The video and picture viewing expertise has improved over time. Since the start, analog signals have been the principle technology. Through the years, it evolved to both analog & digital signals together. Now the technology has finally paved its way into the zone of digital signals.
Not just the technology but also the cables which carry these signals, evolved over the time. From the monitor of a computer to a Television set or, even a home theatre system; they all feature different sets of connecting ports. These ports allow the usage of different types of cables and support different set of signals. Driving force behind this change is the growth in scientific developments.
It was the question of survival for many companies. They had to provide the users something new for staying in the aggressive market. The companies finally could take a step forward after investing ample amount of hard work. So did the buyers. The 21st century is arguably the spark plug of the digital age. The video viewing technology is the driving forces behind this.
Before this high definition age, there were many video connections available for TV, VCR, DVD, and HDTV & Monitors. They all operated on analog signals. The most commonly used monitor cable was the Video Graphics Array (VGA) cable. Further developments popularized the Digital Video Interface (DVI). It operated on both analog and digital signals. They all had certain limitations and the latest High Definition Video Interface overcame them all.
Let us check out this new technology.
HDMI (High Definition Multimedia Interface)
HDMI brought the dawn of this new digital age. It is a technology, which came into the market within the first two years of this millennium. HDMI Cables operate this technology, which combines digital video signals and multi channel audio signals into one convenient cable.
How does this differ from earlier cables?
Well for a start, this can eliminate the maze of wires that use to assemble around your earlier setup! It aids in convenient management of cables as it reduces the complexities and cost.
Quality with More Flexibility
With earlier technology of Digital Video Interface (DVI), you had to plug-in the audio cable separately. As it could carry, only the digital video signals, it created this limitation. If its length was more than 16 feet, it compromised with the quality. The usage of HDMI eliminates this hassle. It can be as long as up to 40 feet while still maintaining the optimum quality.
In addition, you do not need to worry if you are looking for an upgrade! HDMI cables are also compatible with the DVI. Hence, it eliminates the need to upgrade immediately your existing cables and components.
Higher Resolution and Remote Control
HDMI is the first and foremost interface to carry high definition video of the likes of 720 & 1080 resolution. It also brings in the multi channeled surround sound signals.
Another key feature of HDMI Cables is that it provides the ability to control the entire system of components and display unit using a single remote control.
Higher Transfer Rate
Above all, HDMI Cable is capable of sending uncompressed digital video and audio signals at a very high transfer rate up to 5 gigabytes per second. In simpler terms, it has the ability to send large amount of data across a long stretch of wire and that too at a very high speed.
As you would know that the high resolution and high definition videos sample at very high rate, the output is sharper and clearer than the analog signal interfaces and the conversion from analog to digital signals can have room.
