PRESENTATION ON IPTV

WHAT IS IPTV It is a technology that delivers video or TV broadcasts over the Internet. Internet TV, in simple terms, is video and audio delivered over an Internet connection. It's also known as Internet protocol television, or IPTV. You can watch Internet TV on a computer screen, a television screen (through a set-top box) or a mobile device like a cell phone.

HISTORY OF IPTV In year 1994, ABC's World News was the first television show to be broadcasted over the Internet. Term IPTV first appeared in 1995 with the founding of Precept Software by Judith Estrin and Bill Carrico . Software was written primarily by Steve Casner, Karl Auerbach, and Cha Chee Kuan.

WHY IS IT REVOLUTIONARY? True interactive television. See anything you want to see, any time, any where, on any device . Reduced infrastructure costs. IPTV works on your existing internet connection . Infinite number of channels .

EARLIER….. the only ways to watch television were through over-the-air broadcasts and cable signals. With broadcast TV, an antenna picks up radio waves to transmit pictures and sound to your television set. With cable TV, wires connect to your TV itself & these wires run from your house to the nearest cable TV station, which acts as one big antenna.

IPTV TYPES Live broadcasts - it's like watching live TV on your computer screen. You can't pause, back up or skip through parts of the broadcast that don't interest you. On-demand videos- arranged like a playlist. Episodes or clips are arranged by title or channel or in categories like news, sports or music videos. You choose exactly what you want to watch, when you want to watch it.

How can IPTV compete with existing TV services? Price: Get your telephone, data and video (called a “Triple Play”) for a monthly cost. Return path: watching TV on an IP connected service allows delivery of a wide range of extra services from ads to interactive options. An IPTV supplier can push out multiple new channels across their existing bandwidth relatively easily.

Why is IPTV happening now? Bandwidth is important for Internet TV, because sending large amounts of video and audio data over the Internet requires large bandwidths.

STREAMING AUDIO AND VIDEO Basic steps to watching streaming audio and video : A server holds video data. When you want to watch a video, you click the right command, like "Play" or "Watch." This sends a message to the server, telling it that you want to watch a certain video. The server responds by sending you the necessary data. It uses streaming media protocols to make sure the data arrives in good condition and with all the pieces in the right order.
