3. A Unified Approach to Delivering Content on Demand
With Client Independence
• E- note is end user customized content
• E-note consists of multimedia content
• E-note contents can be accessed by clients with varying capabilities
• E-note content accessed by a client is client dependent
• E-note is content creation on demand
• E-note content does not reside in one physical location
• E-note allows for more efficient use of network bandwidth
• E-note creation and delivery is transparent to the user and network
• E-note is a next generation service
• E-Note allows the end user to interact with the application
responsible for content
E-Notes is not a Unified Messaging Service

and customizes E-note using

E-note interaction interface
dependent on device
• Regular phone = Voice
• Terminal = Web Browser
• PDA = PDA based Browser
• Wireless PDA / Phone =
Client running on the device
Once E-note content has been
specified, the E-note is created
and delivered to the end-user in
a format compatible with the
client running on the access
device when the end user access
the E-note

7. An example creation of an E-Note on Monday
End user Bob decides his agenda
for the day :
• Check on kids at school
• Sell Imedia.com at $100
• Listen to Wall-Street Analyst
conference at 2:30 pm
• Receive fax from London
• Send document to Jim
• Call Gautam at 4pm
Bob uses the access
device Available to him
to create E-Note and sets
Preferences for E-note
E-Note is created and the content consists
of the following :
• Images from the classroom camera at school
• Alert to be generated for Bob when Imedia
stock price hits $100
• Alert that the Wall street Analyst conference
is on at 2:30 pm
• Alert that Fax from London has been received
• Alert to send document to Jim
• Alert to call Gautam at 4pm
E-Note is not a Unified Messaging
System !

listen to it on his terminal ( media player )
listen to it on his phone ( work or home )
listen to it on his wireless phone

11. From the two scenarios explained
Several things have to happen for the E-note to work
Since The user can set delivery preferences and content preferences:
1 - The client and the access device on which the client runs are connected to a
particular network. The information requested is going to be generated in
the
format the client on the accessing device understands and this is
encapsulated
into the protocols particular to the network the device is connected to.
2 - The content required to create the E-note can reside in applications anywhere
in the network the device is connected to or another network to which the
device may not be connected to. If the content resides on the network the
device is connected to then the task of creating the E-note is easier.
3 - The client running on the device accessing the content in the E-note may not
understand the native format of the content. For example in a netcast or
webcast the content might be in real format or wav file etc. If this is being
accessed from a device that has a client that does not have the capability to
understand this format then a translation might be done to enable content
delivery ( e.g. Text to speech, Midi to plain sound, Real format to text or

• The end user needs to access content provided by applications that sit on different networks
• Accessing applications on the edge of the same access networks is also a problem
• Content / applications that sit across diverse networks need complex protocol conversion
• Accessing applications across different networks adds traffic overhead
• Traffic demands may be too high if the end user wants to access true multimedia content
• No QoS guarantees can be given for the distributed applications
• The ASP model is inherently flawed as it would require one to build large data-centers and processing
centers to host and deliver applications

The big picture : How does E-notes fit in ?
• Imedia gateway will be a true gateway
• Imedia gateway will reside in the access network
• Imedia gateway will be an integrated software and hardware solution
• Imedia gateway is what makes e-notes possible
• Imedia gateway allows service providers to offer a real service over the bit pipe !
• Imedia gateway allows the creation of a virtual ASP that provides on-demand
content to the end user
• E-note does not physically reside anywhere in the network
• The dynamic nature of this solution allows for the most efficient utilization of
network bandwidth
