devices, etc. VOD allows viewers to select video and its
content, then have it sent for viewing to their set-top

stored in the customer’s DVR.

and Internet distribution scenarios.) Or, in the case of
cable television and IPTV,
the customer typically can watch it directly
from the network's head-end

distribution and storage facility). (See Network

TV-based Video on Demand has come a long way, and fast. Up until
literally the last few years, many in the television world would
readily categorize it as "Interactive Television". But as it has
developed the industry ended up separating it from Interactive
Television by giving it it's own category. There is no doubt that it is
a form of Interactive Television but at a "lower level". Earlier this
decade a significant number of TV-based VOD systems required the
subscriber to call the network operator with their programming and time
of viewing choices.
Cable and telco networks, due to having larger bandwidth capacity than
most satellite TV providers, are currently in a better position to
offer Video on Demand for television, as well as Network
Digital Video Recording (nDVR). Telcos are incorporating IPTV

are restricting the
number of titles available for VOD for fear of programming being
copied, as well as a perceived lack of profit. Movie studios generally
won't allow movies to be available through VOD until 45 days after the
DVDs go on sale. At the time of this writing (spring, 2006,) studios
typically earn only $1 or $2 from each movie rental but can make $12 or
more from each DVD sale.
VOD advertising is often sold on a cost-per-impression basis. The
problem with doing business based on impressions is that programmers
arrive at the count in different ways. An impression could mean an ad
has been viewed in its entirety or only in part.
TV-based Video on Demand is often available in these formats:
1) Free VOD, which includes Basic or Family Packages.
2) Subscription VOD, where a separate regularly re-occurring fee is
charged for a plurality of VOD programming. (Examples are Showtime
and HBO On Demand
3) Pay-per-view VOD, (Transactional VOD), often used to deliver
individualized programs on demand. With PPV VOD, often the customer can
watch all he/she wants in a 24 hour period. Special boxing matches are

content provider (most likely your network operator) offers a function,
service and/or program that no other content provider has (or very few
have), it might be called Exclusive Video on Demand.

makes available as part of a basic content package.

be Subscriber Video on Demand (SVOD) where a subscriber pays a standard
reoccurring fee for programming that may have no, or limited

– This is the opposite of Subscription Video on Demand
With Transactional VOD the customer pays for each individual video on
demand program. With it's opposite, SVOD, typically the subscriber pays
a set amount, (often monthly) for a set amount of video on demand.
Now-a-days most refer to Transactional
VOD simply as "VOD".
Video On Demand
- (TVOD) - (Now just known as Video on Demand) - An older antiquated
term for video on demand (VOD) service where individual end-users would
get immediate responses when interacting with the Video on Demand
system. With TVOD, the user would order the program at will and be able
to do VCR-like commands on the VOD system with the same quick response
time as when operating a VCR. This increased speed of the response time
can significantly increase the cost of operating a VOD system. An
alternative was Near Video on Demand (NVOD) as it reduced the cost by
increasing the waiting time. TVOD is more often just known as VOD
(Video on Demand) as it is the standard form of VOD in television now.
Two major types of VOD are streaming video and
non-streaming video. Streaming video (sometimes known as HTTP Streaming
video or Progressive
) is when the video is compressed and sent
network, such as the Internet. It’s then decompressed by the
receiver (set-top box) for displaying on your screen. Typically the
file begins displaying before it has completely been delivered to your set-top
(to save transmission time and bandwidth.) Literally the
programming plays as it's being downloaded. The non-streaming
variety of video needs the downloaded files to be completely sent
before they can be played.

of video and serving it (sending it) to user's TV systems. Also
important is the Conditional

system) where the broadcaster controls the subscriber's access to
digital and Interactive TV services. This can ensure that the
person is who he/she says they are (authenticity) and provides security
for purchasing and other transactions. The end-users
(subscribers) have a receiver (set-top box) that allows him or her "Conditional

(or the equivalent) may be used to access the system by the end-user.
TV-based Video on
Demand is revolutionizing the television viewing experience. Why?
Because in time you'll be able to view most of your favorite
programming (shows) in this manner, and not just movies and/or special
events. Imagine at any time of the day or night, searching
interactively through your TV and finding your favorite sit-coms listed
by episode. Click interactively on an episode’s electronic button, in
the same manner that you would on a Web page and up comes what that
episode is about and other pertinent information about it. Want to
watch 10 episodes in a row of that sit-com, even if it’s midnight? No
problem, you make your own viewing schedule with Video on Demand.
(Chances are good you'll need a digital TV package).
One of the major reasons for
implementation of VOD
is to cut down on “Churn.” Churn denotes subscribers that start and
stop their subscription faster than the network would prefer, a process
that adds to the business cost of networks. The assumption is that if
more options are available for the customer, they will be less likely
to stop receiving the service.
Developments such as improvements in VOD servers, better codecs
better ethernet, and Passive
(PON) etc. technologies replacing the older,
slower technologies such as asynchronous serial interface (ASIs)
connections, have been essential.
Marketplace, which launched in November of 2006, as of mid-2007, has
around 2,100 hours of movie downloads available to Xbox 360 owners.
It's introduction to Europe is set for August, 2007. (Of course we all
know about iTunes' success as a download service.)
