To complement its audio performance, the SDP-40HD features two
broadcast-quality video switchers. An ultra-wide bandwidth
component video switcher accepts analog component or RGB video
signals, & can pass analog high-definition (HD), enhanced-definition
(ED), and standard-definition (SD) TV signals. A composite and
S-video switcher accepts NTSC, PAL or SECAM video signals. Both
switchers are designed to pass video signals without alteration or
degradation. In addition, the SDP-40HD can convert composite and
S-video input signals to analog component video.
High-definition digital TV (HDTV) broadcasts require equipment
that can process and display digital video signals at a resolution of
either 720p or 1080i. For sources with HDMI digital video outputs,
the SDP-40HD delivers these resolutions through the HDMI output
to compatible display devices.
Analog 720p or 1080i video signals can pass through the
broadcast-quality component video switcher. In comparison, most
standard-definition (SDTV) broadcasts have a resolution of 480i.
Some DVD players and enhanced-definition (ED) digital TV
broadcasts have a 480p resolution. For digital video input sources
using an HDMI interface, the SDP-40HD delivers these resolutions
through the HDMI switcher.
Resolution is defined by the number of horizontal lines displayed
on-screen that comprise each frame of a video image. The more
lines of resolution used to create each frame of video, the greater
the detail and sharpness of the image. For example, the resolution
known as 720p refers to 720 horizontal lines of progressive video.
The resolution known as 1080i refers to 1,080 lines of interlaced
video.
An unparalleled processor, the SDP-40HD conveys the best in music
and cinema with awesome power and leading-edge technological
sophistication. Even the most demanding enthusiasts will be
impressed with its exceptional performance. The SDP-40HD is a
must-have addition for any high-quality home theater.
