CIMM DEFINITION: A paywall that allows minimal to no access to content without a subscription.

CIMM DEFINITION: The process of taking disparate data sets for different constituencies and blending them so as to be able to exchange and share results to all constituencies from one database. To form a uniform language for future dialog.

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)

2: The uncompressed audio and video digital connection standard that enables high definition.

CIMM DEFINITION: A type of DSL that Transmits 2 Mbps bi-directional signals over one or two twisted copper pairs. HDSL is used in applications such as corporate Internetworking, video conferencing, and remote data center access. (Source: itvt.com/glossary)

NOTE – Often referred to as High Bit Rate Digital Subscriber Line.

CIMM DEFINITION: A television display technology that provides picture quality greater than that of traditional Standard Definition (SD) and digital sound similar to that of compact discs. (Source: Nielsen)

2: There are at least 18 different formats, but the ones most commonly in use are 1080i and 720p. CEA has established an icon which is used on HD monitors.  Consistent language is critical here as well as differentiating between true HD and other formats.

3: HDMI also allows STBs the ability to begin logging when television sets are on or off. (Source: TIVO)

4: A higher quality signal resolution using a digital format for the transmission and reception of TV signals. HDTV provides about five times more picture information (picture elements or pixels) than conventional television, creating clarity, wider aspect ratio, and digital quality sound.

NOTE – HD vs. SD measurement

NOTE – There are three definitions for HD content:  “Native HD” – refers to content filmed in HD, and does NOT apply to converted material; “True HD” — refers to content that is shot and mastered in HD, but may also apply to some converted material; and “HD” which applies to any kind of HD programming, including all converted content.

CIMM DEFINITION: The control center of a cable television system, where incoming signals are amplified, converted, processed and combined into a common cable along with any original cablecasting, for transmission to subscribers. The system usually includes antennas, preamplifiers, frequency converters, demodulators, modulators, processors and other related equipment. Or the central location on the cable network that is responsible for injecting broadcast video and other signals in the downstream direction. (Source: CableLabs)

2: The closest distribution point where a cable operator transmits content to their subscribers.

3: The electronic control center of a cable television system- generally located at the antenna site of CATV system. The headend takes incoming signals and amplifies, converts, processes, and combines them into a common coaxial or optical cable for transmission to cable subscribers. (Source: itvt.com/glossary)

4: The site in a cable system or broadband coaxial network where the programming originates and the distribution network starts. Signals are usually received off the air from satellites, microwave relays, or fiber-optic cables at the head end for distribution. (Source: IAB)

CIMM DEFINITION: Systematic recurring reporting event used by engineers to tell if a Set-Top Box is functioning. The absence of a heartbeat record indicates that there is a problem with the box. (Source: Nielsen)

NOTE – Would this type of signal quality measurement help measure STBs that do not have backchannel?

NOTE – Not all STBs use Heartbeat Records. (Source: TIVO)
