Explorer® 3250HD™
High-Definition Interactive Set-Top
Description
Scientific-Atlanta’s Explorer® 3250HD™ High-Definition
Interactive Set-Top merges high-definition video capability
and broadband digital video services to deliver a broad
range of entertainment, information, and communications
services.
The 3250HD decodes all 18 ATSC digital video formats,
including the 6 high-definition (HD) digital formats for
HDTV. All standard-definition digital formats and all analog video services
are decoded as well. This comprehensive level of decoding capability
in one set-top box enables cable service providers to quickly scale
HDTV video services for both analog and digital consumers.
The 3250HD can output video to the HDTV display in four resolutions:
480i, 480p, 720p, or 1080i. These resolutions, or scan rates, allow consumers
to select the scan rate best suited for their HDTV set. Consumers can
stretch and zoom the video picture to maximize its viewable area on the HDTV display.
For added connectivity, the 3250HD offers optional loop-through that provides
a set of component HDTV inputs, a composite video input, and both analog audio
and optical digital audio inputs. A consumer with limited inputs on their HDTV
can use the loop-through connectivity feature on the 3250HD to connect additional
electronic devices.
