CIMM DEFINITION: A computer network that spans a relatively small area. Most LANs are confined to a single building or group of buildings, however, one LAN can be connected to other LANs over any distance via telephone lines and radio waves. (Source: http://www.webopedia.com)

2: A group of computers connected together (a network) at one physical location. (Source: IAB)

CIMM DEFINITION: An IMU size. (Source: IAB)

NOTE – The IAB‘s voluntary guidelines include seven Interactive Marketing Unit (IMU) ad formats; two vertical units and five large rectangular units.

CIMM DEFINITION: The lag time that occurs in the physical distribution plant and some STBs when the box changes channels or uploads so that tuning event timing relative to the same content can occur in one home at a slightly different time than in another home. Can be as much as several seconds.

2: According to TIVO there are several types of Latency: 1. signal distribution Latency where there is a lag in transmission of the signal to the box, 2. channel change Latency which is the time between channel changes and 3. remote Latency when the remote is pressed and the action is logged. Stress loads on the Set-Top Box may impact length of Latency and logging. (Source: TIVO)

3: The amount of time it takes for content to appear on the TV screen once distributed by the Set-Top Box. The lag time that occurs in some boxes when the box changes channels or uploads, or clock slippage. Can be as much as several seconds. (Source: Nielsen)

4: The time it takes for a data packet to move across a network connection. (Source: IAB)

5: The visible delay between request and display of content and ad. (Source: IAB(

NOTE – How is this viewing ascribed, if at all? The standard here appears to be at 5 seconds but this could vary based on the operator and their platforms.

NOTE – Lag time as the box changes channels or uploads. From Weisler Mediapost article there is a comment from John Grono, GAP Research, Sydney Australia)

“I would also like to caution analysis of data at the second-by-second level. There is considerable ‘drift’ in STB clocks, and of more importance there are Latency delays in broadcasts across platforms. Here in Australia on fiber-optic cable that Latency is around 8 seconds (the mode). Eight seconds out in a 15-second ad is an eternity! I would recommend some sort of content matching rather than time-based matching if this is an ongoing objective.”

NOTE – Channel change Latency can be affected by the Set-Top Box type, the middleware and resident application running on the Set-Top Box, the encoding of the channel being tuned to (e.g., HD, standard definition digital, analog, encrypted, non-encrypted), and the connection between Set-Top Box and TV (e.g., HDMI, RF, S-Video). Thus, Set-Top Box timing synchronization and editing rules for channel change gaps must be applied for each Set-Top Box individually.

NOTE – Second-by-second measurement is possible if the collection engine on the STB performs time synchronization and measures and collects Latency-related STB timing data, and collection servers apply appropriate editing rules. All times are then synchronized to the content times as they appear in the As Run Logs, regardless of the various distribution and STB latencies. (Source: FourthWall Media)

NOTE – Latency sometimes leads to the user leaving the site prior to the opportunity to see. In streaming media, latency can create stream degradation if it causes the packets, which must be received and played in order, to arrive out of order. (Source: IAB)

CIMM DEFINITION: Mobile data service related to an end user‘s immediate location. Examples include store or service locators and friend finders. (Source: IAB)

CIMM DEFINITION: Also known as a projection panel. A flat panel display, electronic visual display, or video display used in hardware such as computer monitors and television sets. LCDs use the light modulating properties of liquid crystals (LCs) that change reflectively but do not emit light directly.

CIMM DEFINITION: A lead is created when a prospective consumer in an iTV enabled Household (iTVHH) shows interest in a product or service by interacting with the asset or application on the television screen, by which authorizing the content owner to follow-up with the consumer with the offer. A lead is not a conversion, but could be the first step to conversion where applicable. (Source: CTAM Advanced Cable Solutions Consortium, itv Metrics)

CIMM DEFINITION: The number of leads that are generated from a single interactive application.

CIMM DEFINITION: Fees advertisers pay to Internet advertising companies that refer qualified purchase inquiries (e.g., auto dealers which pay a fee in exchange for receiving a qualified purchase inquiry online) or provide consumer information (demographic, contact, and behavioral) where the consumer opts into being contacted by a marketer (email, postal, telephone, fax). These processes are priced on a performance basis (e.g., cost-per-action, -lead or -inquiry), and can include user applications (e.g., for a credit card), surveys, contests (e.g., sweepstakes) or registrations. (Source: IAB)

CIMM DEFINITION: The flow of audience (as a percentage) from one program (or video or other content) into another that follows sequentially.

2: The percent of Set-Top Boxes  that were tuned to the program during its first 90 seconds who were also tuned to at least 90 seconds of the previous program. (Source: Kantar Media Audiences)

NOTE – Different Latency and editing rules for each processor lead to vastly different results.
