Mediacast Output (NV-32-H)
The NV-32-H Mediacast Output component converts video from the HDMI 1 output into a Mediacast preview stream that can be displayed within any UCI. UCI Designers can drag the Media Display from the Mediacast Output component directly into their UCIs to create low-latency, 30fps video on their TSC-G3 devices. Since it uses the actual HDMI Output 1 as its source, users can trust it will match the HDMI output. If HDMI Output 1 is disconnected or invalid, the preview stream will be black or show an error screen. The Mediacast Output component is available on NV-32-H Decoders as well as Encoders whose HDMI Output Mode is set to “HDMI 1”.
AV Connection Requirements
The HDMI 1 output must be connected to an HDMI sink device (like a display) for video to be passed to the Mediacast Output Preview stream. Without this, the video will be black.
Note: Each NV Series HDMI output supplies up to 120mA on the +5v signal line.

When the Preview Stream is enabled, this control displays the URL for the Mediacast RTSP Preview stream.
RTP Address
When the Preview Stream is enabled, this control displays the multicast RTP address assigned to the Mediacast Output preview stream. This address comes from Core Manager’s Multicast Address range for Cameras.
