ABOUT TV ! Television (TV): specifies the medium of communication that operates through the transmission of information to the users as pictures and sounds for their interpretation & entertainment. MODES OF TV TRANSMISSION : 

ABOUT TV ! Television (TV): specifies the medium of communication that operates through the transmission of information to the users as pictures and sounds for their interpretation & entertainment. MODES OF TV TRANSMISSION Historic view-TV transmission from towers, distribution over a cable n/w or beamed directly from Satellite (VSAT). Modern view-TV, Telephone services & high speed internet access will be delivered over present broadband DSL Network on a single connection.

Types Of Transmission: 

Types Of Transmission MULTICASTING- A multicast stream is sent to a multicast group internet address. When a user selects a live channel, a request to join the group of viewers associated with the relevant multicast address is sent from the set top box to the equipment in the local telephone exchange. UNICASTING- A video-on-demand service is unique to each viewer & delivered as a unicast stream. It is sent to a single internet address in response to a request from the receiver.

Definition of IP-TV: 

Definition of IP-TV IPTV essentially has two components: Part 1: Internet Protocol (IP): specifies the format of packets and the addressing scheme. The protocol establishes a virtual connection between a destination and a source. IP allows you to address a package of information and drop it in the system, but there’s no direct link between you and the recipient. Part 2: Television (TV): specifies the medium of communication that operates through the transmission of pictures and sounds. We all know TV, but here we are referring to the services that are offered for the TV, like linear and on-demand programming.

Technologies involved in IP-TV :: 

1. Broadband – The key element As per TRAI: “An always-on data connection that is able to support interactive services, and has the capability of minimum download speed of 256 kbps ” Note : This definition for throughput may undergo up gradation in the future. Technologies involved in IP-TV :

2. xDSL: 

2. xDSL xDSL Family Tree Symmetric DSL Provide identical data rates upstream & downstream Asymmetric DSL Provide relatively lower rates upstream but higher rates downstream Four main variations of xDSL exist: ADSL - A symmetrical D igital S ub’s L ine HDSL - H igh bit/data rate D igital S ub’s L ine SDSL - - S ymmetric D igital S ub’s L ine VDSL - V ery-high-data-rate D igital S ub’s L ine

COMPRESSION TECHNOLOGY: 

COMPRESSION TECHNOLOGY H.264 is mainly used It has 50% more compression efficiency as compared to MPEG-2 Picture quality is retained at low bit rates It enables the broadcast of HD over IPTV

Comparison between H.264 & MPEG2: 

Comparison between H.264 & MPEG2 H.264 MPEG2 Variety of entropy schemes used Fixed entropy technique used Smaller block size varies (4*4,16*16) Fixed block size (16*16) Have in-block deblocking No such feature Computationally demanding Computationally less demanding Supports HDTV Transmission Supports SDTV Transmission Resolution of 2000,000 pixels Resolution of 210,000 pixels Broadcast in 16:9 format Broadcast in 14:3 format

Advantages of IPTV: 

Advantages of IPTV Traditional TV Distribution IPTV Proprietary STB lease Proprietary systems Tied to single STB vendor technology roadmap Cheaper STB Scale efficiencies and merchant components will ensure cheaper devices and better availability Thin client will be embedded in various devices (such as XBox) Broadcast architecture No 1:1 potential without monumental upgrade cost Video delivery separate from data Difficult to integrate with Web/PC content and services Would need to shift analog subs to digital to free up bandwidth for IP video (hence free digital STBs offers to move subs off of analog spectrum) Shifting to IP Video requires new IP-STB 1:1 communication will enable Targeted custom TV services and commerce Collection of usage data Simplified integration of IP content and services (ITV - weather, games, photos, music etc. on TV) Little or no interoperability TV integrated with broadband home devices The IP STB is the TV’s gateway to digital music, home videos and photos IPTV Reinvents Entertainment in the Home
