What is IPTV?
• 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
Basic IPTV:
>Standard Def. Television (SDTV)
>High Def. Television (HDTV)
>Local programming
>Video-on-Demand (VOD)
>Interactive program guide
>Music channels
>PVR

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
IGMP
RTSP
MPEG Transport Stream
• 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.
11
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 provides
DRM (Digital Rights Management).
12
Pieces. What builds up the IPTV puzzle?
(Cont’d)
• VoD (Video On Demand) Servers
• Stores on demand video content and sends to interested parties.
• EPG (Electronic Program Guide) Provider
• Provides easy to navigate/programmable
TV Guides.
• Middleware
• This core component stores:
• Subscriber data,
• Channel information,
• EPG data,
• STB (Set Top Box) information.
• Provides communication between
other building blocks.
13
Pieces. What builds up the IPTV puzzle?
(Cont’d)
• 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.
• DHCP(Dynamic Host Configuration Protocol)Server
• Distributes the IP addresses to STBs,
• Sends the video head end connection
information to STBs.
14
IPTV brings telephony services
to Television World
• Caller ID - Name/Number Display
• Call Logs
• Caller ID w/ Picture
• Address book
• Call Disposition
• SMS/MMS Text Messaging
• Click to Call (C2C)
• Message Waiting Indication (MWI)

Painting the screen
• Scanning Method
• Interlaced (i): Odd lines refreshed on first pass,
even lines on next pass
• Each pass is called a “field”
• Progressive (p): Entire screen refreshed in
order
• Refresh Rate
• Number of times per second that screen image
is fully replaced
• Generally determined by power source

16:9
• All analog television standards use 4:3 aspect ratio
20
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 TV are:
• 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.
21
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 Dolby
Digital audio.
• HDTV generally defines, an image with 720 progressive or
1080 interlaced active (top to bottom) scan lines. 1280:720p
and 1920:1080i are typically accepted as high-definition scan
rates.
22
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 will
need from 12-20 Mpbs of bandwidth.
23
Access Networks and High Definition
• ADSL can deliver up to 8Mbps of bandwidth but not provide
sufficient bandwidth for HD content.
• ADSL2 can deliver 11Mbps which is roughly sufficient for a
single 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.
24
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 screen
1920 pixels x 1080 lines x 24 bits (3 x 8) x 30 frames/sec =
1.493 Gbps
25
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 than
20 Mbps.
• MPEG-2 Was expanded to encompass HDTV requirements at app. 12-20
Mbps.
• MPEG-2, a lossy video compression algorithm, compresses video data at
ratios 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.
26
H.264 (Mpeg-4 Part 10)
• Recently, we are witnessed the emergence of MPEG-4 (the
H.264 flavor), an improved compression algorithm adopted by
the broadcasting industry providing video quality similar to
MPEG-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 <64
Kbps, suitable for Internet applications, to app. 4 Mbps for
higher-bandwidth video needs.

What is Agile
42
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 helping
others 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."
43
Waterfall
Do we really
understand the
requirements upfront?
Churn impacts quality
and timeliness
Do we really
understand
where we are?
Agile
Frequent customer
input and feedback
leads us where we need
to go
44
Discovery and
Customer Input
From each Sprint
Why Agile?
- speaks directly to the bottom line
• Predictability …Easier to manage project scope, predict TTM, fewer
‘big late and bad’
• Shorter iterations, Continuous Integration, Continuous Feedback
• Customer Appeal …Clear measure of progress
• Story based requirements, More opportunity for customer involvement
to 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 keep
design simple
• Prioritized list, constant integration, more cycles to eliminate potential
problems
