Abstract

본 발명은 SO에서 자체광고를 삽입할 수 있도록 하는 디지탈 CATV의 광고 삽입장치에 관한 것이다.The present invention relates to a digital CATV advertisement inserting device capable of inserting its own advertisement in an SO.

본 발명은 MSO에서 큐 톤 신호를 검출하여 엔코딩시 일반 비디오 신호와 광고용 비디오 신호를 분리하여 엔코딩함으로써 SO에서 광고용 비디오 신호 부분에 자체 광고를 삽입할 수 있도록 한 것이다.In the present invention, a quartz signal is detected in the MSO, and a general video signal and an advertising video signal are separately encoded and encoded during encoding, thereby allowing the SO to insert its own advertisement into a part of the video signal for advertisement.

Description

디지탈 케이블티브이(CATV)의 광고삽입장치Ad insertion device of digital cable TV (CATV)

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.

제 1 도 (a), (b)는 본 발명에 따른 디지탈 CATV의 광고삽입장치의 구성 블럭도1 (a) and 1 (b) are block diagrams of a configuration of a digital CATV advertisement inserting apparatus according to the present invention

Claims (3)

입력되는 아날로그 비디오 신호중의 수직 블랭킹 신호에 삽입된 큐 톤신호를 검출하여 일반 비디오 신호와 광고용 비디오 신호를 분리하여 엔코딩한 후 다중화하여 SO로 전송하는 송신수단과, 상기 송신수단으로부터 전송되어온 신호를 일반 비디오 신호와 광고용 비디오 신호로 분리하여 광고용 비디오 신호의 기간중에 자체 광고용 비디오 신호를 삽입하여 출력하는 수신수단으로 구성됨을 특징으로 하는 디지탈 CATV의 광고삽입장치.A transmitting means for detecting a quit-tone signal inserted in a vertical blanking signal in an input analog video signal to separate and encode a general video signal and an advertising video signal, multiplexing the multiplexed video signal, and transmitting the multiplexed signal to the SO; And a receiving means for separating the video signal and the advertisement video signal into a video signal for advertisement and a video signal for advertisement during a period of the video signal for advertising. 제 1 항에 있어서, 상기 송신수단은 입력되는 아날로그 비디오 신호에 실려 있는 큐 톤 신호를 검출하는 큐 톤 검출부(11)와, 상기 아날로그 비디오 신호를 일반 비디오 신호와 광고용 비디오 신호로 분리하여 스위칭부(12)와, 상기 큐 톤 검출부(11)의 출력에 따라 상기 스위칭부(12)의 스위칭을 제어하는 스우칭 제어부(13)와, 상기 스위칭부(12)를 통하여 출력되는 일반 비디오 신호를 MPEG2 트랜스포트 스트림으로 엔코딩하며 엔코딩시 지역광과와 MSO광고 구분을 위한 ID를 삽입하는 광고용 엔코터(15)와, 상기 비디오 엔코더(14)와 광고용 엔코더(15)의 출력신호를 ATM 셀화하고 다중화하는 ATM 셀화 및 다중화부(16)와, 각 채널의 ATM 셀화 및 다중화부(16)의 출력을 다중화하여 출력하는 다중화부(17)로 구성됨을 특징으로 하는 디지탈 CATV의 광고삽입장치.2. The apparatus according to claim 1, wherein the transmitting means comprises: a queue tone detecting unit (11) for detecting a queue tone signal carried on an input analog video signal; and a switching unit A switching control unit 13 for controlling switching of the switching unit 12 according to an output of the qubit tone detecting unit 11 and a switching unit 12 for switching a general video signal output through the switching unit 12 to an MPEG2 transform An advertisement encoder 15 which encodes the video signal into a port stream and inserts an ID for distinguishing the local light and the MSO advertisement at the time of encoding and an ATM for multiplexing output signals of the video encoder 14 and the advertising encoder 15, And a multiplexing unit (17) for multiplexing and outputting outputs of the ATM cellization and multiplexing unit (16) of each channel. 제 1 항에 있어서, 상기 수신수단은 상기 송신수단으로부터 전송된 신호를 역다중화하여 각 채널별로 분리한 후, 다시 일반 비디오 신호와 광고용 비디오 신호로 분리하는 역다중화부(21)와, 상기 역다중화부(21)를 통하여 출력되는 MSO 광고용 비디오 신호나 자체 광고용 서버(22)로부터의 지역광고를 출력하는 스우칭부(23)와, 상기 역다중화부(21)를 통하여 출력되는 광고용 비디오 신호로부터 ID를 검출하거나 자체 프로그램에 의하여 상기 스위칭부(23)를 제어하는 스위칭 제어부(24)와, 상기 역다중화(21)를 통하여 출력되는 일반 비디오 신호와 스위칭부(23)를 통하여 출력되는 광고용 비디오 신호를 합성하는 맵퍼(25)와, 각 채널의 맵퍼(25)의 출력신호를 ATM셀화하고 다중화하여 출력하는 ATM 셀화 및 다중화부(26)로 구성됨을 특징으로 하는 디지탈 CATV의 광고삽입장치.2. The apparatus according to claim 1, wherein the receiving means comprises: a demultiplexer (21) for demultiplexing the signals transmitted from the transmitting means and separating the demultiplexed signals into respective channels and then separating the signals into a general video signal and a commercial video signal; A squeegee 23 for outputting an MSO advertisement video signal output through the unit 21 or a local advertisement from the server 22 for the advertisement itself and an ID signal from the advertisement video signal output through the demultiplexer 21 A switching control unit 24 for controlling the switching unit 23 by detecting or synthesizing a general video signal output through the demultiplexing unit 21 and a video signal for advertisement output through the switching unit 23, And an ATM cellization and multiplexing unit 26 for multiplexing the output signals of the mapper 25 of each channel into ATM cells and outputting the multiplexed ATM cells.
