A less expensive possibility is to combine off-the-shelf video products and solutions. Outside of the hardware, the particular distribution technique is crucial: For one particular-to-one distribution, you require a lot of bandwidth and horsepower to support the utmost quantity of envisioned streams. Each video feed normally takes "A" level of bandwidth, so the overall bandwidth needed is the amount of streams multiplied by A.
Network hold off variation can be retained to some minimum amount through the use of a large-speed network spine, and guaranteeing that video site visitors would not face excessive queue delays.
