Present system for numeral copyright management technological overview is as follows: the DRM system is the content unique identification of a uniqueness of each legal digital content distribution, and set up content unique with corresponding relations service provider, copyright rule, contents attribute etc.Before the DRM system allows that supporting downloading and playing rouses oneself; shielded content has embedded the content unique identification of self; so that the DRM system is by detecting this content unique identification; and correspond to copyright rule, contents attribute and ISP's information, thereby realize mandate to digital content.Foregoing uniqueness sign exists with the DRM content format (DCF) of digital watermarking Open Mobile Alliance regulation usually, wherein, digital watermarking is meant with signal processing method slips into hidden mark in digitized multi-medium data, this mark has only detector, the reader by special use to extract, in the content unique identification of DCF form then is included in the medium type of version number, unencrypted digital content, the first-class information of metadata information except that digital content object according to the form of Open Mobile Alliance regulation.
The fundamental starting point of above-mentioned technical system is; user charges just can obtain the part authority of downloading and playing copy propagation; the present balance of the constituting body of technical system service provider; copyright owner's distribution of income relation; application popularization along with network; multimedia problem of piracy becomes increasingly conspicuous; protect and crack because undying game is being carried out in the existence of interests; all these are round paying and freely obtaining and carry out; Motion Picture Association of America's investigation shows that 2005 are only the Hollywood film city has just lost 6,100,000,000 dollars.
The cost that numeral property right management protection produces rises and causes interests to flow to following link: 1, property right protection mechanism 2, service provider, 3, channel; 4, video disc 5, packing link 6, wholesale 7, retail link; 8, adorn auspicious design 9, storage 10, transportation 11, advertisement 12, sales promotion ... the real income that the copyright owner obtained is had a greatly reduced quality; the generation of the consumption that the property right protection of paying will limit undoubtedly greatly; simultaneously; copy right piracy has at a low price occupied a part of accurate consumption market
The present invention proposes a kind of digital property right protection method that shifts the paying object; promptly; paying side is the advertisement user; the multimedia file inserting advertisement; system provide digital document download, play, duplicate, the Collection and analysis of information data such as imprinting, distribution; according to the download of digital multimedia, play, duplicate, imprinting, distributing data, set up payment rule, high user pays the copyright owner by advertisement.Essence of the present invention is advertisement plate change power, has become advertiser's payment copyright fee by original broadcast user by the payment copyright fee of paying, and plays the user by the view for free multimedia video, receives advertising message and exchanges video playback power for.
Summary of the invention
First aspect present invention proposes a kind of method for video coding.
According to the present invention, recompile mandate video file, wherein will embed the data packet stream of following five aspects, it at first is the embedding of authorized agreement, in the encryption lock mode, be used for the feedback permission of authorizing multimedia file process behavioral data, its objective is that obtaining the user plays for sending feedback user, distribution and secondary are play the permission of behavioral data, otherwise, such transmission feedback is regarded as malicious acts such as spyware and even backdoor programs usually, authorization will with the agreement of agreement whether like this form present, if the user disagrees with the clause of agreement, file promptly locks, and cancellation is play, the authorization key that can be understood as this moment promptly is to the following of authorized agreement, and cipher key technique belongs to the technique known category.
According to the present invention, also will embed the copyright identification watermark, different from the past is, by embedding the copyright identification strings, the download that is used to search for p2p node file is if but intranodal has other similar video files but not this copyright identification watermark among the present invention, the search end will not present, thereby shielded the down operation behavior, its purpose is to prevent that of the same name, similar unauthorized file is downloaded use, and this is provided with needs point-to-point downloading to install the watermark recognition device additional and finished jointly.
According to the present invention, it is necessary embedding the advance notice video, embed the TV guide video unit by recompile, synopsis video preview before being used to download, this is because for large-scale high sharpness video program, under the current network facility condition, download hundreds of million and even will consume for a long time with the file of G opinion, if the user does not have prior preview file advance notice, downloading back discovery content dislikes, all a kind of waste for user time and broadband resource, based on the favorable user experience angle, the present invention is provided with this function.Embed file and can be shifted to an earlier date downloading and playing separately, the continuation download needs to start all files and downloads.
Similarly, embed the preview picture and can be used as replenishing of above prior advance notice function, embed the TV guide picture element unit cell by recompile, the synopsis preview picture before being used to download based on mentioned above principle; Embed file and can be shifted to an earlier date downloading and playing separately.
According to the present invention, it is most important link that copyright purchaser that is advertisement publishers' advertisement video embeds multimedia file, the embedding of advertisement video should be at least more than three sections, and time point is not fixed, optimal selection is to embed advertisement video according to the program plot and content, and such advertisement video length is longer than television advertising usually.
So far multimedia file producing finishes.
Second aspect present invention proposes a kind of method of downloading the authorizing multimedia file by point-to-point search.
The search of point-to-point download in the past is mostly just according to the title of file, uncontrollable for the deceptive practices of renaming like this, the more important thing is for pirate multimedia programming powerlessly especially, this also is the indicted repeatedly major reason of point-to-point download service mechanism.The present invention changes these present situations by following measure: at first, by watermark identification, client is searched the multimedia file of this mandate search in network at the search end; By the identification title, be used for comparison identification watermark inner multimedia file name, select for download person; By transferring the cookies fileinfo, be used to search user side and be transferred to authorizing multimedia file on other memories; Screen the hunting zone by above three kinds of modes, the download and the distribution of protection authorizing multimedia file.
