Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tape cassette having a memory means for storing information regarding recording on a tape cassette, and a video tape recorder using the tape cassette.

[0002]

[Prior art]

 The conventional video tape recorder will be described below.

First, a video tape recorder with a camera (hereinafter referred to as a movie) will be described. In recent years, movies have become very popular in homes, but they have not been fully used yet. Most of the time, we shoot a few times a year, and the current situation is to play back the video shot without any editing work.

Of the editing work, the title screen creation will be described first. Regarding the creation of the title screen, the movie itself has a function to store the title screen, but it is a method of storing the title screen in the main body beforehand and mixing it with the video at the time of shooting. Other devices for creating titles are also on the market, but they are used only by people who have a hobby of some editing work.

There is post-recording work as the second editing work. It is the work of adding background music suitable for each scene and adding narration.

Although the editing work has been described above, even if only this work is performed, it is difficult to make an interesting work without considering the entire structure. All I have to do is shoot at the time of shooting, and it is difficult to shoot while considering the overall structure unless we have experience. I don't know how long it should be when shooting. When I play it back, I often feel that the shooting time is actually short.

Next, a stationary video tape recorder (hereinafter referred to as a table) will be described. There is a timer reservation function as a general recording function on the table. The current timer reservation data uses the memory function attached to the main unit. I do not know at all what is recorded on the tape cassette of the order etc.. Also, the tape position must be adjusted in advance to the position where you want to record.

[0008]

[Problems to be solved by the device]

 However, in the above-mentioned conventional method, when creating a title screen, it is quite troublesome to store the title screen in advance even if the movie body has a title screen creating function. I cannot afford to select the title screen of. Dedicated title-creating devices are also on the market, but they are expensive for the frequency of use and are currently only used by people who have a hobby of editing.

The post-recording work is also a work that requires a considerable amount of time, and is currently performed only by those who have a hobby of editing work.

Video editing is generally difficult to make an interesting work without considering the overall structure. It is difficult to shoot while thinking about the overall structure when shooting, unless you have experience. I don't know how long it should be when shooting. When I play it back, I often find that the shooting time is actually short.

Further, the reservation data of the timer reservation of the table uses the memory function attached to the main body. For this reason, the tape is inserted into the tape cassette inserted in the main unit at the scheduled recording start time. In other words, it may happen that the tape is not recorded at the tape position of the tape cassette that I intended. It is possible that an important program may be accidentally deleted by overwriting.

[0012]

[Means for Solving the Problems]

 In order to solve this problem, the video tape recorder of the present invention records video information related to each scene predicted to be recorded on a tape, and the start tape position and title of each scene predicted to be recorded in advance. When the tape cassette is equipped with a memory means for storing the name, the start tape position of the video information and the end tape position thereof, and the erroneous erasure prevention information for each video information, and performing the recording operation using the tape cassette. In addition, the recording start date and time of each scene, the tape position of the last recording end point of each scene, and the recording date, start and end time, start tape position, and recording channel are written in the memory means as a recording reservation. Reading means for reading information stored in the writing means and the memory means, a key input device for selecting a recording position, and a selected recording position Control means for transferring the tape with the tape, the tape position at the final recording end point of each scene, and the start tape position of each scene stored in the memory means, and the means for reading and non-recording portion to automatically fast-forward run. The control means and the reading means read out the date and time at the start of recording of each scene and automatically play back the recorded data in the order in which they were recorded, and the read-out means recorded recording date, start and end time, start tape position. Also, the video tape recorder is equipped with a control means for reading the recording channel and transferring the tape to the designated recording position for timer recording.

[0013]

[Action]

 With the above configuration, in the tape cassette of the video tape recorder of the present invention, the video information related to each scene for which recording is predicted in advance is recorded on the tape, and the starting tape position of each scene for which recording is predicted and The title name, the start tape position of the video information and the end tape device, and the erasure prevention information for each video information are stored in the memory provided in the tape cassette. When performing a recording operation using a tape cassette, when the recording position is selected with the key input device, the starting tape position of the selected recording position is read from the memory and the selected recording position is cued. When recorded, the recording start date and time of each scene and the tape position of the last recording end point of each scene are written to the memory. When playing back the video recorded as described above on the tape cassette, the tape position of the last recording end point of each scene stored in the memory and the start tape position of each scene are read and no recording is performed for that section. Automatically fast-forward the part. Furthermore, the date and time at the beginning of recording of each scene stored in the memory can be read out and automatically reproduced in the order in which they were recorded. Also, by recording the recording date, start / end time, start tape position, and recording channel in memory as a recording reservation, it is possible to record at the desired position simply by inserting the tape cassette.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a video tape recorder (hereinafter referred to as VTR) of the present invention, in which 1 is a tape cassette and 2 is a tape cassette attached to each scene of the tape cassette. Electrically erasable and writable read-only memory (hereinafter referred to as EEPROM) that stores the start and end tape positions, title name, recording start date and time, and the like, 3 is for writing and reading information from the EEPROM 2. A key input device 4 for VTR operation and recording position selection, a control head 7 for recording and reproducing control signals, and a control signal for writing and reading control signals to and from the tape 6 via the control head 7. The recording / reproducing circuit 8 and a tape drive for moving the tape. It is composed of a dynamic circuit 9 and a microcomputer 5 for controlling the above system.

FIG. 2 is a schematic diagram showing a recording state on the tape of the first embodiment of the VTR of the present invention, and A to D are areas in which images related to the contents of E to H are recorded in advance. Is.

FIG. 3 is a schematic map diagram of a semiconductor memory showing a first embodiment of the VTR of the present invention. In this figure, a memory having a storage capacity of 1 Kbit is taken as an example, and the vertical axis is the lower address 4 bits of the memory and the horizontal axis is the upper address 4 bits of the memory. In the row where the upper address is accidentally addressed, data relating to the video recorded in the areas A to D of FIG. 2 is stored. That is, the data of the video recorded in A of FIG. 2 is stored in the row of the upper address 0. Similarly, the data of the video recorded in C of FIG. 2 is stored in the row of the upper address 4, and the start tape position 00, 15, 05, 00 of the area C of FIG. In the addresses 45 to 4F, nine characters of the candle service, which is the title of the area C in FIG. 2, are stored in the character code. The address 44 is a storage area for flag information, and in this case, three flags of recording, title, and erasure prevention are set. In other words, this flag stores title information in the area after address 45, and the video is actually recorded in the area from this start tape position to the next start tape position, and this area is overwritten. It means that the area cannot be erased by.

The rows of which the upper addresses are odd addresses store data relating to the images recorded in the scenes E to H of FIG.

FIG. 6 shows a recording waveform of a control signal, a reproducing waveform, and a recording format of various data, which is shown in FIG. 6A when one cycle of the control signal is 100%. As shown in FIG. 6B, a signal whose high level (hereinafter referred to as H level) period is about 60% is a “0” pulse, and a signal whose H level period is about 27.5% is “0” pulse. When recording various data on the tape 6 with 1 "pulse, the above-mentioned" 0 "pulse and" 1 "pulse are used in the data area in binary according to the specifications shown in FIG. 6C. It is recorded by a so-called BCD code that expresses a decimal number. Using this method, the control pulse is measured and the time code indicating the tape position from the tape start is recorded on the control track of the tape 6. Read the time code from the 6th control track and search for the desired tape position.

When the user actually records, the images related to the scenes E to H in FIG. 2 are already recorded in the areas A to D in FIG. Based on the title names of ~ D, images suitable for the title are recorded in the areas of E ~ H in FIG. At this time, when the recording position is selected by the key input device 4 of FIG. 1, the start tape position of the recording position selected from the EEPROM 2 of FIG. 1 is compared with the time code recorded on the reading tape 6 and the result is obtained. Then, the tape drive circuit 9 moves the tape to the start tape position of the target recording position to automatically perform cueing and put it in a recording standby state. The user can then record from there. When the recording is completed, the date and time when the recording is started and the tape position where the recording is finished are written in the EEPROM 2 in FIG. Then, the recorded / unrecorded recognition flag is recorded. When multiple scenes are recorded in the same area, such as when recording is paused, the date and time at the start of recording is the date and time at the start point of the area, and the end tape position is the last recording end point. To be done. In other words, the recording end point is rewritten each time a recording is added.

When reproducing the tape cassette recorded in this way, the user can select either normal reproduction or automatic reproduction by the key input device 4. Normal playback means playback that is simply played back, and automatic playback means playback that reads the recording date and time of each area from the EEPROM 2 and plays back in chronological order. At this time, the previously recorded images related to each scene are also reproduced in the recording order. That is, if E to H in FIG. 2 are recorded in the order of G, E, F, H, the respective areas are reproduced in the order of C, G, A, E, B, F, D, H. When normal playback is selected, playback is performed in the order of A, E, B, F, C, G, D, H. In both cases, the recording end points of the areas E to H in FIG. 2 are stored in the EEPROM 2, so the time code recorded on the tape 6 is read and the tape is automatically reached when the tape actually reaches the recording end point. Then, the beginning of the next area to be reproduced is read from the EEPROM 2, the time code actually recorded on the tape 6 is read from the tape, and the beginning of the area to be reproduced next is searched and reproduced. End Also, it is not necessary to record in all areas when recording. Since the recorded / unrecorded flag is stored in the EEPROM 2 in each area of E to H in FIG. 2, if there is an unrecorded area, that area is skipped to the area to be reproduced next without being reproduced.

By performing the recording / playback operation as described above, the user can enjoy a story-like image in which each scene has a title screen without any troublesome editing work. In the areas A to D in Fig. 2, not only a simple title screen but also scenes that are usually difficult to shoot are included to create powerful works.

Further, since the areas A to D in FIG. 2 are areas that cannot be erased, even if the tape is once recorded and used, all the contents recorded on that tape cassette are duplicated on another tape cassette. By forcibly setting all the recording / non-recording flags E to H of No. 2 to the non-recording flag by the key input device 4, it is possible to logically set the non-recording state even if actually recorded. is there. By this method, the deck judges that the area is unrecorded, and it is possible to newly record the area. In this case, as the recording end point, the final recording end point of the new recording is stored in the EEPROM 2, and even if the image used at the previous time remains, that part is judged as a non-recorded part and is not reproduced. Therefore, if you have one tape cassette for each event such as Shichigosan, wedding, athletic meet, and entrance ceremony, you can use it again and again. The same tape can be used repeatedly every year for athletic meet tape cassettes.

Further, this tape cassette is not only an off-the-shelf product, but it is also possible to create a tape cassette by itself from a tape cassette on which nothing is recorded. In this case as well, by using the erroneous erasure prevention flag, once the tape cassette is created by itself, the original tape cassette created by itself can be used again and again.

Next, a second embodiment of the present invention will be described. FIG. 4 is a schematic view showing the recording state on the tape of the second embodiment of the VTR of the present invention, and J to M are areas in which the images related to the contents of P to S are recorded in advance.

FIG. 5 is a schematic map diagram of a semiconductor memory showing a second embodiment of the VTR of the present invention. In this figure, a memory having a storage capacity of 1 Kbit is taken as an example, and the vertical axis is the lower address 4 bits of the memory and the horizontal axis is the upper address 4 bits of the memory. The rows having even addresses in the upper address store data relating to the video recorded in the areas J to M in FIG. That is, the row of the upper address 0 stores the data relating to the video recorded in J of FIG. Similarly, the row of the upper address 4 stores the data relating to the video recorded in L of FIG. 4, and the addresses 40 to 43 have the start tape position 2,00,00,00 of the area of L of FIG. In the addresses 45 to 4F, 7 characters of the My Home language, which is the title of the area L in FIG. 4, are stored in the character code. Address 44 is a storage area for flag information, and in this case, flags for recording, title, and erasure prevention are set. That is, the title information is stored in the area after this, and the video is actually recorded in the area from this start tape position to the next start tape position, and this area cannot be erased by overwriting. It means that it is an area. The row having the upper address of odd number stores the data regarding each program of P to S in FIG.

Reservation for recording is performed using a row whose upper address is an odd address. The recording date, recording start time, recording end time, recording channel, and start tape position are stored. Two flags, reserved and table, are set at the time of reservation in the flag storage area where the upper address is an odd address and the lower address is 4. The reservation flag indicates that recording is reserved as indicated by the data stored in the lower address area 5 and below, and the table flag indicates that the data stored in the lower address area 5 and beyond is table deck data. It is shown that. Recording will start if the tape cassette is inserted in the deck at the reserved time while the reservation flag is set. Conversely, if the reservation flag is not set even when the reserved time is reached, recording will not be performed even if the tape cassette is inserted in the deck.

Actually, when the tape cassette is inserted into the deck, the flag information is read from the EEPROM 2, the reservation time is read if the reservation flag is set, and the start tape position is read 1 minute before that time. Transfer the tape to the position. Then, the channel information is read from the EEPROM 2 and recording is started at the reserved time. Recording is ended at the end time, the reservation flag in the flag information storage area of the EEPROM 2 is reset, and the recording flag is set.

With the above-described method, reserved recording is performed at the designated tape position. If this method is used, even those who were not able to make the conventional scheduled recording settings can simply record all the broadcasts of the program they want to record in a tape cassette by a third party, without the need for cueing operations. Scheduled recording can be done simply by inserting a tape.

Although the VHS standard VTR has been described in the present embodiment, the VTRs of other standards should record data by superimposing the video signal on the tape based on the standard in the same manner as in the present embodiment. It is possible to obtain the same effect by.

In this embodiment, the time code for measuring the control pulse is used as the data indicating the tape position, but the same effect can be obtained by using the data indicating the absolute position of the tape such as the remaining tape value. Is.

[0032]

[Effect of device]

 As described above, in the tape cassette of the video tape recorder of the present invention, video information related to each scene for which pre-recording is predicted is recorded on the tape, and the start tape of each scene for which recording is predicted in advance is started. The position and its title name, the start tape position and the end tape position of the image information, and the erasure prevention information for each image information are recorded in the memory provided in the tape cassette. When performing a recording operation using a tape cassette, if the recording position is selected with the key input device, the starting tape position of the recording position selected from the memory is read and the selected recording position is cued. When recorded, the recording start date and time of each scene and the tape position of the final recording end point of each scene are written to memory. When playing back the video recorded as described above on the tape cassette, the tape position of the last recording end point of each scene and the start tape position of each scene stored in the memory are read and the unrecorded part of that section is automatically recorded. Dynamically fast forward. Furthermore, it is possible to read out the date and time at the start of recording of each scene stored in the memory and automatically play them back in the order in which they were recorded.

In other words, the user does not have to perform a troublesome editing work, but simply records each scene suitable for a preset title at a designated position to generate a story-like image with a title screen for each scene. You can enjoy. Moreover, not only the title screen but also the scenes that are usually difficult to shoot are included in the title area to create powerful works.

In the table, the recording date, start / end time, start tape position, and recording channel are written in the memory as a recording reservation so that the tape cassette can be set at a desired position simply by inserting the tape cassette. Recording is possible. In other words, the cueing of the recording position, which was very troublesome in the past, is automatically performed by the deck, and there is no risk of accidentally deleting an important program. Even for those who were not able to set the conventional reserved recording settings, if all the broadcasts of the program to be recorded are stored in the tape cassette by a third party, they can simply insert the tape without performing the cueing operation. You will be able to make a reservation recording by itself.
