2. Digital Cinema - Digital Cinema captures, distributes, and projects motion
pictures using digital technology.
HD - High-definition television (HDTV) provides a resolution that is substantially
higher than that of standard-definition television.
2K - a Digital Cinema picture that is 2048 pixels wide by 1080 pixels high -‐
6.67% more pixels than a consumer high definition TV picture, which is 1920
pixels wide by 1080 pixels high.
4K – a Digital Cinema picture with four times the number of pixels of 2K: 4096
wide by 2160 high. The 4K different is visible, especially to viewers toward the
front of the auditorium and especially with stadium seating.
DCP (Digital Cinema Package) – A DCP is a set of files containing the
picture, sound, subtitles and metadata that are the result of the
encoding, encryption and packaging process. This is the format that the
majority of digital cinemas require. DCP often refers to the media containing
the set of files, which is distributed the theatres.

3. Aspect Ratio – the displayed width divided by the displayed height of a specific
image. Most common Digital Cinema aspect ratios are;
- 2.35:1 (Scope) – wider, more panoramic aspect ratio.
- 1.85:1 (Flat) – used typically for lower budget projects, trailers and
ads.
- 1.77 (16/9) – used most often for television and DVD content. Also
known as wide/full screen.
Resolution - Resolution is a measure used to describe the sharpness and clarity
of an image or picture and is often used as a metric for judging the quality of
monitors, printers, digital images and a various other hardware and software
technologies. It also helps to distinguish the visual quality of movies and to
distinguish between high definition and standard definition movies.
3D Film - A 3D or 3-D (three-dimensional) film is a motion picture that enhances
the illusion of depth perception. Derived from stereoscopic photography, a
regular motion picture camera system is used to record the images as seen
from two perspectives (or computer-generated imagery generates the two
perspectives in post-production), and special projection hardware and/or
eyewear are used to provide the illusion of depth when viewing the film.
4D Film - 4D film or 4-D film is a marketing term for an entertainment
presentation system combining a 3D film with physical effects that occur in
the theatre in synchronization with the film. For example, movement of the
chair.
