Description
Technical field
The present invention relates to the digital copyright protecting in multimedia field, the digital literary property protection method of the VOD system of especially playing Karaoka and management system thereof.
Background technology
Along with the fast development of Internet technology and multimedia technology, a large amount of digital contents is propagated in the consumer by network, CD or alternate manner.Because the copy of digital content and propagation are very convenient, how to prevent that the abuses such as wide-scale distribution of pirate digital content from just becoming a difficult problem of puzzlement digital content provider and operator.In the prior art, general digital copyright management technology and architecture mainly comprise as the lower part:
1) encrypt digital content: digital content is encrypted and packed, use a key to be locked.
2) packaged content distribution: the file that will pack sends to the consumer by forms such as network, CDs.
3) obtaining of licence: in order to play the digital document of a packing, the consumer must at first obtain the licence that can decipher packaging file.
4) play numeral (medium) file: for the playing digital medium file, player of supporting digital copyright management of consumer wants is according to being included in the rule in the licence and authorizing playing media file.Licence can comprise different mandates, as the date and time that begins to play, lasting time, broadcasting time etc.
At present, be network digital content release and copy-right protection method based on main, the most popular digital literary property protection method of above-mentioned digital copyright management technology, its principal mode is as follows:
1) towards the Internet network user's copyright protection mode
1. the download or the online request of digital content are provided for the network user by network: the file of soon having encrypted is put on the WEB website for the network user and downloads, or is the online broadcast of the network user by media server.
2. the network user obtains licence by network: at first directly obtain the broadcast licence of this document during user's playing media file by the Internet network, and could the normal play file.
2) towards the copyright management strategy of individual digit media file
1. encryption policy one to one: the strategy of a corresponding a kind of encryption method of digital media file.
2. licence provides and acquisition strategy one to one: for a licence is provided in each download or each online broadcast of each enciphered digital media file.
3) copy-right protection method of limit time broadcast in limited time,
1. according to the characteristics of network user consumption, the license type that provides for the user comprises the type of the type that limits reproduction time, restriction broadcasting time and not only but also the type time play of limit in limited time, to guarantee legal digital content, avoid digital document to propagate arbitrarily on the net not by piracy.
The above-mentioned form of network digital content release and copy-right protection method shows that it only is applicable to the network issuing service of digital content and the network user's personal consumption form.And in the face of the Karaoke VOD system consumption pattern, above-mentioned existing digital literary property protection method then can't be realized.
At first, the business of karaoke halls is to move under the LAN environment that is independent of the relative closure outside the Internet net.The consumer of singing-hall is the order program service that obtains Kara OK songs by the internal lan network, rather than directly obtains service from content operator by Internet.So, be difficult to effectively support the normal operation of this LAN business towards the Internet network user's existing copyright protection mode.
