Introduction of HDMI

  1. 1. Introduction of HDMIWhat is HDMI?HDMI (High-Definition Multimedia Interface) is a compact audio/video interface fortransferring uncompressed digital audio/video data from an HDMI-compliant device ("thesource device") to a compatible digital audio device, computer monitor, video projector, ordigital 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 beused for any uncompressed TV or PC video format, including standard, enhanced, highdefinition, and 3D video signals; up to 8 channels of compressed or uncompressed digitalaudio; 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, andimplementations of the VESA EDID.Cost of HDMIHDMI 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 alsoimplemented. An alternative fee for HDMI manufacturers making less than 10,000 units peryear is an annual fee of $5,000 with a royalty rate of $1 per unit. The royalty only applies tofinal products and does not apply to products that are included in, or with, a licensed HDMIproduct that is already subject to the royalty. An example is that a HDMI cable sold directly toconsumers is paid for by the hdmi cable manufacturer but if the cable manufacturer sells theHDMI cable to a HDTV manufacturer that includes it with an HDTV subject to the royalty thenthe HDTV manufacturer pays only the royalty on the HDTV.Guide of Buying HDMI CableWhich store has the best deals?
