High Definition Multi-media Interface (HDMI) is a method sending a digital video signal from a connecting device to your television. Normally to send these signals the original connecting device is required to make a conversion of digital-to-analog for the process to work properly. This conversion will cause some data loss but can be avoided with the use of a HDMI connector. A HDMI connector avoids the need for the conversion process, which will ultimately prevent any information from being lost in the process.
Digital video signals can be sent from the connecting device to your television with a HDMI connector without any conversion being done. Simply put, a digital signal can be sent. There is no need for it to be converted to analog. The ultimate result of this, as already mentioned, is a complete transfer of all the available video data. As well, keep in mind that a HDMI connector transfers both video and audio data to your television.
What Exactly is HDMI?
While we already have a general idea of what HDMI is used for, we also need to look at what HDMI really is. HDMI is a multi-media interface that is used to legally send audio and video information that is both uncompressed and encrypted. This information is sent in the form of a digital stream and is available in real-time.
Many popular consumer electronics brands offer HDMI connectors, such as Philips, Hitachi, Toshiba, and Sony. Almost any company that makes televisions or other major electronics that can use HDMI connectors will likely produce the connectors as well.
The Physical Characteristics
A single HDMI connector simply consists of just one cable (15mm) which features a 9pin design. This cable will transfer the audio and video signals from the connecting device to your television. You can also conveniently use a universal remote control so everything within your home theatre is controlled with the same device.
HDMI vs. DVI
There are similarities between HDMI and DVI as they are designed to perform the same task. However, they are not necessarily on the same performance level. HDMI is simply better than DVI in every aspect and a HDMI connector is simply an improved connector in comparison to the DVI connector.
HDMI has become a popular replacement for DVI and is at a pinnacle in popularity amongst consumer electronics companies. Overall there is not much to debate about the two when comparing them, as HDMI is the media connector of the present, and future, while DVI is quickly becoming a thing of the past.
History Behind HDMI
Early releases of HDMI connectors occurred in 2002. A variety of popular consumer electronics manufacturers produced these cables. Over time there have been many enhancements and additional features have been included with updated versions of the cable. For instance, while all HDMI connectors are compatible with a video resolution of 1080pi, the audio performance will vary by HDMI connector specifics.
An older version (Version 1.0) of HDMI connectors was capable of decoding the majority of audio on both DVD’s and digital TV signals. However, the best results come from the most recent version of HDMI connector (Version 1.3). This particular cable is compatible with Blu-Ray DVD’s and High Definition DVD Players alike. The bandwidth for this particular cable is also improved, sitting at 10.2Gbps. The major benefit of a higher bandwidth is that it makes for transferring high definition signals much better.
HDMI Connectors Today
As mentioned in the previous section, Version 1.3 HDMI connectors are the most recent option we have. The performance of these is acceptable even during the more advance tasks with high definition signals being transferred. The technology is continuously advancing though and there will be more updates to HDMI connectors in the future.
There are already a lot of advancements to the characteristics of HDMI connectors that make them ideal to use though. If you are considering switching from DVI to HDMI then you will not regret making the move. While the difference may not be noticeable for some people, the quality and performance is improved dramatically when dealing with heavy duty transferring tasks.
