Glossary of Terms and Abbreviations
Sony/Phillips Digital Interface
A specification for forming encoded or unencoded audio
into bursts and coding the bits to reduce the DC
component of the bitstream, facilitate clock recovery, and
make the interface insensitive to the polarity of the
connection.
Start of Active Video
The end of vertical blanking and the start of the active
area of video. See CCIR656.
System Clock Reference
In MPEG systems, a 90-kHz Systems Time Clock (STC)
is used as the reference time base. The current STC time
is included in MPEG bitstreams in SCR fields spaced no
further apart than 700 ms. Audio and video PTSs
(Presentation Time Stamps in the PES packets are
compared with the SCR for display and audio
synchronization
Synchronous Dynamic Random Access Memory
DRAM that requires a clock interface signal for data
transfers.
Thin Quad Flat Package
Trick modes are those modes of display, such as slow
play, pause, etc., that require skipping or repeating fields.
Transistor-Transistor Logic
A digital signal interface convention that defines particular
levels between 0 and
and HIGH-to-LOW switching points between logic 0 and
logic 1.
Vdc that are the LOW-to-HIGH
