Description

A kind of integrated information terminal construction method and device thereof

Technical field

The present invention relates to a kind ofly utilize Computer and Its Application software, existing-quality television machine, make up a kind of integrated information terminal based on computer internet, Television Broadcasting Network and public telecom network system platform resource with the wired or wireless formula multimedia messages R-T unit and the wireless remote controller of computer and existing-quality television machine interfaces, and the flow media playing method that under this terminal is supported, forms.

Background technology

Development along with network technology and software engineering, the multimedia interaction service mode begins to be widely used in aspects such as information on demand, broadcasting or advertisement, the service of member's formula between internet platform and the user terminal, from but the feature of internet multimedia information service is close to the video display field gradually.

On the other hand, traditional radio and television spread to the Internet gradually, have both comprised spreading of movie and television program content, also comprise interconnecting of Internet resources.

Under the trend aspect above-mentioned two, naturally be born and a new field, be called " IPTV (Intemet ProtocolTelevision) ", promptly " follow the TV of Internet protocol ", its essential characteristic is: with traditional movie and television program content transform data storage format and transmission means, so that propagate on computer internet.

1. about the present situation of MMS (Multimedia Message Service)

So-called " multimedia ", be meant the electronic medium that video and audio frequency are synthetic and form with image and characteristics of speech sounds, comprise all kinds of forms in multimedia service field, for example game machine, multimedia communication terminal or the like, here at, be meant online multimedia service, the multimedia on-line service that promptly has public organization on the basis of certain system resource, to provide to masses with certain culture background basis.

1.1. the fundamental mode of internet multimedia content service

Multimedia service content based on the Internet comprises two classes, the one, and the roundup content service that comprises image and literal that utilizes image making software to make, for example recreation, animation, advertisement etc.; The 2nd, traditional broadcast TV program content translation data forms such as video display musical works or news are issued on internet platform, by the user according to self needs and online request.

1.2. the fundamental mode of traditional movie and video programs service

An essential characteristic of tradition movie and video programs is its broadcast nature, and promptly the play content of movie and video programs is by content provider issue or broadcast, and party in request can only determine whether continue to watch or listen to according to programme content passively.The system that is used to send the video display MBMS service comprises cable television network.

1.3. the MMS (Multimedia Message Service) of exclusive communication network

Public's switched telecommunication network (PSTN) mainly is limited to the access and the transmission of multimedia messages for the multimedia service that communication network provided of basic platform, thereby realize the multimedia realtime communication service, itself neither comprises multimedia information source, does not also comprise relevant multimedia equipment resource.

2. about the development trend of network multimedia information service

As mentioned above, the essential characteristic of serving based on the content of multimedia of the Internet is program request as required, and the decision side of particular content is an information consumer; And the essential characteristic of traditional movie and television program content service be subjective broadcasting, and the decision side of particular content is a content supplier, and spectators or audience can only passive ratings or listened to; As for being the multimedia service of main purpose with communication, then be confined to the exchange and the transmission of information substantially.

Development along with network technology and service mode, traditional video display music program has been fused in the Web content service comparatively fully, even the real-time broadcasting of news and on-the-spot entertainment also can online watching have been viewed and admired by the mode of computer internet online request.When the service of this class is main object with huge telecommunications terminal user, then in fact cause computer internet, cable TV toward and telecommunications network fusion gradually each other.

As seen, the Internet, television network and the telecommunications network integration of three networks comprise two aspects:

The one, the fusion of content.When the content of multimedia service changes the user into according to self objective demand and optional point sowing time by simple subjective broadcasting, the service content of multimedia messages will become and contain content widely, no longer be confined to forms such as films and television programs and news broadcast;

The 2nd, the fusion of network.Because the multimedia service feature is tending towards unified, the user object that different networks is drawn a circle to approve is also unified at last.

3. the bottleneck that current multimedia service form merges

3.1. the fundamental characteristics of three macroreticulars

The service that the Internet, television network and telecommunications network provided has nothing in common with each other.

(1) through size expansion and development, computer internet has been obtained significant progress.Yet, as specialized information platform, the development course of computer internet is confined to the information industry field always and relevant industry is expanded or the intelligent Application field, because internet terminal---the non-ordinary populace of complexity of computer operation can be grasped, therefore, although the ICP attempts to provide colourful service to masses in recent years always, the helpless professional person that can only be confined to have computer operation technical ability, most consumption masses are left out, thereby the priority application that causes the Internet today still rests on the specialized basis, basically belong to the instrument platform of more high-quality colony relatively, lack basis of a mass character.

(2) though cable television network has huge bottom common people user group, but its technology rests on the pattern of One-to-All Broadcast for a long time, though realize in the recent period the access of the Internet and make user base comprise different society level colony, but do not possess effective information communication basis basically, make application surface beat very big discount.

(3) though telecommunications network has the Internet resources of global maximum-norm, but be the main business pattern mainly for a long time so that voice communications services to be provided, though finished the access network construction of certain scale and launched data loading service in the recent period, but only rest on simple Internet access service and local data transport service, user level in this respect and Internet user's aspect basically identical, we can say that lack diversified service is telecommunications network bottleneck to be broken through always.

3.2. the bottleneck that three macroreticulars merge

Owing to the Internet, television network and telecommunications network have nothing in common with each other based on the service that different system platforms causes providing, thereby be not only to solve hardware interface between the different network systems platform (for example gateway etc.) and information interface problem in the network integration of today, also will be in the face of following three big bottlenecks:

(1) how to realize the fusion of service content.The service characteristics of three macroreticulars have nothing in common with each other, and computer internet biases toward comprehensive and specialized information and online service thereof; Cable television network biases toward the online broadcasting formula of Streaming Media and plays; Public telecom network then biases toward voice communication.The result of the network integration must cause the mutual unification of the information content, thereby causes the different consumer groups' mutual fusion.This result is obviously against basic market discipline.

(2) how to realize the fusion of terminal form.Corresponding with the different consumer groups, be the different shape of the network terminal.

For cable TV network terminal---television set, century-old video display develop to the user be not only history, also comprise the rich culture intension.Before 40 years since the birth television set, also be not only that the long-range reconstruction of image is so simple, it is a kind of continuity and expansion based on abundant movie and TV culture.

For public telecom network terminal---telecommunication terminal, take place, transmit and be received as feature with real-time information basically, provide the most basic long-range communication means, for a long time based on voice communication.

For the computer internet terminal---a large amount of PC and intelligence system platform and work station, although be widely used, all-embracing, but need special operative skill and professional knowledge, only be confined to the professional person at present and be used as intelligent instrument or platform.

Obviously, in the face of multi-form terminal use, the fusion of three macroreticulars will cause great puzzlement to their relevant consumption.

(3) how to realize the fusion of cultural morphology.People not only are scientific and technological composition wherein or the innovation that is worth showing off for the consumption of products ﹠ services, and are that new service mode must be accustomed to consumer's capital consumption or the continuity trend of nature be combined closely.Under the Market Culture category, so-called consumption habit is actually the corelation behaviour that is produced on the culture base that becomes based on the set custom of a kind of society, in English, and " custom " expression custom and custom, " customer " then represents the consumer.

Because three macroreticulars are based on different cultural layers, in the face of different cultural colonies, therefore, three macroreticulars are the mutual fusion on cultural layer how, and are more much more difficult than the fusion of network itself.

As seen by above-mentioned, if there is not the method for breakthrough innovation to change the restriction of three big bottlenecks, then the fusion of three macroreticulars will be performed practically no function appearance without reality.

3.3. the background of information television machine innovation failure

In the face of the development that information technology is maked rapid progress, information terminal technology application facet also was born and much had the product of innovative significance, wherein with the tool meaning of the process of the birth of information television machine and failure.Trace it to its cause, be understood that the problem of following aspect:

(1) consumer group that faces of television product is an ordinary populace, the consumption feature of this types of populations is amusement or the amenities of life under the simple operations prerequisite, in case TV additional computer network interface function, then Fu Jia complex operations is that this types of populations is difficult to be competent at, correspondingly, the value of Fu Jia network information operating function also just is difficult to embody.

(2) since computer internet is born, its developing steps present suitable high-speed, in current all intelligent equipments, also having only the development as the computer equipment of the supporting terminal of network is to keep synchronously with network technical development, other home appliance development of internet technology paces that all can't closely follow up, thus cause superseded cycle of information household appliances too short and can't obtain popular response.

By above-mentioned example of failing as can be seen about information television machine product, the form of products innovation is except technological innovation itself, also must and Social Culture or the market demand and development trend thereof combine, should fully meet the industry development rule simultaneously, otherwise must face the result of failure.The birth of information television machine meets the technological innovation feature, but and do not meet Social Culture or market demand development trend, simultaneously, this product has been ignored the development speed of Internet technology and to the primary demand of intelligent terminal technical development.
