본 발명은 일반전화교환망을 이용한 리턴 채널 구현방법에 관한 것으로, 특히 데이터 방송 수신기와 방송국 간에 일반전화교환망을 이용하여 리턴 채널을 구현함에 있어서, 그 신뢰성과 안정성을 향상시키는데 적당하도록 한 일반전화교환망을 이용한 리턴 채널 구현방법에 관한 것이다.The present invention relates to a method for implementing a return channel using a general switched telephone network, and more particularly, to implement a return channel using a general switched telephone network between a data broadcasting receiver and a broadcasting station, and to improve the reliability and stability thereof. It relates to a return channel implementation method used.

데이터 방송의 상용화에 따라 디지털 텔레비전을 이용한 홈쇼핑과 같은 텔레비전 방송은 소비자의 주문을 받기위해 쌍방향의 서비스 모델을 필요로 한다.With the commercialization of data broadcasting, television broadcasting, such as home shopping using digital television, requires an interactive service model in order to receive consumer orders.

통상 상기 쌍방향 서비스 모델의 구현을 위하여 리턴 채널(return channel)의 구현이 필수적이다.In general, the implementation of the return channel (return channel) is essential for the implementation of the interactive service model.

일반적으로, 상기 리턴 채널로는 일반전화교환망(PSTN)을 이용하며, 이와 같은 종래 일반전화교환망을 이용한 리턴 채널 구현방법을 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.In general, the return channel uses a general switched telephone network (PSTN), which will be described in detail with reference to the accompanying drawings.

도1은 종래 일반전화교환망(PSTN)을 이용한 리턴 채널 구현의 일실시 구성도로서, 이에 도시한 바와 같이 방송국의 카메라(1)를 통해 촬상된 방송신호는 중계국(2)을 통해 소비자의 텔레비전(3)에 수신된다.1 is a configuration diagram of an implementation of a return channel using a conventional public switched telephone network (PSTN). As shown in FIG. 1, a broadcast signal captured by a camera 1 of a broadcasting station is transmitted to a consumer's television through a relay station 2; 3) is received.

이때, 텔레비전(3)의 셋톱박스(4)는 일반전화교환망(PSTN)에 접속되어 방송국의 서버(5)에 연결된다.At this time, the set-top box 4 of the television 3 is connected to the PSTN and to the server 5 of the broadcasting station.

상기의 구성에서 소비자는 방송국에서 제공하는 홈쇼핑 방송을 보다가, 원하는 상품이 있는 경우 셋톱박스(4)를 조작하여 원하는 상품을 주문하며, 이 정보는 일반전화교환망(PSTN)을 통해 서버(5)에 인가되어 주문이 이루어진다.In the above configuration, the consumer views the home shopping broadcast provided by the broadcasting station and, if there is a desired product, operates the set-top box 4 to order the desired product, and this information is transmitted to the server 5 through the PSTN. The order is placed on the order.

그러나, 소비자가 셋톱박스(4)를 조작하여 서버(5)에 전화를 걸어 주문이 이루어지는 구성이므로, 연결이 지연되는 경우에는 원하는 제품을 주문할 수 없다.However, since the customer calls the server 5 by operating the set-top box 4, the order is made, and if the connection is delayed, the desired product cannot be ordered.

도2는 이와 같은 종래의 문제점을 가시화한 모식도로서, 이에 도시한 바와 같이 접속자의 수가 많은 경우 연결이 지연되어 주문을 하지 못하는 경우가 발생하며, 서버(5) 측에서는 연결이 지연되는 특정 셋톱박스(4)와의 연결을 거부하는 등의 문제점이 발생한다.FIG. 2 is a schematic diagram illustrating such a conventional problem. As shown in FIG. 2, when a large number of users is connected, a connection is delayed and an order cannot be generated. On the server 5 side, a specific set-top box ( Problems such as rejecting connection with 4) occur.

또한, 일반전화교환망(PSTN)의 특성상 보안이 이루어지지 않아 소비자의 정보등이 유출될 수 있다.In addition, due to the nature of the PSTN security is not made can be leaked consumer information.

그리고, 소비자가 홈쇼핑 방송으로 보고 전화를 걸어 서버(5)에 연결한 후, 주문이 이루어지므로 실시간 서비스가 정확하게 이루어지지 않는 문제점이 있었다.In addition, since the consumer makes a telephone call to the home shopping broadcast and connects to the server 5, the order is made and thus there is a problem that the real-time service is not made accurately.

이와 같은 문제점을 감안한 본 발명은 일반전화교환망의 사용량이 적은 시간대를 이용하여 리턴 채널을 구현할 수 있는 일반전화교환망을 이용한 리턴 채널 구현방법을 제공함에 그 목적이 있다.In view of the above problems, an object of the present invention is to provide a method for implementing a return channel using a general switched telephone network, which can implement a return channel using a time zone in which a general telephone switching network uses less time.

상기와 같은 목적을 달성하기 위한 본 발명은 홈쇼핑 방송의 진행과 동시에 구매의사정보를 전송하지 않고, 전화통화량이 적은 시간대에 예약을 통해 서버에 연결하여 구매의사를 전달하도록 구성됨을 그 특징으로 한다.The present invention for achieving the above object is characterized in that it is configured to transmit the purchase intention by connecting to the server through the reservation in the time of the telephone call volume without transmitting the purchase intention information at the same time as the progress of the home shopping broadcast.

도3은 본 발명 일반전화교환망을 이용한 리턴 채널 구현방법의 모식도로서, 이에 도시한 바와 같이 방송국의 카메라(1)로 촬상한 방송신호를 송출할때 현재 시간 정보를 함께 송출하는 단계와; 중계국(2)을 통해 전송된 현재 시간정보를 포함하는 방송신호를 수신하여 텔레비전(3)을 사용하여 수신하는 단계와; 상기 텔레비전(3)을 통해 방송을 시청하면서, 구매할 제품이 있으면 예약시간과 구매신청정보를 입력하는 단계와; 상기 구매신청정보를 저장한 셋톱박스(4)는 예약시간이 되면 전화연결을 통해 방송국의 서버(5)에 구매신청정보를 전송하는 단계로 이루어진다.FIG. 3 is a schematic diagram of a method for implementing a return channel using a general telephone switching network of the present invention, including transmitting current time information when transmitting a broadcast signal captured by a camera 1 of a broadcasting station as shown in FIG. Receiving a broadcast signal including current time information transmitted through the relay station 2 and using the television 3; Inputting a reservation time and purchase application information if there is a product to purchase while watching a broadcast through the television (3); The set-top box 4 storing the purchase request information consists of transmitting the purchase request information to the server 5 of the broadcasting station through a telephone connection when the reservation time comes.

이하, 상기와 같은 본 발명의 일실시예를 보다 상세히 설명한다.Hereinafter, an embodiment of the present invention as described above will be described in more detail.

먼저, 방송국의 카메라(1)를 통해 촬상한 홈쇼핑 방송의 방송신호는 중계국(2)을 통해 소비자의 텔레비전(3)에 수신된다.First, the broadcast signal of the home shopping broadcast captured by the camera 1 of the broadcasting station is received by the television 3 of the consumer via the relay station 2.

이때 홈쇼핑 방송신호는 방송의 현재 시각을 포함한다.At this time, the home shopping broadcast signal includes a current time of broadcasting.

상기의 예에서는 오후 3시(15:00)에 촬상된 방송임을 나타낸다.In the above example, the broadcast is captured at 3 pm (15:00).

상기의 홈쇼핑 방송을 텔레비전(3)을 통해 시청하는 소비자는 구입을 원하는 제품이 있는 경우, 셋톱박스(4)를 조작하여 구매신청정보를 입력하고, 예약시간을 설정한다.The consumer who views the home shopping broadcast through the television 3, if there is a product he wants to purchase, operates the set top box 4 to input purchase application information and sets a reservation time.

즉, 구입할 제품의 소비자의 카드정보, 배송지 주소등을 입력하며, 이 구매신청정보는 셋톱박스(4) 내에 저장된다.That is, the card information, the shipping address, etc. of the consumer of the product to be purchased are input, and the purchase application information is stored in the set top box 4.

셋톱박스(4)는 현재시간(15:00)과 예약된 시간(03:00)을 비교하여, 현재시간이 경과하여 현재시간과 예약시간이 동일한 시간(03:00)이 되면, 일반전화교환망(PSTN)을 통해 전화를 걸어 상기 서버(5)에 연결한다.The set-top box 4 compares the current time (15:00) with the reserved time (03:00). When the current time passes and the current time and the reserved time are the same time (03:00), the general telephone exchange network Make a call via PSTN to connect to the server 5.

이때, 예약시간은 전화통화가 많지 않은 새벽 시간대이며, 이로 인해 전화의 폭주에 의한 연결의 지연을 방지할 수 있게 된다.At this time, the reservation time is the dawn time when there are not many telephone calls, thereby preventing the delay of the connection due to the congestion of the telephones.

도4는 본 발명의 다른 실시예의 모식도로서, 이에 도시한 바와 같이 방송국에서 홈쇼핑 방송을 송출하면서, 현재시간 뿐만 아니라 예약시간 정보를 함께 송출하는 것으로, 현재시간이 15:00이고, 예약 시간이 00:00로 설정된 경우를 도시하였다.4 is a schematic diagram of another embodiment of the present invention. As shown in FIG. 4, the home station broadcasts the home shopping broadcast and transmits the reservation time information as well as the current time. The present time is 15:00 and the reservation time is 00. The case set to: 00 is shown.

이처럼 방송국에서 직접 예약시간을 설정하여 방송신호와 함께 송출하면, 소비자가 제품을 구매하기 위하여, 구매신청을 하는 경우, 셋톱박스(4)에서는 구매신청정보를 저장하고 있다가 상기 예약시간이 되면 서버(5)에 전화를 걸어 연결하고, 상기 구매신청정보를 전송한다.In this way, when a broadcast station sets a reservation time directly and transmits it with a broadcast signal, when a consumer requests a purchase in order to purchase a product, the set-top box 4 stores the purchase request information and then the server reaches the reservation time. (5) call to connect, and transmit the purchase application information.

이와 같은 방법을 사용하면, 소비자는 예약 시간을 설정할 필요없이 구매신청정보만을 입력하여 지정된 시간이 되면 필요한 물품을 주문할 수 있게 된다.Using this method, the consumer can input only the purchase application information without having to set a reservation time and order the necessary goods at the designated time.

도5는 상기의 과정을 상세하게 기재한 본 발명 일반전화교환망을 이용한 리턴 채널 구현방법의 순서도로서, 이에 도시한 바와 같이 텔레비전 화면에 홈쇼핑 방송이 표시됨과 아울러 쌍방향 서비스가 가능하다는 컨텐츠가 표시되는 단계와; 소비자가 구매하고자 하는 제품을 리모트 콘트롤러를 사용하여 지정하고, 방송국으로 보낼 구매신청정보를 입력시키고, 저장하는 단계와; 상기 방송신호에 예약시간 정보가 포함되어 있는가를 판단하는 단계와; 상기 판단의 결과 예약시간정보가 없으면 사용자가 예약 시간을 입력하는 단계와; 상기 판단의 결과 예약시간정보가 있으면 그 예약시간정보를 저장하는 단계와; 상기 예약시간이 되었는지 주기적으로 판단하여 예약시간이 되지 않았으면 대기하는 단계와; 상기 예약시간이 되었으면 셋톱박스에서 전화선을 통해 방송국 서버에 접속을 시도하는 단계와; 방송국 서버에 접속되었는지 판단하여 접속되지 않았으면, 상기 접속시도를 계속 수행하고, 접속되었으면 상기 저장된 구매신청정보를 방송국 서버로 전송하고 종료하는 단계로이루어진다.FIG. 5 is a flowchart illustrating a method for implementing a return channel using a general telephone switching network of the present invention, which describes the above-described process in detail, in which a home shopping broadcast is displayed on a television screen and contents indicating that interactive services are available. Wow; Designating a product to be purchased by a consumer using a remote controller, inputting and storing purchase request information to be transmitted to a broadcasting station; Determining whether reservation time information is included in the broadcast signal; Inputting a reservation time by the user if there is no reservation time information as a result of the determination; Storing the reservation time information if the reservation time information exists as a result of the determination; Periodically determining whether the reservation time is reached and waiting if the reservation time is not reached; Attempting to connect to a broadcasting station server through a telephone line in the set top box when the reservation time is reached; If it is determined that the user is connected to the broadcasting station server and not connected, the connection attempt is continued. If the connection is established, the stored purchase request information is transmitted to the broadcasting station server and terminated.

이하, 상기와 같은 본 발명을 보다 상세하게 설명한다.Hereinafter, the present invention as described above will be described in more detail.

먼저, 방송국의 방송신호를 전송받은 텔레비전은 화면에 홈쇼핑 방송을 표시한다. 이때 소비자에게 쌍방향 서비스가 가능하다는 것도 함께 표시한다.First, a television receiving a broadcast signal from a broadcasting station displays a home shopping broadcast on a screen. At this time, the interactive service is also displayed to the consumer.

상기 방송신호에는 상기 도3과 도4의 예에서와 같이 현재시간정보가 포함되어 있으며, 선택적으로 예약시간정보가 포함될 수 있다.The broadcast signal includes current time information as in the examples of FIGS. 3 and 4, and may optionally include reserved time information.

그 다음, 상기 텔레비전을 통해 홈쇼핑 방송을 시청하던 소비자가 구매하고자 하는 제품이 있을때, 그 제품을 구매하기 위한 구매신청정보를 리모트 콘트롤러를 사용하여 셋톱박스에 저장시킨다.Then, when there is a product that the consumer who is watching the home shopping broadcast through the television wants to purchase, the purchase application information for purchasing the product is stored in the set top box using the remote controller.

그 다음, 상기 셋톱박스는 수신되는 방송신호에 예약시간정보가 포함되어 있는지 판단한다.Next, the set top box determines whether the reservation time information is included in the received broadcast signal.

상기의 판단결과 예약시간정보가 있으면 그 예약시간정보가 지정하는 시간을 예약시간으로 지정하고, 예약시간정보가 없으면 소비자에게 예약시간정보를 입력하도록 인지시킨다.As a result of the determination, if the reservation time information exists, the time designated by the reservation time information is designated as the reservation time, and if there is no reservation time information, the consumer is prompted to input the reservation time information.

소비자가 상기 예약시간을 입력하면 이를 예약시간으로 지정하여 저장한다.If a consumer inputs the reservation time, it is designated as a reservation time and stored.

그 다음, 상기 셋톱박스는 상기 예약시간과 현재시간을 주기적으로 비교한다.The set top box then periodically compares the reservation time with the current time.

이때 예약시간과 현재시간이 서로 다르면 대기상태로 있으며, 예약시간과 현재시간이 같아지면 일반전화교환망을 통해 전화를 걸어 방송국 서버에 접속을 시도한다.At this time, if the reservation time is different from the current time, it is in a standby state. If the reservation time and the current time are the same, it makes a call through the general telephone exchange network and attempts to connect to the broadcasting station server.

그 다음, 방송국 서버와 연결되었는지 판단하여, 상기 서버에 접속되지 않았으면 상기 방송국 서버와의 접속을 자동으로 재시도하고, 상기 방송국 서버와 연결되었으면 저장된 구매신청정보를 방송국 서버로 전송하여, 구매신청을 한다.Then, it is determined whether it is connected to the broadcasting station server, and automatically retries the connection with the broadcasting station server if not connected to the server, and if the connection is made with the broadcasting station server, the stored purchase application information is transmitted to the broadcasting station server to make a purchase request. Do it.

이와 같이 구매신청정보를 전송한 후에는 방송국 서버와의 연결을 해제한다.After the purchase request information is transmitted in this way, the connection with the broadcasting station server is released.

상기한 바와 같이 본 발명은 일반전화교환망을 이용하여 리턴 채널을 구현함에 있어서, 홈쇼핑 방송이 진행되는 전화 사용량이 많은 시간에 리턴 채널을 사용하지 않고, 시간을 미리 설정하여 전화 사용량이 적은 시간에 방송국 서버에 접속함으로써, 서버에 접속의 폭주에 의해 접속이 차단되거나, 연결이 되지 않는 현상을 방지할 수 있는 효과가 있다.As described above, the present invention implements a return channel using a general telephone switching network, and does not use a return channel at a time when the home shopping broadcast is busy. By connecting to the server, there is an effect that can prevent the phenomenon that the connection is blocked or disconnected due to congestion of the connection to the server.

또한, 심야시간을 예약하여 구매정보를 전송함으로써 전화요금의 심야할인을 이용하여 비용을 절감하는 효과가 있다.In addition, by reserving the late night time to transmit the purchase information it is effective to reduce the cost by using the late night discount of the telephone bill.
