Difference between Audio and Component Video Cables

Even there is High Definition Multimedia Interface (HDMI) and cables, the quality analog audio and component video interconnects are still a need. Although component video is found to be decreasing frequency on the modern components, it is really capable of delivering the high-definition video. While the Analog audio jacks are just found on nearly in every home theater device. On the outside, the analog audio and component video cables are looks just similar to each other, indeed they are two different functions.

Analog Audio Cables
Analog audio (stereo patch) with cables come in a various colors, it appearance with RCA connectors and jacket. Analog audio is remaining the preference for lots of audiophiles running dedicated stereo systems. It is necessary for hooking up the subwoofers and the external amplification. As analog audio cables revolve around cable construction largely, the price is wide ranged with the environment in which that it is sold. Since the analog cables can be “tuned” to elicit a certain type of sound via differing construction methods by manufacturers, it needs to select audio components to find the right sound for your ears with care and experimentation.

With Analog cables, you can enjoy the two-channel stereo audio performance. The only drawback is that Analog cables can’t carry digital surround formats like DTS and Dolby Digital. However, it is perfectly acceptable for stereo music and sources which aren’t surround-encoded. In Additional, analog cables may pick up interference and noise over long runs, which can cause undesirable effects like a hum. Therefore, Analog audio outside of two-channel stereo system should be only using optical, for HDMI digital and the coaxial aren’t available on device.

Component Video Cables
Component video Cable is just identified by the color coding of trademark red, blue and green. Its cable jacket may color a colored band around the shell of its connector. Every cable within the trio is 75 Ohms to prevent the hindrance of the signal when it leaves the video device and travels to the television or home theater receiver. For longer component video runs, three equal with separate lengths of RG-6 coaxial cables are possibly in using. The Component video is just remaining the most commonly found alternative to HDMI with video devices.

In fact, it is important to address the composite if you want to understand component video. Composite video places brightness, color saturation and video timing signal all circuitry on one cable. While used independently, the composite video is capable of low resolution and is often filled with video noise. The three interconnects which used in the component video configurations are three composite cables. Among the three cables, one carries timing signals with green color primary and brightness cues, while the other two carry blue color intensity signals. Therefore, three equal composite video cables can be used as a component video cable. If separate these luminance and chrominance tasks separately, the resolution and color accuracy can be increases vastly to allow the component video used in high definition video applications which can’t be handled in a single composite video system.
