IPTV (Internet Protocol Television) describes a system where a digital television
service is delivered to subscribers using the Internet Protocol over a managed
broadband connection.
Beyond Broadcast TV & Films (Cable/Satellite/Terrestrial),in terms of its interactive real-time control and material selectivity
Beyond Video Download over the Internet,
which is not necessarily real-time
Beyond Best Effort Video calls over the Internet,
which is without quality controlled

How big will the IPTV market be?
The worldwide IPTV Service Revenue is forecasted to reach U.S $38 billion in the
year 2009.
The worldwide IPTV subscribers are forecasted to reach 53 million in the year2009.
The Americas and Western Europe are expected to be the biggest markets in
terms of revenue per user basis.
China will be the future IPTV dragon due to rapid urbanization, fast growing
economy and expanding middle class.

IP Unicast versus IP Multicast IP Unicast is the way how Internet currently works.
It is point to point
Consumes huge amount of bandwidth/resource for multimedia applications
IP Multicast is the way how IPTV network delivers video content.
It is point to multi-point
Consumes less bandwidth/resource, since streams are replicated
on the network rather then server.

Pieces. What builds up the IPTV puzzle?
A number of components operate together in a such manner that
provides end to end video solution:
Content feeds Video content (Analog or Digital).
Encoders/transcoders Encodes/transcodes the input into a format
suitable for IP delivery(Mpeg-2/H.264).
Encrypters
Secures the content and providesDRM (Digital Rights Management).

STB (Set Top Box)
The consumer device connected to Internet, Gets the content stream, decodes the content
and sends it up to the Television,
Provides user interaction with the Television,
Stores recorded content if has PVR(Personal Video Recorder) capability.

Digital TV
Total image resolution displayed in DTV and HDTV is referred to in terms of number of pixels
on the screen rather than lines.
The four vertical scan line systems used in digital TVare:
480p (480 lines vertically scanned in a progressive fashion),
720p (720 lines vertically scanned in a progressive fashion),
1080i (1,080 lines scanned in an interlaced fashion).
1080p (1,080 lines scanned in an progressive fashion)
Standard Definition Television (SDTV) refers to digital transmissions over
480-line resolution, either interlaced or progressive scanned formats.

HDTV
High-Definition Television (HDTV) is the high-resolution
subset of our DTV system. 16:9 image with twice the horizontal and vertical resolution
of our existing system, accompanied by 5.1 channels of DolbyDigital audio.
HDTV generally defines, an image with 720 progressive or1080 interlaced active (top to bottom) scan lines. 1280:720pand 1920:1080i are typically accepted as high-definition scan
rates.

Standard Definition (SD) vs. High Definition (HD)
An MPEG-2 SD video transmission can range 3-6 Mbps
depending on the type of content.
This same content transmitted using HD resolutions willneed from 12-20 Mpbs of bandwidth.

Access Networks and High Definition
ADSL can deliver up to 8Mbps of bandwidth but not providesufficient bandwidth for HD content.
ADSL2 can deliver 11Mbps which is roughly sufficient for asingle HD stream.
ADSL2+ can support a theoretical maximum of 24Mbps of
multiple HD streams.
VDSL, a costly alternative, is able to provide 52Mbps.
Fiber, with its 100Mbps, provides a complete solution for the
delivery of multiple HD contents to the subscriber's home.

Why to compress the content?
SDTV (NTSC):
Standard screen
640 pixels x 480 lines x 24 bits (3 x 8) x 30 frames/sec = 221
Mbps
HDTV:
Large screen1920 pixels x 1080 lines x 24 bits (3 x 8) x 30 frames/sec =
1.493 Gbps

Mpeg-2
MPEG-2, published as a standard in 1994, is a high-bandwidth encoding
standard, supporting a bandwidth range of approximately 2Mbps to more than20 Mbps.
MPEG-2 Was expanded to encompass HDTV requirements at app. 12-20
Mbps.
MPEG-2, a lossy video compression algorithm, compresses video data atratios of 70:1 to 100:1 depending on the type of content being compressed.
Now the required bandwidth for video transmission is roughly 4Mbps for
SDTV and 12 to 20 Mbps for HDTV.

H.264 (Mpeg-4 Part 10)
Recently, we are witnessed the emergence of MPEG-4 (the
H.264 flavor), an improved compression algorithm adopted bythe broadcasting industry providing video quality similar toMPEG-2 at roughly one half the bit rate.
MPEG-4 arose from a need to have a scalable standard
supporting a wide bandwidth range from streaming video at

What is Agile
5/26/2018 IPTV Presentation V2

43
Beginning with the Agile Manifesto
Official definition from the Agile Manifesto lives here: www.agilemanifesto.org
"We are uncovering better ways of developing software by doing it and helpingothers do it. Through this work we have come to value:
Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan
That is, while there is value in the items on the right,we value items on the left more."

Why Agile?
- speaks directly to the bottom line
Predictability Easier to manage project scope, predict TTM, fewerbig late and bad
Shorter iterations, Continuous Integration, Continuous Feedback Customer Appeal Clear measure of progress
Story based requirements, More opportunity for customer involvementto suggest feedback and innovation
Quality Done-done at the end of each Sprint
Tests match the actual usage, less to test per iteration, clear ownership
Maintainability Clear business requirements and incentive to keepdesign simple
Prioritized list, constant integration, more cycles to eliminate potentialproblems
