Video encoding/Software video compression is a digital video processing technique aimed at reducing the bit rate of streamed video and bandwidth consumption. Video is compressed procedure of software processing of a digitized video stream in order to reduce its volume. Compression is performed according to a specific software algorithm − codec.

To compress video signals from IP - devices, standard codecs such as algorithms (for example, MPEG-4 or vendor's proprietary codecs ) or algorithms developed by the manufacturers of these devices are used.

Before displaying the To display a compressed video signal on the screen, it the video signal is automatically decompressed beforehand. 

If the video resolution of a viewing tile is lower than that of compressed video, only part of the video stream is decoded. This reduces CPU load on Axxon One Сlients. Partial decoding does not affect bandwidth requirements. Partial decoding works the remote devices on the layout is less than the compressed video resolution, Axxon One performs partial decompression of the video signal, which reduces the load on the processor of the computer that performs decompression. The network load isn't reduced. Partial decompression is possible with MPEG-2, MJPEG and MxPEG codecs.
