Digital Satellite Broadcasting E-Mail Receiver and E-Mail Receiving Method

The present invention relates to a satellite broadcasting system having an e-mail receiving function. In particular, the satellite broadcasting system exchanges messages from a subscriber management system using a modem of a satellite broadcasting receiver without a viewer setting up the Internet environment. The present invention relates to a digital satellite broadcasting E-mail receiver and an E-mail receiving method capable of receiving an E-mail.

In general, the interface between the structure of the DBS system and the receiver sends a signal source of program and data to the transmitting earth station 1 as shown in FIG. 1, and also to the resource and subscriber management system (RSMS) 2 to manage subscribers. The system transmits PSI information, that is, subscriber management information and various kinds of information, to the transmitting earth station 1.

It is transmitted from the transmitting earth station 1 to the various receivers 4 through the Mugunghwa satellite 3 so that video and audio are output through the NTSC TV 5 or the VCR 6 so that the user can watch.

When the information is PAY-PER-VIEW, the audio packet and the video packet are scrambled, so that the subscriber purchases a smart card 7 and the resource and subscriber management system 2 The scramble could be removed by receiving the message of the transmitting resource and subscriber management.

In addition, the receiver 4 checks the usage of the smart card by incorporating a modem to access the resource and subscriber management system 2 through the PSTN / PSDN 8.

The RSMS stream of the transmitted transport packet is composed of an address, a Fcode, an APPMSG (Application Message), and an FCS (Frame Check Sequence), in which a payload part is a service reception signal, so that the receiver 4 manages resources and subscribers. When receiving the message of the receiver 4 compares the address (ADDR) of the corresponding address in the receiver 4, if the address belonging to the receiver 4, using the APPMSG to smarten the usage record required by the resource and subscriber management system (2) Read from card 7 and send.

Meanwhile, FIG. 2 shows a sequence between a smart card 7, a receiver 4, a resource, and a subscriber management system 2 in which a procedure of transmitting a subscriber usage record is shown.

First, when the receiver 4 receives a usage request message from the resource and subscriber management system 2 (step 10), it requests a connection using a PSDN * 25 network through a modem to a telephone number in APPMSG (step 10). 11).

If the connection is successful (step 13) by requesting the connection of the resource and subscriber management system 2 (step 12), the receiver 4 transmits a call connection ENQ message every two seconds (step 14). The management system 2 transmits until the call connection ANK is made (step 15).

If the transmission of the call connection ENQ message of the receiver 4 succeeds, after receiving the usage record request message from the resource and subscriber management system 2 (step 16), the smart card 7 dials up the usage to receive the usage amount. Read the information and report the usage record to the resource and subscriber management system 2 (step 17).

In addition, in order to update as much as the information used by the smart card (7), it is erased by the amount of usage so that the receiver (4) receives a response from the smart card (7) and the resource and subscriber management system (2) reports the usage record (erasing) (Step 18).

When the resource and subscriber management system 2 confirms record erasure after requesting record erasure (step 19), the receiver 4 checks the short circuit of the call and transmits a message (step 20).

However, in the above hypocrisy broadcasting system, a user who pays a fee by paying scrambled pay channel programs to record pay information through a smart card, and removes scrambled signals and voices while paying the fee. As a user can see, there is a disadvantage in that messages are transmitted and received to the resource and subscriber management system only through a modem.

Accordingly, the present invention provides a digital satellite broadcasting E-mail which enables a viewer to receive a message exchange and E-mail from a subscriber management system using a modem of a satellite broadcasting receiver in a digital satellite broadcasting system without an Internet environment. It is intended to provide a Mail receiver.
