Abstract

본 발명은 디지털 케이블 세톱 박스(ㅇigital Cable Settop Box) 기능과 인터네트 웹 터미널(Internet Web Terminal) 그리고 각종 CD(Compact Disc) 및 DVD(Digital Video Disc) 등의 타이틀을 재생하도록 하기에 적합하는 통합 멀티 미디어 재생 및 단말 장치에 관한 것으로서, 본 발명에서는 종래의 디지털 케이블 세톱 박스와 모뎀을 이용한 인터네트 웹 터미널 기능 그리고 DVD 롬 재생기를 통합하여 케이블을 통한 디지털 케이블 세톱 박스 기능과 전화선의 모뎀을 이용한 인터네트 웹 터미널 그리고 CD 비디오 게임, 오디오 CD, 비디오 CD, 포토 CD, DVD 등의 타이틀을 통합 재생할 수 있도록 함으로써 멀티 미디어의 이용이 더욱 용이해 지는 것이다.The present invention provides an integrated multi cable suitable for playing titles such as a digital cable settop box function, an internet web terminal, and various compact discs and digital video discs. The present invention relates to a media playback and terminal apparatus, and more particularly, to an Internet web terminal function using a conventional digital cable set-top box and a modem, and a digital cable set-top box function through a cable by integrating a DVD ROM player and an internet web terminal using a modem of a telephone line. In addition, by enabling titles such as CD video games, audio CDs, video CDs, photo CDs, DVDs, and the like, the use of multi-media becomes easier.
