Description

  The present invention relates to dubbing to a VTR (Video Tape Recorder) in a non-linear bank system.

The conventional non-linear bank system does not have a dubbing function of VTR (Video Tape Recorder), and when dubbing a master tape or the like, only VTRs are connected one by one and executed. The case of dubbing a master tape or the like is, for example, when dubbing from a VTR to a VTR, when obtaining a backup copy with the customer's consent when returning an original tape, or when creating a test tape, etc. is there. Further, as a dubbing from the server to the VTR, the material produced in-house is registered in the bank system, and then the tape is lost, and when this material is used in a program thereafter, the material may be copied from the server to the tape.

FIG. 1 is a diagram showing the configuration of a conventional non-linear bank system with reference to FIG. As shown in FIG. 1, HD (High Definition) material is reproduced by VTR (Video Tape Recorder) 11 to 12, and SD (Standard Definition) material is VTR (Video Tape Recorder) 13. Both are recorded in the server 4 via the matrix switcher 2 by being reproduced at .about.14.
Conventionally, when performing one-to-one dubbing between VTRs, there is only a dubbing method with a low degree of freedom that can simply dubb a material and cannot edit angle of view conversion, audio mapping, and the like. In addition, before and after the dubbing operation, it is necessary to change the cable connection between the reproduction-side VTR and the recording-side VTR.
In addition, as in Patent Document 1, dubbing and the like can be executed by connecting video recording / playback apparatuses when editing video, but there is no such thing as a system for sending a program such as a non-linear bank system. It was.
An object of the present invention is to solve the above problems and provide a non-linear bank system that can perform dubbing to an arbitrary VTR without the need to change the connection such as cable reconnection.

In order to achieve the above object, the nonlinear bank system of the present invention includes a plurality of HD VTRs and SD VTRs, and a video medium on which HD format video is recorded or a video medium on which SD format video is recorded. In a non-linear bank system that records on a server via a matrix switcher that switches input / output to / from the audio / video converter and server, and that is OA (On Air) from the server, it further includes a time code switcher. Dubbing is enabled by switching the time code switcher by operating the terminal.
That is, the non-linear bank system of the present invention includes a video recording / reproducing device, a video / audio converter, a matrix switcher, a server, and a bank registration controller for switching the matrix to record and preview a material. The bank registration controller controls the time code switcher and the matrix switcher, and dubbes the material onto a recording medium using an arbitrary video recording / reproducing device.

  According to the present invention, the dubbing function is newly provided in the non-linear bank system, so that it is possible to perform the dubbing operation without changing the cable connection for all the VTRs connected to the system.

Hereinafter, an embodiment of the present invention will be described with reference to FIG. FIG. 2 is a diagram showing a configuration of a non-linear bank system according to an embodiment of the present invention. 11 and 12 are HD video recording / reproducing devices (HDVTR), 13 and 14 are SD video recording / reproducing devices (SDVTR), 2 is a matrix switcher, 3 is a video / audio converter, 4 is a server, and 5 is a bank registration. A controller 61 is a registration / preview terminal A, 62 is a registration / preview terminal B, and 7 is a TC (Time Code) switcher. In addition, a broken line is a HD (high-definition) system signal line, a two-dot chain line is an SD system signal line, a solid line is a control system signal line, and a one-dot chain line is a TC system signal line. The video recording / reproducing devices 11 and 12 for HD and the video recording / reproducing devices 13 and 14 for SD are, for example, VTRs (Video Tape Recorders).
The bank registration controller 5 controls devices to be controlled (for example, the VTRs 11 to 14, the server 4, the video / audio conversion converter 3 and the like) in order to register materials in the bank system. It is a computer.

The non-linear bank system shown in FIG. 2 is provided with a TC switcher 7 in addition to the conventional configuration shown in FIG. It is used for recording. Also, one of the HDVTR 11 or 12 and the SDVTR 13 or 14 is used for playback, and the other is used for recording.
In FIG. 2, the HD material and the SD material are usually input to the matrix switcher 2 in the non-linear bank system and recorded in the server 4. Depending on the specifications, when recording, up-converter, down-converter, VBI (Vertical Blanking Interval) / ANC (Active Noise Control) conversion, and voice processor are used to perform angle-of-view conversion and voice mapping.
In addition, regarding the preview of the recorded material, the system is connected from the decoder of the server 4 to the preview table (registration / preview terminal A61, registration / preview terminal B62) through the matrix switcher 2 via the PV system.
In the present invention, the material recording / preview system mainly including the matrix switcher in the nonlinear bank system as shown in FIG. 2 is used, and the dubbing process is added to enable the dubbing of the VTR as the nonlinear bank system.

The operation of one embodiment of the dubbing process of the present invention will be described with reference to FIGS. FIG. 3 is a block diagram illustrating components necessary for dubbing in the non-linear bank system. FIG. 4 is a flowchart for explaining the dubbing processing operation.
3, the matrix switcher (see the matrix switcher 2 in FIG. 2) and the TC switcher (see the TC switcher 7 in FIG. 2) are omitted, but the matrix switcher or TC switcher is controlled according to the control of the bank registration controller 5. At least one of the above operates and a signal is transmitted between the components.

In the bank system shown in FIG. 3, first, in the playback side VTR setting step 401 shown in FIG. 4, the user attaches a playback medium to the video recording / playback apparatus (for example, HDVTR 11 or SDVTR 13 in FIG. 4).
Next, similarly, in the recording side VTR setting step 402 in FIG. 4, the user attaches a recording medium to the video recording / reproducing apparatus (for example, HDVTR 12 or SDVTR 14 in FIG. 4).
Note that the processing order of steps 401 and 402 may be reversed.

Next, in the dubbing operation start step 403, the user operates any of the registration / preview terminal A61, the registration / preview terminal B62, or the registration / preview terminal C63 to start the dubbing operation.
Next, the bank registration controller 5 receives a dubbing operation start signal, and checks the status of each component (each component device) in a reproduction VTR status check step 404. Hereinafter, unless otherwise specified, it is assumed that the processing operation is executed by the bank registration controller 5.
If the status of the playback VTR (for example, HDVTR11 or SDVTR13) is in a reproducible state, the process proceeds to a playback start cueing step 406. If not, the playback VTR status check step 404 is started again. .

In a reproduction start cueing step 406, the reproduction VTR is controlled to enter a standby state where reproduction can be started. That is, if the medium to be reproduced is a magnetic tape or the like, the apparatus stands by with the reproducing head positioned at the beginning of reproduction. If the medium to be reproduced is a non-linear medium that can be reproduced, the apparatus waits so that the reproduction can be started at the start address.
Next, in the recording side VTR status check step 407, if the status of the recording VTR (for example, HDVTR 12 or SDVTR 14) is in a recordable state, the process proceeds to the TC switcher status check step 408. The VTR status check step 407 is started again from the beginning.

In the TC switcher status check step 408, the status of the TC switcher 7 is checked to check whether or not the connection of the server 4, the playback VTR, and the recording VTR is in an appropriate state. If it is in an appropriate state, it proceeds to a matrix (MTX) switcher status check step 409, and if it is in an inappropriate state, the MTX switcher status check step 409 is repeated.
In MTX switcher status check step 409, the server 4, playback VTR, recording VTR, video / audio converter 3 (original dubbing audio processor 31, D / C (Down Convert) audio processor 32), which is a reentry system, The connection state of the original dubbing audio processor 33 and the U / C (Up Covert) / VBI (Vertical Blanking Interval) / ANC (Active Noise Control) audio processor 34) is confirmed. That is, the bank system is used for other users (or other registration / preview terminals) and other work, and performs reproduction and recording, and the audio / video converter 3 performs desired conversion on the reproduced video and performs recording. Check the status of the reentry system to see if switching is possible. If it is possible, the process proceeds to the video / audio conversion processing control step 410. If it is impossible, the MTX switcher status check step 409 is repeated. The reentry system means a system for returning video from the matrix switcher 2 to the matrix switcher 2 again through a device that performs video / audio conversion processing, and is not necessarily limited to the original dubbing audio processor 31 and the D / C audio processor. 32, not only the original dubbing audio processor 33 and the U / C audio processor 34.

In the audio / video conversion processing control step 410, angle of view conversion, audio conversion, VBI / ANC conversion, time code conversion, and the like are executed.
In the MTX switcher I / O line control step 411, the MTX switcher 2 is controlled to switch the input line and the output line to perform a desired connection.
In the TC switcher I / O line control step 412, the TC switcher 7 is controlled to switch the input line and the output line to perform a desired connection.
In the reproduction VTR control step 413, reproduction of a reproduction VTR (for example, HDVTR11 or SDVTR13) is started.
In addition, the material that has been reproduced at the start of step 413 and has undergone predetermined conversion starts recording in a recording VTR (for example, HDVTR 12 or SDVTR 14) in recording control step 414.
In the recording VTRSTOP control step 415, when the recording of the material is completed, the recording of the recording VTR is stopped and the recording of the material is ended.
Next, in a reproduction VTR control step 416, the reproduction of the reproduction VTR is stopped and the reproduction of the material is ended.
Thus, dubbing is finished.

In the above embodiment, the user performs dubbing control on the playback and recording side VTRs via the registration controller 5 from the registration / preview terminals A61, B62, C63, and the like.
When the HD material is played back and converted to SD material for recording, down conversion (D / C) is performed, and when the SD material is played back and converted to HD material for recording, up conversion (U / C) is performed. As described above, the angle of view conversion, the sound conversion, and the VBI / ANC conversion are selected, and the dubbing operation is performed using the conversion device and the material recording system in the non-linear bank system.
In addition, it is possible to change the pixel size, change the aspect ratio, and change the video format (from MPEG4 format to H.264 format).
Further, by using the TC (time code) switcher 7, not only the material VITC (vertical interval time code) but also LTC (longitudinal time code) can be dubbed. Furthermore, by using the preview system from the server 4, the recorded material can be dubbed to the VTR.

According to the above-described embodiment, the dubbing function is provided as the non-linear bank system so that all VTRs connected in the system can be automatically dubbed without changing the connection such as cable reconnection. Can do. In addition, a dubbing function with a high degree of freedom such as angle-of-view conversion, audio conversion, VBI / ANC conversion, and the like is made possible by using a video / audio conversion device that is usually included in a non-linear system.
Furthermore, by using the material preview system, VTR can be dubbed even for materials already recorded on the server.
