Description

  The present invention relates to the fields of wireless mobile communication and Internet communication. More specifically, the present invention relates to a system and network structure that provides users with objective real-time real-time services according to demand using a wireless mobile communication network and the Internet, and a real-time content collection, distribution, and management control method. Is.

  Currently, the penetration rate of mobile phones is very high. Taking China as an example, the number of mobile phone users in mainland China reached 450 million at the end of 2006, and this data reached 480 million in May 2007. Not only mobile phones but also internet applications are quite popular. For example, in December 2006, the number of Internet users in China reached 137 million, and in May 2007, the data reached 144 million. As the number of mobile phone users and Internet users rapidly increases in this way, it provides a huge market opportunity for a group of mobile phone users and Internet users. Mobile phones and the Internet are changing people's lifestyles without knowing them, and becoming indispensable for people's daily lives and work.

  Direct access to the Internet using a mobile phone will become more common with rapid development of Internet services on mobile phones, continued enhancement of mobile communication terminal functions, and increased mobile connection speeds. . New operations are being developed more and more to meet the demands of the telecommunications market. In the mobile communications network, the voice business is now the main business, but with the development of the multimedia business and the fusion of the wireless mobile network and the traditional Internet, a new video business has taken it. Instead, it can be the main work of mobile operators and service providers.

  Existing wireless mobile communication networks and the Internet already provide users with some video work. These operations include stream media services, video telephony, network cameras, real-time traffic monitoring, crime monitoring, and the like. There are two main types of video services: non-real-time video services based on memory and real-time real-time based on users' real-time requirements.

  Youtube system is a typical example of non-real-time video services based on memory. In this system, a video sharing website is created, and support for video content of various types of formats is provided, so that the user can freely upload or download video content that the user likes. Since the video content stored in this system is a video produced in the past or a recorded event that has already occurred, the service provider creates a search catalog for these content. As a result, the user can quickly search for a favorite content. Such a non-real-time video service based on memory makes it relatively easy for a user to search for content he / she likes. However, in such a service, wireless mobile users and Internet users witness the real objective world in real time at a long distance in accordance with their own demands, so that incidents occurring in the real world cannot be made real time to the user.

  Services that obtain real-time real-time real-time video based on real-time billing by users include urban traffic monitoring systems and critical location crime monitoring. A service provider installs a camera at a specific location and distributes content to a necessary user through a mobile communication network or the Internet. Through this work, a real-time service for a single content of a real scene is provided to the user. However, it is still impossible with existing systems to search for real-time real-time content that the user likes from various real worlds according to demand.

  By using cameras and sensors to collect video and audio data in real time in the objective world, and uploading the collected content to the network, users can view real-world video, audio and other data in real time via the network. To be able to get information. There is a great demand for real-time data acquisition from users in real time. These demands are as follows.

  1) Real-time information is acquired in real time. Since the objective world is constantly changing, the user always needs to grasp the situation of a specific place at a specific time. For example, there are cases where the user wants to know the vacant seats in the parking lot before leaving or during the course of shopping at a department store by car or eating at a restaurant. If you go by bus or taxi, if you meet a traffic jam, be curious or decide if you want to change or wait, you just want to know what happened before and check the previous road conditions in real time through your mobile device There is hope to want. In addition, if you are going on a trip, you can preview the situation of the tourist spot in real time at a long distance, understand the specific video information of the tourist spot, then select the appropriate departure time, route and destination Save time and money.

  2) Enjoy entertainment programs in real time. There are many meaningful or interesting events in the real world, and if you upload these scenes to the network in real time, people can search and click to enjoy them. As a result, it is possible to satisfy the user's leisure entertainment demand and increase the enjoyment of life. For example, if a telescope is installed on the moon or space station and connected to the Internet and a mobile network, the user can observe infinite space in real time and experience the astronaut's sensation without flying to the space. Also, if you combine it with the appropriate lighting for the camera in the undersea world, or install the camera in the shallow water and install a large electronic album on the wall of your home, you can see the real undersea world scenery at any time in the house. I can appreciate it. If you install a few cameras in the wild zoo and connect to the Internet and a mobile network, you can appreciate the living conditions of wild animals using the home computer or mobile communication terminal through the video distribution system. In addition, cities around the world have a large number of theaters and stages, and users can upload these programs to the network in real time using a camera and deploy an easy-to-use content distribution system in the system. You can download on demand and watch your favorite programs.

  3) Real-time incidents and news in real time. In daily life, there are sometimes sudden incidents and news incidents with high news value. For example, there are accidents such as volcanic explosions, tsunamis, and train rollovers. If a user is at the site of the incident and uploads the video and provides related keywords describing the video's attributes, such as volcanic explosions, tsunamis, train overturns, etc. A user who wants a scene can be easily found.

  4) Conduct field research at a long distance in real time. Researchers can take on-site data such as volcanic explosions, study hydrology, plant growth, and animals at a distance from the office through cameras and sensors installed at volcano mouths, river and lake shores, and forests. You can observe your lifestyle.

  5) Real-time education at a long distance. There is already a network education program. Many are predetermined for the user, that is, the program has already been received before the educational program is received. As a result, the user needs to receive a desired education using the network at a specified time. In addition, most of these online classes are conducted in schools. The new real-time education is very different from this model. First of all, the places where class content is offered have spread from simple campuses to every corner of the world. For example, a class on weapons development history may be held at a military museum. Ocean diving classes may be held in the water. A botany lesson takes place in a botanical garden. This can be done by uploading lesson content in real time using a camera and distributing it to the end user using a distribution system. The current network education is set up by the class provider's own idea, and the user is passive and can only select his / her favorite content from this limited class type. However, a new educational real-time program provider can build a mechanism for holding or deleting a program based on the user's preference for the program. For example, assume that a real-time program provider prepares many types of educational real-time programs for users. The user distributes lesson content to the end user according to demand (for example, by a search or customization method) through the program provider's content distribution system. The user selects a favorite program according to his / her hobby, program quality, and the like. After a certain amount of time, a small portion of the program may attract more than 90% of users. At this time, program providers may not deliver less popular programs due to cost. New educational real-time programs become user-driven program competition models, whereas traditional network education (eg, educational programs based on traditional mobile phone TV) is passively user-designated by the educational program provider. It becomes a program selection model to receive. Needless to say, the new educational program model is closer to the user and reflects market demand more.

  6) Other scenes that need to be grasped in real time. Examples include city traffic information, crime prevention, forest fire monitoring and warning.

  In addition to the demand for acquiring real-world video and audio content from the network described above, there is a demand for providing real-time content to the public through the network. There are often interesting events and major news outbreaks in my life. Examples include UFO sightings, terrorist attacks, and volcanic explosions. Due to the sudden nature of the incident, professional journalists often cannot reach the scene in the first hour when these incidents occur. On the other hand, mobile users are distributed over a wide range, in which cameras are installed on terminals of many mobile users. On-site witnesses of this incident may want to upload the incident to the network in the first hour with their mobile phone camera. The real-time distribution system can distribute this content in real time to mobile users and Internet users who are interested in the incident.

  Many related technologies and systems have been submitted to meet the needs of obtaining information from and providing information over the network. The Youtube is one of the typical examples. This system allows users to freely upload or download video content they like by establishing a video sharing website and providing support for video content in various formats. However, as mentioned earlier, although youtube meets the need to obtain information from the network and provide information through the network, the system is limited to non-real-time content, ie it can be provided The only content that has been produced is a pre-made program. Even if it was a program that recorded a real-world incident, it was already over when it was uploaded to the network. Therefore, YouTube cannot provide users with real-time real-time services.

  Patent document 1 is disclosing the information processing system which provides a service by electronic map information. The system server has an electronic map information database including electronic map data, and an on-site information database of information relating to an arbitrary direction in the electronic map transmitted from the terminal device. The server distributes necessary site information to the user in response to the user's search request based on the site information related to the electronic map organization. The terminal device can read or rewrite the field information correlated with the map position in the database. This system well meets the demand for “information acquisition” and “information provision” through the network. However, the system is essentially a “non-real-time” system that simply provides electronic maps and related information services, and cannot provide real-time “real-time” operations. At the same time, if it is desired to grasp real-time field information where a certain end user is, this system server cannot request the latest data from the user at the relevant location according to the request of the end user. In other words, the system cannot dynamically collect the data that it wants to follow the end user's request. In addition, this system distributes content by itself, but does not support content distribution by a third-party distribution system.

  Patent Document 2 discloses two kinds of real-time video information sharing systems and methods. In this system, a video index server is installed. The server is connected to each stream media server that generates real-time video information, and receives and stores real-time video resource information transmitted from the media server. Each user terminal obtains real-time video resource information by accessing the video index server, and downloads and plays real-time video information from the corresponding stream media server according to the real-time video resource information. The system also supports requesting real-time video from each terminal to the real-time video resource index server. The real-time video resource index server acquires real-time video information from the stream media server according to the real-time video resource information and transmits it to each user terminal. Using this method, real-time information real-time information in the objective world can be provided to the user. However, this method does not support dynamic collection of real-time information. At an incident site in the objective world, a mobile communication terminal user of a portable camera cannot upload and contribute to the server in real time for the Internet and mobile users in real time. In addition, this system server responds to a request from an end user in real time in real time in a specific place at a specific time, and invites a mobile communication terminal user of the mobile camera in the area Can't be uploaded and real-time meeting demand. In addition, this system distributes real-time content by itself, but does not support distribution of real-time content by a third-party distribution system.

  Patent document 3 disclosed a method and system for instantly communicating and sharing audio and video. However, this method only supports peer-to-peer audio and video sharing, but does not support dynamic collection of real-time real-time information in the real world.

  Patent Document 4 discloses a shared video on-demand transmission method. This method mainly examines how to improve the efficiency of video request transmission, but does not consider the video data collection function.

  Patent Document 5 discloses a method of sharing network content, a receiving device, a source device, and a message structure. This system only supports point-to-point video sharing, but mainly for local networks, not for large networks such as the Internet and mobile communication networks, and at the same time dynamic collection of video data Also not supported.

  Patent Document 6 discloses a television news material transmission / sharing system via the Internet. What is shared by this system is TV news material, and these materials can be shared only via transmission over the Internet. The users in this case are limited to TV program producers, but are not ordinary Internet or mobile network users. In addition, the system does not support dynamic collection of that content.

  Currently, many camera devices are installed in the world. This camera is installed in places such as parking lots and ski areas and is connected to the Internet. Such a camera is called a net camera. Internet fans categorize and organize these cameras for convenient access from Internet users. The user connects to a camera according to the result of classification by the fans. And the real-time scene image | photographed with these cameras is observed in real time. However, the content provided from these cameras is real-time, but only satisfies the user's temporary curiosity and cannot provide more information and entertainment to the user.

  First, an ordinary Internet user searches for a corresponding camera and observes a real-time scene based only on a clue provided by Internet fans. Since the camera provider does not describe the attributes of the content provided by the camera, the user cannot search for favorite content according to his / her demand. In addition, the owner of the net camera cannot recover the cost by making a charge from the last information user. For this reason, the distributed network camera system cannot be developed as a universal tool for providing real-time information and entertainment to users. In the current Internet model, most websites are open to people for free. A large amount of valuable information is distributed at each site, and it is difficult for users to directly search for their favorite content in the face of a large amount of information resources. Search engines search for relevant content free of charge based on keywords provided by users and distribute them to users, providing a simple and fast way for users to find their favorite content. The user group is sucked. When an owner (for example, an advertisement distributor) of a certain content server wants to increase the click rate of his / her content, the search engine owner obtains a search keyword of the user and then embeds the content in the search result and distributes it. However, the search engine owner charges from the content distributor. Although each search engine is slightly different in terms of content, it is only a way of ranking searched information as a main distinction. For example, the search engine owner can use a so-called “auction ranking” or rank the user according to his / her preference according to his / her strategy. The search engine owner submits a list called “click rate” to advertisers who have contracted regularly or irregularly, and bills advertisement distributors for advertising costs based on this “click rate”. For ordinary users, the information provided by the search engine is “free”. In other words, search engines use 99% of the Internet's free information to attract a vast number of Internet users, guarantee the experience of those users, and click on their content that accounts for 1% Charge from owner and get 99% profit. In such a case, the search engine owner can charge from the content provider, whereas the content provider cannot charge from the search engine owner.

Therefore, no matter how interesting content the net camera owner provides, no text can be received from the search engine owner or the end user, and of course, the initial investment, operation and management costs cannot be recovered. With the current model, the motivation for the camera owner to install the camera is only self-interested, the camera maintenance and content management are difficult, and it cannot be developed into a universal tool that provides real-time information and enjoyment to the masses. .

Real-world real-time systems make full use of control mechanisms for mobile users from mobile networks to quickly transmit content customization requests and feed back conditional mobile users to meet content customization demands. Is possible.

  The above and other objects and novel features of the present invention will become more fully apparent when the following description of the embodiments is read in light of the accompanying drawings as follows.

(Embodiment 1)
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the description, details and functions that are not necessary for the present invention are omitted in order to avoid confusion in understanding the present invention.

  In this specification, the term “real time” is often used, and because of the importance of the concept, first, “real time” in the real world will be described. First, the meaning of “delay” will be explained. “Delay” refers to the time interval from the time when an incident occurred to the display time when the user received video, audio, etc. of the incident. In “non-real-time” operations such as the Youtube system, the “delay” is composed of three parts. The first is a delay in content collection. This delay is a time interval from the incident occurrence time to the time when the video / audio content of the incident can be uploaded to the network server and downloaded by the user. The second is a delay in the content stationing at the server. It is a time interval from the time when the content is uploaded to the server and waiting for the user to download until the time when the content server receives an acquisition request for the content from the end user. The third is a delay in content transmission. This is the time required to transmit incident content from the server to the end user.

  In contrast, in the real-time real-time “real-time” system according to the present invention, the “delay” is composed of two parts. The transmission delay is the same regardless of “non-real time” or “real time”. The main distinction between “non-real-time” and real-world “real-time” is that in real-world “real-time” operations, the content is not stationed on the server (however, because the content is distributed to multiple users, the content is This accumulation time is very short, much shorter than 1 second, usually tens of milliseconds, and even tens of microseconds, so it is considered zero). On the other hand, in the “non-real time” business, after the content is uploaded to the server, it is stationed at the server and waits for reading from the user. This residence time can be seconds, hours, days, months or longer. In addition, the delay in content collection differs significantly between “real time” and “non-real time” (for example, YouTube). In the “real-time” system, content such as video and audio is uploaded to the server as soon as the incident occurs. In the “non-real-time” system, the content of the incident is uploaded to the server after the incident ends, and the incident ends. Later, it may be uploaded after a certain time by the producer.

  In order to provide information such as real-time video and audio in the objective real world to mobile users and Internet users, field cameras and sensor devices are installed in the objective real world, and these devices are connected to mobile communication networks and the Internet. A real-time content distribution system may be deployed. Users can acquire their favorite content using these distribution systems. However, in order to realize the real-time real-time system according to the present invention, first, the following problems must be solved.

  1. Real-time content control and protection. As mentioned above, in the current Internet industry operating profit model, network content providers have three choices: to release the content to the public for free and to distribute the content at a cost to search engine owners. And receiving the content yourself. For non-advertising content providers, the provided content meets the demand for information acquisition and entertainment for the Internet and mobile users, to recover equipment implementation costs and system operating costs, Since the end user of the information must be charged appropriately, the content cannot be released to the public free of charge, and it is even more impossible for search engine owners to pay and distribute it . It is difficult for many small content providers to distribute content themselves because they are unknown to ordinary Internet and mobile users. A method that is commonly adopted by ordinary users is to use a search engine to obtain their favorite real-time content.

  In order to solve this problem, a real-time content provider can install a content server and install an access control unit in the content server. When a content distributor on the Internet or a mobile network wants to distribute content on a certain content server, the distributor must first obtain the authorization of the content server owner. The access control unit performs authority management for the content distributor and performs authentication for each received distribution access request. After installing this access control unit, the real-time provider can arrange the distribution server by itself and distribute the content, or release the content to the distribution service provider who has signed a contract. If real-time content provided by a content provider is real value and popular with the Internet and mobile users, search engine owners want to provide this real-time content to their users to improve their experience If so, you must first consult with the owner of the real-time content to receive permission. Then, the search engine owner pays the cost to the real-time content owner and distributes the content. Thus, the introduction of a new feature with the access control unit in the content server changes the operating profit model of the conventional Internet industry. Since the access control unit is installed in the content server, this unit guarantees that the content of the content server is open only to the distribution server authorized by the contract. Real-time content that is of real value and that the user likes (eg, real-time content for city traffic, real-time content for vacant seats in city parking lots) would be popular with users. Users also want to pay for such services. It should be noted that current Internet users are accustomed to free information services, while mobile users are accustomed to paid services. Based on this situation, in a new model, it is conceivable to combine a mobile terminal of a mobile user and an Internet account number to provide a real-time real-time service to the user.

    2. Wide range coverage with low cost of equipment such as cameras / sensors. In order to provide users with real-time information on the real world, a more direct method is to install cameras and sensors on the site in the world and connect to the Internet and mobile networks. However, since the geographical area we want to cover around the world is very large, it is not realistic to install cameras and sensors everywhere. In view of the fact that mobile communication users are distributed all over the world, and the mobile communication terminals of many people among them are equipped with camera devices, real-time content providers are thus mobile communication distributed in various places. Other users dynamically collect content that is of interest by devices such as the camera of the terminal. That is, the content collection unit in the content server is divided into two parts: dynamic content collection and static content collection. In the dynamic content collection model, any camera or sensor can dynamically join or leave the server. In other words, the imaging device or the sensor device can temporarily provide specific content to the content server at a specific time or place. In the dynamic content collection model, any mobile communication terminal user in which a camera is installed can be a potential content provider. In the dynamic content provider subscription method, the content server may passively receive the user's subscription request, but the content server mainly invites a user in a specific area to provide real time of the scenery there. Good.

  In the static content collection model, the content server owner can install the shooting and sensor devices in some areas and connect to the content server. Alternatively, it is also possible to receive a photographic contract or a sensor device provider's photographic or sensor device and make a fixed connection to the content server. These information collection devices continuously provide a real-time information stream to the content server. By combining dynamic content collection and static content collection, it is possible to realize an economical wide-area coverage by a real-time real-time information collection device. In addition, when a mobile operator installs a real-time real-time service system, the mobile operator can also install a camera at a cell base station or a relay base station. A mobile operator can also rent a camera to a real-time content server owner by installing a camera at his cell base station or relay base station. Since the field of view of the cell base station or the relay base station is relatively wide, these photographing apparatuses can collect real-time video information in a large area. After collecting the video information, it may be further classified using processing software for distribution, and the user's favorite content may be extracted.

  3. Real-time content management and detection. After uploading the real-time information stream of the site collected by the photographing of the real objective world and the sensor device to the content server, these contents are distributed to the user by the content distribution server. For this reason, the content distribution server must grasp the content uploaded from the photographing or sensor device. In order to guarantee the legality of the distributed content, the real-time service provider needs to understand the distributed content in order to control the distribution. However, although the objective world is different, the information collection device can only upload to the content server as it collects video, audio or sensor information streams. Cannot identify what content should be included in the information uploaded by the collection device, except for image capture devices (eg, city traffic information cameras) installed for special purposes, and inform the content server of the content of the video stream to be provided I can't. If there is no attribute description in the content of the shooting or sensor device, it is difficult for the real-time system to search the user's favorite content in response to the user's request from this video or audio information stream. In order to solve this problem, an attribute description related to the collected content may be attached. This attribute may be provided from the content server or set by the content provider. It should be noted that the content server has two types of content collection models, static and dynamic. In the case of dynamic collection, the content provider (typically a mobile user) must provide the content and provide some keywords to the content server to describe the content attributes. These attributes include, but are not limited to, content description, image size, incident geolocation, etc. In the case of static collection, the content server sets a content attribute keyword such as a character string related to the geographical location of traffic information, for example. When setting a content attribute string by a content provider, the content server checks whether the content description matches the provided content attribute either automatically or manually (automatically or manually) ) The content server can mainly check the content or check the content based on feedback from the end user (for example, an appeal against a certain content). In order to manage real-time content, the content server owner creates a blacklist and trust level system, updates the blacklist and user's credit record according to the check result against the content attribute, and also updates this blacklist and trust record. Use content providers to manage content fraud. The content server prepares content and keywords that describe these content, and can easily search for real-time content that the user likes. If the detection technique is developed until it becomes easy to directly detect the content attribute by the video content, all the attribute character strings may be set by the content server. There are cases where a lot of users are attracted to a certain real-time content even hours, days, or months after the occurrence of the incident. In other words, content such as incidents that have important news value and enjoyment of life that the user performed by themselves is worth re-broadcasting. This content should be stored in the content server simultaneously with the real time. However, since there are so many real-time contents in the real objective world, the content server cannot store all real-time contents. Therefore, when the content provider sets the content attribute, it is necessary to make a judgment on the possible value of the content provided by the content provider. Since it may not be free to store the content, the above-described determination sets whether the provided content is stored in the content server or how long it is saved. Of course, if it is not possible for the user to determine whether the content to be uploaded is popular with the public, the storage time of the content by the server may be set short when uploading. If the content is very popular after uploading, you can extend the storage time.

  4). How to provide users with real-time services that meet demand. If a real-time real-time system is used, a content provider can distribute real-time content to end users by a distribution server. Since the access control unit is newly installed in the content server, it is possible to simultaneously authorize one or many third-party distribution service providers and distribute the real-time content. In a system that provides users with real-time services that meet demand, a distribution server distributes using the following three types of distribution models. (A) Search model. Since the network user does not know where the real-time content he wants is located, he / she enters a keyword and searches for his / her favorite content. This is a popular real-time content distribution model. The user searches for real-time video using location location information (for example, place name, location coordinates, etc.), content attribute keywords, video size and rate that can be supported by the mobile communication terminal, and the like. (B) A customized model that responds to user demand. In a customized model, a user may send a specific real-time billing to a real-time server, and if the real-time provider does not already have the real-time content, it may use the dynamic content collection model to collect the content the user wants. unknown. For example, when the end user A wants to see the scenery of Hawaii Beach in real time, after transmitting a charge to the content distribution server, the charge is transmitted to the content server. At this time, if there is no Hawaii beach real-time content in the content server, the dynamic collection function is activated to request the mobile user on Hawaii beach to upload the beach situation. If the mobile user B of the portable camera in this area receives this request and provides a video of the beach, the content server connects the content uploaded from the user B to the user A in real time, Meet demand. Note that the end user can also customize for real-time content that may occur in the future. For example, if a user in S city wants to enjoy a children's play at home with a child, he / she requests a customized service through the distribution server as follows. In other words, if you find a theater that has real-time performances from 7:00 to 8:00 tonight, the children ’s puppet theater “Snow White” and “Cinderella”, please let me know in real time. (C) Bulletin board system. The distribution server announces popular content to the real-time posting system, making it convenient for users to access.

  Next, the connection relationship of each component in the content server 103 will be described. A camera / sensor that dynamically requests access to the content server 103 is connected to the dynamic collection device 203. Cameras / sensors that are permanently (permanently) accessed to the content server 103 are connected to the static collection device 204. The camera / sensor may be the photographing / sensor device 101 mounted at a fixed position, or may be the photographing / sensor device 102 installed in the mobile communication terminal. The static collection device 204 collects information transmitted from an information collection device such as a camera / sensor fixedly connected to the content server 103. These cameras / sensor devices are fixedly connected to the content server 103 according to a prior setting. The dynamic collection device 203 collects information transmitted from an information collection device such as a camera / sensor that is dynamically and randomly accessed by the content server 103.

  Real-time content uploaded from the cameras / sensors 101, 102 includes attribute descriptions associated with this content either externally or implicitly. This attribute explanation provider may be a provider of real-time content. Usually, the attribute explanation provider may be a mobile terminal owner or a fixed camera owner who provides real-time content, and may be a content server owner.

  The dynamic collection device 203 and the static collection device 204 collect real-time data, and then transmit the collected data to the real-time content processing device 206. The real-time content processing device 206 performs real-time signal processing on the collected data. Usually, the real-time content processing device 206 performs classification and storage processing on collected real-time data, and distributes real-time content in a multi-transmission manner. The real-time content processing apparatus 206 compresses real-time data to save its transmission band. In addition, the real-time content processing apparatus 206 performs channel coding on the real-time data in order to increase the reliability of data transmission.

  The content management device 205 is connected to the real-time content processing device 206. The content index device 207 is connected to the content management device 205 and the real-time content processing device 206. The content management device 205 performs storage management, copyright management, content identification, and detection work on real-time data. The content index device 207 searches for related content based on the content index keyword and the real-time content classification method by the real-time content processing device 206.

  The access control device 208 is connected to the content index device 207 and the distribution server 104. The access control device 208 performs authorization management for the distribution server 104, performs authentication for each received distribution access request, and realizes access control for real-time content. Only the authorized distribution server 104 is permitted to acquire the real-time content of the content server 103 via the content index device 207. The access control device 208 manages the access authority of the user and the access authority of the distribution server 104, and ensures that real-time information is provided only to authorized users and distribution servers.

  FIG. 3 is a block diagram for explaining the arrangement of distribution servers in the real-time system. The distribution server 104 processes the business request from the user and transmits real-time information from the content 103 to the end user. As shown in FIG. 3, the distribution server 104 includes a search job device 301, a customization job device 302, and a bulletin board device 303.

  The search service device 301 supports a search request for real-time information from a user. In this embodiment, the search service device 301 provides three types of search methods: geographic information search, content classification search, and content feature search. In the geographical information search, the user can acquire real-time information at a specific geographical position. Usually, a user searches real-time information using background coordinates and place name information, and acquires a real-time real-time scene at a specified geographical location. A user can connect to a camera at a designated location and observe traffic conditions, weather conditions or other real-time scenes. In content classification search, information search access based on the classification method is provided to the user. The user can search by inputting a keyword of his favorite content. By using the classification search, the user can quickly search for favorite news, entertainment or traffic information. In content feature search, a search result is provided to the user based on features of real-time information. This feature may typically be an image color feature, a human face parameter, or the like, or a video size and rate that can be supported by the mobile communication terminal. It is understood that the search methods that can be provided by the search service device 301 are not limited to the above three types, and other search methods, for example, a search method according to the name of the real-time content provider may be used. .

  The customization business device 302 can distribute the corresponding real-time information in the content server 103 to the user according to the customization request from the user without having to repeat the search request from the user. In the customization model, a user can send a specific real-time bill to the distribution server 104. If the real-time provider does not have the real-time content, the dynamic content collection method may be used to collect the necessary content for the user. Furthermore, the end user can customize the real-time content that can occur in the future. For example, the user may be interested in incidents that can occur in the next 1-2 hours. The user can customize viewing future possible incidents via a customization service.

  The bulletin board business device 303 provides hot information (for example, important public events, hot area traffic information, sudden incidents, etc.) to the user in the form of a bulletin board. The user can access the hot information using the bulletin board.

  Next, a flowchart in which the content server 103 acquires real-time information from a camera or a sensor will be described with reference to FIGS. 4 (a) and 4 (b). The content server 103 can collect real-time content by adopting a main collection or passive collection method.

  FIG. 4A shows a flowchart in which the content server 103 collects real-time content by the passive collection method. As shown in FIG. 4A, the cameras and sensors 101 and 102 transmit an access request to the content server 103 in order to provide real-time information to the content server 103. The content server 103 determines whether to agree to the subscription based on requests from the cameras and sensors 101 and 102. For example, the content server determines the authority of the camera or sensor that has transmitted the request, and if the content server has the access authority, permits the subscription by an access response message. Otherwise, access to the camera and sensors 101 and 102 is denied by an access response message. Note that if a plurality of imaging devices already provide raw information such as video at the same place, the content server 103 may not permit a new upload request. The camera or sensor that transmitted the request transmits real-time information to the content server 103 after obtaining permission from the content server.

  A specific process is as shown in FIG. In step S401, the camera / sensor transmits an access request to the content server 103 in order to provide real-time content in real time. After receiving the access request, the content server 103 determines whether to agree to the subscription. In step S <b> 402, the content server 103 transmits a response signal to the camera / sensor that has transmitted the access request to notify whether access to the content server 103 is permitted. If the access request is not permitted, the content server 103 does not need to transmit a response signal in order to save channel resources. In step S403, the camera / sensor that transmitted the access request receives the response signal from the content server 103, and then determines whether or not its request is permitted. If the request is not granted, the process ends. It should be noted that if the response signal is not received even if the time is exceeded, it is not permitted. When the response from the content server 103 indicates that the access request is permitted, the camera / sensor uploads the real-time content to the content server 103. The real-time content uploaded by the camera / sensor may include attribute information of the content.

  FIG. 4B shows a flowchart in which the content server 103 acquires real-time content by the main collection method. As shown in FIG. 4B, when the content server 103 attempts to collect real-time information of a specific area or specific content, first, a request message is broadcast in that area. If the movement in this area or the fixed camera / sensor agrees to upload real-time information, it registers with the content server 103 through a request response message. After determining the authority of the camera / sensor, the content server transmits an access request to the legitimate movement or the fixed camera / sensor via an access response message. These allowed movements and fixed cameras / sensors then transmit real-time information to the content server 103.

  Cameras / sensors can be automatically registered for user convenience. When the content server 103 transmits a request, the content server 103 checks in advance which users in the area are registered users, and transmits the request only to registered users. Therefore, registration is not necessarily a necessary procedure. Here, registration means that if the user wants to provide video content to the content server, it should be registered in advance in the content server. If it is not registered, video content cannot be provided to the content server.

  If the content server uses the registration information, there are at least the following advantages. All you need to do is send a request to a pre-registered user. As a result, network signaling is reduced (unregistered users cannot receive a request and therefore do not send a response message). On the other hand, the user who does not want to receive the request information is not disturbed. If the user registers, the provided content can be protected with better copyright.

  FIG. 4B shows a specific process in which the content server 103 mainly transmits a request to the camera / sensor and collects information mainly. In step S411, the content server 103 sends a request to the cameras / sensors 101 and 102 to invite uploading of the designated content in the designated area. If the camera / sensor agrees to access and provide real-time information after receiving the request, the camera / sensor transmits a request response to the content server 103 in step S412. After receiving the request response, the content server 103 determines whether to agree to the access of the camera / sensor. Even if the user agrees to subscribe in the request model, the content server may not allow access to some of the many users who agree to subscribe. When the content server 103 agrees to subscribe the user, the content server 103 transmits an access response in step S413. In step S 414, the camera / sensor permitted to access uploads real-time information to the content server 103.

  FIG. 5 illustrates an example in which the content server passively receives a request regarding real-time content upload from a user. Assume that a mobile user has witnessed a UFO. This user thinks that the case is worth the real time to the masses. And this user requests | requires provision of the said real-time content, for example, an image | video, with respect to the content server of a real-time system via a network. The attribute description of the real-time content is provided from the content provider to the content server. If the content server decides to accept the video real-time request of the UFO witness after receiving the request, the content server grants the access request and temporarily connects the UFO witness and the content server via the distribution server. And announce UFO real-time real-time information to the bulletin board business device. When the Internet or a mobile user reads the real-time news, it connects to the content server 103 and views the real-time UFO site. At this time, the content server officially connects the UFO video information to the distribution server and distributes it to the public.

  FIG. 6 is an example in which the content server mainly requests a mobile terminal user in a specific area to upload real-time content. When a content server wants to obtain real-time information in a specific area (for example, a sudden incident), if the content provider does not have a fixed camera installed in that area, the content server broadcasts it via a mobile network. Send a content upload request to the mobile communication terminal in the area. If the mobile communication terminal that has received the request can provide the real-time information desired by the content server, it uploads the real-time information to the content server as described in FIG. The distribution server provides the collected real-time real-time information to the end user using the bulletin board business device.

  FIG. 7 shows an example in which an end user searches his / her favorite real-time content using a search model. As shown in FIG. 7, the content server collects real-time information from the fixed camera / sensor and then stores it in a certain manner. When an end user wants specific real-time information (for example, real-time traffic conditions in a certain area or real-time scenery in a certain tourist area), the end user first transmits a search request to the distribution server. The distribution server searches the content server for related content and then transfers it to the end user.

  FIG. 8 shows an example of bulletin board type information distribution. As shown in FIG. 8, when a certain user wants to announce specific information (for example, a product presentation) to the outside, the real-time information collected by the mobile camera is uploaded to the content server via the mobile network. Then, the distribution server transfers the corresponding real-time information to the end user using the bulletin board. Or a delivery server transfers applicable real-time information based on a user's search request.

  Compared to the prior art real time system, the real world real time system of the present invention has the following advantages.

  1. Expansion of coverage. A conventional real-time system collects real-time content using a fixed imaging device and a static content collection method, and its coverage is very limited. For example, real-time monitoring of traffic conditions can only cover cities and hot areas, and its range is very small. In contrast, the present invention provides dynamic content collection, and any mobile user is a potential real-time content provider. Since mobile users are distributed all over the world, the present invention can provide an information collecting device covering the world. According to the real-time system of the present invention, Antarctic consideration scholars record scientific experiments on-site and deliver them to the real-time real-time system to provide real-time on-site response to demand for mobile and Internet users.

  2. More abundant content. Compared with the existing real-time system on the Internet, the conventional system provides the service to the user in a single subject system, and there are few types of content. For example, city traffic monitoring provides simple traffic information. The real-time content according to the present invention is more abundant, and if it is real-time information collected by an information collection / collection device such as a camera / sensor, it becomes the real-time content of the existing real-time system. For example, geographic information, incidents, persons, animals, scenery, etc. are all real-time contents of the existing real-time system. Compared with the conventional television real-time, the conventional television mainly performs real-time events that can be predicted, for example, sports matches. For sudden incidents, specialized reporters can often only arrive at the site for "second time". If the duration of the sudden incident is short, for example, only 10 minutes or 20 minutes, conventional real-time news can only be real-time as a result. However, because the present invention utilizes a dynamic content collection scheme, the entire process of the incident can be made real-time in real time, thus containing more rich content.

  3. Enhanced control model. Users in Google can collect cameras connected to networks around the world, but these cameras are controlled in a distributed manner by their respective owners. However, the real-time system in the real world can install a content server and a content distribution server to control and protect the content. First, a real-time content provider or content server according to the present invention can set attributes of uploaded content, and the content server can manage and control content distribution according to these content attributes. Next, an access control unit is installed in the content server, and the content cannot be distributed unless it is a content distribution server to which authority is given from the content server. This feature can efficiently protect the content of the content server.

  4). Flexible access method. In terms of access technology, a wireless system (for example, GSM, CDMA, UMTS, WLAN, etc.) and a wired system (for example, DSL, Cable, etc.) can both be user connection systems.

  5). Dynamic content collection. A conventional real-time system uses a fixed imaging device. However, the real-time real-time system of the present invention makes each mobile user a potential content provider by fully utilizing the features that mobile users are distributed in the world and mobile communication terminals have cameras. .

  6). Customize content and meet demand in real time. The user can request the customization of the specific content for the real-time real-time system, and the real-world real-time system of the present invention broadcasts this charge to other users according to demand. Other users can provide the necessary content in response to the request.

  7. Low cost cover. Since many mobile communication terminals have a photographing device, a real-time real-time system does not need to mount fixed cameras and sensors on a large scale, and can save network infrastructure costs.

  Real-world real-time systems meet the real-time demands of users for multimedia operations. The user can exchange the character, can be a business receptionist, and can be a business provider. The feature of character exchange according to the present invention will invite the active participation of many users. A user can obtain real-time real-time information provided from the system at any time as a business receptionist, which brings great convenience to daily life. You can enjoy the real-time program of real-time entertainment provided and have a more colorful life. On the other hand, if a user is a business provider and the uploaded content is popular from the Internet or mobile users, it will be enviable not only for the economic benefits it brings, but also for its success.

  Real-world real-time systems offer new operational models for fixed networks and mobile operators. In existing models, fixed Internet services are separated from mobile voice and multimedia services. Existing real-time systems basically provide and distribute content using the Internet or a dedicated network. The content is provided by almost fixed devices, such as fixed cameras and sensors. The present invention incorporates mobile networks and mobile users into the structure of the system. A mobile user becomes a content provider, and a mobile network becomes a carrier for content distribution. Real-world real-time systems make full use of the mobile network's control mechanism for mobile users, can quickly broadcast customized content requests, and can feed content mobile users back to meet content customization requirements. .

  So far, preferred embodiments of the present invention have been described. It should be understood by those skilled in the art that various modifications, replacements and additions can be made without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should not be understood as being limited to the specific embodiments described above, but is limited only by the scope of the appended claims.
