Table 1.3: Glossary of Terms

 

 

Term

Definition

 

 

Automated

The mechanism used when the U4600 is unable to acquire a valid transport stream, loses network

Recovery

control or detects an invalid control stream, or is unable to deliver the required services using its

(or Recovery)

current settings. The unit automatically begins attempting operations under "backup" unit settings

stored in the presets table until it can return to normal operation or is stopped by local user

 

 

command.

 

 

Boot loader

Software residing in non-writable zone of flash which executes at unit reset. It will verify and load the

 

preselected application.

 

 

CA

See "Conditional Access".

 

 

COMPEL®

Wegener's network control software that may be used to manage your U4600 as well as other

 

hardware.

 

 

Conditional Access

Wegener’s system for securing the transmitted transport stream from unauthorized access. It

 

features distribution of ciphered authorizing messages within a special PID. Upon deciphering in

 

secure processors within the IRD, these messages continuously update the IRD with the current

 

descrambling key.

 

 

DPI

Digital Program Insert. A special message, borne in an MPEG PID associated with a particular

 

program, that signals the boundaries of ad avails.

 

 

DTMF

Dual-Tone Multi-Frequency. Tone signaling system used by the legacy telephone system. Tone

 

pairs represented each of the keyboard items 0-9, *, and #. This system may be used to control

 

external cueing equipment.

 

 

DVB

Digital Video Broadcast working group. This is a shorthand designation for a group of industry

 

standards that provide enhancements in the use of MPEG transport streams. (For example, one

 

DVB standard defined the standard way QPSK-modulated carriers would convey these streams

 

over satellite world-wide.)

 

 

Eb/N0

Energy-per-bit per Noise density-per-Hertz. This is a unitless ratio that expresses signal-to-noise

 

ratio in carrier transmission systems that convey digital data. A quality measurement for any such

 

system is the E b/N0 needed to just convey the digital data within acceptable error rates. This is called

 

the “Eb/N0 threshold”.

 

 

Ethernet

The widely-used LAN technology specified by IEEE standard 802.3

 

 

IRD

Integrated Receiver-Decoder. A product which features a "receiver" to extract transport streams

 

from satellite-borne carriers and a companion "decoder" to decompress MPEG elementary streams

 

(from within said transport streams) in order to recreate the original audio/video/data signals. The

 

Unity 4600 is an IRD.

 

 

Keep-alives

Simple COMPEL network messages, addressed to "all", bearing date and time.These are

(COMPEL)

transmitted regularly (every 5 seconds, for example) so that IRDs may quickly and continuously

verify their network connection.

 

 

 

KMS

Key Management System. The sub-system within the Wegener Conditional Access system that

 

creates and ciphers the scrambling keys and then distributes them to the uplink UMX5010 and all

 

downlinked IRDs conveyed in a special PID within the transport stream.

 

 

LAN

Local area network. Your U4600 may be connected to an Ethernet LAN.

 

 

LCD

Liquid crystal display. The front-panel screen on your U4600 is a liquid crystal display.

 

 

LED

Light-emitting diode. The front-panel indicator lights on your U4600 are LEDs

 

 

Mbps, kbps or Msps

Units of data transport rate - Megabits per second (1 million bits per second), kilobits per second (1

 

thousand bits per second), or million symbols per second (1 million symbols per second)
