What is streaming video

Streaming video is the process of converting digital video and audio in a compressed format, and distribution of data over computer networks. These compressed data can be easily achieved with computer networks to their smaller size. The video and audio content can be live or recorded, and can be streamed or delivered, as the application is running.

streaming video over the Internet is similar to standard television.The software is used in network video and audio format to a computer that is suitable for delivery to a. TV channel specialized hardware to convert audio and video data in a format suitable. Special computer network transport protocols enable the delivery of multimedia content for the (viewer) than using radio transmitters to send consumers the content is video and audio to individual television.

The first step in theVideo streaming is the process of compressed digital video and audio content. This is necessary for the bandwidth that is used to preserve the delivery of content. Specially developed software, called codecs, are used to compress the video and audio. The codec to use mathematical algorithms to compress data. Most codecs use a method known as data compression, lossy compression. This method allows you to lose the content compressionthe quality of the original video and audio content. advanced codecs require large amounts of computer resources for high-definition video and audio data compression. There must be a balance between the quality of compression, bandwidth consumed and the resources of the computer set up. This balance ensures a quality viewing and listening experience for everyone.

The next step is to publish content to the encoded video and audio. special server software is needed tothe continuous distribution of multimedia content. This special software be installed and run on multiple operating systems including Windows, Linux and Macintosh, along with many other operating systems. The individual files on your needs, to deliver content without the need for special server software. can be hosted on a request to change your content using a standard Web site.

The last step is the compressed content to prepare for deployment.the audio and video to computer network architecture used for distributing content and requirements of end users of the procedure for submitting data for the transport of content on computer networks compression is determined by several factors including: the use of software. Delivery of data over computer networks using special software or hardware instructions to route video and audio content to the consumer. Each network protocol to transport the computer has its ownunique properties that make it applicable in certain situations. methods of transportation of multimedia data are: HTTP, RTSP, IP Multicast and P2P.

No license to transmit or technical certification is required for streaming on the Internet, unlike a standard TV. Standard TV stations are required to have a certified transmission and broadcast engineers. The only requirements for video streaming on the Internet are: the transmission of specialized dataServer software, special audio and video encoding software and large amounts of bandwidth. The bandwidth required for users with the provision of video and audio content at the end. The formula for determining the amount of bandwidth for streaming video and 'request: bytes = required data encryption speed x number of users required a row.

All multimedia content is subject to intellectual property laws. These requirements differ from countryin the country, but the general rule for audio and video content, the source station the web or stream must have a license to distribute itself is copyrighted material hereto. The content that is published under a Creative Commons Public Domain, or fell out of copyright protection is not the subject of intellectual property rights and rules may be transferred without the demand for content license.
