CIMM DEFINITION: A coding system applied to digital content that manages the usage rights of that content. In order to present the content, the rights specified must be honored by the presenting device. This requirement is usually enforced by attaching the digital rights management (DRM) to encrypted content and protecting the information required to decode the content with keys that can only be obtained by a device authenticated by the DRM.

DTTV abbr Digital Cable

July 24, 2012

CIMM DEFINITION: A generic term for cable television signal that is transmitted via digital encoding over a cable network. (Source: Definition currently under review by CableLabs)

See: Digital Cable

CIMM DEFINITION: Often considered the same as Digital Cable. An advancement in terrestrial analog television which has a land-based signal broadcast.

Duplicate Tuning Record

July 24, 2012

CIMM DEFINITION: A data condition in which a meter or reporting system provides an exact copy of a tuning record or event. (Source: Nielsen)

Duration

July 24, 2012

CIMM DEFINITION: The length of a particular event. In linear tuning statements, the duration is the contiguous time for which a particular channel was selected. (Source: Nielsen)

2: The total duration of seconds in a spot. Tuning duration record provided by the operator. (Source: Kantar Media Audiences)

Note – Due to channel change Latency, channel change gaps, and the uncertainty of event reporting times in a STB, all of which may vary from STB to STB and channel to channel, accurate measurement of duration on a STB requires time synchronization, collection of STB timing data, and appropriate editing rules. (Source: FourthWall Media)

See also: DVR

CIMM DEFINITION: DVR capability available through a Set-Top Box. Subscribers to the DVR service are able to record video that can be viewed at a later time either linearly or with trick play.

See also: Dwell Time

CIMM DEFINITION: An industry agreed upon standard (not yet in existence) minimum level of average seconds of tuning duration before a tuning event will be saved in STB memory and sent upstream for tabulation. (Source: TRA)

NOTE – There is a difference between a one second and a five, ten etc., second standard. How is surfing calculated below the sub five second level? How to agree upon the standard?

NOTE – TRA does not recommend any Dwell Time filtration when collecting tuning data.

Dwell Time

July 24, 2012

See also: Dwell Filtration Standard

CIMM DEFINITION: The amount of time a home or Set-Top Box spends on a channel – presumably viewing or interacting – with a piece of content such as a program, channel or network as indicated through the Set-Top Box.

2: The period of time that a user spends viewing a channel, estimated from the time between channel changes. The amount of time of a contiguous tuning event. (Source: Nielsen)

3: Dwell Time refers to the amount of time that the Set-Top Box must be tuned to a specific channel in order to report a viewing session. Set by Pay TV Operator. Once minimum Dwell Time had been reached, the viewing record is captured back to the initial second. (Source: Kantar Media Audiences)

4: Dwell Time is set by the software in the STB, and is controlled by the operator, not by Rentrak. Often for reasons of network bandwidth, operators tend to set Dwell Times at 5 or 20 seconds. From a pure data perspective, it would be best to have short Dwell Times, but operators are necessarily concerned about network loading. Fortunately, the viewing that is excluded by a 5- or even 20-second Dwell Time is negligible in terms of total hours and average audience. (Source: Rentrak)

5: TRA uses at least eleven seconds. TRA recommends zero Dwell Time Filtration. TRA data suppliers use zero in one case and at least eleven seconds in the other case and TRA algorithms make the data consistent by estimating what is going on during the filtered gaps. (Source: TRA)

6: FourthWall Media collects all events, irrespective of Dwell Time, on all advanced and legacy Set-Top Boxes. Dwell Filtration Standards may be applied after the fact to the collected data, if needed. (Source: FourthWall Media)

NOTE – What is considered acceptable Dwell Time and what constitutes Latency?

NOTE – Nielsen uses the term “Dwell Times” to describe tuning event intervals. Dwell Times are impacted by “Latency”. Kantar Media Audiences says that Dwell Times are set by the Middleware. Kantar Media Audiences’ Middleware delivers in ten second increments (for Charter) and five seconds (for Direct) but delivers second-by-second data going back to the first second if there is viewing. Gaps of ten seconds are called surfing.

NOTE – No Dwell Time filtration for TIVO, every second is measured and counted.
