To limit the amount of transmitted data.
A component program object that can be used with web pages or other application programs. The technology for creating ActiveX control is part of software developed by Microsoft.
Abbreviation for Domain Name System server. As an IP address required for connecting to the device on an IP network is numerical and difficult to remember, the Domain Name System was established. A domain name is alphabetic and is easier to remember. When a client computer uses a domain name to connect to another computer, it asks a DNS server to translate the name into the corresponding IP address. Then the client computer can obtain the IP address of the computer to be connected.
Java Virtual Machine
Software that transfers the Java applet's byte code to the native code of your system to execute it.
The class D IP address assigned between 126.96.36.199 and 188.8.131.52. Using this IP address enables you to transmit the same data to multiple equipment.
The difference in tone between the lightest and darkest portions of the image.
A network address that uniquely identifies each LAN card.
Abbreviation for Internet Protocol Address. An individual IP address is basically assigned to each piece of equipment connected to the Internet.
Device that can be used to access the other network.
Abbreviation for Moving Picture Experts Group4. One of the MPEG standards for image compression format aiming to transmit images at a high compression rate with lower picture quality.
Software/hardware for coding/decoding video and audio data.
Software to be used for accessing the FTP server.
A server to be used to transfer files via a network.
One of the image compression formats. The standard written by the JVT (Joint Video Team) , joint organization for standardization composed of ISO and ITU-T. H.264 is capable of transmitting video data at a higher compression rate than that of MPEG4.
Secondary DNS Server
Subsidiary DNS server used when a primary DNS server cannot be used.
A port used to communicate between the web server and the web client such as a web browser.
Abbreviation for Dynamic Host Configuration Protocol server. The IP address of a terminal without an individual IP address can be automatically distributed by the Dynamic Host Configuration Protocol (DHCP). The DHCP server assigns the IP addresses to the terminals.
The rate at which data bits are transmitted.
To display the audio and video digital data from the video equipment on a computer.
Abbreviation for Joint Photographic Expert Group. The still image compression technology or standards of the ISO (International Organization for Standardization) and ITU-T. Popularly used as image compression format on the Internet, etc.
The portion that identifies the local network (subnet) in an IP address.
Bit rate that can be used for networking.
The number of frames of a moving image that can be transmitted per a second.
Zooming in/out function of an image without using an optical zooming function.
Network time server that transmits and receives time information over the networks.
The mode whereby a client FTP allows TCP connection for data transmission to the FTP server.
A server for storing incoming e-mail until you have read it.
Primary DNS server
One of the DNS servers that can first reply to a request by connected devices or other DNS servers.
A server or software that acts as an intermediary between a local network and the Internet so that it can connect to the Internet in place of a computer on a local network.
The degree to which the color is pure.
A program written in Java language that can be used in the web browser.
The degree to which the boundary of two portions is clearly distinguished.
A server for sending or relaying e-mail messages between servers.
A protocol for monitoring and managing network devices.
32-bit stream used to decide how many upper bits will be used for the network address within the IP address so as to distinguish the network.
Any content that is not a DCI/Hollywood movie that a digital cinema may wish to show e.g. HD, live concert/sports event, cult TV
Image of 4096 x 2160 pixels giving 8.8 million pixels per colour (four times the resolution of 2K)
A special lens used on 2K D-cinema projectors to stretch the image from an aspect ratio of 2:1 out to Cinemascope at 2.39:1. These lenses are no longer allowed to be used for Hollywood content under the new DCI specification.
Advanced Encryption Standard. 128-bit encryption is used under the DCI specification (not to be confused with Audio Engineering Society, the standards body for audio)
A visual presentation system that attempts to maintain or recreate moving images in the third dimension,
American National Standards Institute method of measuring projector brightness. The DCI specification favours "Foot Lamberts" (fL) measurement.
Proprietary Link Encryption technology CineLink is being upgraded to "CineLink II"
The final movie film print made directly from the cut film negative. It represents the "Master" from which all copies are taken. The aim of D-cinema is to bring this Answer Print quality into every cinema instead of the current poor film multi-generation copy quality

Composition Playlist (CPL)
A text file that contains all of the information on how the files for a specific Composition should be played back, including how the audio and subtitles are synchronized with the picture. The CPL could contain one reel or many reels, and there are different CPLs for each soundtrack or version that would play back. The CPL is created by the Digital Cinema Packaging Facility
A single element used for a DCinema presentation - ex: a feature or a trailer or an advertisement. A composition contains everything required for a successful screening of the content. This usually includes image, audio, subtitles, and a Composition Playlist (see picture on cover)
Composition Playlist (used in TMS) Content Element (used in SMS)
These phrases both refer to the pieces of content of the same type (ie. Trailers, Advertisements) that go towards making up parts of a Show Playlist
Captions (subtitles including cues and sound effects) that are not visible on the screen. Closed captions are seen using a closed caption device and only visible to these audience members. Text content is provided on the DCP.
Picture format with an aspect ratio of 2.39:1. Under the DCI specifications, all projectors must letterbox their imaging chips (which are about 2:1 aspect ratio) to show cinemascope movies. This means that a 2K projector vertical resolution goes down to just 700 pixels which is less than HDTV However, a 4K projector vertical resolution will be 1,400 pixels in cinemascope which is still 1 1/2 times the vertical resolution of HDTV keeping cinema ahead of home entertainment
