Constrained Mode: UDP video for cellular/wireless networks. Check the box to enable constrained mode for
all the RTP over UDP video streams.
With H.264 (not MJPEG) UDP video, CohuHD supports a constrained mode of operation. Constrained mode
can greatly improve the reliability of a video stream over cellular and wireless/radio networks that are more
prone to network interruptions and may have smaller buffers for handling UDP video packets.
Check the box if you use a cellular connection.
M2TS Mode (MPEG2 Transport Stream): Check the box to enable M2TS Mode for both streams. When the
box is checked, the RTP/RTSP/HTTP/CohuMjpeg transport-based streaming for both the streams is disabled.
Because the M2TS packets include the information necessary for decoding the stream, no connection to the
camera (for the SDP file) is needed. You can pull the video packets directly off the network.
NOTE:
•
The Helios Viewer and IE (CohuHD ActiveX control) do not support this streaming mode.
•
Once enabled all other modes of streaming are disabled. You will need to disable the M2TS stream
to re-enable the RTSP media server on the cameras.
For more information on Constrained and M2TS Modes see Video Streaming Protocols white paper at
CohuHD website: http://cohuhd.com/Files/white_papers/CohuHDVideoStreamingProtocolsWhitePaper.pdf.

Video Format:
The resolution for the second stream can be selected at different resolutions and aspect ratios. Resolution
and frame rate of stream 2 are equal or lower than stream 1.
Max Packet Size: The factory default is 1400 bytes. For 10BASE-T networks use 550 bytes, 100BASE-T use
1400 bytes, and 1000BASE-T (GigE) with jumbo frame support use 8192 bytes.
