Bit Streaming<\/h2>\n

What is a bit stream?<\/h3>\n

A bit stream is a continuous flow of bits over a communication path. This path can be within the computer itself, across computer networks from a source computer (usually some sort of server) to a destination computer. We will be focusing on network bit streams and two ways in which they can be handled.<\/p>\n

Sports fixtures often use real time video streaming<\/p><\/div>\n

Real time bit streaming is where is data is retrieved live from the source as it is being created. Real time streaming cannot be paused or re-winded, as any data that is not immediately used (e.g. video data outputted to the screen) is discarded.<\/p>\n

Features:<\/strong><\/p>\n

Low latency(delay) is prioritised over quality – packets that don’t arrive in time are discarded.
\nIf the data cannot be reliably streamed at the current bit-rate(quality) then a lower bit-rate and quality will be used.<\/p>\n
