It includes broadband,ADSL,Wi-Fi,cable and satellite. ARCHITECTURE OF IPTV CONTD’ IMS architecture for IPTV ‘ There is a growing standardization effort on the use of the 3GPP IP Multimedia Subsystem(IMS) as an architecture for supporting the IPTV services in carrier networks. Both the ITU-T and ETSI works on the ‘IMS-based IPTV’ standards. WORKING PROCEDURE The TV signal is converted into small packets of computer data like any other form of online traffic such as the email or a web page. Then the channels are encoded in IP format and delivered to the TV through the set top box. The IPTV services also include video on demand(VOD),which is similar to watching video CDs/DVDs using a VCD/DVD player.

LIMITATIONS As the IPTV is based on the Internet Protocol ,it is sensitive to packet loss and delays. If the IPTV connection is not fast enough the picture might break-up or loss may occur. The Satellite Internet Access is not ideal for IPTV due to its high latency. The video data is compressed a lot, so the picture quality is poor compared to other DTH & Digital quality. HURDLES TO CROSS The backbone of IPTV is broadband. And India has only 12.01 million broadband connections till date. The availability of the last mile is a factor that is most instrumental in determining what the future of broadband in India is going to be. IPTV suffers from jitters. IPTV requires 33% more bandwidth than radio frequency for the same result with the same codes. IPTV Requirements ”Bandwidth for access links 4 Mbps per channel for SDTV HDTV:20 Mbps per channel Vod ”Quality of experience(QOE) ‘ Step beyond QoS IPTV SOFTWARE VENDORS ‘ALCATEL ‘MICROSOFT ‘ORCA INTERACTIVE ‘SIEMENS ‘VIDEO FURNACE ‘MOTOROLA ‘THOMSON IPTV Innovation 0228598 CONCLUSION IPTV involves low cost tv services for both customer and provider.
