| The HDMI cables that connect the signal generating device (BluRay players, computers, DVB-T or HDTV receivers, etc.) to the TV set are not ordinary analog signals like SCART cables. They are actually data cables that carry digital signals along the various wires that make up them. To function properly, an HDMI cable must meet standards that are classified according to a certain ""Category"". The quality standards for this type of cable are little known to professionals and end users alike. Using the acronym ""HDMI"" should oblige to meet the requirements of the whole specification data list, so it would be a mistake to equate it with only one connection method. The lack of information and the fact that such cables are used in household appliances makes it easier to distribute them on the market without meeting the quality required by the regulations. Users purchasing an HDMI cable should know that: Despite the existence of the HDMI specification, there is still no obligation in Europe to ban the use of non-compliant products, so the high quality of HDMI cables is only ensured if it is certified by laboratories such as Televés. What distinguishes an HDMI cable? The type of material and method of manufacture play an important role in the manufacture of the cable, especially for the inner conductors and the outer sheath. Below are some aspects that will help us judge the quality of the product: Inner conductor: The HDMI standard indicates that the cable should be multi-core. This type of cable ensures compliance of electrical measurements, while ensuring the flexibility of the cable, which allows it to retain its function despite its installation in tight places. There are many cables on the market equipped with single-wire conductors, resulting in significant cost savings, but a significant reduction in the functions achieved. In addition, there are cases where copper clad steel or other low quality alloys that fail the attenuation, ""jitter"", etc. tests are used in place of copper conductors. According to the standard, the number of pins should be 19. Some manufacturers, regardless of the conditions of the standard, produce cables consisting of 15 pins, which in the future will limit the use of the cable to other applications. The cables should be twisted and have a shielded braid. As with any type of cable, these two components help to avoid problems such as diaphony or signal coupling between pairs. In the absence of shielding, the installation using the HDMI cable will not comply with the CE directive, so it would be unreasonable to sell cables without shielding in Europe. Outer sheath: One of the most important aspects of assessing the quality of an outer casing is compliance with the RoHS directive. Violating the rules means that the cable is both polluting and harmful to the environment. The presence of excessive wrinkles and folds increases the risk of the protective sheath breaking, so that the cable will lose its properties. Why Choose Televes HDMI Cables? All Televes HDMI cables have high physical characteristics and techniques that ensure the performance of the cable according to the rules.
