Heavy Carrier

See also: Carrier, Light Carrier, Common Carrier

CIMM DEFINITION: A facilities-based carrier, that is, one that owns the switching and transmission systems that comprise the network it uses to provide services to its customers.

Heavy Lifting

July 24, 2012

See also: Demodualization

CIMM DEFINITION: The process of turning an analog signal into a digital signal. This is what occurs on the receiving end of a transported signal. Heavy Lifting separates the constant carrier signal from the variable data signals. This is part of what a Modem does. Video and audio streams must be de-multiplexed before they are decoded (Source: itvdictionary.com)

Heuristic

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)

CIMM DEFINITION: A local cable TV or telephone distribution network. An HFC consists of fiber optic trunks ending at neighborhood nodes, with coaxial cable feeders and drop lines downstream of the nodes. (Source: itvt.com/glossary)

HH abbr Household

CIMM DEFINITION: Defined as the subscriber and his / her co-habitants at a single physical address where video service is being delivered. (Source: IAB)

2: An individual who has contracted with a MVPD to receive cable services. (Source: CTAM Advanced Cable Solutions Consortium, DAI Metrics)

Highly Targeted Networks

CIMM DEFINITION: A Rentrak term for Long Tail Channels which are smaller, often unmeasured-by-Nielsen networks. (Source: Rentrak)

History List

CIMM DEFINITION: A menu in a web browser which displays recently visited sites. The same mechanism makes it possible for servers to track where a browser was before visiting a particular site. (Source: IAB)

Hit

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.

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)

NOTE – Typically, it welcomes visitors and introduces the purpose of the site, or the organization sponsoring it, and then provides links to other pages within the site. (Source: IAB)

Hops

July 24, 2012

CIMM DEFINITION: The excursion of a radio wave the earth to the ionosphere and back to the Earth. The number of hops indicates the number of reflections from the ionosphere. (Source: Wikipedia.org)

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)
