Why hdmi cable

Instead of three to five things to plug in, you've only got one. That one cable carries everything you need to enjoy your favorite movies and shows. In fact, the newest specification even contains an Ethernet channel to streamline networking those Smart TVs and Internet-connected devices.

It also has an Audio Return Channel for reducing cable clutter when you've got a receiver in the mix. This means you're able to get that brilliantly vivid high definition picture at the best possible quality your hardware allows. On most devices, component connections max out at i. HDMI also has the ability to transmit uncompressed signals to achieve better resolution without any loss in quality. For capable devices, you are able to view raw, unprocessed footage. Who wouldn't want to do away with all those remotes that keep getting lost in the couch cushions?

Keep in mind, the devices connected have to be CEC enabled to make this an option. Not all devices have this feature enabled. Going Digital If you want to achieve that true theater experience in your home, more than likely you've invested in surround sound or something similar.

The newest specification also supports 3D video. Mobile Connectivity Americans are glued to their Smartphones--there's no question about that.

Now you can show those kiddo pics and videos in their full splendor to a willing or unwilling audience and stream until your heart's content. Since the transmission of the signal is based largely on the power output of the devices to which it is attached, the distance can be limited depending on the source. For example, Blu-ray players can usually successfully send an HD signal up to 50 feet away, while computers and gaming consoles max out at 30 feet.

This is just a rule of thumb, as every device varies and your mileage may vary. Component cables can be run hundreds of feet with no signal degradation, so you can see why some people might prefer to stick to their tried and true cables.

There are ways around this distance limitation, however. HDMI extenders can take the signal further, and many switches and splitters come equipped with signal-boosting technology out of the box. This means they're not compatible with newer devices that do have HDCP protection. This little means of security has been known to cause big headaches, as it can cause hiccups in connections from time to time. How do HDMI cables work? HDMI works by the use of transition-minimized differential signaling technology to transfer information or data from one location to another.

The transition-minimized differential signaling TDMS is a technique that protects information from degradation as it travels down the cable length from one device to another. What happens is that the sending device encodes the signal by reducing the number of transitions. This helps to protect the quality of the signal and limits chances of degradation.

As the information is transmitted, one of the twisted pair of cables carries the signal itself while the other carries the inverse copy of the signal that is in transmission. Upon arriving to the receiving device, the HDMI measures the difference between these signals and uses the information to compensate for the signal loss.

However, there are various versions with different scopes of features, and various cables. This will often lead to confusion — this guide unravels the tangled web of HDMI. It is an interface for electronic devices via which video and audio signals can be transmitted digitally with almost no loss of quality. External devices such as receivers, Blu-ray players, set-top boxes, media players, games consoles or notebooks are also connected to the TV via a HDMI cable.

Peripheral devices obviously also need to have a HDMI socket. Since then a lot has happened — further improved HDMI specifications have been published, offering additional features.

For the sake of clarity, we have concentrated on the relevant ones. HDMI version 1. However, HDMI version 2. HDMI 2. For the average consumer, the ability to connect their TV and DVD player with just one cable certainly makes setting up a home entertainment system less daunting. In conjunction with looking at the version number, it is also recommended that you look at the features supported by the version and ensure the feature you want is specified in every device and cable in the system.

Like all formats, cable quality does vary between brands. It is important to buy a cable that is HDMI certified to ensure quality, longevity and increase resistance of interference from other systems.
