Description

The present invention relates to a program transmission server and a program re-recording method for recording on-air program content at a broadcasting station.

Broadcasting program transmission is managed by an APC (automatic program transmission device). In other words, event information such as selection switching of devices related to transmission of program contents created from a program timetable distributed from a data server (hereinafter abbreviated as DS) of the center station includes SCP (Sche).
(dule control processor), and the SCP refers to each data of the event information, and the program content is transmitted at a predetermined time.

While OA (on-air) is in progress, predetermined devices and contents such as a program transmission server and other material transmission devices are selected and switched by SCP control according to the program timetable and event information.

As the OA control of the current broadcasting station is managed by event information as described above and the program is controlled and transmitted by the SCP, when changing the content of the recorded video, the event data is monitored by the control console or material. Change from control input means such as management system. In principle, for example, processing such as changing the content name of the program to be changed and the name of the material sending device that sends the content is required, and the data related to the event information of the upper DS or SCP is changed. .

Thus, in news, news programs, etc., for example, it may be necessary to urgently replace the content recorded in the video server with a new one recorded at the news source. Traditionally,
As for such replacement, a method is employed in which the content recorded in the video server is deleted and the content recorded again with the same content name (ID) is transmitted from the video server.

However, if it becomes necessary to perform OA in the middle of re-recording, since there is no content or it is not complete, broadcast suspension will occur, so it is not easy to replace content urgently, and replacement processing The operator's procedural error was easy to occur.

On the other hand, as a method for quickly replacing content, a new switching destination device in the SCP is allocated without changing the higher-level device setting data (for example, Patent Document 1), and the spare program transmission server is assigned. There is also a method of switching and recording replacement contents in advance. However, even in this case, an urgent replacement recording cannot be made in time.

In addition, replacement may be directed to re-recording from the material management system instead of management by the SCP, and an on-air command is received during re-recording because it is not urgent because it does not correspond to the program timetable. Sometimes it is done.
JP 2007-13495 (page 12, FIG. 1)

To replace and re-record the content stored in the video server in the past,
Since there is a need for extra time to re-record after deleting the recorded content, it is difficult to urgently replace content that is imminent on air, and if an on-air command is received during re-recording, There was a problem that a broadcast accident occurred.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a program transmission server and a program re-recording method that prevent accidents even when emergency replacement of contents is performed.

Re-recording that replaces the ID with the original ID assigned to the data of the first material that has already been stored and stored, and deletes the data of the first material The data of the re-recorded material replaced with the original ID by the on-air command input via the command input means is read out from the storage medium and sent out, and before the write recording is completed, And a control management means for performing control to read out and send out the data of the first material to which the original ID, which has already been accumulated, is assigned, when the on-air command is received. And

The program re-recording method of the program transmission server of the present invention includes a storage medium, command input means,
Control management means for recording program material data to be recorded on a storage medium by a recording command, and reading program material data stored and stored in the storage medium by an on-air command input from an automatic program transmission facility In the program re-recording method of the program sending server for sending to the transmitter, the control management means to which the recording command is inputted via the command input means, the inputted recording command is already stored in the storage medium. In the case of the re-recording command of the accumulated material, a temporary ID is given to the data of the input program material and written and recorded in the storage medium. Perform re-recording to replace the ID with the original ID assigned to the data of the first material that has already been stored and stored, via the command input means When the on-air command is input, the original I
When the re-recorded material data replaced by D is read out from the storage medium and sent out, and the on-air command is received before the completion of the writing and recording, the original ID that has already been accumulated is given.

According to the present invention, it is possible to provide a program transmission server and a program re-recording method that prevent accidents even when content is urgently replaced.

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

FIG. 1 is a system diagram showing an automatic program transmission system using a program transmission server according to an embodiment of the present invention.
In FIG. 1, an automatic program transmission system for transmitting program material (contents) to a transmitter is a program transmission server BS, SCP (Sc) composed of a video server 1 and a control management device 4.

The control network 5 includes a video server 1, SCP 2, a supervisory control console 3, a control management device 4,
The control network 5, the switcher 6, the DS 7, the playback device 1a, and the material sending device 1b are connected to transmit selection information of the material sending device, data specifying the material, and timing information such as on-air time. ing. Data relating to the program timetable is supplied from DS1 to SCP2 via this control network 5 or by a storage medium or the like.

The SCP 2, the supervisory control console 3, the control network 5, the switcher 6, etc., which perform processing for automatically sending a program according to the program timetable from the DS 7, are collectively referred to as APC (automatic program sending equipment) 9.
Called.

The SCP 2 selects and drives the various devices related to the transmission control of the program material based on the program timetable supplied from the DS 7 that performs overall management of the program transmission schedule,
Event information for setting content is generated, and an event control command, an on-air command, and the like are transmitted to various devices via the control network 5.

The monitoring control console 3 is a control console operated by an operator called a touch panel, for example, and communicates with each device via the control network 5 to input a command for setting a new event in the SCP 2. It is also a device that receives and monitors responses to commands sent from the SCP and monitor information. Also, it functions as an input means for manually sending an event command or an on-air command instead of the SCP2.

The control management device 4 is connected to the control network 5 and the video server 1 and is a control management device used for setting and monitoring the material stored and stored in the video server 1 and the data to be transmitted and managed, and may be an information terminal such as a PC. . The program transmission server BS is an apparatus that receives event commands for the video server 1 transmitted from the SCP 2 via the control network 5 and controls and manages the storage (storage) of material (contents) and the transmission operation in the video server 1.

The switcher 6 is based on a control signal from the SCP 2, such as a network 8 as an event, a video server (not shown) used for the program transmission server BS, a playback device 1 a such as a VTR, a studio camera, etc. A device for selecting and switching a plurality of devices that input and output various program signals such as the material sending device 1n and the like. A network 8 is a network that transmits program material signals input and output by the above-described devices. is there.

The program delivery server BS is an SCP that the control management device 4 receives via the control network 5.
The material (content) stored and stored in the video server 1 in accordance with the on-air command from 2
Is sent to the transmitter via the switcher 6 and the network 8, and similarly receives a recording command from the SCP 2, the monitoring control console 3, etc., and inputs the material (contents) input via the switcher 6 and the network 8. ) Is stored and stored.

FIG. 2 is a functional block diagram for explaining the operation of the program transmission server BS.
FIG. 2 shows an example of the configuration of the program transmission server BS. Here, the video server 1 and the control management device 4 are combined. The video server 1 that accumulates and stores materials (contents) includes a storage medium 10, a CPU 11, and a video IF 12 that are connected to each other via an internal bus or the like.
A communication I / F 13 and an I / O (input / output) I / F 14.

The control management device 4 that controls the video server 1 includes a memory 40, a CPU 41, a communication I / O.
F42, input / output unit 43, I / OI / F44, and internal clock 47 are provided.

The communication I / Fs 13 and 42 are connected to the control network 5, and various control information such as event data is input / output between the SCP 2 and the monitoring control console 3. The I / O I / Fs 14 and 44 connect between the CPU 11 and the CPU 41 that control the internal operation of each device, for example, a bus that performs high-speed data transfer that performs control such as writing and reading of the storage medium 40. Or an interface of signal lines. Dedicated data bus between CPUs, USB, SCSI
An input / output interface such as I is used.

The input / output unit 43 of the control management device 4 is input / output means such as a keyboard and a display of the information terminal. The internal clock 47 is referred to by the CPU 41 in order to control the timing of operation corresponding to the event command from the SCP 2. Further, the memory 40 stores an operation of the control management device 40 and a sequence control program for controlling the video server 1.

If necessary, the video server 1 is a memory that functions as a work memory in which a content list 46 is stored as a material to be stored and stored, and a content management table necessary for managing the transmission of the material and the like.

The storage medium 10 is a high-capacity storage medium such as a semiconductor or a magnetic disk that can be written and read at a high speed corresponding to an operation command from the control management device 4. The video I / F 12 performs an interface for inputting / outputting material data stored and stored in the storage medium 10 to / from the network 8, and if necessary, data written to the storage device and the network 8 It also has a function of performing coding conversion between data input and output between the two.

As a basic operation, an event command transmitted to the program transmission server BS from the SCP 2, the monitoring control console or the like via the control network 5 is once input by the control management device 4 41. Then, the CPU 41 issues an operation command for the video server 1 to the I / O I / F 14,
4 to the CPU 11.

The internal operation of the video server 1 is monitored and controlled by the CPU 11. For example, sequence control for ID management, writing, and reading of materials related to recording processing described later is performed by the CPU.
The CPU 11 performs overall management, and the CPU 11 performs start / stop of the storage medium, writing / reading of the stored data, and input / output control with the network 8 according to the sequence control.

Here, for the sake of convenience, the operation of the program transmission server has been described with the above configuration, but the configuration form of the video server 1 and the control management device 4 is not limited to this. For example, the functions of the video server 1 are accommodated in the control management apparatus 1 and integrated, and a portion corresponding to the memory 40 of the control management apparatus 1 is replaced with a large-capacity storage medium of the storage medium 10 and the video IF 12 May be provided in the control management device 1.

FIG. 3 is a flowchart showing a processing procedure in which the control management device 4 controls the video server 1.
Hereinafter, the operation of the program transmission server BS will be described with reference to FIGS.

The CPU 41 receives the re-recording command “STR: 123ABC” transmitted from the monitoring control console 3 to the program transmission server BS via the control network 5 via the communication I / F 42 (step s1 in FIG. 3). The CPU 41 interprets it as a recording command for instructing re-recording of the material (content) whose “STR” is the material ID “123ABC” (Yes in step s2).

Then, the content of the video signal input via the switcher 6 is assigned the temporary ID “123AB.
A command to be written and recorded with “CR”, for example, “W: 123ABC-R” is sent to the CPU 11 (step s-4), and a response to the write recording is awaited.

From the supervisory console 3, the switcher 6, video server 1 and VT are synchronized with the re-recording command.
For example, a command to send data of the recorded material “123ABC” from the VTR 1 b to the R 1 a and input it to the video server 1 via the control network 5,
It is transmitted to the switcher 6 and the VTR 1b. Then, the data of the material whose ID is “123ABC” is input from the VTR 1 a to the video server 1 via the switcher 6.

Needless to say, the present invention is also applied when a re-recording command is input from the input / output unit 43 of the control management device 4 instead of the monitoring control console.

Receiving the write / record command, the CPU 11 names and records the temporary ID “123ABC-R” in the storage medium 40 to the material data input from the VTR 1a. And C
The PU 11 transmits a completion response to the CPU 41 when the writing / recording is completed.

On the other hand, the CPU 41 monitors an on-air command from the control network 5 while waiting for a response to the write recording. If the CPU 41 receives a response from the write / record completion response CPU 11 before receiving the on-air command (No in step s5), the temporary ID
In step s6, a rename command for replacing the ID of the material data written and recorded in step 1 with the original 123ABC is transmitted. Then, the previously recorded material data is deleted from the storage medium 10, or is replaced with a temporary ID, or a revision command that is renamed and stored in another ID is transmitted to the CPU 11 (step s7).

In other words, instead of assigning “123ABC-R” to the material data already stored in the storage medium, the name may be changed to a third ID, for example, “123ABC-R2”.

FIG. 4 is an example of a content list 45 showing materials written and accumulated in the storage medium 40.
FIG. 4A shows the content list 45 in a state waiting for an on-air command before the program transmission server BS receives the re-recording command or after the completion of the re-recording. FIG. 4 (b)
This is the content list 45 of the material being re-recorded (steps s4 and 5).
“3ABC” indicates a material that has already been stored, and “123ABC-R” indicates a file of data that is being written and stored for re-recording.

When the writing / recording is completed, the CPU 41 replaces (replaces) the original ID assigned to the data of the already accumulated material and the temporary ID assigned to the data for which the writing / recording is completed. (Step s6).

If the material data already recorded is to be deleted, “123ABC-
The material data to which the temporary ID “R” is assigned is erased from the storage medium and deleted from the content list, and the state shown in FIG. When the name is changed, the state of FIG. 4B is maintained, and the data of the old material is also left in the storage medium 40.

In the case of deletion, there is an effect that a sufficient storage capacity of the storage medium 40 can be secured. Renaming is a method suitable when there is sufficient capacity and it is not necessary to secure a margin. By accumulating the old material and the new material, there is an effect that the old material can be used for backup, and a plurality of content candidates can be prepared to wait for an on-air command. The operator sets in advance from the input / output unit 43 whether to delete or rename.

As another method, the CPU 11 obtains the monitor data of the accumulated data amount of the storage medium 40 as C
Although the data is transmitted to the PU 41, the CPU 41 monitors the monitor data, and determines the sending condition of the revised command to delete when the free space of the storage medium 40 is not 60% or more of the total capacity, for example. It may be left.

After that, when it is scheduled to broadcast a normal program, the on-air command to send “123ABC” is SC
It is transmitted from P2 to the program transmission server BS. In accordance with the received on-air command, the CPU 41 reads “123ABC” from the storage medium 40 and transmits a send command to be output to the network 8 via the switcher 6 to the CPU 11 (step s8).

The CPU 11 that has received the send command reads “123ABC” from the storage medium 40 and outputs it to the switcher 6 via the video I / F. On the transmitter side, the “123ABC” material is input via the network 8 and broadcasted.

The on-air command is normally sent from the SCP 2, but during re-recording in a hurry, if the transmission timing comes before the write recording is completed, or the monitoring control console 3 urgently There is a case where the transmission of the material (here, the material ID is “123ABC”) is instructed, that is, an on-air command is received (step s5 is Yes).

In this case, the CPU 41 reads “12” from the storage medium 40 in accordance with the received on-air command.
“3ABC” material data is read out and sent to the CPU 11 via the switcher 6 and sent to the network 8 (step s8). The material before re-recording that has been stored even during re-recording is read out from the storage medium 40 and sent to the transmitter via the switcher 6 and the network 8. Although there is a drawback that the content of the material remains old, it is possible to send a program that prevents the occurrence of an accident such as no content or being in a state of being cut off during broadcasting.

In addition, when the material ID “123ABC” is recorded for the first time instead of re-recording, the recording command is “ST: 123ABC” without R indicating re-recording, for example. C
The PU 41 determines that the recording is the first recording by reading the “ST”. Then, a command for writing and recording the ID “123ABC” as it is, for example, “W:
123ABC "is transmitted to the CPU 11, and the material output from the VTR 1a is the ID" 123A ".
BC ”is written and recorded in the storage medium 40 of the video server 1 (step s3), and a new material ID name 123ABC is also added to the content list 46.

FIG. 5 is a flowchart showing a procedure of re-recording processing in a modified example of re-recording, and FIG. 6 is an example of a content management table 45 referred to by the CPU 41 of the control management unit 4 in the modified example.
The content management table 45 is input from the input / output unit 43 in advance, or the communication I / O
The ID of the material data stored in the storage medium of the video server 1 is input together with the scheduled broadcast time via F42, and the CPU 41 associates the scheduled broadcast time with the ID to generate a table for content management. It is written and stored in the memory 40.

In the modified example, there is no distinction between the recording command and the normal recording command.
Further, a sequence control program of the CPU 41 is set in the memory 40 so as to be able to cope with the case where the content recorded at the scheduled time is sent to the transmitter instead of the on-air command.

In FIG. 5, when the same processing as in FIG. 2 is performed, the same step number as in FIG. 2 is assigned, and another step number is assigned for the step of performing the added or changed processing.

The CPU 41 of the control management device 41 collects data files stored and stored in the storage medium 40 at predetermined regular intervals via the CPU 11 and writes and stores them in the memory 40 as a content list 46.

Similarly, the information of the program timetable input via the control network 5 is monitored,
The transmission timing (time) of the material (content) transmitted from the program transmission server is extracted, and is written and stored in the memory 40 as the content management table 45 (step s0 in FIG. 5).

Now, assume that “ST: 123ABC” is received as a recording command (step s1).
. The CPU 41 collates with the content list 46 (step s1-1), and checks whether there is a material with ID “123ABC” in the content list. And if there is (step s2
-1 is Yes), it is determined to be re-recording, and thereafter, "123AB" as in the re-recording in FIG.
The write recording command “CR” is transmitted to the CPU 11 (step s4).

During writing / recording, the CPU 41 compares the content management table 45 with the internal clock 47, compares the difference with the program transmission timing, and when it becomes a predetermined time difference, in other words, when it is on-air timing (step) If s5-1 is Yes), control is performed to send material data whose ID is “123ABC” already stored in the storage medium 40 (step s8). In FIG. 6, for example, when time 00:19:59 has passed and the remaining one second has been cut off, “123ABC”
Corresponds to the case of sending material data with an ID of "".

If the writing / recording is completed before the predetermined time difference is reached (No in step s5-1), the ID is replaced, the material is deleted, the name is changed, etc. as in FIG. 2 (steps s6 and s7).

In other words, the CPU 41 refers to the content management table 45, compares the difference with the program transmission timing, and performs control related to the material transmission similar to the case where the on-air command is received when the predetermined time difference is reached.

On the other hand, if the ID of the program material set in the recording command is not described in the content list (No in step s2-1), the CPU 41 directly adds the ID “1” to the input program material.
23ABC "is assigned and recorded in the storage medium 40 (step s3).

Note that the same operation as step s5 in FIG. 2 is also performed when the on-air command of the material of the ID is received by the program transmission server BS via the control network 5 during the re-recording and recording. Needless to say. Further, the present invention can be applied to a configuration obtained by changing or combining the configurations and processing procedures of the above-described embodiments and modifications without departing from the gist thereof.

As described above, according to the program transmission server according to the embodiment of the present invention, an on-air command is issued during re-recording by assigning a temporary ID to the material to be re-recorded and replacing it with the original ID when the writing / recording is completed. Even if it is received, the already recorded material is sent out, so that it is possible to prevent the occurrence of a broadcast accident and easily re-record without being caught by on-air timing.
