D300 Plus/ Pro media gateway is a high-performance embedded multi-functional device, which integrates functions such as stream media protocol conversion, stream media distribution service, multi-channels video decoding and video image segmentation. It can be applied to video format conversion, protocol intercommunication, decoding and splitting display from different systems, different manufacturers, different types and different encoding ways. It also works as the stream media server with the capability for 100 concurrent access.
D300 Plus/ Pro Media Gateway
● It supports the most comprehensive protocol conversion and the widest application, which covered various stream media protocols in the market including professional protocols such as SIP and GB/ T28181.
● Support stream media protocol conversion, stream media distribution, live streaming, video split display, audio digital remix, video decoding to the display wall, etc.
● Portable design, low power consumption (<6w), stable and reliable working mode makes 7×24 hours working available.
It can be widely applied to RTSP/Onvif LAN monitoring or other IP-Camera video live broadcast over public network, such as scenic spot, store monitoring, campus monitoring, farm monitoring, etc., it can realize the functions of multi-camera, multi-angle switching.
All kinds of non-unified video can be converted to video that can meet the national GB/T28181 standard and international SIP standard, which can connect the traditional communities, parks, enterprises and institutions monitoring to relevant government platforms.
Multi-parties video collaboration; SIP video conference to live webcast; IP stream distribution (forwarding) / switching / live broadcasting; stream media decoding to the display wall (RTMP / RTSP / TS-UDP and other stream media to SDI or HDMI); multi-channels split screen display, etc.
Scenic spot monitoring live broadcast Gourmet store monitoring live broadcast
Campus monitoring to public security network Push the video after split
Support 4 channels (D300 Plus) or 9 channels (D300 Pro) stream media protocol conversion
● It supports the conversion of RTP/RTSP/SRT, TS over UDP, RTMP (service and push), HLS (m3u8), SIP (multi-parties conference mode), GB/T28181, Onvif and other media protocols that are software extendable, makes various input protocol streams can be converted to other target protocol.
● The transmission/ reception of NDI-HX protocol can also be supported with additional application authorization.
● Compatible with various IP cameras, IP encoders, NVRs, video conference systems input.
● Supports up to 4 channels (D300 Plus) or 9 channels (D300 Pro) input video streams’ protocol conversion (Media source number is unlimited and can be dynamically switched), and each input stream can be converted into 4 different target protocol stream outputs, or 4 identical protocols stream output;
● Expandable SATA and NAS video record and storage capability.
Stream service function for up to 100 concurrent access capability (streaming distribution/ live broadcasting)
● It has 4 channels (D300 Plus) or 9 channels (D300 Pro) of network streaming distribution/ live broadcasting function (each stream can be pushed to up to 4 different live broadcast targets simultaneously), and support various live broadcast protocols such as RTMP;
● Unicast mode can meet up to 100 concurrent user viewing, it can be used directly as a distributed live broadcast server for live events such as education/ conference/ broadcast program/ digital signage etc..
(Note: The actual of concurrent access capability depends on the specific network bandwidth, video format and other factors. Device transmission limit is 600Mbps.)
