Description

셋톱 박스의 채널 정보 수신 방법 { Method receiving channel data of set top box }Method of receiving channel information of set top box {Method receiving channel data of set top box}

본 발명은 셋톱 박스의 채널 정보 수신 방법에 관한 것으로서, 특히 복수개의 위성으로부터 채널 정보를 수신할 때 복수개의 위성에 순서를 부여하여 그 순서에 따라 각 위성을 탐색하고 그에 해당하는 채널 정보를 수신하는 과정을 자동으로 수행하는 셋톱 박스의 채널 정보 수신 방법에 관한 것이다.The present invention relates to a method for receiving channel information of a set-top box. In particular, when receiving channel information from a plurality of satellites, the plurality of satellites are assigned an order to search for each satellite according to the order and receive the corresponding channel information. The present invention relates to a method for receiving channel information of a set-top box that automatically performs a process.

일반적으로 위성 방송은 지구로부터 35,784Km 상공에 위치한 방송 위성을 이용해 텔레비젼이나 라디오 방송등을 하는 것을 말하고, 위성 방송은 일반 공중에 방송이 직접 수신되도록 하기 위한 것으로 인공위성에 탑재된 우주국에 의해 신호를 전송 또는 재송신하는 방송 방식이다.In general, satellite broadcasting refers to TV or radio broadcasting using a broadcasting satellite located 35,784 km above the earth. Satellite broadcasting is to receive broadcasts directly to the general public and transmit signals by space stations mounted on satellites. Or retransmission.

이러한 위성 방송은 위성으로부터 위성 안테나로 직접 전파를 송신하기 때문에 화질의 첨화가 적어 화상이 깨끗하며, MPEC-2를 이용한 다중화 방식 및 QPSK 변조방식을 이용하기 때문에 고음질이 가능하고, 위성을 중계 매체로 하기 때문에 자연 또는 전쟁등의 피해를 입지 않고 긴급시에 전국에 일제히 방송이 가능하다.Since satellite broadcasting transmits radio waves directly from satellites to satellite antennas, the picture quality is clear because the picture quality is low, and the high quality is possible because it uses the multiplexing method and the QPSK modulation method using MPEC-2. Therefore, it is possible to broadcast all over the country at the time of emergency without being damaged by nature or war.

한편, 상기 위성 방송을 수신할 수 있는 셋톱 박스에는 사용자로 하여금 수신되는 방송의 채널 정보를 확인할 수 있고, 방송의 시청 및 청취에 대한 기능 선택 및 설정과 사용자의 편의에 관한 옵션을 조정할 수 있도록 GUI(Graphic User Interface)형태의 메뉴 화면을 제공한다.On the other hand, the set-top box that can receive the satellite broadcasts GUI to allow the user to check the channel information of the received broadcast, and to adjust the function selection and settings for viewing and listening to the broadcast and the user convenience options Provides a menu screen in the form of (Graphic User Interface).

종래의 기술에 따른 셋톱 박스의 채널 정보 수신 방법은 먼저, 1 단계에서 사용자가 원하는 채널 정보를 수신하기 위하여 상기 셋톱 박스의 메뉴를 호출하여 위성 탐색에 관련된 메뉴를 선택한다.(S1 참조)In the method for receiving channel information of a set top box according to the related art, first, a menu of the set top box is called to select a menu related to satellite search in order to receive channel information desired by a user in step 1 (see S1).

2 단계는 상기 1 단계에서 선택한 메뉴를 이용하여 상기 사용자가 원하는 채널 정보를 송신하는 위성을 탐색한다.(S2 참조)Step 2 searches for a satellite transmitting the channel information desired by the user using the menu selected in step 1 (see S2).

3 단계는 상기 2 단계에서 탐색된 위성으로부터 그에 해당하는 채널 정보가 수신되어 상기 셋톱 박스의 플래시 메모리에 저장된다.(S3 참조)In step 3, corresponding channel information is received from the satellite searched in step 2 and stored in the flash memory of the set-top box (see S3).

4 단계는 상기 사용자가 수신하기를 원하는 채널 정보가 송신되는 위성이 복수개인 경우 상기 사용자는 상기 2 단계 내지 상기 3 단계를 상기 복수개의 위성수만큼 반복 수행한다(S4 참조)In step 4, when there are a plurality of satellites through which channel information desired by the user is transmitted, the user repeats steps 2 through 3 by the number of satellites (see S4).

그러나, 상기와 같은 종래의 기술에 따른 채널 정보 수신 방법은 복수개의 위성으로부터 채널 정보를 수신할 경우 사용자가 각 위성을 탐색후 그에 따른 채널 정보를 수신하는 과정을 반복 수행하여야 하기 때문에 채널 정보를 수신하는데 소모되는 시간이 증가하는 문제점이 있다.However, in the conventional method of receiving channel information according to the related art, when receiving channel information from a plurality of satellites, channel information is received because the user has to repeat the process of receiving channel information after searching for each satellite. There is a problem that the time consumed to increase.

또한, 사용자의 부주의로 인해 복수개의 위성으로부터 모든 채널 정보를 수신하기전 메뉴의 삭제 관련 기능을 선택하면 플래시 메모리에 기저장된 채널 정보가 삭제되어 버리기 때문에 복수개의 위성으로부터 채널 정보를 수신하는 과정을 다시 수행해야 하는 문제점이 있다.In addition, if the deletion related function of the menu is selected before receiving all the channel information from the plurality of satellites due to user's carelessness, the channel information previously stored in the flash memory is deleted. There is a problem that needs to be done.

본 발명은 상기한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 그 목적은 셋톱 박스에서 복수개의 위성으로부터 채널 정보를 수신하고자할 때 각 위성을 탐색하고 그에 따른 채널 정보를 수신하는 과정을 복수개의 위성 수만큼 연속적으로 반복 수행하게 하는데 있다.The present invention has been made to solve the above-described problems of the prior art, the object of which is to search for each satellite when receiving channel information from a plurality of satellites in a set-top box a plurality of processes for receiving the channel information accordingly It can be repeated as many times as the number of satellites.

도2 는 본 발명에 의한 채널 정보 수신 방법이 도시된 순서도이다.2 is a flowchart illustrating a method of receiving channel information according to the present invention.

상기한 과제를 해결하기 위한 본 발명에 의한 셋톱 박스의 채널 정보 수신 방법의 특징에 따르면, 사용자가 수신하기를 원하는 채널 정보가 송신되는 복수개의 위성에 대한 정보를 상기 사용자가 순서를 부여하여 셋톱 박스에 저장하는 위성정보 저장 단계와, 상기 위성 정보 저장 단계에서 저장된 상기 복수개의 위성을 상기 순서에 따라 순차적으로 탐색하여 그에 따른 채널 정보를 수신하는 것을 상기 복수개의 위성수만큼 반복하는 채널 정보 수신 단계와, 상기 채널 정보 수신 단계에서 상기 순서에 따라 수신되는 상기 채널 정보가 상기 셋톱 박스의 플래시 메모리에 순차적으로 저장되는 채널 정보 저장 단계로 이루어진다.According to a feature of the method for receiving channel information of a set-top box according to the present invention for solving the above problems, the user sets the order of the information on a plurality of satellites to which the channel information that the user wants to receive the set-top box And a channel information receiving step of sequentially searching the plurality of satellites stored in the satellite information storing step according to the order and receiving the channel information according to the order of the plurality of satellites. And storing the channel information sequentially received in the order in the channel information receiving step in the flash memory of the set top box.

이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도2 는 본 발명에 의한 셋톱 박스의 채널 정보 수신 방법이 도시된 순서도이다.2 is a flowchart illustrating a method of receiving channel information of a set-top box according to the present invention.

본 발명에 의한 셋톱 박스의 채널 정보 수신 방법은 먼저, 1 단계에서 사용자가 수신하고자 하는 채널 정보를 송신하는 복수개의 위성 정보에 상기 사용자가 순서를 부여하여 상기 셋톱 박스에 저장한다.(S11 참조)In the method for receiving channel information of a set-top box according to the present invention, first, the user assigns a sequence to a plurality of satellite information for transmitting channel information that the user wants to receive in step 1 and stores it in the set-top box (see S11).

이때, 상기 순서는 사용자의 선택에 의해 변화할 수 있다.In this case, the order may be changed by the user's selection.

2 단계는 상기 1 단계에서 부여된 순서에 따라 순차적으로 상기 복수개의 위성을 탐색한다.(S12 참조)Step 2 searches for the plurality of satellites sequentially in the order given in step 1 (see S12).

3 단계는 상기 2 단계에서 탐색된 위성으로부터 송신되는 채널 정보가 수신되어 상기 셋톱 박스의 플래시 메모리에 저장된다.(S13 참조)In step 3, channel information transmitted from the satellite searched in step 2 is received and stored in the flash memory of the set-top box (see S13).

4 단계는 상기 1 단계에서 상기 셋톱 박스에 저장된 위성 정보수만큼 상기 2 단계 내지 상기 3 단계를 반복 수행한다.(S14 참조)In step 4, steps 2 to 3 are repeated as many times as the number of satellite information stored in the set-top box in step 1 (see S14).

이때, 상기 복수개의 위성을 탐색하여 그에 다른 채널 정보를 수신하는 과정이 셋톱 박스에서 자동으로 이루어지기 때문에 사용자가 각 위성을 탐색후 그에 해당하는 채널 정보를 수신할 필요가 없기 때문에 가정에 셋톱 박스 초기 설치시 그 시간이 감소된다.In this case, since the process of searching for the plurality of satellites and receiving different channel information is automatically performed in the set-top box, the user does not need to receive the corresponding channel information after searching for each satellite. Its time is reduced during installation.

상기와 같이 구성되는 본 발명의 셋톱 박스의 채널 정보 수신 방법은 셋톱 박스에 저장된 복수개의 위성을 부여된 순서에 따라 탐색하고 그에 따른 채널 정보를 수신하는 과정을 복수개의 위성 수만큼 반복 수행함으로써, 채널 정보를 수신하기 위해 소모하는 시간이 감소되고, 이로 인해 사용자가의 편의가 향상되는 효과가 있다.In the method for receiving channel information of the set-top box of the present invention configured as described above, the process of searching for a plurality of satellites stored in the set-top box in a given order and receiving channel information according to the plurality of satellites is repeated. The time consumed to receive the information is reduced, thereby improving the convenience of the user.
