Abstract

A method for transferring information from an information provider (100) to an information consumer (190) in a highly efficient manner by means of a digital video broadcasting (DVB, 140) system and a secondary bidirectional transfer network (130). The secondary bidirectional transfer network provides information of where the DVB receiver (191) of the information consumer is located so that only suitable DVB transmitters (146) in the area are used for the information transfer itself. The location is determined by having at least one of either the transmitter frequency, the original network identification, the transport stream identification, and/or the network identification, of a transport stream of one transmitter that the receiver can receive transferred via the secondary bidirectional transfer network. Thereby only the necessary DVB transmitters need to be used for the information transfer, thus relieving the rest of the DVB transmitters (145, 147) from an unnecessary downloading.

In order to illustrate, now some embodiment of its use will be described in conjunction with Fig. 1-4 according to system of the present invention.
Fig. 1 represents the block diagram according to an embodiment of system of the present invention.So figure with following shown in, some part can form less or bigger group.The information that sends information customer/terminal 190 to can be found on information/content provider 100.Other parts of forming this system be information transmit point/service supplier 110, access information database 120, have related cell 145,146,147 digital video broadcasting (DVB) gateway/network supplier 140, auxiliary two-way transmission network/interactive network 130, have be used for auxiliary two-way transmission network 130 DVB receiver 191 with transceiver 192 with selectively be used to handle the information customer/terminal 190 of the device 199 of encrypted transmission.Access information database 120 is used to discern auxiliary two-way transmission network 130 and the access of that network to information customer.The present invention does not depend on that the accurate physics of different piece is close, in logic information customer 190 preferably therewith other parts 100,110,120,130,140 of system separate.For example, information transmits the part that point 110 can be informant 100 or forms a part of or fully independently professional with access information database 120 and DVB network/system 140.As mentioned, have many possibilities, but these do not influence the present invention.
Basically, locating information client 190 of the present invention and only send the position of information to information customer 190 places.The present invention utilizes broadcast system 140 to come transmission information to give information customer 190.Broadcast system is very effective when transmission information is given many receivers.Sometimes, broadcast system is called the point-to-multipoint transfer system.Transmission information is to use so-called point-to-point transfer system for single recipient's (with transmission information from single recipient) traditional approach.The common drawback that Point-to-Point system had is that the transmission information of per unit is very expensive.The very attracting advantage of using the DVB system to transmit information is its great bandwidth, that is, it can transmit the data/information of big (huge) amount in the very short time interval.By location receiver/information customer 190 in broadcast system 145,146,147, the information that can proceed to that position 146 transmits, and can use this network simultaneously by the receiver that the space separates, and makes the transmission of information very economical effectively.The DVB system can have SFN (single frequency network) characteristic, have more traditional television broadcasting characteristic, has the two combination of different frequency field/sub-district 145,146,147 or its, wherein can have the SFN that covers a country or big zone, and also can have several different DVB frequency fields in the same overlay area, each frequency field can be little SFN system.Might SFN and in traditional cell structure the guiding and send different information.In SFN, send different information requirements and very note, but possible.Yet these two kinds of methods preferably require to know the position of receiver, if information to the transmission of single information customer 190 will be effective.The identification of transmitter quantity in the single frequency network is represented in the identification of mentioning transmitter in this specification.The so-called transmission stream that utilization sends from one or more transmitters on predetermined carrier frequency is finished the broadcasting of information in the DVB network.Transmit stream and be for example comprise (only proposing some of them) one or more programs (that is, such as BBC1 with SVT1 and be not the program channel that The limited time is performed), the information of the basic stream of data, business information, condition access control and synchronizing information multiplexing.Transmit stream and be designed for the Polymera application, that is, it generally includes the basic stream that is used for an above program.Basic stream can for example be sound (audio frequency), video, teletext and data, and wherein for example television broadcasting (program) comprises the several basic stream such as video, monophonic audio, stereo audio, teletext etc.Transmission stream according to DVB also comprises data structure, and this structure comprises many information.The present invention is according to one or more information in specific these data structures of DVB network utilisation.Especially, the present invention utilizes DVB to transmit available one or more primitive networks identifications (original-network-id) in the data structure that flows, transmits stream identification (transportstream-id) and Network Recognition (network-id).
According to the present invention, auxiliary two-way transmission network 130 is used to transmit the positional information of information customer to information transmission point 110.A kind of method of acquired information Customer Location itself will be to use GPS (global positioning system) and send this information by auxiliary two-way transmission network 130 and transmit point 110 to information.Yet this can think shortcoming in the time must making information customer comprise GPS.
The information that locating information client 190 other method will be to use the auxiliary two-way transmission network 130 based on the sub-district such as GSM to generate.Unfortunately, that information normally the operator of that network privilege and thereby be not useable for user outside that network.The use of that method will be specific for specific auxiliary two-way transmission network 130 then, and this can think shortcoming sometimes.
According to the present invention, be included in the transmission stream of DVB broadcasting and the information that might be included in the frequency of transmitter of transmission stream of reception is used for locating information client 190.Described transmission flows all transmitter frequencies, primitive network identification (original-network-id), transmit one or more combination of stream identification (transportstream-id) and/or Network Recognition (network-id) with unique identification (among the SFN) transmitter of receiving of receiver and transmit stream thus.Different DVB networks will provide different kinds of information and provide different implications to primitive network identification, the identification of transmission stream and Network Recognition in transmitting stream.In some DVB networks, have and provide the primitive network identification that transmits the stream source and will be enough to, and where this should add and what is added to and transmit on the stream with transmitting information that stream identification will transmit unique identification.If this information is not added to the possibility that the transmission of current reception is flowed, then may need also to use and to specify the frequency that therefrom receives this network of network that transmits stream identification and also might use reception, thereby therefrom receive the transmitter that this transmits stream so that can correctly discern.If discern this transmitter, the selectable transmission stream that DVB receiver 191 can for example receive from the transmitter of identification then have at least possibility identification to have the approximate location of the information customer 190 of its DVB receiver 191 and auxiliary two-way transmission network transceiver 192, so that can be considered.In other DVB networks, primitive network identification may be without any implication, but unique identification transmitter of this Network Recognition and frequency.In these DVB networks, utilizing Network Recognition and only selectively utilizing to transmit to discern is enough to fully.Thereby, according to the present invention, according to described DVB network, obtain transmitter frequency, primitive network identification at least, transmit in the lump it being sent to information by auxiliary two-way transmission network 130 and transmits 110 of stream identification and/or Network Recognition.In other embodiments of the invention, program/the channel and/or the information that receive in the transmission stream such as the reception of server identification, as mentioned above, one is enough at least roughly locate the information customer 190 with its DVB receiver 191 and auxiliary two-way transmission network transceiver 192.Selectively, how receivable transmission stream and corresponding transmitter frequency thereof, primitive network identification, the identification of transmission stream and/or the selectively its corresponding field intensity of Network Recognition transmit together.This makes information transmit point 110 locating information client 190 quite exactly, thereby and determines to transmit the effective and efficient manner of this information.It for example can be the direction that moves that information transmits point 110 criterions that can use, differently transmit vacant capacity, the amount of information that will transmit in the stream, can receive what transmit flow, urgency/priority of the request of transmission information or the like.
