Advertising Targeting (Internet) The web allows adverts to be targeted primarily in three ways. 1 By web publication - which allows advertisers to target campaigns based on the simple level of the known demographics of a publication. 2 The choice of content within a web publication. This is particularly important in large online publications such as Electronic Telegraph, which may contain pockets of content targeted at certain groups - for example medical news pages being read by doctors and consumers interested in health issues. 3 Dynamically targeted adverts which deliver different adverts to different groups of readers while they are reading the same page. New software which is being adopted in 1997 by some of the main UK new media publishers is opening up the direct marketing potential of the web. There are two types of dynamic targeting. The first, and simplest, allows adverts to be targeted from information which is carried to the website by the users browser. Typically this will include the type of browser and computer, a generalised statement of what country they are reading from (unfortunately this is based on domain names and often fails) and information about which websites they have visited. The second method is only open to sites like the Telegraphs Electronic Telegraph which have a registered base of users for which they know certain characteristics. In theory an advert could be targeted based on any of the data captured in the questionnaire such as age, gender, occupation.

Bit Unit of measurement of data transmitted in digital form. Hence the measurement of the capacity of a cable system to carry information will be in terms of kilobits or megabits per second(Kbits/s,Mbits/s). (See also Bandwidth).
Bit Depth How precise an audio sample can be. Because of [science], higher bit rates have a wider difference between the quietest sound they can record, and the loudest sound, and therefore allow you to record at lower levels. 16-bit is CD quality, 24-bit is preferred for recording, 32-bit float theoretically never clips, but uses lots of disk space. See “Headroom.”
Bit Rate How much disk space is used per second of audio, which are measured in bits, even though everywhere else we measure files in bytes (8 bits = 1 byte). In compressed audio formats like mp3, the Bit Rate is the best number we have to gauge audio fidelity, because the compression scheme causes phrases like “sample rate” and “bit depth” to lose all meaning.
Bit rate The speed at which a digital file is transferred expressed in bits per second, eg 1 Bps. Bit rate is defined in video streaming to indicate interuption free viewing.
Bitrate/Bit rate Transmission speed expressed as the number of bits per second (b/s or bps), but more often expressed as multiples (e.g. 1 kbps = 1,000 bps; 1 Mbps = 1,000,000 bps; 1 Gbps = 1,000,000,000 bps). Bitrates denote the amount of information that can be transferred in a given time interval. Video applications are highly bitrate intensive. The required bitrates depend on a number of factors, such as desired picture quality, sampling rate of original material, compression algorithms, method of encoding, amount of information contained in the samples (e.g. very high for sports, lower for studio interviews). Typical present day requirements are 1Mbps for VHS, 5 Mbps for DVD and 15 Mbps for HDTV.

CRR The Contracts Rights Renewal (CRR) was put in place by the Competition Commission in 2003 following the merger of Carlton and Granada to form ITV plc. CRR is intended to protect the advertising market: a) by guaranteeing that advertisers and media buyers are no worse off following the merger of Carlton and Granada; and b)by putting in place an automatic ratchet which reduces the amount advertisers have to commit if ITVs audience shrinks. The CRR sets out a number of rights that advertisers and media buyers have when buying advertising time from Carlton/Granada, and in particular, gives advertisers and media buyers the right to renew their contracts on a rolling annual basis, adjusted for changes in ITVs audiences, with no reduction in the discounts they receive. Until the remedy is no longer necessary, the share of revenue committed by advertisers/media buyers on television advertising to Carlton/Granada need not increase above 2003 levels.

Dynamic advertising targeting Dynamically targeted adverts which deliver different adverts to different groups of readers while they are reading the same page. New software which is being adopted in 1997 by some of the main UK new media publishers is opening up the direct marketing potential of the web. There are two types of dynamic targeting. The first, and simplest, allows adverts to be targeted from information which is carried to the website by the users browser. Typically this will include the type of browser and computer, a generalised statement of what country they are reading from (unfortunately this is based on domain names and often fails) and information about which websites they have visited. The second method is only open to sites like the Telegraphs Electronic Telegraph which have a registered base of users for which they know certain characteristics. In theory an advert could be targeted based on any of the data captured in the questionnaire such as age, gender, occupation.

Effective/equivalent sample size Also termed equivalent, effective sample size denotes the estimated size of the sample based on sample error and after removing the effects of weights and dependencies within the sample caused by clustering (i.e. individuals within the same sample population living in the same household). In practice, measures of effective sample size are usually calculated by examining the effects of panel weights alone. For single audience measures, the effective sample will always be lower than the actual sample on the basis that, the greater the variability of panel weights within the selected sample/sub-sample, the lower the effective sample size.

GRP (Gross rating point) Unit of audience volume, which is based on the percentage of the target audience population that has viewed a transmission across a unit interval (usually minute by minute audience, but some TAM systems base their GRP estimates on the second by second audience). For example, a GRP of 10 implies an audience size that is equal to 10% of the audience being measured. Meanwhile the total GRP delivery of a schedule of advertising spots is equal to the sum of commercial GRPs/ratings across all the spots contained in the schedule. GRP totals or averages may be estimated for a wide range of different time periods, programme or commercial selections. For purposes of calculating commercial GRPs and making comparisons, commercial GRPs for each advertising spot are typically adjusted to a standard 30 second advertising spot interval.

HDTV (High definition television) Television broadcasting systems with notably higher resolution than conventional standard definition television (SDTV) systems. In order to achieve higher resolution HD broadcasts, a much greater bandwidth capacity is required, which has been facilitated by the development of digital compression technologies. The term is also relative. Three main factors define HDTV broadcast systems: (1) Vertical display resolution (mostly today 720 or 1080 lines, versus 525 in the American NTSC SD format, or 625 for the European PAL and SECAM formats); (2) Scanning system (progressive or interlaced); (3) Number of frames transmitted per second (from 24 to 60 Hz today, depending on the system). The actual quality of HD broadcast will depend on several factors, such as how well operators follow the technical specifications. The superior quality of HD over SD signal quality also becomes steadily more noticeable with larger screen sizes.

IPTV (Internet protocol television) This is a system where a digital TV service is delivered using Internet protocol over a network infrastructure, which may include delivery by a broadband connection. A general definition of IPTV is television content that, instead of being delivered through traditional broadcast and cable formats, is received by the viewer through the technologies used for computer networks. For residential users, IPTV is often provided in conjunction with VOD and may be bundled with Internet services such as Web access and VoIP. The commercial bundling of IPTV, VoIP and Internet access is referred to as "Triple Play" service (adding mobility is called "Quadruple Play"). IPTV is typically supplied by a service provider using a closed network infrastructure. This closed network approach is in competition with the delivery of TV content over the public Internet, called Internet Television. In businesses, IPTV may be used to deliver television content over corporate LANs.

P2P (Peer-to-peer) Peer-to-peer/P2P networks are the alternative to central server networks. Instead of all members feeding of a central server that responds to user requests, P2P networks use the connectivity between participants in the network to handle traffic, whereby requests are handled across the total pool of participants, each of whom contributes to the total computing power, storage space and bandwidth of the network. An important advantage is that the capacity of P2P networks increases as they add members. This is in sharp contrast to client-server networks, where additional customers will cause lower transfer speeds. For content distributors, the appeal of P2P networking is that it reduces central overheads. (see also File sharing)

Peoplemeter measurement General methodology for collecting TAM data by means of a household panel sample equipped with a dual metering system that registers (a) TV set status (i.e. which channel is being tuned to) and (b) viewer presence. Peoplemeter TAM research is currently restricted to measuring in-home audiences with meters attached to each TV set. Introduced commercially during the mid eighties, peoplemeter measurement now predominates over all other TAM methodologies throughout the world. Its key advantages for the advertising community are that it offers highly detailed (minute by minute or even second by second) continuous audience measurement for 24 hours a day and 365 days a year, and is impartial, being free from bias compared with the interview and diary-based recall methodologies.

Until a permanent change of channel is recorded, the meter will continue to record the most recent channel/set use as if no change(s) had taken place. This entails the assumption that consequent errors of attribution are balanced across channels.

Push VOD (Video on Demand) This is a technique used by a number of broadcasters on systems that lack the interactivity to provide true VOD, to simulate a true VOD system. A push VOD system uses a PVR to automatically record a selection of programming, often transmitted in spare capacity overnight. Users can then watch the downloaded programming at times of their choosing. As content occupies space on the PVR hard drive, downloaded content is usually deleted after a week to make way for new programmes.

QRS Quality Of Reading Survey is a major study which aims to give advertisers, agencies, and media owners a greater understanding of the value of print medium and the differences within it. The survey measures a wealth of behavioural and attitudinal characteristics among the readers of magazines and newspaper sections and supplements, including page exposures*** (PEX), time spent reading, number of pick-ups, how a publications is read, and a series of agree-disagree attitude statements. QRS is sponsored by the IPA, ISBA and PPA and conducted by RSL- Research Ltd. QRS research was conducted by face-to-face CAPI interviews in the home, on a total sample of just over 15,000 adults aged 15+. The interviews were conducted in two phases, October 1997 - January 1998 and October 1999 - May 2000 (QRS 2). There are no more surveys due to be carried out. The interview followed NRS methodology exactly, in measuring average issue readership of all publications and the key classification data. Readership data was collected for all national print titles featured on the NRS, creating a media list of more than 240 consumer magazines, newspaper sections and supplements. The study was carried out by IPSOS-RSL, which is the research company responsible for NRS. Click here for a list of QRS titles

Unlike the latter, sample bias cannot be calculated statistically, but can only be established empirically by comparing two or more samples with different known composition. Latent bias is often used to refer to potential unknown or hidden biases in the data which cannot be assessed.

Targeted Advertising The web allows adverts to be targeted primarily in three ways. 1 By web publication - which allows advertisers to target campaigns based on the simple level of the known demographics of a publication. 2 The choice of content within a web publication. This is particularly important in large online publications such as Electronic Telegraph, which may contain pockets of content targeted at certain groups - for example medical news pages being read by doctors and consumers interested in health issues. 3 Dynamically targeted adverts which deliver different adverts to different groups of readers while they are reading the same page. New software which is being adopted in 1997 by some of the main UK new media publishers is opening up the direct marketing potential of the web. There are two types of dynamic targeting. The first, and simplest, allows adverts to be targeted from information which is carried to the website by the users browser. Typically this will include the type of browser and computer, a generalised statement of what country they are reading from (unfortunately this is based on domain names and often fails) and information about which websites they have visited. The second method is only open to sites like the Telegraphs Electronic Telegraph which have a registered base of users for which they know certain characteristics. In theory an advert could be targeted based on any of the data captured in the questionnaire such as age, gender, occupation.
Targeted Advertising Addressable or Targetted Advertising is a type of advertising whereby advertisements are placed so as to reach consumers based on various traits such as demographics, purchase history, or observed behavior.

TVR Television Ratings - The TVR is the currency of the television industry, and measures the popularity of a programme, daypart or commercial break or advertisement, by comparing its audience to the population as a whole. For example, if Coronation Street achieved a Housewife TVR of 30 in Yorkshire, this means that 30% of all Housewives in the Yorkshire region watched an average minute of Coronation Street - while the other 70% either watched another channel or were not watching television at all. TVRs are calculated for each minute for all channels. Programmes, dayparts and commercial breaks, all of which are longer than one minute, take their TVRs from the average of the relevant minute TVRs. A commercial, usually shorter than a minute is assigned the TVR of the minute in which it started, unless it is weighted. Commercial campaigns are frequently assessed by totalling the TVRs of their individual spots (even though TVRs are percentages in origin).

UCR Under-colour removal - This technique is used particularly when the printing is to be by web-offset. Where a subject has a dark area, the four-colour process will normally reproduce this using large dots of all four colours, whereas an identical effect can be achieved using only one or two colours. When heavy dots of all four colours overprint each other, there are drying and other problems, and more ink is used than is necessary. To avoid this situation, the scanner can be set to remove most or all of the magenta and yellow in the dark areas, leaving mainly black, sometimes with some cyan to improve the density. The printer should inform the repro house of under-colour removal requirements before reproduction work starts.

' Expenditure or 30 second ratecard equivalent weighting is calculated by referring to regional ratecard costs of differing commercial lengths. For example, a 10 second commercial usually costs half as much as a 30 second commercial, so the 10 second will be given a weighting of 0.5.
