image quality. This communication takes place over the DDC
–
Display Data Channel.

“Frame”: In interlaced video, a frame is one complete picture. A video
frame is made up of two fields, or two sets of interlaced lines. In a film,
a frame is one still picture of a series that makes up a motion picture.

“HDMI” - High – Definition Multimedia Interface: An interface used
primarily in consumer electronics for the transmission of
uncompressed high definition video, up to 8 channels of audio, and
control signals, over a single cable. HDMI is the de facto standard for
HDTV displays, Blu-ray Disc players, and other HDTV electronics.
Introduced in 2003, the HDMI specification has gone through several
revisions.

“HDSDI”: The high-definition version of SDI specified in SMPTE-292M.
This signal standard transmits audio and video with 10 bit depth and
4:2:2 color quantization over a single coaxial cable with a data rate of
1.485 Gbit/second. Multiple video resolutions exist including
progressive 1280x720 and interlaced 1920x1080 resolutions. Up to 32
audio signals are carried in the ancillary data.

“JPEG” (Joint photographic Expects Group): Commonly used
method of loss compression for photographic images using a discreet
cosine transfer function. The degree of compression can be adjusted,
allowing a selectable tradeoff between storage size and image quality.
JPEG typically achieves 10:1 compression with little perceptible loss
in image quality. Produces blocking artifacts.
 “MPEG”: Motion Picture Expect Group. A standard committee under
the auspices of the International Standards Organization working on
algorithm standards that allows digital compression, storage and
transmission of moving image information such as motion video,
CD-quality audio, and control data at CD-ROM bandwidth. The MPEG
algorithm provides inter-frame compression of video images and can
have an effective compression rate of 100:1 to 200:1.

“NTSC”: The color video standard used in North America and some
other parts of the world created by the National Television Standards
Committee in the 1950s. A color signal must be compatible with
black-and-white TV sets. NTSC utilizes an interlaced video signals,
525 lines of resolution with a refresh rate of 60 fields per second (60
Hz). Each frame is comprised of two fields of 262.5 lines each, running
at an effective rate of 30 frames per second.
