Source IP Address: For IP/UDP(MPEG2TS) input interface:
•
For unicast input there are two options
o
Without the raw socket mode enabled : set IP address to 0.0.0.0 or to the input IP of eth0
o
With the raw socket mode enabled : set IP address to the IP of the encoder (eth0)
•
For multicast input, set IP address to multicast IP address of the source to join
Raw Socket mode : Raw socket mode is not recommended for most applications . Without the Raw
Socket Mode enabled, the hardware NIC filters for the appropriate packets which is the most efficient
method. Raw socket mode sends all network traffic into the application level, and then packet filtering is
done at the application level which is less efficient.
WARNING: Raw Socket Mode can negatively impact the Ethernet bandwidth and is not recommended for
most installations. Please contact your CSI Digital support contact for further details and
recommendations for you particular installation.
Source port: For IP/UDP(MPEG2TS) input interface. Set to input stream port number.
Multicast IGMPv3 Source IP: For networks that require v3 IGMP multicast request/setup, enter the IP
address of the multicast source for your network.
SDP Server Address: For Native RTP input interface, a session description protocol file is required.
Enter the server URL and directory where the SDP file is located.
SDP Filename: For Native RTP input interface, enter the SDP filename.
RTCP For Native RTP input interface, enable RTCP time stamps if available from the source RTP
Audio Only This mode is available for MPEG2-TS input and output(via ASI or IP) If the incoming signal
has audio and video elements, then the video is removed and the output will only have audio element.
For an input with audio only, then the output is audio only.
HD-SDI or HDMI input mode: Select input resolution and frame rate from the pull down menu . If the
resolution/frame rate parameters are not set to match the incoming input signal resolution and frame rate
then xCoder will auto-detect the proper input resolution and frame rate. This will result in slower channel
start times since xCoder has to detect the input.
HDMI input does not support HDCP encryption
Repeat Last Frame when signal is missing: For HD-SDI mode only, this option can be enabled.
Disabled: when the HD-SDI input is removed or missing on a running channel, then the output of
the channel will stop. When the HD-SDI input is returned then the channel starts again.
Enabled : When the HD-SDI input is removed or missing on a running channel, then the output of
the channel will continue with the last good HD-SDI input video frame. It will appear as a frozen frame on
the output stream. This will remain frozen for a duration defined by the Frame Repeat Timeout parameter
Frame Repeat Timeout: When Repeat Last Frame when signal is missing is enabled, then this
parameter will control the duration that the last HD-SDI video frame is repeated. Set to 0 for infinite
repeat last frame, or a number other than 0 which will repeat the last frame for the value frame times. For
30 frame per second content, then value 30 would repeat for 1 second as an example.
