Signal Type Comparisons Signal Name Description Connection Type (s) Notes RF Carries both Video and Audio modulated together to form a transmittable signal down a single cable RF Connector and Aerial leads (RF Leads) Re-modulating RF from a VCR to a TV for example adds the stereo soundtrack together to produce Mono sound. Picture quality also deteriorates when re-modulating a signal. Composite Video Carries Video Only.
Understanding Connections Technology in the audio visual market has moved at an amazing pace over the past few years with big advancements in all areas. The result of this is that even the most modest home audio visual can have upwards of 10 cables connecting devices, something that at first glance looks extremely daunting. However, there is absolutely nothing complicated about setting up an audio visual configuration providing you think about it logically and follow a few simple rules.
Understanding Connections Continued from page one… The road map thinking also works well on more complicated configurations as is demonstrated in these diagrams AV1 TV AV1 Scart Lead Video AV2 Sc art AV2 Le ad AV1 DVD On the above diagram the video signal still needs to follow the same route as nothing has changed there.
Understanding Connections Continued from page two… The previous two connection diagrams have involved direct routes from start point to destination. The next diagram shows a slightly more complicated configuration which involves going via another location before reaching the final destination. AV1 TV AV1 Scart Lead Video AV2 AV2 Scart Lead AV1 Sky Box On this configuration we want the signal to come from the sky box end up at the television AV1 socket.
Understanding Connections Continued from page three… The other common type of connection which most people are familiar with is the ‘RF cable’ or ‘Antenna’ cable. This is the type of cable which has been used for years to carry signals from your house’s roof antenna to videos and televisions in your front room. Most audio visual configurations will also need an antenna or ‘RF cable’ to refer to the official term to run right through their setup in order to carry the signal around the different units.
Understanding Connections The newest connection type is the HDMI or High Definition Media Interface. This carries high definition Digital Audio and Video signals from an HD source such as a BluRay player to the TV. It also carries sophisticated but simple to use switching and control signals such as Viera Link HDMI Lead HDMI HDMI 1 TV BluRay Player HDMI 2 HDM I Lea d HDMI Sky HD Unlike the Scart lead the HDMI carries the Digital Audio and Video Signals in one direction only.
