NCast Presentation Recorder Reference Manual
S-Video – A video connector (usually DIN style) where luminance and chroma information
are transmitted on separate wires or cable pairs. Provides for a higher fidelity image than
a composite connection.
SDI – Serial Digital Interface, a coax based standard for digital video signal interchange.
SDP – Session Description Protocol, for describing streaming media transmissions
SIF - Describes an image or display surface with a resolution of 320x240 pixels.
SVGA – Describes an image or display surface with a resolution of 800x600 pixels.
SXGA – Describes an image or display surface with a resolution of 1280x1024 pixels.
The aspect ratio for SXGA is 5:4. Support for a 4:3 aspect ratio is accomplished by
utilizing a 1280×960 subset of the display surface.
Telnet – An IP network based protocol, which was originally used to connect remote
consoles and terminals to mainframes, but is now used as a general, bi-directional, byte
oriented communications facility. See RFC’s 854 and 855.
Unicast – Refers to a point-to-point connection between two Internet host machines.
UXGA – Describes an image or display surface with a resolution of 1600x1200 pixels.
VGA – Describes an image or display surface with a resolution of 640x480 pixels.
WUXGA - Describes an image or display surface with a resolution of 1920x1200 pixels.
WXGA – Describes an image or display surface with a resolution of 1366x768 pixels.
Some projectors use WXGA to refer to 1280x720 as well. This display size implements a
16:9 aspect ratio, as compared to a normal 4:3 monitor.
XGA – Describes an image or display surface with a resolution of 1024x768 pixels.
