9. General requirements for Digital
Media Services -2
 The Multiple measurable parameters such as frame
rate , resolutions ,colors and data rate are mainly
used to quantify the quality of digital media services ,
which are called as quality characteristics .
 Those above parameters are also treated as 4-
standard DMS quality characteristics .
 Other quantifiable characteristics may consider for
rich digital media services .
 The rich digital media service includes the high
resolution data intensive scientific visualization .

15. High Resolution visualization in
science-1
 The scientific visualization needs –high speed large
volume optical transport and high quality digital media
services .
 It requires 2-steps implementations
 Step-1. Design the network for scientific
visualization
- In order to design and operate the optical network for
scientific visualization application , a set of system
management process is required to provide device
locations ,resource balancing and communication
management .
- It also requires multiple components , processes and
timing among processes .

16. High Resolution visualization in
Science -2
 Step-2.Do experiment with reach digital
media in HPDMN Global network
environment .
- HPDMN-high performance digital media network .
- It’s a global large scale distributed environment that
has designed and implemented to support large scale
scientific visualization .
- It uses open source scalable adaptive graphics
environment (SAGE) system to support visualization.
- SAGE is a technology for visualization of multiple high
definitions video streams in MISHRA screen .

19. High quality real time consumer video
application over optical n/w-2
 Now to describe the optical network services for high
quality consumer media applications, it is required to
focus the different optical networks with related
consumer media applications .
 OBS-optical burst switching
-good service for digital cinema applications.
- Support bulk data transfer .
- Achieve better capacity utilization and a high degree
of statistical multiplexing ,while implementing in media
applications .
-Combines merits of optical circuit switching (OCS) &

20. High quality real time consumer video
application over optical n/w- 3
 WDM-wavelength division multiplexing
- Multiple wavelengths are multiplexed into a single
fiber
- Support high bandwidth for video transmission
- Best suited for static network connections
 OTDM-optical time division multiplexing
- Creation of optical multiplexed stream at significant
speed .
- Able to encode high definition image at 3D screen
- Capable to encode multiple streams and transferred
with multiple paths .
- Multiple video sources-------multiple media consumers

21. High quality real time consumer video
application over optical n/w-4
 OPS- optical packet switching
-provides high bandwidth and fine granularity
-but OPS systems are very difficult to implement
because practical optical buffer are not yet available .
Last discussion – moving media contents closer to users

23. High quality real time consumer video
application over optical n/w-6
 The delivery of real time multimedia contents consists
of 3-primary functions
 Media productions /compositions
 Adaptions
 Delivery /Distributions
 When the multimedia contents need to be delivered to
multiple end devices , it mainly requires adaptions to
different format .

25. Conclusion & Research Issue
 From the discussion we conclude that a successful
digital world can be made through the effective
integration of optical network technologies and digital
media services .
 Due to the involvement of multiple components and
processes in high resolution scientific visualization-
the resource balancing is a problem .
 Effective development of multidimensional multi
streaming multipath optical network transportation
with an optimal traffic load is a challenge in optical
networked digital media applications .
