HDMI - A new standard for connecting home cinema

HDMI is the new type of connection to all new modern television, the most advanced home theater amplifier, several computers and monitors. But why is it important to buy a device with HDMI connection, and how much you should spend on HDMI cables?

HDMI stands for High Definition Multimedia Interface, and is designed to provide a backwards-compatible replacement for the DVI interface commonly found on computer monitors. The standard for a single cable that transfers could beHigh-definition video stream, up to eight channels of digital audio signal and a Consumer Electronics Control. Its main purpose was to determine the standard connection between all consumer AV devices, and computer monitors are. Today, all new television sets and projectors are equipped with at least one HDMI connection and usually get more high-definition video.

Perhaps the most important part of the HDMI specification has support for HDCP, High-bandwidth Digital Copy Protection.HDCP-protected content such as Blu-Ray can be decoded only with HDCP licensed player, and all devices that connect to the player, must be HDCP certified, or the player only output a signal to standard definition. For this reason, the purchase of high-definition projectors, TV or other devices, you better make sure they have HDMI ports and HDCP are unaudited.

Be careful when you connect your home theater system. You can not have an HDMI connection toAmplifier, and then a connection to the projector component, such as HDCP, the player to send a hi-def video signal through the last link can not be prevented via HDMI. However, you can get your Blu-ray player or cable box to connect to a TV and a HDMI connection part, how to send a digital optical audio cable to your amp.

HDMI transmits both audio and video. This means that one cable is needed to connect a TV to the Blu-rayor cable. If you have a separate home theater amplifier to be used, then the player and cable box can be the first to the amplifier, which are then connected to another HDMI cable connected to your TV. In this configuration, the amplifier of audio channels and passes the video channel on your TV. If you use the approach for a high quality home theater amplifiers are looking for, with multiple HDMI inputs for all sources that support HDCP.

Finally, a word to buy an HDMI cable. The prices of HDMICable can be very different, with some brands of cabling costs 10 times the price of the length of the cable without marking. In practice, the quality HDMI cables very little impact on the quality of audio and video are transmitted through them. Unlike the previous home-video cable, HDMI is a digital connection, so that the signals are much more resistant to interference and noise. For short cable lengths, most HDMI cables will be fine. Longer lengths may be more prone to connection dropoutsignal loss due to the HDCP, so consider spending a little extra on it, but keep away from more expensive brands, because they provide little additional benefit.

Because HDMI is the first choice for all home cinema connections

The introduction of high-definition TV has really improved the home theater experience enjoyed by consumers, but also caused much confusion and uncertainty. It does not help that the producers have focused their efforts on different types of connections over the past ten years, now there are thousands of different devices on the market, which means that all the different types of plugs. Firewire, DVI and HDMI are all kinds of connections that have enjoyedHave been found and the spotlight on the shoulders of the TV at one time or another, and now most consumers are totally confused about the differences between these compounds and what type is best.

What is the problem on the links?

Many people do not understand why there is a big problem for something as simple as a name, but it's just a way to connect the cable to the TV, all the connections certainly do basically the same thing? The war between different types of connectionsreal money. It costs a fortune for the company to develop a new content platform, so I'm very busy, many producers that their connection as possible so that they will receive a royalty payment. If a connection is created as a global standard, then it may be mentioned incredibly profitable for the company that owns the copyright to the competition and try so hard to establish a link on connecting global standard for all HDDevices.

The emergence of HDMI

As the technology behind HDTV has been developed quickly realized that a new connection is necessary that not only delivered quality digital signals, but also to use for consumers. The first attempt was a digital FireWire connection - using a single cable to carry audio and video signals, and communicate with other approved devices. However, FireWire has never really won much support from the manufacturer, and then fell quicklyout of fashion, without ever reaching his potential.

DVI was next and was originally developed for the PC industry. DVI cable run only video signals, but they were able to support both analog and digital connections. As a manufacturer of home entertainment, as DVI had won the favor of PC users, have begun to DVI interfaces in their products. But the thought of large form factor and lack of audio support, it is not optimally suited for use in home theaterSystems.

HDMI is nearly identical to DVI, but it provides improvements in some key areas. For example, using the HDMI cables have a connector with a much smaller form factor, which is important when space is limited behind your home entertainment system. HDMI is also capable of audio and video signals over a single cable to carry, which means that one cable is needed to establish a connection. HDMI cable, will also have a remote control command, the connection process and simplifiesUsing multiple devices together. Perhaps more importantly, the HDMI cables are relatively cheap to produce, and therefore have become very popular in high-definition TV and producers of home entertainment.

HDMI is the sensible choice

As you can see HDMI cables offer numerous advantages over other types of connections, which explains why the vast majority of home entertainment devices in recent years has produced most likely to use HDMI as a standard interface.
