HD is the term used to differentiate the systems that generate, transmit or support HD content (High Definition) with those of standard definition or low definition (SD).

HD resolutions are usually at least 1280 x 720 pixels by taking the ratio "width x height". Being the height, 720 pixels, which make high resolution.

The HDV term that stands for "High Definition Video" is a video format that appeared in 2003 and is widely used until today. There are two types within the concept "HDV": the HDV1 and HDV2

HDV-1 is a format that records images at 720p (p for progressive) under native resolution of 1280x720 pixels.

HDV-2 is based on images at 1080i (interlaced) under native resolution of 1440x1080 pixels.

PVC (Polyvinyl chloride) is extracted from the polymerization of the vinyl chloride monomer. We can classify PVC into two large groups: rigid PVC and flexible PVC.

Rigid: used for the construction of pipes, pipes, containers, tool accessories, parts, blinds, windows, etc.
Flexible: Corrugated tube, traffic signals like cones. irrigation hoses, curtains for refrigerators, footwear, medicina, etc.

This material begins to soften at 80 ° C and to get rid at 140 ° C. Thanks to these and other properties, PVC is a recyclable material.

Among the main features of PVC we find:

• Different degree of hardness.
• Waterproof.
• It does not corrode.
• It is modelable if subjected to high temperatures.
• Good electrical insulation.
It is a very materialessential
• Stable and inert.
• Good mechanical resistance and impact.
• High resistance to abrasion.
• Resistant and lightweight
• Good thermal insulation
• It is odorless, tasteless and innocuous.

The BNC connector is a connector type, quick connect/disconnect, incoporando more security connector for coaxial cable. Initially designed as a miniature BNC Connector Type C is a type of connector used with coaxial cables like RG-58 and RG-59 RF applications that required a quick connector, suitable for UHF and constant impedance to over a wide range.

Serial Digital Interface or SDI is also called a family of digital video interfaces standardized by SMPTE. Data rate: 1.485 Gbit/s
