With the birth of the World Wide Web, a number of other technologies were born as well. For instance, internet television was made possible. Internet TV or internet protocol television (IPTV) refers to video and audio that’s delivered over an internet connection. As this technology is slowly gaining popularity, it also gradually replaces conventional TV. But how do you watch streaming TV online?
You have to know that there are two things that make internet TV work. Number one is bandwidth, which is a bit rate measure of available or consumed data communication resources that is expressed in bits per second, or multiples of it. Bandwidth is important mainly because large bandwidths are required in order to send large amounts of video and audio data over the Internet.
Number two is streaming audio and video. When we say streaming, we are referring to the normal flow of data as it travels from a server to someone’s desktop computer through a network connection. Streaming is important because this technology is what makes it possible for us to watch either live or on-demand video without us having to download a copy directly to a computer.
While there are indeed a wide variety of sites that offer live streaming, different options also exist for moving video across a home network. The use of digital media receivers (DMRs), for instance, integrates a software program into the free Windows Media Player 11. This method works with the Windows Media Connect file-sharing protocol as it streams the video or the DRM move without licenses ever being violated. The problem with these systems, however, is that they work best over an Ethernet connection or a Wireless G or N connection with a speed of at least 54 megabits per second.
Streaming video works by using either Real Time Stream Protocol (RTSP) or Hypertext Transfer Protocol (HTTP). This method works by moving all data to a user’s machine over a network connection and streaming it at a speed that depends on the network connection. However, video has to undergo a process known as encoding first before it can be transmitted across the internet for streaming. In the encoding process, the video file is simply converted into a format that is suitable for digital transfer. Special software applications are used to convert the video into a digital file that can easily be broken down into data packets and sent across an internet connection.
