A more affordable selection is to combine off-the-shelf video products.

Every video feed takes "A" number of bandwidth, so the whole bandwidth required is the number of streams multiplied by A.
Though video might be only one compact chunk of targeted traffic traversing your network, its influence cannot be dismissed.

Considering that even well-engineered IP networks have a tendency to possess a little residual packet decline rate due to low-likelihood statistical congestion situations and amplification of bit glitches in the underlying components, most Specialist solutions use some sort of ahead error correction to make certain the encoded video stream can be reconstructed even though some packets are misplaced.
IP multicasting will allow the distribution of video and audio to 小蓝视频网 any supported quantity of shows with a network.
