EMR Configuration Guide WNE v.4..2 1

IntroductionReuters World News Express (WNE) is a file based television delivery system that transmits Reuters Video News(RVN) material, principally over satellite, as MPEG 2 video and XML scripts. The SkyStream Edge Media Receiver(EMR) is a DVB receiver that extracts IP content from the WNE satellite feed. This IP content is then reassembledinto video and script files by the zBand software and stored on your WNE PC.

The EMR that you will have received from Reuters with your WNE installation is shown below:

The Web-based interface for the EMR is shown below:

Although, your EMR comes preconfigured for use, there are several procedures that you must complete yourself in

order to begin receiving data from Reuters WNE satellite. Each of these procedures are described within thisdocument:

Connect the EMR to the WNE PC (described in the Physical Equipment Installation and Connections section of

this document) Tune the receiver to the Reuters Satellite signal and verify that IP data is being received and stored locally on

your WNE PC (the process by which this is accomplished is described within several sections of this document).

Abbrev iation /Term Descr iption

IFL

Generically, IFL (Intra-Facility Link) refers to a cable which runs between two facilities.

In satellite usage, the term IFL refers to the cable which connects the ODU (Out-Door-Unit) with the IDU (In-Door-Unit).

IP/DVBThis is the phrase used to describe the delivery of IP content over a DVB satellitenetwork.

Ku Band

The Ku band (pronounced "kay-yoo") is a portion of the electromagnetic spectrum withinthe microwave range of frequencies. Ku band is primarily used for satellitecommunications particularly from remote locations back to a television network's studiofor editing and broadcasting.

LAN Local Area Network

L-Band

L band is a frequency range between 390MHz and 1.55GHz which is used for satellitecommunications and for terrestrial communications between satellite equipment. An LNBis used to convert Ku and C Band frequency bands to L band, which can be transmitted

over the IFL and processed by the IDU.

LNBA low-noise block converter (LNB, for low-noise block, or sometimes LNC, for low-noiseconverter) is the (receiving, or downlink) antenna of a satellite dish commonly used forsatellite TV reception.

LOA device used to output the frequency of an incoming modulated radio-frequency carriersignal, to produce the required intermediate frequency.

MPEG Motion Pictures Experts Group. Video file format.

NIC Network Interface Card

PID (Process IDentifier) A temporary number assigned to a process or service.

URL(Uniform Resource Locator, previously Universal Resource Locator) is the uniqueaddress for a file that is accessible on the Internet.

WNE World News Express - IP file-based delivery system for Reuters news content.

Reuters Live Linear-based delivery system for Reuters news content.

The WNE PC

The WNE PC is equipped with a Stradis MPEG2 decoder card capable of playing out video content in both compositevideo and serial digital formats. The WNE PC also comes pre-installed with a second network card (NIC) which

allows video content and scripts to be transferred from it to your server infrastructure.Video stories received from the Reuters satellite can be previewed on the WNE PC via the WNE website (providedthat WNE PC has internet access). In addition, the WNE website can be used to control which video stories areplayed out via the Stradis card on the WNE PC (refer to the Online Help system within the WNE website forinstructions on how to do this).

Supplied Equipment

The standard equipment supplied by Reuters with your WNE installation includes:

EMR satellite receiver

Accessing the EMR via the web interfaceThe most efficient method by which to configure your EMR is via the web-based interface.

1. Turn on your EMR and the WNE PC. Accessing the EMR through the WEB GUI requires that both devicesshare the same subnet address. All EMR LAN 2 ports default to an IP address of 172.16.2.2. (LAN 1 is suppliedwith a default of 172.16.1.2).

2. Change the IP address of the onboard NIC to match the subnet address on the EMRs LAN2 port (e.g.172.16.2.100), with a Subnet Mask of 255.255.255.0.

3. Enter the LAN 2 EMR IP address into an internet browser window.

Note:A shortcut link may already exist in your browsers Links section called Skystream Networks Edge MediaRouter(also accessible via 172.16.2.2).

4. The following EMR page will then be displayed. If you select one of the menu options in the left hand navigationbar, you will be prompted to login (as shown below).

Figure 3 EMR web interface with login page

5. To login, enter the default useremradmin. No password is required.

Note: If you are accessing the site for the first time or have just rebooted the EMR, you must supply the default username. Otherwise, you will generally not be prompted for a login.

The initial connectivity between your WNE PC and EMR has now been established. Next, you will need toensure that you have signal lock to the satellite.

Locking to the WNE signal1. Select Satellite Receiverfrom beneath the Statistics menu in the left hand navigation bar. The Statistics-

Satellite Receiverpage will display the NO LOCK status for the key values shown below. This indicates thatsatellite parameters have not yet been entered into the EMR.

Figure 6 Tuner conf iguration page

4. Enter the parameters for the satellite that is applicable to your location. Refer to the tables in Figures 1 and 2 ofthe Global Satellite Coverage section of this document for the relevant regional downlink parameters. Thesettings you must reference are the D/L Frequency (L-Band Frequency), Symbol Rate and Polarization.

L-Band Frequency is o ften noted as:

KU Band Downlink Frequency LNB LO Frequency.

C Band LNB LO Frequency Downlink Frequency

A high proportion of LNBs used by subscribing Reuters Live clients tend to have a LO (Local Oscillator)frequency of 10GHz. In the example in Figure 6 above, the L-Band Frequency value is 1200MHz.

In the example below, for an EMR unit in Europe, the frequency value is obtained by subtracting the D/L SatelliteFrequency value from NSS-7 for the Europe region (see Figure 1) from a local oscillator (LO) frequency of10GHz or 9.75GHz.

A few sample calcu lations are show below:

10GHz LO i.e. 109857 MHz 10000MHz = 985.7MHz.

9.75GHz LO i.e. 109857 MHz - 9750MHz = 1235.7MHz.

5. Once the correct parameters have been entered, clickApply to accept the changes. If the entered parametersare correct, the Configuration - Tuner 1 page will be displayed. The Data Lock (FEC lock) field should nowdisplay a green lock (as shown in Figure 9). This indicates that the EMR has locked to the WNE satellite signal.

Note: If a red light initially appears in the Data Lock (FEC lock) field, press F5 to refresh. The green lock lightshould then appear in that field.

Figure 7 Successful data lock

Note: Refer to the Troubleshooting section at the end of this document if the signal has not locked.

6. Once you have successfully locked onto the Reuters signal, you must configure the EMR to extract the IP datafrom the satellite signal. This will include setting the relevant PID for the signal. Packet IDs (PIDs) are identifiersused to tag different MPEG component packets within a satellite signal (e.g. video, audio or in the case of WNE,IP data). WNE IP data is carried within the satellite signal on PID 3550.

Select PID Selection from the Configuration menu in the left hand navigation bar. The Configuration PID

Selection page will be displayed.7. Click PID Selection. The PID Selection Receiver 1 page will then be displayed.

9. The EMR is now successfully locked to the WNE signal and is extracting IP data from the appropriate PID value.All IP data is carried on a multicast IP address and must be routed to the relevant EMR Ethernet port (e.g.,Ethernet 2/LAN2). Standard WNE installations send received content through Ethernet 2 port on the EMR.

10. In order to distinguish between the different transmission standards, PAL (625) and NTSC (525), each formatexists on a separate multicast address. These are provided below:

Transmission paths multicas t addresses

525 Satellite Transmission Path 224.14.14.14

625 Satellite Transmission Path 224.14.14.15

11. Select SkyCast from the Configuration menu in the left hand navigation menu. The Configuration - SkyCastpage will then be displayed.

12. Click Edit on themulticast IP address (224.14.14.14 or 224.14.14.15).The Edit SkyCast Rule page will bedisplayed. Select the Forward and Ethernet2 options in theAc tion field for thismulticast address.

Figure 9 SkyCast Rule for the EMR

13. ClickApp ly to designate that IP data should be sent to Ethernet 2 and confirm your SkyCast Rule settings.

14. Your IP data should now be being received and processed correctly.

You can verify data reception via the Network Interface Traffic and Statistics - Skycast pages. You canaccess these pages by selecting the Network Interface orSkyCast options from the Statistics menu in the lefthand navigation bar.

15. Be sure to save all the configuration values you have just set to a conf iguration file! The process by whichto do this is described in the Saving a Configuration File section of this document.

Saving a configuration fi leOnce the EMR is correctly connected to the WNE signal, extracting IP data from the appropriate multicast addressand forwarding this IP data to Ethernet 2, this configuration should be saved as the default setting.


15/18


1. Select Configuration Filefrom the Maintenance menu in the left hand navigation bar. The Maintenance-Configuration File page will be displayed.

Figure 12 Default configuration f ile for an EMR

Note:A default configuration file may already exist for this EMR. However, it is recommended that a new default filebe created with the settings you have just configured. This default profile will then be loaded whenever the EMR isrebooted. In addition, if during the routine operation of your EMR, you or a Reuters support representative makeany changes to the configuration settings of the EMR, you should save these changes to the configuration file toensure that they are preserved whenever the EMR is rebooted.

2. Set the following fields on the Maintenance-Configuration File page:

Enter a suitable name for this configuration in the Save current configuration as field.

It is recommended that you enter the date that the profile was created In the Configuration descriptionfield.

Ensure that the Default option has been selected.

3. Once these details have been entered, click Save to save this configuration.

4. It is recommended that you now reboot the EMR to ensure that the configuration is loaded correctly upon startup.

5. To reboot, select System Reboot from the Maintenance menu in the left hand navigation bar. A Reboot Nowbutton will be displayed. Click it. The EMR requires approximately 60 seconds to fully reboot and lock onto theWNE signal.

You EMR configuration is now complete.

Note: If the configuration file is not correctly loaded when your EMR is rebooted, ensure that you have properly setall your configuration settings and saved them to the configuration file or contact a Reuters support representative

for assistance.

Troubleshooting

Unable to lock to the WNE signalItems to verify:

Verify the LNB values that have been entered (refer to Figures 7 & 8). Several WNE installations haveuncovered a d ifferent LNB value when examined by an engineer. For example, if it is believed that a 10GHzLNB is installed, try altering the L-Band frequency value by 500MHz.

Check the quality of the RF coaxial cable connecting to the EMR. The F connector is a type of coaxial RF

connector commonly used for:
