Description
1, technical field
The present invention is a video grogramme issuing system based on the internet.This system can carry out high efficiency compression to video frequency program, the video frequency program after the compression is encrypted, and the data of software decoder, decryption software and video frequency program are broken into a file bag.Use the internet as distribution channel and transmission medium, video frequency program and decoder high efficiency, be delivered on the user terminal cheaply.The user receives after video frequency program and the decoder, can play the video frequency program that embeds wherein in the operation decoder.
2, background technology
The present invention with following 3 kinds of technology as the basis:
(1) technique of internet
Internet is that the world is maximum computer interconnection network, is the general name of thousands of information resources.These resources are distributed on millions of the computers all over the world online with the form of e-file; Developed many application systems on the Internet, used for the user on the Access Network, online user is exchange message easily, shared resource.Internet also can think the network that diverse network is formed, and it is to use the data network collective of ICP/IP protocol (transmission control protocol/IP(Internet Protocol)) mutual communication.Internet is a stepless network, is not had by certain individual or entity specially and controls, and everybody can participate in.
Internet originates from the U.S., has been communicated with a global supercomputer internet now.Internet is most active fields and the most popular topic in recent years.And growth momentum is swift and violent.Become a kind of irresistible trend.According to statistics, by 2005, Internet will connect nearly 1,000 ten thousand networks, and nearly 500,000,000 computers have the user more than 1,000,000,000.
Why Internet obtains so swift and violent development, mainly gives the credit to following characteristics:
(1) it is a global computer internet.
(2) it is a huge information material.
(3) the most important thing is that Internet is a big family, have several ten million people to participate in, enjoying the human wealth of oneself creating (being resource) jointly.
Particularly in recent years, since the continuous improvement of internet hardware and software, the fast lifting of information transfer rate, it is more convenient that the user feels, and the rate of information throughput is faster.Simultaneously, because the raising of the network bandwidth makes the original video program because data volume is too big, can't be possible by becoming of Internet transmission.
(2) compression of video frequency program and playback technology
What video frequency program comprised contains much information, and how efficient and harmless compression and playback is a technology that developed rapidly in recent years.Along with development of electronic technology and video frequency program transmit the urgency that requires, the data compression and the playback algorithm of multiple suitable video frequency program appearred in recent years, as MPEG2, MPEG4, JPEG, WMA, Divx or the like.But, in the compression and playback technology of video frequency program, still lack and can take into account big compression ratio, high picture quality, the algorithm of playback fast at present.
(3) software encryption technique
The basic process of data encryption is exactly to being that expressly file or data are handled by certain algorithm originally; make it become unreadable one section code; be commonly referred to " ciphertext "; make it after the corresponding key of input, just can demonstrate original content, reach the purpose that protected data is not stolen, read by juridical-person by such approach.The inverse process of this process is deciphering, is about to the process that this coded message is converted into its original data.By the access times of control key, just can reach the purpose that the control user used or read specified file.
Encryption technology is divided into two big classes usually: " symmetrical expression " and " asymmetric ".It is exactly that same key is used in encryption and decryption that symmetrical expression is encrypted, usually being referred to as " Session Key " this encryption technology is widely adopted at present, as the des encryption standard that U.S. government adopted is exactly a kind of typical " symmetrical expression " enciphered method, and its Session Key length is 56Bits.Asymmetric is encrypted and is exactly encryption and decryption employed be not same key, two keys are arranged usually, be called " PKI " and " private key ", and their two essential pairings are used, otherwise can not open encrypt file.Here " PKI " be meant and can externally announce, " private key " then can not, can only know by people of holder.Its superiority is with regard to here, because the encryption method of symmetrical expression is if just be difficult to tell the other side key at the transmission over networks encrypt file, no matter how all might do not intercepted.And the encryption method of asymmetric has two keys, and wherein " PKI " be can be disclosed, also just is not afraid of others and knows, as long as passable with the private key of oneself, has so just avoided the transmission security problem of key well when the addressee deciphers.
3, summary of the invention
At present, the pirate phenomenon of movie and video programs is very serious.A large amount of pirated CDs flood market, some area even formed the integration of production, supply and marketing.So movie and video programs are easy to by piracy, the one, because generally with the data mode storage, duplicating and propagate all, present movie and video programs are very easy to; The 2nd, because pirate program needn't be paid the expense of intellectual property, cost is low, and price is low, and certain market and customer group are arranged.Because the existence in the pirate market of movie and video programs, creator's intellectual property can't be effectively protected, and the cost of input is difficult to regain.Cause the creator to lack enthusiasm and initiative, serious restriction the development of cultural industry.Simultaneously, creator and publishing house also need to drop into a large amount of funds and manpower and piracy and struggle.But, get half the result with twice the effort DeGrain often.
In recent years, technique of internet is fast-developing and universal, the transmission speed of network is more and more faster, the compression algorithm efficient of video frequency program is more and more higher, add that the computer terminal is more and more universal, the occupation rate of computer is also more and more higher per capita, and this just makes video frequency program have good basis by the internet distribution.
System of the present invention relies on the internet exactly, based on network, relies on existing hardware foundation, reaches low-cost, the purpose of high efficiency distribution video frequency program.Though pirate video frequency program need not to pay relevant intellectual property fees to the creator,, it remains with CD dish or DVD dish is that media is propagated, and still needs links such as production, printing, transportation, manpower distribution, and certain cost is also arranged.With the distribution of the video frequency program of piracy relatively, by internet distribution video frequency program owing to do not need media as carrier, so, saved production, printing, transportation, do not need the sales force of terminal StoreFront and StoreFront yet.So cost is lower than piracy certainly.Simultaneously, because the internet spread scope is wider, the user can obtain relevant information faster, obtain needed video frequency program easily, and owing to be legal program, the quality that plays back program has sufficient assurance, thus troclia purpose sales volume greatly.Because the increase of sales volume, creator and distributing and releasing corporation are ready to be sold to unique user with lower price, thereby can make the user buy video frequency program with lower cost.Like this, both guaranteed that the creator can obtain higher repayment, excited creator's enthusiasm.Simultaneously, the advantage that original piracy is had exhausts, and makes piracy profitless, has hit piracy greatly, even can limit and restrict pirate development fully.
But the problem that network distribution movie and video programs maximum is provided is how to guarantee that program that certain user buys only limits to oneself and watches, and can not be put into the network diffusion of getting on.Otherwise, as long as sell portion, just may be by unconfined copy, even be put into the network propagation of getting on.So though U.S. APPLE company has started selling legal music program on network, movie and video programs but can not be passed through the Internet sale always.
In order to address the above problem, the present invention mainly starts with from following 3 aspects:
1) video frequency program that sends to the user is through a high proportion of compression, and it is faster that data are transmitted.
2) video data file is embedded in decoding software and the decryption software, breaks into a bag, send to the user in the lump.Because program and decryption software and data file bundle, the user can't only propagate the data file of radio frequency program by the mode of copy on the one hand.Copying or propagate must be together with decoding software and decryption software.And in decoding and decryption software, we have added the function of statistics user access times.Only in the number of times of regulation, decoding software and decryption software just can operate as normal.The user on the other hand, plays, and encrypts, so can not separate the three through cryptographic algorithm because the data of video frequency program, player (decoder) and decryption software mix to be packaged in together.Like this, can guarantee three's safety of data.The 3rd, publisher can prevent that the user from decoding by continuous change decoding software and decryption software.
3) in decoding software that sends to the user and data file, limited user's broadcasting time.In case the user reaches the broadcasting time of regulation, player destroys from the data file of being about to wherein, makes the broadcast that the user can not be unlimited, thus the meaning that has lost diffusion or propagated.Even other users obtain this file, also can only in the number of times of regulation, play.If the buyer has play the number of times of enough regulations, so, the file that he blazes abroad will be incomplete.
