Profile PRO Series
P Picture
A P picture is a predictive picture used in MPEG video compression. MPEG
uses motion prediction to increase efficiency, that is, it reduces data by not
duplicating pixels that do not change from frame to frame. A P picture relies
on data from forward-moving motion vectors to determine how a future
frame will be composed. See B Picture, GOP, I-frame.
Protocol
A set of rules that allows computers to transfer information across a network
to other computers.
Read-only memory (ROM)
Memory that is not erased when power is turned off. It is also called
firmware. The firmware in a computing device allows it to boot without
being connected to a host computer.
Real-time
Generally considered to be 30 fps in NTSC, 25 fps in PAL, 24 fps for film.
In computer terms, processing information as it becomes available, rather
than storing for processing at a later time.
Record Buffer
Determines the length of the Time Delay clip that the record buffer loop
records on.
Resource
A resource is a Profile input, JPEG codec, or output. You allocate resources
for exclusive use by any application, such as Tool Box Editor, List Manager,
and VDRPanel. You should free up (deallocate) unneeded Profile resources
whenever possible to that they can be used by other applications.
RGB
An additive method of combining percentages of red, green, and blue
primary colors to form other colors.
ROM
See Read-Only Memory.
