"I no longer use coaxial because my signal is high definition, it is obsolete and I prefer to install category 6 cable", this is one of the statements that I have come across the most in the audio and video industry.Good morning dear readers, thank you very much for taking a few minutes to read this week's column on coffee and technology.How was the bridge?And how is your short week going? I feel like I missed days after Monday's holiday.With the entry of video extenders to the market, as I remember it must have been about 10 years ago, by the way, the first ones required two cat5 cables to extend a signal up to 30 meters;Most of the video networks began to be designed on cat5, later it evolved to a video network over IP, which works as a video "matrix" over a network protocol (IP's).However, video distribution can also be done through a coaxial cable network (RG6), this does not mean that it is obsolete because the signal that travels in the cable is high definition.Do you remember the analog blackout? Well, this blackout referred to the fact that the signal that was used for open television (NTSC) for many years was replaced by a digital signal (ATSC), which is why we local channels can tune in FullHD and we identify them as channels such as: 10.1, 12.2, etc.In the same way, it is possible to convert a signal that is delivered by HDMI to a digital RF signal and that travels through a coaxial cable, in this way, being able to distribute the audio and video digitally and in high definition, this means that no there are losses in signal quality.we identify this signal by the type of connector, BNC (special connector that has a lock to prevent disconnection from the equipment);this signal also travels through coaxial cable.In conclusion, the coaxial cable is still valid for distribution and transmission of high definition video and depending on the project, it can be a good alternative to solve a project.I wish you an extraordinary weekend in the company of family and friends.This is an opinion column.The expressions expressed here are the sole responsibility of the person who signs it and do not necessarily reflect the editorial position of El Financiero.The most important news in Finance, Economy, Business and Politics of Mexico© Copyright, Grupo Multimedia Lauman, SAPI de CV© Copyright, Grupo Multimedia Lauman, SAPI de CV
