Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making all other embodiment that obtained under the creative work prerequisite.
The embodiment of the invention provides a kind of digital home's content service transmission method based on the two-way access module of cable TV, can utilize present cable TV network, carries out the transmission of digital home's content service by set-top box.Below be elaborated respectively.
Be that framework of the present invention is formed structural representation as shown in Figure 1, the implementation procedure of its transmission content service is: media server provides media services, then, inserts set-top box by cable TV network, plays by decoding, thereby is shown to the user.
Data sending processing module: be embedded in the media server part, be mainly used in, or other data, services carry out code conversion, the data that send are carried out some operations necessary to some Video service.
Data Receiving processing module: be embedded in the set-top box end, be mainly used in subsequent treatment is carried out in some services that receive, make it this service and can be good at presenting to the user.
Cable television communication module: be mainly used in the data of transmitting on the cable TV network are carried out modulation.
As Fig. 2, be depicted as the workflow schematic diagram of this inventive method, the steps include:
1, when the user when set-top box carry out to connect the order of media server, this STB terminal at first resets or initializing cable TV and communication module, send an inquiry and connection request to media server, and enter solicited status, its content of query requests comprises: whether the equipment of being inquired about is working properly, and the address of this terminal is provided to media server.
2, after server end data sending processing module receives this query requests, begin to check current service state, quantity and state by the resulting available service of traversal service list, to determine whether to exist this service: if the quantity of available service is 0, then feedback shows the state information that does not have service; Otherwise then feedback shows the state information that has service.
3, after STB terminal receives feedback message from the Data Receiving processing module, by checking whether this message comprises service list and judge whether server end exists service available; If message comprises service list, then and then to the server end of corresponding address send connection request; Otherwise withdraw from immediately and stop the current request state, and do not provide required service in the prompting user current network.
4, after server end receives this connection request, and then feeding back response information gives intelligent mobile terminal, searches for an available passage simultaneously, is used for setting up socket and is tied to a given passage, monitors the connection of intelligent mobile terminal then at this passage; Consider the Share Permissions of household internal Internet resources, can set server end, the terminal use is carried out authentication after receiving connection request from STB terminal.
5, after STB terminal receives response message, create a socket immediately and connect,, and be connected on the known server channels by the server channels that obtains; Send the media services control signal to server end then, comprise channel information, sound size information and switching information etc.;
6, server end receives and confirms this control signal, and will be to should control signal requiring media data to be sent to the Data Receiving processing module of set-top box.
7, set-top box obtains media data from the Data Receiving processing module, it is decoded accordingly, thereby present to the user.
Be illustrated in figure 3 as the workflow block diagram of the content service transmission of this inventive method, the steps include:
(1) monitors after the two-way access module of content delivery service process initialization cable TV whether connection request is arranged,, otherwise continue to monitor if there is connection request then to turn to (2).
(2) listen to the request of receiving after, this process judges whether to exist available service, then turns to (3) if exist, and otherwise sends the message of not having this service, and continues to monitor connection request.
(3) determine that this service exists after, this process initiation is waited for and is received connection request thread, if receive connection request, then the existing interface channel of inquiry is created to connect and will connect and bind and is formulated passage, receives control signal, at last, the desired video stream data that transmits control signal.Otherwise, return continuation and monitor connection request.
Be the structure chart of the two-way access module of cable TV as shown in Figure 4, this structure mainly is made up of two parts: downlink data interface and upstream data interface; Also comprise several optional modules, comprising: RFI module, hardware testing interface module, management interface module etc.To introduce each part respectively below:
(1) downlink data interface: this interface is used for from data such as media server receiver, video, audio frequency, texts.The function that comprises has the function of RF physical interface and demodulator, and to the function that the signal of demodulation carries out the error analysis processing, the position is to the mapping function of byte, and the function of data decryption.The course of work that this module is concrete is: in the radiofrequency signal of down link median filter reception from hfc plant, signal is delivered to demodulator carry out demodulation.Signal after the demodulation through deinterleaving and error correction after pass through the mapping function of data from the bit to the byte again, import the data encapsulation framing into home gateway after the deciphering.
(2) upstream data interface: this interface is used for sending to media server the control information of request msg.The function that the function that comprises has pair data to encrypt, the mapping function that byte puts in place and the function that digital signal is modulated.The concrete course of work of this module is: in up link, user's access request is handled through mac processor earlier, and after system front end was admitted application, home gateway produced upstream data, sends into cable TV through network interface card.Afterwards upstream data is encrypted, upstream data is encoded after the mapping of bit through byte, modulator is modulated upstream data then, sends into the HFC net by filter at last.
Need to prove, contents such as the information interaction between said apparatus and intrasystem each unit, implementation since with the inventive method embodiment based on same design, particular content can repeat no more referring to the narration among the inventive method embodiment herein.
One of ordinary skill in the art will appreciate that all or part of step in the whole bag of tricks of the foregoing description is to instruct relevant hardware to finish by program, this program can be stored in the computer-readable recording medium, storage medium can comprise: read-only memory (ROM, Read Only Memory), random access memory (RAM, Random Access Memory), disk or CD etc.More than to a kind of content-based encrypting and decrypting mode that the embodiment of the invention provided, be described in detail, used specific case herein principle of the present invention and execution mode are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
