The switcher offers a variety of video and audio input/output ports, including 12G-SDI and HDMI 2.0 interfaces, facilitating sophisticated live productions.
Function Description:
The HS-4000 serves as a central control unit for video switching, allowing users to select video sources and transition them to air during live production. It supports various image effects such as Picture-in-Picture (PIP), Downstream Key (DSK), Luma Key, Chroma Key, Wipe Generator, still stores, and logo insertion. The Crosspoint Assignment (XPT) feature provides flexible I/O combinations by rerouting physical I/O ports to control panel buttons.
