INTRODUCTION TO HDMI
HDMI (High-Definition Multimedia Interface) is a compact audio/video interface or a connector for transmitting uncompressed digital data. By delivering crystal-clear, all-digital audio and video via a single cable, HDMI dramatically simplifies cabling and helps provide consumers with the highest-quality home theater experience.
Composite Video
An analog television (picture only) signal modulated onto an RF carrier.
Contains all required video information, It is a composite of three source signals called Y, U and V with sync pulses. Y represents the brightness or luminance of the picture and includes synchronizing pulses, so that by itself it could be displayed as a monochrome picture. U and V represent hue and saturation or chrominance; between them they carry the color information
Separate video/S-Video
An analog video transmission scheme.
Video information is encoded on two channels: luma (luminance, intensity) and chroma (color).
The luminance (Y; gray-scale) signal and chrominance (C; color) information are carried on separate, synchronized signal and ground pairs
OVERVIEW OF HDMI
An Interface acts as medium of interaction or communication between any two devices. It's a single cable and user-friendly connector that replaces the maze of cabling behind the home entertainment center.
It’s the one cable that transmits digital video, digital audio, and control data through a single high-speed link, making it the best and easiest way to turn your TV into a home entertainment powerhouse. HDMI provides an interface between any A/V source, such as a set-top box, Blu-ray Disc players, DVD player, personal computers (PCs), video game consoles (such as the PlayStation 3 and Xbox 360), and AV receivers such as compatible digital audio devices, computer monitors, video projectors, and digital television(DTV) over a single cable.
WHAT ARE HDTVS?
High- definition television (or HDTV, or just HD) refers to video having resolution substantially higher than traditional television systems (standard-definition TV, or SDTV, or SD). HD has one or two million per frame, roughly five times that of SD. Early HDTV broadcasting used analog techniques, but today HDTV is digitally broadcast using video compression.
CONCLUSION
HDMI technology is the global standard for connecting high-definition products: the uncompressed, all-digital interface that delivers both dazzling quality and unmatched ease of use. HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transmitting uncompressed digital data. It's a single cable and user-friendly connector that replaces the maze of cabling behind the home entertainment center.
HDMI connects digital audio/video sources—such as set-top boxes, Blu-ray Disc players, personal computers (PCs). HDMI (High-Definition Multimedia Interface) is today the best kind of digital audio and video connector available that promises to replace all connectors currently used by players, cable/satellite decoders, TV sets, video projectors and video monitors
