HDMI sounds off over DVI

摘要

Anew digital interface for DTV sets and related devices was introduced last week by a consortium of consumer-electronics manufacturers and Hollywood studios that believe it's a step toward securing digitally distributed TV content. Called HDMI (the acronym stands for High Definition Multimedia Interface), the technology is based on the already existing Digital Visual Interface (DVI), which was designed by chip maker Silicon Image to transmit uncompressed digital video images to flat-panel PC monitors. The HDMI interface adds eight channels of audio to the interface, meaning that DTV sets and related devices could send both video and audio signals through one connection.
