Introduction

Overview

These 3RU and 4RU rack-mounted MPEG/Video/Audio monitors arethe new benchmark in LCD monitors for broadcast and professional video applications requiring support for both file-based and traditional baseband sources. The monitor has 800 x 480 screen resolution, antiglare TFT screens, and fully digital signal processing. It supports H.264/MPEG-4 Part 10, also known as AVC/H.264 or Advanced Video Coding. It also supports H.262/MPEG-2 Part 2. These are decoded from MPEG-2 TS (Transport Stream) containers in ASI or IP transport interfaces. The TS container format can be either 188 bytes or 204 bytes. Error correction bytes are not used. It does not decode encapsulated transport streams in other formats, such as QuickTime (MPEG4/ H.264). The MPEG-3270 and MPEG-4290 also support 3G/HD-SDI and HDMI. All video formats are scaled to native screen resolution in the highest quality using precision scaling and gamma correction to produce the best images available.

CHAPTER 1

Installation

This chapter contains detailed information on safety and installation requirements. It also contains an overview of the front and back panel controls, connectors, and screen features. To quickly unpack and set

up this unit for monitoring, please refer instead to Chapter 2: Quick Start.

Safety

Important Safety Instructions

WARNING:

IMPORTANT:

Do not use this equipment near water, rain or moisture.

1. Read, keep, and follow all of these instructions; heed all warnings.

2. Use only a dry cloth to clean the equipment.

3. Do not block any ventilation openings. Install only in accordance

with the instructions in the section entitled, “Installation

Recommendations” on page 3.

4. Do not install near any heat source such as a radiator, heat register,

amplifier, or stove.

5. Do not expose the equipment to rain or moisture.

6. Do not attempt to plug the unit into a two-blade outlet (with only

two prongs of equal width).

By design, these audio/video monitors will only plug into a threeprong outlet for your safety. If the plug does not fit into your outlet, contact an electrician to replace the obsolete outlet.

7. Protect the power cord from being walked on or pinched,

particularly at the plug’s source on the equipment and at the socket.

8. Use only the attachments/accessories specified by the

manufacturer.

9. Refer all servicing to qualified service personnel. Servicing will be

required under all of the following conditions:

8 21 0 6 8 : MPE G - 3 2 70 & 4 2 9 0 U ser G u i de

• The equipment has been damaged in any way, such as when

• Objects have fallen onto the equipment; or the equipment has

• The equipment does not operate normally.

• The equipment has been dropped.

been exposed to rain or moisture, or liquid has been spilled onto the equipment.

WARNING:

The symbol to the left warns of electric shock hazard inside the unit. Disconnect the power cord before removing access panels when installing upgrades. Only qualified service personnel are to operate the equipment with covers removed, and are to exercise caution to avoid personal injury or damage to the equipment from overheating.

Installation Recommendations

Mounting

These units are designed to install into a standard 19" rack mounted at eye level for best visual observation of the monitor screen. Please adhere to the following clearances to provide adequate ventilation:

Clearance Surface

24” Front

3” Rear 2” Sides

1.75” Top and Bottom

Heat Dissipation

These monitors contain two very quiet fans, so no special physical mounting considerations are necessary regarding heat dissipation except under adverse conditions, provided the ambient temperature inside the mounting enclosure does not exceed 40°C (104°F).

Adjacent devices can be rack mounted (or stacked) in proximity

to the unit. If the temperature is above 104°F (40°C) allow an additional 1RU 1.75” (44.45mm) space above and below the unit for air circulation.

DC Power

The MPEG-3270 and MPEG-4290 require 24 VDC at 3 Amps. They cannot be harmed by accidental reverse connection of power.

• F3 button is labeled IMD. It is planned in future software

releases that this function button will, by default, control the appearance of IMD displays, however in the current software release, this button is unassigned.

• F4 - F6 buttons are unassigned, but may be easily assigned to

control various functions. Refer to the Functions Menu on

page 37.

• HDMI: Pressing this button lights its indicator and selects the

HDMI input, deselecting the Ethernet and SDI/ASI inputs. Refer to the Status Menu on page 47 for details on setting the HDMI audio channels to monitor.

• ETHERNET: Pressing this button lights its indicator and selects the

Ethernet input connection as the MPEG source, deselecting the HDMI and SDI/ASI inputs. Refer to MPEG Screen Operation on

page 23 for further details.

• SDI/ASI: Pressing this button lights its indicator and selects the

HDMI input, deselecting the Ethernet and HDMI inputs. It also toggles between the SDI input sources for each screen: SDI-A (SDI or ASI) and SDI-B (SDI or ASI). Selecting SDI-A is indicated by the

A LED; selecting SDI-B is indicated by the B LED. Since these

inputs can be more than one type, you must select the exact input type from the System Menu. Refer to the System Menu on page 42 for details.

• Menu/Back: Pressing the Menu button displays the Main Menu.

Pressing it again returns you to the previous menu or to the Main

Screen from the Main Menu. Refer to Using the Menu System on

page 30 for more information.

• Volume/Enter: Rotating this knob when a menu is not displayed

increases or decreases the audio volume of the selected video stream. Pressing or turning any Volume knob selects the audio of that screen for monitoring and mutes or unmutes the audio. The

Volume knobs are also used to adjust options within the menu

system.

• LCD Screen: The LCD screens display the selected video and OSD

features. For MPEG video, they also display data and PID (packet identifier) tables and other useful information.
