See also: Anonymization, De-Identify

CIMM DEFINITION: The result of anonymizing MAC addresses or other identifying information about the household or Set-Top Box. Results in a STB identifier per each data record that cannot be matched back to the original household, viewer or Set-Top Box.

NOTE – In some cases hashing is carried out daily which destroys ability to do Reach / Frequency / Frequency Distribution / ROI reporting because there is no persistent anonymous household identifier in those cases. (Source:TRA)

CIMM DEFINITION: A technology that protects high value digital content such as films and television programs against unauthorized access or copying between a set-top box or DVR and a digital TV or computer.

CIMM DEFINITION: A specification that combines video and audio into a single digital interface for use with DVD players, digital television (DTV) players, Set-Top Boxes, and other audiovisual devices. The basis for HDMI is High Bandwidth Digital Content Protection (HDCP) and the core technology of Digital Visual Interface (DVI). HDCP is an Intel specification used to protect digital content transmitted and received by DVI-compliant displays. (Source: CableLabs)

July 24, 2012

CIMM DEFINITION: A way to measure a user’s unique identity. (Source: IAB)

NOTE – This measure uses deduction or inference based on a rule or algorithm which is valid for that server. For example, the combination of IP address and user agent can be used to identify a user in some cases. If a server receives a new request from the same client within 30 minutes, it is inferred that a new request comes from the same user and the time since the last page request was spent viewing the last page. Also referred to as an inference. (Source: IAB)

July 24, 2012

CIMM DEFINITION: The point at which users access a Web site and their computer sends a request to the site’s server to begin downloading a page. (Source: IAB)

NOTE – Each element of a requested page (including graphics, text, and interactive items) is recorded by the site’s Web server log file as a “hit.” If a page containing two graphics is accessed by a user, those hits will be recorded once for the page itself and once for each of the graphics. Webmasters use hits to measure their servers’ workload. Because page designs and visit patterns vary from site to site, the number of hits bears no relationship to the number of pages downloaded, and is therefore a poor guide for traffic measurement. (Source: IAB)

Home Page

July 24, 2012

CIMM DEFINITION: The page designated as the main point of entry of a Web site (or main page) or the starting point when a browser first connects to the Internet. (Source: IAB)

2: A similar excursion from an earth station to a communications satellite to another station, counted similarly except that if the return trip is not by satellite, then it’s only a half hop. (Source: Wikipedia.org)

3: A waveform transmitted for the duration of each relocation of the carrier frequency of a Frequency-hopping spread spectrum system. (Source: Wikipedia.org)

4: To modify a modulated waveform with constant center frequency so that it frequency hops. (Source: Wikipedia.org)

5: With routing a distance in terms of topology and of a length that may be not specified topographically, i.e. one hop is the step from one router to the next, on the path of a packet on any communications network (on the Internet often discovered with pings or traceroutes). The hop count then is the number of subsequent steps along the path from source to sink. The term “hop” can be seen in some networking based courses referred as “Hand Over Point” in routing terminology. (Source: Wikipedia.org)

HSD abbr High Speed Data

July 24, 2012

CIMM DEFINITION: Data that originate from broadband sources.

CIMM DEFINITION: Those consumers who have highly changeable purchasing patterns of behavior within a specific product category in which they buy heavily, indicating low brand loyalty in that category, and who have a propensity to sometimes switch brands, be motivated by advertising and marketing messages or other sales related messages or inducements.

2 . A term coined by TRA which is a combination of two consumer purchasing categorizations – heavy overall category purchase combined with occasional purchasers of the specific brand.

3: Heavy category purchasers who have bought a brand before, are the HSPs for that brand. For most mature packaged goods brands, HSPs are the ROI Driving Target for television advertising ROI. The reason is because advertising is a “light tap” that rarely causes someone who has never bought a mature CPG brand before, to suddenly buy it; instead, TV advertising does most of its incremental sales generation for mature CPG brands by getting homes that have already made it into a brand’s consideration set i.e. they have bought the brand before, to buy more of it than they would without advertising. HSPs are not simply ardent brand switchers. HSPs are specific to each brand, there is no such thing as e.g. soft drink HSPs or facial tissue HSPs i.e. HSPs are not a category level phenomenon but they are instead a brand level phenomenon. (Source: TRA, registered term)

CIMM DEFINITION: The standard for exchanging files (text, graphics, and multimedia) on the World Wide Web. Or HTTP is the transport layer for HTML documents over the Internet Protocol (IP). (Source: CableLabs)

2: A server application that establishes a secure, encrypted connection to a server or web browser.

3: HTTP is the protocol that client and server computers use to transmit information over a bi-directional connection without interfering with each other. Typically, every HTTP transaction consists of a “request” for a specific file, web page, or other content sent from the client to the server, followed by a matching “response” from server back to client containing the requested content. HTTP is also the mechanism for EBIF applications to communicate with servers. (Source: FourthWall Media)
