GLOSSARY OF TERMS
Digital Rights Management: A class of
technologies used by publishers, copyright
holders, and media enterprises with the intent
to control the use of digital content and devices
after sale. (See Licensing)
Encoder: Software or hardware that turns a
video source into a format that a distribution
method (such as CDN) or end-user player can
HTTP Streaming: Video delivery method using
HTTP encapsulation. Examples include HTTP
Live Streaming (HLS), H T TP Dynamic Streaming
(HDS), and Dynamic Adaptive Streaming over
H T TP (MPEG-DASH). These technologies are
specifically built to deliver video. Many content
providers are moving to these methods because
of lower costs and higher quality.
Licensing: Licensing is a commercial agreement
on how the content can be distributed and who
can view it, usually at a geographic country level.
This licensing can determine how much security
a broadcaster will need for that asset. Most
content that is created by studios is licensed.
Companies protect licensed content with Digital
Rights Management (DRM) schemes.
Live: Video delivered directly to the end user
from the source, such as a video camera pointed
at a performer.
Long-Form: Long-form video content lasting
over 15 minutes in length and usually high quality.
Feature films would be long-form content.
Long Tail: Content that is not very popular.
Unpopular content is very hard to cache as it is
not requested often. This means the likelihood
of content being in the cache is very low.
Metadata: Information about a video. Metadata
includes information on how long the asset is
available to end users, media duration, genre,
and other information. This is usually encoded
with the video and is stored to be used with the
CMS or digital asset management (DAM) system.
Paywall: A paywall is a system to securely
monetize digital content, such as pay-per-view.
Most media companies make money either
through advertising or through pay-per-view. A
paywall is typically a monthly subscription service.
Post-Roll: A video clip, such as a sponsorship
message, that is shown after the main content
Pre-Roll: A video clip, such as a sponsorship
message, shown before the main content is shown.
Progressive Download: The oldest form of
video delivery, usually used for smaller pieces
of content. The end user uses byte-range HT TP
requests to receive content.
Short-Form: Content that is very popular and
extremely cacheable because of the number of
requests it receives.
Simulcast: A simulcast is when an event is
broadcast and also streamed live to the Internet.
Tokenization: URL tokenization is the application
of a special token at the end of a URL string, for
This token authenticates the asset and user
to the server receiving the request. The token
usually specifies the right assignment, duration,
and validity of the request.
Tokens are commonly used to protect assets
from deep-linking. Tokenization is used by many
agencies and studios for a “good enough” level
of protection against misuse of content.
Transcoding or Transmuxing: Changing from
one format to another, usually done on the fly. Most
CDNs offer some form of transmuxing product.
True Streaming: As opposed to progressive
download, this method is analogous to broadcast
radio or television. It is expensive to use as it
requires specific server architectures. True
streaming is currently falling out of favor and
being replaced by HTTP streaming.
VOD: Video on demand, which is pre-recorded
content stored for future use.
