NewTek NDI 3.0 Supports Low-Bandwidth Video and PTZ Camera Control
By Jim Bask
NewTek’s Network Device Interface (NDI) technology for IP video got another boost this week with the announcement of version 3.0, designed to improve the protocol’s performance with PTZ cameras on low-bandwidth networks.
The expansion of the protocol adds multicast with forward error correction, a new “high-efficiency” mode for full-resolution video called NDI HX, standardized PTZ camera control and tally, and improved encoding performance, NewTek said.
NewTek underscored the NDI v3 announcement with the introduction of a PTZ camera specifically designed to work with NDI HX. The NDI protocol allows video, audio, tally, camera control, and power all to be carried over one Ethernet cable…[continue reading]
