What is IPTV?

Basic IPTV:

>Standard Def. Television (SDTV)

>High Def. Television (HDTV)

>Local programming

>Video-on-Demand (VOD)

>Interactive program guide

>Music channels

>PVR

• 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

5

Integrating services with Television

• It is possible to integrate a number of services directly with the Television content, such as:• Telephony services

• Advertisement

• Emergency alert

• Web services

• Interactive Voting

6

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 year

2009.

• 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 provides

DRM (Digital Rights Management).

13

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.

14

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.

• 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

21

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.

22

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. 1280:720pand 1920:1080i are typically accepted as high-definition scan rates.

23

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.

24

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.

25

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

26

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.

27

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

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 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."

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
