VIDEO SYSTEM SHOWING ORIGINAL CHANNEL DURING ZAPPING ON A TV

摘要

The invention relates to a video system which is able to show more than one channel at the same time. If a user, after watching an original channel sufficiently long, zaps to another channel, the original channel is displayed in for example a PIP, together with the new channel in a main picture. After zapping yet to a third channel, the original channel is still displayed in the PIP. In this way, the user can keep track of the original channel while zapping other channels.
