Profile PRO Series
Audio I/O
The audio path through the Profile video disk recorder, especially the
crosspoint circuitry that routes the audio within the Profile system.
Auto Start
A feature that lets you enter a timecode and have the record buffer start
recording at that timecode.
Bit rate
The rate at which video streams in megabits per second (Mb/sec). The bit
rate is a reflection of quality—the higher the bit rate, the higher the quality
of video. However, video data stored at a high bit rate consumes more disk
storage space than data stored at a lower rate. Bit rates can be as low as 6
Mb/sec and as high as 54 Mb/sec. The default video quality bit rate is 24
Mb/sec, which is broadcast quality.
BNC
Connector used in professional A/V components. The BNC connection
provides optimum shielding between the video input signal lines to provide
the best possible performance. BNC was recently adopted as an alternate
AES signal connector.
B Picture
A B picture is a bidirectionally 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 B picture relies on data from both forward and backward motion
vectors to determine how a future frame will be composed. See GOP,
I-frame, P Picture.
Button (on the display)
A small display box that has a raised appearance and contains text.
Generally, clicking on a button activates a function or performs some action.
See Clicking.
Button (on the mouse)
The two or three buttons on the top of the mouse.
