In "a real-time Internet broadcasting system" (patent certificate number: 089607) proposed by E-info, the structure diagram is shown in FIG. It is known that the conventional data collection and processing device 100 is used to collect data transmitted by the information source W103, information source X104, information source Y105, and information source Z106, and collect and process the received information according to the arrival data The time of the device 100 is serialized and stored in the memory. The user authentication device 130 is then used to confirm the identity of the user and accept the type of information requested by the user. The client-side information receiving device 12 is used to receive the type of information that the user wants to receive, and can check the unreceived information. The multicast device 110 is used to obtain information transmitted by all connected information sources, and to know the network address of the client-side information receiving device 120, which is equal to the type of information to be received and the information that is missed. Give it away. In this conventional system, although the purpose of sending information to the client can be achieved, several shortcomings are revealed as follows: I. Between the client information receiving device and the multicast device, only one-way transmission can be performed during the information transmission Data, which means that clients cannot change the type of information they want to receive online in real time. 2. Its multicast device not only transmits real-time information to the client, but also retransmits the missing data, which easily causes the delay of real-time information to reach other clients. 06778twfl doc / 006 Date of revision 92 10 17 3. After receiving the real-time information, the multicast device not only sends it to the client, but also needs to store a copy of the data in the directory, which causes an increase in system load. The effect of hardware input / output device speed 'cannot send information in real time in the shortest time. 4. Its multi-point transmission device, when transmitting information, cannot confirm that it will be able to send out information within a certain period of time, which is likely to involve other clients due to the complex Internet environment or the poor quality of a single client connection, resulting in Instant messaging is no longer instant. Because the conventional data transmission method is UDP, the TCP method is used only when resending missing information. However, the UDP protocol cannot guarantee that the information can be delivered. Therefore, the phenomenon of missing information is prone to occur. When using TCP to supplement the data, this data has been delayed and is not delivered immediately. 5. It is explained that the information is transmitted at a fixed time (t). Through this method, four separate packets can be transmitted at a fixed point in time, which can improve the bandwidth usage. But in fact, the contents of the four packets must be transmitted. As a result of the delay, the total amount of data has not decreased, only the number of packets has been reduced. It does not help with the use of bandwidth, but it delays the delivery of information, that is, it is not really real-time information. In addition, because the information accumulated during that time is transmitted at a fixed time, it is easy to cause instant congestion on the network, because the information scattered at time t is collected and transmitted at the same time. In view of this, the present invention proposes an information pre-processor and an information real-time playing system and method using the same. The difference from the conventional one lies in that the present invention transmits data in In-Time mode instead of Real-56460. #, v Revise date 92 10 17 06778twfl doc / 006

In addition to the above-mentioned necessary elements, the present invention further includes: a buffer zone, an instant monitoring system, and a load balancing system. Among them, the buffer exists in the hierarchical real-time playback system, and is one-to-one corresponding to the information playback host. When the information playback host has an information packet that cannot be transmitted temporarily, the information packet is temporarily stored in the buffer first. Zone, and then process the next client without delaying the transmission of information packets. The real-time monitoring system is used to monitor the buffer, and whether there is enough space to store information packets. The load balancing system is coupled between the information playback host and the information receiving end. It is used to determine whether each information receiving end can be connected to the information playback host with a lower load. In this hierarchical real-time playback system, we can divide the information playback host into the first layer information playback host and the second layer information playback host. The first layer of information playback host here is used to receive and mix the encoded and identified information packets, that is, it will receive and mix the information packets sent from the information preprocessor. The second-level information playback host sends the information packets sent by the first-level information playback host to the information receiving end, and stores the information packets that cannot be transmitted temporarily in the buffer area corresponding to the information receiving end. The present invention also proposes an information pre-processor for receiving and processing information sources. The information preprocessor includes: an information encoding program, which performs encoding on the information packet transmitted by the information source of 7 doc / 006 IE date 92.10 Π. The so-called encoding action is to uniformly compile the received information packets with any data type into a new data type. The channel identification processing program is coupled to the information encoding program and adds a hierarchical channel identification code to each different information packet. Among them, the hierarchical channel identification code is used to classify and subclass data packets. The present invention also proposes a method for subscribing to real-time information, which is a method for a client to subscribe to real-time information to a preset information playback host. The steps of this method of subscribing to real-time information include: a load balancing system will first determine whether the default information playback host can load the workload of this client. If the default information playback host cannot load the client, the client is allowed to subscribe to real-time information; but if the default information playback host cannot load the client, then another information playback host with a low load is assigned to this Client connection. The method of subscribing to the real-time information method further includes: the client will first connect to the default information playback host, and then if the information playback host can load the client, the information playback host will determine whether the client has permission to subscribe Real-time information. If this client does not have permission ', it is determined that this client connection fails, if this client has permission, it is determined that this client connection is successful. The present invention further proposes a method for real-time information broadcast, which relates to an information real-time broadcast system that transmits the received real-time information 'to a plurality of clients. The steps of this information real-time playback method include: · Performing encoding operations on the received real-time information 06778twfl.doc / 006 correction date 92 10 17 message. Next, add the channel identifier to the encoded real-time information. Then, the coded and identified real-time information is mixed, and the mixed real-time information is passed to the client. If the client cannot immediately receive the real-time information, the real-time information is stored in the buffer to which the client belongs. Among them, the method of real-time information playback method further includes: firstly determining whether there is a client subscribing to the information channel; if there is no client subscribing to the information channel, the transmission of the real-time information is ended, otherwise it continues to determine whether there are unprocessed clients. If there is an unprocessed client, select any one of the unreceived clients. If there is no client to be processed, then the sending of the real-time information ends. When the client can receive the real-time information immediately, the real-time information is transmitted to the client. The present invention further provides a pre-processing information method, which relates to a method for processing the received real-time information by the information real-time playing system. The previous method of processing information includes performing encoding on the received real-time information, and then adding a channel identification code to the real-time information. The present invention also proposes a method for real-time information broadcast, which relates to a method for the information real-time broadcast system to transmit the received real-time information to multiple clients. The steps of this method of real-time information playback include: first mixing the coded and recognized real-time information, and then transmitting this real-time information to the client. If the useful client cannot immediately receive the real-time information, the real-time information is stored in the buffer to which the client belongs.

Steps s500 to s520 are another implementation of the present invention. ML Please refer to FIG. 2, which shows a method according to a preferred embodiment of the present invention. The information real-time playing system is about transmitting the information packet received by the information source to the client through the Internet. This information real-time playback system includes: information pre-processors 206, 208, and 210, hierarchical real-time playback system 212, information playback hosts 214, 216, 218, and 220, and information receiving ends 230, 232, and 234. Among them, the information pre-processors 206, 208, and 210 are used to collect multiple information sources, such as information sources 200, 202, and 204; perform encoding operations on the information packets transmitted by these information sources; for each different Information packet plus hierarchical Channel ID. The requested encoding action is to uniformly compile the received information packets with any data type into a new data type. That is to say, regardless of whether the received information source is binary data or text data, the information packets transmitted by the information sources 200, 202, and 204 can be uniformly compiled into this document through encoding operations. The type of data that can be recognized in the system. And this purpose is to make the information provider need not worry about the information source he provided, because it is mixed with other information sources in the same system, and there is a fear of being intercepted by others. Allows information providers to transfer information into this system with peace of mind, 11 5,64609 06778twfl doc / 006 revision date 92 10 17 and information receiving end 230, 232 and 234 can only receive information when there are certain specific programs Packet. Among them, if an information source collects information about the stock market, it will correspond to an information preprocessor, and if an information source collects information about the image, it will also correspond to an information preprocessor, and so on, that is, Saying that different information sources correspond to different information preprocessors. After encoding the information packets sent by the information source, a hierarchical channel ID is added to these information packets. This hierarchical channel ID will classify the information packets into a large category. "Sub-classification" For example, when the received information source is [Music Type] In-Time Message, the received music information is first classified into classical or modern music. If it is classical music, it is again targeted at This music information judges which era under classical music or which musician created it, and classifies this music information. The hierarchical real-time playback system 212 is connected to the information pre-processors 200, 202, and 204. In this hierarchical real-time playback system 212, there are multiple information playback hosts, such as information playback hosts 214, 216, 218, and 220. The message playback host exists in the hierarchical real-time playback system 212 with a hierarchical structure. It receives the information packets transmitted by the information pre-processors 206, 208, and 210, and in-time, The message packet is sent to a client with permission to receive it. As far as this embodiment is concerned, although it seems that an information playback host corresponds to one information receiver, in reality, it is one information playback host that corresponds to thousands of information receivers. Among them, in the hierarchical real-time playback system 212, 12 564609 06778twfl doc / 006 correction date 92 10 17 can be duplicated to add another information playback host 214, 216, 218, and 220. The hierarchical real-time playback system 212 replicates the information playback host. As shown in FIG. 6, the entire structure of the information playback hosts 214, 216, 218, and 220 that already exists in the hierarchical real-time playback system 212 is used to replicate the entire information. The playback host, or as shown in FIG. 7, uses a hierarchical structure to replicate the information playback hosts 216, 218, and 220. This refers to the information transmitted within a certain period of time, which means that we can use the real-time monitoring system 236 that can monitor the buffer area to avoid encountering poor information quality receiving end when transmitting using the TCP protocol. , And the delay problem is achieved, so that the information can be quickly sent to all the information receivers without being affected by the information receivers, thereby ensuring that a single information playback host can send information to up to hundreds of milliseconds. Thousands of information receivers. The information receiving terminals 230, 232, and 234 are connected to the hierarchical real-time playback system 212, and are used to receive information packets transmitted by the information playback hosts 216, 218, and 220, and allow the client to change the information source it wants to receive at any time. kind. The information playback hosts 216, 218, and 220 and the information receivers 230, 232, and 234 use a connection control protocol to transmit the information packets, and the transmission control protocol is (Transmission Control Protocol; TCP for short), this transmission method can ensure that the data transmitted by the system will not be missed. In addition to the necessary components described above, this embodiment further includes: buffers 222, 224, and 226, an instant monitoring system 236, and a load balancing system (not shown in the figure). 13 $ 646¾ 06778twfl doc / 006 Date of revision 92 10 17 Among them, the buffer areas 222, 224, and 2% exist in the hierarchical real-time playback system 212, and are connected to the information playback hosts 220, 218, and 216, respectively-corresponding connections When the information playback hosts 220, 218, and 216 have information packets that cannot be transmitted temporarily, the information packets will be temporarily stored in the buffers 222, 224, and 226 first. The real-time monitoring system 236 is used to monitor the buffers 222, 224, 226, and whether there is sufficient space to store information packets. The purpose of this real-time monitoring system 236 is to improve the lack of the above TCP connection method, because if it is Due to the poor connection status of TCP itself, information packets must be resent, and subsequent information packet transmission is delayed. You can observe the connection of the client by monitoring the system 236 in real time and monitoring the actions of the buffers 222, 224, and 226. Quality to determine whether to send the information packet to the information receiving end 230, 232, and 234 immediately, or to temporarily store it in the buffers 226, 224, and 222 of the client. In this way, it can be ensured that the information packet will not be missed in the transmission process, no retransmission is necessary, and the purpose of immediate transmission can be achieved. In this way, the time of the system's information packet can be reduced to the unit of time transmission in milliseconds (mini second). The load balancing system is coupled between the information playback hosts 220, 218, and 216 and the information receiving ends 230, 232, and 234. It is used to determine whether each information receiving end is assigned to the information playback host. Among them, the information playback host allocated to the information receiving end 230, 232, 234 may be the information playback host 220, 218, 216 already existing in the hierarchical real-time playback system 212, or a newly added information playback host. In this hierarchical real-time playback system 212, we can divide the information playback host into the first layer information playback host 2M and the second layer information playback host 22〇, 14 56460 ^ Revised date 92 10 17 06778twfl doc / 006 218, 216 . The first-level information playback host 214 is used to receive and mix the encoded and identified information packets, that is, it will receive and mix the information packets transmitted from the information pre-processors 206, 208, and 210. The second-level information playback host 220, 218, and 216 sends the information packets sent by the first-level information playback host 214 to the information receivers 230, 232, and 234, and stores the information packets that cannot be sent temporarily. The buffers 226, 224, and 222 corresponding to the information receiving ends 230, 232, and 234. Please refer to FIG. 3, which shows an information preprocessor according to another preferred embodiment of the present invention, which is used for receiving and processing information sources. The information pre-processor includes: an information encoding program 300, which performs an encoding operation on an information packet transmitted by the information source 300. The so-called coding action is to uniformly compile the received information packets with any data type into a new data type. The channel identification processing program 302 is coupled to the information coding program 300, and adds a hierarchical channel identification code to each different information packet. Among them, the hierarchical channel identifier is used to classify and subclass data packets. Please refer to FIG. 4, which illustrates a method for subscribing to real-time information according to yet another preferred embodiment of the present invention, which is a method for a client to subscribe to real-time information to a preset information playback host. The steps of this method for subscribing to real-time information include: the load balancing system first determines in step s402 that the preset information playback host is the load of the client of Xiang Ke. If the default information playback host cannot load the client, then in step s406, the client is accepted to subscribe to the instant message; but if the default information playback host cannot load the client, then step s4. 8 out of 15

The steps of the method for subscribing to the real-time information further include: the client will first connect to the default information playback host in step S400. If the information broadcasting host can load the client, then in step S404, it is determined whether the client has permission to subscribe to the real-time information. If in step S404, the client does not have permission, then in step S410, it is determined that the connection of the client has failed. If the client has permission, it is determined that the connection of the client is successful. Please refer to FIG. 5, which illustrates a method for real-time information playback according to yet another preferred embodiment of the present invention, which is related to an information real-time playback system transmitting real-time information received to multiple clients. The steps of this method for real-time information playback include: Step s500 ′, perform coding on the received real-time information. Next, in step s502, a channel identification code is added to the encoded real-time information. Then, in step s504, the coded and identified real-time information is mixed, and in step s506, the mixed real-time information is transmitted to the client. When the real-time information is transmitted to the client, if in step s516, there is When the client cannot receive real-time information immediately, in step S520, the real-time information is stored in a buffer to which the client belongs. Among them, the method of real-time information playing method further includes: first determining whether a client subscribes to the information channel in step S508, and if no client subscribes to the information channel in step S508, proceed to step S512 to end the transmission of real-time information Otherwise, continue to step S510 to determine whether there is an unprocessed client. If in step s510, there are “unprocessed clients”, then in step S514, select any user that has not received this instant information 16 doc / 006 correction date 92 10 17 terminal, otherwise proceed to step S5 〖2, End sending instant messages. When the client can immediately receive the real-time information in step s5l4, the real-time information is transmitted to the client in step s518. Then return to step s510 and repeat the above steps until no client needs to receive this real-time information. Please refer to FIG. 5 again, which illustrates a pre-processing information method according to yet another preferred embodiment of the present invention, which is related to the information real-time playback system processing the received real-time information. This method of processing information includes: Step s500, performing a coding operation on the received real-time information. The so-called coding operation is to receive an information packet of any type of data, and compose it into a data packet. Only the real-time playback system becomes a new type of data that is recognized. Then, in step s02, a channel identification code is added to this real-time information. Among them, the hierarchical channel identification code is used to classify the packet. Makes the _ instant playback system easy to manage the received instant information. Please refer to FIG. 5 again, which shows another method of -___ prostitutes according to the present invention, which is a method for real-time information broadcasting system to receive the user terminals in the county. The steps of this method of real-time playing of information include: first, in step _, mix the coded and identified real-time _, step _4, and pass this real-time information client. If in Step 16 the front-end client cannot immediately receive the real-time time, the job step is called, and the time-of-day information is stored in the buffer to which the client belongs. In summary, the advantages of the present invention include: 564609 06778twfl doc / 006 Date of revision 92.10.17 1. The real-time information delivered is an In-Time Message, which is different from the conventional Real-Time Message: it can be confirmed within a certain time Send information to the client. For client connections with poor connection quality, the information playback host will abandon this client connection when it confirms that the information packet cannot be delivered within a certain period of time to ensure that other clients can Enjoy a certain quality of instant messaging. 2. Encoding action: It enables the information playback host to process information of various types of data, and also protects the information content provided by the information provider from being obtained improperly. 3. The information receiving end and the information playing host adopt a two-way communication interface: the client can change the type of information channel subscribed at the same time when the system transmits real-time information. 4. The information broadcast host does not save the information packets received from the information source: it immediately sends the received information packets to the clients subscribing to this channel information to ensure that the information is immediately sent to user terminal. Although the present invention has been disclosed in the preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and retouches without departing from the spirit and scope of the present invention. Therefore, the present invention The scope of protection shall be determined by the scope of the attached patent application. 18
