Streaming methods allow for the transmission of data via the network, where the transmission quality of live and recorded images is equal to the recording quality at the recorder. The disadvantage is that the transmission of the usually large fi les requires a high bandwidth.
Dual Stream resolves this problem by choosing a different quality for the transmission of live pictures than is chosen for recording them. This means that recording is done in high quality, whereas a lower quality is chosen for the transmission, hence leading to a
lower network load.
Like Dual Stream, PRemote enables the transmission of pictures using lower bit rates. It does offer some further advantages though. While with Dual Stream it is only possible to change the transmission quality of live pictures, PRemote also allows for the transmission of recorded images at lower bandwidths.
With Dual Stream an active connection with a camera can be set up, consequently leading to only one split. PRemote, however, enables a 16 time multi-split.
PRemote generally requires less bandwidth than Dual Stream, therefore only PRemote is suitable for use of ISDN.
