Definition of Terms

HDMI

HDMI(High Definition Multimedia Interface) is a new connection format that supports both video and audio on a single digital connection.

The HDMI connection carries uncompressed, standard or high definition digital video signals and multi-channel audio signals to AV components such as HDMI equipped TVs, in digital form without degradation.

Since the video signals from HDMI jack are compatible with the current DVI(Digital Visual Interface) format, HDMI jacks can be connected to DVI jacks by way of an HDMI-DVI converter cord. The HDMI specification supports HDCP(High- bandwidth Digital Contents Protection), a copy protection technology that incorporates coding technology for digital video signals.

HDCP

HDCP(High-bandwidth Digital Content Protection) is a specified method from Intel for protecting copyrighted digital entertainment content that uses the Digital Video Interface (DVI) by encrypting its transmission between the video source and the digital display (receiver). The video source might be a computer, set-top box, or digital versatile disc (DVD) player, and the digital display might be an liquid crystal display (LCD), television, plasma panel, or projector.

DVI

DVI(Digital Video Interface) is a specification created by the Digital Display Working Group(DDWG) to accommodate analog and digital monitors with a single connector. There are three different DVI configurations : DVI-A, designed for analog signals, DVI-D, designed for digital signals, and DVI- I(intergrated), designed for both analog and digital signals.

Using a DVI connector and port, a digital signal that is sent to an analog monitor is converted into an analog signal. If the monitor is a digital monitor, such as a flat panel display, no conversion is necessary. Many monitors now include a DVI connection and many video adapters include a DVI port along with, or instead of, the traditional 15-pin Video Graphics Array (VGA) port.

Component Video

Video signals with three channels of separate information that makes up the picture. There are some types of component video, such as Y/CB(PB)/CR(PR) and R/G/B.

Dolby Digital

Dolby Digital provides multichannel surround sound in cinemas from 35mm film and in the home from laser discs, DVDs, and digital broadcast television, cable, and satellite systems. It enables the transmission and storage of up to five full-range audio channels, plus a low-frequency effects channel(LFE), thus 5.1 channels, in less space than is required for just one linear PCM-coded channel on a compact disc.

DTS

DTS(Digital Theater Systems) is a newly-developed surround system which can handle more amount of data, providing better audio quality. Though the number of audio channels is 5.1 which is same as

Dolby Digital, discs bearing the " " provides fat sound and better signal-to-noise ratio, thanks to the lower audio compression ratio format. It also provides wide dynamic range and better separation, resulting in magnificent sound.

Bitstream

The digital signal form of multichannel audio data (e.g., 5.1 channel) before it is decoded into its various channels.

Linear PCM

PCM stands for Pulse Code Modulation. Linear PCM is the usual digital method without compression, used for audio playback of audio CDs, DVD Videos, etc.

Packed PCM

A lossless compression system that enables more PCM audio to be stored on a DVD-Audio disc than would otherwise be possible.
