Digital Video Processor Crestron C2N-DVP4DI
reassembles the original progressive frames from the partial interlaced frames
without resolution loss and motion artifacts.
HDTV (High Definition Television)
High-definition television is a high-resolution digital television broadcast and
playback system composed of roughly a million or more pixels (picture elements),
16:9 aspect-ratio screens, and AC3 (Dolby Digital six-channel digital audio
standard). A subset of digital television, HDTV formats include 1080i and 720p
resolution.
1080i - A designated format of high-definition television in the Advanced Television
Systems Committee Digital TV standard, with 1,080 vertical pixels by 1,920
horizontal pixels. The i stands for interlaced, painting odd-numbered scan lines in
succession, then going back and filling in the remaining even-numbered lines. A
complete picture is created 30 times per second. 1080i is a high-resolution digital
television broadcast and playback system composed of roughly a million or more
pixels (picture elements), 16:9 aspect-ratio screens, and AC3 (the Dolby Digital six-
channel digital audio standard). The signal is supplied in Component format; Y
(luminance) and separate chrominance signals P
b
, and P
r
. To use a 1080i resolution
with the CNX-DVP4 or the C2N-DVP4DI it must be first converted to RGB.
Crestron recommends a converter made by Key Digital Systems, model number KD-
CTCAL (www.keydigital.com) for this application.
1080i is designated by the Society of Motion Picture and Television Engineers
(SMPTE) as 274m, 59.94 Hz (60 Hz) vertical and 33.716 kHz horizontal (33.75
kHz), 0.600 volts peak-to-peak.
720p – A format designated as high-definition television in the Advanced Television
Systems Committee Digital TV standard. This technology comprises 720 vertical
pixels and 1,280 horizontal pixels. The p stands for progressive, also called
sequential scanning, by which all odd and even scanning lines are "painted" by an
electron beam every 1/60 of a second. ). To use a 720p resolution with the CNX-
DVP4 or the C2N-DVP4DI it must be first converted to RGB. Crestron recommends
a converter made by Key Digital Systems, model number KD-CTCAL
(www.keydigital.com) for this application.
720p is designated by the Society of Motion Picture and Television Engineers
(SMPTE) as 296m, 59.94 Hz (60 Hz) vertical and 33.716 kHz horizontal (33.75
kHz), 0.600 volts peak-to-peak.
SDTV (Standard Definition Television)
Digital television format that includes 480-line resolution in both interlaced (480i)
and progressively scanned (480p) formats, and offers discernible improvement over
conventional analog NTSC picture resolution, with less noise. SDTV is similar to
DVD or satellite TV quality but not considered high-definition television (HDTV).
SDTV can provide both widescreen (16:9) and traditional (4:3) aspect ratio formats.
Most devices only output 4:3 and support the other aspect ration in a letterbox
format. See the section on Aspect ratio (next page) for more information.
480p - A form of standard-definition digital television comparable to VGA computer
displays but not considered high-definition television (HDTV), though 480p is
discernibly cleaner and slightly sharper than analog television. 480p has a resolution
of 720 x 480 and is a 4:3 aspect ratio. The signal is supplied in Component format; Y
(luminance) and separate chrominance signals P
b
, and P
r
. To use a 480p resolution
with the CNX-DVP4 or the C2N-DVP4DI it must be first converted to RGB.
Crestron recommends a converter made by Key Digital Systems, model number KD-
CTCAL (www.keydigital.com) for this application. The native resolution of DVD is
480i, but that resolution can be seen only if a DVD player outputs a progressive scan
