PDC Program Delivery Control (VBI).
PDC is specified by the standard ETS 300 231, published by the European
Telecommunications Standards Institute (ETSI). This specifies the signals
sent as hidden codes in the teletext service, indicating when transmission
of a program starts and finishes.
PES Packetized Elementary Stream
A specification in the MPEG-2 Part 1 (Systems) (ISO/IEC 13818-1) and ITU-T
H.222.0[1][2] that defines carrying of elementary streams in packets within
MPEG program streams and MPEG transport streams [3]. The elementary
stream is packetized by encapsulating sequential data bytes from the
elementary stream inside PES packet headers.
PID Packet Identifier
A unique integer value used to identify the contents of an MPEG-2
Transport Stream packet (Video component PID, Audio component PID,
etc.).
Profile A defined subset of the syntax specified in the MPEG-2 or MPEG-4 video
coding specification.
PMT Program Map Table.
A mandatory MPEG-2 PSI table. Each service has a PMT. It lists the service
component parts (elementary streams of video, audio, location of the PCR
fields, etc.).
PSI Program Specific Information.
Normative data that is necessary for the demultiplexing of transport
streams and the regeneration of programs.
PSIP Program and System Information Protocol.
A method of describing Naming and Navigation data for a multi program
transport stream as defined in ATSC A/65A.
PSU Power Supply Unit.
PTS Presentation Time Stamp.
The PTS is a metadata field in an MPEG transport stream that is used to
achieve synchronization of programs' separate elementary streams (for
example Video, Audio, Subtitles) when presented to the viewer. The PTS
is given in units related to a program's overall clock reference, either
Program Clock Reference (PCR) or System Clock Reference (SCR), which is
also transmitted in the transport stream or program stream.
PVR Personal Video Recorder.
QCIF Quarter Common International Format.
To have one fourth of the area as "quarter" implies the height and width of
the frame are halved (video size: 176p x 144p).
QSIF Quarter Screen International Format.
To have one fourth of the area as "quarter" implies the height and width of
the frame are halved (video size:160 x 120 pixels (NTSC) or 192 X 144 pixels
(PAL).
QVGA Quarter Video Graphics Array.
QVGA is a popular term for a computer display with 320×240 display
resolution.
