04 is provided.

In this system, since music is broadcast to each user via a satellite, a CD is used as an information source. The information source management system 11 manages the CD (medium) and the music recorded on the CD as a sound source. For this reason, the information source management system 11 has a CD inventory management server 21. The CD inventory management server 21 includes a hard disk (mirror disk 22),
An MO autochanger 23 is connected. Necessary information is registered in the hard disk 22 and the MO disk driven by the MO autochanger 23 to form a database.

Other media such as DATs, compact cassettes, and records are also managed.

The set of CD inventory management server 21 has a hard disk 22 in a mirroring configuration, makes a full backup once a week using an MO disk, and backs up information (difference) inputted on that day every day. 1
Order with inventory management PC 24 as two clients
Carry in, enter information, search, and lend. The maximum amount of stored information is one million for music.

The material information management / progress organization system 12 comprises:
It is composed of two sets of knitting servers 41-1 and 41-2 and 15 sets of knitting PCs 42-1 to 42-15 connected thereto. The knitting servers 41 each have a hard disk 41A. This material information management and progress organization system 12 manages music that contributes to broadcasting,
Organize the progress table. This progress table records the material to be broadcast, the broadcast start time, and the broadcast interval. The material information of the music necessary for broadcasting and the progress table for each channel are all stored in the hard disk 41A of the composition server 41. Here, the material refers to the music that has been converted into a file by MPEG compression (encoding), and the material information refers to the material encoded by the material information registration system 13.
Or, there is an encoding request, which refers to information on materials necessary for broadcasting.

Material information management and progress organization are performed as follows. The organizer creates a progress table of the channel in charge of himself from the knitting PC 42.

1. The organizer searches the material information of the formation server 41 for the music to be broadcast. If the target material is found, the music is dragged to the composition frame on the GUI of the composition PC 42. At this time, the performance time of the dragged music is the actual time when broadcasting. This song is "recorded" in the composition frame.

2. The organizer searches the CD inventory management server 21 if the target material is not found as a result of searching the material information of the organization server 41 for the music to be broadcast.
If the target music is found, on the GUI of the composition PC 42,
Drag the song to the composition frame. At this time, the performance time of the dragged music is a time on the CD inventory management, and the time of the recorded result may be different from this. In this case, since the material information has not yet been registered (encoded), the music piece is "not recorded" in the composition frame. Unrecorded songs are sequentially notified as recording candidates to the material information registration system 13, and as soon as they are encoded, "unrecorded" is changed to "recorded" material on the composition server 41. The performance time is the actual time when broadcasting.

If the target music is not found by searching the CD inventory management server 21, a CD ordering request is output to the CD inventory management server 21, and then a temporary candidate is set. As soon as it is completed, encoding is performed through the above-described procedure, and finally all the songs become “recorded” in the composition frame.

3. At the time when all the songs are “recorded” on the composition frame, the composer checks the consistency on the GUI of the composition PC 42. In the consistency check, the materials specified in the composition frame are evenly allocated, and it is automatically checked whether the reproduction time and the inter-song (silence) time are within specified values. For example, if it is attempted to broadcast 12 songs of about 5 minutes in a one-hour program, and if 11 songs are exactly 5 minutes and 1 song is 6 minutes, the total playback time exceeds the composition frame (1 hour). Also, if all songs are exactly 5 minutes, there will be no silence between the songs, which makes the broadcast unnatural. Therefore, the lower limit value (for example, 1.5 seconds) and the upper limit value (for example, 3 seconds) of the time between songs (silence) when broadcasting the material.
Is set, and when all songs are allocated equally, it is checked whether the time between songs (silence) is within this range. If it does not fit, replace the material with a different playing time, or insert a material for time adjustment prepared in advance at the end of the knitting frame as a short knitting so as to pass the check.

FIG. 4 shows a flowchart of such a consistency check process. First, in step S1, a consistency check process is started, and in step S2
In, it is determined whether or not all songs have been recorded. If it has been recorded, the material to be checked for consistency has been determined, so the process proceeds to step S3, where the upper limit value and the lower limit value between songs are input. For example, 3 seconds is input as the upper limit between songs, and 1.5 seconds is input as the lower limit between songs.

Next, in step S4, an equal allocation calculation is performed. For example, as shown in FIG. 5A, the composition frame is one hour (3600 seconds), and during this broadcast time, the music A
Or broadcast the song L. Since the total of the performance (reproduction) times of the songs A to L is 3437 seconds, the total time between the songs is 163 seconds (= 3600−3437).

Therefore, the total time between songs is determined by the number of songs (= 1
When divided by 2), 13.58 seconds (= 163 seconds / 12) is obtained as the average time between songs.

Next, the process proceeds to step S5, where it is determined whether or not the interval between songs is within the upper limit. In this case, the interval between songs is 1
3.58 seconds, exceeding the upper limit (3 seconds). In this case, the process proceeds to step S6, and the recommended replacement music time is displayed.

In this case, the total of the upper limit time between music pieces is 36
Seconds (= 3 seconds × 12), and the total of the lower limit time between songs is 1
8 seconds (= 1.5 seconds × 12). Accordingly, the minimum performance increase time is 127 seconds (= the total time between music pieces 136 seconds−the total upper limit time between music pieces 36 seconds), and the maximum performance increase time is 145.
Seconds (= Total time between songs 163 seconds-Total lower limit time between songs 18 seconds)
Becomes Therefore, for example, "2 minutes 07 seconds (127
Seconds) to 2 minutes 25 seconds (145 seconds).

Therefore, in step S7, the organizer performs reorganization processing such as replacing a predetermined song with a longer song.

For example, as shown in FIG. 5, when a song L having a length of 2 minutes is changed to a song M having a length of 4 minutes 10 seconds (250 seconds),
Since the music M is longer than the music L by 2 minutes and 10 seconds (130 seconds), as shown in FIG. 5B, a total of 12 music A to the music K and the music M are equally spaced (2. 75 seconds).

If it is determined in step S5 in FIG. 4 that the interval between songs is within the upper limit, the process proceeds to step S8, and it is determined whether the interval between songs is within the lower limit. If the interval between the music pieces is within the lower limit, the process proceeds to step S11, and the consistency check is completed.

On the other hand, if it is determined in step S8 that the interval between the songs is not within the lower limit, the process proceeds to step S9, and the recommended replacement song time is displayed. Then, in step S10, the organizer performs a reorganization process such as replacing the song with a shorter song. For this reason, songs of various lengths are prepared in advance, and the holding server 121 described later.
Registered in.

If it is determined in step S2 that all the music pieces to be checked for consistency have not been recorded, the process proceeds to step S12, where the unrecorded music pieces are changed to the composition PC.
42 is displayed. In this case, since the equal allocation calculation cannot be performed, the process proceeds to step S13, and the process ends without performing the consistency check.

The playing time of these materials is calculated based on the time of the material information database (encoded material) on the composition server 41, not the time of the database of the CD inventory management server 21.

In this way, a progress table (file) for one day for one channel is created. Finally, the composition manager approves the progress table, and the approved progress table (file) is locked so as not to be rewritten, and is stored in the external hard disk 121A of the possession server 121 of the sending site 2.
Is transferred using the dedicated line 3.

4. In this way, the composition server 41 stores the progress table as a database for each channel and for each broadcast date. Also, the composition server 41 has, as material information, data on the material already stored as broadcast material on the external hard disk 121A of the possession server 121 and a broadcast schedule in the future, and should be stored on the external hard disk 121A of the possession server 121. Data on unrecorded material is accumulated as a database.
These data are stored based on data obtained by extracting items necessary for broadcasting from the database of the CD inventory management server 21 and added with information on broadcasting such as a broadcasting date, a broadcasting channel, and an organizer. .

The two sets of composition servers 41-1 and 41-2 have external hard disks 41A-1 and 41A-2, respectively, and operate in dual operation. 15-type knitting PC42-
In steps 1 to 42-15, a composition table is created by searching the composition server 41, searching the CD inventory management server 21, and the like. The maximum storage information amount of the composition server 41 is 100,000 for the material.

The material information registration system 13 uses an eight-CD

The registered PCs 53-1 through 53-8 also have
Eight live PCs 61-1 to 61-8 are connected. These live PCs 61 have their hard disk 6
In 1A, live data is stored. The data output from the live PCs 61-1 to 61-8 is MP
After being decoded by the EG decoders 62-1 to 62-8, the codecs 123-1 to 124-8 of the transmission site 2 are transmitted from the codecs (CODEC-Decoders) 63-1 to 63-8 via the dedicated line 3. To be supplied.

At this time, the outputs of the MPEG decoders 62-1 to 62-8 are appropriately added to the inputs from the microphones 76-1 to 76-8 and output from the codec 63.

An archive MO changer 55 is connected to the archive control PC 54.
Archive data is stored in the MO disk driven by the changer 55. The archive control PC 54 includes a registration PC 53 and a live PC 6

, The DSU 125-2, the terminal adapter 126-2, and the router 127-2 of the sending site 2 are also connected to the possession server 121.

The material information registration system 13 is, for example, a CD

This is a system that realizes a function of playing music through one route.

As a result of searching the material information of the composition server 41 for the music that the organizer wants to broadcast in the material information management / progress composition system 12, the target material is not found. The CD inventory management server 21 is searched and the target material is searched. If you find
The music is dragged to the composition frame on the GUI of the composition PC. In this case, still register the material information (encode)
Since this is not done, this song is "unrecorded" in the composition frame. Therefore, the unrecorded music is notified to the material information registration system 13 via the dedicated line 3 as a recording candidate.

The person in charge of material information registration reserves a music piece to be registered from among the music pieces that have not been recorded, that is, material registration candidates. This is to prevent duplication of work with other persons at the same time. After making a reservation, the person in charge of material information registration goes to a lending window of the information source management system 11 and borrows a necessary CD medium. At this time, the knitting PC4
The material information extracted on the CD inventory management server 2
Since it is based on one database, the target CD medium can be immediately pulled out by the CD medium management number.

At the booth where the material is registered, a check is made to electronically collate the music of the material registration candidate with the music of the actually borrowed CD medium. This is C
D When performing inventory management registration, a value that is uniquely determined for a song determined by a certain arithmetic expression from a playing time and a track number for one song is calculated, and the calculated value is stored in a database as a collation ID. Since it is stored, when it is actually borrowed, it can be realized by whether or not the value obtained by the calculation again matches.

The confirmed music is applied to the CD player and the amplifier 51, encoded in real time by the MPEG encoder decoder 52, and stored as an MPEG file on the hard disk 53A of the registered PC 53. The file (material) for which writing has been completed is transferred to the external hard disk 121A of the possession server 121 of the sending site 2 using the dedicated line 3. Furthermore, the server 12 of the sending site 2
The file (material) stored in the first external hard disk 121A is transferred to the hard disk 53A of the registered PC 53 of the formation site 1 using the dedicated line 3. The person in charge of material information registration reproduces the file (material) transferred from the possession server 121 by the MPEG encoder / decoder 52, and performs an audition to listen to the sound from the beginning to the end. The material that does not cause any problems after the audition work becomes "recorded".

The conversion of the music to an MPEG file can be realized by the methods shown in FIGS.

1. In the method shown in FIG. 6, music (baseband) is reproduced by a real-time reproducing apparatus 201 (for example, a CD player) as the CD player and the amplifier 51, and is compressed by a real-time encoder 202 as an MPEG encoder decoder 52. The hard disk 5 of the registered PC 53
Store in 3A.

2. In the method shown in FIG. 7, data is read by a CD player and an N-speed playback device 211 serving as an amplifier 51, for example, an 8 × -speed CD-ROM player.
The data is compressed by an 8 × speed encoder 212 serving as an MPEG encoder decoder 52 and the hard disk 5 of the registered PC 53 is compressed.
Store in 3A. N is a number including a decimal number greater than one.

3. In the method shown in FIG. 8, data is read by a CD player and a variable-speed playback device 221 (for example, a CD-ROM player) as the amplifier 51, and the data is temporarily stored in an internal memory of the directly registered PC 53 or the hard disk 53A. And stores it in the hard disk 53A. Note that the variable speed here includes burst read control.

4. In the method shown in FIG. 9, when a file already encoded is externally supplied, the registered PC 53
In the hard disk 53A.

In the material information registration system 13, the possession server 121 sends the router 127-2 and the terminal adapter 1
26-2, DSU 125-2, leased line 3, DSU 71-2,
The file (material) transferred via the path of the terminal adapter 72-2, the router 73-2, and the live PC 61 is stored in an MPEG format.
The method of decoding and reproducing by the decoder 62
(Disc jockey) performs live broadcast music transmission. The composition server 41 searches the composition server 41 for the music to be broadcast from the live PC 61 as a DJ terminal, and checks whether or not the desired music has already been recorded. The material is transferred from the possession server 121 of the transmission site 2 via the dedicated line 3, and the music is reproduced (decoded) by the decoder 62. At this time, the audio signal collected by the microphone 76 is A / D converted and superimposed (mixed) on the output of the MPEG decoder 62.

Further, since the capacity of the external hard disk 121A of the high-speed and expensive possession server 121 is limited, it will eventually be saturated. Therefore, the capacity of the external hard disk 121A of the possession server 121 is constantly monitored, and the deletion candidate material is displayed on the archive control PC 54 according to the set conditions. The condition is, for example, that the number of broadcasts is 1
This includes materials that have been used twice or less within a year, and songs that have been designated as deletion candidates after the broadcast has ended. Conversely, a material designated in advance not to be listed as a deletion candidate at the time of material registration is excluded from the deletion candidates. When the material manager designates the music to be actually deleted from these deletion candidates, the music to be archived on the MO disk, and the music to be excluded from the deletion candidates, the processing is automatically performed. The songs archived on the MO disk of the archive MO changer 55 can be returned to the external hard disk 121A of the possession server 121 by batch processing when necessary for organization. For this reason, the possession server 121 and the archive control PC 54 communicate with the router 127-2, the terminal adapter 126-2, the DSU
125-2, a dedicated line 3, a DSU 71-2, a terminal adapter 72-2, and a router 73-2.

FIG. 10 shows details of the archiving process. That is, first, in step S31,
The archive control PC 54 or the registered PC 53 sets conditions for archiving. As described above, this condition can be, for example, a song whose broadcast frequency is two or less within the past year. At this time, the archive control PC
The process 54 proceeds to step S32, searches the organization server 41 for a material whose number of broadcasts is two or less within the past year, and displays the material on the archive control PC 54 or the registered PC 53 as a deletion candidate.

Next, the process proceeds to step S33, where
The material manager designates the material to be actually deleted from the materials of the deletion candidates displayed at 32. When this designation is made, in step S34, the archive control PC 54
Performs a process of deleting a material designated to be deleted from the registration of the holding server 121.

Next, in step S35, the material manager designates an archive material from among the deletion candidate materials. When this designation is made, the archive control PC 54
In step S36, the material registered in the holding server 121 is copied to the MO of the archive MO changer 55.
Archive to disk.

As a result, the materials can be separately stored on the hard disk 121A, which is high-speed but has a small capacity, and the MO disk which is slower but has a larger capacity than the hard disk 121A. The size and cost can be reduced as compared with the case of storing.

In this way, the eight registered PCs 53-1 through 53-8 know the material registration candidates in the database of the composition server 41, and the eight encoder decoders 52-1 through 52- connected to each registered PC 53. At step 8, the material is filed. The set of archive control PCs 54 (clients) knows the material of the deletion candidate in the database of the composition server 41 and deletes them from the registered PC 53 or archives them to the MO disk of the connected set of archive MO changers 55. . The eight live PCs 61-1 to 61-8 (clients) know the recorded materials in the database of the composition server 41, and the eight live decoders 62-1 to 62-8 connected to the live PCs 61-1 to 61-8.
At -8, the music is reproduced.

Even if the material has been archived once, if the material is used on the progress table again, it is necessary to cause the holding server 121 to hold the material again. That is, as described above, when a material is designated on the progress table, it is checked whether or not the material has been recorded. Materials that have not been recorded need to be recorded, but archived materials are those that have already been recorded. The knitting server 41 manages material information in a database formed on the hard disk 41A. When the material is an archived material, the knitting server 41 also stores the recording position of the archive MO changer 55 for the material. ing.

Therefore, when it is determined that the material specified on the progress table is an archived material, the knitting server 41 executes an archive control by a batch process when a predetermined time comes. Controls the PC 54 and is held in the archive MO changer 55;
The material is read, transferred to the holding server 121, and held.

Of course, the organizer manually operates the archived material as needed to store the archived material.
It is also possible to transfer the data to the storage device 21 and hold it.

Further, the archive material specified on the progress table is automatically batch-processed into the holding server 1.
It is also possible to make a selection as to whether to stop or continue the function transferred to and retained by the control unit 21 as needed. By doing so, it is possible to prevent the archived material from being erroneously restored to the holding server 121.

The owned server and the multi-channel transmission system 101 include two sets of owned servers 121-1 and 121-2.

The system configuration file stored in the possession server 121 is as follows.

Common time: The entire sending system shares the correct time. -Bit rate table: Defines the bit rate of the music channel to be transmitted. -Channel combination table: Defines the channel that the sending server 123 is responsible for. MUX working state: Indicates the working system of the secondary multiplex satellite transmission system 102. -PMT: Program Map Table-Service Correspondence Table: Correspondence table of management channel numbers and broadcast service numbers.

The sending system here means the organization server 41, the possessing server 121, the sending server 123, the switching control PC 182, and the multiplexer controller (hereinafter, referred to as MXC) 144. Among these, the common information of the transmission system can be stored in the possession server 121, and can be referred / updated at any time during operation of the system.

FIG. 11 shows the relationship between the server for setting these configurations and the server to be referred to.

The bit rate table, PTM, and service correspondence table define system basic parameters, and are not changed during normal operation. The channel combination table and the MUX working state are not changed during normal operation, but the sending server 123 serving the channel group is changed at the time of failure or maintenance.

In these configuration files, the update date and time are recorded in the head comment line, and the reference side can know the presence or absence of the update from this.

In the following description, “management channel number”
Are numbers corresponding to internal channels of the system, and are serial numbers from 1 to 100.

<Common Time> The switching control PC 182 periodically sets and corrects the common time of the owned server 121 based on the time measured by the internal clock 184. The sending server 123 and the MXC 144 use the rda
By executing the te command, the time of the entire transmission system can be adjusted.

<Bit Rate Table> The bit rate table indicates the transmission bit rate of each channel and whether the transmission is from the material file held in the holding server 121 or the transmission from the MPEG encoder 129 in real time. , And a music genre to be broadcast as an annotation. This is set by the switching control PC 182, and is referred to by the composition server 41 and the sending server 123.

<Channel Combination Table> This channel combination table is a file that defines a management channel for one transmission server 123. This is the switching control P
C182 sets by ftp (file transfer protocol),
The sending server 123 and the MXC 144 refer.

<MUX working state> This indicates the working system of the multiplexer (MUX) 141 of the secondary multiplex satellite transmission system 102 having a dual system structure, which is set by the switching control PC 182 and referenced by the MXC 144.

<PMT (Program Map Table)> PMT
Is a file that defines map information assigned to each channel of the broadcast. This is updated daily by the MXC 144 by ftp, and is referred to by the sending server 123.

The transfer procedure of the PMT is as follows. Time t1 [MXC144 → owned server 121] PMT for next day
Ftp transfer time as PMT.new Time t2 [Owned server 121] If PMT.new exists, PMT
Time t3 [Sending server 123] Broadcasting end of the day Time t4 [Holding server 121 → Sending server 123] P
MT copy time t5 [Sending server 123] Broadcast start the next day

The broadcast time is from time t0 to time t6.
Up to one day (one cycle), and the time t1 of the above procedure
To t5 are predetermined times during that period.

The possessing server 121 checks for the existence of a new PMT (PMT.new) at a predetermined time every day, and if there is, the file name is changed to PMT.
Received by setting to T. The sending server 123 copies the PMT prior to the start of daily broadcasting. At this time, if there is a failure in the possession server 121, it is transmitted using the PMT copied on the previous day.

<Service Correspondence Table> This table shows the correspondence between the management channel numbers and the “channel numbers” assigned on the broadcast service.
The sending server 123 and the MXC 144 refer.

<How to change the configuration file> To update the following files, add the suffix (.new)
From the switching control PC 182 to the possession server 121
ftp transfer.・ Bit rate table: /100ch/config/bitrate.new ・ Channel combination table: /100ch/config/Channel.new ・ Service correspondence table: /100ch/config/service.new

The possessing server 121 checks for the existence of these updated files every day at a predetermined time immediately before the end of the broadcast, and receives them by changing the file names without the suffix if any.

The transmission server 123 copies the received file (ie, the file without a suffix) before starting the daily broadcast. At this time, owned server 1
If there is a failure at 21, the one copied the previous day is valid.

FIG. 12 is a flowchart showing the process of changing (updating) the configuration file. First, in step S41, the possession server 121 determines whether there is a file to which the suffix (.new) is added. If such a file exists, the process proceeds to step S42. Execute file replacement processing.

That is, the possessed server 121 stores the (.ne
The file with the file name excluding the suffix of w) is updated with the contents of the file with the suffix. For example, AB
C. If new file exists, file ABC
Is the file ABC. Updated with new. Then, the updated file name is ABC.

After such a file replacement process is performed, the process proceeds to step S43. In step S41,
If it is determined that there is no file having the suffix of (.new), the process of step S42 is skipped, and the process proceeds to step S43. In step S43, the file updated in the holding server 121 in this way is copied to the sending server 123, and the sending server 123 broadcasts according to the content.

In the present embodiment, the sending server 123
Are nine, eight of which are active and one is spare. The transmission server 123 receives as input a material file of a plurality of channels (up to 13 channels in the present embodiment) from the possession server 121 or a material stream from a real-time encoder 129 that performs MPEG compression (encoding) processing in real time. In real time, it is converted into a transport stream (TS) of the MPEG system standard by software and multiplexed.

The sending server 123 also multiplexes a PMT (program map table) and a PCR (program clock reference) at the same time. This is called first-order multiplexing.

In the case of broadcasting 100 channels in total as in the present embodiment, among the eight transmission servers 123,
6 formulas are 13 channels, 1 formula is 12 channels, and the remaining 1
The equation linearly multiplexes ten channels. It is converted into an electric signal, and two multiplexers (MUX) 141-1, 1 for the working system and the spare system for the secondary multiplex satellite transmission system 102 are used.
Output in parallel to 41-2. Further, a similar output is
The data is also output to the audio monitor 163 in parallel. All the electric signals flowing through the cables of these transmission paths are transmitted to the transmission server 12.
3 to the multiplexer 141 and the TS audio monitor 163. The contents are TS data, clock, sync,
Data valid.

The sending server 123 changes daily (4:00).
In accordance with the progress table for a plurality of assigned channels for the current day acquired on the previous day, files of materials necessary for broadcasting are sequentially read from the external hard disk 123A of the transmission server 123, and at the same time, MPEG compression is performed in real time by the MPEG encoder 129. After converting the (encoded) processed material stream into a transport stream packet of the parallel MPEG system standard, creating a PMT (program map table) packet, inserting a null packet, and then inserting a PCR (program clock reference) ) After multiplexing the packets, time information is imprinted on the PCR packet and output.

The sending server 123 further supplies
The progress table for the plurality of assigned channels for the next day is read from the possession server 121, and the materials necessary for broadcasting the next day are copied from the possession server 121 to the external hard disk 123A of the transmission server 123 according to the progress table. Accordingly, in the event that a failure occurs in the possessed server 121 or the transmission of the progress table is delayed, the response can be deferred until the next day. Also, for more than 2 days, own server 1
If a failure occurs in 21 or the progress table is not sent, by replacing (copying) the progress table for the previous day on that day, it is possible to prevent an accident that the broadcast is not executed at all. .

In the present embodiment, the capacity of the external hard disk 123A of the sending server 123 is stored for two days. The occupied capacity of the disc is smaller when materials are overlapped, such as for today and the next day, than when materials that do not overlap at all in each channel and in all channels are broadcast. That is, as an extreme case, when one material is continuously broadcasted for two days in all the channels, the occupied capacity of the disk may be only one material file. Further, depending on the operation, a specific channel may have a shorter organization and a specific channel may have a longer organization.

If a failure occurs in one of the eight transmission servers 123 and transmission becomes impossible, all channels (for example, 1
Broadcast of (3 channels) stops. Therefore, all the processes being executed on the failed sending server 123-i are switched to the spare sending server 128-j (9/8 redundant switching is performed). Switching control PC 182 described later
Rewrites the configuration of the possession server 121, and then notifies the sending server 123 and the MXC 144 that the configuration has been rewritten. The sending server 128-j waiting as a spare acquires the progress table of the channel which the failed sending server 128-i was in charge of from the possessing server 121, and according to the progress table, the material file required for the current sending. Is read directly from the possession server 121 and transmission is started. At the same time, MXC1
44 switches the input channel of the MUX 141. That is, the input gate of the failed MUX 141 is closed, and the previously closed input gate is opened as a spare. As a result, broadcasting is immediately started (recovered).

In the meantime, the sending server 123-j
Searches for a material file necessary for today and the next day from the progress table of the channel in charge, reads it out from the possession server 121, and reads it from the external hard disk 123.
A-j is sequentially copied. In other words, since the transfer time of the file from the possession server 121 to the transmission server 123 is earlier than the reading of the material file to be transmitted, what is to be transmitted is transmitted without waiting for the completion of copying of all the materials, In the meantime, the copy is completed. As a result, the sending server 123-j that has been waiting as a backup finally has exactly the same settings as the sending server 123-i that has failed. This eliminates the need to return the standby unit to the active unit after the replacement has occurred due to a failure, and thereafter causes the failed transmission server 123-i to stand by as a standby unit,
It will be possible to repair it.

[0110] The secondary multiplex satellite transmission system 102 is shown in FIG.
As shown in FIG. 3, a transmission system A system 311 and a transmission system B system 312 are provided. Transmission system A system 311

2-1 modulates the input data by the QPSK method and outputs the modulated data to the selector 143.

Similarly, the multiplexer 141-2 constituting the transmission system B system 312 is controlled by the MXC 144-2, selects the output of the transmission server 123, and outputs it to the modulation device 142-2. The modulation device 142-2 modulates the input signal by the QPSK method and outputs the modulated signal to the selector 143.

It should be noted that DVB (Digital Video Broadcast) is transmitted from the sending server 123 to the MXC 144 and the TS audio monitor 163.

The selector 143 is controlled by the switching control PC 182, and is controlled by the modulation device 142-1 or the modulation device 14-1.
One of the signals input from 2-2 is selected and output to a satellite via an intermediate frequency (IF) processing circuit (not shown).

The multiplexer 141 and the MXC 144
, A predetermined signal is appropriately supplied from a broadcast management system 301 that manages the entire broadcast.

In the secondary multiplex satellite transmission system 102, 8
A TS in which PES (Program Elementary Stream) packets, PMT packets, and PCR packets for 13 channels, which are respectively supplied from the transmission server 123 of the system, are primarily multiplexed, is input to the multiplexer 141. The multiplexer 141 as a secondary multiplexing device multiplexes these packets and all packets to be transmitted to the satellite, such as packets necessary for selecting a program other than the PMT, a program guide packet, a program management packet, and a customer management packet, and outputs them. . The output is subjected to QPSK modulation after an error correction code is added by the QPSK modulator 142, and output as a modulated signal.

Multiplexer controller (MXC) 14
4 receives the operation data for the next day (specifying the operation of the whole broadcast) from the broadcast management system 301 every day at 26:30, creates a PMT file at 27:50, and stores the PMT file as PMT.new through the hub 122. Transfer to 121. The MXC 144 also provides the multiplexer 141 with a packet required for selecting a program other than the PMT, a program guide packet,

FIG. 14 shows the configuration of the peripheral device as viewed from the working MXC 144. FIG. 14 shows a case where transmission or reception is viewed from the working MXC 144-1 (or 144-2) arranged at the center.

The MXC 144 is an MXC 144-1 (MXC-A)
And MXC144-2 (MXC-B).
The A system and the B system after C144 are controlled independently, but only the active MXC 144 is connected to the transmission server 123 via the hub 122 and the TS audio monitor 1 via the hub 303.
63, a hub 303 and a channel setter PC16.
2, the control information is sent to the switch console 341 of the multi-channel monitor 161 of the multi-channel monitor system 103 (FIG. 13). Recognition of the working and the backup is performed by the configuration on the holding server 121.

One of the main roles of the MXC 144 is to set various parameters, and to set initial parameters. After that, the MXC 144 does not participate in transmission operation unless there is an abnormality. Another role is abnormality monitoring, which monitors each peripheral device and notifies the alarm PC 183 of an abnormality (alarm).
In response to a switching instruction from the switching control PC 182, switching control is performed in accordance with the configuration on the owned server 121 (FIG. 14).

The MXCs 144-1 and 144-2 are, for example,
Every 5 minutes, a request for writing dummy data is issued, the execution is confirmed, etc.
In the case where the alarm of the active MXC is notified from C to the alarm PC 183, the observer (person) judges this and switches the switching control PC1.
82 is controlled to switch between the working and the spare.

The role of the working MXC 144 is described below. -Reception of various transmission control information from the broadcast management system 301-Transmission of the PMT file to the possession server 121-Receiving the configuration from the possession server 121, such as time and current / preliminary designation-Notification of abnormality to the alarm PC 183-Switching Receiving switching instruction from control PC 182 ・ Setting and monitoring of active MUX 141 Switching of input channel of active MUX 141 when transmission server 123 is abnormal Transmission of input channel error of active MUX 141 ・ Setting and setting of active QPSK modulator 142 Monitoring ・ Monitoring of standby MXC 144 ・ Setting and monitoring of TS audio monitoring device 163 ・ Setting and monitoring of channel setter PC 162

The role of the spare MXC 144 is described below. -Reception of various transmission control information from the broadcast management system 301-Reception of the configuration such as the time and current / preliminary designation from the holding server 121-Notification of abnormality to the alarm PC 183-Receiving the switching instruction from the switching control PC 182-Standby Setting and monitoring of the MUX 141 Switching of the input channel of the standby MUX 141 when an error occurs in the transmission server 123 Transmission of an error of the input channel of the standby MUX 141 ・ Setting and monitoring of the standby QPSK modulator 142 ・ Monitoring of the active MXC 144

Multiplexer 141, QPSK modulator 14
2 and MXC 144, as described above,
There are formulas and they operate completely independently in parallel. each
The output of the QPSK modulator 142 is supplied to the selector 143, and the switching control PC 182 performs this switching. As a result, the active system and the standby system are switched (A / B switching). MX
The C144 independently transfers the settings and schedules to the respective MUXs 141. The transmission of the PMT file to the possession server 121, the settings and monitoring of the TS audio monitor 163, and the settings and monitoring of the channel setter PC 162 are as follows.
Only the working MXC 144 performs this.

The multi-channel monitor system 103 has a multi-channel monitor 161. The multi-channel monitor 161 includes modulation devices 142-1 and 142-2.
And the output of the TS audio monitor 163 are supplied. Further, the multi-channel monitor 161 is supplied with a reception IF signal obtained by receiving a radio wave from a satellite by a receiving device (not shown) and demodulating the radio wave. Further, the multi-channel monitor 161 has an OA listening PC 16
5 is decoded by the MPEG decoder 166,
Supplied. The multi-channel monitor 161 can appropriately monitor these inputs. The channel setter PC 162 controls the multi-channel monitor 161.

The multi-channel monitor system 103 is a system for monitoring whether all channels are correctly transmitted. First, a radio wave transmitted from a satellite is received, distributed to IRDs (not shown) as 100 receiving devices, and sound is reproduced by each IRD, and a peak corresponding to 100 channels of the multi-channel monitor 161 is obtained. Display all at once on the level meter. The observer can know the transmission status at a glance by the movement of the meter. Further, the multi-channel monitor 161 is provided with a level detecting device 161A,
When the condition of -50 dB or less (silence) continues for 30 seconds or more, the indicator on the peak level meter blinks red and an alarm sounds to alert the observer. The observer knows this and can select the channel and output a sound to the speaker to investigate whether there is a failure. The threshold value and the detection time setting of this level can be changed.

When an abnormality is detected in the transmission system of the satellite, the inputs to the multi-channel monitor 161 are all
The output from D (CS-IF) is switched to the output of the working QPSK modulator 142, and the sound before satellite transmission is confirmed by a 100-channel peak level meter and one sound selected by the switch console 341. Do. If necessary, switch to the output of the standby QPSK modulator 142 to convert the sound before satellite transmission to a 100-channel peak level meter,
Confirmation is performed by one selected voice.

If there is a further problem, the output of the sending server 123, that is, the MUX
A 1-channel transport stream (TS) is extracted (demultiplexed) from the primary multiplexed stream before being input to 141, and is decoded 164 (FIG. 3).
, And a confirmation is made using the peak level meter of 100 channels and one selected sound. In order for the transmission server 123 to simultaneously multiplex 13 channels per set, the TS audio monitor 163 simultaneously decodes up to 13 channels of TS per set and outputs 13 channels of audio. By equipping the TS audio monitor 163 with eight expressions (one expression out of nine is a spare), it is possible to simultaneously output audio of 100 channels.

Switch Desk 3 of Multi-Channel Monitor 161
41 has 100 selection switches, and its switch 1
Each one corresponds to a channel number. On the other hand, since the output of the TS audio monitor 163 physically corresponds to the output of each sending server 123, when 9/8 redundant switching is performed, the output of the TS audio monitor 163 does not correspond to the channel number. . Therefore, in this embodiment, the channel setter PC 162 sets which input is selected and output by the 100 selection switches of the switch console 341 of the multi-channel monitor 161 according to the switching information.

The channel setter PC 162 controls the switch console 341 of one set of multi-channel monitors 161. On the other hand, the setting file for controlling the selection switch is transferred from the two sets of MXCs 144. Is performed via a network using a LAN as the dedicated line 3, and the switch console 34 of the multi-channel monitor 161 is
1 is performed by RS-422 (FIG. 13).

If there is a problem before the sending server 123, there is a possibility that the material on the possessed server 121 is the cause. Therefore, the material file in question is directly sent from the possessed server 121 by the OA (On Air) listening PC 165. It can be read and decoded by the MPEG decoder 166 for confirmation. In FIG. 3, the OA listening PC
165 and MPEG decoder 166 are shown as playback device 265.

For example, when there is an abnormality in the broadcast and received sound, it is necessary to identify whether the recorded material itself has an abnormality or an abnormality has occurred during the transmission process.
Therefore, the OA listening PC 165 designates the day and channel on which the abnormality has occurred and displays the progress table. When an abnormal material is designated on the progress table, the OA listening PC 165 reads the designated material from the possession server 121 and reproduces the material. This makes it possible to determine whether or not the material itself has an abnormality.

The transmission management system 104 includes a switching control PC
182-1 and 182-2, and the switching control P
The output of the intra-office clock 184 that performs a clocking operation is supplied to C182. The transmission management system 104 also includes
OA monitor PC 181-1, 181-2, alarm PC
183.

OA monitor PC of transmission management system 104
181, switching control PC182, alarm PC183, O
The A listening PC 185 is connected to the MXC 144 of the secondary multiplex satellite transmission system 102.

The transmission management system 104 monitors and switches transmissions from the owned server and the multi-channel transmission system 101 and the secondary multiplex satellite transmission system 102. All alarms generated in each system are notified to the alarm PC 183. Here, chimes of four kinds of timbres sound according to the corresponding levels, and the alarm number and message appear on the display screen of the alarm PC 183. In addition, a corresponding method can be referred to according to the GUI. From this alarm PC 183, the alarm of each system
You can also see the LOG and know how the problem occurred. The system supervisor knows the abnormality by the alarm of the alarm PC 183. A failure condition and a response are determined from the display contents of the alarm PC 183, and a switching operation is performed from the switching control PC 182 as necessary.

Two types of switching control PCs 182-1 and 182-
Any one of the two is set to the active state, and the switching operation is set to the input enabled state. Switching control PC set as spare
The input of the switching operation cannot be performed from 182. The switching control PC 182 knows the correct time from the local clock 184 and sets it in the possession server 121. Each peripheral device obtains an accurate time by referring to the possessed server 121.
The switching control PC 182 performs switching of the transmission server 123 to the standby system (9/8 redundant switching) and switching of the output of the QPSK modulator 142 by the selector 143 (A / B switching) according to the input of the system monitor. At that time, the switching control P
C182 rewrites the configuration of the possession server 121, and then notifies each peripheral device that the configuration has been rewritten. Each peripheral device switches its operation by acquiring a new configuration from the possession server 121 using the trigger as a trigger.

The switching (A / B switching) of the output of the QPSK modulator 142 is performed according to an instruction from the switching control PC 182 by keeping the selector 143 remote. It is also possible to forcibly perform the switching on the front panel of the main body. In this case, the switching control PC 182 knows that switching has been performed by the selector 143 main body, and switches the configuration of the owned server 121 based on the information. Also, the transmission status of the music from the transmission server 123 is
It can be known from the OA monitor PC 181.

When an arbitrary channel is selected from the GUI on the OA monitor PC 181, a scheduled event (song) for the channel is displayed as a list (that is, the contents of the progress table). In addition, the song (event) being sent
The title, performer, playing time, remaining time are marked with a different color from the others, and the current sending status, past sending history,
The future transmission schedule can be known at a glance. Also, OA
Since the status of the monitor PC 181 is acquired from the sending server 123 and the event update is performed based on the operation of the sending server 123, it is also possible to know the abnormality / stop state of the sending server 123.

It is needless to say that the present invention is not limited to 100-channel music broadcasting, but can be easily applied to data broadcasting of all digitized information.

In the present embodiment, the MPEG system is used as the compression system, but this is merely for the sake of explanation.
Other compression schemes, such as AC, can be used. Further, the present invention can be applied even when compression is not used.

Although the present embodiment has been described on the assumption that the transmission path is a satellite, the transmission path may be a terrestrial wave, an optical space, an optical cable, a coaxial cable, or any other real-time transmission path. It may be a tape, an optical tape, a magnetic disk, an optical disk, or another storage type transmission path.

The present invention realizes an automatic transmission system for multi-channel data broadcasting.
