Abstract
The invention aims to combine GPS navigation technology with stream media so as to realize enjoying and playing specific stream media service in moving process. At a terminal C, during the outdoor moving process of the user, GPS function is started and a stream media server S is connected; after the terminal C receives the positioned GPS coordinate data, the GPS coordinate data is sent to a stream media server S through a stream media control command; after receiving the GPS coordinate data, the stream media server S analyzes the coordinates and then searches for the audio and video files corresponding to the coordinates; if the search is successful, the multimedia data is sent to the terminal C; and after receiving the media data, the terminal C plays the stream media. The invention has the good effects that the invention combines stream media technology with GPS navigation technology and can provide richer multimedia video services at real time when a user uses GPS navigation.
Description
Technical field
The present invention relates to the method that GPS navigation technology and Streaming Media carry out combination, method of the present invention is applicable to mobile phone, mobile communication terminals such as phone.
Background technology
Along with closing on day by day of 3G epoch, people's life has more and more been pressed close in the application of stream media technology.Its utilization stream technology is put into continuous image and acoustic information on the Website server after overcompression, encoding process at the transmission over networks multimedia file, watches, listens to while allow the user download.It is powerful interactive, allows the user experience in use to download at any time and watches, conveniently seeing and hearing enjoyment.
GPS (Global Position System) (Global Positioning System is hereinafter to be referred as GPS) is along with a high accuracy, round-the-clock and global radionavigation that development of modern science and technology is set up are located, the multifunction system of timing.Its utilizes the satellite network of being made up of 24 artificial satellites be positioned at apart from more than 20,000 kilometer high of the earth, constantly launches framing signal to the earth.Tellurian any one GPS receiver as long as receive the signal that the satellite more than three sends, through after calculating, just can be quoted position (precision, latitude, highly), time and the motion state of GPS receiver.
But when using existing GPS navigation mobile phone, can only see residing position on map at present, and some Word messages of periphery, the picture dullness does not still have the concrete implementation method that realizes streaming media playing when using existing GPS navigation mobile phone simultaneously at present.
Summary of the invention
Purpose of the present invention combines the GPS navigation technology exactly with Streaming Media, play specific streaming media service thereby be implemented in to enjoy in the moving process.
To achieve these goals, method of the present invention has adopted following step:
Step 1, at terminal C end, the user in the moving process, opens the GPS function out of doors, connects stream media server S;
After step 2, terminal C receive positioned GPS coordinate data, the gps coordinate data are sent to stream media server S by the Streaming Media control command;
Step 3, stream media server S end are resolved coordinate after receiving the gps coordinate data, search for the corresponding audio-video document of this coordinate then, if search for successfully, multi-medium data are sent to terminal C, enter step 4, if step 2 is returned in the search failure;
After step 4, terminal C receive media data, the beginning playing stream media.
In described step 2, step by step following in the concrete execution of terminal C side:
Step S11, transfer the gps coordinate data message that receives to textual form;
Step S12, text is encapsulated by the SDP agreement;
Step S13, the gps coordinate data are sent to stream media server S by the Streaming Media control command.
In described step 3, step by step following in the concrete execution of stream media server S side:
Step S21, stream media server S receive the Streaming Media control command that has the gps coordinate data;
Step S22, by SDP protocol analysis gps coordinate data;
Step S23, according to the corresponding video content of gps coordinate data search;
If step S24 searches for failure, return the information of search failure and give terminal C, if search for successfully, return the search success message and give terminal C, send multi-medium data by RTP to terminal C.
Positive progressive effect of the present invention is: go up above scheme owing to adopt, combine stream media technology and GPS technology, abundant more in real time multimedia video service can be provided when the user uses GPS navigation.

Embodiment
As shown in Figure 1, be the software flow schematic diagram of group method of the present invention, specifically comprise the steps:
Step 1, at terminal C end, the user in the moving process, opens the GPS function out of doors, connects stream media server S;
After step 2, terminal C receive positioned GPS coordinate data, the gps coordinate data are sent to stream media server S by the Streaming Media control command;
Step 3, stream media server S end are resolved coordinate after receiving the gps coordinate data, search for the corresponding audio-video document of this coordinate then, if search for successfully, multi-medium data are sent to terminal C, enter step 4, if step 2 is returned in the search failure;
After step 4, terminal C receive media data, the beginning playing stream media.
Fig. 2 is the software flow schematic diagram of the present invention in end side, and is in the step 2 of earlier figures 1, step by step following in the concrete execution of terminal C side:
Step S11, transfer the gps coordinate data message that receives to textual form;
Step S12, text is encapsulated by the SDP agreement;
Step S13, the gps coordinate data are sent to stream media server S by the Streaming Media control command.
Fig. 3 is the software flow schematic diagram of the present invention at server side, and is in the step 3 of earlier figures 1, step by step following in the concrete execution of stream media server S side:
Step S21, stream media server S receive the Streaming Media control command that has the gps coordinate data;
Step S22, by SDP protocol analysis gps coordinate data;
Step S23, according to the corresponding video content of gps coordinate data search;
If step S24 searches for failure, return the information of search failure and give terminal C, if search for successfully, return the search success message and give terminal C, send multi-medium data by RTP to terminal C.
