Documentation Terms and Conventions
The following terms and conventions are used throughout this manual.
Terms
The following terms are used:
• “ 5.1 ” refers to 5.1 surround sound.
• “ Audio PID ” refers to the audio stream in a TS that is identified by a 13bit packet
identifier.
• “ ASI ” or “ DVB-ASI ” refers to Asynchronous Serial Interface. A standard interface for
carriage of a Transport Stream (TS) in a 270megabit/second serial digital signal.
• “ Basic Tree View ” refers to the area located to the far left of the DashBoard window.
This area displays devices in a tree structure. When you launch DashBoard, all openGear
Connect compatible devices on the same network are auto-detected by default.
• “ DashBoard ” refers to the DashBoard Control System™.
• “ Device View ” refers to the area located to the far right of the DashBoard window. This
area typically displays tabs that include menus and options for control and monitoring an
openGear Connect compatible devices.
• “ DHCP ” refers to Dynamic Host Configuration Protocol.
• “ DST ” refers to Daylight Saving Time.
• “ ES ” refers to elementary stream. One of the components of a program, such as video,
audio, or data.
• “ LTC ” and “ Timecode ” refer to Linear Timecode unless otherwise noted.
• “ MPEG-2 ” refers to a standard format for the transmission and storing of audio, video,
and PSIP data. This standard of multimedia compression is defined by the Moving
Picture Experts Group, a sub-group of the International Organization for Standardization
(ISO).
• “ MPTS ” refers to Multi Program Transport Stream. A TS that contains more than one
program.
• “ NAES ” refers to Nielsen Audio Encoding System.
• “ NTP ” refers to Network Time Protocol.
• “ Operator ” and “ User ” refer to the person who uses the NWE-TS.
• “ PID ” refers to Packet ID. A 13bit address that identifies each component of a TS. For
example, each ES and PSI table has its own PID. Some have fixed reserved values (e.g. 0
for the PAT) and others have values that are defined within the PSI.
• “ Program ” refers to a group of Elementary Streams intended to be presented together. A
television program typically contains one video, at least one audio, and possible some
data ES’s.
• “ PSI ” refers to Program Specific Information, defined by ISO/IEC 13818-1. Metadata
that describes the TS and its Programs to allow receivers to select and assemble the
appropriate components for presentation to the viewer. PSI is required in every MPEG-2
TS, including the DVB and ATSC formats. PSI consists of tables such as the PAT which
are used in both DVB and ATSC formats, and others such as the SDT which are used
only in DVB.
• “ PSIP ” refers to Program and System Information Protocol, defined by ATSC A/65. A
specification that defines metadata that is required in an ATSC TS, in addition to essential
PSI tables.
• “ SID ” refers to the Source Identification number assigned by Nielsen.
