What is: UMD, HDMI, and VGA?

Answer 1

UMD (Universal Media Disc )– the new mobile entertainment era
UMD is the new high-capacity optical medium designed for the high speed and efficient delivery of digital entertainment content, including game, movies and music. The newly developed UMD is the next-generation compact storage media. At only 60mm in diameter, the UMD can store up to 1.8GB of digital content, making it perfect for the portable entertainment player PSP. So hit the street with UMD!


HDMI (High-Definition Multimedia Interface) is the first industry-supported, uncompressed, all-digital audio/video interface. HDMI provides an interface between any audio/video source, such as a set-top box, DVD player, and A/V receiver and an audio and/or video monitor, such as a digital television (DTV).

HDMI supports standard, enhanced, or high-definition video, plus multi-channel digital audio on a single cable. It transmits all ATSC HDTV standards and supports 8-channel digital audio, with bandwidth to spare to accommodate future enhancements and requirements.


Video Graphics Array (VGA) a graphics display system for PCs developed by IBM. VGA has become one of the de facto standards for PCs. In text mode, VGA systems provide a resolution of 720 by 400 pixels. In graphics mode, the resolution is either 640 by 480 (with 16 colors) or 320 by 200 (with 256 colors). The total palette of colors is 262,144.

Unlike earlier graphics standards for PCs -- MDA, CGA, and EGA -- VGA uses analog signals rather than digital signals. Consequently, a monitor designed for one of the older standards will not be able to use VGA.

Since its introduction in 1987, several other standards have been developed that offer greater resolution and more colors (see SVGA , 8514/A graphics standard, and XGA), but VGA remains the lowest common denominator. All PCs made today support VGA, and possibly some other more advanced standard.

HDMI... (High Definition Multimedia Interface) is a specification that combines video and audio into a single digital interface for use with digital versatile disc (DVD) players, digital television (DTV) players, set-top boxes, and other audiovisual devices. The basis for HDMI is High Bandwidth Digital Content Protection (HDCP) and the core technology of Digital Visual Interface (DVI). HDCP is an Intel specification used to protect digital content transmitted and received by DVI-compliant displays...

VGA....The term display mode refers to the characteristics of a computer display, in particular the maximum number of colors and the maximum image resolution (in pixels horizontally by pixels vertically). There are several display modes that can be found in personal computer (PC) systems today.
