F
Field
In interlaced video, a part of the image frame that is scanned separately. A field is a collection of either all the odd lines or all the
even lines within the frame.
Frame
One of the many still images displayed in a sequence to create a moving picture. A frame is made of horizontal lines of pixels. For
example, a 1920x1080 frame consists of 1080 lines, each containing 1920 pixels. In analog video frames are scanned one at a time
(progressive scanning) or split into fields for each field to be scanned separately (interlaced video).
Frame rate
The number of frames shown per second (fps). In TV and video, a frame rate is the rate at which the display device scans the
screen to "draw" the frame.
Frame rate multiplication
To stop low frame rate 3D images from flickering, frame rate multiplication can be used, which increases the displayed frame rate
by two or three times.
G
Gamma
A nonlinear operation used to code and decode luminance. It originates from the Cathode Ray Tube technology used in legacy
television sets.
Ghosting
An artifact in 3D image viewing. Ghosting occurs when an image intended for one eye is partially seen by the other eye. Ghosting
can be removed by optimizing the dark time and sync delay.
H
HDCP (High-bandwidth Digital Content Protection)
An encryption scheme used to protect video content.
HDTV (High Definition Television)
A television system with a higher resolution than SDTV and EDTV. It can be transmitted in various formats, notably 1080p and
720p.
