Abstract

PROBLEM TO BE SOLVED: To provide a picture recording and reproducing controller which can conduct an appropriate process even in the case where the planned time length of an output is extended while plural animation materials are processed together. SOLUTION: The picture recording and reproducing controller 20 controls pictures in a frame unit and execute reproducing by showing position information for the lines of pictures. Based on the information relative to the length of reproducing time of the pictures to be reproduced and the information of the names of the pictures to be reproduced, plural last or leading frames are continuously pasted after or before a reproduced picture. Thus, a reproducing or an inverse reproducing is conducted against the output materials, in which still or animation pictures are mixed, even though the reproducing time varies with respect to the time length of normal materials. Furthermore, even though a reproducing or an inverse reproducing instruction, which is longer than the length of original materials, is given, the output of a last picture is made continuous. Thus, a sending out accident caused by the operation of sending out and an operational miss, is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image recording / reproducing control device for recording and reproducing images for transmitting a program.

[0002]

2. Description of the Related Art Conventionally, a video tape recorder (VT)
R) and the like, and recording and reproduction of a moving image, and recording and reproduction of a still image by using an electronic image file device and the like have been performed. In the case of a moving image, a time called a time code is recorded on a video tape, whereby a desired scene is searched for. In the case of a still image, a number is attached to the image, and the image is called by designating the number.

[0003] In recent years, devices for quickly locating a desired image by recording the image on a medium different from a tape such as a hard disk (HD) device have been developed and widely used. These are used in non-linear editing and the like because random access can be processed at high speed. For example, an apparatus has been developed in which an image (moving image / still image) is recorded in a non-compressed manner by an HD recording device, and any portion of the recorded image can be reproduced.

[0004] Further, even when an image is recorded on the HD described above, in addition to recording the image itself, which image is used, more specifically, which frame is used and in which order, are recorded. A device that reproduces images in that order has been developed. Specifically, these devices have a feature that the information in the image order has a smaller information amount than the image information, so that even if a plurality of the same materials are recorded, the capacity in the HD hardly increases.

[0005] A frame is a television (T
V) In the NTSC signal format used in Japan and the like, which is the minimum unit of sub-second in a signal, one second is composed of about 30 frames. Naturally, multiple records of the same material here
Although the contents may be exactly the same, the same is true even when a part of the image matches. For example, this means that there are a plurality of one-minute (original) materials that are 15 seconds from the beginning and those that are 20 seconds after. In the case of the above-described recording method other than the recording of the image itself, it means that the image area in the HD has only one minute capacity.

FIG. 10 shows a state in which the image generation is processed by the information of the image order.
The information of the material B131 is pointer information of the images (files) 132, 133, and 134 of each frame. Imagewise, it can be considered that an image file of each frame in the HD is composed of numbers from 000000 to 108000 and an extension (.IMG). 10800
0 indicates that the recording capacity in HD is equivalent to one hour of an image.

In FIG. 10, a material A130 has three frames and a material B131 has two frames.
And the two frames behind the material B131 are common. Therefore, the total number of frames of the material A 130 and the material B 131 is five, but only three frames occupy the HD. Naturally, it is possible to easily realize storing an unrecorded image called BB (black burst) as an existing image in the HD. In the case of BB or the like, a frame image file (name) consisting of a special character string is used instead of the upper 000000 to 108000.

Although the material is used here, for example, a plurality of materials can be arranged to create an image for transmission. In this case, an image for output is used instead of the material in FIG. 10, and a pointer to a frame of each material follows. In addition, images for transmission and recording (hereinafter referred to as Track
(Track). At the time of creation, by pointing the above-mentioned existing BB image, it is possible to easily realize the first unrecorded state.

For example, in the case of FIG. 10, the image file indicating the material A130 is an "A.MOV" file, and its contents are 000000,000001,000002 in order.
Has been accumulated. Similarly, the contents of the “B.MOV” file indicating the material B131 are 000000
1,000002 are stored. 000000. I
MG is the frame image file 132 at the upper right in FIG.
00000. If the IMG is in the middle right frame image file 133, 000002. IMG is the lower right frame image file 134.

When a moving image and a still image are processed using these devices, the still image is output by cueing to the corresponding image. In the case of a moving image, a cue is performed at the beginning of the corresponding image, and then a reproduction instruction is issued. Specifically, when a cue-up instruction (Cue Up) command and a reproduction instruction (Play) command are notified by an RS422 command in a video tape recorder (VTR), an image is output from the image recording apparatus.

[0011]

However, in the conventional image recording / reproducing control apparatus, when a plurality of materials are output, if the reproduction is performed for each material, it takes a long time to call the material. In the case of output by a conventional VTR, this point is often dealt with by combining materials on one tape in advance. In particular, in the case of a commercial (CM) having a short playback time, a plurality of CM materials are put together,
Making tapes with one VTR, or the program itself and CM
Were integrated into a single tape. H
Even in the case of recording in D, even if the image is read immediately before the reproduction of the material, considering the disk access time, etc., if it is known in advance from the call for each material, the material can be combined into a transmission material. desirable.

In the case of broadcasting, the output of the next material is often performed by an operator. For example, in sports broadcasts, CMs are often not pre-scheduled times depending on the progress of the game. Also, the playback time of the material may be longer or shorter than the time of the material itself.

In the case described above and when a plurality of materials are grouped together, if the time is longer than a predetermined time length, processing such as stopping at the last image is required. This is because if the reproduction is continued as it is, a problem such as the reproduction of the next material starts being caused.

[0014] The instruction of the image number from the outside may be performed at the specified time in the above-mentioned playlist, but may be different from the specified time. For example, these are constant because, for example, the time of a commercial becomes a break time of a game in a sports broadcast, or the order of programs is changed in an emergency broadcast. For this reason, a method of describing time uncertainty called “untime” in a time description in a playlist may be employed, or the playback time may be changed by an operation of an operator. Due to this relationship, the start of the image may be performed by the operator, and the image may be transmitted for a time different from the assumed time length. The earlier the reproduction of the next image output is, the shorter the reproduction time of the image is, and the longer the reproduction instruction of the next image output is, the longer the reproduction time of the image is. This means that the HD-related image as the image recording device can be reproduced not only for the time length in the playlist but also for the next reproduction even if the scheduled time is different, and the reproduction time is longer than the scheduled time. In such a case, it is necessary to output an appropriate image (for example, a final image).

Further, an image recording unit including an HD as an image recording device and an image reproduction control device are often separate devices, and the control device processes the above-described Cue Up command or Play command to record an image. Often converted to unit commands. In such a case, if the image playback control device becomes inoperable after issuing the Play command, the playback is continued without forcibly stopping it from the outside, and in some cases, another material may be played back. There can be. For this purpose, it is desirable that an appropriate image is displayed so that a viewer or the like can determine even if the Play state is slightly longer.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and it is an object of the present invention to perform appropriate processing when a plurality of moving picture materials are collectively processed, even if the scheduled output time length is extended. In particular, in the situation where still images and moving images are mixed and prepared as a material for output, even if the playback time differs from the original material time length, image recording and playback will not cause problems in playback It is intended to provide a control device.

[0017]

According to the present invention, there is provided an image recording / reproducing control apparatus which manages images on a frame basis and performs reproduction by designating positional information with respect to an arrangement of images. Based on the information on the length of the playback time of the image to be played and the information on the image name of the image to be played,
A plurality of last frames are continuously pasted after the reproduced image.

An image recording / reproduction control device according to the present invention manages images in frame units and performs reproduction by designating position information with respect to a sequence of images. Based on the information on the length of the playback time and the information on the image name of the image to be played back, a plurality of leading frames are pasted consecutively before the playback image.

According to the image recording / reproducing control device of the present invention, the following operations are performed. In an image recording / playback control device that manages images in frame units and manages the arrangement of images with frame arrangement information, multiple copies of the last frame are generated after the reproduced image, and reproduction is instructed for longer than the material length. In this case, by stopping at the rear margin, the reproduction of a plurality of materials can be processed in accordance with the transmission time.

Further, in an image recording / reproduction control device which manages images in frame units and manages the arrangement of the images based on the arrangement information of the frames, a plurality of copies of the first frame are generated before the reproduced image and are longer than the material length. When the reproduction in the reverse direction is instructed, the reproduction is stopped at the margin at the beginning so that the reproduction in the reverse direction of a plurality of materials can be processed according to the transmission time.

In the above description, the part described as Track is an image file to be processed by the image unit, and the image here includes a cue up instruction (Cue Up) to a time code position like a normal VTR tape. Playback instruction (Pla
The image is processed according to y) or the recording instruction (Rec).

A material part is called Clip 80 for the input Track 82, and a part of the Track can be allocated, or Clip can be allocated to the Track. This Clip can be processed, as it were, as a file on the HD 24, and a name can be specified when generating Track → Clip. Note that the real name is uniquely determined in the HD 24, and if a material having the same name already exists in the HD at the time of generation of Track → Clip, the CPU 2
1 is recognized as an error.

The portion of the clip 80 that looks like a straight line in FIG. 3 indicates the recording of the still image 81. That is, in the case of a still image, Clip may be information of only one frame.

The output T, which is a track for reproduction,
There are two tracks because the outputs 34 and 44 in FIG.
Track1 (83) for output 34, output 44 corresponding to
This is because there is a Track corresponding to the Track 2 (84) for use. In addition, the same Clip is arranged in the two tracks in accordance with the output schedule. For example, FIG.
Is output as the output 34 in FIG. 1, and the material B 88 is output as the output 44 in FIG. When switching from material A85 to material B88,
The source A85, which includes the image 86 from p and the copy 87 of the last frame, is switched to the source B88, which includes an image 89 from Clip and a copy 90 of the last frame. In this case, by controlling a switcher (not shown), the output of the apparatus itself is converted from the image at the output 34 to the output 44.

2 to the remote control device 60 via the interface circuit, and when the material name is specified by an external instruction or the like, the CPU 61 of the remote control device 60 sends Cue U to the top TC.
Thus, p and the like are controlled. Specifically, the CPU 1 notifies the remote controller 60 with the command shown in FIG. 5, and the CPU 61 of the remote controller analyzes the command and creates a table in the memory 62. As a result, the table in the memory 62 is the same as the table in the RAM 2.

A track for reproduction or recording for the image units 30, 40, and 50 is created according to the k generation instruction. Note that these T
The creation of the track is performed when the image unit is not reproducing or recording. That is, when the image unit is reproducing or recording, an error is returned by the CPU 21 in the same manner as the specification of the existing name of Clip described later. In addition, in the case of generating Clip → Track, only the instructed time length is allocated to the Track. That is, it is possible to specify the time length different from the material length here.

When generating a Track → Clip, there is only movement from the recording Track.
Because there is only one, unlike playback, Track1 for output,
There is no identification like Track2 for output.

The CPU 1 uses the command shown in FIG.
When the generation of the rack is completed, the fact is notified to the remote controller 60 via the RS422 interface circuits 4 and 63, and the information corresponding to the recording screen 70 shown in FIG. 2 is notified. The remote control device 60 exchanges information with the APC via the RS422 interface circuit 67, and when the material is ready, the RS422 interface circuit 66

The CPU 1 uses the command shown in FIG.
A track is generated, and an instruction to copy each material corresponding to the recording screen 70 shown in FIG. 2 to the track is issued.
At this time, as described above, two contents having the same Track content are created. When the generation of the reproduction track is completed, the fact is notified to the remote control device 60 via the RS422 interface circuits 4 and 63, and the information corresponding to the transmission screen 75 shown in FIG. Remote control device 60
Transmits and receives information to and from the APC via the RS422 interface circuit 67, and responds to a notification from the APC or a remote control operation by using the RS422 interface circuits 64 and 65.
The image unit 3 of the image recording / reproduction control unit 20 via
A Cue Up, Play command is issued to 0 and 40.

Once a track for playback has been created,
The track information is given a file name indicating that the track is a track, and a file similar to that shown in FIG. 10 is created.
1. The MOV file stores information (usually a number from 000000 to 108000) indicating a frame image in the HD. At the same time, Track1. IM
The value when each frame image is designated by TC (time code) is accumulated in the F file. Normally 0000 at the beginning
00 is a file with a number that increases by one.

The controllers 30 and 40 of the image unit are Tra
The ck frame image number information and time code information are stored in a RAM memory in the controller. RS422
When the position can be designated by the time code via the interface circuits 31 and 41, a corresponding frame image file is obtained based on the table information in the RAM memory, and the CPU
The data is transferred from the HD 24 to the image memories 32 and 42 via the CPU 20. Note that, if this processing is performed each time in the case of reproduction, an image interruption or the like will occur, so that up to the previous image is transferred to the image memories 32 and 42 in advance. For example, Cue from outside
When an Up instruction is received, a time code value (hour, minute, second, frame) in the command is converted into a number indicating a frame image shown in FIG. This calculation is based on hours, minutes,
The number of frames may be calculated from the values of seconds and frames. Based on the values, a number value and a frame image file are read and stored in the image memories 32 and 42. In the case of the variable speed, processing for superimposing or skipping time codes is performed as internal processing.

FIG. 6 is a diagram showing a control command according to the present embodiment. Specifically, RS422 in the image unit
It is notified from the image recording / reproducing control unit or the remote controller by a command to the interface circuit. These commands are the same as control commands in the TVR. In FIG. 6, reference numeral 110 denotes a command 1 (CMD-1), 11
1 is the data count, 112 is the command 2 (CMD-
2) and 113 indicate parameters, and 114 indicates a checksum.

FIG. 7 is a view showing an image call command according to the present embodiment. Specifically, it is a command input via the RS422 interface circuit 66, and is a command for calling an image. In FIG. 7, 120
Is a start of text (STX), 121 is a literal length (LL), 122 is a command (CMD), 12
3 indicates a parameter, 124 indicates a checksum, and 125 indicates end-of-text (EXT).

This command is supplied to the image recording / reproduction control unit 20 via a remote control device 60 operated by an operator. The remote control device 60 is further connected to a program sending computer called APC. That is,
The remote controller 60 determines the command from the APC and the operation itself, and notifies the controller 50 of the image unit of necessary information. Note that the command in FIG. 7 is formally similar to the command in FIG.
D) is different.

For example, when reproducing material A and material B,
When the material name “A” is specified by the OA command, the material name “B” is specified by the NT command, and when the reproduction time of the material B is reached,
A CH command is issued. Thereafter, when reproducing the material C, the material name “C” is specified by the NT command.

When the material name "A" is designated by the OA command, the CPU 61 obtains the head TC of the material A from a table (formally equivalent to FIG. 4) in the memory 62, and obtains the first TC through the interface circuits 64 and 31. Cue shown in FIG.
Issue an Up command.

FIG. 8 is a flowchart showing an operation of generating a track for reproduction according to the present embodiment. In particular,
4 is a flowchart of generation of a track for reproduction by the CPU 1; In this process, a clip is searched in step S4, and when the material of this clip is pasted on the track in step S8, a process is performed in step S9 to copy the final image of the material for one minute. The copy processing of the final image is step S11. After this processing, two identical Tracks are created in relation to the continuous processing of on-air (OA) / next (NT) so that different image units can be processed.

FIG. 9 is a flowchart showing the operation of the remote controller at the time of reproduction according to the present embodiment. Specifically, if the scheduled transmission time length has passed and the material length has passed in step S104, a stop command is issued in step S105. As described above, since the final image has been copied to each track in the track, the final image remains output by issuing the stop command. The final image is copied for one minute, and this processing may be performed within one minute after passing the material length.

In this embodiment, although not particularly specified,
The Track time code assumes a format called a non-drop frame format, and the image signal assumes an NTSC signal format used in Japan and North America. The correspondence to a signal form such as PAL or a form called a drop frame form can be easily implemented by referring to the configuration and operation of the present embodiment described above.

For example, in the case of an NTSC signal, when one second uses a minimum unit of a sub-second of an image called a frame,
29.97 frames (exactly 29.9700261
6), where frames per second are not integers. Therefore, usually, a number from 0 to 29 (that is, 30 frames)
Exists, but the 00 and 01 frames are skipped for each component, and the number of frames is set to 2. However, skipping is not performed for components (0, 10, 20,...) Divisible by 10. This is called a drop frame. Conversely, in a non-drop frame, one second is always 30 frames, so that the number does not skip, but a gap occurs between a long time and a correct time.

In the present embodiment, the repetition of the final image is one minute, but this value is not limited to this, and the value can be easily changed. Moreover, as described above, even if the main repetition is lengthened, the image capacity in the HD does not basically increase.

In the present embodiment, one frame is used for image management.
There is a method called an interlace method in which the image is formed by one image (called a field). However, application of this embodiment to an image of the interlace method can be easily realized by referring to the above-described configuration and operation.

In the present embodiment, the still image is identified with the material length = 0. Naturally, the same processing can be performed even if the effect of a still image is represented by a specific symbol, or whether or not a part of the material name can be used to determine whether the image is a still image.

In the above-described embodiment, as shown in FIG. 3, the copy of the last frame of the material A is performed in order to control the reproduction within the image range even if a reproduction instruction longer than the material length is issued. 87, the final frame is copied 90 for the material B, and the final image is copied at the rear end in the reproduction direction. In the case of normal forward reproduction, the above-described embodiment can cope with this.
Conversely, Clip A for material A shown in FIG.
86 from Image, Image 8 from Clip for Material B
Prior to step 9, the first frame is copied for material A and the first frame is copied for material B at the beginning in the playback direction so that the first frame is copied in the playback direction. May be controlled so as to be reproduced.

In the case of reproduction in the reverse direction, the following operation is performed in the flowchart of FIG. 8 showing the operation of generating a reproduction track according to the present embodiment. Specifically, in the flowchart of the generation of the track for reproduction by the CPU 1, in this processing, the Clip is determined in step S4.
Is searched, and in step S8, the material of this Clip is
When pasting to the ck, in step S9, processing is performed so that the leading image of the material is copied for one minute. The process of copying the last leading image is step S11. After this processing,
Two identical tracks are created in relation to the continuous processing of on-air (OA) / next (NT) so that different image units can be processed.

In the above-described embodiment, the determination as to whether or not the image is within the image range is made by processing the information of the head position and the material length. However, the present invention is not limited to this. Alternatively, a process of calculating the reproduction position from information on the start position and the end position may be employed.

In the case of the reproduction in the reverse direction, the following operation is performed in the flowchart of FIG. 9 showing the operation of the remote control device at the time of reproduction according to the present embodiment. Specifically, instead of steps S101 to S102, the image recording / reproduction control unit 20 calculates the range of the reproduction position from the information on the start position and the end position, and proceeds to step S104.
In step S105, a stop command is issued if the playback position is beyond the range of the playback position. As already mentioned, Trac
Since the leading image is copied to each of the materials k, the issuing of the stop command keeps the leading image output. Note that the leading image is copied for one minute, and this processing may be performed within one minute after passing the playback position that is the material length.

The image recording / reproducing control device of the present embodiment
