Title: VCR programming system

Description:
BACKGROUND OF THE INVENTION  
       [0001] The present invention relates generally to a system for programming a VCR and, more particularly, to a system and process for allowing a television user to easily program a VCR to record future programs.  
       [0002] The difficulty of setting a VCR for automatic recording at a future date is notorious. Even users who are technically sophisticated will often make mistakes in the VCR programming procedure that cause them to record the wrong program or not to record anything at all. This difficulty has even resulted in a substantial body of humor dedicated to the subject of programming VCRs.  
       [0003] The difficulty of VCR programming has been alleviated somewhat by the development of VCRs that use a television set as a display for user prompts and feedback to the user during the programming process. U.S. Pat. No. 4,908,713, issued Mar. 30, 1990 to Michael R. Levine, discloses such a VCR using the television set as a display for VCR programming with an interactive user interface for directing the user on a step-by-step basis. Such a user interface removes a great deal of the mystery from VCR programming, but users still have difficulty with such a command-based interface and encounter problems carrying out the programming without making mistakes that cause them to miss recording programs they would like to watch at a different time than when they are broadcast.  
       [0004] Commonly assigned U.S. Pat. No. 4,706,121, issued Nov. 10, 1987 to Patrick Young, discloses a system and process in which user selections from television schedule information are used for automatic control of a VCR. That patent also contains a description of a proposed user interface for such a system and process. However, the provision of a highly intuitive user interface that makes such a system and process easy and convenient to operate is a difficult task. Further development of this system and process has produced considerable change in the user interface as originally proposed.  
       [0005] From the foregoing, it is apparent that a simplified system for programming a VCR is desired.  
       SUMMARY OF THE INVENTION  
       [0006] The present invention provides a simple and convenient method and apparatus for programming a VCR. The system, utilizing a programming controller, presents a display on the viewer&#39;s television which contains a pattern representing a plurality of time intervals. The user programs the controller by indicating what time intervals on what week and on what channel are to be recorded. The controller then continually compares the current time with the programmed time until a match is found. When a match is found the controller activates the VCR, tunes the VCR to the desired channel, and initiates recording. When the controller determines that the VCR has recorded for the desired length of time, it stops the VCR from continuing to record and turns off the VCR&#39;s power.  
       [0007] In one embodiment of the invention, the programming display screen presents sufficient time indicators for a full seven day week. Each day is broken into 48 half hour intervals. The user is also able to select the week for which the programming instructions apply as well as whether the instructions apply once, on a daily basis, or on a weekly basis. After the user selects the recording time, day, and week, the controller requires that the user input the desired channel.  
       [0008] In another embodiment of the invention, the programming display screen presents a series of ½ hour time segments, beginning with the current time, for every channel of the user&#39;s television system. The user scrolls along the vertical axis to change the channel selection and scrolls along the horizontal axis to change the selected time interval.  
       [0009] A further understanding of the nature and advantages of the present invention may be realized by reference to the remaining portions of the specification and the drawings.  
       [0010] NOTE: Many of the names in the figures and/or specification may be the trademarks/servicemarks of others. Such names include “HBO” and “NBC.”

     DESCRIPTION OF THE PREFERRED EMBODIMENT  
     [0021]FIG. 1 is a block diagram of one embodiment of the invention. In this embodiment a programming controller  100  is coupled to a television  105 . When programming controller  100  is activated by a user using an input device  110 , a data processor  115  coupled to a data generator  120  generates a VCR programming instructional display. The information for the blank instructional display is stored in memory  125 , preferably a ROM device. The display is presented on a television screen  130 . The user selects the time of day, the day of the week, and the channel on which programming is to be recorded. The user also indicates the desired duration of recording. All of the VCR programming information is stored in a memory  135 . A clock  140 , integral to controller  100 , tracks the time of day as well as the day of the week. When processor  115  determines that the actual time of the day as well as the day of the week match the stored VCR programming instructions, processor  115  turns the power on VCR  145 , adjusts the VCR tuner to the desired channel, and initiates recording. When processor  115  determines that the selected recording duration has been completed, recording on VCR  145  is stopped and the power to VCR  145  is turned off.  
     [0022] In the preferred embodiment of the invention, controller  100  controls VCR  145  with an IR emitter  150 . IR emitter  150  is capable of emulating the infrared command instructions required by VCR  145 . Typically IR emitter  150  is placed at the end of a cable  155 . Cable  155  allows IR emitter  150  to be placed proximate to the IR receiver of VCR  145 . If desired, a look-up table of emulation commands can be stored in memory  125  thus allowing IR emitter  150  to emulate the IR command instructions for a variety of VCRs. Preferably the user inputs the selected VCR into controller  100  using input device  110 . Once a VCR has been selected, controller  100  determines the appropriate set of VCR commands utilizing the look-up table.  
     [0023] When the viewer wishes to play a prerecorded tape, the signal from VCR  145  to television  105  is sent via cable  160  as in a standard system. Furthermore, controller  100  does not inhibit the standard features of VCR  145 . Therefore the viewer can still program VCR  145  using the standard programming techniques for which VCR  145  was originally designed, i.e., using a series of programming steps or a menu system displayed on television monitor  130 .  
     [0024] Preferably, clock  140  is coupled to a read-out display  165 . Display  165  shows the current time and day, thus allowing the user to easily check the accuracy of controller  100 . In an alternate embodiment, the current time and day as recognized by clock  140  is presented on the VCR instructional display on television monitor  130 , this display being shown whenever the programming controller is activated. Although this embodiment requires that the user activate controller  100  to determine the accuracy of clock  140 , it has the advantage of size since controller  100  can now be further miniaturized. Furthermore, this embodiment allows the user to place controller  100  in a wider variety of locations since display  165  does not need to be easily viewable by the user.  
     [0025]FIG. 2 is a block diagram illustrating an alternate embodiment of the invention. In this embodiment programming controller  100  is within a VCR  205 . VCR  205  is connected to a television  210  and at least one source  215 . In this embodiment the clock which is integral to controller  100  is preferably the same clock as that utilized in the VCR.  
     [0026]FIG. 3 is a block diagram illustrating another embodiment of the invention. In this embodiment programming controller  100  is integrated into a stand-alone device, such as a decoder  305 . Decoder  305  may be of the sort used with a cable source  310  or a satellite direct broadcast source  315 . As in the system illustrated in FIG. 1, this embodiment of the invention requires an IR emitter  320  to control a VCR  325 . Typically a television  330  is connected directly to VCR  325  although in some systems it may be connected directly to decoder  305 .  
     [0027] In an alternate embodiment, very similar to that illustrated in FIG. 3, controller  100  is integrated into a personal computer (PC). In this embodiment the PC may be used in conjunction with the television system to supply the user with capabilities such as Internet access. The functionality of controller  100  can be easily integrated into the PC.  
     [0028]FIG. 4 is a flow chart illustrating the operation of the preferred embodiment of the invention. To program the user&#39;s VCR, the user turns on the television system (step  405 ), sets the television to the appropriate channel (step  410 ), and activates the programming controller (step  415 ). The television must be set to a predetermined channel since the programming controller only sends out programming information over a narrow frequency band. In the preferred embodiment the user is given a choice of channels, typically channels  3  and  4 . The programming controller includes a switch which allows the user to select the corresponding channel, preferably the channel with the least use in the viewer&#39;s geographic region.  
     [0029] After the controller has been activated, in the preferred embodiment of the invention the user is prompted to input an instruction set number (step  420 ). Although this step is not required, in the preferred embodiment of the invention the user is allowed to input several sets of VCR programming instructions into the controller. Therefore in this embodiment the user is able to use the controller to record numerous programs. Preferably the controller tracks the number of instructional sets entered and unexecuted to date and prompts the user to select the next number in the series. This system also allows the user to go back to a previously entered set of programming instructions and modify those instructions.  
     [0030] In the next step of programming the controller a display is presented on the viewer&#39;s television (step  425 ). The display contains a pattern representing the times of day, preferably in 30 minute increments and for each day of a seven day week. After deciding the desired recording time, typically using a printed program guide (step  430 ), the user selects the corresponding times from the display pattern (step  435 ). In the preferred embodiment of the invention, after the user selects the recording time and date, a prompt appears asking the user to input the desired channel (step  440 ). The user inputs the channel, preferably by pressing the number on a remote control (step  445 ). The set of VCR instructions comprised of the record start time, record stop time, day of the week, and channel are stored within the controller (step  450 ).  
     [0031] After the user has input the set of VCR programming instructions, the controller displays the selected information and asks the user to verify that the proper choices have been stored (step  455 ). Assuming that the user neither modifies the current set of instructions or seeks to input additional instructions, the user deactivates the controller and resumes the normal use of the television (step  460 ).  
     [0032] The controller continuously monitors the current time and day, comparing the data with the stored VCR programming instructions (step  465 ). When the current time is greater than or equal to the stored start time (step  467 ), the controller turns on the VCR (step  470 ), tunes the VCR to the selected channel (step  475 ), and initiates recording (step  480 ). When the controller determines that the current time is greater than or equal to the desired stop time (steps  485  and  487 ), the controller stops the recording ( 490 ), turns off the VCR (step  495 ), and erases the set of programming instructions from the controller memory (step  499 ).  
     [0033]FIG. 5 is an illustration of the preferred embodiment of a VCR programming screen  500 . Screen  500  is divided into a seven day grid. The day of the week is indicated in a portion  505 . Adjacent to each day of the week  505  is a linear grid  510 . Grid  510  divides each 24 hour day into 48 half hour increments.  
     [0034] In the preferred embodiment, the user selects the times over which recording is desired, for example by moving a cursor to the desired time slot and pressing ENTER. In order to aid the user in navigating through the programming screen, preferably each grid segment becomes temporarily highlighted as the cursor passes over it. Thus if the user wishes to record a program on Thursday night starting at 9:00 PM and ending at 9:30 PM, the user simply moves the cursor to the 9:00 PM slot for Thursday night and presses enter. In the preferred embodiment, if the user wishes to record a program which lasts longer than 30 minutes, the user moves the cursor to each successive time slot and presses enter.  
     [0035] After the user indicates a specific day and time period, in this embodiment the program guide requests that the user enter a channel number. In one embodiment screen  500  begins flashing a question mark (i.e., “?”) in a portion  520  adjacent to the day of the week on which recording has been requested. The system can also be designed to send the user a request to input the desired channel, for example by scrolling a request message across screen  500  in area  525 .  
     [0036] Once the user has indicated the time, day, and channel for recording, the system may notify the user that either the programming has been successfully completed or that the programming was not successfully completed. An example of why the programming may have been unsuccessful is that the user programmed the system to record two different channels at the same time.  
     [0037] In one embodiment of the invention, the system allows the user to input several sets of VCR programming instructions. Preferably in this embodiment when the user initiates the system a screen  600  appears, as illustrated in FIG. 6. Screen  600  prompts the user to select a specific PROGRAM, in this case a program refers to a set of VCR programming instructions. Typically the user would select a program using either a cursor, or by simply typing in the desired number on the remote keypad. If the user wants to modify a previously input program, they simply select the representative program number. The system can be designed to prompt the user as to the next available program, for example by flashing the number of the next available program.  
     [0038] Due to the limited resolution of a standard television screen as seen from a standard viewing distance, a screen which conveys less information than screen  500  may be preferable. FIG. 7 is an illustration of a screen  700 . Instead of showing information for a full 7 day schedule, screen  700  only provides a single day of programming. The day of the week for which the programming information is provided is shown in a cell  705 . Preferably the day shown in portion  705  is the current day. If the user wishes to input programming instructions for a later day, the user scrolls through the days using DAY UP and DAY DOWN buttons on the remote control device. In order to conserve space, simple arrow buttons can be used, thus allowing the same buttons to be used for a variety of functions.  
     [0039] Screen  700  breaks the 24 hour day into 48 individual thirty minute intervals. Although the 48 intervals can be presented in a variety of ways, preferably they are spread throughout four rows  710 . To help the user navigate through the grid, above each row is a time of day descriptor  715  such as AFTERNOON. Another aid to user navigation is to color code the time segments. For example, all segments  720  representing hours (e.g., 12, 1, 2, etc.) may be of one color while all segments  725  representing ½ hours (e.g., 12:30, 1:30, 2:30, etc.) may be of a second color.  
     [0040] In an embodiment of the invention utilizing screen  700 , once the user has selected the day and time, a separate screen  800  is displayed. Screen  800  is a channel selection screen. Screen  800  has a table of channel numbers  805  from which the user selects the desired channel. Preferably screen  800  is limited to the channels available on the user&#39;s television system, thereby avoiding confusion and minimizing errors. For example, in screen  800  a “-” is shown at portion  810  between channels  3  and  5 , thus indicating that channel  4  is not available through the user&#39;s television system. Another aid to identifying channels is the use of broadcaster designators, for example HBO and NBC shown at  815 .  
     [0041]FIG. 9 is an illustration of an alternate programming screen  900 . Screen  900  is similar to screen  500  in that 7 days of time intervals are shown in a single screen. However, the layout of screen  900  permits larger numbers  905  representing the times, thus making the screen more readable from a distance. For each day  910  only a single set of numbers  905  are required. Above and below each number is an indicator  915 , such as a circle, the indicators above the numbers representing AM times and the indicators below the numbers representing PM times. In between each hourly indicator is a ½ hour indicator  920 . Preferably indicators  920  are easily distinguishable from indicators  915 , for example by size or color.  
     [0042]FIG. 10 is an illustration of an alternate programming screen  1000 . Screen  1000  is divided between channel indicators  1005  and time indicators  1010 . Preferably the first time indicator  1015  for each channel represents the current time. Thus in screen  1000  the current time  1015  must be 1:00 since the next time  1010  following the current time is 1:30. In using this screen, the user scrolls down the screen in a direction  1020  until the desired channel is found, potentially scrolling through numerous pages or screens. After finding the desired channel, the user scrolls in a direction  1025  until the desired recording time is found, also potentially scrolling through numerous pages or screens.  
     [0043] In an alternate embodiment of the invention, prior to initiating recording the programming controller  100  determines if the VCR is in a power on or power off state. If the VCR is in a power on state, when the programming controller determines that it is time to begin recording, it simply tunes the VCR tuner to the selected channel and initiates recording, thus eliminating step  470  illustrated in FIG. 4. If, on the other hand, the VCR is in a power off state, the programming controller turns the VCR on before initiating recording. This feature eliminates the risk of missing a planned recording session due to the user inadvertently leaving the VCR&#39;s power on.  
     [0044] In an alternate embodiment of the invention, after a set of VCR programming instructions has been input into the programming controller, the programming controller determines whether or not the VCR contains a tape. This feature is most easily added to a controller which is integral to the VCR as illustrated in FIG. 2.  
     [0045] In an alternate embodiment of the invention, the VCR programming screen allows the user to select the week for which the VCR programming instructions are to apply. For example, a portion  925  of screen  900  lists weeks  1  through  4 . Therefore if a user wishes to record a ½ hour program at 8:30 PM, a week from tomorrow, the user would first select “2” from portion  925  to indicate that the desired program is not shown at 8:30 PM tomorrow, but rather a week from tomorrow.  
     [0046] Another feature which can be implemented with the present invention is illustrated in portion  930  of FIG. 9. Portion  930  lists three choices for the user: ONCE, DAILY, WEEKLY. If the user selects ONCE, then the VCR programming instructions input by the user will be applied once and then erased from memory. If the user selects DAILY, then every day at the same time the controller will cause the VCR to record the designated time slot until this instruction is erased by the user. If the user selects WEEKLY, then every week at the same time and the same day of the week, the controller will cause the VCR to record the designated time slot until this instruction is erased by the user.  
     [0047] As will be understood by those familiar with the art, the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. Accordingly, disclosure of the preferred embodiment of the invention is intended to be illustrative, but not limiting, of the scope of the invention which is set forth in the following claims.
