Abstract

디지탈 방송 송수신장치가 제공된바, 시청자가 방송국에 요금을 납부하고 시청권한을 획득하여야만 화면시청을 할 수 있으며, 비가입자는 전혀 시청을 할 수 없도록 하여 디지탈 방송서비스가 새로이 시작되어 시청자수를 늘려가고자 할 때에는 문제가 발생되고, 가입을 미루고 다른 시청자들의 평가 또는 대중매체의 평가를 기다릴려고 할 것이므로 시청자수를 지속적으로 급격히 확대하기가 매우 어려운 문제점이 발생되는 것을 해결하기 위하여 방송되는 프로그램을 디스크램블러를 장착한 가입자가 월시청료만으로 시청가능한 제1프로그램 형태, 그리고 디스크램블러를 장착한 가입자만이 시청가능하며 프로그램별로 요금이 부과되는 제2프로그램 형태뿐만아니라, A/V디코더 만으로 시청이 가능하며 무료인 제3프로그램 형태로도 방송을 하여 A/V 디코더를 갖는 비가입자는 상기 제3프로그램 형태만을 시청가능하게 하며, 정규 가입자는 모든 프로그램을 시청가능하도록 하는 것이다. 따라서, 본 발명에 따른 디지탈 방송 송수신장치는 비가입자에게 새로운 방송서비스를 시험 사용할 수 있는 기회를 부여하여 프로그램 시청가입을 촉진시키고, A/V 디코더의 판매 역시 촉진시킬 수 있도록 한 것이다.Digital broadcasting transceiver is provided, so that viewers can watch the screen only when they pay a fee to the broadcasting station and obtain the viewer's authority, and the non-subscriber cannot watch at all, and the digital broadcasting service is newly started to increase the number of viewers. In order to solve the problem that it is very difficult to continuously expand the number of viewers because it will cause problems, delay the subscription and wait for the evaluation of other viewers or the media. The first type of program that can be watched by the subscriber only with the monthly fee, and the second type of program that can be watched only by the subscriber equipped with the descrambler. A / V by broadcasting in 3rd program form Ratio of particles having a coder and to enable only the third-view type program, a regular subscriber to enable viewing of all programs. Accordingly, the digital broadcasting transmission and reception apparatus according to the present invention provides a non-subscriber with an opportunity to try out a new broadcasting service to promote subscription to a program and to promote the sale of an A / V decoder.
