HDMI (High-Definition Multimedia Interface) is an audio/video interface that transfers uncompressed digital audio and video from devices like Blu-ray players to displays like TVs or monitors. It supports standard, high definition, and 3D video as well as compressed or uncompressed audio through a single cable. HDMI implements industry standards for video formats, audio transmission, and device communication. Manufacturers pay annual fees and royalties depending on production volume to license the HDMI technology and logo. Cheap HDMI cables are sufficient for digital video and audio transmission as long as they are reliable, and extra features like gold-plating do not improve signal quality.

1. Introduction of HDMI
What is HDMI?
HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for
transferring uncompressed digital audio/video data from an HDMI-compliant device ("the
source device") to a compatible digital audio device, computer monitor, video projector, or
digital television. HDMI is a digital replacement for existing analog video standards.
There are a number of HDMI-standard cable connectors available, each of which can be
used for any uncompressed TV or PC video format, including standard, enhanced, high
definition, and 3D video signals; up to 8 channels of compressed or uncompressed digital
audio; a CEC (Consumer Electronics Control) connection; and an Ethernet data connection.
HDMI implements the EIA/CEA-861 standards, which define video formats and waveforms,
transport of compressed, uncompressed, and LPCM audio, auxiliary data, and
implementations of the VESA EDID.
Cost of HDMI
HDMI manufacturers pay an annual fee of US$10,000 plus a royalty rate of $0.15 per unit,
reduced to $0.05 if the HDMI logo is used, and further reduced to $0.04 if HDCP is also
implemented. An alternative fee for HDMI manufacturers making less than 10,000 units per
year is an annual fee of $5,000 with a royalty rate of $1 per unit. The royalty only applies to
final products and does not apply to products that are included in, or with, a licensed HDMI
product that is already subject to the royalty. An example is that a HDMI cable sold directly to
consumers is paid for by the hdmi cable manufacturer but if the cable manufacturer sells the
HDMI cable to a HDTV manufacturer that includes it with an HDTV subject to the royalty then
the HDTV manufacturer pays only the royalty on the HDTV.
Guide of Buying HDMI Cable
Which store has the best deals? Which Web site has the best selection? Which cable is right
for your TV?
Cheap cables will produce the exact same picture and sound quality as expensive cables.
Check out our HDMI cable trilogy: "Why all HDMI cables are the same," "Why all HDMI
cables are the same," and "why all HDMI cables are the same." all these questions, none of
we could tell the difference. The fact is, HDMI is digital, meaning you either get the feed or
you don't. High prices and gimmicks like gold-plating don't affect 1s and 0s. Our advice: Find
a reliable cable assembly supplier, purchase your wiring online for cheap, and use the saved
money to upgrade to a larger flat screen.
www.china-wireharness.com offers a wide range of wires and cables, including wire
harness/wiring harness, USB cable, HDMI cable, flat cable, ribbon cable and so on.
