Reflections on Chapter 7

Streaming is a method of delivering an audio and video signal to your computer over the Internet, and differs from the normal method of receiving Internet audio and video in one important way instead of having to download a wav, au or other type of file completely before being able to listen to it and see, you hear the sound and see the video as it arrives at your computer, and therefore do not have to wait for a complete download which would be difficult with a live broadcast anyway!As the data arrives it is buffered for a few seconds and then playback begins. As the audio is playing, more data is constantly arriving or streaming, and as long as you are receiving a constant stream of data, you should hear constant audio. Obviously you'll need a soundcard, speakers or headphones and the appropriate software for this all to work. Think of a bucket the buffer with a hole in the bottom, being topped up with water the data. As long as there is water in the bucket, it will continue to pour out of the hole, and will do this as long as there is water in the bucket. Similarly, as long as there is data in the buffer, you will continue to hear sound. Unfortunately the buffer can empty due to congestion on the Internet which may stop you from receiving data this explains the net congestion buffers the message so you may see from time to time with the RealAudio software. Media has been altered by web-casting. Web-casting is used for live events where there can be potentially many viewers. Web-casting delivers one stream to many students simultaneously. It is essential to note that streaming serves require the appropriate hardware, network connections, and basic usage knowledge. The advantages can be seen through the creativity in the classroom, by students being able to visualize or receive auditory instructions. This type of media will help the classroom environment through communication and complex streaming.
