티브이의 부가정보데이터 저장방법{Methode for saving Electronic Program Guide data of TV}Method for saving additional information data of TV {Methode for saving Electronic Program Guide data of TV}

본 발명은 디지털 티브에(Digital TV)에관한 것으로, 특히 다수의 비디오 소스에서 입력되는 각각의 전자프로그램 가이드(이하 EPG)를 통합하여 저장하는 장치에 관한 것이다.The present invention relates to digital TV, and more particularly, to an apparatus for integrating and storing respective electronic program guides (EPGs) input from a plurality of video sources.

디지털 TV 시험 방송을 시작함에 따라 다수의 비디오 소스 ( ATSC, NTSC, DBS,As we start trials of digital TV, a number of video sources (ATSC, NTSC, DBS,

Cable 등 )를 입력으로 하는 TV에서는 이런 다양한 비디오 소스의 EPG 데이터를 종합하여 시청자에게 통합된 EPG 화면을 보여 주는 것이 요구되고 있다.In the case of TVs using a cable, etc., it is required to display the integrated EPG screen to viewers by synthesizing the EPG data of these various video sources.

종래에는 이러한 EPG 데이터 베이스를 구축하기 위해서 별도의 튜너( Tuner )를 부착하여 EPG 전용으로 사용하고, TV를 시청하지 않는 특정 시간대에 TV 시스템의일부가 동작하여 EPG 데이터 베이스를 구축하고 있다. 그러나, 이러한 종래의 방법은 별도의 튜너가 추가로 필요한 단점이 있어, 입력되는 비디오 소스가 증가함에 따라 그 부담도 커지게 된다. 또한, TV의 주전원이 꺼진 상태에서 방송을 수신하는 경우에는 여러가지 하드웨어 규격 대응에도 어려운 점이 있게 된다.Conventionally, in order to build such an EPG database, a separate tuner is attached and used exclusively for EPG, and a part of the TV system operates at a specific time period without watching TV to build an EPG database. However, this conventional method has a disadvantage in that a separate tuner is additionally required, and as the input video source increases, the burden increases. In addition, when receiving a broadcast while the main power supply of the TV is turned off, there are difficulties in supporting various hardware standards.

위성 방송의 경우 DirecTV에서는 지상파 방송 EPG까지 함께 지원하는 APG(Advanced Program Guide)를 계획하고 있으나, 이러한 서비스는 위성 방송 수신자에게만 국한되게된다. 또한, 미국의 디지털 방송규격 단체인 인 ATSC인 경우에는 PSIP(Program system information Protocol;이하 PSIP라 명 함)정보로부터 EPG 데이터를 뽑아 내야하는데, 각 방송국이 자기 채널에 대한 PSIP 정보만을 송출할 경우, TV 수신기는 해당 채널에 대한 EPG 데이터 외에는 다른 방송국 채널에 대한 EPG 데이터를 얻을 수가 없다.In the case of satellite broadcasting, DirecTV plans an Advanced Program Guide (APG) to support terrestrial broadcasting EPG, but such services are limited to satellite broadcasting receivers. In addition, in the case of ATSC, a digital broadcasting standard organization in the United States, EPG data must be extracted from PSIP (Program System Information Protocol) information. When each broadcasting station transmits only PSIP information about its own channel, The TV receiver cannot obtain EPG data for other broadcaster channels other than the EPG data for the corresponding channel.

본발명은 상기의 문제점을 해결하기 위한것으로 별도의 EPG데이타 수신용 튜너없이 다양한 소스에서 입력되는 EPG데이타를 수신할 수 있는 디지털 티브이를 제공하는 데 있다.The present invention to solve the above problems is to provide a digital TV that can receive EPG data input from various sources without a separate tuner for receiving EPG data.

본 발명의 제 1 특징은 TV 시청 시간의 대부분이 오직 하나의 비디오 소스만을 처리하는 데 비해, 각 비디오 소스 마다 각자의 고주파 수신 회로( 튜너, TP 등 )를 가지고 있는 점을 토대로 현재 시청하고 있지 않는 비디오 소스를 통해 입력되는 EPG 데이터를 추출하는 EPG 데이터 추출 수단을 갖는다.The first feature of the present invention is that it is not currently being viewed based on the fact that most of the TV viewing time only handles one video source, but each video source has its own high frequency reception circuit (tuner, TP, etc.). EPG data extraction means for extracting EPG data input through a video source.

본 발명의 제 2 특징은 상기 제 1 특징에서 EPG 데이터를 추출할 때, 현재 동작 가능한 비디오 소스를 판별하고,동작 가능한 비디오 소스 중 현재 시청하고 있지 않는 비디오 소스를 판별한 후, 각 비디오 소스, 각 채널에 대해 우선 순위를 가지고 데이터를 추출하는 수단을 갖는다. 좀더 설명하자면 비디오 소스는 ATSC, NTSC, DBS, Cable 순, 채널은 선호 채널 먼저, 나머지 채널은 나중에 추출한다.The second aspect of the present invention is that when extracting the EPG data from the first aspect, it is possible to determine a video source that is currently operable and to determine which video source is not currently being watched from among the video sources, each video source, each It has a means to extract data with priority for the channel. More specifically, the video source is ATSC, NTSC, DBS, Cable, and the channel is the preferred channel first, and the rest of the channels are extracted later.

본 발명의 제 3 특징은 상기 제 2 특징에 의해 추출된 EPG 데이터를 통일된 EPG 데이터 형태로 변환하여 통합 EPG 데이터 베이스를 구축하는 수단을 갖는다.A third aspect of the present invention has a means for converting the EPG data extracted by the second aspect into a unified EPG data form to build an integrated EPG database.

이하 본 발명을 제1도에서 4도를 이용하여 상세히 설명한다.제1도는 본발명의 기본 구성도로서, 먼저 디지털 방송 수신용튜너,위성용튜너,아나로그 방송수신용튜너로 부터 방송데이타가 입력된다.즉 비디오 소스별로 각자의 고주파 수신 회로인 튜너등을 독립적으로 가지고 있어서,시청자가 리모콘을 조작하여 채널을 선택함에 따라 해당 비디오 소스 입력부가 동작되고, ROM에 저장된 프로그램에 따라 중앙 처리 장치부의 콘트롤 신호( control )에 의해 각 비디오 소스 입력부로부터 영상 신호, 음성 신호 및 부가 정보( EPG 데이터 등 )를 선택적으로 읽어 들여 미리 정의된 통일된 형식으로 변환하여 RAM에 저장할 수 있도록 구성되어 있다.Hereinafter, the present invention will be described in detail with reference to FIGS. 1 to 4. FIG. 1 is a basic configuration diagram of the present invention. First, broadcast data is input from a digital broadcast reception tuner, a satellite tuner, and an analog broadcast reception tuner. In other words, each video source has its own high-frequency receiver circuit tuner, etc., so that the viewer operates the remote control to select a channel, and the corresponding video source input unit is operated, and the central processing unit controls according to the program stored in the ROM. It is configured to selectively read a video signal, an audio signal and additional information (such as EPG data) from each video source input unit by a signal and convert it into a predefined uniform format and store it in a RAM.

제 2 도는 본 발명의 흐름도로서 선택된 채널의 소스아이디를 마이컴에서 인지를 하고 현재 시청중인 소스가 사용중인지를 판별한다음 시청하고 있지않은 소스이면 시청하고 있지않은 소스중 정해진 순서에따라 먼저 튜닝을 한 후 수신되는 데이타 중에서 부가 정보를 추출하여 현재 시청 중인 채널의 EPG데이타를 읽어들인다. 이렇게 읽은 EPG데이타를 설게자가 저의한 통합 EPG데이타 베이스에적합한 형식으로 변환 한 다음 통합 EPG데이타 베이스에 저장을 하고 종료를 하게 된다.2 is a flowchart of the present invention, the microcomputer recognizes the source ID of the selected channel and determines whether the source currently being viewed is in use. After that, the additional information is extracted from the received data and the EPG data of the channel currently being viewed is read. The EPG data read in this way is converted into a format suitable for the integrated EPG database suggested by the author, and then saved in the integrated EPG database and finished.

제 4도는 선호 채널과 관련된 부분으로서 상기의 제3도와 기본적인 개념은 동일하다. 먼저 현재 시청하고 있는 채널인지를 판별하고 시청중이 아니면 이와 관련된 하드웨어를 가동 시킨다. 그 다음에 사용자가 설정한 선호채널의 순서에 따라 차레로 튜닝하고 선택된 채널로 부터 EPG데이터를 읽어 들인다.이렇게 읽혀진 EPG데이터는 통합EPG데이터에 적합한 형식으로 변환되어 데이타 베이스에 저장된다. 그리고 마지막 선호채널인지를 판단하고 마지막일 경우에는 나머지 채널을 튜닝한 다음 해당 채널의 EPG데이타를 읽어 들인다.마찬가지로 적합한 형식으로 EPG데이터를 변환 한 다음 데이터 베이스에 저장하고 종료한다.4 is a part related to the preference channel, and the basic concept of FIG. 3 is the same. First, determine whether the channel is currently being watched, and if not, start the hardware related to it. Next, the user tunes in order according to the preference channel set by the user and reads EPG data from the selected channel. The EPG data is converted into a format suitable for the integrated EPG data and stored in the database. It determines whether it is the last favorite channel, and if it is the last time, it tunes the remaining channels and reads EPG data of the corresponding channel. Similarly, the EPG data is converted into a suitable format, and then stored in the database and finished.

제4도는 통합 EPG데이터 베이스의 구성예로서 4-1)도는 현재 시청중인 채널을 통하여 미리 읽어들인 아나로그용 EPG데이터를 나타낸다. 4-2)도는 아나로그방송을 시청하는 동안 타 방송, 즉 디지털 방송과 관련된 EPG데이터를 수신한 디지털용 EPG데이터를 나타낸다.제4-3)도는 아나로그 방송을 시청하는 동안 위성방송EPG데이터를 수신하는 구성예를 나타낸 것이다. 4-4)도는 통합된 EPG데이타베이스 구성예를 보여준다. 여기서 제 4도를 부연하여 설명하자면 먼저 시청중인 방송과 관련된 EPG데이타를 추출하고 그다음에 기 결정된 순서에 의해 차례로 타방송과 관련된 EPG데이터를 수신한 다음 이를 통합하여 하나의 데이타 베이스에 관리하도록 저장하는 것이다.4 is an example of the configuration of the integrated EPG database. FIG. 4-1) shows analog EPG data read in advance through the channel currently being viewed. 4-2) shows digital EPG data which received other broadcasting, that is, EPG data related to digital broadcasting while watching analog broadcasting. FIG. 4-3) shows satellite broadcasting EPG data while watching analog broadcasting. The example of a structure to receive is shown. 4-4) shows an example of integrated EPG database configuration. Here, in detail with reference to FIG. 4, the EPG data related to the broadcast being watched are first extracted, and then EPG data related to other broadcasts are received in order according to a predetermined order, and then integrated and stored to be managed in one database. will be.

이상에서 살펴본 바와 같이 본 발명은 첫째, 각 비디오 소스마다 추가로 별도의 EPG용 튜너를 부착하지 않고도 타 소스에 존재하는 튜너를 통하여 각 비디오 소스로부터 EPG 데이터를 수신할 수 있으며,둘째, TV의 주 전원이 꺼진 상태에서는 방송 수신을 하지 않으므로, 여러 가지 하드웨어 규격에 대응이 용이하고, 세째, 다수의 비디오 소스로부터 읽어 들인 EPG 데이터를 통일된 하나의 데이터 베이스로 구축하여 관리하므로, 시청자가 모든 비디오 소스에 관해 통합된 프로그램 안내를 받을 수 있는 효과가 있다.As described above, in the present invention, first, each EPG data can be received from each video source through a tuner existing in another source without attaching a separate EPG tuner for each video source. Since the broadcast reception is not performed when the power is turned off, it is easy to cope with various hardware standards. Third, the EPG data read from a plurality of video sources is constructed and managed as a unified database so that the viewer can view all the video sources. It is effective to receive integrated program guidance on.
