Description

Method for Transmitting / Receiving Weather Information of Satellite Broadcasting System {Method for Transmitting / Receiving Weather Information of Satellite Broadcasting System}

The present invention relates to a satellite broadcasting system, and more particularly to a method for transmitting and receiving weather information of a satellite broadcasting system.

Until now, satellite broadcasting systems have only been providing general A / V services, but in the coming multimedia era, the success or failure of the media will depend on how diverse and high quality services can be provided to consumers. As shown in FIG. 1, the schematic configuration of the satellite broadcasting system includes a program and a data signal source 1 which generates a broadcast related signal through various signal processing, and a program and data signal source 1 generated by the satellite broadcast system. A transmitting earth station (2), a resource and subscriber management system (RSMS) (3) for transmitting broadcast-related signals to satellites via satellites, and receiving and demodulating the broadcast signals transmitted from the satellites. To receive a limited number of broadcasts such as receivers (4) and paid programs to convert them into signals that viewers can watch And a smart card (6) in which viewing history is stored, a modem (7) for communicating with the RSMS (3), a Public Switched Data Network (PSDN) or a PSTN (communication network between the modem and the RSMS 3). It consists of Public Switched Telephone Network.

In this case, a signal multiplexed with video, audio, and additional information to be transmitted in a satellite broadcasting system is called a transport stream. Detailed information multiplexed by the transport stream is largely shown in FIG. 2. It is divided into Elementary Stream and Resource & Subscriber Management System (RSMS) stream. The elementary stream includes video information, audio information, and data added from digital broadcast. The main purpose for broadcast is the basic stream. The RSMS stream is side information.

In this case, the RSMS stream is divided into a service information (SI) and an RSMS message, of which SI is program specific information (PSI) and program guide information (PMM), which are program designation information for enabling the receiver to demultiplex TS. Guide Message (RSM) is divided into RSMS messages. Information is transmitted only when the CA is used. The RSMS message is divided into an Entitlement Control Message (ECM), an Entitlement Management Message (EMM), and a Receiver Command Message (RCM).

In addition, programs that are serviced through satellite broadcasting systems are required to use the smart card and pay the corresponding fee to pay for free channels such as KBS and MBC. -Per-View), PPC (Pay-Per-Channel), etc., the smart card (6) stores the history as much as watched and the contents of the service to charge the service fee for a certain period through a modem The center is sent to the RSMS 3.

Recently, various weather anomalies have occurred, and in particular, the tendency to occur by area is surprisingly strong. The best way to inform local residents of such extreme weather occurrences is to use broadcast media. Until now, weather information transmitted through broadcast stations is only available if the user turns on the receiver. Can be identified and countermeasures taken.

However, if the user does not turn on the receiver at night time, the weather information may not be known, and it may take time for the broadcasting station to broadcast the weather information of the meteorological agency, so that the viewer may receive the weather information quickly. There is a problem that cannot be obtained.

Accordingly, an object of the present invention is to provide a method for transmitting / receiving weather information of a satellite broadcasting system, which enables a viewer to quickly obtain local weather information regardless of an operation state of a receiver. There is this.

The present invention provides a satellite broadcasting system including a transmitter, a resource and subscriber management system (RSMS), and a receiver, the method comprising: allocating an address of each receiver and databaseting local information for each address; And storing and matching weather information of each region with the corresponding region information, and transmitting an RSMS message including the region weather information of each receiver together with the corresponding address.

The present invention relates to a satellite broadcasting system including a transmitter, a resource and subscriber management system (RSMS), and a receiver, wherein an RSMS message transmitted from the RSMS via a transmitter is received and an address set in the RSMS message matches its own address. An address judging step of judging whether or not, a message judging step of deciding whether or not the RSMS message is a weather information message by decoding the RSMS message if the address set in the RSMS message matches the address thereof; It is another feature that comprises the step of determining the class of the message and display on the screen corresponding to the class.

Hereinafter, a weather information transmission / reception method of a satellite broadcasting system according to the present invention will be described with reference to the accompanying drawings.

3 is a flowchart illustrating a method of receiving weather information of a satellite broadcasting receiver according to the present invention.

The satellite broadcasting system according to the present invention consists of a process of transmitting weather information in the RSMS (3) and receiving it in a satellite broadcasting receiver and outputting it to a viewer. First, a method of transmitting weather information in the RSMS (3) will be described. do.

RSMS (3) receives the urgent weather alert, ie local weather change situation, by assigning the receiver unique address for each subscriber, inputting the geographic location where the receiver is located in the database and connecting the database to the Meteorological Agency system. If the subscriber's area belongs to the weather report area, the RSMS message is transmitted as shown in Table 1.

At this time, the message class in Table 3 is to classify the display mode displayed on the receiver 4 of the subscriber according to the importance of the weather information, as shown in Table 4.

Rating volume Screen switching Repeated warnings duration On when receiver is off A 5 O 3 10 minutes O B 4 O 2 5 minutes X C 3 X One 3 minutes X

For example, if the grade of the weather information is 'A', the volume is set to '5' and is switched to the warning screen and programmed to generate three warning messages for 10 minutes, and the display operation is stopped by releasing the viewer.

Next, the process of receiving and displaying the transmitted RSMS message at the receiver will be described.

First, the receiver 4 receives an RSMS message having a format as shown in Table 1 (S11).

Subsequently, it is determined whether the address specified in the RSMS message and its own address match (S12), and if it matches, it is determined whether the received RSMS message is a weather information message (S13).

And if the determination result (S13), if the received RSMS message is a weather information message, the grade of the message included in the RSMS message is determined (S14).

Subsequently, as shown in Table 4, weather information is displayed on the screen so as to correspond to the corresponding message level (S15).

For example, if the message class is 'A' and the current receiver 4 is turned off, the receiver 4 is turned on and the corresponding weather information is displayed three times over 10 minutes.

That is, the message grade 'A' is a very urgent situation in which a flood, a typhoon, or the like has occurred in the region, so that the receiver 4 is turned on and the corresponding message is repeatedly displayed so that the viewer can be surely aware of it.

At this time, the pay broadcasting system maintains the operation state in order to grasp the viewing rate, so it receives the RSMS message regardless of the time and the on / off of the receiver 4 and 'turns on' the receiver 4 to display the corresponding weather information. You can do it.

In addition, since the above-described weather information is provided for each region, the viewer who owns the receiver 4 notifies the RSMS 3 of the location information when the geographical position of the receiver 4 owned by the user changes. Should update the database.

The weather information transmission / reception method of the satellite broadcasting system according to the present invention enables the viewer to identify and cope with local weather information regardless of the time and the operation state of the receiver according to its importance, thereby increasing user convenience. It works.
