디지털 케이블 방송시스템의 방송프로그램정보 안내방법{The guiding method of broadcasting program information for digital CATV system}The guiding method of broadcasting program information for digital CATV system

본 발명은 디지털 케이블 방송시스템에 관한 것으로서, 더욱 상세하게는 방송신호 외에도 부가정보인 방송프로그램 정보를 송신할 수 있는 디지털 케이블 방송시스템에서 사용자에게 방송프로그램정보를 안내하는 방법에 관한 것이다.The present invention relates to a digital cable broadcasting system, and more particularly, to a method of guiding broadcast program information to a user in a digital cable broadcasting system capable of transmitting broadcast program information as additional information in addition to a broadcast signal.

동축케이블이나 광케이블과 같은 광대역 신호를 전송할 수 있는 전송매체를 통해 영상과 음성정보를 가입자에게 전송하기 위해 도래된 CATV(Community Antenna Television)는 초기 난시청 해소를 목적으로 공용안테나를 설치하여 텔레비전방송을 가입자에게 단순히 전송하는 방식으로 시작하였으나. 현재에는 단순한 분배서비스를 넘어서 가입자에게 자주방송, 홈쇼핑 등과 같은 쌍방향기능을 첨가하여 미래 정보화사회를 앞당기는 중요한 미디어로 떠오르고 있으며, 최근에는 공중파 전파에 의한 텔레비전 방송에 대응하여 케이블을 이용한 텔레비전이라는 의미로써 CABLE TELEVISION의 약자로써 사용되고 있다.CATV (Community Antenna Television), which was introduced to transmit video and audio information to subscribers through a transmission medium capable of transmitting broadband signals such as coaxial cable and optical cable, has installed a common antenna for the purpose of eliminating astigmatism. I started by simply sending to. Nowadays, it is emerging as an important media to advance the information society by adding interactive functions such as independent broadcasting, home shopping, etc. to subscribers beyond the simple distribution service. It is used as an abbreviation for CABLE TELEVISION.

또한, 아날로그방식의 케이블 방송시스템에 비해 다양한 서비스를 제공할 수 있는 디지털방식의 케이블 방송시스템에서, 가입자들은 아날로그신호로 처리되는 일반 텔레비전수신기 외에도 디지털로 전송된 영상/음성데이터를 복호화하여 일반 텔레비전수상기에서 인식할 수 있는 신호로 변환하는 역할을 하는 셋탑박스를 구비해야 한다. 이 셋탑박스의 주요기능은 MPEG 등으로 압축된 신호를 복호(Decoding), 복조(Demodulation), 신장(Decompression)하는 것이나, 이는 전송매체별 전송방식에 따라 다소 차이가 있다,In addition, in a digital cable broadcasting system capable of providing various services compared to an analog cable broadcasting system, subscribers decode video / audio data transmitted digitally in addition to a general television receiver processed as an analog signal. It should have a set-top box that converts the signal into a signal that can be recognized. The main function of this set-top box is to decode, demodulate, and decompress the signal compressed with MPEG, but this is somewhat different depending on the transmission method for each transmission medium.

본 발명은 디지털 케이블 방송시스템에서, 사용자가 최근의 방송프로그램에 대한 안내를 간편하게 받을 수 있도록 한 디지털 케이블 방송시스템의 방송프로그램정보 안내방법을 제공하는 것을 그 목적으로 한다.An object of the present invention is to provide a broadcast program information guide method of a digital cable broadcast system in which a user can easily receive a guide for a recent broadcast program in a digital cable broadcast system.

도 1은 본 발명에 적용될 디지털 케이블 방송시스템의 개략도로서, 참조부호 10은 케이블 방송센터이고, 참조부호 12a∼12n은 가입자측 장치이고, 참조부호 14는 케이블 방송센터(10)와 가입자측 장치(12a∼12n)를 각각 연결하기 위한 전송로이다.1 is a schematic diagram of a digital cable broadcasting system to be applied to the present invention, wherein reference numeral 10 denotes a cable broadcasting center, reference numerals 12a to 12n denote subscriber equipment, and reference numeral 14 denotes a cable broadcasting center 10 and a subscriber subscriber apparatus ( It is a transmission path for connecting 12a-12n), respectively.

케이블 방송센터(10)에서는 원(source) 방송국으로부터 수신된 텔레비전 방송신호를 중계하는 것 이외에도 자국 방송을 가입자에게 전송할 수 있다. 케이블 방송센터(10)로부터 가입자측 장치(12a∼12n)로 전송되는 데이터는 디지털 데이터로서, 영상신호와 음성신호 이외에도 방송프로그램정보와 같은 부가정보를 포함한 패킷단위로 전송된다. 가입자측 장치(12a∼12n)는 일반 텔레비전 수상기(122a∼122n)와 케이블 방송센터(10)로부터 수신된 방송신호를 가공하여 텔레비전 수신기에서 인식할 수 있는 아날로그 신호로 변환시켜주는 셋탑박스(120a∼120n)로 이루어진다. 전송로(14)는 동축케이블이나 광케이블과 같은 전송매체를 이용한다.In addition to relaying the television broadcast signal received from the source broadcast station, the cable broadcast center 10 may transmit its own broadcast to the subscriber. The data transmitted from the cable broadcasting center 10 to the subscriber-side devices 12a to 12n are digital data, and are transmitted in packet units including additional information such as broadcast program information in addition to video signals and audio signals. Subscriber-side devices 12a through 12n process set-top boxes 120a through 12b which convert broadcast signals received from general television receivers 122a through 122n and cable broadcasting center 10 into analog signals that can be recognized by a television receiver. 120n). The transmission path 14 uses a transmission medium such as a coaxial cable or an optical cable.

도 2는 도 1에 도시된 셋탑박스들(120a∼120n)의 상세 구성 블록도로서, 데이터 수신부(20), MPEG(Motion Pictures Experts Group) 복조부(22), CPU(24), 방송프로그램정보 저장부(26), 응용프로그램부(28) 및 명령 인가부(30)로 이루어진다.FIG. 2 is a detailed block diagram of the set-top boxes 120a to 120n shown in FIG. 1, which includes a data receiver 20, a Motion Pictures Experts Group (MPEG) demodulator 22, a CPU 24, and broadcast program information. It consists of a storage unit 26, an application program unit 28 and a command application unit 30.

데이터 수신부(20)는 케이블 방송센터(10)로부터 송신된 MPEG 데이터를 수신하는 수단이고, MPEG 복조부(22)는 데이터 수신부(20)에서 수신한 MPEG 데이터 중 영상/음성데이터는 복조하여 영상/음성처리부(미도시됨)로 전송하고, MPEG 데이터 중 부가정보인 방송 프로그램정보는 복조하여 CPU(24)로 전송하는 수단이다. 방송프로그램정보 저장부(26)는 CPU(24)에서 수신한 방송프로그램 정보에 대해 응용프로그램부(28)에서 가공 처리한 방송프로그램 정보를 최종적으로 저장하기 위한 수단이다. 방송프로그램정보는 방송국과의 협약에 따라 달라질 수 있지만, 본 발명에서는 방송시간, 프로그램 길이, 프로그램 제목, 방송채널, 프로그램종류, 등급 및 방송프로그램을 전송한 시간정보 등을 포함하는 것을 전제로 한다.The data receiver 20 is a means for receiving the MPEG data transmitted from the cable broadcasting center 10, and the MPEG demodulator 22 demodulates the video / audio data among the MPEG data received from the data receiver 20 to output the video / audio. It transmits to a voice processing unit (not shown), and broadcast program information which is additional information in MPEG data is demodulated and transmitted to CPU24. The program information storage unit 26 is a means for finally storing the program information processed by the application program unit 28 with respect to the program information received from the CPU 24. The broadcast program information may vary depending on the agreement with the broadcasting station. However, the present invention is based on the premise that the broadcast program information includes a broadcast time, a program length, a program title, a broadcast channel, a program type, a rating, and time information of a broadcast program.

도 3은 본 발명에 따른 방송프로그램정보 안내방법을 설명하기 위한 흐름도로서, 도 3을 참조하여 도 1에 도시된 장치의 동작을 설명하면 다음과 같다.3 is a flowchart illustrating a method for guiding broadcast program information according to the present invention. Referring to FIG. 3, the operation of the apparatus shown in FIG. 1 will be described below.

전송로(14)를 통해 전송된 방송데이터를 수신한다(S300).The broadcast data transmitted through the transmission path 14 is received (S300).

수신된 방송데이터가 방송프로그램정보인가를 판단한다(S302). 즉, 방송신호는 영상데이터, 음성데이터 및 부가데이터가 각각 패킷단위로 전송되는데, 이 때 전송되는 각각의 데이터는 그 정보가 어떤 종류의 데이터인가를 판별할 수 있도록 ID정보가 수록된다. 따라서, 이 ID정보를 이용하여 전송된 방송데이터가 영상데이터인지, 음성데이터인지, 또는 방송프로그램정보를 나타내는 데이터인지를 판단할 수 있다.It is determined whether the received broadcast data is broadcast program information (S302). That is, in the broadcast signal, video data, audio data, and additional data are transmitted in packet units, and each piece of data transmitted includes ID information so as to determine what kind of data the information is. Therefore, it is possible to determine whether the transmitted broadcast data is video data, audio data, or data representing broadcast program information using this ID information.

S302의 판단결과, 수신된 데이터가 방송프로그램정보가 아니면, 영상/음성처리를 수행하지만(S304), 방송프로그램정보이면 갱신된 데이터인가를 판단한다(S306). 즉, 방송프로그램정보에는 이 방송프로그램정보를 송신한 시간정보가 수록되어 전송되기 때문에 기 저장된 방송프로그램정보가 가공된 시간과, 현재 수신된 방송프로그램정보의 전송시간을 비교하여, 기 저장된 방송프로그램이 가공된 이후에 전송된 방송프로그램정보인가를 확인해야한다. 만약, S306의 판단결과, 현재 가공되기 전의 방송프로그램정보이면, 이 방송프로그램정보는 가치가 없는 것이므로 버린다(S308). 그러나, 가공된 이후의 방송프로그램정보이면, 이 방송프로그램정보를 화면상에 표시 가능하도록 가공하여 저장한다(S310). 즉 가공/저장한다는 것은 수신된 각각의 데이터 즉, 방송시간, 프로그램길이, 프로그램제목, 방송채널, 프로그램종류, 등급 등을 그 종류별로 분류하여 사용자가 검색하기 편리한 데이터로 처리하는 것을 의미한다. 따라서, 사용자는 방송시간순서, 프로그램 종류, 제목별로 분류된 정보를 볼 수 있다.As a result of the determination in S302, if the received data is not broadcast program information, video / audio processing is performed (S304), but if it is broadcast program information, it is determined whether or not it is updated data (S306). That is, since the broadcast program information includes time information for transmitting the broadcast program information and is transmitted, the stored broadcast program is compared with the time when the previously stored broadcast program information is processed and the transmission time of the currently received broadcast program information. After processing, it is necessary to confirm whether the program information is transmitted. If, as a result of the determination in S306, the broadcast program information before being processed, the broadcast program information is discarded because it is not valuable (S308). However, if the processed program information is processed, the program information is processed and stored to be displayed on the screen (S310). In other words, processing / storing means to classify each received data, that is, broadcasting time, program length, program title, broadcasting channel, program type, and grade, into types that are convenient for the user to search. Accordingly, the user can view information classified by broadcasting time sequence, program type, and title.

그 다음, 사용자로부터 명령 인가부(30)를 통해 방송프로그램정보의 표시요청이 있는지를 판단하여(S312), 요청이 있으면 방송프로그램정보를 표시하고(S314), 그렇지 않고 일정시간이 경과하면 S300으로 리턴되어 상술한 과정을 반복 수행한다.Then, it is determined from the user whether or not there is a request for displaying the program information through the command applier 30 (S312), and if there is a request, the program information is displayed (S314). It returns and repeats the above process.

상술한 바와 같이 본 발명에 따른 디지털 케이블 방송시스템의 방송프로그램정보 안내방법에 의하면, 신문이나 별도의 프로그램정보 제공수단을 이용하지 않고 간단하고 손쉽게 방송프로그램정보를 얻을 수 있는 효과가 있다.As described above, according to the program information guide method of the digital cable broadcasting system according to the present invention, there is an effect that the program information can be obtained simply and easily without using a newspaper or a separate program information providing means.
