본 발명은 채널 선호도에 따른 프로그램 가이드 표시 방법에 관한 것으로, 특히 텍스트 정보를 기초로 하여 사용자가 선호하는 장르 및 선호 채널을 학습하여 우선 순위별로 정보를 제공할 수 있도록 한 채널 선호도에 따른 프로그램 가이드 표시 방법에 관한 것이다. The present invention relates to a method of displaying a program guide according to channel preference, and in particular, to display a program guide according to channel preference so as to provide information by priority by learning a user's preferred genre and preferred channel based on text information. It is about a method.

현재, 오픈 케이블은 미국내 각 케이블 MSO마다 다른 디지탈 셋톱 박스의 규격을 통일하기 위하여 만들어지고 있는 디지탈 케이블 방송 및 셋톱 박스에 관한 새로운 규격으로 현재 진행중이다.Currently, Open Cable is currently in progress as a new standard for digital cable broadcasting and set-top boxes that is being developed to unify the specifications of different digital set-top boxes for each cable MSO in the United States.

상기 오픈케이블 셋톱 박스에서 채널 및 프로그램에 관한 정보는 SI이라 명명된 SCTE DVS234 규격을 사용할 예정이며 각 채널에 대한 프로그램 가이드는 EIT 및 ETT 텍스트 테이블을 통해 제공되어지고, 또한 셋톱 박스는 상기 프로그램 가이드에 대한 정보를 다운 로드 받아 사용자에게 프로그램에 관한 가이드를 여러 형태로 제공할 수 있다.Information on channels and programs in the open cable set-top box will use the SCTE DVS234 standard named SI, and program guides for each channel are provided through the EIT and ETT text tables. You can download information about this program and provide the user with a guide to the program in various forms.

그러나, 상기와 같은 종래 기술은 사용자에게 프로그램에 관한 가이드시 사용자의 선호하는 장르 및 채널에 대한 정보를 근거로 하여 제공하지 못하므로 사용자의 채널 선택시 번거로운 절차를 거쳐야 하는 문제점이 있었다.However, the prior art as described above does not provide a user with a guide about a program based on information on a user's preferred genre and channel.

따라서, 상기와 같은 문제점을 감안하여 창안한 본 발명은 사용자의 기호에 맞게 장르및 채널별 우선순위로 프로그램을 가이드하여 채널 선택시 빠르고 쉽게 원하는 채널을 시청할 수 있도록 한 채널 선호도에 따른 프로그램 가이드 표시방법을 제공함에 그 목적이 있다. Accordingly, the present invention, which was devised in view of the above-mentioned problems, guides the program according to the genre and the priority of each channel according to the user's preference so that the user can watch the desired channel quickly and easily when selecting a channel. The purpose is to provide.

상기와 같은 목적을 달성하기 위한 본 발명은 모든 채널의 EIT 및 ETT 정보를 분석하여 장르를 분류하는 제1 단계와; 사용자가 채널을 선택하여 바꾸면 이전 채널의 장르 분석 및 시청시간을 계산하여 장르의 선호순위를 계산하는 제2 단계와; 상기 제2 단계의 이전 채널 시청시간을 이용하여 채널의 우선순위를 계산하는 제3 단계와; 사용자가 선호순위 매뉴얼 셋팅을 원하여 사용자의 입력에 따른 매뉴얼 우선순위를 설정하는 제4 단계로 수행함을 특징으로 한다.The present invention for achieving the above object comprises a first step of classifying the genre by analyzing the EIT and ETT information of all channels; A second step of calculating a preference of genres by calculating genre analysis and viewing time of a previous channel when a user selects and changes a channel; Calculating a priority of the channel using the previous channel viewing time of the second step; In the fourth step of setting the manual priority according to the user's input, the user desires manual setting.

이하, 본 발명에 의한 채널 선호도에 따른 프로그램 가이드 표시방법에 대한 실시예의 작용 및 효과를 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the operation and effects of the embodiment of the program guide display method according to the channel preference according to the present invention will be described in detail.

도1은 본 발명 채널 선호도에 따른 프로그램 가이드 표시 방법에 대한 동작 흐름도로서, 이에 도시한 바와같이 모든 채널의 EIT 및 ETT 정보를 분석하여 장르를 분류하는 제1 단계와; 사용자가 채널을 선택하여 바꾸면 이전 채널의 장르분석 및 시청시간을 계산하여 장르의 선호순위를 계산하는 제2 단계와; 상기 제2 단계의 이전 채널 시청시간을 이용하여 채널의 우선순위를 계산하는 제3 단계와; 사용자가 선호순위 매뉴얼 셋팅을 원하여 사용자의 입력에 따른 매뉴얼 우선순위를 설정하는 제4 단계로 이루어지며, 이와같은 본 발명의 동작을 설명한다.1 is a flowchart illustrating a method for displaying a program guide according to a channel preference according to the present invention, and as shown therein, a first step of classifying genres by analyzing EIT and ETT information of all channels; A second step of calculating a preference of genres by calculating genre analysis and viewing time of a previous channel when a user selects and changes a channel; Calculating a priority of the channel using the previous channel viewing time of the second step; The fourth step is to set the manual priority according to the user's input in order for the user to set the preference manual. The operation of the present invention will be described.

먼저, 모든 채널에 대한 EIT 및 ETT 테이블이 분석되면 모든 채널을 4~6개의 장르로 분류하고, 그 다음 사용자가 채널을 교체할 때마다 교체 이전의 채널에 대한 장르 분석 및 시청 시간을 계산하여 매번 장르 선호도값 및 채널 선호도값을 다시 산출한후, 이 산출값을 기준으로 우선순위를 매김하여 사용자가 메뉴 디스플레이시 도2 내지 도5와 같이 메뉴화면을 보여준다.First, if the EIT and ETT tables for all channels are analyzed, classify all channels into 4-6 genres, then calculate the genre analysis and watch time for the channels before the replacement each time the user changes channels. After calculating the genre preference value and the channel preference value again, the priority is given based on the calculated value, and the menu screen is displayed as shown in FIGS. 2 to 5 when the user displays the menu.

도2는 초기 메뉴화면을 보인 예시도로서, 채널가이드는 초기 메뉴가 모든 채널에 대한 정보를 제공하고, 서치(Search)는 채널에 대한 탐색 기능을 제공하며, 유저 페이버리트(User Favorite)는 사용자가 선호하는 장르가 우선 순위별로 사용자의 기호에 맞게 프로그램 을 제공한다.FIG. 2 is an exemplary view showing an initial menu screen, where a channel guide provides information on all channels, a search provides a search function for a channel, and a user favorite is a user. Preferred genre offers programs to suit user preferences by priority.

여기서, 상기 유저 페이버리트(User Favorite) 버턴을 누르면 도3과 같은 메뉴화면이 디스플레이되어 사용자의 선호장르가 우선순위별로 표시되는데, 예를들어 스포츠, 영화, 뉴스등의 순서로 채널에 관한 기호가 순위 메김되어 있다.In this case, when the user favorite button is pressed, a menu screen as shown in FIG. 3 is displayed, and the user's preferred genre is displayed in order of priority. For example, a symbol for a channel is displayed in order of sports, movies, and news. It is ranked.

그리고, 상기 도3의 좌측 상단의 메뉴얼 버턴을 누르면 순위를 자동학습 알고리즘에 관계없이 임의대로 셋팅할 수 있다.When the manual button on the upper left of FIG. 3 is pressed, the ranking may be arbitrarily set regardless of the automatic learning algorithm.

만약, 상기 스포츠 버턴을 누르면 도4와 같은 메뉴화면이 디스플레이되는데, 여기서는 스포츠 채널중에서도 선호도 우선 순위별로 채널 번호와 채널명을 표시하여 준다.If the sports button is pressed, a menu screen as shown in FIG. 4 is displayed. Here, among the sports channels, the channel number and the channel name are displayed for each priority priority.

이때, 도5는 상기 도4의 메뉴화면중 선호도 순위가 2등인 SNEAK를 누를때 나타나는 화면이며, 선택버튼인 12번부터 나머지는 순위별로 비교하면서 시간 및 내용에 대한 정보를 볼 수 있다.In this case, FIG. 5 is a screen that appears when the SNEAK having a preference rank of 2, among the menu screens of FIG. 4, is displayed. From the selection 12, the rest of the menus can be viewed by comparing the ranking and time and contents.

여기서, 상기와 같은 메뉴화면을 위해서는 채널의 장르분류, 장르 및 채널 선 호값의 정량화가 필수적이며, 이 정량화된 값을 바탕으로 우선순위를 정한다.Here, for the menu screen as described above, it is essential to quantify the channel genre classification, genre, and channel preference value, and determine the priority based on the quantified value.

보다 상세하게, 도1을 참조하여 본 발명을 설명한다.More specifically, the present invention will be described with reference to FIG.

우선, 셋톱이 파워온되어 EIT 및 ETT 테이블을 분석하는 루틴에서 상기 테이블을 데이터 베이스하면 이 데이터 베이스가 제공하는 정보를 바탕으로 장르 분류를 해 두고, 사용자의 채널 교체를 기다린다.First, when the set-top is powered on and the database is analyzed in the routine for analyzing the EIT and ETT tables, the genre is classified based on the information provided by the database, and the user waits for a channel change.

이때, 사용자가 새로운 채널을 선택하면 이전 채널에 대한 시청시간 및 이전채널이 속한 장르의 값에 채널 선택 초기값(사용자가 메모리의 크기에 따라 설정)을 누적하여 가산하는데, 여기서 상기 시청시간은 가중치(Kt)를 승산하여 합산한다.At this time, when the user selects a new channel, the channel selection initial value (set by the user according to the size of the memory) is accumulated and added to the viewing time for the previous channel and the genre to which the previous channel belongs, where the viewing time is weighted. Multiply and add Kt.

만약, 상기 연산 결과 오버플로우가 생기면 오프셋값을 빼준다.If an overflow occurs as a result of the operation, the offset value is subtracted.

또한, 상기와 같은 연산을 채널에 대해서도 수행하여 그에 따른 선호도값은 이이피롬에 저장되며, 각 장르 및 채널마다 이 값을 저장하는 메모리번지가 하나 할당되어 계속 누적되고, 만약 사용자가 메뉴얼로 셋팅을 원할 경우에는 사용자의 입력에 의해 우선순위를 결정할 수 있다.In addition, the above operation is performed on the channel, and the preference value is stored in YPIROM, and a memory address for storing this value is allocated to each genre and channel and accumulated continuously. If desired, priority can be determined by user input.

이상에서 상세히 설명한 바와 같이 사용자의 채널 선택 내용을 학습하여 기호에 맞게 장르별 채널별 우선 순위로 프로그램 가이드를 제공함으로써 채널선택시 빠르고 쉽게 원하는 프로그램을 시청할 수 있는 효과가 있다.As described in detail above, by learning the channel selection contents of the user, the program guide is provided with the priority of each genre according to the genre according to the taste, so that the user can watch the desired program quickly and easily.
