Since the advent of the internet, doing many interactive things including video streaming has become possible. The power of dynamic internet allows a person to transmit both audio as well as video at very high speeds; so that things like video streaming and teleconferencing become possible. In essence, video streaming is nothing more than taking a video and audio signal at the source and transmitting across the internet. This allows you to send any interactive video stream to any website that can receive dynamic data. The website that is displaying the video stream must have a special script that can show your video and audio stream. Genetec Video Wall
You can easily create video streaming with nothing more than a simple microphone and a webcam or you can use more advanced equipment to generate the required signal. In addition, you will need some sort of an encoder software that will help you to transform the signal into a continuous stream. In order to achieve this, the streaming data have to be broken into packets and each packet needs to be checked at the moment of streaming in order to make sure that the data integrity is maintained. If there is an encoding problem, this can cause the loss of the coherence of the visual data, which can cause problems at the reception end as well. Otherwise visual frames as well as audio packets will be dropped during transmission and this can make the broadcast lose its overall coherency. Usually, the signal integrity can depend on your internet connection speed, as well as the quality of the line itself. Your internet connection should be good enough so that the data packets are also being forwarded to your ISP with minimal loss. In addition, your connection should have an overall stability for extended periods of time since internet broadcasting o streaming will usually take place for some time. An unstable connection can cause lot of dropped frames in your video stream.
The most popular type of encoding in video streaming is flash streaming. The greatest advantage of flash streaming is that it can be played back in any kind of a browser. You can easily use Internet Explorer, Firefox Mozilla, Google Chrome or even Opera to play back any flash streaming regardless of the computer or the operating system that is being used. Hence, whether the user is using an Apple computer or a classic PC won’t matter and even using Windows or Linux will not make a difference in playing back the stream. However, the main problem with flash streaming is the fact that it will use a larger amount of bandwidth and this can make it an issue in terms of bandwidth availability.
The second type of encoding mechanism that you can use is Shoutcast streaming. In fact, shoutcast streaming is a very popular streaming method that has been in use for over a decade. It is especially used for audio streaming and for internet radio stations, since it is an inexpensive and easy way of streaming. The shoutcast streaming encoder actually uses a sort of MP3 encoder that is Winamp compatible, so that it can be played back in variety of different platforms including Winamp player as well as VLC player. Especially, many online radio stations have popped up after the usage of Shoutcast streaming. However, the main disadvantage of Shoutcast streaming is the fact that especially video signals can be hard to playback in different type of browsers. Thus, you may end up using different scripts for different browsers and this may not be necessarily sensible for a website that displays video streaming. However, for audio streaming Shoutcast still remains the best option.
