The Portal accesses content from the Arris Gateway TV box system or Gateway HDPVR. With the Arris Gateway TV box (shown above), a Portal is required for each TV in the home that you want to access the system on. The Gateway HDPVR may be used as a 500 g hd standalone unit for a single TV, or you can add up to five more Portals to access the system on multiple TVs. With the Portal connected to your TV, you can view HD channels and full HD-quality, 1080p Video On Demand content made available to you through your Shaw Gateway system. In addition to this, you can record up to six programs simultaneously, while playing back a previously recorded program, and viewing 3D* content in MPEG4 format at up to 1080p resolution.
