Advantages and disadvantages of HDMI (High Definition Multimedia Interface)

The advantages of HDMI (High Definition Multimedia Interface)

1 The industrial producers, such as HDMI, because it is a system of interfaces, the media used to stop piracy. This system called HDCP (High-bandwidth Digital Content Protection). This system works on encrypted (see copyright), DVD-Video, DVD Audio, HD DVD and Blu-ray Disc

HDMI also carries audio and video in one cable, which then allow the manufacturer to have a lower number of connections and a single standard in / outInterface.

Customers like 2 HDMI, because they create less confusion in the connection. A single cable connects the DVD player to your receiver or TV. Almost all digital audio / visual, such as gaming consoles, Blu-ray DVD players, etc. This can combine uncompressed (faster) format can be used.

3 Another good basis for the HDMI CEC (Consumer Electronics Control), which control a device connected to another device connected, if necessary, is possible.This is most evident when you can use the remote to control all connected devices.

Cons: HDMI (High Definition Multimedia Interface)

1 Holders of old equipment can not have HDMI ports. Instead have separate audio and video interfaces. These customers need to do workarounds to HDMI, to adapt their systems or buying new equipment. These solutions can buy cable, an HDMI cable at one end and a DVI (Digital Video Interface) have the other endto send video to a monitor or a TV with a DVI connector. This would allow a user, a video from a DVI-HDMI source to a receptor, but does not send the audio because DVI does not support audio.

2 To send the audio to a non-HDMI audio / video component, you must send it on existing methods, such as S / PDIF (optical fibers) or RCA cable.

3 There is some confusion because of the numbers on the HDMI connections. Starting from 1.0, the ability of HDMIHDMI cables and devices. The standard to be HDMI 1.4a, Deep Color, 3D and excludes postponed. Each implementation of the standard HDMI cable has a corresponding implementation in audio / video. If you buy the cable or equipment, make sure that the equipment corresponds to the cable. Newer cables are compatible so that it is an easy choice - always at the highest level (number) go to the wire. You can not help but not hurt.

In short, control the audiovisual system and see what the connections with large parts such as television, amplifier, CD player and cable / satellite links are working. If you're buying new, make sure the new device works with the old device. Your audio / video system is like an eco-system: Change one thing and others will have to adapt. The most obvious upgrade path can be to your TV. Make sure that a new TV has HDMI ports as well as older terminals are required to workold amplifier or CD player. The Internet is a great place to quick information about what you need.

Finally, you can consult your dealer. Take a picture of the front and rear of all devices in your home theater. Make sure that the connections are free of photography. The dealer should be able to help. But attention to the price. A good HDMI cable should be no more than about $ 10 and a base 1.4 cable should be all you need, at the time of thisThe writing, including Ethernet. If the numbers of the past 1.4 GB, only the largest number, are compatible and do not cost much.

The electronics industry is now moving away from the use of numbers and advises customers on equipment they need to connect and play with the cables, check to buy it.

It 'just a sales technique that could cost a lot of dollars useless - not in the "giant" or this "future proof", which are sucked. Testers also that the connections off the groundand testing are rarely problems with the less expensive cable.
