1. What is the video gateway? The video gateway is a protocol converter, also known as a network connector, and the video gateway is the network interconnection between the network layer, that is, network interconnect. It is the most complex network interconnect device for different network interconnections than two high-level protocols. The video gateway can be used for both wide area network interconnects or for local area network interconnects. The gateway is a computer system or device that acts as a transformation. Use between different communication protocols, data formats, or languages, and even the architecture is completely different. 2. Video Gateway Features Video Gateway is a node that connects two or more management's different network / subnets, is a storage forwarding device, video gateway is a high-performance embedded multi-function media gateway device , Centralized media protocol conversion, streaming media distribution service, multi-channel video decoding, video screen segmentation and other core functions. 3, Basic Terms 1, the transfer gateway is used to establish a transmission connection between 2 networks. Using the transport gateway, the host between the hosts on different networks can establish, cascaded, point-to-point transmission connection. 2. The application gateway performs protocol conversion on the application layer. For example, a host is executing the ISO email standard, and the other host is executing the Internet email standard. If the two hosts need to exchange emails, then the email gateway must be converted, this email gateway is a Application gateway. 4. Setting the gateway Auto setting is to use the DHCP server to move to the computer in the network to assign an IP address, subnet mask, and default gateway. The advantage of this is that once the default gateway of the network changes, as long as the settings of the default gateway in the DHCP server are changed, all the computers in the network have got the IP address of the new default gateway. This approach is applicable to a network whose network is large, and the TCP / IP parameters may change. 5, video gateway application scenarios can be applied to format video conversions of different systems, different manufacturers, different types, and different coding, protocol interoperability, decoding output, and split display, and implement 100 stream media accessible within 100 concurrency Server features. Can be used to monitor the live broadcast, monitor the GB28181, RTSP to RTMP, UDP to RTMP, monitor access public security network, etc .; 6, video access gateway technology is wider: monitoring vision is unlimited, covering large quantities of Tianwang monitoring blind spoles Time: Save a large number of manpower required for video copies, more time saving: Take advantage of existing networks and equipment, a large number of reduced access costs is safer: multi-layer isolation is highly stable, does not affect the original system running D300PLUS / Pro video gateway at the same time 4 Road or 9 streaming media protocol conversion, supports transitions including RTP / RTSP, TS Over UDP, RTMP (Service, and Push), HLS (M3U8), GB / T28181, ONVIF, and other software scalable media protocols. Support 16 channels of video decoding and custom split display, and support multi-channel video dynamics support UHD (4K) / HD H.264 / H.265 video decoding, the device comes with the HDMI and SDI output interface. Support HDMI (3840x2160 @ 60Hz) and SDI (1920x1080 @ 60Hz) on the same screen or discrete output; support HDMI / SDI embedded audio output and analog audio output, the audio channel can be switched, support high quality digital mixing and conference mode mix 4 channels 4K 30Hz H.264 / H.265 video; or 8-way 1080p 50Hz / 60Hz H.264 / H.265 video; or 16-way 1080p 30Hz or 1080i 50/60Hz or 720P and below H.264 /H.265 video; support 16 channels of video custom 1/2/4/6/8/9/16 Split display, as well as dynamic switching output; also supports the network live after re-encoding the restructuring of the restructuring / Transmission, the image maximum support 1080p60 H.264 encoding.
