The contents of the show are listed in order of extremeness Since it is not pushed, locking one content will automatically change the other. It does not lock the gap. Users can also lock a specific time zone to prevent watching TV during that time. You can also do it. Users can also add, for example, only a specific day, from Monday to Friday. Identify the frequency of locks, such as only, weekends only, or every day of the week. You can also. Figure 2E shows the user's input about when TV viewing should be prevented. Shows pop-up 62 to request. As shown, the user is Time to start the clock (default (default) time 2:30 pm) , Lock end time (default time is 5pm), and lock frequency (default time) Can identify one day). The user sets these values in advance In the situation where it was, the system remembers the value and a pop-up 62 is shown Display them at the time. The system mutes audio if TV viewing is attempted during locked hours And display a blue screen throughout the video. Request the parent password here A up-up will appear. When the correct password is entered, the shade The blue screen without a blank disappears and the audio is re-enabled. There is a program to be recorded A pop that alerts the user about inconsistencies if a lock is set in the time zone Up will appear. If the user ignores the popup, Up-up times out within 3 seconds, channel is locked, has lock Recording will be done without password request as it was set before it was activated. It becomes. However, for all future recordings scheduled during the locked time zone , Password is required. In Figure 2F, the purchase password is not set and the user is viewing control menu 66. Shown to users when they select the "Set IPPV Consumption Limits" feature A preferred embodiment of the pop-up 64 is shown. IPPV is Impulse Pay Abbreviation for par view, purchased via a user input device such as a remote control Means the PPV program to be entered. This means that the user can buy the show It's different from traditional PPV shows where you have to call the lobbyer over the phone. User -Press a key on the user input device or select it on the TV reservation guide Main menu by entering the SELECT key with either Purchase password from -50 Can be set. Figure 2G is viewed by the user with a purchase password set You when you select the "Set IPPV Consumption Limit" function from Control Menu 66 A preferred embodiment of the pop-up 68 shown in the Zar is shown. In this case, you The user simply enters the purchase password and then the SELECT key. To. If the user is wrong, as shown in Figure 2G, the user CAN You can enter the CEL key and re-enter the password. Once the purchase password is set and entered, the user will be IPPV Looking at the consumption limit pop-up 70 (as shown in Figure 2H), the system IPPV consumption should be restricted before requesting a password to activate the purchase You can enter the total amount. Default consumption is zero, in which case the user Must enter the purchase password for all purchases. Gold greater than zero If the forehead is set, this will be the purchase password to make additional purchases The amount that the user can spend before being requested. To set this amount , The user can enter the right arrow key, each time the right arrow key is entered, the limit $ 1 will be added to. To reduce the amount, the user uses the left arrow key can do. The user has an eye to reset the amount whenever desired You can use the arrow keys on the target. To access the locked program, the user can access the parent control menu 54 You can select the "Unlock All" function from, and all locked programs Will be unlocked. Alternatively, while the user is in the guide From the TV reservation information guide by pressing the SELECT key for about 1 second All locks can be unlocked. A pop-up will appear, Yu The user can select the "Unlock All" option. The system will ask the user for the parent password, which is the correct password At the time of input, the user will be on all programs on all available channels. Can be synchronized. While the show is unlocked, "All locks The "unlock" function has been switched to the "relock all locks" function, and the guy The gray lock symbol in the box is the red unlocked lock symbol. The user is the parent control Previously by selecting "Relock All Locks" from New 54 You can relock all the programs that have been locked. To switch off the TV Therefore, all parent locks will be automatically restored. Alternatively, the user can go directly to the show from either the TV or the TV booking guide. Unlock individual programs by synchronizing and entering the correct password Can be removed. If the user tunes to a locked channel The system displays a blue screen across the TV screen and mutes the audio .. A popup will appear asking for the parent password. Correct password When supplied, the system removes the blue screen and restores audio. Shi However, in this case, the user cut the previously locked channel in the middle. At that point, the parent lock will be restored automatically. So the user is locked If the channel is cut off in the middle and then retuned back, the user is locked. You have to re-enter your password to watch the channel. Users are locked to access individual programs that are locked from the guide Highlight on the guide what you want to watch on any of the programs It can be selected by entering the ELECT key. At this time, Paswa A pop-up will appear. The user enters the correct password If so, Sith Tem tunes to the channel with the desired program. The user is for more than 1 second You can also enter the SELECT key, at which time the number locked by the user A pop-up appears asking if you want to tune the pair or record it. .. When the user makes a selection, a password popup will appear and the user -Can enter the password. After the correct password is entered, the system will You will either tune in to a locked program or record it. SELEC Instead of typing the T key and selecting a recording option on the pop-up, the user , Highlight the locked show and enter the REC key to request the show to be recorded You can also do it. Recording will proceed when the user supplies the correct password Is done. Figure 3 shows a professional for deciding whether a user can tune in to a single show. An example of the Seth flowchart. In a preferred embodiment, described herein. The various processes that are running under the control of the software take The air is stored on a computer-readable storage medium. Preferred embodiment In the state, the system checks in step 100 whether a parent password is required. To do. In step 102, the system provides the user with the correct parent password. Decide if you did. If the correct parent password is entered, the process will Tep 104 will check if the show is a free event. Free Bent is a non-pay-per-view event. The event is free If so, the system will tune to the program in step 110. Event If is not free, the system will have the user purchase password in step 106 Request to enter. In step 108, the entered password is confirmed Will be done. If the password is correct, the system will follow the show in step 110. Make a key. Both confirmations If an incorrect password is provided for Tep 102 and 108, Stem does not tune to the requested program. Figure 4 is an example of a process flowchart for the operation of the parent control function. Show. The user turns on the TV or tunes to one program or channel At that point, the system at step 150, parent Paswa, before the show aired. Check if a card is needed. System if parent password exists Step 152 of step 152 checks whether or not the BOX lock is set. BOX b The cook is basically special because it keeps the TV locked 24 hours a day. TIME lock. If a BOX lock is present, step 154 is visual A password is required for listeners to be able to watch TV In step 172, the user is the parent Prompt to enter password. The user provided the correct password At this point, tune to the show in step 168, reserve automatic tune. Or you can schedule recording of the program. If the BOX lock is not set, the system will be chased in step 156. Inspect for tunnel lock. If it does not exist at all, step 158 , TIME Check for locks. Step if TIME lock exists 170 checks if the current time is within the constrained time range. user If you are trying to watch TV in a constrained time, you in step 172 Ther is asked to provide the parent password. Similarly, channel lock Is present and the user is trying to tune to the locked channel If so, the user will be asked to provide the password in step 172. It becomes. If the user is watching TV at an unconstrained time, the user Step 16 You can go to 8 and also tune in to the show or record the show it can. If no TIME lock is set, the rating will be American Film Association Step 160 is a rating / MPA as it corresponds to the one set by the association Inspect for A lock. If the rating lock was set, step 1 64 determines whether the program has a constrained rating. Constrained rating If so, the user will provide the parent password in step 172. Receive a request. On the other hand, if there is no rating lock, step 162 is content / Check for ATTRIBUTE locks. The system smells step 166 And check if the program contains constrained content, and if so, the user Is requested to provide the parent password in step 172. Step In addition, if the program does not contain constrained content, the program will be V-clicked. Inspect whether or not it has a classification. If you have this, step 178 (see Figure 7) (Details) allows users to access programs with constrained V-chip classifications Decide if you are trying to get. Figure 5, which describes step 106 in more detail, is an operation of the purchase control function. Illustrate the process flow chart for the operation. User is the same as one program At the time of adjustment, step 200 determines whether the purchase password has been set. inspect. If set, step 204 checks to see if the limit has been exceeded. .. Step 172 requests a purchase password if the limit is exceeded. Do not exceed If so, the system continues the purchasing process in step 208. Step 200 So, even if it is determined that the purchase password was not set, the system will Similarly, step 208 will continue the purchasing process. Figure 6, which describes step 172 in more detail, shows the purchase or entering the parent password. A professional to check passwords and limit the number of user attempts An example of the Seth flowchart. In step 250, the user is applicable Receive a request to provide a password. Step 252 is the user's input Upon receipt, step 254 checks to see if the password is in the proper format. If the password is incorrect, for example too many characters, step 256 Displays a message informing the user that the password is invalid To. Step 252 is repeated and the user re-enters the appropriate password Can be done. As shown, the user assumes that the password is incorrect If rejected, you can re-enter your password an infinite number of times. Once the user has entered the proper password, step 258 is Make sure the password you entered is correct. If correct, step 260 , Allows users access to locked programs. However, If the password entered is incorrect, step 262 is for the user to be correct. Keep track of the number of attempts to enter no password. Step 264 is 26 Compare the count at 2 with the number 3. If the count at 262 is less than 3, then Tep 256 shows a pop-up with an illegal password and the user steps You can re-enter your password at 252. User correct path more than 3 times If you try to enter a word, step 266 is the password entry attempt times. Shows a popup telling the user that there are too many, and the user passes You have to wait 15 minutes before trying to retype the word. Step Before 268 and 270 set the flag and allow the user to re-enter the password To start the 15 minute constraint. In a preferred embodiment, disconnecting the system from power is a 15 minute constraint. Will not be avoided. Conversely, when the system is reconnected to power, 1 By resetting the 5 minute time zone, the user can re-enter the password You will have to wait a long time. The system ensures password confidentiality Therefore, the user is restricted to three attempts to enter the correct password. Permitted Non-users preferably waited at least 15 minutes after every 3 attempts Probability of unauthorized users breaking into passwords as they will have to Not very expensive. Step 178 is described in more detail. Figure 7 shows the program-constrained V-chip. To determine if it has a class and if the user should be granted access The process flowchart of is illustrated. V-chip data is one channel The show has a constrained V-chip classification because it comes from a video stream of One way to decide if or not is to first access the data. It is to tune in to the channel. For example, a user is watching channel 9 Suppose you want to tune in to channel 3. See Figure 7, Chang If the system determines that the program on Nell 3 has a V-chip classification, The device 300 saves the video and audio volume information of channel 9. System In step 302, the user is changing the channel from the TV screen. Or decide that you are changing from within the guide. User T the channel If you are changing from the V screen, step 304 is blue across the TV screen Put a color screen. Alternatively, if the user is changing the channel from within the guide, P 306 applies a blue frame around the guide and is not covered by the guide Block the part of the screen. Step 3 In 08, the system mutes the audio so that users don't have to listen to the show To. Step 310 is the requested channel, which is channel 3 in this example. Synchronize with the channel, step 312 from the video stream of the channel Read the update. Step 314 is a classification with constrained V-chip classification Decide whether or not to do so. Otherwise, the user tunes to the show on channel 3 Can be done. However, the program has a constrained V-chip classification If so, the user is asked to provide the parent password in step 172. Step 316 verifies that the user has provided the correct parent password and provides it. If so, step 318 is the sound of the channel (channel 3 in this case) Restore voice volume. The user is on either the TV screen or the guide Step 324 goes to step 304, depending on whether you were changing channels Remove the blue screen placed more or step 322 is the guide and screen You will clear the blue frame applied by Tep 306. Access is steep If not confirmed in P316, the audio will remain muted and blue The color screen or blue frame and guides stay on the screen. However, Users can also try to access other channels / programs. These channels / programs will be aired if they are not constrained. In another embodiment, the system accesses V-chip data. You don't have to tune to the channel first. V-chip rating data Included in the data stream with data about program titles, description, etc. The system can receive V-chip rating data in advance because it can be received in a similar manner. Can be received and the data stored in the database. In this embodiment Because the system can simply retrieve data from the database, V Parent control without first tuning to the channel to access the updater Can be applied. With reference to the example in Figure 7, the system is still channeled by the user. V-Chip Day for Channel 3 Programs from Database While in Le 9 Does the program on channel 3 have a V-chip classification by searching for information? You can decide whether or not. After searching for this information, the show has V-chip information If so, the system determines if the V-chip classification is a constrained classification. be able to. If so, a parent password is required, otherwise Stem tunes to the channel 3 program. Therefore, this embodiment is a system The system does not have to tune to the channel in the first place, so the system speaks Need to mute and set up a blue screen or blue frame around the guide Lose it. Figure 8 shows the process flow chart for changing the parent control or purchase password. Is illustrated. Step 350 requires a password, step 352 is the user Accept password input. Step 354 is whether the password is in the proper form Check if not, otherwise step 356 is an injustice password pop-up The user is asked to enter the appropriate password an unlimited number of times in step 352. You can re-enter. If the password you enter is in the correct form, P358 confirms that the password is actually the correct password. Ste The UP 360 keeps the number of times an incorrect password is entered. Step 360 And 362 indicate that the user must enter the correct password 3 Given the number of trials. After 3 attempts, the password entered is still correct If not, step 364 displays an "over-trial" popup .. The user sets the flag in steps 366 and 368 and opens the 15 minute constraint By the time the system allows any further password entry attempts to get started You have to wait 15 minutes. As mentioned above, is the user preferably a power source? 15 minutes of waiting cannot be avoided by disconnecting the system .. If the user provided the correct password in step 352, then step You can change the old password and enter the new password on the 370. Su Tep 372 ensures that the new password is in the correct form, otherwise If not, step 374 will display an invalid password popup and the user will Unlimited number of times, you can re-enter the appropriate new password in step 370 To. If the new password entered is in the proper shape, the user will be entered To confirm that the new password is actually the desired password Tep 376 prompts you to re-enter your new password. Step 378 Now, the system will enter the password entered in step 370 in step 376. Compare with the entered password. If the two passwords are different, the user , To make sure the new password entered is the desired password You will be prompted to re-enter your new password in step 376, step 3 78 compares the password entered again. In steps 376 and 378, the password entered in step 376 is the same. It repeats until it matches the password entered in step 370. Or again, you The user can also leave the process, in which case the password has not changed. .. Alternatively, password 370 is password after step 378 makes that comparison. If different from Seward 376, steps 370-378 are repeated. this thing That is, the user ensures that the input in step 370 is correct. To re-enter the new password in step 370 and password in step 376 It means that you can reconfirm the word. Step 378 has two passwords Compare and if they are the same, step 380 will change the old password to the new password Change to Seward. Figure 9 shows a process flow chart for setting a parent control or purchase password. Is illustrated. Step 400 asks for a password and step 402 is the user Accepts the password input. In step 404, the system has a password Inspect for a sharp shape, otherwise step 406 is an injustice Display a Seward popup and the user will have unlimited in step 402 You can re-enter the appropriate password as many times as you like. The entered password is suitable If it is in the shape of a password, the user actually wants the password entered. Re-enter your password in step 408 to verify that it is a word Is required. Step 410 uses the password entered in step 402. Compare with the password entered in step 408. Two passwords are different If the user has entered a new password, it should be the desired password.
