HDCP (acronym for high-bandwidth digital content protection in English, that means protection of digital content of high bandwidth) is a specification developed by Intel to control the content of digital audio and video that is transmitted through DisplayPort, DVI connections, HDMI, Gigabit Video Interface (GVIF), or Unified Display Interface (UDI). The specification is proprietary, and their implementations must be licenciadas, of which Digital Content Protection is responsible. It is a type of digital rights management.

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.

AWG stands for "American Wire Gauge". It's used to represent measures of cable length and section.

This is an AWG conversion table:
