CIMM DEFINITION: A unique two letter top level domain that is assigned or used for a country or territory. Examples include: .uk for England and .jp for Japan.

CIMM DEFINITION: A communication channel access principle that employs spread-spectrum technology and a special coding scheme (where each transmitter is assigned a code).

2 : CDMA also refers to digital cellular telephony systems that use this multiple access scheme, as pioneered by QUALCOMM, and W-CDMA by the International Telecommunication Union (ITU), which is used in GSM’s UMTS.

3 : A digital cellular technology that uses spread-spectrum techniques. Unlike competing systems, such as GSM, that use TDMA, CDMA does not assign a specific frequency to each user. Instead, every channel uses the full available spectrum. Individual conversations are encoded with a pseudo-random digital sequence. CDMA consistently provides better capacity for voice and data communications than other commercial mobile technologies, allowing more subscribers to connect at any given time, and it is the common platform on which 3G technologies are built.

CIMM DEFINITION: An inter-relationed group of computers that function without a central server. This enables users to access data more efficiently and avoid bottlenecks. The data in a CDN can be anything from internet content, digital video, software, files, applications etc.

See also: Footprints

CIMM DEFINITION: Among boxes returning data, it is the complete number of Set-Top Boxes  or homes in a Cable, Satellite, Telco or other set-top data provider’s footprint. As opposed to a sample or panel which is a subsection of a population and not the entire population. In some cases, a census is whatever amount of homes or Set-Top Boxes  the data provider sends to the data processor.

2: According to Rentrak, a Census is every Set-Top Box in the house and/or every house that has service in the footprint.

3: A complete count of a population or universe. (Source: Nielsen)

4: The total number of Set-Top Boxes  or households collected in a given time frame, expressed by using the mean day’s count.. The key phrase is “boxes returning data.”  Not all systems / Set-Top Boxes return data on a regular basis. (Source: Kantar Media Audiences)

5: A complete count of every EBIF-capable Set-Top Box in the digital cable footprint or universe. (Source: FourthWall Media).

NOTE – Not always provided by the data processors, for various reasons. Definitions for Census vs. Footprint vs. Universe vs. Coverage Area vs. Population sometimes overlap.

CIMM DEFINITION: A telephone company facility where subscriber’s lines are joined to switching equipment. Competing service providers often “co-locate” their equipment within the incumbent telephone company’s facilities. (Source: Nielsen)

CIMM DEFINITION: CGI‘s are used to allow a user to pass data to a Web server, most commonly in a Web-based form. Specifically, CGI scripts are used with forms such as pull-down menus or text-entry areas with an accompanying submit button. The input from the form is processed by a program (the CGI script itself) on a remote Web server. (Source: IAB)

CIMM DEFINITION: A transmission path between two points. The term channel may refer to a one-way path or, when paths in the two directions of transmission are always associated, to a two-way path. It is usually the smallest subdivision of a transmission system by means of which a single type of communication service is provided, i.e. a voice channel, teletypewriter channel, or data channel. (Source: CableLabs)

2: A frequency band assigned by the FCC for AM, FM or TV transmission. Each broadcast television station is permitted to operate on only one channel. Channels are assigned geographically to minimize interference between stations. (Source: Nielsen)

3: A band of similar content. (Source: IAB)

4: A type of sales outlet (also known as channel of distribution), for example retail, catalogue, or e-commerce. (Source: IAB)

NOTE – Broadcast or Cable channel.

NOTE – A TV station may broadcast in both HD and SD. (Source: Invidi)

CIMM DEFINITION: The maximum number of channel spaces available on a specific television system, operator, satellite or Telco.

See also: Latency

CIMM DEFINITION: During a channel change, the period of time between the display of one channel and the next. Depending upon the Set-Top Box either a black screen, grey screen, still image, flickering, or some combination may be displayed during this time, which may last from a small fraction of a second to many seconds. During this time, the viewer typically has no control of the Set-Top Box, and all inputs from the Remote Control are ignored, or queued for later execution. Appropriate editing rules must account for these gaps when providing second-by-second metrics. (Source: FourthWall Media)

CIMM DEFINITION: The movement change from one network or channel to another via the use of a device such as a remote. Depending on the service or the Set-Top Box, there can be a lag time between channel changes (often called “Latency”) which can last several seconds.

NOTE – Latency in channel changes creates a challenge for standardization of measurement.
