  • Page 7: Dvb+ Satellite Receiver: Overview

    DVB+ Satellite Receiver: Overview The Mainstream Data DVB+ Receiver, shown in Figure 1, tunes and demodulates a Digital Video Broadcast-S, L-band RF signal input to provide data output. The DVB+ extracts IP multicast packets from MPE sections and passes them out the Ethernet port based on the authorized Program Identification Descriptions (PIDs) and multicast addresses.

  • Page 8: Safety Issues And Precautions

    This guide provides the high level information needed to understand the DVB+ Receiver in its operational context. Site- or customer-specific information is not provided here. Typically a Mainstream Data customer service representative or a network operator supplies the detailed settings, procedures, and contact number for specific sites.

  • Page 9: Installing The Dvb+ Satellite Receiver

    Installing the DVB+ Satellite Receiver This section summarizes the steps involved in setting up the DVB+ Satellite Receiver. After cables are connected, you will need to verify or establish DVB+ settings through the front panel LCD. This information is covered in the next section, “Understanding DVB+ Settings” Note: If you do not yet know the expected E reading and AGC levels for the site, contact the network operator now.

  • Page 10: Step-By-Step Procedures

    Installing and verifying DVB+ operation requires use of the LCD front panel. If you have not previously installed Mainstream Data receivers or are unfamiliar with using the front panel, refer to the next section, Understanding DVB Settings for the appropriate information on using the panel.

  • Page 11: Step 2: Verify Initial Lock On Carrier

    Step 2: Verify Initial Lock on Carrier As soon as power is applied to the DVB+, an automatic self-test runs. The DVB+ then attempts to locate and lock onto the preset carrier. If a DVB carrier is not found the DVB+ toggles back and forth between the primary and the alternate carrier until a lock is obtained on one of the channels.

  • Page 12: Step 3: Verify Signal Strength

    Step 3: Verify Signal Strength Signal strength quality is indicated mainly by the E reading in the Show Tuner Status screen. It is possible to fine tune that reading by slightly adjusting the position of the satellite dish. The E should be at least 5.0, usually higher, depending on environmental conditions.

  • Page 13: Step 5: Verify Data Output

    Step 5: Verify Data Output If you are using the Serial port, you can verify its data output by performing various test functions: 1. Request a test transfer from the NOC. 2. Connect the RS-232 cable to a computer and run Windows HyperTerminal to check receiver settings.

  • Page 42: Ip Remap Web Page

    IP Remap Web Page IP remapping, sometimes called Network Address Translation (NAT), is useful in situations where existing applications running on the local LAN are already using a specific IP address. You can remap an IP address on the DVB+ to prevent addressing conflicts. Figure 26 IP Remap Web Page The IP remapping applies only to the DVB channel and not to the Aux channel.

    Functional Overview This section contains background information on data flow through the network and on the functionality of the DVB+ Satellite Receiver. Network Overview The DVB+ Satellite Receiver provides data out by extracting IP multicast packets from MPE sections and passing them out the Ethernet port labeled on the receiver as DVB Channel. The unit extracts IP multicast packets from MPE sections based on the specified Program Identification Descriptions (PIDs) and multicast addresses.

    It is common for a satellite service to have a backup carrier that will be used in the event the primary carrier fails. The DVB+ has the means to store two settings for carrier parameters (MAIN and ALT), and if configured properly, checks for a valid carrier at the alternate frequency if the primary carrier becomes unavailable.
  • Page 53 DVB Decryption Each PID stream can be decrypted by the DVB decryption process. Feeds that are not DVB encrypted are unaffected by the DVB decryptor. Decryption requires the proper key values and proper setting of the conformance bit, each of which can be downloaded or entered from the Web page or LCD display, unless such access has been denied by the operator.
