[0029] specific implementation plan

[0030] Accompanying drawing 1 has described the electronic ground based on streaming media Figure network service method implementation steps .

[0031] The first step: audio and video collection. The audio and video of a certain geographic area can be recorded on tape or hard disk by the vehicle camera, or the audio and video collected can be digitally compressed and stored directly by the video server. Use the global positioning system to determine the geographic information such as latitude and longitude of the collected audio and video, and record the place names, aliases and other relevant information of the collected areas at the same time.

[0032] The second step is to process the data recorded on the tape or hard disk. This processing includes digitizing and compressing analog audio and video using an audio and video capture card. Convert the image size, transmission bandwidth and file format for the digitally compressed files...

Abstract

The invention discloses an electronic map network service method based on streaming media and real-time audio-video rebroadcast, which has two subsystems: a service method based on the streaming media and a service method based on the real-time audio-video rebroadcast. The subsystem based on the streaming media is realized by the steps as follows: 1) images and sounds are collected; 2) the image and sound are digitally compressed to various streaming media play files; 3) the streaming media play files and the electronic map form a relational database; 4) users query the electronic map and the relational database in various modes; 5) a streaming media play server plays the corresponding streaming media play file according to a user request. The subsystem based on the real-time audio-video rebroadcast is realized by the following steps: 1) images and sounds are collected in real time; 2) the image and sound are digitally compressed and transmitted by network in real time; 3) collecting points and the electronic map form a relational database in real time; 4) users query the electronic map and the relational database in various modes; 5) a real-time rebroadcast server rebroadcasts the compressed audio and video according to a user request.

Description

technical field [0001] The invention relates to a new network service method provided by combining streaming media technology, real-time audio and video relay technology and electronic map technology. This method enables network users not only to obtain traditional map information, but also to obtain audio and video information of the area of ​​interest through streaming media and real-time audio and video broadcast. Give users a virtual driving or walking experience. Background technique [0002] With the development and popularization of the Internet, the electronic map system is widely used. Major mainstream websites, such as Sohu, Baidu, Google, and MSN, all provide network electronic map services. Based on these electronic map services, users can easily query various geographic information. Some systems can also list various information such as catering, accommodation, and entertainment in the area of ​​interest to the user. [0003] Traditional electronic maps also...
