The Differences Between HDMI Cables
An HDMI (High-Definition Multimedia Interface) is an interface designed for the purposes of transferring digital information. Instead of using the analog standards including radio frequency, VGA, and other formats, HDMI is the digital alternative. Audio/video sources are connected by HDMI to additional digital audio devices like televisions and monitors. HDMI is compatible with signals from the Digital Video Interface (DVI), and luckily no conversion needs to take place; and most importantly, no loss of quality occurs, as long as a DVI-to-HDMI box is used.
Of course there are at least four different HDMI versions to choose from, so it makes sense to explore some of these differences: HDMI 1.0 was created in 2002, and it is a single-cable interface that operates with the bandwidth of 4.9 Gbit/s, but it handles only 3.96 B/bits of video and an 8-channel LPCM/192 KHz/24-bit audio. 1.2 Version came in 2005, giving support to the one-bit audio of eight channels; it also allowed more flexibility for PCs.
Version 1.3 came along in 2006 offering more bandwidth up to 340 MHZ, while supporting 30-bit, 36-bit, 48-bit, YCC, and sRGB color compared to only the earlier versions. In addition, the CEC limits were altered, and the commands were brought back-but slightly changed. That same year, three more 1.3 versions came out offering no more features, but just descriptions of products.
Version 1.4 came out in 2009 increasing the resolution and adding an Ethernet allowing for 100 MB/s between HDMI instruments. There is also an audio return channel added to the latest version. Moreover, stereoscopic 3D is added as the field alternative.
Basically, the versions of HDMI maintain a variety of types that match each specific; each version is numbered as described above, and with each new version, the bandwidth increases as well as the amount that can actually be transferred over the cable. Various products that claim to have HDMI features may not support the latest technology because many of those features are optional, and much of the advertising will not clearly define the available options. As far as connector types are concerned, there are four kinds: A and B, which go along with the HDMI 1.0 version, while type C coincides with the 1.3 version, and lastly D is coupled with the 1.4 version. The quality of cable is based on the construction, and there are cables designed for standard purposes and other cables created for high-speed interface.
