Description

一种数字媒体内容发布方法和系统 A digital media content distribution method and system

技术领域 FIELD

[0001] 本发明涉及数字媒体技术领域,更具体地,涉及一种数字媒体内容发布方法和系统。 [0001] The present invention relates to the field of digital media technology, and more particularly, relates to a digital media content distribution method and system.

背景技术 Background technique

[0002] 现有的数字媒体内容发布系统已经使用了DRM (Digital Rights Management,数字版权管理)来保护数字化内容的版权,从技术上防止对数字化内容的非法复制和无限制使用。 [0002] existing digital media content distribution system has been used for copyright DRM (Digital Rights Management, DRM) to protect digital content against illegal copying of digital content and unlimited use of the technology. 这里的数字媒体内容可以是音频、视频、电子读物、游戏、软件等数字化产品。 Here's digital media content can be audio, video, e-books, games, software and other digital products.

[0003] 在使用DRM的数字媒体内容发布系统中,一个必经的步骤是要对数字媒体内容进行加密操作。 [0003] In the digital media content distribution system used in the DRM, a necessary step is to encrypt the digital media content operation. 一种现有的数字媒体内容发布系统可以对数字媒体内容进行两次加密操作,一次是对数字媒体内容本身进行内容加密,另一次是针对该内容所属的产品类型进行产品加密,这可以满足一些数字媒体提供商进行灵活的内容发布的需求。 One existing digital media content distribution system for digital media content can be encrypted twice operation, once the digital media content itself, content encryption, another encryption product is for the product type of the content belongs, to meet some of this digital media providers demand flexible content posted.

[0004]图1示出了这种现有的数字媒体内容发布系统的工作流程图。 [0004] FIG. 1 shows a flow chart of such a conventional digital media content distribution system. 如图1所示,在步骤101中,首先对要发布的媒体内容进行打包。 As shown in FIG. 1, at step 101, first to publish media content package. 在步骤102中,对打包后的内容进行加密,其包括同步进行的内容加密和产品加密。 In step 102, the content of the package is encrypted, including the encrypted content encryption and product simultaneously. 在步骤103中,将两次加密后的内容编入编排单,并根据编排单进行各媒体内容的发布。 In step 103, the double-encrypted content incorporated into a single arrangement, and publish the media content in accordance with a single arrangement.

[0005] 在该数字媒体内容发布系统中,对媒体内容进行内容加密和产品加密是在同一个步骤102中同步完成的,而内容加密是一个相对比较耗时的过程。 [0005] In this distribution system of digital media content, media content and the encrypted content encryption products are the same in step 102 of synchronization is complete, and the encrypted content is a relatively time consuming process. 因此,对于该数字媒体内容发布系统的操作员来说,其可能在打包之后需要在步骤102中等待较长的时间才能进行下一步的发布操作,这会严重地延长整个发布流程所用时间。 Therefore, for the digital media content distribution system operator, its might need to wait in step 102 a long time to carry out the next release operation after packaging, which can seriously lengthen the time spent entire publishing process. 而且,按照该数字媒体内容发布系统的工作流程,如果在多个产品类型中含有同一个媒体内容,该同一个内容实际上要分别进行对应的多次内容加密,这也会严重地浪费系统资源和人力资源。 Moreover, according to the workflow of the digital media content publishing system, if it contains the same media content across multiple product types, in fact, the same content to multiple content encryption corresponding respectively, which also seriously wasting system resources and human resources.

附图说明 BRIEF DESCRIPTION

[0026]图1是一种现有的数字媒体内容发布系统的工作流程图; [0026] FIG. 1 is a flowchart of a conventional digital media content distribution system;

[0027]图2是按照本发明的数字媒体内容发布系统的一个实施例的结构示意图。 [0027] FIG. 2 is a schematic structural diagram of an embodiment of the system according to the publisher's digital media content according to the present invention.

具体实施方式 Detailed ways

[0028] 下面结合附图和具体实施方式对本发明进一步详细说明。 [0028] The present invention will be described in further detail in conjunction with accompanying drawings and specific embodiments.

[0029] 如图2所示,该数字媒体内容发布系统200可以包括内容加密单元210,打包单元220,产品加密单元230和发布单元240。 [0029] As shown in FIG 2, the digital media content distribution system 200 may include a content encryption unit 210, packetizing unit 220, the encryption unit 230 and the product issuing unit 240.

[0030] 进入该数字媒体内容发布系统200的数字媒体内容的文件通常包括主文件401和附属文件402两类文件。 [0030] access to the digital media content distribution system of digital media content file 200 generally includes a main file 401 and auxiliary file 402 file types. 主文件401通常是指数字媒体内容中含有主要信息的视频文件、音频文件或其它类型的文件。 Master file 401 generally refers to digital media content file containing the main video information, audio files, or other types of files. 附属文件402通常是指数字媒体内容中含有附属信息的文件,如片花文件、海报文件、字幕文件或含有导演、演员、剧情简介等描述信息的文件。 Affiliated file 402 usually refers to digital media content file contains ancillary information, such as files trailers, posters file, or caption file contains a director, actor, Synopsis and other profile information. 需要进行内容加密的文件通常是主文件401。 File needs to be encrypted is usually the main content file 401.

[0031] 可以由内容加密单元210对进入该系统200的主文件401以及可选的其它需要加密的文件进行内容加密操作,以获得对应的内容加密文件251。 [0031] The system may enter the master file 200 401 and other optional file needs to be encrypted content encrypted by the content encryption unit 210 to obtain a content corresponding to encrypted file 251. 该内容加密文件251可以存储在由数据库单元250提供的数据库中。 The encrypted content file 251 may be stored in a database provided by the database unit 250. 在其它实施例中,该内容加密文件251也可以存储在任何合适的指定位置。 In other embodiments, the encrypted content file 251 may be stored in any suitable location specified. 需要注意的是,在这里,内容加密单元210可以连续地对多个内容的多个主文件401进行内容加密,而获得多个内容加密文件251,而无需等待在下文将要描述的对一个数字媒体内容的打包或产品加密操作之后再进行对下一个数字媒体内容的内容加密操作。 Note that, here, the content encryption unit 210 may continuously for a plurality of files a plurality of main content encryption content 401, the plurality of content encrypted files 251, without waiting for the one digital media will be described hereinafter then the next operation on a content encryption of digital media content after the encryption operation or product package contents. 该内容加密单元210可以通过调用现有的数字媒体内容发布系统中的DRM的内容加密模块来实现。 The content encryption unit 210 may be implemented in a DRM system publish content encryption module by calling the existing digital media content.

[0032] 打包单元220可以从该数据库中或者其它的指定位置读取与一个数字媒体内容对应的的内容加密文件251,将其与对应的附属文件402 —起进行文件打包,以获得一个数据包261。 [0032] The packing unit 220 may further specify the position read from the database or to a digital media content corresponding to the content encrypted files 251, a file with the corresponding subsidiary 402-- from package files, to obtain a packet 261. 该数据包261可以是一种预定的数据结构,如预定的目录结构,其包含与该数字媒体内容对应的内容加密文件251和附属文件402。 The data packet 261 may be a predetermined data structure, such as a predetermined directory structure which contains the corresponding media content to the digital content 251 encrypted files and auxiliary files 402.

[0033] 产品加密单元230可以根据该数据包261所属的产品类型对其进行产品加密,以获得对应的加密数据包271。 [0033] Product Product Type encryption unit 230 according to the packet 261 belongs to encrypt its products, to obtain a corresponding encrypted data packet 271. 产品类型可以根据数字媒体提供商的运营需要而预先设定,例如可以是包月产品、定制产品、点播产品,等等。 Product type according to operational needs of digital media provider previously set, for example, can be a monthly subscription products, customized products, product demand, and so on. 该产品加密单元230可以通过调用现有的数字媒体内容发布系统中的DRM的产品加密模块来实现。 The product encryption unit 230 may be implemented in a DRM system publishing products encryption module by calling the existing digital media content. 在一个实施例中,该加密数据包271实际上是在数据包261中加入一个由产品加密操作产生的密钥文件,如.DRM文件。 In one embodiment, data packet 271 the encrypted key file is actually added to a product produced by the cryptographic operations, such as data packet .DRM file 261.

[0034] 在一些情况中,同一个数字媒体内容可能会被放入到不同的产品中,换句话中,该数字媒体内容可以属于多个不同产品类型。 [0034] In some cases, the same digital media content may be put into different products, in other words, the digital media content may belong to a plurality of different product types. 此时,当打包单元220和产品加密单元230对该数字媒体内容中的文件进行打包和产品加密操作时,无需对同一主文件401进行多次内容加密操作,而是在打包单元220中可以重复使用同一个已经加密的内容加密文件251,或者可以在产品加密单元230中重复使用同一个包含对应的内容加密文件251的数据包261,以获得对应不同产品类型的多个加密数据包271。 At this time, when the packed product unit 220 and the encryption unit 230 of the digital media content files packaged products and cryptographic operations on the same master file 401 without multiple content encryption operation, but may be repeated in the packing unit 220 using the same encrypted content already encrypted file 251, or may be used the same data packet 261 contains the contents of the encrypted file 251 corresponding to the product of the encryption unit 230, to obtain a corresponding plurality of different types of products 271 encrypted packets.

[0035] 发布单元240可以将加密数据包271通过内容传输投递系统在预定的时间发布给终端用户。 [0035] The issuing unit 240 may release the encrypted data packet 271 to the end user in a predetermined transmission time by the content delivery system.

[0036] 由于由内容加密单元210对主文件401所进行的内容加密操作是一个相对比较耗时的过程。 [0036] Since the contents of the encryption operation performed by the content encryption unit 210 of the main file 401 is a relatively time consuming process. 因此,对于该数字媒体内容发布系统200的操作人员来说,他可以在打包、产品加密或发布操作的空闲期利用该内容加密单元210预先对进入该系统200的主文件401进行内容加密操作。 Thus, for the operator of the digital media content distribution system 200, he may be packaged, the product release encryption or idle operation of the content encryption unit 210 using advance into the main file system 200 of the encryption content 401. 进一步,可以对进入该系统200的主文件401成批地进行内容加密操作。 Further, the content encryption operation may be performed on the file system 200 into the main 401 batches. 这样,当需要发布一数字媒体内容时,可以直接使用已经加密好的内容加密文件251进行打包、产品加密和发布操作,从而大大提供工作效率。 Thus, when the need to publish a digital media content can be directly used to package and distribute encryption products operations have good content encrypted files encrypted 251, thus providing work efficiency greatly. 这意味着对多个数字媒体内容的主文件所进行的内容加密操作可以是在对其中任一内容进行的产品加密操作之前进行的,这明显区别于在背景技术部分所描述现有的工作流程。 This means that the contents of the master file encryption operation on a plurality of digital media content may be performed before the product is carried out on any of the encryption operation content, which is obviously different from that described in the Background section existing workflow .

[0037]另外,该数字媒体内容发布系统200适合于由分布式系统来实现,这样,可以将工作内容比较单一但是比较耗时的内容加密单元210以及可选的数据库单元250独立设置在分布式系统的一个节点上,而其它单元设置在其它节点上。 [0037] Further, the digital media content distribution system adapted implemented by a distributed system, so that work can be compared to the contents of a single time-consuming but the content encryption unit 210 and the optional database unit 250 is provided independently distributed 200 a node of the system, while the other unit is disposed at the other nodes. 这样,可以由不同的操作人员分别操作各节点,从而有利于集中地对进入该系统200的各个内容的主文件401进行内容加密。 Thus, can be operated by different operators are each node, thereby facilitating the system collectively on the master file into the contents of the respective content 200 encrypted 401. 并且,在内容加密单元210进行工作的同时,可以在其它节点上对已经完成的内容加密文件251及其附属文件402进行打包、产品加密或发布等操作。 And, while the content encryption unit 210 to operate may be made and other packaged product or release operation of the encrypted contents of the encrypted file has been completed and its appendices 251 402 on other nodes.

[0038] 虽然在上文中已经结合图2的数字媒体内容发布系统200描述了一种按照本发明的数字媒体内容发布方法。 [0038] Although in the above in conjunction with FIG. 2 has digital media content distribution system 200 according to Post describes a digital media content according to the present invention method. 但是应当理解,本发明的数字媒体内容发布方法可以不依赖于图2所示的系统来实现。 It should be understood that the digital media content distribution method of the present invention may not rely on the system shown in Figure 2 is achieved. 在按照本发明的数字媒体内容发布方法的一个实施例中,可以对于每一数字媒体内容进行内容加密步骤、打包步骤、产品加密步骤和发布步骤。 In one embodiment of the distribution method according to the present invention, the digital media content can be made for each digital media contents encrypting step, the step of packaging, the product release step and encrypting step. 在内容加密步骤中可以对数字媒体内容中的预定文件例如主文件进行内容加密,获得对应的内容加密文件。 Example, the main content may be a file of a predetermined file encrypted digital media content in the content encryption step, to obtain a corresponding content encrypted files. 在该内容加密步骤中,可以将所述内容加密文件存储在一个数据库中。 In this step, content encryption, the content encrypted files may be stored in a database. 在打包步骤可以对数字媒体内容进行文件打包,获得对应的数据包,该数据包中包括在内容加密步骤中获得的内容加密文件,并可以从所述数据库中调用该内容加密文件。 In the packing step may be performed on digital media content files are packaged to obtain a corresponding data packet, the data file including encrypted content obtained in the content package encrypting step, encrypted contents and can be called from the database file. 随后,可以根据编单任务对定期投递计划进行数据包编排,此时则可以确定数字媒体内容所属的产品类型。 Subsequently, data packets can be organized on a regular delivery program compiled according to a single task, then you can determine the product type of digital media content belongs. 之后,在产品加密步骤中可以对该数据包根据其所属的产品类型进行产品加密,获得对应的加密数据包。 Thereafter, in step encrypted product may be encrypted according to the product type of product which the data packet belongs to, to obtain the corresponding encrypted data packet. 在一个实施例中,产品加密步骤是在数据包中加入由产品加密操作生成的密钥文件,以生成加密数据包。 In one embodiment, the encryption step is added to the product generated by the product file encryption key in the data packet, to generate an encrypted data packet. 最后,在发布步骤中可以将加密数据包发布给终端用户。 Finally, the release step, the encrypted data packets may be distributed to end users. 很明显,相比于现有技术,本发明的内容加密步骤和产品加密步骤是分别设置在打包操作前后两个步骤中进行的,并且,多个数字媒体内容对应的内容加密步骤可以在其中任一数字媒体内容对应的产品加密步骤之前进行。 Obviously, compared with the prior art, the step of encrypting the content encryption step and the product of the present invention is carried out in two steps are provided before and after the packaging operations, and the content encryption step corresponding to a plurality of digital media content may be in either product prior to the step of encrypting a corresponding digital media content.

[0039] 在该数字媒体内容发布方法中,对于属于多个不同产品类型的同一数字媒体内容,可以在打包步骤中复用与同一数字媒体内容对应的同一个内容加密文件,或者,可以在产品加密步骤中复用与同一数字媒体内容对应的同一个数据包。 [0039] In the digital media content distribution method, for the same digital media content belongs to a plurality of different types of products, the same content can be multiplexed with the encrypted file corresponding to the same digital media content in the packaging step or, alternatively, the product may be encrypting step a multiplexing the same packet with the same digital media content corresponds.

[0040] 虽然已经按照上述实施例描述了本发明,但是应当理解,在本发明的权利要求的范围内,本领域技术人员可以对上述实施例进行任何变化。 [0040] Although the present invention has been described in the above embodiments, it should be understood that, within the scope of the appended claims, those skilled in the art can make any variations of the above embodiments.
