HDTV (High-Definition
Television)
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.
Head end
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.
Heuristic
a way to measure a user's unique identity. 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.
History lists
a pull-down menu which displays the sites you've recently
visited so you can return to the site instantly or view
your latest session. The same mechanism makes it possible
for servers to track where you were before visiting a particular
site.
Hit
when users access a Web site, their computer sends a request
to the site's server to begin downloading a page. Each element
of a requested page (including graphics, text, 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
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. Typically, it welcomes you
and introduces the purpose of the site, or the organization
sponsoring it, and then provides links to other pages within
the site.
Host
any computer on a network that offers services or connectivity
to other computers on the network. A host has an IP address
associated with it.
Hotlists
pull-down or pop-up menus often displayed on browsers or
search engines that contain new or popular sites.
Hot spot
see Hyperlink.
House ads
ads for a product or service from the same company. “Revenues”
from house ads should not be included in reported revenues.
HTML (Hypertext Markup Language)
a set of codes called markup tags in a plain text (*.txt)
file that determine what information is retrieved and how
it is rendered by a browser. There are two kinds of markup
tags: anchor and format. Anchor tags determine what is retrieved,
and format tags determine how it is rendered.
HTML page
a HyperText Markup Language document stored in a directory
on a Web server and/or created dynamically at the time of
the request for the purpose of satisfying that request.
In addition to text, an HTML page may include graphics,
video, audio, and other files.
HTTP (Hyper-Text Transfer Protocol)
the format most commonly used to transfer documents on the
World Wide Web.
Hybrid pricing
pricing model which is based on a combination of a CPM pricing
model and a performance-based pricing model. See CPM pricing
model and performance-based pricing model.
Hyperlink
HTML programming which redirects the user to a new URL when
the individual clicks on hypertext.
Hypertext
text or graphical elements on a page which activates a hyperlink
when clicked.
