IPTV System

This figure shows a sample IPTV system. This

diagram shows the IPTV system gathers contentfrom a variety of sources including network

feeds, stored media, communication links and

live studio sources. The headend converts the

media sources into a form that can be managed

and distributed. The asset management system

stores, moves and sends out (playout) the mediaat scheduled times. The distribution system

simultaneously transfers multiple channels to

users who are connected to the IPTV system.

Users view IPTV programming on analog

televisions that converted by adapter box (IP set

top box), on multimedia computers or on IPtelevisions (data only televisions).

IP STB

This figure shows a functional block diagram of

an IP STB. This diagram shows that an IP STB

typically receives IP packets that areencapsulated in Ethernet packets. The IP STB

extracts the IP packets to obtain the transport

stream (TS). The channel decoder detects and

corrects errors and provides the transport stream

to the descrambler assembly. The descrambler

assembly receives key information from either a

smart card or from an external conditional

access system (e.g. via a return channel). Using

the key(s), the STB can decode the transport

stream and the program selector can extract the

specific program stream that the user has

selected. The IP STB then demultiplexes the

transport stream to obtain the programinformation. The program table allows the IP

STB to know which streams are for video, audio

and other media for that program. The program

stream is then divided into its elementary

streams (voice, audio and control) which is

supplied to a compositor that create the videosignal that the television can display.

IP Video System

This figure shows how video can be sent via an

IP transmission system. This diagram shows thatan IP video system digitizes and reformats the

original video, codes and/or compresses the

data, adds IP address information to each packet,

transfers the packets through a packet data

network, recombines the packets and extracts the

digitized video, decodes the data and convertsthe digital video back into its original video

form.
