TECHNICAL FIELD OF THE INVENTION
The present invention is mounted on a movie content distribution management system for supplying movie content to a digital cinema server that stores movie content, a movie content distribution management server included in the movie content distribution management system, and a movie content distribution management server. It relates to a movie content distribution management program.
[0002]
[Prior art]
As a method of distributing movie content to a screening theater where a movie is shown, there is a method using a film or the like on which an analog signal is written. In this method, a film or the like is duplicated for each screening hall, and the duplicated film or the like is distributed to the screening hall by mail or brought manually.
[0003]
When the screening hall is a digital cinema theater that displays digitized movie content, the main method of distributing movie content is to use a DVD that records movie content. DVDs containing movie content may be distributed by mail or taken directly to Digital Cinema by a movie content distributor to prevent theft, and installed directly on a digital cinema server that holds digital cinema movie content. ing.
[0004]
The purpose of digitizing movie content is to ensure the quality of video and audio and to reduce operating costs including movie content distribution costs. However, since the distribution of movie contents using DVDs depends on humans, it is difficult to cope with an increase in the number of digital cinema screening theaters, contrary to the purpose of reducing operation costs.
[0005]
Therefore, a system using digital signals for recording movie contents and using a network such as the Internet for distribution has been devised (for example, see Patent Document 1).
[0006]
Also, an experiment of distributing movie contents using satellites has begun. However, for example, the file size of movie content for two hours is about 500 gigabytes or about 1 terabyte. Even if the compression ratio is increased at the expense of video quality, it exceeds 100 gigabytes, so that distribution using satellites with limited bandwidth takes more than one night. The screening hall will be closed during that time, which is a problem for a company that wants to change the movie content to be screened frequently.
[0007]
Therefore, a method of transmitting the content of a digital signal with a limited bandwidth has been devised (for example, see Patent Document 2).
[0008]
However, distribution using satellites can be received by anyone with the necessary equipment, and security problems are likely to occur.
[0009]
In a system for distributing movie content to a digital cinema server, movie content is encoded by an encoding method for compressing various data amounts, and is held and managed by a SAN (Storage Area Network).

[0011]
[Problems to be solved by the invention]
Various methods have been proposed and commercialized for compression for movie contents. However, as for the encoding method of movie contents, the standard to be standardized has not been determined, and various devices are in the stage of developing in proportion to the improvement of computer capability in order to obtain the status of a global standard for each standard. Therefore, in a screening hall equipped with a plurality of theaters, there is a problem in terms of cost in order to make all the theaters compatible with digital cinema, and at present, various commercialized devices are being purchased sequentially.
[0012]
Also, use of a digital cinema server for screening a concert or a show in order to increase the operation rate of a theater or for transmitting and displaying movie contents in real time at the expense of image quality has been considered. Therefore, for the advancement of equipment and compliance with standards, etc., the screening theater may have several types of digital cinema servers. It is uneconomical to install and operate a theater.
[0013]
The system described in Patent Literature 1 discloses a method of digitizing and recording movie contents and distributing the contents using a network. However, an efficient operation method in a situation where a plurality of compression standards exist is described. Nothing is disclosed.
[0014]
The method described in Patent Literature 2 also aims at cumulatively improving the quality of digital data received via a transmission path with a limited bandwidth, and is effective in a situation where a plurality of compression standards exist. It does not disclose any basic operation methods.
[0015]
Accordingly, the present invention provides a movie content distribution management system, a movie content distribution management server, and a movie content that can improve management efficiency by centrally managing and distributing movie content encoded by various encoding methods. The purpose is to provide a distribution management program.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0026]
Embodiment 1 FIG.
FIG. 1 is a block diagram showing an example of an embodiment according to the present invention. In this embodiment, the content storage server 1, the multimedia-compatible computer 2, and each digital cinema server are connected via a broadband network 3. The content storage server 1 receives and stores a content file including movie content encoded by the multimedia-compatible computer 2. The multimedia-compatible computer 2 is connected to each digital cinema server via the broadband network 3 and transmits and receives content information.
[0027]
The multimedia-compatible computer 2, which is a movie content distribution management server, is connected to the content storage server 1 via the broadband network 3, encodes the input movie content to compress the data amount, and encodes the encoded movie content. The content file including the content is transmitted to the content storage server 1. Each digital cinema server reads out the movie content stored in the content storage server 1 via the broadband network 3, performs a decoding process, and holds the decompressed movie content (uncoded movie content). Although FIG. 1 illustrates a system in which three digital cinema servers exist, the number of digital cinema servers is not limited to three.
[0028]
FIG. 2 is a block diagram illustrating a configuration example of the content storage server 1. In the content storage server 1, a control unit 11, a communication interface 12, and a hard disk array (hereinafter, referred to as a disk array) 14 are connected via a bus (BUS) 13, respectively. The control unit 11 controls each unit. The disk array 14 stores content files based on instructions from the multimedia-compatible computer 2. The BUS 13 is connected to the broadband network 3 via the communication interface 12.
[0029]
FIG. 3 is a block diagram illustrating a configuration example of the multimedia-compatible computer 2. In the multimedia-compatible computer 2, the control unit 31, the communication interface 33, the disk array 35, the A compression encoder 321, the B compression encoder 322, and the C compression encoder 323 are connected via a BUS 34. Note that the multimedia-compatible computer 2 includes encoders that perform encoding using an encoding scheme that can be handled by each digital cinema server connected via the broadband network 3. Here, an example in which three encoders respectively corresponding to the three types of encoding schemes are provided.
[0030]
Based on the control of the control unit 31, each encoder performs encoding using its own encoding method to compress the data amount of the input movie content, and generates a content file. For example, the A compression encoder 321 encodes the input movie content using an encoding method “A”, and the B compression encoder 322 encodes the input movie content using an encoding method “B”. Then, the C compression encoder 323 encodes the input movie content using the encoding method “C”. As the encoding method, for example, MPEG2 or JPEG2000 is used, but another original encoding method or a lossless encoding method may be used.
[0031]
The control unit 31 causes the encoder to encode the input movie content, and causes the encoder to generate a content file including the encoded content. Further, the control unit 31 determines a position where the content file in the content storage server 1 is stored. Then, the control unit 31 transmits the content file and the information indicating the file storage location to the content storage server 1 and stores the content file in the designated location. Instead of the control unit of the multimedia-compatible computer 2 determining the file storage position, the content storage server 1 may determine the file storage position and transmit information indicating the file storage position to the multimedia-compatible computer 2.
[0032]
Further, the control unit 31 includes information for specifying the movie content such as the title, information indicating the encoding method used for encoding the movie content, and the location of the content storage server 1 where the content file is stored. The information is generated and stored in the disk array 35. The communication interface 33 controls transmission and reception of data between the content storage server 1 and each digital cinema server via the broadband network 3. The content file is output to the content storage server 1, and information on the location of the content file is output to each digital cinema server in response to a request from each digital cinema server.
[0033]
FIG. 4 is a block diagram illustrating a configuration example of the digital cinema server 4 that supports A compression. The control unit 41, the communication interface 43, the disk array 45, and the A-compression compatible decoder 42 are connected via a BUS 44, respectively.
[0034]
The control unit 41 requests the multimedia-compatible computer 2 for information on the storage position of the predetermined content file encoded by the encoding method “A”. When receiving the information on the storage location of the corresponding content file, the control unit 41 extracts the content file at the corresponding location from the content storage server 1 via the broadband network 3.
[0035]
The communication interface 43 controls transmission and reception of data between the content storage server 1 and the multimedia-compatible computer 2 via the broadband network 3. The A-compression-compatible decoder 42 performs a decoding process on a content file encoded by the encoding method “A” to generate movie content.
[0036]
The B-compression compatible digital cinema server 5 is different from the A-compression compatible digital cinema server 4 in that a B-compression compatible decoder corresponding to the “B” system is provided instead of the A-compression compatible decoder 42. Differs from the A-compression digital cinema server 4 in that a C-compression-compatible decoder corresponding to the “C” system is provided instead of the A-compression-compatible decoder 42. Other configurations are the same. Hereinafter, the digital cinema server 4 corresponding to the A compression will be described as an example of each digital cinema server.
[0037]
In this embodiment, the movie content distribution management server is realized by the multimedia-compatible computer 2, and control means and content storage instructing means in the movie content distribution management server are realized by the control unit 31. The encoding means in the movie content distribution management server is realized by an A compression encoder 321, a B compression encoder 322, and a C compression encoder 323. The storage position management means is realized by the control unit 31 and the disk array 35.
[0038]
In the multimedia-compatible computer 2, the A compression encoder 321, the B compression encoder 322, and the C compression encoder 323 may be realized by hardware or software. In addition, since the function of the control unit 31 can be realized by software, when each encoder is realized by software, the multimedia-compatible computer 2 performs a process of encoding movie contents by a plurality of types of encoding methods. Processing for storing the encoded movie content in the content storage server 1, processing for managing the storage location of the encoded movie content in the content storage server 1, and requests from the digital cinema servers 4, 5, and 6 Accordingly, a movie content distribution management program for executing a process of notifying the digital cinema server of the storage position of the movie content encoded in the encoding format that can be handled by the digital cinema servers 4, 5, and 6 in the content storage server 1 is installed. The configuration can be as follows.
[0039]
Next, the operation of the present embodiment will be described. FIG. 5 is a sequence diagram illustrating a data flow according to this embodiment. First, the process of encoding content and storing it in the content storage server 1 will be described.
[0040]
When the movie content is delivered from the movie distributor, the administrator of the multimedia-compatible computer 2 inputs the movie content to the multimedia-compatible computer 2. Note that the movie content may be transmitted from the movie distribution company to the multimedia-compatible computer 2 via a communication network. When inputting movie content, the administrator also inputs information for specifying the input content. The information for specifying the content is, for example, the title of the movie content.
[0041]
The control unit 31 causes the A-compression encoder 321, the B-compression encoder 322, and the C-compression encoder 323 to encode the input movie content, and generates a content file including the encoded movie content. Then, each content file is transmitted to the content storage server 1 and stored in the content storage server 1.
[0042]
The control unit 31 may receive, from the administrator of the multimedia-compatible computer 2, an instruction as to which encoding method should be used to encode the movie content. At this time, the control unit 31 specifies an encoder that performs encoding in accordance with the instruction, specifies the encoder, and causes the encoder to encode the content. For example, when the encoding in the “A” system is instructed, the control unit 31 causes the A-compression-compatible encoder 321 to compress the data amount, which is an encoding process.
[0043]
The information of the position where the content storage server 1 stores the content file is information indicating a folder name, a directory name, or a physical track number of the disk array 14, and the method by which each digital cinema server accesses the content file. Is information indicating Then, for example, the administrator of the multimedia-compatible computer 2 gives the control unit 31 information on the position where the content file is stored. Alternatively, the control unit 31 automatically secures information on the position where the content file is stored in a free area of the content storage server 1. Alternatively, the content storage server 1 may secure information on the position where the content file is stored in the free space. In this case, the content storage server 1 returns information on the position where the content file is stored to the control unit 31 of the multimedia computer 2.
[0044]
For example, the administrator inputs a content “content 1” and compresses the content file using the “A” method so that the content file is stored in a folder named “mpeg2” in the “content1” folder of the content storage server 1. Suppose you receive instructions from
[0045]
The control unit 31 outputs the content file “content 1” compressed by the “A” method to the content storage server 1. Here, based on the instruction of the administrator, the content storage server 1 is instructed to store the content in the “mpeg2” folder in the “content1” folder.
[0046]
When the content storage server 1 receives the content file and the storage location instruction from the multimedia-compatible computer 2, the control unit 11 stores the content file in the disk array 14. The storage location is the location specified by the multimedia-compatible computer 2.
[0047]
In addition, the control unit 31 associates information for specifying the input content, information on the encoding method used for encoding the movie content, and information on the storage location of the content file in the content storage server 1. Content information, which is information, is generated and stored in the disk array 35. For example, the disk array 35 stores information that the content “content 1” compressed by the “A” method is stored in the “mpeg2” folder. FIG. 6 shows an example of a format in which the disk array 35 stores such information. FIG. 6 shows that the disk array 35 stores information in which the content “content 1” encoded in the “B” format is stored in the “jpeg2000” folder and “content 2” encoded in the “A” format. And the like in which the content “.” Is stored in the “mpeg2” folder. In this example, it is assumed that the “A” system is the MPEG2 system, the “B” system is the JPEG2000 system, and the “C” system is another system.
[0048]
Also, here, an example has been described in which the administrator gives information on the position where the content file is stored to the control unit 31. However, the control unit 31 automatically stores the content file in the free area of the content storage server 1. The control unit 31 can also generate the content information when securing the information on the location where the content file is to be stored or when securing the information on the location where the content storage server 1 stores the content file in the free space. When the content storage server 1 secures information on the position where the content file is stored in the free space, the control unit 31 receives the information on the position where the content file is stored from the content storage server 1.
[0049]
Next, a process from when each digital cinema server receives a content file to when a movie is shown will be described. Here, the operation when the A-compression-compatible digital cinema server 4 receives the content file “content 1” and performs the decoding process will be described as an example.
[0050]
The control unit 41 of the digital cinema server 4 supporting the A compression requests the multimedia-compatible computer 2 for information on the storage position of the “content 1” compressed by the “A” method. The control unit 31 of the multimedia-compatible computer 2 uses the information in the format as shown in FIG. 6 stored in the disk array 35 to convert the content “content 1” compressed by the “A” method into “mpeg2” folder “mpeg2” folder. The content that is stored in the file “content1.mpeg” is extracted, and the information is output to the digital cinema server 4 supporting A compression.
[0051]
Note that the multimedia-compatible computer 2 receives, in advance, decoder information, which is information on the corresponding encoding scheme, from each digital cinema server, and, for example, the digital cinema server having a format as shown in FIG. The information of the corresponding encoding method may be stored in the disk array 35. In this case, when the digital cinema server specifies the content and requests information on the position of the content folder, the control unit 31 reads out the decoder information and specifies the encoding method corresponding to the digital cinema server. . In that case, information on the encoding method is unnecessary in the content information. Then, the control unit 31 specifies the information of the position of the content folder requested by the digital cinema server based on the specified encoding method and the content information, and outputs the information to the digital cinema server.
[0052]
Upon receiving the information on the position of the content file, the control unit 41 of the digital cinema server 4 for A-compression accesses the content storage server 1 based on the received information. Since the information on the location of the content file indicates a file “content1.mpeg” in the “mpeg2” folder, the control unit 41 determines “content1.mpeg” in the “mpeg2” folder in the disk array 14 of the content storage server 1. Access the file named
[0053]
The control unit 41 reads the content file “content 1”. The control unit 41 causes the A-compression compatible decoder 42 to perform a decoding process on the distributed content file “content1.mpeg”, and generates “content 1” which is an expanded movie content.
[0054]
The control unit 41 outputs “content 1”, which is the decompressed movie content, to the disk array 45 for storage. The control unit 41 reads out “contents 1” stored in the disk array 45 and outputs the “contents 1” to the movie playback device when playing a movie. The movie playback device plays “content 1”.
[0055]
Here, when the data transmission speed of the broadband network 3 is sufficiently high and the output speed of the content file is sufficiently high because the number of digital cinema servers accessing the content storage server 1 simultaneously is small, the control is performed. The unit 41 may perform the decoding process while receiving the file “content1.mpeg” and display it without receiving the expanded “content 1” in the disk array 45. However, if the expanded "contents 1" is stored in the disk array 45 and read out at the time of the screening, the risk that the screening will be interrupted if the connection with the contents file storage means 1 is disconnected for any reason. Can be avoided.
[0056]
If the data transmission speed of the broadband network 3 and the output speed of the content file of the content storage server 1 are sufficiently high, the content storage server 1 may store the uncoded content as it is. In that case, an uncompressed digital cinema server (at the same level as the “A” or “B” method) receives the uncoded content and stores it in the disk array without performing decoding processing. Or show.
[0057]
Embodiment 2 FIG.
The multimedia-compatible computer 2 may include an authentication unit 36 connected to the BUS 34 and having an authentication function, and the authentication unit 36 may be configured to include an encryption function. The authentication unit 36 outputs decryption information (for example, a decryption key) in response to a decryption request from each digital cinema server.
[0058]
In the movie content distribution management server, encryption means for encrypting the movie content, and when the digital cinema server requests the storage location of the movie content in the content storage server, authenticates the digital cinema server, and encrypts the encrypted movie content. The authentication unit that supplies the information for decryption to the authenticated digital cinema server is realized by the authentication unit 36.
[0059]
In this embodiment, the operation until the input content is stored in the content storage server 1 is different from that of the first embodiment in that, when the content is input in the multimedia-compatible computer 2, the authentication unit 36 is that after the content is encrypted, the A-compression-compatible encoder 321 performs encoding for compressing the data amount. The other operations are the same as those of the first embodiment, and the description is omitted.
[0060]
A description will be given of the operation of this embodiment, which differs from the first embodiment, in the operation from the reception of a content file by each digital cinema server to the presentation of a movie.
[0061]
When the A-compression-compatible digital cinema server 4 receives the encrypted content file “content 1” compressed by the “A” method, the control unit 41 first sends the content file “content 1” to the A-compression compatible decoder 42. Is decrypted to generate expanded content “content 1”. At this stage, the expanded “content 1” has been encrypted.
[0062]
Further, the control unit 41 accesses the authentication unit 36 of the multimedia-compatible computer 2 to extract the decryption information. At this time, the authentication unit 36 performs an authentication process. That is, it is determined whether or not the A-compression-compatible digital cinema server 4 has the authority to receive “content 1”. If the A-compression compatible digital cinema server 4 has the authority to receive the “content 1”, the decryption information is transmitted to the A-compression compatible digital cinema server 4. Use conditions such as the number of times the content is reproduced and the reproducible period may be set in the decryption information.
[0063]
The control unit 41 decrypts the content “content 1” using the decryption information. Then, the encryption is released, and the content “content 1” can be screened, and the digital cinema server 4 supporting A compression can screen the movie.
[0064]
In each of the above embodiments, in the movie content distribution management system, the content storage server 1 stores movie content encoded by various encoding methods, and the multimedia-compatible computer 2 responds to the request of the digital cinema server. In addition, since the digital cinema server is configured to supply the movie content encoded by the encoding method that can be handled by the digital cinema server to the digital cinema server, the digital cinema server has a decoding function using at least one type of encoding method. You only need to have it. Therefore, costs for handling digital cinema can be reduced.
[0065]
In each of the above embodiments, the multimedia-compatible computer 2 encodes unencoded movie content and stores the encoded movie content in the content storage server 1. Means may be stored in the content storage server 1 by means. For example, the encoded movie content may be directly input to the content storage server 1. Also, the content storage server 1, the multimedia-compatible computer 2, and each digital cinema server are connected by the broadband network 3, but the content storage server 1 and the multimedia-compatible computer 2 communicate with each other via a LAN or a dedicated line. It may be performed. Further, the multimedia-compatible computer 2 and each digital cinema server may communicate with each other via a LAN or a dedicated line.
[0066]
