The present invention mainly realizes becoming Bluetooth protocol to send to the other side's bluetooth equipment the data transaction that serial ports receives, and will convert serial data to from the blue-teeth data that the other side's bluetooth equipment receives and send to equipment.Because most of families all have been equipped with PC now, therefore streaming media server directly can be set up on family's PC and, need not to use needed media resource, and watch video by mobile device by service provider as source of media.
Could connect between server end of the present invention and the intelligent mobile terminal, can be achieved by following concrete measure:
Its content of the query requests that intelligent mobile terminal sends in the described step 1) comprises: the device address of its address of the equipment of being inquired about, title, the service that is provided and this terminal self;
Described step 2) server end is checked the current service state by the quantity of the resulting available service of traversal service list in, to determine whether to exist service; If the quantity of available service is 0, then feedback shows the Service_none state information that does not have service, and its content of this information only comprises server end device address and title; Otherwise then feedback shows the Service_exist state information that has service, and its content of this information comprises server end device address, title and service list;
The feedback message of intelligent mobile terminal to receiving in the described step 3) is by checking whether this message comprises service list and judge whether server end exists service; If message comprises service list, then send connection request to corresponding server; Otherwise withdraw from immediately and stop the current request state.
The present invention judges whether to have service according to the situation of server end service list, and then determines whether to connect.When connecting when the service existence, server end receives the connection request of intelligent mobile terminal in the step 4) of the present invention, and then feeding back response information is given intelligent mobile terminal, search for already present RFCOMM (twireless radio-frequency communication) passage by SDP (professional search protocol) simultaneously, set up a Socket and be tied to a given RFCOMM passage, monitor the connection of intelligent mobile terminal then at this passage; After intelligent mobile terminal receives response message, create a Socket immediately and connect, obtain the server end channel information by the SDP inquiry, and be connected on the known service channel.
Consider the Share Permissions of household internal Internet resources, can set in the step 4) of the present invention after server end receives the connection request of intelligent mobile terminal, the terminal use is carried out authentication; Authentication mechanism can adopt cell-phone number coupling or cryptographic check mode; For PC server end and intelligent mobile terminal that Windows operating system and WinCE are installed simultaneously, also can adopt the integrated authentication of Windows.
The inventive method can take following measure to realize its process:
Streaming media server end of the present invention and intelligent mobile terminal are realized the transmission of data based on following assembly:
Main transmission part-be nested in the streaming media server end is used to receive the control signal of processing from intelligent mobile terminal, and to intelligent mobile terminal transport stream media data;
From transmission part-be nested in intelligent mobile terminal, be used to send the Streaming Media control signal, and receive stream medium data from server end;
Described bluetooth communication is arranged on the described master and slave transmission part, based on the Bluetooth wireless transmission technology, be used for the translation data form and support duplex communication.
Because server end master transmission part of the present invention adopts bluetooth communication to communicate and serve issue, so other bluetooth equipment such as bluetooth PDA, also can search these parts, thereby find its service and utilized.
The present invention has following beneficial effect:
(1) the present invention introduces the Bluetooth wireless transmission technology aspect the Streaming Media transmission of digital home network, by short distance high transfer rate, high stability, high sensitivity that Bluetooth communication had and can connect the characteristics of a plurality of elements simultaneously, realize convenient the sharing of media resource of digital home's Intranet, be applicable to short distance (10～100 meters) transfer of data of household internal network, low in energy consumption, can connect a plurality of elements simultaneously.
(2) utilize most of now families all to possess the good condition of PC and intelligent mobile terminal, with family's PC as source of media, expanded the sharing of media resource, do not needed to use required media resource, saved user's use cost by external service operator; The terminal use uses mobile device can watch video, has changed the watching mode of fixed position in the past, thereby provides home media service easily for the user.
