Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an editing system used to control dubbing of content recorded on a magnetic medium such as a VTR tape.

(Prior art) Conventionally, when dubbing a recorded VTR tape using two VTRs, while watching the playback screen, the playback and recording VTRs are checked for the playback and recording conditions in the areas necessary for editing. While manual operation is performed to ensure that
The playback VTR was controlled to fast-forward while the video was paused.

(Problem to be solved by the invention) However, in the conventional editing system, in order to control dubbing as described above, it was necessary to operate two V'rRs at the same time while constantly monitoring the playback screen. .

(Means for Solving the Problems) The recorded content distribution system for magnetic media of the present invention includes a reproducing device that reproduces recorded content on a magnetic medium, and a reproducing device that edits and records desired content from the recorded content. A system consisting of a recording device and configured so that the operation of the recording device can be controlled from a playback device, wherein an editing code is placed immediately before and at the end of an unnecessary portion of the recorded content that should be deleted during editing. a recording means for recording; a means for reproducing the editing code to recognize the position of the unnecessary portion; a means for controlling reproduction by skipping over the position-recognized unnecessary portion; and means for controlling the apparatus to a recording standby state.

(Operation) First, an editing code is recorded so that unnecessary parts to be deleted can be searched during editing. For example, this editing code is placed just before the unnecessary part (this is called the IN signal) and at the end (
This is called the OUT signal. ). Then, the dubbing state is established in which the playback device can control the operation of the recording device.

When the reproducing device starts reproducing the recorded content, the recording device is put into a recording state. When the playback device detects the IN signal, it puts the recording device into a recording standby state and puts the playback device into a fast forward mode. On the other hand, when the reproducing device detects the OUT signal, the reproducing device is returned to the reproducing state and the recording device is returned to the recording state. Thereafter, the above control is automatically performed every time an IN signal or an OUT signal is detected.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIGS. 1 and 2 show an embodiment in which a magnetic medium recorded content editing system according to the present invention is configured with two VTRs, a reproducing VTRI and a recording VTR 2. FIG.

FIG. 1 shows an example of the connection between the playback VTR 1 and the recording VTR 2.
They are connected by three types of signal lines: an audio signal line 4 and an operation control line 5. The signal transmission direction in these signal lines is from the playback VTR1 to the recording VTR2.
Address 5earch System) Control part A
is its control body.

FIG. 2 is a block diagram showing a case in which the VASS control unit shown in FIG. 1 is configured with the control function block, and the operation control line 5 is configured with a wireless path using an optical remote control signal.

In the playback VTR, 7 is a VTR cassette, 8 is a video head, ram, 9 is a control head, 1O
indicates a videotape.

The control head 9 has a VA consisting of a vASS code.
The SS signal is recorded and played back on the control track of the video tape 10, and in this example, the editing code created using this VASS code is also recorded and played back. Reference numeral 11 denotes a VASS signal write/continue control section, and this write/continue control section 11 cooperates with the system control section 12 of the playback VTR for operations of cue operation switches, dubbing operation switches, etc. (not shown). An optical remote control signal for controlling the operation of the recording VTR 2 is sent to the remote control light receiving section 14 of the recording VTR 2 via the remote control output section 13.

The editing codes in this example include an editing end code (hereinafter referred to as the END code) that is written just before the end of the part that should be left during dubbing editing (hereinafter referred to as the actual recording part 15), and an editing end code (hereinafter referred to as END code) to be deleted during dubbing editing. A cut start code (hereinafter referred to as IN code) and a cut end code (hereinafter referred to as OUT code) are written immediately before and immediately before the end of the unnecessary part (hereinafter referred to as CM recording part 16) that should be cut (hereinafter referred to as CM recording part 16). It consists of three codes. and,
According to the VASS regulations, in this example as well, each code is written three times in succession for IN signal 17a, OUT signal 17b, and END signal.
It is called signal 17c. For example, the IN code is r990
0J, the IN signal 17a actually recorded on the control track is [9900, 9900, 9900
It becomes J. In addition, the IN, OU, and TSEND signals 17
The writing start position of a-17c starts from the point in time when the recording length required to write each signal is rewound by the time converted into playback time. As a result, each signal 17a
The end of the line 17c is slightly in front of the start end 16a of the actual recording portion 15 and the CM recording portion 16.

Next, the procedure for writing the edit code will be explained with reference to FIG.

FIG. 3 is a tape schematic diagram illustrating the editing code writing operation. When the reproducing VTR 1 is in the reproducing state, when an editing code write command is outputted by an operation switch (not shown), the write/continue play control section 11 is commanded to rewind. In this example, the IN signal 17a
The recording length of 2.7 seconds is converted into a playback time, and the stabilization time required to transition from rewind mode to playback mode (3
command to rewind the tape by 6 seconds, taking into account the length of the tape (seconds). Thereafter, when the reproduction state becomes stable, a VASS code corresponding to the edit code is written after a period of 3 seconds has elapsed. As a result, the IN signal 17a is recorded to a position slightly in front of the starting end 1'6a of the CM recording portion 16.

The procedure for writing the edit code described above is as follows:
a, OUT signal 17b, and END signal 17c, resulting in the tape state shown in FIG. In Fig. 4, the continuous actual recording portion 15 is
, production (2), and production (3).

When the editing code is written as described above, automatic dubbing editing becomes possible. When automatic dubbing editing is instructed, the write/continue control section 11 first outputs a recording pause command from the remote control output section 13 to the recording VTR 2.

Upon receiving this command, the system control unit (not shown) of the recording VTR 2 maintains the recording VTR 2 in a recording pause state. Next, the write/continue output control section 11 outputs a playback command to the system control section 12, and puts the playback VTR 1 into a playback state. After that, this write/continue output control section 1
1 is a recording VTR 2 for the remote control output section 13.
command to output the pause release command. Upon receiving this command, the system control section of the recording VTR 2 controls switching from the recording pause state to the recording state.

In this way, after the reproduction VTR 1 is in the reproduction state and the recording VTR 2 is in the recording state, the control head 9 reads out the VASS signal. When the write/continuation control section 11 detects the IN signal 17a in the VASS signal, it first puts the recording VTR 2 in a recording pause state and then fast-forwards the reproduction VTR 1.

On the other hand, when the OUT signal 17b is detected, the playback VTR 1
After putting the video recorder 2 into a playback state, the system controller 12 receives information indicating that the video recording VTR 2 is being played back and instructs the recording VTR 2 to release the pause.

After repeating the detection operation of the IN signal 17a and the OUT signal 17b, when the END signal 17c is finally detected, the recording VTR 2 is first stopped, and then the playback VTR 2 is stopped.
Stop R1 and turn on the power to both VTRs 1 and 2.
FF. Thus, the tape that has undergone the above-described editing procedure has continuous actual recorded portions 15 as shown in FIG. Note that during automatic dubbing editing, the writing/continuation control unit 11 first searches for the IN signal 17a unless the END signal 17c is detected, and when cutting the CM recording portion 16 by the IN signal 17a, searches for the OUT signal 17b. A search operation is performed, thereby preventing malfunctions even if the IN signal 17a or the OUT signal 17b is written continuously. Further, although this example is applied to a VTR, it can also be applied to devices using other magnetic media, audio equipment, etc.

(Effects of the Invention) As described above, according to the present invention, it is possible to perform automatic dubbing editing in which unnecessary recorded portions are cut and necessary recorded portions are continued without any troublesome operations.
