Own TV Set.
Vote and Give Your Opinion.
Many TV watchers can easily pause live programming,
record shows or skip through TV advertisements. On
some programs such as a documentary, there might be
layers of information that a viewer might be able to
access with just a click of the remote. Many cable and
satellite companies already include DVR's (digital video
recorders) that can digitally store programming, so that
you can pause your show, watch shows from different
angles or skip through commercials.
Another common feature that is making its way into the
interactive TV market is the ability to purchase products
and services via your TV set. Today, you can easily
purchase a pay per view program with the click of the
remote, but very soon, you might be able to watch a TV
commercial and instantly purchase and pay for the product
being advertised with just one click.
The ability to vote or cast your opinion via the TV set.
Many television programming asks viewers to
participate live with their show. This might be in the
form of voting for a favorite entertainer, voting in a
news poll or giving your opinion on a new show.

• Interactive Voice Response - is a technology that automates
interactions with telephone callers.
• Interactive Voice Response (IVR) systems allow callers to
interact with your communications system over the telephone.
• IVR is used to enable the caller to retrieve information from a
database, enter information into a database, or both. IVR
systems allow you to efficiently exchange information,
reducing clerical processing.
• Enterprises are increasingly turning to IVR to reduce the cost
of common sales, service, collections, inquiry and support
calls to and from their company.
• Historically, IVR solutions have used pre-recorded voice
prompts and menus to present information and options to
callers, and touch-tone telephone keypad entry to gather
• Modern IVR solutions also enable input and responses to be
gathered via spoken words with voice recognition.
An IVR system talks to callers following a recorded script. It
prompts a response and waits for the caller to respond either
verbally or by pressing a touchtone key, and supplies the
caller with information based on responses made.
IMPORTANT FEATURES OF IVR SYSTEM
IVR system should store responses made by callers.
Should be able to provide different responses to callers based
on time of day called.

When a customer dials some short code using his mobile
number, the call flows via MSC / Switch and it is routed to
the respective operator servers through PSTN.
The MSC first checks the mobile number of the incoming call
accordingly routes the call to the respective operators.
It also checks whether the incoming short code is configured
in the MSC or not; if not then it will send “Connection Error
Message” to the customer.
The operator checks the short codes in the incoming call, and
routes the call to the appropriate servers. There are number of
servers like WiFi Network server, Cerebrum, On Mobile etc,
these servers contains different short codes, depending on the
dialed short code the operator passes the call to the
appropriate server (WiFi server). From the WiFi server the
call goes to the WiFi desktop, from this point the customer
starts communicating with the recorded voice (i.e. IVRS). In
this a customer hears a Welcome Note, Language selection

operator will then check the short code and accordingly it will
forward the call to the respective server in which the short
