Adding Pull Streams

Typically a Pull Stream is transmitted from another Zixi Broadcaster. In this case, the stream is initiated by your Zixi Broadcaster.

If the stream is an MPTS stream and you want to demux it into separate SPTS input streams, create the stream, by following the instructions below, and then follow the instruction in the Demuxing an MPTS Stream section.

To Add a Pull Stream:

In the Zixi Broadcaster Navigation menu, click the Inputs tab.
In the Menu bar, click New Input. The Add a new input stream window is displayed.
Enter the unique Stream I.D. for the Broadcaster.

Note this must be identical (case sensitive) to the stream name configured in ZEC.
Select the maximum concurrent connections to this stream from the Max. Outputs drop-down list. Default: Unlimited.

This setting can be modified without interrupting an existing stream.
Select the Show in Matrix check box to display this stream in the Matrix (see Using the Matri x). Default: Selected.
Select Pull for the input stream.
Specify the Stream Parameters (see Input Stream Parameter Table).
If you want to specify Billing Codes to identify and differentiate traffic on a Zixi Broadcaster for billing purposes, select this checkbox (see Input Stream Parameter Table below).
If you want to Enable time shift, select this checkbox (see Input Stream Parameter Table). The stream will be recorded and broadcasted after the specified delay. The time shift feature is typically used to broadcast a live event across time zones (due to the time differences between locations).
If you want to Enable multicast on pull outputs, select this checkbox (see Input Stream Parameter Table).
You can decrypt an encrypted stream as it enters the Zixi Broadcaster. To decrypt a stream, select the Decrypt Stream checkbox and fill in the parameters as described in the Input Stream Parameter Table below. For more information, see Decrypting an Input Stream in Zixi Broadcaster.
You can encrypt the stream as it enters Zixi Broadcaster. To encrypt the stream, select the Enable Encryption checkbox and fill in the parameters as describes in the Input Stream Parameter Table below. For more information, see Encrypting an Input Stream in Zixi Broadcaster
If you want to configure the Recording Parameters, specify them in the respective fields (see Input Stream Parameter Table).
Click OK. The “Input added” message appears on the top of the screen. The Push Stream from ZEC is added to the Zixi Broadcaster and now appears in the list of streams available in Zixi Broadcaster inputs UI.

Input Stream Parameters Table

Parameter	Description
Stream Parameters
Host	Enter the IP Address of the remote Broadcaster server. Note that additional (failover) destinations can be added by clicking the adjacent “+” button
Port	Enter the port through which the Broadcaster receives the stream from another Broadcaster server. Default: 2088 The default input port for Zixi Broadcaster is UDP port 2088. This port must be open on any firewalls between Zixi Broadcaster and other devices it is communicating with.
Stream	Enter the unique stream ID from another Broadcaster server.
Password (Optional)	If desired, enter the string for authentication. It must be identical to the string configured on the other Zixi Broadcaster.
Latency [ms]	Specify the maximum number of milliseconds that Zixi Broadcaster should protect the stream for. For example, 6000 milliseconds would ensure that the stream is protected for up to six seconds of delay in the network. This setting affects memory usage as higher levels of protection require more buffering. Default:6000.
Ignore TLS certificate error	Select this option when connecting to a trusted server that does not have a valid certificate. When this option is selected, Zixi Broadcaster will ignore the TLS certificate errors. This setting can be modified without interrupting an existing stream.
Bind to IP	Select from the drop-down list the local IP address to be used for this Input, OR select Any to enable any IP to be used.
Billing Codes	Billing codes are used to identify and differentiate traffic on a Zixi Broadcaster for billing purposes. When a billing code is added to a Source or Target, Zixi can track the traffic on that Broadcaster input or output separately from other inputs and outputs on the same Broadcaster. Billing codes are created by Zixi personnel on the Zixi Customer Portal for a particular organization.
Billing Code	Enter the billing code that corresponds to this stream. The relevant billing can be obtained from the organization that received the billing code from Zixi.
Billing password	Enter the password that corresponds to this billing code.
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 time of a delayed transmission of this stream. Maximum: 24 hours
*Enable multicast on pull outputs*	Select this checkbox to enables the transmission of this stream’s outputs as multicast. A Zixi Broadcaster 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. This setting can be modified without interrupting an existing stream.
Multicast-Only (for multicast enabled)	If desired, specify multicast-only outputs.
Decrypt stream	Select this checkbox to decrypt the Input stream. Please note that the stream will not be encrypted as it passes through the Zixi path. For more information, see Decrypting an Input Stream in Zixi Broadcaster.
Decryption type (for Decrypt stream enabled)	Specify the type of encryption that is being used in the stream. This setting can be modified without interrupting an existing stream.
Decryption key (for Decrypt stream enabled)	Specify the key for decryption. This setting can be modified without interrupting an existing stream.
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).
Encryption key (for Encryption enabled)	Click Generate to generate an encryption key. The generated encryption key must be sent to the end-user to decipher the received encoded stream.
*Recording parameters*	Select this checkbox to customize the recording parameters.
Destination Type	Select the radio button for the desired storage type and then fill in the relevant parameters. Record to disk – the recording is saved on the local disk. It is possible to record to an external destination by replacing the default storage location with a symbolic link. To learn more, see Using an External Storage section. Record to S3 – the file is saved to your AWS S3 Bucket. The mechanism uses AWS multipart upload. Amazon advises to define a lifetime rule for objects on destination bucket.
*Record to Disk Parameters*
File Name Template	Specify the file name pattern that Zixi will use to generate when saving the recorded content. A separate file will be generated for each recording up to the time specified in the Max recorded file duration parameter (see above). After this duration a new file will be generated. The file name pattern can include any string and up to five variables listed below. Only the %T=HH.MM.SS creation time is mandatory. You can change the order of these variables and add text as long as you maintain the legitimate structure of the file in Linux and Windows: %S=stream id - optional. %Y=year - optional %M=month - optional %D=day - optional %T=HH.MM.SS creation time - mandatory %U=YYYYmmddTHHMMSSZ UTC timestamp - optional For example, the following pattern %Y_recording%T.ts will generate the following file name 2017_recording15:32:35.ts.
Max recorded file duration [hours]	Specify the maximum time allotted for recording a video stream. Default: 2 hours
Keep recorded files for [hours]	Specify the maximum time for storing the recording. Default: 0 hours
Custom Path	Optionally specify a storage location for the recorded files that is relative to the root folder. This location bypasses the location specified as the root folder in the Settings > General screen.
*Record to S3 Parameters*
File Name Template	Specify the file name pattern that Zixi will use to generate when saving the recorded content. A separate file will be generated for each recording up to the time specified in the Max recorded file duration parameter (see above). After this duration a new file will be generated. The file name pattern can include any string and up to five variables listed below. Only the %T=HH.MM.SS creation time is mandatory. You can change the order of these variables and add text as long as you maintain the legitimate structure of the file in Linux and Windows: %S=stream id - optional. %Y=year - optional %M=month - optional %D=day - optional %T=HH.MM.SS creation time - mandatory %U=YYYYmmddTHHMMSSZ UTC timestamp - optional For example, the following pattern %Y_recording%T.ts will generate the following file name 2017_recording15:32:35.ts.
Max recorded file duration [hours]	Specify the maximum time allotted for recording a video stream. Default: 2 hours
URL	Specify the URL of the S3 bucket.
Ignore TLS certificate errors	TLS certificate for S3 bucket might be detected as faulty if bucket name contains dot[s]. When this option is selected, Zixi Broadcaster will ignore the TLS certificate errors and transmit the stream to its destination.
Access Key	The access key that is used for accessing the S3 bucket.
Secret Key	The secret key that is used for accessing the S3 bucket.
