몰렉스 제품이며 단자외부 고무틀의 모양은 변경될 수 있습니다.
실리콘이미지, 히타치, 마쓰시타, 소니, 도시바, 톰슨, 필립스 등이 가전제품을 위한 새로운 인터페이스 규격인 고선명 멀티미디어 인터페이스(HDMI:High Definition Multimedia Interface) 워킹그룹을 구성하고 두 달 후 HDMI 0.9 규격을 발표했다. 이 규격은 고선명 비디오와 다중채널 오디오를 단일 디지털 인터페이스로 통합할 수 있게 해준다. HDMI가 DVI와 다른 점은 크기가 더 작고 HDCP 암호기능이 내장됐으며 다중채널 오디오를 지원한다는 것이다.
이처럼 DVI-HDTV 규격이 DVI 인터페이스를 가전제품에 채용하게 한 반면 HDMI 규격은 DVI를 오디오 및 비디오 가전제품에 채용할 수 있는 길을 터놓았다. HDMI의 가장 큰 매력은 디지털 오디오와 비디오를 모두 지원함으로써 유선으로 연결하지 않고서도 가정 오락기기 시스템을 구성할 수 있게 한다는 것이다.
HDMI는 최고 5 기가비트/초의 대역폭을 가진 단일, 완전 디지털 인터페이스에 고화질 비디오와 멀티채널 오디오를 결합하고 있다. HDMI가 가진 주요 이점들은 압축되지 않은 디지털 품질, 케이블선 사용의 축소, 광범위한 종류의 CE 부품들에 적합한 사용자 친화적인 소형 커넥터를 포함한다. HDMI는 또한 기기들간의 양방향 통신을 지원하기 때문에 DTV로 하여금 영상을 최고 수준으로 제공하는 방법을 지능적으로 결정할 수 있게 해준다. HDMI는 지난 2003년 1월에 발표된 이래 30개 이상의 기업들이 HDMI v 1.0 표준 채택업체들이 됐다.
HDMI는 또한 2003년 6월 26일 가전 기기간의 HDMI 디지털 인터페이스를 규정하는 사양서 초안인 0.9 버전을 발표하였다. 이 HDMI Compliance 테스트 규격 0.9는 HDMI 설립 기업들이 HDMI 제품 인증을 확인하기 위한 테스트, 절차, 장비 규격 등을 포함하고 있다. HDMI 호환성 테스트는 HDMI 범주의 제품들을 HDMI 공인 인증 센터에 제출하도록 하고 있는 데, 이 범주는 소스 (DVD, set-top box등), 싱크(digital TV등), 리피터 (A/V 수신기등) 과 케이블 4 종류이다. 2003년 발표이후, 현재 30개 이상의 기업이 HDMI v 1.0 규격을 채택하였다고 HDMI측은 밝히고 있다.
2. HDMI의 특징
HDMI (High Definition Multimedia Interface)는 압축을 하지 않는 모든 디지털 오디오/비디오 인터페이스로서 셋탑박스, DVD 플레이어 등의 오디오/비디오 소스 및 디지털 TV와 같은 플레이어 간의 인터페이스를 제공한다. HDMI는 단일 케이블에서 표준의 high-definition 비디오와 멀티 채널의 오디오를 지원하며, 모든 ATSC HDTV 표준과 8채널 디지털 오디오를 지원하여 미래의 확장을 위한 여지를 마련하고 있다.
HDMI 설립 기업은 가전 기기 제조 기업인 Hitachi, Matsushita Electric Industrial (Panasonic), Philips, Sony, Thomson (RCA), Toshiba, 과 Silicon Image 등이며 Intel은 High-bandwidth Digital Content Protection (HDCP) 을 HDMI에 제공하고 있다. 또 HDMI는 Fox와 Universal, 그리고 시스템 운영 기업인 DirecTV, EchoStar (Dish Network), CableLabs의 지원을 받고 있다.
HDTV 시그널을 최대의 해상도를 전송하기 위하여서는 2.2Gbps를 필요로 하는데 HDMI는 이것은 IEEE 1394 의 규격을 훨씬 넘어서므로(5Gbps) HDMI가 미래의 표준이 될 것이라고 HDMI측은 밝히고 있다. 더구나 5Gbps중 HDTV 용도로는 50%도 채 사용하지 않기 때문에 다른 미래의 기술을 수용할 여력이 있다는 점도 HDMI 에서 큰 특징으로 삼고 있다.
3. HDMI의 전망
HDMI는 DVI에 기반하고 있으며, 현재 업계에는 DVI와 IEEE 1394가 경쟁하고 있다. DVI는 1999년에 Compaq, Fujitsu, Hewlett-Packard, IBM, Intel, NEC, Silicon Image 등이 Digital Display Working Group을 설립하면서 시작되었다. DVI는 최초에는 PC와 LCD모니터간의 연결을 위하여 개발되었고, 현재까지 이 분야에서 가장 많이 사용되고 있다. IEEE 1394는 Apple에서 PC 와 주변기기간의 연결을 위하여 연구한 것이 시초로 1990년대 중반에 AV/IT를 모토로 엔터테인먼트 전략을 구사하던 Sony가 자사의 멀티미디어 PC인 VAIO등에 장착하면서 보급되기 시작하였고, 일본 가전 업계를 중심으로 가전 기기간의 인터페이스의 표준으로 정립되고 있는 HAVi의 기본 인터페이스로 설정되는 등 업계의 지지를 확대하고 있다.

Does HDMI accommodate long cable lengths?
Yes. HDMI technology has been designed to use standard copper cable construction at long lengths. In order to allow cable manufacturers to improve their products through the use of new technologies, HDMI specifies the required performance of a cable but does not specify a maximum cable length. Cable manufacturers are expected to sell reasonably priced copper cables at lengths of up to 15 meters. As semiconductor technology improves, even longer stretches can be reached with fiber optic cables, and with active cable technologies such as amplifiers or repeaters.
When will HDMI cables be available?
Due to the rapid adoption of HDMI among CE manufacturers and the demand we are seeing from end-customers, HDMI Licensing, LLC is in active discussions with cable manufacturers about supplying the retail channel with HDMI cables. Since the vast majority of the market requires 5m and shorter cables, we expect manufacturers to make these cables available first. We do expect some manufacturers to market 5-15m (and beyond) HDMI cables as the market dictates and on a more limited basis. We will post this information on the HDMI website as it becomes available.
