TERMS AND DEFINITIONS
This document defines the following terms:
CA – Conditional Access – Conditional Access systems restrict television program access to certain groups of users either because of concerns for privacy or the desire to collect revenue for the service.
CAT – Conditional Access Table – Tables that are designed to deny general users access to premium or otherwise restricted content, and to establish protocols and systems to grant authorized user’s access
ECM – Entitlement Control Message – an encrypted message that is used to prevent unauthorized reception for such services as cable or satellite television.
EMM – Entitlement Management Message – an encrypted message that contains private conditional access information about the authority a viewer has to acquire reception for such services as cable or satellite television.
ES – Elementary Stream – Defined by MPEG-2 Systems (ISO/IEC 13818-1). An elementary stream contains only one kind of data, e.g. audio, video or closed caption. An elementary stream is often referred to as “elementary”, “data”, “audio” or “video” bit streams or streams.
IGMP- Internet Group Management Protocol – A protocol that hosts use to keep local routers informed of their membership in multicast groups. When all hosts leave a group, the router no longer forwards datagram’s that arrive for the group.
MPTS – Multi-Program Transport Stream – Transport Streams are the combining (multiplexing) of multiple program channels (typically digital video channels) onto a signal communication channel (such as a satellite transponder channel). A MPEG transport stream (MPEG-TS) may also called a multi-program transport stream (MPTS) and at other times a SPTS.
NIT – Network Information Table – Describes how transport streams are organized on the current network, and also describes some of the physical properties of the network itself. The NIT also contains the name of the network, and the network ID. This is a value that uniquely identifies the network that is currently broadcasting the transport stream, and may be different from the original network ID that we discussed earlier, if the transport stream is being rebroadcast.
PAT – Program Association Table- Each Transport Stream contains one or more Transport Stream packets with PID value 0x0000. These Transport Stream packets together shall contain a complete Program Association Table (PAT), providing a complete list of all programs within the Transport Stream.
PCR – Program Clock Reference) – The program clock reference (PCR) is transmitted within a video transport stream as a time reference. A sufficiently accurate and correctly received PCR is a precondition for correct data display in the receiver.
PID – Packet ID- Packet identifier; a unique 13-bit value used to identify the type of data stored in the packet payload (see ITU-T H.222.0 / ISO/IEC 13818-1).
PMT – Program Map Table – A specific PID within a transport stream which provides the mapping between a program number and the program elements it is comprised of. It contains a minimum of a program number, PCR PID, stream types and program element PIDs.ANSI SCTE 154-4 pdf download.
