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, and many computer 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 and consumer electronic control signal. 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 the TV via HDMI and use a separate connection, 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 dedicated 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 'more about this, but keep away from more expensive brands, because they provide little additional benefit.
