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 lost 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 allow 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.

“PAL”: Phase Alternate Line. A television standard in which the phase
of the color carrier is alternated from line to line. It takes four full
pictures (8 fields) for the color-to-horizontal phase relationship to
return to the reference point. This alternation helps cancel out phase
errors. For this reason, the hue control is not needed on a PAL TV set.
PAL, in many transmission forms, is widely used in Western Europe,
Australia, Africa, the Middle East, and Micronesia. PAL uses 625-line,
50-filed (25 fps) composite color transmission system.

“Operator”:
Refers to the person who uses the system.

“PIP”: Picture-in-Picture. A small picture within a larger picture created
by scaling down one of the images to make it smaller. Each picture
requires a separate video source such as a camera, VCR, or computer.
Other forms of PIP displays include Picture-by-Picture (PBP) and
Picture-with-Picture (PWP), which are commonly used with 16:9
aspect display devices. PBP and PWP image formats require a
