The LV5770A Waveform Monitor for 3G/HD/SD SDI Signals with SDI Input Card from Leader is a multi-SDI monitor that can monitor two 3G/HD/SD-SDI sources simultaneously and displays Picture, Waveform, Vector, 5-Bar, CINELITE II, and Status individually or in various screen combinations. Loudness, lip-sync, surround monitoring audio centric features are integrated in this monitor.
The 1-screen display feature can be used to show each of the different displays on a
single screen, or the 4-screen multi display feature can be used to divide the screen into
four areas with a different display shown in each area. The video signal waveform display,
picture display, audio level meter display, and histogram display can be shown as a
thumbnail display on the 1-screen display.
A screen capture feature that captures the screen as still images, a frame capture
feature that captures single frames of SDI signals, and an error capture feature that
automatically detects and captures error frames are available.
Not only can captured data be displayed by the LV 5770A, but it can also be compared
with an input signal or saved to a USB memory device. It is easy to view the saved data
on a PC.
The LCD display is a 6.3" XGA screen (the effective resolution is 1024 × 768). In
addition, the screen images are transmitted from a DVI-D connector that supports single
link TMDS, so the screen image can be displayed larger than is possible on the LV 5770A
through the use of an external LCD.
The input SDI signal can be generated as an 8-bit signal. Regardless of the SDI input
signal, the output format can be set to YCBCR 4:2:2, YCBCR 4:4:4, or RGB 4:4:4. 3D video signals can be evaluated by applying the video signal for the left eye to channel
A and the video signal for the right eye to channel B. The available picture display
formats are anaglyph, convergence, overlay, wipe, checker, and flicker.
You can use the cursor to select any 3 points and display their luminance information
using f-Stop numbers, percentage values, or level values. You can choose to analyze a
single pixel or a small area by setting the size of the measured area to 1 pixel or to the
average value for 9 or 81 pixels. You can display the luminance levels in the picture with different colors. This allows you
to quickly determine the overall luminance distribution in the picture, and it makes it easy
to spot overexposure, underexposure, and different luminance levels in dark areas.
On the status display, SDI signal transmission errors and various errors related to the
embedded audio signal and ancillary data can be detected. In addition, the LV 5770A has
event log, data dump, and external sync signal and SDI signal phase difference display
features for analyzing SDI signals. Ancillary data is displayed along with the embedded
line numbers and numbers of the corresponding standards in a list. This makes it
possible to display detailed analyses.
The LTC and VITC that are embedded in an SDI signal and the D-VITC that is embedded
in an SD-SDI signal can be displayed. The timecode can also be used for time stamps in
the event log. The English closed captions (EIA-608, EIA-708, or VBI) that are embedded in an SDI
signal can be superimposed over the image on the picture screen.
The LV 5770A has two external control connectors: an Ethernet port and a remote control
By connecting the Ethernet interface to a PC, you can control the LV 5770A remotely over
TELNET, transfer files over FTP, control the LV 5770A remotely and detect errors over
SNMP, and control the LV 5770A over HTTP.
The remote control connector can be used to load presets, switch the input signal, and
