EXECUTIVE SUMMARY

This Report presents the details of IPTV (Internet Protocol Television). IPTV is creating the headlines around the world because of its humble deployment and its future. IPTV is an very useful system which provide TV, audio and video contents as well as other multimedia content. IPTV is not like any ordinary program broadcast over the internet, its unique in itself. Delivery of IP made via IP based secure channels. In this report I had discussed about How IPTV works, Its Implementation and Architecture and component of IPTV, QOS, Applications and benefits of IPTV as compared to other traditional TV methods.

INTRODUCTION

The Internet is changing the field of television broadcasting in much the same way it has changed and is changing other fields. Operating environments are opening up, access to the field is becoming easier, new business models are being born and old ones disappearing, services are becoming more globalized, and the customers’ position and freedom of action are improving. On the other hand, for the customer this signifies an increase in the data security risks related to television and a sense of uncontrollability and chaos – creating a counterpoint to the shared media experiences that used to bring the nation together.

The transfer of moving images in IP protocol-based networks has gradually become more common. Nowadays, video material of differing quality is available on the Internet and that material’s quality and usability in consumers’ terminal devices is dependent on the load placed on the transmission equipment and network, consumers’ connection speeds and the used terminal device’s capacity.

IPTV is a combination of voice, video, and data service. IPTV is all possible because of high availability of bandwidth and Internet access at very high speed nowadays. Because of low speed internet access in previous day’s idea of IPTV was impossible to implement.

Definition

Internet Protocol Television (IPTV) is a system by which internet television services are delivered using the Internet Protocol Suite over a packet-switched network infrastructure, e.g., the Internet and broadband Internet access networks, instead of being delivered through traditional radio frequency broadcast, satellite signal, and cable television (CATV) formats. We can also call it a process of sending television signals over IP data networks. These IP networks can be managed for example Digital Subscriber loop or they can be unmanaged example Broadband Internet. If the television signal is in analog the video and audio signals are first converted to a digital form. Packet routing information is then added to the digital video and voice signals so they can be routed through the Internet or data network

Internet TV is not an IPTV?

IPTV sometime confuses people and subscribers with Internet TV. Internet TV is quite different with the IPTV. Internet TV only allow its subscribers or users to watch movies, video and other multimedia content in best effort manner on the other hand IPTV provides security, end to end service management, Interactivity and quality of services to its user.

Why IPTV?

IPTV fulfil the demands of Subscribers or users in better way as users wants more and high quality video and audio content from content and TV providers. Other digital and analog TV have limited data transmission and limited channel capacity and one way transmission with no interactivity and control over what the subscriber want to view. IPTV overcome these drawbacks of traditional TV methods and provide enormous features and services to the customers.

Simple

IPTV allows easy navigation, quick program in formations, Picture in Picture and Pay Per view capabilities.

Personalized

You can personalize your view, profile, events, parental controls, and television and account settings. You can also attach your TV, Digital cam and other devices together.

Advanced

It provide live notifications such as email, SMS etc. while you watching TV. IPTV also provides many advanced features such as s/w based tuning, fast navigation, channel slide show, combined broadcast, VOD and DVR, features for program search etc.

IPTV’S impact

IPTV impact can be categorized into three areas:

Content – IPTV promises to make more content available, easy to access programs and content and it also provide portability.

Convergence –Applications can be run on multiple end-user devices

Interactive – IP network gives two ways interactivity between subscribers, content providers and service providers.

Summary

This chapter we have discussed introduction to IPTV, Its Definition, why we need IPTV and how it is different from the internet TV.

Working of IPTV

It is important to discuss the steps which are followed to convert the analog audio and voice signals into digital form before we get into the other details of IPTV configuration. There are various process and steps which are required to convert any analog signal into digital signal.

Digitization Process

Digitization is the conversion of analog audio and voice signal into digital signal followed by compression into the appropriate form. For any digital TV including IPTV this is the first step. Digitization can be performed by following given steps.

Sampling

Sampling is the conversion or reduction of continuous wave signal to a discrete value signal. A sample refers to a value or set of values at a point in time and/or space.

Figure 2.1 Sampling

Quantization

Quantization is the process of mapping a large set of input values to a smaller set of values.

Figure 2.2 Quantized Signal

2.1.3 Encoding

Encoding is the assignment of the binary values to the quantized samples.

Why Convert Analog to Digital

We convert Analog signals into digital ones because they analog signals are susceptible to noise and distortion and cannot be able to travel for long distances.

Whereas Digital signal are more resistant to noise and can travel for long distance without distorted then analog..

Figure 2.3 Audio digitization

Figure 2.4 Video digitization

2.3 Digital Media Compression

Using this technique we convert the higher speed digital signals which are the actual signals into lower speed digital signals. It provide low data transmission rate than normal digital video signals but provide good quality audio content and video content.

2.4 Sending and Managing Packets

It involves Packets routing from the network and managing of the packets loss when packet doesn’t reach the destination. Routing of packets is done based up on the source and destination address. These addresses determine the path through which the packet travels.

2.5 Television Gateways

It transforms the video and audio content received from media server or television signal source in format viewed by different viewers and different types of networks.

Figure 2.5 IPTV Gateways[HAR2006]

Above diagram shows that how gateway converting audio, video and other control information into a format which is sent through the internet.

2.6 Types of Transmission

Transmission of IP television channel can be unicast in which the data is directly delivered to specific viewer or customer and can be multicast copy of the data is sent to multiple persons at same time.

Unicast

Unicast transmission is the providing data to single client in a network. In unicast users connect to the streaming server which sends completely separated streams to every user. Diagram below shows the traditional unicast technology there is the same data stream on different parts of the network. It uses more network resources such as bandwidth, nodes and loads the servers heavily.

Figure 2.7 IPTV Unicast Transmissions

Multicast

Multicasting provides the data transfer and communication between user created groups. Through multicasting single message is sent to many users who are the part of the group so it can be viewed as a one to many deliveries. It Require less bandwidth and other network resources

Figure 2.8 Multicast Transmissions

Summary

This chapter discuss the working of IPTV. First we have discussed about digitization which is the process of converting analog signal into digital signal. Then we discussed about the steps needed for the digitization that is sampling, quantization and encoding. AT last this chapter also give the overview of multicasting and unicasting which are important in the functioning of IPTV.

IPTV Architecture and Protocols

The IPTV architecture consists of the following functional components

Content Sources: Its function is to receive video content from producers and other sources. And then these contents are encoded and store in acquisition database for VoD.

Service Nodes: It receives video streams in different formats and communicates with the customer premises equipment and home networking for the session with subscriber and Right management of digital data, service nodes communicate with the IPTV service. 

Wide Area Distribution Networks: It is made up of distribution capability, capacity, and quality of service. It contain core and access networks and also consists of other features , such as multicasting , which is require for the reliable and on time of IPTV data signals or contents from the service nodes to the CPE. It can be present at central office or Remote Distribution Centre. 

Customer Side Access Links: This is the last mile link between the customer premises and Wide Area Distribution network. It can be a High speed DSL technology such as VDSL AND ADSL. This also can be a fiber link to provide FTTH( Fiber to Home Access).

Customer Premises Equipment (CPE): CPE is present at customer location. This is the network termination point for broadband and integrates the routing gateway, set-top box, or home networking.

IPTV Client: The IPTV client is a functional unit in which the IPTV traffic ends. It performs functional processing. For example set top box.

Other IPTV Components

Video Head End

It contain number of components such as IP

IP gateway

It receives satellite, cable or other TV signals and broadcast these signals into IP network.

Middleware

It is centre to the IPTV system and attaches the Set top box present at the subscriber end to the Head end. It define user interface and fix the services.

Billing system

It manages the payment, traffic and financial information of the subscriber

VoD/nVoD server

Provide video on demand services. The device is a hardware storage device and contain multimedia library.

IP network

IP network has the multicast support for IPTV system. It directs the delivery of data to the multicast group.

Figure 3.2 Components of IPTV

Clients equipment’s

IPTV PC Client

It is a kind of software that enable users to access the IPTV services through PC.

Set-top boxes

Set-top boxes are used to access the IPTV services on TV monitor. They connect the middleware, content source and user or customer.

IPTV Protocols

IPTV basically of two types live TV and stored program such Video on Demand VOD. Playback feature of IPTV needs a personal computer or a set-top box which is connected to a TV

Protocols used in IPTV systems are-:

Live TV also called multicasting-: It uses IGMP version 2 or IGMP version 3 for IPv4

Video on Demand uses Real Time Streaming Protocol (RTSP).

Personal Video Recorder based up on Real Time Streaming Protocol.

Personal Video Recording is a customer service where real time broadcast TV is captured network server. It allows the user to view the pre-recorded programs on their schedule.

Subscribers can choose the programs which are available in the library (network based), whenever they want, not needing any device or remote control. But many people like to have their own PVR device because it allows them record whatever they want to record.

Summary

We discussed about implementation and Architecture of IPTV. There are various components such as content source, service node, Wide area distribution network and CPE which plays their specific role in the IPTV architecture. IPTV uses RTSP for video on demand and IGMP for live TV.

VIEWING IPTV AND QUALITY OF SERVICE

IPTV viewing devices allow the subscriber or customers to view and to use content from Internet TV system. The Internet TV viewing devices include standard televisions that use set top boxes, multimedia computers, multimedia mobile telephones, and web televisions etc. IPTV uses RTsP and

Viewing Devices

Multimedia Computer

A multimedia computer device is capable of processing multiple types of Medias. Computer normally has Internet connection and multimedia so it can be used to watch IP television by the help of media player. Media player finds the IP television media servers and get connected to them.

Analog Television Adapters (ATVA)

As the name indicates they convert digital broadband signal into the analog format for example PAL. We can use standard televisions for watching television channels that are sent on the data network such as the Internet by using analog television adapters. They are also called Set Top Box.

Figure 4.1 IPTV Viewing Devices

IP Television (IPTV)

These are the display devices which are made to receive and decode channels from the internet without needing ATVA. IP television consists of software which allows initializing and receiving Television through Internet using SIP.

Mobile-Telephone TV

Mobile telephone TV is capable of receiving and displaying digital information such as digital video and audio. They also have some embedded s/w which makes them ready to receive multimedia communication session. They may use compression algorithms because of limited bandwidth and higher cost

 .

IPTV Quality of services

In Internet Protocol Television systems, Quality-of- Service plays a critical role in the satisfaction of user or subscriber. There are certain factors which determine the Qos like Delay, jitter, bandwidth, noise etc.

Audio Quality

Audio Quality is the capability of the system to reproduce the important characteristic of the original audio signal. Quality of the audio can be affected by various such as the type of compression used how much Bandwidth available and which transmission mechanism to use. Normally more you compress sound lesser the sound quality.

A combination of good compression algorithm, higher bandwidth and good transmission medium provide the good audio quality. Some of the audio file formats are MP3, MP4, MIDI, MPEG, WAV etc.

Video Quality

Video quality plays very important role in IPTV systems. Video quality depends up on the ability of a system to recreate the key characteristic of the original video signals. Video quality is effected by the Video codec, transmission mechanism, and how much bandwidth available. There are high chances that there is some error pixel block or error in entire frame. To avoid these errors proper compression and transmission scheme should be used. Video normally follow MPEG standard for compression which is far better than most of compression schemes.

Summary

This chapter was about the various devises which are used for viewing the programs and provide the user different kind environment for viewing the video and other programs. Second part of this chapter discussed the quality of services for audio and video programs.

IPTV VS CONVENTIONAL TV TRANSMISSION TECHNIQUES

Satellite TV

In satellite TV also known as DTH signals are received using a dish antenna which is present at the subscriber site. Each dish antenna may have different specification according to broadcaster. Signals from the dish antenna received in encrypted form from the satellite and this antenna should be in direct alignment with the satellite location. An STB is placed at the customer side. The coaxial cable connects the STB to the antenna for signal reception. The STB works only after a certain amount of signal quality and strength has been acquired, which is fine-tuned by using the signal meter during installation of the dish antenna.

Digital Cable TV

Digital Cable TV or simply cable TV was one of the earliest systems to provide TV channels worldwide against the conventional terrestrial system. Previously it was started as analogue system but now a day it is all digitized with the help of set top box and it started with the analogue system. Signals from satellites were received at the multisystem operator end through multiple high-end dish antennae. These received signals were then multiplexed at the MSO end and finally transmitted to homes via coaxial cables.

IPTV VS DTH, Cable TV

IPTV is based on a two way protocol; it gives user greater interactivity with content and medium. By this provider can meet the wishes of subscribers. In current terrestrial broadcast system same content is broadcast to the all consumer’s homes, IPTV removes the fixed television schedule and provide consumers freedom of what to watch, when to watch and also give rewind, forward and pause features. In this way each house hold can create its custom content and viewing schedule

Figure below shows that opposed to traditional broadcast television where every home receives the same programming, IPTV allows each consumer to customize their viewing schedule.

Table 5.1 Operational and Performance comparison

IPTV in comparison to Internet TV and Internet Video

IPTV is the representation of a profile of a closed, proprietary TV system. This is somewhat similar to the present day cable service providers. But, unlike IPTV, it is delivered via IP-based secure channels. As a result, it sharply increases the control of content distribution. 

Internet Television is an open evolving framework where a huge number of small and medium-sized video producers contribute. Such a service provides highly innovative content, where the contributors are very much comfortable. This is due to the opening of different traditional channels which are either retail and for wide distribution.

Summary

This chapter discussed the conventional TV transmission systems such as DTH and Cable Television. They both were considered as good TV systems until IPTV came into play. Both of these are lack in providing the quality of service to the customer for example satellite television may be effected because of bad weather condition and in cable television quality degrade as the distance increase so IPTV came as a better option as compare to these two technologies.

Limitations

It is sensitive to packet loss or drop and some delay because for low bandwidth or slow connection.

Summary

There are enormous advantages that IPTV bring for subscriber, providers and other users. It offers fully digital content over secure network with quality of service feature. It also provide two way interactivity, control, selection and choices for user. There is some limitation too for this technology like packet loss but these can be overcome by increase in bandwidth.

IPTV- APPLICATIONS AND SERVICES

Applications and services

IPTV services are the providing of multimedia services (e.g. television) to customers by a common carrier, administration, or private operating agency using voice, data, and/or video technologies. There are numerous applications of IPTV which are described below.

Video on Demand (VoD)

The video-on-demand gives the freedom to each subscriber to view the video content according to their choice and requirement at the time they want. Video on demand provides the additional revenue generating services for example-::

• Movies on demand

• Stored programming content

Digital Broadcast TV

The advent of high speed DSL technologies such as GDSL, HDSL, VDSL and

VDSL2 gives the competitive alternate to IPTV. Currently IPTV offer only those channels that are currently viewed by customer but it has the capability to offer unlimited number of channels.

Enterprise (Company) Television

Enterprise programming is media that is created and managed for viewing by a company or for visitors it authorizes to view its programming content. Company television may be produced for the public and/or for internal communication purposes. Public company television channels may provide information about products, services or applications of the products or services that are of interest to the public. Internal ("in-house") company television programs may be used to provide employees with educational and company specific information (such as the location of a company meeting or party). Employees, vendors or others who are provided with access may distribute company television programs to monitors within company buildings or for distribution to multimedia computers that are only accessible by company employees.

Gaming

Gaming is an experience or actions of a person that are taken on a skill testing or entertainment application with the objective of winning or achieving a measurable level of success. Gaming services provided by IPTV systems may include game program distribution (downloading games), online gaming service, and multi-user network gaming or gambling.

Security Monitoring

Security systems are monitoring and alerting systems that are configured to provide surveillance and information recording for protection from burglary, fire, water hazard, and other types of losses. Video surveillance is the capturing of video for the observation of an area or location at another location. Traditional (legacy) security systems use proprietary sensing and transmission equipment, have limited control processing capabilities, and have interconnections that are limited to local geographic areas. The use of IPTV systems connected through standard data networks allows for the sending of media (such as digital video), powerful security system processing in a server, and wide area connectivity (such as through the Internet).

Figure 7.1 Security monitoring [HAR2006]

Advertising

Advertising is the communication of a message or media content to one or more potential customers. One of the most complicated areas for IPTV can be the management of advertising services. Advertising management is the process of creating, presenting, managing, purchasing and reporting of advertising programs. Because advertising services on IPTV systems can range from broadcast advertising to customized addressable advertising (custom ads for specific viewers), advertising management can be a complex but yet a very profitable process.

Figure 7.2 IPTV advertising messages [HAR2006]

Television Commerce (T-Commerce)

Television commerce (t-commerce) is a shopping medium that uses a television network to present products and process orders. The processes that used in t-commerce include advanced product offering catalogs (video catalogs), order processing, exchanging of order information between companies in near real-time and the ability to offer multiple forms of payments that may be collected by different companies. Key issues for IPTV t-commerce billing include transferring accounting records through multiple systems that transfer between multiple companies that allow for presentation, processing and payment of orders. Figure below shows how a television program can use mixed media to provide product offers to qualified consumers at specific times in a display location that is noticeable but not intrusive.

Figure7 .3 IPTV Television Commerce [HAR2006]

Anywhere Television Service

IPTV can also offer anywhere television to the subscriber. IP television subscriber needs to connected to data connection first time and send request for the temporary address from network. When connection is established it uses the internet address to get register with the Internet Television Service Provider. The ITVSP always know the current address of the IP television.

Summary

We discussed about applications op IPTV in this chapter. IPTV not only provide video services such as movies, serial, and songs but it also provides security, Message advertising and other commerce activity.

CONCLUSIONS AND RECOMMENDATIONS

Conclusions

IPTV is changing the way people receive and watch video programs and other multimedia contents. It also revolutionized the creation of content. Due to development in the broadband access and computing the industry IPTV is reaching its potential as a good programming platform that can give competition to satellite, cable and other TV mediums. Customers can greatly benefit from IPTV services by having greater flexibility in their video contents for example receiving video or audio of their choice. With the Video on demand the programs comes to the customer. Interactive applications provide the two ways interactivity by which user not only use IPTV as the entertainment option but can also use this as learning tool. IP video can also be used for society benefits such as screen installed in ambulances, police cars etc. It also allows doctors to send images across the world to discuss the data in real time through video.

IPTV is nowadays used as new content provider. IPTV is not only offering traditional programming but it is also used by anyone to produce television shows.

The video content is changing our web experience making it more robust for users, presenting data in more compelling formats that create interest in existing and new audience. Due to recent growth in the number of IPTV providers and users we can say that it’s an important technology in the TV Video market.

Recommendations

As we IPTV Offers lots of benefits to both customer and provider and other entities involved in this, but it’s still not gaining enough customers because of lack of knowledge in user community and people about the benefits and features of IPTV. It can grow at farther rate if people know about the benefits this technology brings.
