2. The mobile phone is used as a "satellite news gathering" SNG camera:

With the recent development of mobile communication technology, it is possible to use video mobile phones as SNG (Satellite News Gathering) cameras, and transmit the shooting pictures back to specific TV channels, saving huge SNG equipment costs.

3.3G video phone:

Using 3G video phone, you can communicate face to face with your relatives and friends far away.

4. Use the msn community:

Add anyone's URL to your msn community, and you can also communicate with him on the Internet.

5. Using Google Earth:

Using Google Earth, you can view satellite photos of all parts of the world online.

6. Using 3G camera:

Connect to the 3G camera system platform of the telecom operator with a 3G video mobile phone or the Internet, select a location where the 3G camera is installed, and then you can obtain the real-time images captured by the 3G camera; you can also use a 3G video mobile phone to directly connect to the chip installed with the telecom operator 3G camera, and obtain the real-time images captured by the 3G camera.

7. The network remote monitoring system of the security industry:

It can be connected to the network remote monitoring system platform of the security industry through the Internet, through which the host computer of the surveillance camera can be connected to obtain the real-time images captured by the surveillance camera.

8. Network remote robot monitoring system for the security industry:

Connect online to the security provider's network remote monitoring system platform. Through this platform, you can connect to a robot equipped with a surveillance camera, and you can control the robot to the location you want to see, and obtain real-time images taken by the robot.

Therefore, if modern people want to watch real-time images of a certain place, they need to use the above eight methods. However, 3G video mobile phone interoperability, 3G video mobile phone and 3G network camera connection, network remote monitoring system, network camera shooting real-time video website , msn, etc., but their methods have their limitations. For example, using 3G video mobile phones or msn, the object must be someone you know, and his location may not be the place you want to see; the installation location and quantity of 3G network cameras are different. It has limitations and cannot interact with 3G video mobile phones; although the number of network cameras installed worldwide has been claimed to be one million, compared with the hundreds of millions of video mobile phones in the world, there is a big gap after all, and there is no such thing as video The mobile phone can add audio explanation and interactive functions, in order to break through the above limitations and meet more needs of human beings, so there is the present invention.

Next, compare the above eight examples with the present invention. The network camera is fixed and cannot be seen in places that are not installed, but as long as the present invention is applied, if you want to see the real-time scene of a certain place or get explanations at the same time to better understand the local area In any situation, as long as there are serviceable video phones in the local area, you can be satisfied. The absence of the above eight cases is described as follows:

The mobile phone is used as a "satellite news gathering" SNG (Satellite News Gathering) camera, but to use this method, you must know the other party's phone number and know him before you can get help from the other party.

The same is true for 3G video mobile phones. You must know the other party's phone number and know him before you can get this convenience. The location of the other party is not necessarily the place you want to watch.

Using online communities for instant communication, such as msn messenger, yahoo instant messaging, etc., you must know each other's website before you can contact each other, or join a common platform, everyone can communicate with each other without knowing each other, but the location of the other party is not necessarily It is the position you want to see.

The disadvantage of using Google Earth is that the database is too large, it is difficult to update the data, and it is difficult to obtain real-time images. Moreover, because the satellite is too far away from the ground, the resolution of the lens is not enough, so it is impossible to see clear images and they are static photos, and it is also impossible to obtain real-time audio. Explanatory and interactive features.

Using 3G network cameras to obtain real-time images has similar functions to network cameras. 3G cameras must be installed in various places, and it will cost a lot of money to popularize them in large quantities.

Use the security company's network remote monitoring system to obtain real-time images. In practice, the security company only allows a few specific people related to the monitoring location to see the real-time image of the monitoring location, and this method is the same as that of the network camera. Sees a location with a camera and cannot interact with it.

Use the security provider's network remote robot monitoring system to obtain real-time images. In practice, the security provider only allows a few specific people related to the location of the monitoring robot to see the real-time images captured by the robot. Moreover, although you can control the robot Get to where you want to see, but distance has its limits.

In view of this, the inventor of the present invention corrects and improves the deficiencies in the actual production, implementation and use of the above-mentioned video and photographic services. With the assistance of many parties, and after many ingenuity and experiments, the present invention was created to provide an application method and system for retrieving real-time audio-visual information at any specific location, so as to improve the use limitations of existing technologies, huge costs, etc. improper omission.

The second embodiment is as follows:

When a demander 1 who has real-time audio-visual needs in a specific location, he enters a specific website 5 in front of a computer 3 with Internet access or holds a handheld electronic device 4 with Internet access, and enters the specific website 5 The specific place they want to see 2, the content they want to see, whether audio explanation is needed, what language explanation is needed, whether interactive instant communication is needed, viewing time and other requirements 21, through the satellite navigation software of this website The map data information system 14 shows the latitude and longitude 12 of this specific place, and the latitude and longitude 12 corresponds to the base station database 6 of the global video mobile phone operator for comparison, find out the base stations 8 of all the telecommunications operators near the latitude and longitude 12, and select these base stations Among the base stations 81, 82, and 83 that are most suitable for transmitting the information of the specific location 2 and other requirements 21 and belong to the same carrier 7, the needs of the specific location 2, the content that the demander 1 inputs, the content that needs to be viewed, whether audio explanation is needed, What language is required for explanation, whether interactive instant communication is required, viewing time and other requirements 21 are transmitted to the base station 81, 82, 83 that has the most suitable information for transmitting the specific location 2 and other requirements 21 near the latitude and longitude 12 The host system platform 13 of the telecommunication operator 7, after the telecommunication operator 7 receives the demand information of the specific location 2 and other requirements 21, through the signal base stations 81, 82, 83 to which it belongs, finds out that the location of the demand is within a certain range of latitude and longitude 12 The video mobile phones 114, 115, 116 which belong to it and have the global satellite 16 positioning function, and locate the longitude and latitude information of the video mobile phones 114, 115, 116, and there are also base stations 84, 84, 85, and then compare it with the latitude and longitude 12 of the demand location, and sort out several video mobile phones 114, 115, 116 that are far and near from the specific location 2 latitude and longitude 12 of the demand. The method of notification is to notify first from the one closest to the above-mentioned specific location 2, and arrange the order according to the distance between the locations, and notify the first priority first. If the first priority is not connected to the service or cannot provide the service, the order will be Notify down, until the video mobile phone user 10 that is willing to provide real-time audio-visual service connects the video mobile phone 114 that provides real-time audio-visual service to provide service, if the above-mentioned video mobile phone 114,115,116 in the certain range of this position all can't be connected, then Report the information that the demander 1 cannot provide the service; another notification method is that within a certain range of the specific location 2, the qualified video mobile phones 114, 115, and 116 will be notified at the same time, and the mobile phone matched by the telecom operator 7 must be the first to connect. If the above-mentioned video mobile phones 114, 115, and 116 within a certain range of the position cannot be connected to the connected video mobile phone 114, then the information that the demander 1 cannot provide the service is reported.

In the present invention, it is an important key of this application method how the telecom operator finds all the video mobile phones that can provide real-time audio-visual information in the vicinity of a specific place effectively, so it is described in detail here:

(A) "Mobile phone base station positioning": also known as GSM positioning method, it uses positioning software to calculate the location of the mobile phone. The distance between these base stations, using this information, using the principle of geometric relative positioning, calculates the longitude and latitude of the mobile phone position. The advantage of this method is that all mobile phones can be located by the base station as long as they are turned on. Above hundreds of meters, to use this method, the mobile phone must be at least three base stations before it can be located. Therefore, in areas with more base stations and high population density, the location of the mobile phone can be more accurately located. However, in areas with few base stations in the outer suburbs, it is not easy to accurately locate.

(B) "Global Positioning System" (GPS): There are dozens of GPS satellites above the earth's ground, orbiting the earth in a 12-hour period, so that any point on the ground can observe more than 4 satellites at the same time. In GPS observation, we can get the distance from the satellite to the receiver (mobile phone or satellite navigation device, etc.), and use the distance formula in the 3-dimensional coordinates to form 3 equations using 3 satellites to calculate the observation point ( or receiver), and then introduce the fourth satellite to solve the error between the satellite clock and the receiver clock. In fact, each receiver can often lock more than 4 satellites at the same time, so each group of 4 can be divided into several Select the group with the smallest error; due to the influence of satellite orbits, satellite clock errors, atmospheric troposphere, ionosphere, etc., the positioning accuracy of civilian GPS is only about 100 meters. The advantage of this method is that the accuracy can be reduced to 100 meters. The disadvantage is that the receiver (mobile phone or satellite navigation device) must have GPS satellite positioning function to be positioned.

(C) Assisted Global Positioning System (AGPS) is an operation mode of GPS. It can use the information of mobile phone base stations and cooperate with traditional GPS satellites to make the positioning faster. Generally, GPS uses 24 artificial satellites in space to triangulate the location of the GPS receiver and provide longitude and latitude coordinates, and requires an open location and requires at least 4 GPS satellite signals for 3D positioning. AGPS is a technology that uses assistance services. It can use the information of mobile phone base stations to download satellite almanac (AlmanacData) by connecting to a remote server, and then cooperate with traditional GPS satellite receivers to make positioning faster. Reduce the time required for positioning.

Ordinary GPS systems are composed of GPS satellites and GPS receivers. Unlike ordinary GPS, AGPS also has an auxiliary server in the system. In the AGPS network, due to the influence of the receiver's working power and geographical location, it cannot obtain For an ideal positioning effect, the receiver often communicates with an auxiliary server with higher power and accesses the network. Although it is related to the coverage of the cellular system, due to the task sharing between the AGPS receiver and the auxiliary server, AGPS is often better than Ordinary GPS systems have faster positioning capabilities and higher efficiency.

In the cellular mobile communication system, the AGPS system uses the mobile phone positioning server as an auxiliary server to assist the GPS receiver to complete ranging and positioning services. The auxiliary positioning server has much stronger power than the GPS receiver to receive GPS signals. In this case, the auxiliary positioning server communicates with the GPS receiver of the mobile phone through the network. With the assistance of the mobile network, the efficiency of the GPS receiver has been greatly improved compared with the time without the auxiliary positioning server AGPS, because there is Part of the work originally handled by the receiver is handled by the auxiliary positioning server. For example, the work from cold boot to warm boot of the GPS receiver is handled by the auxiliary positioning server AGPS.

Normally, a standard GPS receiver needs at least 4 GPS satellite signals to achieve 3D positioning. In addition, sufficient processing power is required to convert satellite data into coordinates, use AGPS to receive GPS satellite signals, and the task of calculating positioning is completed by the auxiliary positioning server.

(D) "Differential GPS" (Differential GPS): referred to as DGPS, which uses known reference coordinates near a specific location (for example: reference coordinates of mobile phone base stations) to correct GPS errors, and then converts this real-time Time) error value is added to the calculation of its own coordinates, and more accurate coordinate values can be obtained. This method can increase the positioning accuracy to an error of 5 meters.

In terms of auxiliary systems for increasing satellite positioning accuracy, the "Satellite Based Augmentation System" (Satellite Based Augmentation System, SBAS) that is currently in operation around the world includes WAAS in the United States, EGNOS in the European Union, and MSAS in Japan. The working principle of WAAS is That is, WAAS includes about 25 ground reference stations, which are scattered in the United States and are responsible for monitoring GPS satellite data. Two of them are located in the main stations on the east and west coasts of the United States, responsible for collecting data from other stations and calculating accordingly. The GPS orbit offset, electronic clock error, and information delay time caused by the atmosphere and ionosphere are collected and propagated through the synchronous satellite on the equator. The sending frequency of the WAAS signal is the same as that of the GPS signal, so Any GPS machine with WAAS function can receive this signal and use it to correct the positioning information.

To do DGPS differential positioning, it is indeed necessary to have evenly distributed ground reference stations to work together, and the establishment of ground reference also requires the infrastructure (Infrastructure) that has been completed or is actively in progress in advanced countries. For example, the National Geodetic Survey of the United States ( The CORS system of NGS) has about 300 CORS stations in the United States and overseas Alaska and Hawaii and surrounding areas; Japan’s Ministry of Construction and Geosciences has more than 1,200 electronic reference points; Taiwan also has nearly 300 GPS continuous monitoring stations, these Stations usually receive GPS satellite signals to set national coordinate references (such as TWD97 coordinate system), crustal changes, earthquake forecasting, etc. Of course, these reference stations can also be used as ground reference stations for the DGPS system, but these ground reference stations may be due to Factors such as environmental protection protests or expenditures cannot be widely popularized in the world, so the idea of the present invention is to use the existing mobile phone base stations to double as the ground reference stations of the differential positioning system (DGPS) for collaborative work, and it itself is provided by the construction unit. Or the operating unit completes the construction of these ground reference stations, data connection, data analysis, joint calculation of precise coordinates and positioning error data at each time (Epoch), uploading (to geostationary satellites), dissemination (to other stations) and other infrastructure work. As for the latitude and longitude coordinates of the GPS chip of the video mobile phone, how to be retrieved by the base station as a comparison reference with the latitude and longitude of the specific location desired by the demander, so that it can find the video mobile phone closest to the specific location. The GPS chip in the video mobile phone with GPS positioning function can output the $GGA standard positioning result data (ASCII) format in NMEA0183 (National Marine Electronics Association, NMEA) as soon as it is turned on. For example, the format is: $ GPGGA, 102211.000, 2409.1111, N, 12038.2222, E, 2, 09, 1.0, 105.7, M, 0.8, 0000*7F where 2409.1111, N stands for 24 degrees 9.1111 minutes north latitude; 12038.2222, E stands for 120 degrees 38.2222 minutes east longitude, this standard The positioning result data can be transmitted to the host system of the telecommunications operator through the base station, and used to compare with the input longitude and latitude of a specific location, so as to find the closest video mobile phone that can shoot real-time video and audio near the specific location. This method can Reduce the GPS positioning error of the mobile phone to within 5-20 meters.
