HDM Signal

Usually they send a simple composite video - multirumnaibolee noise-free, but less quality compared to other types (S-Video, component, HDM1). Broadcast over long distances better component analog or digital video signal is practiced infrequently. Using the hdmi interface is complicated by the it is very difficult and expensive to make long enough HDMI-cable without irreversible loss in image quality. To date, the price of such a connector can easily reach several tens of thousands of rubles, and safeguards - no However, developers are gradually overcoming these problems by increasing the length of HDMI-conductors, have been submitted workable model HDMI-cable lengths up to 20 m. We can solve the problem by installing a special amplifier video signal, increasing signal to noise ratio and thus immunity povyshayuschihtem line. True, these measures are relevant only when the funds require high picture quality. In most cases, to play, say, television in the kitchen is enough and "composite".

Managing in the second zone can be implemented in several ways. The most simple - lack of control, that is all adjustments and settings are carried out in the zone of a remote control. But such a decision, in essence, negates the very idea of "vtorozonnosti. A more advanced version - the use of external ir receiver and ir repeaters (Small sensors infrared signal that can be installed in another room and connect to the device in the main zone). Then run, say, DVD-player or receiver can be directly in the second zone, with its regular console, Y most of the current models of receivers serve as the central switching unit AV-system, there are special connectors for infrared repeaters.
