Multistreaming for Remote User Access
Multistreaming can also be used to setup a lower quality stream for remote users and still keep a high-resolution stream for local viewing and recording. This is often necessary when the administrator of the video management system does not have the control over the capacity of the external network. Therefore, utilizing a stream that requires low bandwidth can ensure that remote users always have access to the video, wherever they are.
Multistreaming for Maximized Tile Viewing
Another useful application for multistreaming is the ability to access the different streams directly from the operator screen. For example, sometimes operators like to view up to 16 cameras on the same monitor. If the streams are configured at 4CIF 30fps at around 4 Mbps, it will consume 64 Mbps of bandwidth as the data transmits to the client station. The size of the viewing tiles in a 16-camera layout on a 20’’ monitor might not required a 4CIF resolution quality, and therefore having the ability to switch to a lower resolution stream, CIF for example, will have a direct impact on the required bandwidth, without affecting the viewing quality. See figure 7 below.
