4 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 4 Basic IPTV: >Standard Def. Television (SDTV) >High Def. Television (HDTV) >Local programming >Video-on-Demand (VOD) >Interactive program guide >Music channels >PVR

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 5

6 How big will the IPTV market be? The worldwide IPTV Service Revenue is forecasted to reach U.S $38 billion in the year The worldwide IPTV subscribers are forecasted to reach 53 million in the year 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. 6

7 Triple/Quadruple play is the key concept Television services Data (Internet Access) Voice (Telephony) Mobile 7

8 Key Differences Between IPTV and Internet Video IPTV Internet Video Nature of Content Continuous streams of content Discrete content segments Content Selection Content Format Delivery network Hundreds of programming channels One or two formats are selected by the provider Private IP network Millions of content files Dozens of formats with multiple players Public Internet Viewing Device Consumer TV via Set Top Box Consumer PC display or portable device 8

9 How IPTV works? Your Television has never been such smart before! 9

10 IPTV System elements Element Description Video Content Paid to content suppliers such as broadcast networks Delivery Network Set Top Box Cost of IP network, part common equipment, part per subscriber Often rented, sometimes purchased by consumers Digital Head End Receives video signals converts into proper IP format Content Servers Used for on demand and advertising Electronic Program Guide May be produced locally by IPTV provider or acquired from a supplier 10

11 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 RTSP IGMP 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

12 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

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. 13

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. 14

15 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) 15

19 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 19

20 Aspect Ratio :3 16:9 All analog television standards use 4:3 aspect ratio 20

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. 21

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. 1280:720p and 1920:1080i are typically accepted as high-definition scan rates. 22

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 Mpbs of bandwidth. 23

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. 24

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 screen 1920 pixels x 1080 lines x 24 bits (3 x 8) x 30 frames/sec = Gbps 25

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 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

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. 27

42 42 What is Agile

43 Beginning with the Agile Manifesto Official definition from the Agile Manifesto lives here: "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

44 Waterfall Do we really understand the requirements upfront? Do we really understand where we are? Churn impacts quality and timeliness Agile Frequent customer input and feedback leads us where we need to go 44 Discovery and Customer Input From each Sprint

45 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 45
