Mobile IPTV is a technology that enables users to transmit and receive multimedia traffic including television signal, video, audio, text and graphic services through IP-based the wired and wirelessnetworks with support for QoS/QoS, security, mobility, and interactive functions. Through Mobile IPTV, users can enjoy IPTV services anywhere and even while on the move.
A key first step in providing Internet Protocol Television service is converting the analog audio voice signals into a digital form (digitization) and then compressing the digitized information into a more efficient form.Digitization is the conversion of analog signals (continually varying signals) into digital form (signals that have only two levels). To convert analog signals to digital form, the analog signal is sampled and digitized by using an analog-to-digital (pronounced A to D) co the A/D converter periodically senses (samples) the level of the analog signal and creates a binary number or series of digital pulses that represent the level of the signal.
In fact, IPTV is composed of Internet Protocol (IP) and TV. In other words,it implies a traditionalTV services are being migrated and converged Into Internet space. As long as we use Internet, IP is avital component and all of advantages of IP can be used for IPTV services. Everyone agrees that IP hasplayed and will play a major role in the evolution of networks and services. IP allows you to make use ofall IP based services including IPTV services anywhere on earth through Internet. The major goal of this paper is to raise theinterests and concerns of Mobile IPTV including thestatus of standard activities when deploying IPTVservices over wireless and mobile networks, and expand the value of IPTV in the structure ofeveryday life
HOW MOBILE IPTV WORKS
Before we get into the internal details of the way the IPTV network is configured to provide transmission of television signals, we see what are the various steps followed to convert the audio and video feed signals into a suitable form to be transmitted in the form of IP (Internet Protocol) packets, which forms the basis of the whole concept of IPTV and how they are received on the other side as television signals.
