2.1 Product Overview

The LV 5330 is a multi SDI monitor with support for HD-SDI and SD-SDI. In creating the LV 5330, we prioritized on-site use. This has led to a compact, light, energy-saving design. With its wide range of features, including picture display, video signal waveform display, vector display, audio level display, error detection, and data analyses, the LV 5330 can be used for both high-precision measurement and monitoring. The LV 5330 also comes standard-equipped with CINELITE II, a powerful tool for analyzing video signal luminance data, and an analog input connector that enables the LV 5330 to be used as a camera viewfinder.

2.2 Features

• SDI I/O
The LV 5330 has two SDI input connectors that can be used for both HD-SDI and
SD-SDI input. It also has an SDI output connector that you can use to send a reclocked
SDI signal.
• View Finder Input Connector
2. Specifications
The LV 5330 can receive and display analog composite signals (NTSC and PAL). It
comes with a peaking feature that assists in focus adjustment.
• TFT LCD
The LV 5330 has an XGA (1,024 × 768) 6.5-inch color TFT LCD.
The LCD can display video signal waveforms, vectors, pictures, audio levels, and status
information.
You can also view combinations of these items using the LV 5330 multi-screen display
feature.
• Picture Display
The LV 5330 uses fully digital waveform display processing to achieve high precision and
versatility. The display has a number of adjustment features such as color temperature
selection, brightness adjustment, contrast adjustment, aperture adjustment, and chroma
gain adjustment. It also has monochrome and safety marker display features.
• CINELITE II
The LV 5330 comes standard-equipped with CINELITE II (CINELITE and CINEZONE),
which is a video signal luminance information analysis tool.
With CINELITE, you can use the cursor to select any 3 points and display their f-Stop
numbers, percentage values, and 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.
With CINEZONE, you can display the luminance levels in the picture using 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.

2. Specifications
• Video Signal Waveform Display
The LV 5330 uses fully digital waveform display processing to achieve high precision and
quality. From video signal waveform display gain expansion, sweep expansion, and
cursor measurement to pseudo-composite and RGB displays, the LV 5330 has all of the
features that people look for in a waveform monitor. The LV 5330 is equipped with an
external sync signal input and it can display video signal waveforms based on a tri-level
sync signal or an NTSC or PAL black burst signal.
• Vector Display
The LV 5330 can display component chrominance signal vectors.
The amplitude can be manually zoomed, or set to a fixed magnification value such as
five.
The IQ axes, which are useful for vector observation, can be turned on and off.
• 5 Bar Display
The LV 5330 can display the peak levels of the Y, R, G, B and pseudo-composite signals.
This feature is useful for monitoring gamut errors.
• Audio Level Display
The LV 5330 can extract the audio signal embedded in an SDI signal and display levels
and values for up to eight channels. (The maximum SD-SDI audio quantization level is
20 bits.)
• Stereo Headphone Output
The LV 5330 can extract the audio signal embedded in an SDI signal. You can select two
channels from the extracted audio and transmit them in stereo through the headphone
output connector.
• Status Display
The status display has a number of advanced features, including SDI signal error
detection and analysis features.
• Error Detection The error detection feature can help you to catch transmission errors such as CRC errors (HD-SDI), EDH errors (SD-SDI), BCH errors, and checksum errors.
• Event Log The ability to log events such as detected errors and input signal switching makes long-term error monitoring easy. The event log can be saved to USB memory or sent to a PC through an Ethernet connection as text data.
• Data Dump The ability to display digital data after parallel conversion in hexadecimal or binary format is useful when there is a problem and is also useful for various kinds of data analysis. Data dumps can be saved to USB memory or sent to a PC over an Ethernet as text data.
• Packet Analysis The LV 5330 can analyze and display the various packets embedded in an SDI signal.
2-2
2. Specifications
• Time Code Display
The LV 5330 can decode SMPTE RP-188 time codes (LTC or VITC) and display them. These codes can be used as timestamps in the event log.
• Screen Capture
The display can be captured. Captured displays can be viewed or superimposed over an input signal. Captured displays can be saved in internal memory (RAM) or USB memory or sent to a PC through an Ethernet connection as bitmap data.
• Presets
The LV 5330 can remember up to 30 frequently used setting configurations. The configurations can be recalled easily from the front panel or using commands sent through the Ethernet or remote connector.
• Remote Connector
You can recall presets by sending commands through the remote connector. Also, a tally light can be displayed on the screen.
• Ethernet Connector
From a PC connected to the LV 5330 through the Ethernet connector, you can recall presets, execute panel operations, transfer files, and monitor errors.
• Last Memory
The LV 5330 backs up the current settings so that you can use the same settings that you were using before immediately after powering it up.
• 75-mm VESA Mounting
The LV 5330 has 75-mm VESA mounting holes on its rear panel that allow it to be mounted on an arm or stand.
• Tripod Attachment
The tripod adapter on the bottom of the LV 5330 can also be removed and placed on the top.
• Power Supply
The LV 5330 has an XLR DC input connector and runs on a 12-VDC power supply. As a factory option, a battery adapter can be attached to the rear of the LV 5330. With this option, the LV 5330 can use the kinds of batteries that are used in video cameras and other equipment. (The 75-mm VESA mounting holes cannot be used if the LV 5330 has a battery adapter attached to it.)
* Ethernet features (SNMP) and the battery option will be supported in the future.
