Detailed description of the invention
Technical scheme is further illustrated below in conjunction with the accompanying drawings with embodiment.
As it is shown in figure 1, the digital communication system of the present invention is for providing information to user terminal, mainly include two transmission networks.The transmission network of the present invention does not limit concrete networking model and network structure, first network can be communication network, the point-to-point communication network such as including wireless communication networks, wire net, the Internet, WLAN, second network can be radio network, especially digital TV broadcasting network, the ability of efficient broadband data to be had transmission.Two-way/uni-directional channels of information can be provided with between user terminal and first network, and between the second network and user terminal, can be uni-directional channels of information.
In the system of the present invention, radio network is optionally to receiving terminal transmission content.The feature of broadcast is that point-to-area information sends, so part is chosen for the content transmission by radio network, and the flow sharing communication network that can be bigger.And although communication network can carry out the data transmission of big data quantity, multiple terminals, but in view of the most growing the Internet and mobile data amount, being sent by broadcasting network by the partial discharge of communication network is a scheme optimized.
In the present invention, communication network sends instruction to terminal, and this instruction comprises the combined information of one or more that radio network starts in the time of transferring content, frequency, subcarrier, code or space.Terminal includes first and second network connection unit, respectively in order to be connected with the second network (radio network) with first network (communication network).After receiving this instruction, extract the instruction in instruction in information such as the time point specified, Frequency point, cluster of subcarriers, code word and direction in spaces, in forming broadcasting tasks information and being stored in the memorizer of terminal, terminal receives the content of radio network broadcast according to broadcasting tasks information at the time specified, channel.Correspondingly, radio network is specified in this instruction time, the content that channels broadcast is corresponding.
For above-mentioned transmission purpose, the content of " chosen " that sent by radio network is the much higher media content of temperature, these multi-medium datas first have to process through content clustering, therefore the present invention can arrange a content clustering module in addition to radio network and communication network on demand, it is connected with communication network and radio network, it is arranged on the front end of radio network and communication network in logic, but the separate server arranged outside this module can be independently of radio network or communication network on physical structure, can also be in radio network or communication network one be exclusively used in word, audio frequency and video process and the specialized server of classification.
Content clustering module gathers the multi-medium data in various source on a communication network, first pass through the sources to content of multimedia, correlation analysis and the prediction of content and user and user to feedback informations such as the click responses of content, analyze the temperature of various multi-medium data, content-i.e. hot spot data that most people is concerned about is picked out, thus content and the common content of high temperature is made a distinction.
Secondly, hot spot data is further processed by content clustering module, feature according to each multi-medium data temperature, extract the keyword of multi-medium data, with keyword, each multi-medium data is made data label, data label comprises a recognition marks, by this recognition marks, all of multi-medium data is divided into hot spot data and non-hot spot data, and all of data label all does unified Content Management in content clustering module.
For each data label, content clustering module needs to constantly update its temperature, thus trasaction key and corresponding recognition marks, therefore the temperature of multi-medium data is the parameter of a dynamic change.Such as within a period of time, certain content of multimedia is paid close attention to by a lot of people, then this content of multimedia will become hot spot data, and over time, become, the attention rate of this content of multimedia just have dropped, now, content clustering module will revise the recognition marks of this data label, and from the content of high temperature, it is become non-hot spot data.Finally, carry out facilitating communications network by radio network and carry out the transmission of hot spot data.
After multi-medium data is divided into hot spot data and non-hot spot data by content clustering module, multi-medium data is divided into two parts by content clustering module: a part is hot spot data, and another part is non-hot spot data.This two parts content is transmitted by content clustering module by two different networks, sends hot spot data to radio network, sends non-hot spot data to communication network.After radio network receives hot spot data, according to the feature of hot spot data, the such as information such as keyword, temperature makes instruction, and wherein this instruction includes the above-mentioned information such as the time of transferring content, channel that start, and sends this instruction to communication network.Communication network utilizes in the terminal that this instruction is sent to need to receive by point-to-point mode.
Channel between radio network and terminal, radio network and communication network can be two logical channels on Same Physical channel, by the way of the time-division works or frequency division work mode multiplexing Same Physical channel, on the other hand the two channel can also be directly two different physical channels.And the channel sending instruction between communication network and terminal is not limited to one-way channel, can be the one-way channel being exclusively used in and sending instruction, it is also possible to utilize existing two-way channel, IP, P2P etc. to transmit instruction.
For user terminal, open broadcast reception module in the time that broadcasting tasks information is specified, receive the hot spot data of radio network at the broadcast channel specified.But the instruction received according to terminal, terminal only just can receive broadcasted content at the time that this instruction is specified, channel, if and terminal is not received by broadcasted content in the time specified, the such as reason such as weak output signal or terminal closedown, terminal still can download this content by communication network in a point-to-point fashion.Further, the broadcasted content that end-on receives carries out integrity analysis, the packet lost in retrieval broadcasted content, the packet lost by downloaded.
Radio network and communication network combination are the trend of new generation network framework, the feature of digital television broadcasting system can be brought into play by such a kind of structure, the content (hot spot data) of high temperature can be separated by the poly-server of content, by making the instruction of hot spot data, the content that most people is concerned about can be carried out direct content transmission, the bigger flow burden reducing communication network by broadcast channel.Such a kind of digital television broadcasting system has provided the user plurality of access modes, farthest provides the user accurate, efficient and high-quality information service.With the information superhighway that the radio network of communication network combination becomes the new period, substantial amounts of multi-medium data can be sent to user by the way of broadcast fast and accurately.
