Description
Technical field
The present invention relates to the television network broadcast technology, relate in particular to a kind of system and method based on the broadcast channel content index transmission.
Background technology
Along with Internet video becomes the maximum driving force of data communication, U.S. Cisco System Co. estimates that 2007 to 2012, the Global Internet flow will increase by five times.Internet video account for the Internet total flow ratio will from 2005 5% be increased to 30% of the end of this year, will further increase to 50% by 2012.According to estimates, every month flow of Global Internet is 7EB (7,000,000,000 GB) at present, is equivalent to the capacity of 2,000,000,000 DVD.To reach 44EB to these data in 2012.Estimate that Internet video will be above the proportion of file-sharing in total flow in two years.What the big prosperity of being not only knowledge and information that so abundant information is brought to people also was simultaneously people for magnanimity information is vast and hazy.The gopher easily that Google, Yahoo and Baidu bring to people is not wanted but the result that they search out is us greatly, and people still need to seek one by one from the result that they provide.The WEB search of today can be found unnumbered wide of the mark " result " usually, needs a large amount of manual filtration work.Present WEB retrieval mainly is to rely on keyword that content title is searched for, rather than to its content itself.Title is difficult to comprehensively its content be disclosed.
The transmission mode of the Internet is a kind of transmission of point-to-point, and guarantees that data can be transferred to destination address from source address accurately, so have only source address and destination address information in the IP pack arrangement.Without any the content information of institute's load, computer can't be discerned its content.No matter be hasty and careless rough draft, no matter still exquisite works are business information or academic content, which kind of culture and language no matter, and network is all made no exception to them.Caused the identical content can the meaningless heavy transmission of covering of Bo between identical node like this, the waste network bandwidth.
Supervision at illegal contents on the Internet is a difficult point always.Being not only because to upload the transmission information amount very big in the Internet, also is simultaneously in default of the fast and accurate method of identification.Packet-switch technology has disassembled source contents into a large amount of small data packets, and these small data packets arrive destination address by different routes.The transmission content that has caused each packet to carry like this is incomplete, also is difficult to capture all relevant small data packets simultaneously.Even captured the IP packet of some illegal contents, whether what can't analyze also that IP bag carries is illegal content, also can't determine be who in transmission, what agreement it utilizes propagating.This propagates just for the Control Network invalid information, has caused very big difficulty.Especially in recent years P2P business in the Internet is flourish, its flow has accounted for more than 60% of network total flow, in so a large amount of P2P flows, be flooded with harmful informations such as reaction, pornographic, violence, wide, the propagation velocity of its spread scope be that traditional the Internet is incomparable soon, it is extremely urgent that it is strengthened supervision.
In the internet information transmission course, lack informant and information category authentication mechanism, be to cause the unsafe major reason in the Internet.The user can't discern its source of receiving information and data type, more can't interpretation receives whether safety of data, and many lawless persons utilize this point, and illegal program is pretended to implant custom system, and the userspersonal information is stolen, and seek illicit gain.At present, main to the identification of illegal invasion and virus obtaining on known the intrusion behavior feature and virus characteristic, the network information is compared judgement.And for increasing novel attack pattern and virus, the computer user is difficult in the very first time and is on the defensive.
Index is the process of content being carried out feature extraction and sign guiding, and its purpose is the disclosure feature, is convenient to concentrate similar content, distinguishes different contents, for related content is set up contact.Can improve the management and use rate of resource by index.Index improves the quality of computer search to the retrieval that the retrieval of content is changed into to structural data.
The tradition index is based on keyword, promptly extracts keyword by word frequency statistics, according to keyword document is carried out index then.This mode has been widely used in various commercial search engine.Mentioned way based on keyword is to be based upon on the basis of some hypothesis, do not have ambiguity etc. as independently of one another between the keyword, keyword, these hypothesis make processing procedure simplify greatly, and mentioned way is rested on the logic aspect of the literal similarities and differences of keyword.In the different linguistic context, different implications may be represented in identical keyword, and different keywords also may be expressed with a kind of meaning.Often be not to have no relation between the keyword yet.Having ignored the implication of notion aspect or semantic level based on the index of keyword, is to cause the dissatisfactory key factor of retrieval effectiveness.
