Stream Parameters

Card

select the available ASI card from the drop-down list. Only the physical ASI cards which have been installed on the machine will appear in the drop-down list.

Max bitrate

Specify the maximum expected bitrate for memory allocation. Recommended: 2X the actual bitrate, which will prevent buffer overruns (especially with VBR streams). Default: 8000.

Note – Overflows will typically occur when the Max Bitrate isn’t sufficient.

Read buffer

Specify the input read buffer to fill, before passing data to the application. Larger buffer size should be specified for higher bitrates; Smaller buffer size will be more responsive and smoother in lower bitrate streams.

Adjust by local time

Smoothing latency

The Smoothing feature uses a buffer to time packets according to the stream’s clock. This is useful when there are bursts in the rate in which the stream arrives. The smoothing features creates a queue in the buffer, allowing smoother entry into the Broadcaster. The Smoothing parameter defines the size of the buffer in Milliseconds. A larger buffer enables smoother entry, however, it may influence the latency rate.

Enable time shift

Select this checkbox to record the stream content and broadcast it after a specified delay. To deploy an input stream that uses the current stream’s time shift, you need to configure a “Delayed” input stream. (See Adding Delayed Streams).

Maximum delay [hh:mm:ss] (for Time Shift enabled)

Specify the maximum time delay of this input.

Enable multicast on pull outputs

Select this checkbox to enable the transmission of this stream’s outputs as multicast. A

Zixi receiver that will pull the stream will receive it in multicast. By default, Zixi Broadcaster is configured to allow transparent fallback to unicast if it is out of the LAN. Requires enabling Multicast Pull in the Settings.

Multicast - Only (for multicast Multicast enabled)Selecting this checkbox will force the transmission of this stream only in multicast

Select the check box to force only Multicast outputs.

Enable Encryption

Select this checkbox to encrypt the Input stream. For more information, see Encrypting an Input Stream in Zixi Broadcaster

Encryption type (for Encryption enabled)

Specify the type of Encryption (AES 128/192/256).
