HD CABLING & NETWORKING

HDMI FACTS

HDMI can pass video resolutions from 480i up to 2160p. However, each manufacturer determines the parameters for what is to be transferred via HDMI in their components.

HDMI can be implemented on Televisions, AV Receivers, DVD Players, Blu-ray Disc Players, HD-DVD Players, HD Cable Boxes, and HD Satellite Boxes.

HDMI also includes provisions for HDCP (High Definition Copy Protection). This allows content providers to prevent their programming from being illegally copied.

HDMI can be adapted to DVI (Digital Video Interface), via adapter cable or connector. However, the device that has the DVI connection must be HDCP enabled for the signal transfer to work.

There are several versions of HDMI that have been developed over the years. In each case the physical connector is the same, but the content characteristics have evolved. Depending on when you purchased an HDMI-enabled component (HDTV, DVD player, Blu-ray Disc player, etc...) would determine what HDMI version you have. All newer versions are backwards compatible. You can still use newer versions of HDMI with components equipped with older versions, you just won't be able to access the all the content features of the newer version(s).

HD RESOLUTION

The video quality of an image on a TV screen is measured in lines of resolution. High definition is a term that describes a resolution of at least 1,280 horizontal lines by 720 vertical lines and can be as high as 1,920-by-1,080 lines. The images are also broadcast using either a progressive-scan or interlaced format which, when paired with the vertical resolution, creates the shorthand terms of 720p, 1080i,1080p and 2160p (4K or UHD), with 2160p delivering the highest resolution.


NATIVE RESOLUTION

Every HDTV set has a native resolution specification, which is the maximum resolution possible based on the number of pixels the screen contains. Some HDTVs have a native resolution of 720p, while others, including the majority of models in stores today, offer 1080p capability. Also, the HDTV must be connected via HDMI cable to enable the highest-quality video and sound possible.


Using the wrong cables or cabling your home network incorrectly will affect your entire home entertainment setup and impair the overall HD (High Definition) picture and sound quality.


It is crucial that you use the correct cable and consider the impact of distance when connecting your home network to receive and transmit HD signal.  We use advanced cables and equipment to calibrate your home network to ensure that you have either zero loss or minimal loss over your HD distribution network.


HD Networking is possible either by cabling your home with HDMI cable or using “traditional” network cable which is used in most offices (Cat5 or Cat6). HDMI cable has limitations on distance and ability to network multiple points in a large home, therefore Cat5 or Cat6 cable along with “converter boxes” are necessary to professionally distribute your HD signal in your home.


To transfer the digital video signal from a source to a TV, the source must convert the signal from digital to analog, this results in some information loss. However, an HDMI (High Definition Multimedia Interface) output can transfer a digital video source signal (such as from a DVD player) digitally, without conversion to analog. This results in a pure transfer of all of video information from the digital video source to a HDMI or DVI (via a connection adapter) equipped TV. In addition, HDMI can transfer both video and audio signals
