Category: Video servers/encoders

Type: User manual

Radiant Communications QRF-5000-Rackmount Rev G2 is a highly integrated, technologically advanced encoder and QAM modulator used to insert one or more local video feeds into a digital cable system. It consists of up to four real-time, hardware-based MPEG-2 encoders and Dolby Digital 2.0 AC3 audio encoding. The unit will encode, and packetize incoming signals and then multiplex them so that they can be digitally QAM modulated in preparation for final RF agile up-conversion.

1. Introduction

The Radiant Communications Corp. QRF5000 series is a highly integrated, technologically advanced family

of products used to insert one or more local video feeds into a digital cable system. The QRF5000 series

consists of several products which work seamlessly together, or completely independent, to fulfill specific

individual requirements in a cost effective, efficient and flexible manner.

QRF5000

Video is encoded with up to four high quality, real time, hardware based, MPEG-2 encoders and audio is

encoded using Dolby Digital 2.0 AC3 encoding. The units will encode, and packetize incoming signals and

then multiplex them together so that they can be digitally QAM modulated in preparation for final RF agile

up-conversion.

QRF5000DQ

The QRF5000DQ contains a digital QAM tuner module, which can be configured to tune to any channel

within a standard cable lineup. Once tuned, the user is shown a list of services which are within the digital

channel. The users can than select which services to keep, and which services to remove. In conjunction

with the up to three installed encoders and external RF Notch Filter, the user can add local video to an

existing digital QAM. This allows for maximum bandwidth allocation and provides a path for head end

communications to reach a digital QAM tuner in the case where set top boxes are not used. This is

important for applications where such signals as E.A.S are required.

DC Power, FAN and I/O

The unit is powered by 9V DC @ 4A power supply.

Four port I/O connector is not used at the moment.

Audio Inputs

Each encoder supports two channels of audio. A dual vertical stacked RCA connector is available.

Video Inputs

Each encoder supports one video input and can be either an S-Video or Composite video input. A

BNC connector is available for the composite video and an S-Video DIN connector is available for

the S-Video input.

ASI Input

To allow for channel expansion an MPTS ASI input is available on all QRF products. . A BNC

connector is available for the MPTS ASI input.

ASI Output

The QRF5000 transmits an ASI output which is the multiplexed MPTS ASI stream containing the

encoders, ASI and RF inputs.

RF Input

The QRF5000 receives its input via a 75Ω F-Connector. This should be connected to the RF cable

feed for tuning and decoding of digital QAM signals.

RF Output

The QRF5000 transmits an RF output which is the QAM modulated MPTS ASI stream up-

converted to the user’s desired frequency.

Menu Navigation

Menu items are highlighted using the Up and Down keys and selected using the right or Enter keys.

The Left key will back out of a menu into the previous menu and the Plus and Minus keys are used

to increment and decrement digits. The Enter key must be depressed in order to save a selection or

setting.

Selecting and Saving Settings

When a selection is confirmed using the Enter key a “Saving Changes” message will appear.

Loading Defaults

The original factory settings can be loaded by navigating to the System | Load Defaults menu and

selecting Yes.

All settings are stored in FLASH and will be remembered after power cycles.

Controlling the unit via Ethernet

The QRF5000 series can easily be controlled remotely via an Ethernet

connection using Radiant Communications RepManager Software.

The first task is to discover the unit(s).

QRF5000 RevG2 Series Installation and Operation Manual

Page 11

Once the units are discovered, they can be easily configured, upgraded or restarted. If the units are

discoverable, but not on the same subnet, you will prompted with the ability to temporarily change the units IP so

that you can communicate with it.

Configuring the unit

After selecting the unit you wish to configure by highlighting the units IP, select the configure

button. If the password has been modified from the default ‘0000’, the following dialog box will appear.

After entering the proper password, you will see the following dialog box.

The tuner page allows you to easily add and remove program filters.

Updating Client Software

To update a QRF5000 series product, simply highlight the unit you wish to update, and select the

Upgrade option. You will be prompted for an upgrade file. (Contact Radiant Communications

Technical support for questions regarding unit upgrades)

Auto Match PIDs Procedure

The “Auto Matching PID’s“function from Radiant Communications is an easy way for the QRF

product family to add local video insertion without having to worry about potential PID conflicts.

The QRF can automatically assign PID values that match values from services in the incoming

QAM. These are normally services that are to be dropped and replaced with the local services.

 Discover the QRF5000

o The units are shipped from the factory with a DHCP enabled. When discovered with the

GUI, the units will have 169.x.x.x IPs.

o Highlight the unit and click

Network Settings

. This will set the device to a temporary IP

address. This temporary IP is intended to allow communication with the device if it is not presently

on the same subnet as the PC.

o Click ‘Discover’ than highlight the unit with the temporary IP and click

Configure

o Under the ‘General’ tab, change the network settings. Uncheck DHCP and enter the new

static IP, Subnet and Gateway. Click

Save

and

Yes

on the new window to confirm the changes, and

reset of the unit.

 Program the tuner

o If not already open, launch the configuration editor for the QRF in question, by highlighting

the unit in the REP Manager and hitting ‘Configure’.

o Under the Tuner tab, enter the frequency and QAM mode of the incoming QAM channel

that you wish to drop and replace.

o Highlight the program(s) that you wish to filter and press the arrow button.

o The left table shows ALL services found at this frequency. The right table shows services

that are being filtered.

 Auto match PID’s.

o Go back to the REP MANAGER main screen, and highlight the unit that was just

configured.

o From the ‘Device’ Menu, click

Auto Match PIDs

o Click the ‘

Set Using Active Services’ link

. This will open another dialog box which will

contain a drop down list of all the services found on the tuner. Select the Encoder1 tab, and also

the service which you wish to drop. Click ‘Match’ and all PID’s for this service will be set to that of

the incoming stream.

o Repeat for

Encoder 2,

make sure to select Encoder2 tabs when doing so.

o Click ‘Save’ to Save and apply all settings.

Cable Modem Setup Procedure

The QRF5000 series can easily be controlled remotely via an Ethernet connection using Radiant

Communications RepManager software.

Successful Ethernet connection could be established by following the steps below. This procedure

can be done on all QRF5000 Series units.

 Install the Radiant Communications RepManager software on the management PC. The

latest version of the software could be obtained from the CD included with the unit or by

downloading it from http://support.rccny.com/qrf .

 Connect the QRF-5000W Series unit to the cable modem using Ethernet RJ-45 cable. The

network port is located on the front panel of the QRF-5000W unit.

 Configuration:

 Configuration using the controls on the front panel of the unit.

The units are shipped from the factory with a DHCP enabled. If your network doesn’t contain a

working DHCP server, a static IP within the subnet must be assigned to the unit.

Below is the menu tree structure of the network parameters. All defaults are in bold or in

parenthesis:

o System

 Network

o IP Mode

 Static

 DHCP

o Static IP

 Set Static IP using left, right, and +/- keys

o Status

 Displays the IP Configuration

o Advanced

 DHCP Fallback

 Set the DHCP Fallback Address

o Configuration using the RepManager Software.

 Discover the QRF

 The units are shipped from the factory with a DHCP enabled. When

discovered with the GUI, the units will have 169.x.x.x IPs.

 Highlight the unit and click

Network Settings

. This will set the device to a temporary IP

address. This temporary IP is intended to allow communication with the device if it is not

presently on the same subnet as the PC.
