Description

[Detailed description of the invention] Program directory for video tapes and cassettes. l-Kikai ■Tatedan According to the present invention, the present invention relates to magnetic tape cassette tapes. retention of information, especially magnetic tape readers/recorders - and the current information on tapes that use magnetic tapes and cassettes for this purpose. Concerning holding formation. According to another view, the present invention A means to facilitate the management, storage, and retrieval of programs stored on tape and the method.

2. Arakiqi group There are two common ways to store large amounts of data over long periods of time: Dumb access and sequence access are known. Random access method The law applies to commonly used long play (LP) record players. , compact disc (CD) drive, video disc drive, and Hard disk drives and floppy disks for use with computers -Used in drives and optical disk drives. All information tion, move the play head to the desired play area of the stored media. accessed randomly by navigating directly to

For the sequence method, the stored information is can only be accessed. Sequence methods are commonly used audio tape drives, video tape drives, and digital audio tape drives. digital tape drives and digital tape drives for use with computers. drive and tape backup cassette drive and analog Used in tape drives. All of these devices use magnetic tape as a storage medium. It is used as a body. The big advantage of tape drives is that they are random analog -Low cost compared to other devices.

There are the following three drawbacks and problems when using magnetic tape.

1. When advancing to a specific location on the tape, the tape is must be advanced or rewound in sequence. In front of the expressway Whether forward or reverse, this is a time-consuming process.

2. The exact content and location of the tape record is unknown.

A random access device indexes the contents to the starting position of the disk (V index information can be stored in the outermost trunk), but the index information is always the index needs to be accessed and the read or write head simply Just skip to the box and read. For magnetic tape, the index The video remains even when recorded in the area reserved for the beginning of the tape ・There will be a need to investigate intelligence, as is currently being done with tapes. Assuming the tape is not at the start position at the time, rewind the tape to the start position of the tape. The time required to do so limits its use. majority Tape owners can title their tapes for quick identification of their programs. I hope to make it possible. Usually, giving a title means This is done by hand writing on the loop or the label of the box. but , the tape may peel off from the box or the label may fall off. part Owners of tapes can record repeatedly on the same tape and use permanent labeling. I don't like business. Computer tapes contain hundreds of records or files In some cases, the index may be written or updated in the box. It's not realistic.

3. The absolute location from which the tape is read or written is usually unknown. Not yet. Most tape drives have a tape drive that shows only relative locations. It is equipped with a printer. For example, if a tape cassette is being played and the next tape - If the cassette is inserted and the tape is removed from the drive without being rewound. Absolute location of the tape in the cassette next time it is played by the drive I don't understand anymore. Relies on writing absolute address marks to tape. Attempts have been made to solve this problem. For example, some recent video The tape has absolute address marks that match the VHS tape's control marks at 1-minute intervals. If you are using the VIIS 7’ Address Survey System (VASS), Ru. In the case of tape-based hard disk computer hack amplifiers, the strip The system model is commonly used, and moreover, a constant stream of data - When blocks (usually 512 hides) are written on the tape, each Locks are normally advanced by one or two address bytes. Therefore , absolute addressing can be used, but is not yet widely used for tape.

Knowing the absolute address is important. For example, five programs (or records) ) are on the tape, each of their starting addresses are known, and the user It is assumed that the user wants to proceed to the start of program 4, location. do. Absolute address at which the tape is fully positioned for reading or writing If the user or drive does not know the and cannot know how to reach the desired record.

These are used to run random access devices on tape drives. It will be important to solve three problems.

Setting an identifying title to a tape introduces other problems. Setting the video title It is well known that alphanumeric information is magnetically placed at the beginning of the tape. This serves as a title, as it can be used to record That will happen. Titles are usually computer-generated and controlled. Recorded in a stream of regular video frames rather than in a roll block. will be recorded. Title quality drops dramatically when multiple tape copies are made do. Also, the title is conveniently written without recording the stream of frames again. Cannot be edited. The prior art system for setting such a title is Stems can be expensive or large. Professional video titling system The system is equipped with the well-known Chyron system and numerous other systems. . Generally these systems are complete combinations of high-resolution character generators. special effects generator for effects such as shadows and italics, video It is equipped with a video interface that generates signals. Such a system , too expensive and complex for home video marketers.

Some video cassette recorders (VCRs) and camcorders may record A simple signal that is superimposed on the video signal or recorded and mixed with the image signal. Includes a simple character generator for displaying pure block letters and numbers. It is listed. A typical camcorder recorder records the date and time. “Date stamp” is added to the video signal as it is recorded. V (J), the character generator will be added to the The program is set to record at a future date, so Programming interfaces like time, date, and time on screen can be used to indicate However, now the VCR character generator There is no simple scheme that can be used as a titling device.

Another problem with prior art titling systems is data entry and editing.

For Chyron systems, a full-size typewriter-style keyboard The card is not suitable for home use and is used at low speeds suitable for inexperienced typists. It is being Title editing allows the title to be recorded onto the tape as a video image is impractical for most home-generated titles. subordinate Therefore, the conventional technology has been limited to the use of magnetic tapes that are stored in sequences. It does not provide a convenient means for generating, storing and editing video titles. Ho Users of video equipment can use internal character generator hardware and VCR remote control. It recognizes the system using the remote control as well, so you can generate the title. It is believed to eliminate the need for complex or expensive hardware to achieve this goal.

Vertical blanking interval (like line 21 field 1 in VB) Encoding program headings in unused portions of a broadcast television signal is a well-known technique. Recently, the federal government's Communications Commission announced that the television industry , create a specification that provides program identification data to line 21 field 2 of the VBI. requested that it be completed. The industry established Mitsubishi on IO 17, 1991. i Electronics America.

Expanded data for Line 21 Field 2 published by Inc. ・We responded based on the specifications proposed for the service.

However, prior art devices do not support VBI for use with magnetic tape directories. Unable to decode program title data from .

The cassette 40 is a cartridge or cassette (hereinafter referred to as cassette) housing. A conventional video tape with magnetic tape 42 packaged in a It's a deo cassette. Housing size and design are different types of recording techniques Basic information based on the tape itself, depending on the technique I have.

Figures 3 and 4 show one of the video tapes in both BETA and VH3 formats. The content of the example information is shown. The tape is divided into three areas. It is. A narrow strip running along the top edge of the tape carries the audio signal This is an audio track 42a to be mounted. The first section runs along the bottom edge of the tape. 2 narrow slip is a controller equipped with a synchronous ("5 sync") control signal. This is Le Track 42c. The intermediate portion 42b raises and lowers the width of the tape at a slight angle. This is for video signals that are recorded in pairs of parallel fields. Well known in the prior art , each video frame 42b has fields A and B, or It consists of two fields known in various ways, such as fields 1 and 2. . In the case of the NTSC protocol, which is widely used in America, each field is is equipped with 262.5 horizontal lines, and a pair of fields is equipped with a single field. It consists of 525 line video frames and is displayed instantly on the video display 50. Create one video picture at a time. Video head drum 13 has Two read/write heads are installed 180° apart, so even numbered labels Ins make up one field, and odd numbered lines make up the other field. B To reduce flicker on the video screen, these fields are Each other projects onto the surface of the cathode ray tube (CRT) screen 50a of the video display 50. It's being brought out. The VCR control logic 21 controls the odd numbered labels of the CRT. scan from left to right and from top to bottom to include odd numbered lines. Start with the field you want to write. As soon as this is done, the beam will even-numbered lines are scanned onto the screen. Ru. When the beam is returned to the top, there is a slight delay called νBl. child The equipment and methods for using these techniques are well known and will not be described in detail here. stomach.

Each tape contains information about program or record name and location. One or more program directories containing the , stored on tape. Video frame 42b or control track Link 42c may also be used to store program directories. . In one embodiment, the program directory is a microprocessor - VCI under control of controller 31? Depends on control logic 21 However, in another embodiment, the control trunk 42c has a space. to the odd or even field of a pair of video fields that are separated by opening the be remembered.

In embodiments, the tape has only one single valid directory and A number of used discs corresponding to the number of times the disc has been played and removed from the VCR. It is equipped with a directory. The effective directory is determined by the marker symbol described later. They are distinguished from used directories by their stem. In another embodiment, the di Each time a directory is read into local RA gate memory, the directory is will be deleted from During the process of ejecting the tape from the VCR, the updated data directories so that only one directory is retained on the tape. It is written back onto the tape at the output position. The disadvantage of this implementation is that the control or Required to screen and erase directories without negatively impacting the audio signal With added hardware and time. One or more directories contain videos ・When stored in a field, the space is opened depending on the number of fields. Directions to selected video fields, such as some odd fields Alterations in the video signal that have a trivial signal can cause slight, visually perceptible changes in the video picture. It will only have as much influence as possible. This is what happens to a person's brain after the image is removed. This is because a visible image remains for a very short period of time (“lingering afterimage”). Once the directory is stored on the control track, it will appear on the video display. control n synchronization pulses (not shown) required for synchronization of will be carried out.

The VB2 section attaches address marks to the tape and connects the recorded program to the tape. It can also be used to facilitate management, storage, and retrieval of files. Implementation Mr. B In this case, a cassette tape is first inserted into a recorder embodying the invention. When input, it is rewound to the starting position and then zeroed to the tape counter. It will be reset. If you encounter VB+ while recording a program, the tape counter - value is registered. The value of this tape counter is in the VB2 part of the broadcast signal. (such as line 20).

The value of the tape counter is like the VHS Address Search System (νASS). Can be written to the control track. Instead, the present invention consists of According to the view, it can be written to the video frame 42b (peripheral (Refer to 3 and 4) Furthermore, if you use ShiB+decoder 400, the program name It also has the advantage of being able to decode both the address mark and address mark.

Updated depending on the tape counter value, RA? I's directory is its current The open file was recorded on tape in the target position and the directory was stored on tape. Allow the tape to rewind slightly to the starting position, then connect the motor and mechanical components. The controller 5 physically takes out the cassette 40.

When a blank cassette tape is inserted or the user enters the program directory. When you wish to change or create a controller, displays 32e or video display 5 for the desired input. 0 to prompt the user. The microprocessor controller 31 is written to the RAM directory 33a for recording on tape when the tape is ejected. Generate human power according to the format required for storage.

The tape is running at its end without proceeding with the tape's directory read/write process. The cassette is moved forward or backward from the ejection position (the tape is There are a number of methods that can be used to It is probably used to set the location of the directory. one dire If only the directory is stored on tape, that is, the directory is If the tape is to be quickly erased after being copied to the Rewind to the start of the file (BOT) and then run a quick probe to scan the directory. The output position is set. Instead, the marker indicates that the directory is whether recorded on a field or control track. is written to the control track near the directory, and this Prompts directory investigation and probes to discover directory location. detected during inspection. Examination and interpretation of control track data can be done using video It is done much faster than it is done in the field.

FIG. 3 shows markers adjacent to directory 112 of control track 42C. 110 and FIG. 4 depicts the video frame 42B illustrated in FIGS. 3 and 4. of the control track 42C adjacent to the field's direction January 16. Marker 114 is drawn.

If two or more directories are stored on the tape and only one is the current directory, When creating a directory, two different methods can be used. First method is illustrated in FIG. In this method, the marker 118 is the same as that shown in FIG. First written in the process of ejecting the tape from the VCR as shown Sometimes (whether on the control track or video field) The data is recorded on the control track 42C near the directory 120. direct When January 20 is effectively read and copied into RAM memory, the second marker -122 is recorded next to the first marker 118 as shown in FIG. 5B. Ru. When a cassette is ejected after playing or recording, a new directory 1 24 along the non-glue marker 126 as shown in FIG. is written to another position in the group. As a result, the tape position of the cassette When the head is moved, it is shown in dotted lines for read/write heads 17 and 19 in FIG. 5D. As shown, the system is conveniently configured to reduce access time. With the fast search being done, a single marker 126 can be used to Check month 24 on the median line. The directory 124 where the location is set is When read by the second marker (not shown), the second marker (not shown) -126.

Instead, marker 130 points to the new directory, as depicted in FIG. is created as illustrated in Figure 68, the directory January 32 is recorded in the next control trunk 42C. But unlike the previous method , when directory January 32 is examined and copied to RA-, marker 130 is , erased as illustrated in FIG. 6B. 2nd new directories january 34 is created, the marker 136 is recorded as [D6C. Therefore, If two or more directories are on the tape and the tape is read/written in Figure 6D. The recording heads 17 and 19 are moved within the cassette as shown by the dotted lines. Even if the current directory 134 is has a marker 136 associated therewith for detection and location of the directory. It turns out.

As explained, for the embodiment of the invention depicted in FIG. (i.e., the location of the tape at the eject point) ) is recorded on a storage device or storage medium, for example a magnetic strip 150. mosquito The mechanism for raising and lowering the set is on the side of the opening, so the magnetic strip The data (i.e. tape location) is detected by magnetic write/sensor head 154. The physics of the cassette loading/unloading drive mechanism to change the magnetic flux generated. is recorded by the magnetic write/sensor head 154 using a magnetic motion.

The loading/unloading drive mechanisms are a component of most VCRs. This is a well-known technology.

Physical cassette movement is shown in Figures 4 and 5, respectively. General horizontal and vertical motion suitable for VCRs using either top-mounted or top-mounted We are preparing for When a tape cassette is inserted into a VCR, the magnetic write/sensor The sensor head 154 receives location information from a magnetic strip. read from to allow easy lookup and location of valid directories.

Instead, the entire directory is written to the magnetic strip on eject. can be caused by the physical movement of the cassette through the head. during insertion by the magnetic write/sensor head 154 using changes in the magnetic flux caused by the can be read.

FIG. 8 shows a video card with a front mounting mechanism for tape cassette 42. This is a pictorial drawing of a set recorder. Each cassette 42 is inserted into the recorder 1. is read from and recorded on the magnetic strip 150 as it is read and removed from the magnetic strip 150. It includes a fixed magnetic read/write head 154 designed to Ru.

FIG. 9 shows a video cassette with a top loading mechanism for cassette 42. ・This is a pictorial drawing of a recorder. Fixed magnetic read/write head 154 As each cut 42 is lowered toward and removed from the recorder, the magnetic a recorder 154 to read from and record on the air strip 150; The position is set to .

Arm 2502 is pivoted by pivot 2510 giving it free vertical movement. is attached to the member 2508. Member 2508 has a free horizontal Another pipono) 2511 that gives motion and adjusts the slight displacement of the tape 2506 Therefore, they are attached to the cantilever 2509 in order.

The head 2501 is configured such that the arm 25o2 is displaced in order to adjust the direction. Even if the tape is shifted when adjusting the tape, it will move parallel to the tape 25o6. 2516 (pivono) 2516.

Lift cam 2512 is rotatably attached to member 2508. , one arm 2513 of the cam 2512 has a spring 2 attached to the cantilever 2509. 514. When the cassette is not present, the spring 2514 Since the arm 2513 of the arm 2512 is lifted up, the head 25o1 can also be lifted up. It becomes. When the cassette is inserted, it is connected to the other arm 251 of cam 2512. 5 is pressed, the arm 2513 is lowered and the head 25o1 is placed on the cassette's magnetic strip. Make sure it goes down towards the lip.

Various other mechanical configurations and arrangements for head 154 and strip 150 are suitable. It is thought that it will be adopted to incorporate various tape/cassette feeding mechanisms. It will be done. From the example, head 154 retrieves information from strip 150. Fixed when the cassette 42 is in the recorder l for reading or writing. A suitable feeding mechanism (not shown) is provided to skim the surface of the strip 150. It can be made portable and programmed using can.

One advantage of the movable head is that the strip 150 can be moved without requiring movement of the cassette. It can be updated by information from RAM 33. Now, it is performed more frequently, such as each time the directory 33a is updated. Directory information is available when the cassette is removed. It is stored even when the recorder is turned off before it is released.

In the case of a fixed magnetic head, it is used to store information. The length of magnetic strip 150 that can be is limited by the distance the cassette can move when it is moved. Data storage and inspection of movable heads Another advantage of the moving head system is that the magnetic head system does not require movement of the cassette. The advantage is that the length of the air strip 150 can be increased.

Details of the video cassette strip 150 and mounting strip are shown in Figures 16 and 17. Illustrated. As shown in Figure 16, a VHS type video cassette A standard video cassette 42, such as a A housing 42 with two and four side walls 204, 206, 208 and 210. Equipped with Typically, the housing 42' is arranged relatively flat and parallel. between the top and bottom walls 200 and 202 in the vertical direction. The distance is less than the radius or length of the top or bottom wall. magnetic Strip 150 (not shown in FIG. 16) is attached to the mounting zone on the rear wall of the housing. 151 or the top of the housing.

The magnetic strip 150 is in a stiff state 149 as shown in FIG. Or the state of rolls or sorting that is cut according to size by the user ( (not shown) and can be arranged. 1 strip each 50 includes a magnetic recording layer 152 and an adhesive layer 156 for attaching the zone 151. ing. For example, the magnetic layer 152 is made of the same material as the magnetic tape 42. and can be attached to any standard tape cassette by the user. Alternatively, it can be pre-attached by the cassette manufacturer. Habo length is 1.5 A strip of video tape that is 1.5 inches wide and 1.5 inches wide has approximately 4 kilobits. layer 15 of the configuration of FIGS. 8 and 9 for storing coated digital data of 2 can be used.

Any of a wide variety of natural or synthetic organic adhesives can be incorporated. teenager In an alternative embodiment, strip 150 is double back to zone 151. - Formed by tape self-adhesion. Therefore, strip 150 can be Since it can be attached to a quasi-cassette, the owner of the cassette can use the directory storage function. can be added to any cassette you have.

Figure 21 shows another embodiment of the magnetic strip. A magnet according to this embodiment The air strip 2101 is attached to the base, like the card 21o2. Ru. The card 21o2 has a push-down area 21 on which the magnetic strip 2101 is placed. 03 is conveniently prepared.

A strip of elastic material (not shown) is attached to the magnetic writing/sensor. To improve contact with the card 21o1 and the magnetic strip 2101, placed in between. The guide, such as groove 2104, It guides the magnetic strip in read/write operations. is provided to card 2101 to ensure movement. Groove 2104 is used to engage the pin of the magnetic head. In addition, each end of the groove is connected to the groove 2. 104 and can be widened to assist the magnetic head pins in mating with the Can also be done. On the other side of the card, the adhesive substrate adheres the card to the cassette. It is given to help people. The sliding cover (not shown) can be optionally given to protect the

The card 2101 according to embodiments reduces the exposure and exposure of the magnetic strip. 22, at the top of the cassette in recess 21o5 can be placed.

Alternatively, a card with a magnetic strip may be used as shown in FIG. It can conveniently be placed in its recess on the rear side of the cassette casing. mosquito When the thickness of the set is not long enough, the magnetic strip relies on two magnetic heads. can be divided into two parts 2302 and 2303 in order to be read as Wear. The card supporting the magnetic strip is depicted as 2301 in FIG.

As depicted in Figures 21 and 22, magnetic tape embodies the present invention. Since the directory is available, the appropriate functionality can be implemented. A mark 2101 is provided to notify the controller.

The mark 2101 is, for example, made of a photoreactive material (e.g. reflective material). light from a light source like a light emitting diode or laser recorder device (or magnetic write/sensor head). (as part of the code).

To facilitate its use with fixed magnetic heads, the magnetic strip 150 is made of magnetized material. It is equipped with two parallel tracks made of wood. The first track is illustrated in Figure 19A. The clock signals are pre-recorded using uniformly spaced clock signals, as shown in the figure. This is the control track that is used. These clock signals are used to read data. Provided to synchronize read/write operations with the second data trunk. It is. The rising edge and falling edge of the Utsuk signal indicate cell boundaries. Ru.

In accordance with a preferred embodiment, the data is modified non-zero mark recording (NRZ- M) method is used to record on the second track. Under this method, bit “0” is the first transition inside two consecutive transitions in the magnetic field of the control track. This is represented by the fact that there is no change in the magnetic field of the two tracks, and ° “1” is shown in the figure. Two successive tranches of the magnetic field of the control track as seen in 19B. It is expressed by a change in the internal magnetic field of the Ginojoon.

The flowchart to Figure 20 shows the logic sequence of the write operation. It is shown in a single way.

Write operations are performed on the directory controller, as illustrated in Figure 7. resident in the controller 30 or separately inside the VCR 17 (not shown). is controlled by a read/write circuit.

It can be specifically implemented by hardwired circuits or software. I can do it. A detailed description of the read/write circuit, however, is well known in the art. So it seems not necessary.

In step 2001, the read/write circuitry performs transcoding on the control track. Wait for Ginojoon to occur. When you encounter your first transinosion, read/write. The write circuit proceeds to step 2002 where it resets the timer and Start.

In step 2003, the read/write circuitry selects the next step on the control track. Wait for the lunge to occur. When a transinosion occurs, the timer The value of is registered and then restarted (step 2004). step At 2005, the read/write circuit registers the timer registered at step 2004. is delayed by a time equal to half the value of -.

Steps 2004 and 2005 are performed for read operations, so The data is measured at the moment when the magnitude of the magnetic field reaches its peak value, as illustrated in Figure 19C. can be sampled. These two steps are can be omitted if the version is performed during a read operation.

In step 2006, the output data bits are examined and the output node is 1”, a signal is sent to the write/sensor head to write the data track. (step 2007). When the output bit is 0”, step 2007 is omitted.

At step 2008, the read/write circuitry determines when the write operation is complete. Determine whether or not the Step 2003 is performed if data remains. It will be carried out again.

A read/write head unit 154 reads the control track. 1st IIPL write/sensor head and read data track It is actually equipped with a second magnetic write/sensor head for reading. 1st magnetic book The read/sensor head responds to changes in the magnetic field along the control trunk. sample the signal received from the second magnetic write/sensor head. generate clock pulses for

As previously mentioned, in the case of a fixed head, the data is transferred to the magnetic strip 150. is written when it moves in the direction of becoming, and when it moves in the opposite direction be read.

Magnetic strips to facilitate read and write operations performed in opposite directions The data written to the 150 data tracks is as illustrated in FIG. 19B. It comes after the header 1901. Header 1901 corresponds to the read/write circuit. provided to synchronize the control track clock signals. Like The header 1901 according to an embodiment includes 24 vias. . After the header 1901, from the data track of the next clock cycle. given to indicate that all read are valid data bits. There is a mark 1902. In accordance with a preferred embodiment, there are two marks 1902. It is equipped with 6 0 bits before the ``' bibinoto''.

This bit pattern was chosen because it is not used to represent data. be done. It is understood that other bit patterns may be used.

The write operation is done in the opposite direction, so mark 1902 and header 1 Mirror images 1902' and 1901' of 901 are each shown in FIG. data field 1903. Moreover, parity Byte 1904 is given after data field 1904 so that each The direction of the magnetic field at the end can be determined.

FIG. 19C shows the second magnetic write/sensor when reading the bit pattern of FIG. 19B. shows the output from the sensor head. Ideally, the second magnetic write/sen Sir Head has two consecutive transitions in Control Tract. Data tracks must be sampled at intermediate points. What a shame In this case, the magnetic strip 150 is connected to the first and second magnetic heads that are misaligned with respect to each other. The data trunk can be read by the first and second magnetic The heads are positioned differently from these ones to read the strips, different The data track may have been written by a different recorder. This results in samples not being sampled at appropriate times.

To compensate for possible misalignment between the two magnetic write/sensor heads, Calibration is performed when the header is read.

With respect to the flowchart of FIG. 20B, the read/write circuitry performs step 2010. Wait for the start of a read or write operation. control track When the first transission is detected (step 2011), the read/write The circuit starts by resetting the timer. In steps 2012 and 2013 , the read/write circuit detects the control track transition. Continue sampling data tracks until

When the field of a data track is formed by a series of 1” bits, The data trunk transitions are two consecutive transitions on the control track. occurs inside a transition. data track transitions Once detected, the control track's first transition and data track The time delay TI between rack transitions is measured. control tiger The blocks are read continuously until the next transition is detected. 1st and The time difference Tc between the second transitions is calculated (step 2014).

For more accuracy, steps 2012-2014 should be repeated N times. Therefore, the average value of TI and Tc can be calculated. Equal to TI/Tc A positive value is calculated.

lm20C is a logic controller for reading operation of magnetic strip 150. It shows Kens. In step 2020, the read/write circuitry Waiting for the detection of a transnosion on the track.

When a transition is detected, the read/write circuitry indicates that it starts a timer. Step 2021 is entered to reset and start. In step 2022, read /The write circuit waits for another transition on the control track. . When such a transition is detected, a timer is read and then reset. time between two consecutive transitions on the control track. The difference Tr is calculated (step 2023). In step 2024, read/write Since the internal circuit waits for the delay, the data traffic is sampled at its peak value. can be done. FIG. 2 OA Write Operation Steps 2004 and 20 05 is executed, the delay becomes Tr” (TI/Tc). When steps 2004 and 2005 of the section are not performed, the delay is (Tr/2 ) +Tr (TI/Tc).

At the end of the delay, the output of the data head is sampled (step 2026 ). When the output of the data head is equal to the value of its last clock, is output (step 2028). Alternatively, the output of the data head is If changed, a 1'' bit is output (step 2029).

In yet another embodiment, a thin erasable programmable read-only memory ( EFROM) or erase-rewrite read-only memory (EAROM) 151 can be placed outside the cassette.

Microprocessor controller 31 and VCR control logic 21 also reads the control and audio controller, and the head logic 11. Directs the head 12 to read the directory from the control track. Execute when the directory is there. Directory read/write at insertion point not near the recording head (if the tape has been moved within the cassette case). In block 53A, the microprocessor controller 31 controls the VCR. Via control logic 21 and motor and mechanical controls 5 , rewind the tape 42 toward BOT, and also rewind the tape 42 toward the BOT and Conduct a high-speed survey of troll trucks. When the end of tape (EOT) does not appear , if the marker is not found, the microprocessor controller 31 , a blank directory, and a directory of the directory controller 30 displayed on either the video display 32e or the video display 50.

On the other hand, if a directory is found in this case, block S4 The file is read into the RAM 33. The marker is erased in block S5. substitute Finally, both the directory and the accompanying marks are erased from the tape in block S5. Ru.

At block S6, microprocessor controller 31 connects logic 21 to Read/write heads 17 and 19 cause control 5 to rewind the tape. is located immediately before the directory. In block S7, the current location of the directory The value sets the position logic and tape counter of counter 9. It is used to At block S8, the directory checks the user's confirmation, edit, or by display 32 or video display 50 for input. Is displayed. The method now enters block S9 (FIG. 2D) to further prompt the user wait for instructions. When the PLAY button 3b is actuated by the user, the process is blocked. Continue with block 518. In block S19, the VCR performs all recording or reading. That is, by playing the tape and displaying the video image on the video screen 50a. Ru. If the 5TOP button 3C is actuated instead, the micro Processor 31 causes logic 21 and control 5 to stop the tape. tape does not necessarily have to stop at the end or start of the program.

Block S24 blocks when the EJECT button 3e is actuated by the user. Issued from Ku59. In block S25, micropro sensor controller 31 checks whether the directory 33 exists in the RAM 33. . When the directory is not in RAM, block 330 is processed and cassette 4 o is retrieved without writing the directory to tape. This is the tape doesn't have a directory and, by the way, the user didn't create it. , or the user deletes the directory from RAM via input/output device 32. Occurs when

Let us assume that the directory exists in RAM 33. My block S26 The processor controller 31 is the CURRENT LOC of the RAM 33. with the position logic and the current tape location value of the counter 9. Update. At blocks 27 and 28, microprocessor 31 connects logic 21 and Cause control 5 to begin moving the tape forward. In block S27 , microprocessor controller 31 provides direct input to logic 21 and 11. record one marker on the control track stored on tape. Let it be recorded. At block 528, microprocessor controller 31 directory from RAM 33 to the tape control trunk near the marker. Move to.

At block 512, the microprocessor controller 31 is the current tape ゛ ゛ ゛ ゛ ゛ ゛ ゛ / Compare the program location and direct LOG for program input by the user. Ru.

When the program is in front of the tape, the microprocessor controller, 3 1 tells logic 21 and control 5 to block the tape to the desired location. Proceed with lock S13. Or, if the program has already set the current location. If you have passed the microprocessor bar, logic controller 21 and control 5 After the program is read and displayed on the screen 50a, block S1 4. Rewind the tape to the desired location.

If the address mark is stored on the VB2 copy of the cassette tape, the survey option The operation is performed between the current address mark and the address mark of the target program. This can be implemented by calculating the difference between the response marks. address If the track is written to a video frame as described above, the VCR control The control logic 21 can obtain these values via the VBI decoder 400. Yes (see Figure 12). Current address mark and target program The difference between the address marks of the program is set in the position logic and counter 9. (See Figure 12). Fast forward or fast rewind operations based on the sign of the subtraction. ration is carried out. When the tape counter reaches zero, fast forward or The fast rewind operation is stopped and the PLAY operation is started. and start playing the tape.

Next, use a blank tape cassette or pre-coated tape with no directories installed. The system of Figure 1 in which a coded tape cassette is inserted into a VCR. Let's think about the operation.

The directory controller plays the tape as a regular tape. or to allow the user to create directories on the tape. ing.

Take a look at Figures 2A and 2B. The cassette is inserted into the VCR using Pro Tsuk S1.

The microprocessor controller is assigned from the last tape in block s2. The remaining directory 338 of the RAM 33 is deleted.

At block S3, the microprocessor controller connects the logic 21 and Have Troll 5 and Logic 11 read the tape forward until the directory is exists on the control track of the current tape location. Let them decide.

When the directory does not exist on the tape at the insertion point, the program Entered Block 33A, which is being investigated for [Buylev] If the microphone cannot be connected, a blank directory will be displayed and the sequence will not be connected to the microphone. The controller 31 is waiting for function selection. s9 (Figure 2D).

The data for controlling the programs stored in the RAM 33 is stored in the directory 33a. Send with. The program displays the heading information in the directory program. It is stored as a program title and displayed on the display 50. Heading data is The directory is sent at or just before step 1408, so the directory When the directory is displayed in step 1408, the heading data is immediately appears on the screen. The user can then edit the heading and make it as required. You can adjust it by

The headline data is broadcast by the broadcasting TV station in a continuous stream. Set to TV signal. VCR1 users can store without any additional hardware. Unable to stop or slow down the ream. Therefore, depending on the antenna 420, The program title may not be the first heading data received. . This problem can be solved by coupling the data expander memory 430 to the decoder. It can be solved accordingly. received by the decoder under the control of the decoder. All received heading data is stored in the heading buffer and sent to the control. ・Continuously output to logic. Each heading data word is placed in a directory Once displayed, the user can press the ENTER button to receive the word. , save it as the program title. Buffer size and decoder In a period based on the rate of data received by , it can be recalled by the user and is safe as a program title. It remains in the pamphlet where it can be removed. When the buffer is full, the received commands Any additional data will overflow and overflow the earliest received word. result in loss. If a large enough buffer is used, this The influence of bar flow is not a problem. Review and save buffered data The ability to save printed titles is stored in RAM on a computer programmer. can be controlled by a program or subroutine.

Information transmitted in VB2 part (e.g. title, subtitle , program identification) is displayed in real time or the program in the directory is displayed in real time. Not only can it be used to generate video titles, but it can also be used to create It can be utilized to further advance the operation of R. For example, legend By monitoring the transmitted title, the VCR will automatically The end of the program can be detected and recording can be stopped. Also transmit the title By monitoring the VBI section used to Temporarily stop the VCR when a change in the program section is detected, making it unrelated to the program. It is possible to filter segments (e.g. commercials) (when recording a program). can.

As mentioned above, each video frame of the broadcast signal consists of field 1 and field 1. It is split into two fields, referred to as field 2. In North America, each The field is 2621/2 for a total of 525 horizontal lines per frame. It is composed of The first 21 lines of each field are vertical blanking intervals or or VBI. Normally, line 21 of field l would be used to transmit closed heading information used in It's been coming.

Instead, line 21 in field 2 will contain the program's channel number or Broadcast program identification information such as date, time, title, and assignment category broadcasting for a wide variety of expanded data services, including is considered for.

This data is broadcast at a relatively high repetition rate before being broadcast, so data detection Enables a decoder suitable for Therefore, in the system of FIG. 12, decoder 4 00 each frame program identification information in buffer 430. can be designed to receive and store from line 21 of field 2 of the program. Wear. With appropriate logic, the program title and other information applications may be automatically stored in directory 330 without user intervention. I can do it.

remote shuttle control, character generator, directory control The control program stored in the roller is stored in the program directory. It can be used to create bird video titles. embodiment consisting of 14A and 14B, the method of FIGS. 14A and 14B is similar to the method of FIG. used in conjunction with screen video displays. Illustrated in Figures 148 and 14B The system is in step Sll or sI6 of 1ff12B, Step s78 to Figure Io or Figure 11, or Step Sll and 3 of Figure 11B Called when you turn 16. When these steps are performed manually, the system is shown in Figure 14. coupled to and stored in a microprocessor containing instructions for carrying out the steps of A; is placed under the control of the program being run. The control is The system tests whether the directory display is selected. The process proceeds to step 14o4. If not, control returns to step 14. 06, the data entry mode of [D14A ends.

Otherwise, the control indicates that the directory display 32e is - Proceed to screen 1408 illustrated on the screen. The display is alphanumeric Keyboard 1'50b representation at the top of the screen, video title 50g below. It takes the format shown in FIG. 14C, which is included in the section.

Keyboard expression 50d is t11! QWEl? TY-style typewriter I'm with the keyboard and billions. The plurality of columns 50e each include a plurality of single characters 50f. Is displayed. Character 50f is the standard type of QWERTY-layout keyboard. Matches the writer key label. Originally, the title 50g was overall It is blank. Character spaces that can be used to fill out the title as needed. The space is represented by adjacent squares or rectangles as illustrated in Figure 14C. can be

The controller is pressed with the remote control unit 7) 1300. The process proceeds to step 1410 where the system waits until the

When cursor key 1305 is pressed, control advances to step 1412. the on-screen cursor is moved to the new location. That's right If not, the control determines whether the enter button 1303 was pressed. If so, the system proceeds to step 1414 to test. In that case, the controller The troll proceeds to step 1416 and selects the cursor keyboard representation 50d. The character "Q" is moved to the first column 50e. Control is cursor key 13 At step 1418, the system tests whether 05 was pressed. You can proceed.

If so, control is passed to step 1422 and the cursor is moved to the keyboard. is moved to the next character of the code expression 50d. As required, the current character is 50 Illustrated in highlight or reverse video, as represented by the letter C in j be able to. If not, control continues to step 1420. , the system tests whether the jog shuttle knob has been moved. Ru. In that case, control returns to step 1422 to move the cursor. You can proceed. If not, control advances to step 1424 and The system tests whether the enter key 1303 was pressed.

In that case, the user can change all the highlighted characters 50j to the current title 50g. This indicates that he wishes to be given a great sword by the character 50k. Therefore, the control The troll sees that the character 50j is copied to location 50k and calls it the normal By displaying it on video, it is routinely "frozen". control is a statement To advance the character position cursor 50k to the next position, step 14 Proceed to 22nd.

Otherwise, control passes to step 1428 and the system: Test whether menu button 1304 was pressed. Not so If so, control is returned to step 1418.

If so, the user will be notified that the displayed title has ended and the user has This means that you are specifying that you want to save the file to a directory. Therefore, the control Troll is the title shown in the diagram on 50g. The program title is copied to one of the program title locations in RAM 33. Proceed to step 143o. Control continues to step 1406. So end the title entry.

FIG. 14B shows a keyboard representation cursor as shown in position 50j. It shows you how to proceed with the process. The entire keyboard 50d has multiple columns 50e. , so you can press the command (cursor keys or jog • using shuttle knobs) requires special handling at each end of the row. For example, At step 145o, the system determines whether the left arrow cursor key is pressed or Test whether the jog shuttle knob has been moved to the left. In that case, The next task (step 1452) is to select one character whose current character position is column 50e. That is, the current character is on the leftmost side. , whether A or Z Testing. In that case, the control will allow the system to take multiple possible steps. handling the overflow condition by performing one of the steps 145; You can proceed to 4. If necessary, the system simply closes the cursor without doing anything. You can freeze the file at the left end of the column. Instead, the cursor is placed at the rightmost point in the same column. You can jump to For example, if the current character is "Q" and the user moves the left arrow cursor When you press the key, the cursor jumps to the last letter “P” in the column. Seem. Additionally, this method can be used to “wrap around” the previous Jump the cursor to the end of the column. Therefore, the cursor is located at the character “°A” When the user presses the left arrow, the cursor will move to the letter “P” in the top row. You can jump. Any of these steps may proceed to step 1454. Can be done. Otherwise, the current cursor position is in the middle of the column. , control is advanced to step 1456 and the cursor is moved to the left. be moved.

Similar steps 1458.1460.1462.1464 to the right handles cursor movement. In this case, the overflow in step 1462 results in freezing the cursor and moving it to the next column, etc.

A similar process is performed on the PC, as illustrated in steps 1466-1476. Can be performed for the "down" arrow cursor key. rap around The code can be terminated. For example, when the “up” arrow button is pressed, the cursor If the cursor is located in the first column 50e, the cursor may be jumped to the third column. can.

As is well known in the art, the keyboard representation 50d is unique to the character generator circuit 23. By commanding a specific character to be output to a specific screen position. can be created by Therefore, the microprocessor-controller 3 1. Enter the ASCII code for the desired screen position coordinates and characters. By giving a character to the VCR control logic 21, The control logic can instruct this These parameters are sent to the character generator via a command signal.

The character generator receives parameter data and creates a character focus map. Search from character ROM and control appropriate display information. Return to roll logic 7ri. The control logic uses character information into the output video signal and send it to a video display. character ze This step commands the generator to output video characters to the display is a well-known technique.

Using the steps above, the Jog Shuttle Remote will perform instantaneous data entry. functions as a reunit to create character instants suitable for video program titles. It is possible to promote time selection.

Another method of creating video titles is illustrated in Figures 15A and 15B. vinegar Steps 1502-1508 are the same as steps 1404-1412 to FIG. Ru. Proceeding to step 1404, the display illustrated in FIG. is displayed on the video screen by the character generator unit.

As illustrated in FIG. 15B, the °°scroll'° display 50c is with one or more title lines 50g, each containing a plurality of characters 50h. We are prepared. While entering the title, one of the characters 50h is shown as 50m. is highlighted. The highlighted text is the “cursor position” in the title. ” is shown.

When a new title is entered, the display in Figure 15B appears, then the Control proceeds to step 1510 of FIG. 15A. Cursor 50 is on Moved to the first (leftmost) position of the screen title. Conte The role then returns to step 1512 to display the current character at that location. You can proceed to First, the current character “A” appears in the leftmost position of the title. 'become. Controls are moved by the arrow buttons or jog shuttle knob. The process proceeds to step 1514 where the system tests whether or not the data has been verified.

If so, control passes to step 1516. The current character is ′Z゛ma or “A”, special processing is required. When the current character is “Z′′, the right side If the button has been pressed, the cursor changes to ° “A”. Similarly, the current character If the left button is pressed when is "A°", the current cursor changes to "Z".

These steps are affected in step 1518. Otherwise, the control Roll occurs when the left or right button (or jog shuttle knob) is pressed. Proceed to step 1520 where the current character is incremented or decremented based on whether It will be done. Then the control now steps 15 to display the cursor. Proceed to 12. In real time, the user can press the arrow buttons or jog Instantaneous change from A” through each letter as long as the torque knob is activated to view the characters at the current cursor position.

Controls when arrow buttons or jog shuttle knobs are not activated. is advanced to step 1522, and the system test whether it was done. In that case, the user can freeze and save the current character. I would like to. Therefore, the control controls the currently displayed character (and the rest of the controller) is coupled to a microprocessor-controller. Proceed to step 1524 where the process is saved to a memory location. car In any case, the Sol will be used next, as illustrated in step 1525. The cursor can be advanced to the available cursor position. After the cursor has been advanced, The current letter of the position is displayed, and as previously mentioned, this becomes the letter “A”.

When “Enter” was not pressed, the control was set to Menu Button 1 The system tests whether 304 was pressed, step 1526. You can proceed to Otherwise, control is returned to step 1512.

In that case, the user wishes to save the entire title. Therefore, the control The overall title displayed is the program in the directory 33a of RAM 33. Proceed to step 1528 to save to one of the ram title locations. It will be done. Title entry is complete and control ends at step 1530. Complete.

Therefore, using the method of FIG. 15A, instantaneous input of video titles is possible. . Each character position is processed sequentially and the cursor moves from character to character. Proceed with At each letter position, the display first shows the letter “A” and an arrow When the button or jog shuttle knob is actuated, it instantly advances to the alphabet.

The title is not detected from the broadcast signal and the title is also input by the user. A default title will be inserted into the directory when it is not. Default The root title indicates the channel on which the program is received and the channel on which the program is recorded. It is equipped with information such as the date and time.

The cassette insertion used here is compatible with any mechanical tape carrier on the VCH. Manual insertion of the cassette into the cassette and reading near the head 13.15.17°19 This does not include any movement caused by the VCH of the carriage cassette relative to the position. Ru.

The directory controller 30 stores records stored on tape cassettes. extended in accordance with the present invention with further features to facilitate management of the . These additional features will now be described with reference to FIGS. 18A and 18B.

The flowchart in Figure 18B shows that when the directory is displayed in Figure 18A, the shows further options available to users.

When the user activates the cursor movement key, step 1801 enters be done. The pointer points to the entry (or entry the microprocessor to point to the directory 33a (internal field). is given to the server controller 31. Created by cursor movement keys When moved, this pointer also moves correspondingly (step 1802).

When the ERASE button is activated (step 1803), the directory The controller 30 uses the information formula from the directory 33a to program location and erase the program from tape 42 ( Step 1804). After the program is erased, the directory 33a is Entries can be emptied or used to record new programs. (step 1805).

In addition to the normal erase operations described above, the directory controller 30 allows users to “fast erase” programs. This operation is started, a preset key pattern or sequence (special 5P ERASE” key) (step 1806). Directory controller 30 performs an erase operation on tape 42. Simply disable the corresponding entry in directory 33a without actually doing so (Step 1805).

For example, the invalidation of step 1805 can be performed by This can be implemented by setting the "°" bit.

Recording operations can be performed in two different modes. 1st mode According to the command, the cursor is moved to select an entry from the directory 33a. be done. Recording operation starts from keyboard after entry is selected (step 1807), the directory controller 30 A program is recorded on the tape section corresponding to the entered entry (step 1808). ). After the program is recorded on tape, the directory 33a is updated ( step 1809).

The second mode of operation allows the user to perform high speed recording operations. When you activate a preset key pattern and sequence for 0) Begins. Directory controller 3 with high-speed recording operations 0 searches for an empty entry long enough to record the program (step 1811). The optimal entry, e.g. its length is closest to the length of the program. The operation can also be implemented such that a new entry is selected. entry is selected (step 1813), the directory controller 30 Record the program there (step 1813) and also save the directory 33a. It is updated accordingly (step 1814).

Directory 33a provides the user with the title of the program being shown on the television. Gives you the option of recognizing the title. This operation is preset. When initiated by activating the key pattern (step 1820), the director The tri-controller 30 has a VCR broadcasting program or recording. Find out whether the program shows. VCR broadcast program and the program is transmitted as a broadcasting signal (in the VB 2 part mentioned above). At times, directory controller 30 generates titles from broadcast signals. and displays it on the television screen (step 1B22). on the other hand, When the VCR is playing a recorded program, the directory The troller 30 searches the directory 33a for the title and screens it. displayed on the screen. (Step 1823). In a preferred embodiment, a timer is installed in the directory controller 30, so the title is 5 seconds. It is later removed from the screen (step 1824).

The user has a system data file that stores the directory of the selected tape. Like the Lear 33B, you are also given the option to create a library in memory. There is. When the tape is inserted into the VCR, the user can select the preset key pattern. 'Add Library' option by activating a button or sequence. Operation can begin (step 1832). “Add Li In response to the “brary” operation, the directory controller Add the directory of the group to the library (step 1834).

The user can also perform library operations (step +830). . List of tapes stored in the library under this operation is displayed (step 1831). Optionally, the first The program title is displayed along with the tape title.

24G shows a user interface of a controller in which the present invention is specifically implemented. 3 is a flowchart illustrating the interface and operation of the software;

Looking at Figure 24^, the controller of STEP 2401 has a cassette tape. Checks whether it has been inserted. A cassette tape is inserted block 2402 when not present and a controller button is activated. is input.
