When a tired executive comes home late from work, oftentimes their first priority is to relax on the couch in front of their HDTV and home theater system, while enjoying entertainment in High Definition. But the scenic view is scathed and the savoring left incomplete by of the trail of wires emerging from all the different devices. The only solution to such a predicament is to switch from having a wired entertainment system to a wireless one.
HDMI is High Definition Multimedia Interface. It serves as an interface for HD (High Definition) devices such as HDTVs, DVD players, home theater systems and even gaming consoles. One of the greater benefits of HDMI was that it used a much advanced cable, able to convey a bandwidth of 5 Gbps, which significantly cut down on the amount of wires tangled behind the television set. HDMI is bound to gain further ground in popularity because of the fact that it is now available in wireless mode.
The main reason why HDMI is so popular is because it provides greater quality to the viewers. This is because the signals used in the HDMI system are completely digital, whereas previous systems were analogue. This means previous systems repeatedly converted the signals from one form to another. By the time it was finally converted to digital in the television set, it will have lost a lot of its quality. However, during HDMI, the system preserves the complete quality of the signal and provides the clearest and sharpest display.
The core device that will enable HDMI to go wireless is the HDMI transmitter. This is a laptop-sized black box which has the capability of receiving data from devices such as the DVD player, compressing and encoding the information, and transmitting it to the TV and the home theater system where they will then be decompressed and enter the system through the HDMI port. All the processes will happen simply by using radio emitters to carry the data rather than employing wires. Similar to all forms of technology, the transmitter is large only because the technology is new. It is likely to become smaller as the science behind it progresses. Simply recall the size of the first cell phone and what they have become now!
Wireless HDMI technology can currently process and transmit data at a rate of 3Gbps, and the rate is only set to increase further in the future. The compression system used to compress the data is based on JPEG algorithms, which the reader may be familiar with as it is the technology employed in compressing photos such as family photos stored inside a computer. The signals used to convey the data are so strong that they don’t even need to have complete visibility. They can be placed in different locations, such as another room or floor, as long as they are within a certain range. Now, wireless HDMI transmitters are able to transmit data to devices which are within a range of 15 feet. The range of the transmitter can be helped further by using a range extender, through which the range can then be increased to distances up to 100 feet.
Usually, entertainment devices such as TVs and home theater systems are selected and placed by the husband, while the wife remains uninterested. This is mainly because of the fact that they do not like the amount of wires used by these devices spoiling the view of their living room. However, now that HDMI has turned wireless, more wives are becoming interested in choosing their HDTV and selecting a location for it in their house. This was one of the intentions of HDMI, to make more people interested in making their viewing experience more pleasurable.
