LV 7380
MULTI SDI RASTERIZER
GENERAL
The LV 7380 is a 1U, full rack rasterizer that displays video
signal waveforms, vectors, and pictures of HD-SDI and SDSDI signals on an external LCD monitor. The LV 7380 also
has a variety of other features. It has audio signal display
features that include the Lissajous and level meter displays of
embedded audio. It can display two SDI signals at the same
time. It can save screen captures to USB memory. It can
also display gamut errors over the picture. SDI signals that
are received through channel A and B can be reclocked and
transmitted from the OUTPUT A/B and OUTPUT B connectors
with a press of one of the INPUT keys.
With a factory option, it can also display eye patterns of SDI
signals. All these features are packed in a small unit that is only
250 mm deep.
FEATURES
Two Serial Digital Inputs and Outputs
■
The LV 7380 is equipped with two SDI inputs. This enables
the LV 7380 to receive two different SDI signals and to receive a single signal in dual link mode. The LV 7380 can also
generate a serial reclocked SDI signal for each SDI signal
that it receives.
SDI signals that are received through channel A and B can be
reclocked and transmitted from the OUTPUT A/B and OUTPUT B connectors with a press of one of the INPUT keys.
DVI-I Output
■
The screen image is displayed in XGA resolution (the effective resolution is 1024×768). The supported DVI-I output
signals are single-link TMDS and analog RGB.
Multi-Screen Display and 2-Channel Simultaneous Display
■
The LV 7380 has a multi-screen display that can display a
video signal waveform and a picture at the same time and a
multi-screen display that can display vectors and an audio level meter in addition to the waveform and picture. It also has a
multi-screen display that can display two SDI signals simultaneously. Different measurement modes can be assigned to the
four different areas of the multi-screen display. (This feature is
not available for the 2-channel simultaneous display.)
CINELITE II (CINELITE feature and Leader's patented CI-
■
NEZONE feature)*1
The LV 7380 comes standard-equipped with CINELITE II
(CINELITE and CINEZONE), which is a video signal luminance information analysis tool.
Picture Display
■
The LV 7380 uses fully digital waveform display processing to achieve high precision and versatility. The display
has a number of adjustment features such as brightness
adjustment, contrast adjustment, gain adjustment, bias adjustment, and aperture adjustment. It also has monochrome,
chroma up, gamut error, and safety marker display features.
The LV 7380 is also standard-equipped with CINELITE II, a
convenient tool for adjusting the lighting during lming.
Waveform Display
■
The video signal waveform display has gain, sweep, and
cursor measurement features, along with RGB and pseudocomposite display features. In addition to video signal
waveforms, the LV 7380 can also display vectors and display the Lissajous curves of embedded audio.
5 Bar Display
■
The 5 bar display enables the simultaneous monitoring of
component and composite gamut.
Status Display
■
The status display can display the SDI signal's error count
and error log, a data dump, and the phase difference between an external sync signal (a tri-level sync signal or an
NTSC or PAL black burst signal) and the SDI signal.
Time Code Display
■
LTC or VITC time codes can be displayed.
Screen Capture
■
The display can be captured and stored as image data. Not
only can captured data be displayed by the LV 7380, but it
can also be compared with an input signal or saved to USB
memory as bitmap data. The saved bitmap data can then be
viewed on a PC.
Error Detection
■
SDI signal errors, such as HD-SDI signal CRC errors and
SD-SDI signal EDH errors, and various errors related to embedded audio signals and ancillary data can be detected.
ANC Data Analysis
■
Various ancillary data can be analyzed, and the results can
be displayed.
ID Display
■
IDs can be assigned to input channels. IDs are entered from
the LV 7380 panel.
Equivalent Cable Length Measurement Feature
■
The LV 7380 converts the SDI signal attenuation to a cable
length and displays the result.
Closed Caption Data Display
■
The LV 7380 can display the closed caption data embedded
in an SDI signal over the picture display. It can analyze and
display status and control information.
1) CEA/EIA-608-B closed caption data in CDP packets that
are de ned by EIA-708-B
2) CEA/EIA-608-B closed caption data
3) VBI (CEA/EIA-608-B line 21) closed caption data

When these signals are displayed, phase differences of up to 100
clocks (approx. 1.4 μs) between links A and B are automatically
corrected.
If links A and B are not synchronized, the various error detection
features that are shown on the status display do not operate
correctly.
