Extra View is an economical and convenient way of watching different channels on different decoders under one DStv subscription. So, instead of having multiple DStv subscriptions for each decoder, you can link the decoders under one DStv subscription.
To put it in simple terms, let’s assume that we have family members who may want to watch different TV channels at the same time. This can cause family members to squabble over the remote control. So, extra view solves this problem by allowing each family member to watch a different channel. To add to that, you and your family can record different shows on separate decoders. When using Extra view, you can watch up to 3 live TV channels at the same time.
