Before the arrival of HDMI connectors, video and audio sources that handled digital information, like DVD players, and video game consoles, had to use a connector that would transform that information from digital to analog in order to send it to an analog receiver, such as a standard TV:
However, with the arrival of HDMI technology, this changed. An HDMI connector can transfer digital data as it is from a source to a receiver. It also features greater bandwidth than previous formats. This results in a better transfer of information and a much better quality of video and audio, since information travels faster, cleaner, and in bigger quantities.
Of course, an HDMI connector will not work on a normal TV, as they require analog information. A high definition TV that supports HDMI is needed to enjoy the benefits of using an HDMI connector.
In addition, both the source and the receiver have to match one of the 3 HDMI connectors there are.
The first type of HDMI connector is called type A. This connector has 19 pins and measures 13.9 by 4.45 millimeters. It supports Standard Definition Television (SDTV) resolution, Enhanced Definition Television (EDTV) resolution, and High Definition Television (HDTV) resolution.
The second type of HDMI connector is called type B. This connector has 29 pins and measures 21.2 by 4.45 millimeters. It features double the bandwidth of the HDMI connector type A. It supports the same resolutions as the type A connector, as well as Very High Television resolutions such as Wide Quad Ultra Extended Graphics Array (WQUXGA9).
The third type of HDMI connector is called type C. This connector has 19 pins and is very similar in capabilities to the connector type A, except that is smaller and designated for portable types of equipment. It measures 10.42 by 2.42 millimeters.
Most people have only one receiver, but several sources. Some common HDMI common sources are DVD players, video game consoles, Blu-ray players, and cable boxes.
If that’s your case, you might consider getting an HDMI switch box. This device till let you connect all your sources devices to a single device. One HDMI cable then goes from the switch box to your plasma TV or any other receiver.
Then, it’s just a matter of pressing a button on the HDMI switch box to select which signal you want to be sent to the receiver. Some HDMI switches also work by remote control, which is nice since you don’t even have to stand up.
Finally, if you haven’t jumped on the bandwagon of the HDMI technology, I suggest you do it soon. I believe that HDMI will be the standard of the industry.
