Program Stream/Private Stream
A Program Stream is a bitstream containing multiple
streams related to a single audio/video programs. A
Private Stream is a stream not further defined by
MPEG-2 but accommodated.
Program Specific Information
Presentation Time Stamp
Presentation times of presentation units extracted from
the PES (Packetized Elementary Stream) headers. Used
by the L64105 to display fields from the frame stores.
Pixel Data
A pixel is a display position on a horizontal scan line of a
TV picture. Pixel data is color to be displayed and is
usually encoded into 8 bits.
Random Access Memory
A memory that requires continuous power and that can
have any location addressed randomly.
Reduced Memory Mode
The L64105 normally uses three frame stores in SDRAM
for reconstruction and display of video frames. I and P
frames require two full frames stores. A third frame store
is used exclusively for B pictures. When SDRAM space
is limited because of the large space required for PAL
images or because large OSD areas are being used, the
B frame store space can be reduced. This means that the
decoder overwrites the part of the B frame that has been
displayed and does limit some trick mode features.
