Description
Technical field
The present invention relates to the interactive TV technology of network-oriented, relate in particular to the distribution method and the system of the guidance information of guiding interactive service in the interactive TV.
Background technology
The development modern service industry has become a strategic decision of China.Modern service industry has high technology content, high added value and high-profit characteristics.In recent years, the modern service industry of the global range development climax tide that is accompanied by information technology revolution occurs.Between modern service industry and the informationization is interaction relations: the new and high technology that with the information technology is representative is the support of modern service industry, is the important motive force of modern service industry development; And the development of modern service industry is also leading development of high-tech, is the key areas that modern information technologies are used.
In radio, TV and film industries, the development of digital media technology and Internet technology is promoting one by the deep reform of traditional media to the new media transition.The interactive TV industry is the core of new media industry.In a broad sense, interactive TV comprises that interactive Digital Television, interactive network television (IPTV) and all can realize the television system of interaction function, in these systems, interactive network television (IPTV) relies on broadband IP network to realize carrying, is the developing direction that technology is advanced relatively, market prospects are expected.1999, Britain Video Networks company took the lead in having released in the whole world IPTV business.Before 2004, most carrier sides overweight the test of IPTV, and after 2004, the development of IPTV begins to move towards commercial stage from experimental stage.According to the prediction of the authoritative Strategy Analytics of market research agency, global ip TV number of users will reach more than 8,000,000 in 2006, and the professional income of IPTV will reach 8,000,000,000 dollars; And by 2008, global ip TV total number of users will will reach 15,000,000,000 dollars at least above the professional income of 2,600 ten thousand, IPTV.As seen, a huge emerging consumption market starts rapidly.
Compare with traditional tv, the characteristics of interactive network television are embodied in following aspect: at first, in content production and management, interactive TV extensively adopts digital media technology and computer technology, and the whole life of interactive network television content is all stored, processed and propagate with digital form.The second, on the rating function, different with traditional tv individual event broadcast mode is, interactive network television relies on broadband internet to realize brand-new personalized interactive function, and spectators can send instruction by remote controller, select programme content and broadcast time etc. arbitrarily; The 3rd, on service form, incorporating of information technology and network technology will make interactive network television become a powerful multi-function service platform, and television channel is a traditional tv unique service content, but one of numerous service content of providing of interactive network television platform just.On this platform, spectators can initiatively ask for all kinds of information, can do shopping, seek doctor, friend-making, financing ... in a word, the interactive network television platform almost can carry all service forms on the Internet, and compare with the Internet, the platform that with the TV is core has more vast audient, the popularity of more concentrated user watched behavior and Geng Gao.Can predict, the interactive network television platform will become information tie important between consumers in general and the modern service industry every field in the near future.
In the new media industry development, application service construction is to rely on the basic network, and new content-form and service pattern must rely on high performance network and realize carrying, and therefore, network has become the active demand of interactive network television development in advance.Stem-winding is that the research of Chinese broadband network of future generation and experimental deployment make important progress." high performance wideband information demonstrate net " (being 3TNet) as the great special project of 863 Program, be that China more than 50 tame famous enterprises, R﹠D institution and universities and colleges go through 4 years obtained major scientific and technological achievements of arduous tackling key problem, T bit-level high-speed light that 3TNet is integrated transmission, T bit-level automatic switched transport network and T bit-level dual-stacker router and broadband streaming media, multimedia application back-up environment.3TNet build up and the basis of launching to try out on, in October, 2005, formally build up and begin commercial test operation in Yangtze River Delta some areas based on 3TNet " demonstration of high definition interactive network television "." demonstration of high definition interactive network television " with streaming media service such as live telecast and video request programs as core business, the high bandwidth and the full interaction characteristic that himself possess simultaneously provide network condition for supporting all kinds of interaction multimedia value-added services, and the carrier grade service requirement that can reach high-quality, have QoS to guarantee.3TNet successfully lands and has brought opportunity for the development of interactive TV industry undoubtedly.
At present, lot of domestic and foreign businesses and institutions drops into the research and development of interactive network television applied technical field one after another, and many achievements have dropped into test operation, such as " demonstration of 3TNet high definition interactive network television " mentioned above.The research and development major part of these projects encloses time shift and VOD two big functions are launched.The time that time-shifting function makes the user can freely select to watch program, VOD then provides a great selection of program to select to watch by interest for spectators.Time shift and VOD are the maximum characteristics that interactive network television is different from traditional tv, also are the functions that current televiewer presses for most.Yet follow the realization of time shift and VOD, some realistic problems also come one after another, for example time shift can allow the user enough skip advertisement part in the program, this variation has caused direct influence to the television advertising industrial chain, before new appearance of television advertising marketing model and formation system, therefore the advertising market of traditional media may shrink.As seen, technological innovation must adapt to market discipline, and the development need of interactive TV is sought a suitable track.
Certainly, the operation of interactive network television will be towards the direction evolution of comprehensive service platform.Following interactive network television will be born integrated modern service industry information, drive the important mission of modern service industry development comprehensively.From a long-term perspective, realizing that time shift and VOD only are the first steps of interactive network television development, also is two most basic functions that following interactive network television provides.How to rely on the high-performance wideband network that has built up, develop the valued added applications service towards the modern service industry different field, and find a kind of suitable pattern to push relevent information and service access way, this is the problem that should address present stage.In long-term TV operation practice, find that traditional live telecast channel has the advantages that many, popular, the user watched behaviors of audient are concentrated, and carry out the exploitation of interaction function based on the live telecast channel, foundation is the information promulgating platform of door with the channel and pushes all kinds of information and interactive valued added applications service with this, then is a kind of application model that has development prospect.At present in the broadband network TV domain, at the research and development of this pattern with use as yet that the someone sets foot in.
