, if a power outage occurs, the Scheduled events will be saved.
- VChip Plus+ in GUIDE mode uses two data sources in combination to determine whether a show should be blocked: data downloaded and stored in the guide (channel lineups, show schedules, show ratings), and rating data transmitted over the VBI.
- Ordinary V-Chip devices use the data transmitted over the VBI to determine whether or not to block a show by rating. These ratings are sent a minimum of every 15 seconds. Thus, a show a parent may wish blocked, may be seen for up to 15 seconds before the blocking takes effect.
- VChip Plus+ in GUIDE mode will use show rating data already stored in the Guide to determine whether a show should be blocked as soon as it begins, and use the VBI data to confirm if the show was properly blocked. If it was blocked in error, then the block will be removed. In the event the Guide does not have rating data stored on a given show, the show will be accessible, until the VBI data is obtained and a blocking decision made.
- Ads linked to shows that have been blocked by the blocking of the individual show, show channel, show theme, show rating, or show time slot will be denied access to (as with 0 any blocked show) until the Master Password is input.
- the blocking message will appear in the PIP.
- turning a channel off in the Editor does not result in blocking all access to that channel. Specifically, if an ad with a show linked to a channel turned off in the Editor is displayed, the user can still schedule that show for recording or watching, or tune to its related
- the PIP will tune to the channel related to the ad when the ad is highlighted, even though that channel has been turned off.

If the user declines to provide this information, the EPG will attempt to "learn" the information as described in a co- pending Patent Application Serial No.
- the display will depend upon whether Auto-Guide-On is activated, the entry show has been blocked, or the TV remote or front panel was used to turn on
- the Guide will always appear when the TV is turned on using the remote. If a Master Password has been set, the user will have access to shows, features and screens provided by the User Profile. If the entry show has not been blocked, the show video will appear in the PIG. All shows, channels, times, etc. that are blocked will be so marked withindian the Guide. The user will have access to all unrestricted shows and features and screens of the
- a password dialog box will appear in the info, box (see FIG. 66). If the user correctly inputs the Master Password, they obtain access to all shows, areas of the guide and features. If the user does not input the Master Password, they will maintain access as defined by the User Profile. If the entry show has been blocked, the PIG will be black and contain the following message: "Show Blocked by VChip Plus+J
- the Guide will not appear when the TV is turned on using the remote. If a Master Password has been set, the user will have access to shows, features and screens provided by the User Profile. If the entry show has not been blocked, the show video will appear on screen. If the entry show has been blocked, the TV video will be covered with a password dialog box (see FIG. 66). Again, if the users correctly inputs the Master Password, they obtain access to all shows, areas of the guide and features. If the users do not input the Master Password, they will maintain access as defined by the User Profile.
- a user intending on circumventing the VChip Plus+ blocking, may attempt to remove power from the TV with the hope that the blocking settings will be lost. Due to limitations in available EE ROM, not all settings can be stored in EE ROM. Following is a desired set of setting to be stored, in order of priority if EE ROM space permitting:
- a power failure notice will present itself on screen every time the TV is powered on by the remote or by the front panel until the Master Password is input. This will inform the users of the power outage.

From this screen the user may block all instances of shows with any given TV Parental Guideline Ratings, block an entire content rating or a combination of TV Parental Guidelines and content ratings. Blocking unrated programs is executed from this screen as well. The screen is divided into 3 areas: 1. Programs for children, 2. Programs for the entire audience, and 3. Unrated programs. The green action key is used to block and the blue action key is used to unblock the ratings. When a rating is blocked, that rating and all higher ratings in the same group are blocked. When a rating is unblocked, only that rating is unblocked.
- FIG. 46 shows the movie Ratings screen responsive to the selection of the Movie Ratings feature in Fig. 46. From this screen the user may block all instances of shows with any given MPAA Ratings. When a rating is blocked, that rating and all higher ratings are blocked. When a rating is unblocked, only that rating is unblocked. In this example, all the movies with rating G are unblocked.
- the screen of FIG. 50 is displayed.
- the VChip Plus+ Grid is in gray tones except for the PIG, ads, logos and the action bar. This is intended for differentiating it from the Guide's Grid Screen.

- a features screen is displayed. From this Features screen, the user may block access to the record and/or watch functions. Additionally, the user may select a Power Outage setting from this screen. After the VChip Plus+ Password feature is selected a Password screen is displayed. From this Password screen the user may set up the Master Password for the first time (if not done during initial setup) or may modify the current Master Password.
- a 4 digit numeric Master Password scheme is used to enable the establishment of a User Profile and provide unlimited (unprotected) access to the Guide screens and shows once a Master Password is established. Only one Master Password can be established. It is established either during initial setup (see FIG. 67) or later by entering the Password screen from the Guide menu (see FIG. 43) or the TV mode. Once a Master Password is established, the Master Password must be entered to execute blocking or unblocking. The Master Password must also be entered to access the Setup, Editor, and VChip Plus+ screens. Once entered, the TV is in Master Password (unprotected) mode until the TV is turned off, the user exits VChip Plus+ mode, or a certain time delay, which starts from the time when the user correctly enters the password, has expired.
- An user interface allows the users (parents) to pick their own passwords, and to disable the lockout when the passwords are lost.
- the functions of this Ul include, but not limited to, the following:
- FIG. 39 is a flow chart of the master password operation. Obviously not all operations would require a password. As shown in block 391, the following operations have password protection: changing the password, changing the V-Chip ratings, deleting a "blocked” program or deleting a "blocked” channel, changing the "Babysitter” function, unblocking a program or a channel within the "Babysitter” function, changing the clock (this is because a different clock will cause VChip Plus+ to block a different program), and changing the channel map (this is because a different channel map will cause VChip Plus+ to block a different channel).
- a Master password user can establish specific viewing (blocking) parameters for the User Profile, establish specific feature use limits (disable Recording or Watch) for the User Profile, modify the Master password, or enter all Guide screens and view, record or schedule to watch all shows. But, it is not necessary to input the Master Password to access unrestricted shows, channels, time slots, features and Guide screens.

- repeating the entry of a consistently incorrect password for a certain number of times can establish a new password.
- the new password is established by repeatedly entering the same incorrect password a certain number of times, and at the end of the process confirming -the newly established password (block 395).
- the date and time of the last time that the password was used is recorded and, as shown in block 397, that date and time for the previous login is then displayed.
- Access-blocking may be established on: individual shows; channels; themes (entire themes such as Movies, Sports, Children's or sub-themes such as Adventure, Drama, Baseball, Basketball, etc.); TV Parental Guideline or MPAA rating (including un-rated shows); time slot or day; and/or access to the Recording and Watch features.
- blocked shows will be available. Also, blocked shows may still be scheduled to record or watch once the Master Password is input. Any show scheduled to record or watch will be recorded or watched even if it is blocked previously or subsequently blocked.
- the record and watch features may be blocked also. If a user attempts to schedule a show to record or watch when the feature is blocked and the guide is not in Master Mode, the action will be denied and the Master Password dialog box will appear. If the Master Password is not input, the function of the Guide will be modified as follows:
- the user may not schedule any show to record via the Guide or VCR Plus+
- the user may not schedule any show to watch via the Guide or VCR Plus+
- any show scheduled to record or watch by the Master will still be executed even if these features are blocked. If these features are not blocked, a user without the Master Password may enter the Record/Watch Schedule and make changes to any shows in the queue.
- a VChip Plus+ Dialog box appears whenever access has been denied to a show, channel, time screen, feature, etc. via a VChip Plus+ block.
- This dialog box provides for input of the Master Password for access as shown in FIG. 66. Additional dialog boxes appear if the input is not the correct password.
