IPTV is short for Internet Protocol Television. Through the years, people from all over the world have discovered and loved the benefits of IPTV technology. You should remember that this kind of TV is only able to be accessed by individuals who have access to rapid and stable Online connections iptv. Consumers might also want to be aware that IP television varies from Internet Television. With Internet TV, users have to have a Personal Computer to look at programmes, however with Internet Protocol TV, consumers need an IPTV facilitated TV set as well as the necessary hardware.
Using this type of technological innovation, consumers can view Live TV via the Internet. For instance, consumers can watch news and their preferred TV shows live, just like in cable and satellite Television. The only difference is that this technology delivers high resolution pictures with much better picture and sound quality.
Viewers also get access to VOD or video on demand. This particular service allows them to view prior episodes of their favorite shows or any other video that is available on the net. As an illustration, the elderly can watch classic films and TV shows they used to watch throughout their prime years. The VOD service is really popular and is amongst the instrumental aspects to the rise in popularity of Internet protocol TV.
Internet protocol TV enables users to rewind a TV show, so that they can start off watching it from the beginning. Time-shifted Television allows consumers to watch shows that had been shown several hours or days ago. With this type of TV, gone are the days when you simply had to modify your schedule to hurry home to watch your favourite show.
Unlike satellite television, Internet Protocol television cannot be plagued by lousy weather conditions. Most Satellite Television consumers often whine about very poor signal or interruption of transmission because of poor weather. With Internet Protocol TV, you will not have to worry about such complications. Users also don’t have to buy big satellite dishes so that they can receive a signal.
The sheer numbers of IPTV end users is predicted to increase drastically over the next few years as more and more folks come to enjoy what it really has to offer. While searching for service providers, be certain they feature free installation simply because setting up the equipment could be tricky at times. You may also choose to compare prices before you decide to subscribe to any service. Different providers have different rates, so you can save lots of money by just doing your research to compare prices.
Mobile TV can be watched on a smart or 3G mobile phone, such as the LG Vu or Samsung SCH u620 smart phone. Both AT&T Wireless and Verizon Wireless offer mobile TV services. For Verizon, it is VCAST TV and for AT&T, it is AT&T Mobile TV. Both AT&T and Verizon Mobile TV use MediaFLO technologies from Qualcomm to broadcast the VHF (719 MHz Center frequency) digital TV signals to the mobile phones. Mobile TV service from different carrier bundle different set of TV channels in its broadcast (in the range of 10 to 12 TV channels in a basic package).
Mobile TV service does not use the mobile phone network to transmit the TV signals. Instead, it uses a separate network to distribute, transmit and broadcast the TV signals to the mobile phones. It only uses the mobile phone network to provide interactivity and user authorization with the TV service provider. Since the 3G mobile phone network from AT&T and Verizon are both capable to carry IP traffic, it seems to be obvious that the simplest implementation for mobile TV is using IPTV. A good example is AT&T already using IPTV in its U-verse service (internet, phone and TV).
To understand why mobile TV does not use IPTV, the unicast nature of the mobile phone network needs to be explained. The current 3G (UMTS, EVDO) mobile phone network are designed to carry unicast traffic only, i.e. point to point connection needs to be establish between the user and the Media server in order for the network to deliver the TV traffic to the mobile phone. Since TV is a broadcast service, i.e. a point to multipoint connection is required for mobile TV service. To implement point to multipoint connection, the mobile phone network needs to set up an IP connection between the Media server and each mobile user receiving the broadcast simultaneously. These many connections will easily overrun the capacity of the mobile phone network and blocks other voice and data traffic that needs to use the network.
For mobile TV to use IPTV, the IP multicast feature needs to be implemented on the mobile phone network. Multicasting is the technique of transmitting a single video signal simultaneously to multiple end users. All viewers receive the same signal at the same time but there are no separate streams (connections) for each recipient. IP multicast is widely used in the delivery of broadcast TV services over IP networks. It significantly reduces the amount of bandwidth required to transmit high quality IPTV content across a network. This is because only a single copy of every video stream needs to be sent to a router, which in turn makes a copy of that stream for the requesting devices. Not only does multicast reduce the bandwidth requirements of the network but the processing power of the Media server can also be kept relatively low because it only transmits one copy of an IPTV stream at a time.
