How to Connect SDI/HDMI Signal to Computer for Live Streaming?

The NDI transmission scheme is a more efficient IP-based transmission scheme. Install the NDI discovery software on the computer and connect the small-sized NDI encoder to the signal source and the on-site IP network，the multi-channel transmission of any SDI/HDMI signal can be achieved then.

When you need to collect SDI/HDMI video sources such as cameras, drones, game consoles, etc. into your computer for video conferencing, or live webcasts, there are capture card connection solutions on the market for one and NDI network connection schemefor another. As of capture card solution it needs to install a capture card (or connect a capture box) to the computer, connect via the SDI/HDMI physical signal line, and transmit signals one-by-one.

The NDI transmission scheme is a more efficient IP-based transmission scheme. Install the NDI discovery software on the computer and connect the small-sized NDI encoder to the signal source and the on-site IP network to achieve multi-channel transmission of any SDI/HDMI signal. The project has the following advantages:

1) No cables on site: It only needs to install the NDI encoder on the camera to connect the signal source and the network cable, and the back-end computer can be connected to the network to complete the deployment easily, eliminating the need for complicated SDI/HDMI connections and computer hardware installation. The transmission distance is not limited (transmission within the same LAN is sufficient).

2) Multi-channel transmission: the back-end computer can receive any front-end video source, or any front-end video source can be received by multiple back-end computers at the same time (the number of channels is related to the on-site network bandwidth).

3) Low latency and high synchronization: The end-to-end latency of NDI transmission is as low as less than 100ms, and precise frame synchronization has been achieved.
