In this file, term broadcast will be preserved for via satellite, the typical broadcast of cable or radio channel or other digital service, and the term distribution will be preserved for the distribution of the service on IP network.
Embodiments of the invention are called a kind of equipment of distribution gateway based on us, and providing of the broadcasting can receive initial conventional digital service be provided for it, and make and can insert on the local area network (LAN) of for example IP network.This equipment is made up of the receiver module that is called as tuner, and this tuner is used to receive the broadcasting of satellite, cable, numeral, radio or other types.Information about the service that is provided by this broadcasting can also be provided on local area network (LAN) this equipment, is used for providing the notice that brings this user with service.When the user selected to be derived from the service that this broadcasting provides, the distribution gateway transmitted this broadcast service in the mode identical with delivery of services server on the IP on IP network.Obviously to those skilled in the art, integrated this function can realize in the diverse location of local area network (LAN) and the various device in this network.
The traditional function of the delivery of services on IP network relates to the service provider, and it will distribute these services.Every kind of service will use multiple spot distribution address to distribute by one or more servers.Exist the service provider it can be provided several ways of the notice that brings this user.At client layer, receiver must be remembered this service and its address that is distributed at the beginning.It makes tabulation to these, thereby it can propose to the user subsequently, and this user will select it to wish the service that receives.This receiver will send to the distribution address of being used by this service and subscribe to inquiry then.This subscription inquiry will cause the configuration of the middle routing device between this server and receiver.The latter will constitute the packet of the stream that comprises this service to receiver from the server route.When this user wants to stop to receive this service, this receiver will be sent in the inquiry of quitting the subscription of this address and will stop to receive bag.
This complete procedure is commonly referred to as the discovery and the selection of service, or SD﹠amp; S (service discovery and selection).The standard that contains this process is called as DVB-IP (digital video broadcasting on the IP infrastructure), and it is recorded at the obtainable reference number of ETSI is among " the DVB-IP Phase 1Specifications Handbook " of ETSI TS 102.034 v1.1.1.
Embodiment of the present invention will be described now.This embodiment is not restrictive, and those skilled in the art can adaptive its some aspect and do not depart from the scope of the present invention.
Fig. 1 illustrates the general frame of embodiments of the invention in its operating environment.Wherein can see, will be connected to the distributing network of the service on IP in the client (reference number 1.4 to 1.6) of a side at the local area network (LAN) on the IP (reference number 1.3).The equipment that we are called client makes and can receive the digital data stream that comprises the service that is derived from IP network.Therefore this equipment is the equipment that can receive the decode the stream on IP.This equipment generally is the IP decoder, it is by forming with lower member: IP network and the feasible demodulation multiplexer that can isolate corresponding to service data packet, be the decoder of the different basic stream that constitutes this service of to decode then, be to make the analog to digital converter to create analog signal, this analog signal will be sent to screen, loud speaker or other to be used to reduce the device of this service at last.This equipment also can be the digital television of direct integrated all these functions.
In the embodiment in figure 1, with the equipment (reference number 1.2) on this distribution gateway construction cost matter, the one side links to each other with native ip network, and has the receiver module that is connected to satellite antenna (reference number 1.1).In this embodiment, this receiver module is a satellite modules, but also can be cable, radio or other receiver modules, as long as it allows received digital data stream (DVB (digital video broadcasting) typically).
For Fig. 2, the hardware structure of the distribution gateway of its illustrated embodiment (reference number 2.2).This gateway is connected to IP network (reference number 2.5) via network interface (reference number 2.9).This gateway has receiver module (reference number 2.3 and the common tuner that is called in those skilled in the art's term).This tuner allows reception sources from signal satellite and that received by satellite antenna (reference number 2.1).This tuner can be adjusted to given frequency, is received in the signal of this frequency emission and reconstruction and is included in digital data packet in this signal.These bags that constitute the digital data stream that is received are handled by the IP filter that is commonly called demodulation multiplexer in those skilled in the art's term (reference number 2.8) subsequently.This filter or demodulation multiplexer can be programmed and be used for extracting the bag that satisfies certain condition (such as the value of certain field the stem of this bag) from stream.The information that this demodulation multiplexer specifically is used for extracting given service from stream or is used for selecting providing about this service that is included in the stream.Usually be called information on services by those skilled in the art about this information that provides.
Interactive operation under the software control of these modules in being stored in the read-only memory of this equipment (reference number 2.6).These services are loaded in random access memory (reference number 2.7), and purpose is to be carried out by processor (reference number 2.4).Be described below the details of details of the main software program of the function that enters this distribution gateway.
Fig. 3 represents equipment block diagram according to an embodiment of the invention.We see that gateway (reference number 3.2) is connected to IP network (reference number 3.5) and satellite antenna (reference number 3.1).From function aspects, we see with lower module: network interface (reference number 3.9), tuner (reference number 3.3) and demodulation multiplexer (reference number 3.8).Will manage by command interpreter (reference number 3.6) alternately between the client of local area network (LAN) and distribution gateway.Command interpreter will receive order or inquiry via network interface from client, and this is represented by arrow (reference number 3.11).For the execution of these orders, this interpreter must be controlled tuner (arrow 3.13).It also will control demodulation multiplexer (arrow 3.15) and stream player (reference number 3.4) (arrow 3.18), and it will distribute the service on the IP network of previous selection again.
According to the commander of command interpreter 3.6, tuner is with receiving digital data bag stream, and it will be sent to demodulation multiplexer (arrow 3.16).The latter will filter the bag that for example belongs to service.These bags are sent to stream player (arrow 3.17), and it is responsible for sending this data packet stream on IP network.Transmission on IP network (arrow 3.19) can be for example via being realized by the Real-time Transport Protocol (RTP) of DVB-IP standard recommendation.Service managerZ-HU (reference number 3.7) will be provided by the management of information on services (that is the information that provides about the service that can insert).This management will realize under the control of for example command interpreter.This service managerZ-HU will receive the signaling information that is included in the stream in output place (arrow 3.14) of this demodulation multiplexer, and can construct the tabulation of available service, this service managerZ-HU can (arrow 3.12) provide (arrow 3.10) this tabulation to the requestor's client on IP network when inquiry.Gone through the management of available service in front.
In an embodiment of the present invention, the distribution gateway carries out following task when its initialization.
Tuner is activated and its preparation that is placed in one receives the state of ordering.This tuner is general tuner, can find in satellite or cable or radio decoding device such as those.Therefore it can carry out the normal work to do of tuner.We mention and browse frequency band to search those functions that are used for the frequency band of service flow broadcasting, function by using given polarization, given modulation and all existing parameters to lock given frequency therein.This tuner also can provide the digital data packet that transmits with given frequency stream.
The tabulation of the service that construction can be received by tuner.We are called the DVB service list with this tabulation, and the service of this tabulation is called as the DVB service.Organize broadcasting link in the following manner.This link is generally shared by several broadcasters.Each broadcaster provides the set of number service, for example with the audio frequency and/or the video of one group of service form.These groups are by one or more transport stream broadcasting.At initialization step, the tabulation of building the broadcaster who shares broadcasting link is usual.In second step, build the tabulation of employed transport stream, and can build the tabulation that is included in the service in these streams at last.
More specifically, in DVB, each broadcaster is identified by single identifier, this network identifier (network id) and can be in table, about seeing in the information table of network or among the NIT (network information table) about its information.This table can find in each transport stream usually, and wherein comprises the tabulation of the stream that is used by each broadcaster.
For each stream, we will find the tabulation of frequency, modulation, polarization and other obligato parameters such as tuner, be used for locking and receive stream.We also can see the tabulation of broadcast service in this stream therein.
For every kind of service, we will see the information of some, such as the tabulation of the identifier of service name, the identifier that is called as DVB tlv triple (triplet), elementary audio and video flowing (PID refers to program identifier).
In stream, can access supplemental services information about the standard of information on services according to the DVB-SI standard.
The feasible tabulation that can construct available service of all these information thus.It is essential that this information becomes the knowledge of broadcast transmission stream, so that can be to its locking and from wherein extracting Useful Information.
The initial treatment mode will be browsed the frequency band that may use, and so detect the frequency band that those are used for launching stream.Detect stream at every turn, therefrom extract the tabulation that relevant information is used to construct available service.This is the common function of tuner.The method is consuming time and monopolize this tuner, this tuner at this moment between during can't be used to receive service.
Also can construct the tabulation of available service according to the configuration file that is stored in other positions of for example distributing gateway or local area network (LAN).This document can be XML form or any other form.The XML form has as the form that is kept by the DVB-IP standard, is used for the encode advantage of this service of on IP network distribution DVB viability.This kind processing mode is faster, still has the actual risk of comparing discarded this canned data with this broadcast service.
Also can be by the tabulation of stores service hereof but mix two kinds of technology by authorizing through more the newly arriving of file of the browse operation of overfrequency, its renewal can be conventional a kind of or according to the renewal of request.
In case be configured in the tabulation of the useful source on the broadcasting link, must have made that this tabulation is available on local area network (LAN).In order to accomplish this point, a kind of possibility is to use the solution by the DVB-IP standard recommendation.This standard proposes the tabulation of IP service is considered as the set of object.Each has wherein following information in these objects: identifier, service name, the elementary audio of service and the near multiple spot distribution address of service identifier (PID), delivery of services of video flowing that for example can be the DVB tlv triple.To make client can insert this tabulation via for example HTTP (HTML (Hypertext Markup Language)) inquiry.
Fig. 4 explanation is to the mode of client distribution services.Client (reference number 4.4,4.5,4.6) is connected with local area network (LAN) (reference number 4.3).The distribution gateway of the assembling tuner of Xian Shiing is not connected with this local area network (LAN) yet.This tuner makes can receive p transport stream (reference number M1, M2, Mp).These are p available stream.By for example satellite transponder (satellite transponder) on given frequency, distribute these stream in each.Tuner can lock onto and allow it to be received in the frequency of the transport stream of this frequency emission.At any given time, tuner can only be received in the single transport stream in the available stream thus.Each transport stream comprises some (such as n 's) service.The reference number of these services is Pij, the label of the i representative transport stream from 1 to P, the label from 1 to n service of j representative in stream.Comprise under the situation that several tuners do not show at gateway, each tuner can lock onto its oneself frequency and receive corresponding stream.This gateway can receive the transport stream number of the tuner number that comprises corresponding to it thus.
The solution that allows to select service will be described now.Specific problem appears here.In fact, the service that provides of standard hypothesis on network based on operation unchangeably.All these services all can insert at any time thus, and like this according to complete separate mode.Be different from this situation, under the situation of distribution gateway, be clear that and move all available services simultaneously.This is due to the fact that: given time in available stream only a transport stream can be received by tuner.To always can not move two kinds of services that belong to two kinds of various flows simultaneously thus, unless assemble this distribution gateway with two or more tuners.Even if but,, just will always will have restriction as long as the number one of available stream exceeds the number of tuner by with several tuner assembling gateways.
Finish delivery of services on IP by using realtime transmission protocol RTP.Traditionally, when client wished to receive the rtp streaming of distributing with the multiple spot ways of distribution, it sent the subscription inquiry that is called as " adding " on multiple spot distribution address.Explain this inquiry by the routing device between the server and client side, to distribute by the bag of server to the client emission.This puts, and server is good based on work under the environment of operation service unchangeably therein.Only under the request just under our situation of example of operation service, this mechanism is not enough to server therein.
For head it off, DVB-IP proposes to use RTSP (real-time streaming protocol) inquiry to allow one of its service of announcement server just by client-requested.The command name of this order is called as " setting ".The use of being somebody's turn to do " setting " order is used to allow to distribute the distribution of gateway management service.Simultaneously, conquering when being engaged in loseing interest in " dismountings " when client butt joint orders and will be sent out.These orders comprise the service of mark to allow gateway identification to be related to by this order.
At first let us is described by the selection of first client to first service.The tabulation of client-requested and all available service of structure.It selects one in all these services." setting " order is sent out gateway and is explained by command interpreter, so that tuner is locked on the stream that comprises institute's requested service.The programming demodulation multiplexer is used for filtering in stream institute requested service, will locate to move this service by the stream player on network to the distribution address of its distribution thus.To be in the position that receives institute's requested service thus by subscribing to this distribution address client.
In addition, gateway ought to know which client asked to be received in the service that moves on the network, thereby when no longer including client it was received the distribution that can interrupt this service when interested.A kind of way of finishing this point is the tabulation of the Service Management client (received about " setting " of this service from it and ordered) for each operation.Thus, when receiving " setting " order and supposition can satisfy this order the time, the tabulation of the client of this service of reception that will join request in the client of order initiation place, we will see not always like this.When the distribution gateway when the client that relates to this service receives " dismountings " and orders, this client will be recalled from it.
In order to manage the access of various users, can between the user, define priority level to serving for the system in for example family (but the mechanism of same type can be used in the company).In order to finish this point, be necessary for each user ID its oneself in the system.There are several ways to realize this sign.For example, in home environment, can be satisfied with the profile that is provided at the selection between several profiles and selects to be correlated with to the user.We wish to realize that we can require the user to input password, start its sign in the head of a family's the more responsive environment of control therein.Certainly, in this problem, can consider many other solutions, for example, the sign of identity card or bioassay parameter.
The application of priority level makes can manage the conflict that takes place between the user.In fact, in case the user has asked to receive service, tuner is locked on the frequency that transmits corresponding transport stream.When second user asked second service, several situations can occur suddenly.Can relate to this identical service in the case, second user enjoys the distribution of service.This also can relate to the service as first service transmission in identical traffic stream.In the case, the simple programming of demodulation multiplexer makes and can extract these two services and distribute them at internal network from the stream that is received.When being different to conflict when broadcasting in first transport stream of serving, second service takes place.In the case, the reception of second service means tuner is locked onto on the frequency of second transport stream.We see that the reception of second service is exclusive to first reception of serving thus.Be necessary to be chosen as which user thus and give privilege.We will utilize priority level to make this selection.
Distribute gateway therein and comprise under the situation of several tuners, this problem finally is identical.Can satisfy all inquiries up to such moment: all service that tuner is locked and user's request is transmitted in the reception in transport stream in the stream that does not receive as yet.
Our distribution of seeing priority level makes and can solve this conflict thus.Yet it also can be used to allow when user request service the user to specify several Retention Levels.In fact, this can occur in the user and wishes the resource that receives service or itself even wish to use in exclusive mode tuner in exclusive mode.
For example, we can consider to define in the family three kinds of priority levels, the preferential Administrator Level of highest level, the people who is used for being responsible for system configuration; Medium rank is regarded as " father and mother ", is used for the adult's access service by family; And low priority is other, is regarded as " children ", is used for the children of family.Very obviously this example is nonrestrictive, and we can define the as many priority level as the member in the family, or the imagination is used to distribute the strategy of other all kinds of these grades.
Can no longer be that the user distributes priority level also according to client device.This makes to give the privilege of some equipment than other equipment except the fact of the identification of steps that no longer needs to have the user.Therefore can give such as recording equipment or (with being considered to less important television set in the kitchen and comparing) at the main television in parlor with privilege.
We also can allow the user in the moment of selecting service, use several retained-modes of the receiving-member of gateway.
First pattern is regarded as " my tuner " pattern, determines the exclusive access of tuner.In this pattern, in case the user has obtained the reception of its service, other are with not using this tuner per family.In other words, nobody can receive service, even if this service is being transmitted on identical transport stream under the help of tuner.
Second pattern is regarded as " my service " pattern, determines the exclusive access to service.In this pattern, second user will be authorized to receive another service by same transport stream transmission, but not be first service that is kept by first user.
Three-mode is regarded as " sharing " pattern, with the access of the service of authorizing second user to keep to the service transmitted on same transport stream and by first user.
Four-mode is regarded as " guest " pattern, will be such pattern: wherein second user can keep by by the service of first user in " my service " pattern or the transmission of the transport stream that receives in " sharing " pattern.
The 5th pattern is regarded as " not keeping " pattern, will not have special retained-mode to be requested.
The system of this reservation allows the user to indicate the user to wish mode that share, its requested service dexterously, but does not allow to avoid the conflict between the user.Can mix priority system and the retention system described to solve the mode of the conflict that may in system, take place thus.
In order to allow to construct the tabulation that comprises about the information of service and the related reserved state that can insert, tuner should provide following information:
● at the tuner layer, its reserved state
● in service layer, the retained-mode of its accessibility and service.
Can consider that gateway is not preserved about whom has kept and so on information.In the case, it only verifies that the rank of reservation and the action of selection are effectively, to receive it.It will be in the scope of the application about client-side management priority and retained-mode then.This mode of carrying out has been simplified the exploitation of broadcast gateway.
In addition, the gateway that comprises several tuners will be distinguished these different tuners, and the tabulation of several services that insert is provided for client.Client will determine its should still not be taken in the associating of its user interface layer that provides they.Another possibility is that gateway is managed single tabulation by the information of uniting each tuner.
But can always provide the access state of each service of indication or the tabulation of available service other information, that upgrade thus to the user.One action by incident management mechanism use selection, this tabulation just can be updated.
The selection of program will cause from client orders to the gateway transmission, and this order comprises identifier, Retention Level (if using retention mechanism) and the user's of service priority level.
Embodiments of the invention are described the situation that tuner allows to receive multichannel, but present invention also extends to the situation of the receiver module of the stream that on IP network, sends, wherein restriction will no longer be the tranmitting frequency of transport stream, but the bandwidth between the broadcasting server of broadcast gateway and service.The broadcasting no matter which kind of technology is used to serve, physical restriction generally limit the number of comparing the service that can receive simultaneously with the sum of the service that can insert.Can apply the present invention to all types of service broadcast modes thus.
