The Explorer

3240HD™Digital-Only Set-Top provides subscribers with improved video/audio quality and the
flexibility to support interactive applications and services.
The 3240HD offers cable service providers the ability to create a digital content delivery system for the cable
subscriber. The transition to a digital system will free bandwidth for additional services.
Features
The 3240HD is a digital-only set-top that will
tune standard-definition (SD) and
high-definition (HD) digital signals available
on the cable system to which it is
connected. The digital tuning capability
provides a clearer noise-free picture to the
subscriber’s display device. Because this is
a digital-only set-top, it is unable to display
analog services.
The 3240HD decodes all 18 ATSC digital video formats, including the 6 HD digital formats for HDTV. All
standard-definition digital formats are decoded as well. This comprehensive level of decoding capability in
one set-top enables cable service providers to quickly scale HDTV video services for digital subscribers.
The 3240HD can output video to the HDTV display in four resolutions: 480i, 480p, 720p, or 1080i. These
resolutions, or scan rates, allow subscribers to select the scan rate best suited for their HDTV. Subscribers
can stretch and zoom the video picture to maximize its viewable area on the HDTV display.
To meet the demands of existing and future network configurations, the 3240HD offers power, capacity, and
compatibility. The integrated internal DAVIC cable modem allows the 3240HD to communicate instantly with
the cable headend to promote a broad range of interactive entertainment, information, and communication
services. Over 40 MB of application and program memory, along with the 166 MHz RISC microprocessor,
manage multiple program tasks and applications with speed and power.
Taping an HD broadcast to an analog VCR is seamless with the 3240HD. The set-top simultaneously displays
the HD image and downconverts it to an SD image through the NTSC outputs. In order to make recording
digital services easier, the optional VCR Commander™ Service integrates the interactive TV program guide
with the VCR so that subscribers simply point-and-click to setup and record programs.
