PRemote-HD: Turbo transmission of HDTV streams at low bandwidths

© Dallmeier electronic
With PRemote-HD Dallmeier has developed a special method that enables the transmission of HDTV streams even at low bandwidths.

PRemote-HD is a method developed by Dallmeier that uses transcoding to enable the transmission of HD and megapixel streams even at low bandwidths. PRemote-HD is particularly useful for locations where images need to be recorded at highest quality but have only a low-bandwidth network available, for example DSL networks with a 128 kbit upload.

As opposed to standard transmission methods such as Dual Streaming that allow users to only change quality settings for the transmission of live images, PRemote-HD also offers a bandwidth-saving transmission of recorded images. Therefore, it is not only possible to view live images, but also to evaluate recordings over great distances in highest resolution.

PRemote-HD furthermore enables so-called split streaming for SD cameras, i.e. a multi-split (up to 16x split) is transmitted in just one image. Consequently only one stream is necessary. It is possible to quickly and conveniently switch from split to single image with a mouse click.

Good to know: PRemote-HD not only supports Dallmeier cameras but also third-party IP cameras that are recorded via RTSP method in MJPEG or H.264 format.

SmartZoom functionality
SmartZoom is a very special kind of zoom functionality. With SmartZoom the relevant image area that is zoomed in (picture of interest) is cut out from total image (cropping). Only that image section is transmitted. Thereby the size of the image is reduced without changing its resolution. In other words, it is possible to achieve a higher resolution and thus higher richness of detail while the bit rate remains the same.

Later upgrades possible
PRemote-HD is available for Dallmeier DMS and DLS recorders as well as the VideoNetBox and Smatrix. It is possible to subsequently activate PRemote-HD on already purchased systems once they have been updated to the appropriate software version.
