Digital video can be transmitted from a source, such as a DVD player, video receiver, ATSC tuner, or other computer, to a display, such as a flat panel video monitor, using a protocol known as Digital Visual Interface (DVI). However, DVI does not envision processing audio data. Accordingly, to extend communication protocols to digital multimedia that includes audio for the purpose of, e.g., playing digital movies and the like, a protocol known as High Definition Multimedia Interface (HDMI) has been developed. HDMI (High Definition Multimedia Interface) is a transmission interface developed for the next generation multimedia audio video systems including the DVD players, game box converter, TV box, and etc. Because HDMI is practical for transmitting digital data without compression, it effectively reduces signal interference and attenuation due to conversion between digital signal and analog signal. HDMI is similar to DVI except it envisions the use of audio as well as video data and it adds television-related resolutions. HDMI provides the best quality and high fidelity video signal for consumer AV products, and because it supports all kinds of transmission format of digital video signal, resulted in less cable and smaller connector for the transmission of uncompressed data. Both DVI and HDMI are intended for wired transmission, and HDMI further permits the encryption of digital multimedia using an encryption method known as High-Bandwidth Digital Content Protection (HDCP). DVI connection transmits only image information (i.e., video and synchronous signals) while HDMI provides extra function to transmit multi-channel digital audio signals disregarding the transmission and receiving are done in compression format or not. DVI also supports HDCP as an optional characteristic. An HDMI cable assembly generally comprises an insulative housing having a plurality of passages, a plurality of contacts disposed in the housing, a shielding shell surrounding the housing, a cable consisting of a plurality of conductors terminated to the contacts and an insulated protecting cover molded over joint portions of the cable and the contacts. HDMI simplifies the complicated installation of A/V cables of the current home entertainment system by replacing one HDMI cable to exit the conventional eleven A/V cables.
