The High-Definition Multimedia Interface (HDMI) is a compact audio/video interface for transmitting uncompressed digital signal/data. It provides alternative digital options to consumer analog cables such as coaxial cable, Radio Frequency (RF), composite video, S-Video, SCART, component video, D-Terminal, VGA and so on. Nowadays, HDMI is widely used on connecting digital audio/video sources such as set-top boxes, digital multimedia players, Blu-ray Disc players, video game consoles, AV receivers and computer display cards etc. to compatible LCDs, Computer Monitors, digital audio devices, and digital televisions.

HDMI supports standard, enhanced or high-definition video format, along with up to 8 channels of digital audio on a single cable to any TV or PC (with 10.2 Gbps of bandwidth). It is independent from various digital television standards such as ATSC and DVB, as these video streams can be decoded and output as uncompressed video stream on HDMI.

HDMI products have started shipping in autumn 2003. Over 800 Consumer Electronics and Computer companies have adopted the HDMI specification/guideline set by the HDMI founders, as HDMI Adopters. D&S Cable is proud to present ourselves as one of the adopters by the HDMI founders.

The HDMI lastest version is HDMI1.3a. HDMI1.3a includes the following new features:

• Higher speed - 10.2 Gbps
  - Deep Color - increasing the color depth from millions to billions of colors.
  - Higher resolutions - over 400% greater resolution than 720p HDTV, 1080P HDTV, up to 1440P.
  - High frame rates - higher refresh rates (up to 120 Hz) for smoother motion

• New lossless audio formats
  Support Dolby®TrueHD and DTS-HD Master Audio

Lip sync correction
  HDMI 1.3 incorporates an automatic audio/video syncing capability that allows devices to perform this synchronization
  automatically with accuracy

• New mini connector
  Type C connector introduced for portable devices such as camcorders and digital cameras

• Deep Color support
  HDMI 1.3 supports 30-bit, 36-bit and 48-bit (RGB or YCbCr) color depths, up from the 24-bit depths in previous versions of the
  HDMI specification

• Broader color space
  Supports the next-generation "xvYCC" color space. It is 1.8 times as many colors as existing HDTV signals
2. DisplayPort

DisplayPort(DP) is a newly used digital display interface standard guided by the Video Electronics Standards Association (VESA). DP was first approved on May 2006. The latest version 1.1a was released by VESA for April 2, 2007.

Displayport is defined as a new, high-definition digital audio/video interconnect for computing displays, graphic cards, and laptops.

With a 34% PCs market penetration forecast in 2010, Displayport is expected to replace DVI and VGA, or even the HDMI equivalent for computers systems.

DisplayPort supports the following features:
• Support a maximum of 10.8Gbit/s and 2560 x 1600 resolutions
• Support a minimum of 1080p resolution at 24bpp, 50/60 Hz over 4 lanes at 15 meters
• Provide both digital video and audio in one cable
• Support industry standard colorimetry specifications for consumer electronics devices including RGB and YCbCr 4:2:2 and
  YCbCr 4:4:4
• Support up to 8 channels of LPCM coded audio at 192 kHz with a 24 bit sample size
• Composites of smaller connector footprint than either DVI or VGA
• Support HDCP(High-Definition Content Protection) which uses 128-bit AES encryption
• Support hot plug and un-plug detection and link status-failure detection
• Support the 1Mbps bidirectional auxiliary channel
