Background to the Worldwide VCR

GB
Today the Video Recorder is a major media and communication tool, used for both business and home
entertainment. Furthermore, the emergence of the camcorder has extended the versatility of the video
with home video making.
Video communication is increasingly becoming a global medium, but the different TV broadcasting
systems around the world hinder the worldwide exchange of video tapes.
The Samsung SV-7000W overcomes the incompatibility of different TV broadcasting systems through
sophisticated digital technology, allowing any standard VHS tapes to be played on any TV, any where in
the world (with free voltage).

Worldwide TV Color System

Many countries have different TV signal formats, with no exchangeability between them. This makes it
impossible to play back or record tapes with different signal formats. This worldwide common VCR
overcomes this problem by converting the signal format of any tape into the format you desire.
