Hdot 01 is video server for the coding of analog video signals with PAL/NTSC standard, for the transmission over LAN with IP protocols and for the decoding of streamed video to analog video.

Design and manufactured by Sinartis, Hdot 01 is a video codec (encoder/decoder) using H.264, MPEG4 and H.263 compression standards and in addition, it is able to transmit JPEG still images at a pre-set rate.

The compressions standards, frame resolutions and bit rates (VBR or CBR) with flux from 32 Kb/s to 5 Mb/s are very easy selectable by a web page interface.

The video resolutions are ranging from Full D1 (720x576 pixels) to QCIF (176x144pixels) up to the maximum frame rate (25 fr/sec PAL or 30fr/sec per NTSC). 

The LAN protocoIs are both RTSP and RTP  (Elementary Stream) both unicast and multicast.  

The video/audio streams can be decode over the LAN by PC servers using programs like   VLC media player, QuickTime player, Mplayer.

Hdot 01 has aslo, as an the option,  a USB interface connector for the connection of external functionality  (for example a recording Hard Disk or a Wireless connection) and in addition the capability to record  video streams and JPEG still images over a built in Memory Card socket.

The analog audio input and analog audio decoded output are both stereo. 

When working as a video decoder Hdot 01 has in addition to the standard composite video BNC connector, a S-Video output connector for a best quality analog signal output.

Hdot 01 was design using low consumption electronic components.
