Balun (bal anced) to (un balanced) Component Video DVI Digital Audio (SPDIF) Calrad 55-500 , 55-715, 55-716 Series cables HDMI (High-Definition Multimedia Interface) Calrad 55-626, 627 Series cables This is a connection standard that was first developed by Hitachi, Panasonic, RCA, Silicon Image, Sony, and Toshiba in 2002. HDMI is quickly emerging as the connection standard for HDTV in the consumer electronics market. With 19 wires wrapped in a single cable that resembles a USB wire, HDMI is the first and only digital interface that is able to combine uncompressed audio and video over a single cable. Possessing a bandwidth of 5 Gbps, transmissions over HDMI are currently using less than half of that. This leaves plenty of room to expand the technology in the future. HDMI is fully backwards compatible with DVI, and will supplant it as the interface of choice over the next few years. As a rule, HDMI cables should not run longer than 15 feet (5 meters), or degradation of the signal could can occur, Calrad has designed special cables and active in-line amplifiers to push the distance out to 150 ft., see our 55-626A infline amplifier for more details. HDCP is a form of Digital Rights Management (DRM) developed by Intel Corporation to control digital audio and video content as it travels across Digital Visual Interface (DVI) or High-Definition Multimedia Interface (HDMI) connections. The specification is proprietary , and creating an implementation of HDCP requires a license . HD-SDI High Definition Serial Digital Interface, (Non HDCP signal) This standard transmits audio and video over a single coaxial cable with a data rate of 1.485 Gbit/s, typically used in the broadcast field and not by consumers. HDTV (High Definition Television) High-Definition Television. The high-resolution subset of our DTV system. The ATSC defines HDTV as a 16:9 image with twice the horizontal and vertical resolution of our existing system, accompanied by 5.1 channels of Dolby Digital audio. The CEA defines HDTV as an image with 720 progressive or 1080 interlaced active (top to bottom) scan lines. 1280:720p and 1920:1080i are typically accepted as high-definition scan rates.
