Leitch X75HD, Руководство по эксплуатации продукта

Страница: 49 / 62

What technique is used for the (optional) analog to digital video conversion?
There are two options available: X75OPT-A3D industry leading fully adaptive 3D comb filtering,
X75OPT-PQM 2-D 3 line adaptive combing with 3D cross color artifact removal filter. Both have 12-
bit resolution with optional SDTV noise reduction.

When will the free software for the logo generators be available?
Mid-September 2005
Does the X75HD provide frame rate conversion (59.95 <> 50)?
Frame rate conversion (59.94<>50) for HDTV is not available at this time. However, 3:2 / 2:2 and
reverse 2:3 conversions are available (23.98p<>59.94i and 25p<>50i).
Does the X75SD provide standards conversion (525 <> 625)?
Standards conversion for SDTV (525<>625) is not available.
Does the X75 accommodate a HDTV analog component interface?
No, not at this time. However, we are willing to discuss this capability.
Does the X75 accommodate a HDV interface?
No, not at this time. However, this is on the roadmap for the future.
Does the X75 accommodate a HDMI interface?
No. HDMI is an encrypted signal that carries HDTV video signals from a set top box (cable television
or satellite direct-to home services) to a HDTV display/monitor. This format is used in the home
environment.
Does the X75 accommodate a Firewire (IEEE 1394) interface?
Yes. The IEEE 1394 interface is used for DV 25Mb/s SDTV.
Any plans for USB-2?
No, not at this time.
Does the X75SD version have SDTV ARC (Aspect Ratio Conversion)?
No. The HDTV option is required for SDTV Aspect Ratio Conversion
Does the X75 provide clipping?
Yes. There are Black Clip Enable, Black Clip Level, White Clip Enable and White Clip Level controls
for each of the Analog, SD1, SD2 and HD inputs.
Does the X75 do proper color space conversions?
Yes, proper color space conversions are done when converting to/from analog and digital SDTV
signals and when converting to/from HDTV signals.
Can the SDI and composite outputs be separately phased? Is it infinite phase?
The analog FS will phase both analog and SDI outputs. However, the utility delay line can be used to
apply the additional delay when added to the path. This applies to having only one input signal.
Can the SDI output be delayed by 1-2 lines from the composite output?
This can be achieved by the following configuration: SD1 ==> SD1 FS ==> analog output / SD2 ==>
SD2 FS ==> SDI output (
Note : Feed the same SDI signal to SD1 & SD2 inputs and then adjust the
timing from both FSs.)
