Analysis week 10 post
IPTV networks
An IPTV network essentially consists of three fundamental components: a content aggregation segment, a content distribution segment and a consumption device.
Aggregation takes place at a super headend where programming is collected from multiple sources: off air, fiber networks and satellite feeds. This content is encoded and multiplexed into an MPEG transport stream, IP encapsulated, L-band modulated and then uplinked to a satellite.
AVC or VC-1 codecs maximize transponder bandwidth efficiency. This can also eliminate transcoding farther downstream. AVC/VC-1 compressed video is IP encapsulated and multiplexed in an MPEG transport stream. Using this methodology, content can be delivered to the customer's premise and decoded by the STB or PC.
IPTV system operators build regional headends where additional content is received. This content can arrive from a satellite, off air or over landlines. In the IPTV network operations center, EPG information is generated, content is encrypted and conditional access and DRM control is implemented by middleware. Customer service and billing systems are integrated into the content management system layer.
Delivery to the customer continues over telco or cable broadband systems to a local DSLAM (Digital Subscriber Line-Access Multiplexer), and then the last mile to an IPTV STB or media PC that completes the system. The MPEG-IP packets are transported as UDP (User Datagram Protocol) packets using RTSP (Real-Time Streaming Protocol.)

1,700 customers on UniFi, up to RM300 million allocated for TM’s IPTV
RM300 million is not much especially when compared to what ASTRO and Media Prima are spending, but it is a good start for TM. Some RM250 million to RM300 million has been allocated for TM’s IPTV service which is part of its HSBB(UniFi) offerings.
“The spending will depend on opportunities. We are very careful on the acquisition of content; it has to match the business per se. We must also ensure that our service is also attractive enough for our customers. It’s more of a balance rather than an aggressive one in terms of content offering for our customers,” TM’s CEO told Theedge.
TM currently offers 22 channels via its IPTV service. According to the same news report, TM has signed up over 1,700 customers while another 10,000 have registered their interest and waiting for the service installation.

3G Codecs and IPTV
IPTV is the delivery of television over a closed broadband IP distribution network to consumers. And no matter how you look at it, lower bit rates save bandwidth, which increases channel offerings and maximizes the bottom line. Because of this, 3G video codecs are a perfect match for IP-based digital TV.
With compressed data rates half that of MPEG-2, third generation (3G) video codecs make IPTV possible. VDSL and ADSL2+ broadband networks stream content at upward of 25Mb/s.
The last-mile access network requires fiber-optic system upgrades. One of two methods is typically used. FTTP (fiber-to-the-premises) runs fiber-optic cable to the customer's equipment. FTTN (fiber-to-the-node), in lieu of upgrading every connection to a customer, uses optical cable to the distribution point (pole or box) and then uses copper wire to reach the customer's home.
Regardless of which method is used, end-to-end IPTV service solutions with encoding, encapsulation, third-party middleware, scrambling/descrambling, satellite receivers, conditional access, set-top boxes (STBs), service management and integration services require a large financial investment. Aggregation and distribution of content is heavily dependent on satellite networks; therefore, large players dominate the field and are joining together to deliver turnkey infrastructures.
Real-world numbers of IPTV
So, how has IPTV fared in real-world deployment? The numbers are cloudy because the service is just taking off.
AT&T U-verse rosily predicted passing 18 million homes, but faced a reality check when the envisioned number was reduced to 8 million. Some sources state that AT&T's Q4 report cited 3,000 subscribers.
The largest IPTV implementation so far is in Hong Kong, where PCCW claims 650,000 subscribers. During the next five years, IPTV is expected to grow to 80 million subscribers worldwide from about 6 million IPTV households today.
IPTV Future
Interactivity is a given with IPTV and may be the application that captures consumer attention. All the technological pieces are in place. Perhaps the time is finally right for the long-awaited convergence of the PC and TV.
Traditional OTA broadcasters are in a winning position. IP distribution of DTV programming is yet another distribution channel that, properly managed, can produce additional revenue. Whether this is an opportunity or problem depends on one's personal viewpoint.

IPTV in Malay
IPTV adalah saluran-multi, televisyen Internet Protocol, kandungan high-definition yang lebih penghantaran selesa. Sebaliknya, isyarat yang dihantar melalui satelit, kabel atau laluan terestrial, IPTV isyarat disebarkan melalui jalur broadband. Hal ini membantu pelanggan untuk menonton, seperti telefon bimbit atau permainan rangkaian dalam permainan video PC, atau bentuk lain yang serasi media. Statistik terbaru tentang IPTV, Multimedia Research Group, sebuah trend yang kuat untuk teknologi. Pada tahun 2008, IPTV sebenarnya pengguna, beberapa lebih dari 100 juta untuk menutup pada akhir ramalan, akhir tahun 2008, atau 21,3 juta, sehingga diperkirakan 26,9 juta pengguna pada tahun 2009, lebih dari 810.000 yuan, 2013.

History of IPTV
In 1994, ABC's World News Now was the first television show to be broadcast over the Internet, using the CU-SeeMe videoconferencing software.
The term IPTV first appeared in 1995 with the founding of Precept Software by Judith Estrin and Bill Carrico. Precept designed and built an Internet video product named IP/TV. IP/TV was an MBONE compatible Windows and Unix-based application that moved single and multi-source audio/video traffic, ranging from low to DVD quality, using both unicast and IP multicast Real-time Transport Protocol RTP and Real time control protocol RTCP. The software was written primarily by Steve Casner, Karl Auerbach, and Cha Chee Kuan. Precept was acquired by Cisco Systems in 1998. Cisco retains the IP/TV trademark.
Internet radio company AudioNet started the first continuous live webcasts with content from WFAA-TV in January, 1998 and KCTU-LP on January 10, 1998.
Kingston Communications, a regional telecommunications operator in UK, launched KIT Kingston Interactive Television, an IPTV over DSL broadband interactive TV service in September 1999 after conducting various TV and VoD trials. The operator added additional VoD service in October 2001 with Yes TV, a VoD content provider. Kingston was one of the first companies in the world to introduce IPTV and IP VoD over ADSL.
In 1999, NBTel now known as Bell Aliant was the first to commercially deploy Internet Protocol Television over digital subscriber line DSL in Canada using the Alcatel 7350 DSLAM and middleware created by iMagic TV owned by NBTel's parent company Bruncor. The service was marketed under the brand VibeVision in New Brunswick, and later expanded into Nova Scotia in early 2000 after the formation of Aliant. iMagic TV was later sold to Alcatel.
In 2002, Sasktel was the second in Canada to commercially deploy Internet Protocol IP video over digital subscriber line DSL, using the Lucent StingerR DSL platform. In 2006, it was the first North American company to offer HDTV channels over an IPTV service
In 2005, Bredbandsbolaget launched its IPTV service as the first service provider in Sweden. As of January 2009, they are not the biggest supplier any longer; TeliaSonera who launched their service later has now more customers.
In 2006, AT&T launched its U-Verse IPTV service in the United States, comprising a national head end and regional video-serving offices. AT&T offered over 300 channels in 11 cities with more to be added in 2007 and beyond. In March 2009, AT&T announced that U-verse had expanded to 100 or more High Definition channels in every U-Verse TV market. While using IP protocols, AT&T has built a private IP network exclusively for video transport.

Disadvantages of IPTV
Packet Loss
IPTV uses the same technology that other types of data use to send and receive information (Internet Protocol). Due to this fact, your TV may experience from time to time a pack loss or delays. Your experience can be significantly worse if your IPTV connection is not up to par or not quick enough.
Currently No Support for HDTV
Most of the IPTV systems currently do not support HDTV broadcasts. However, technology is improving and since this is an important issue most analysis state that this will be corrected in the near future.
