Broadcast Pix V6.2
1.2.5 Optional HD I/O
The High Definition I/O connectors on the Slate board set are BNC connectors. All
inputs and outputs can either be HD-SDI or SD-SDI for standard definition. The
bottom connector is a HD output and the remaining 4 connections are HD inputs. The
Slate system supports high definition video in:
1080i/60/59.94, 720p/60/59.94, 1080i/50, 720p/50, 487i/59.94 and 576i/50 modes
and processes HD video at 480p/59.94(NTSC) or 576p/50(PAL). It uses a process
called EDTV, Enhanced Definition Television, which has twice the data rate of
traditional SDI switchers and supports the standards:
SMPTE 296M, SMPTE 274M, ITU-R BT601-5, SMPTE 259M and SMPTE 292M.
The Slate HD boards down-convert the signal coming in and then up converts the
signal going out. The system can also down-convert going out for standard definition
on any of the other Slate outputs while outputting a HD signal on the HD output card.
1.2.6 Optional DVI-I I/O
The Slate video switcher is primarily used for broadcast television applications,
although the system can be used in virtually any production scenario. As an option
each Slate switcher can support up to two DVI-I computer inputs and up to two DVI-I
outputs (VGA adaptors are included to convert the signal as well). This is ideal for
corporate, faith or event productions where a computer source is needed, for example
to run a PowerPoint slideshow. Although it is possible to use a S-Video input or a scan
converter to bring in computer signals with a standard configuration, the DVI-I option
gives the highest quality computer signal. DVI-I Digital can support VGA to UXGA
resolutions with pixel clocks up to 165 MHz and DVI-I Analog can support RGB or
YPrPb which supports HDTV modes up to 1080p and graphic resolutions to UXGA
(1600x1200 at 60 Hz).
The DVI-I option is included with the HD I/O card and uses one input and one output
from the HD card. If two DVI-I ports are needed, then two HD I/O cards are necessary.
