Data transmission for computer connectivity to the internet is best achieved using a Cat5e cable system back to a central router/hub. This enables all computers to share internet access for web, email and outside communications.

Telephone systems should also be connected using another Cat5e cable network which ensures systems are again routed back to a central point and then to the outside world.

Audio distribution from a central CD server to each room using digital cable running line level signals to local amplifier speakers will enable any one of 4 million channels to be selected: classical music for the parents, heavy rock to Kevin the Teenager and Steps to the Little Princess with good old Terry Wogan to the kitchen. Additionally it may be preferable to run the amplification centrally using a zone amplifier: this can then send the audio direct to the speakers at the desired destination.

Should you wish to distribute computer video signals this can be done using VGA cable which is bulky and expensive. However, connectivity may be better achieved using a Cat5e network which enables data and audio to be encoded and sent down a much thinner and cheaper cable to each destination point.

Fibre optics may be used but have serious cost implications and physically for multiple channels the cables have minimum bend radii which often are difficult to achieve in a domestic environment. The advantage is that future connectivity is assured, but will require third party trained personnel for set-up and maintenance thus adding to potential costs.
