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 instructions in the demuxing an mpts stream docid\ fil363whm6ibixibmn2fz section to add a pull stream in the zixi broadcaster navigation menu, click the inputs tab in the menu bar, click new input and then select the pull type the add a new input stream window is displayed new pull input 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 matrix docid\ bp6mo9f2qbxmu6gurkog4 ) default selected select the log this stream checkbox if you would like to generate event logs for this input select the analyze checkbox if you would like to enable stream analysis for the input specify the stream parameters (see input stream parameter table docid\ cz54cjse9z xsmvr2dhix ) 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 docid\ cz54cjse9z xsmvr2dhix below) if you want to enable time shift , select this checkbox (see input stream parameter table docid\ cz54cjse9z xsmvr2dhix ) the stream will be recorded and broadcast 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 docid\ cz54cjse9z xsmvr2dhix ) 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 docid\ cl1yd kuto1ozy0twvfda 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 described in the input stream parameter table below for more information, see encrypting an input stream in zixi broadcaster docid\ v3ryrbn08r4cojwl wvoq 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 at 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 the zixi broadcaster inputs ui input stream parameters table parameter description stream parameters remote host enter the ip address of the remote broadcaster server note that additional (failover) destinations can be added by clicking the adjacent “+” button you can specify up to 3 hosts remote port enter the port through which the broadcaster will pull 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 remote stream id 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 minimize latency when enabling this mode, the latency target will be adjusted down from the user setting to automatically find the lowest error free latency 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 docid\ zp5ql 5kthhdphmrhddhe 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 enable 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 unless encryption is added for more information, see decrypting an input stream in zixi broadcaster docid\ cl1yd kuto1ozy0twvfda 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 the stream encryption prevents any further processing, such as analysis, transcoding, etc the encryption works in the following way if the stream has been encrypted at the source the stream will remain encrypted regardless of the output type zixi broadcaster can only encrypt the stream after it has been decrypted if the stream is being encrypted by the zixi broadcaster it will be encrypted only if the output is a zixi pull or zixi push output all other outputs will send out an unencrypted stream for more information, see encrypting an input stream in zixi broadcaster docid\ v3ryrbn08r4cojwl wvoq 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

checkbox to clear out existing packets keep stream select this checkbox to insert on null packets and maintain pcr accuracy in cbr streams stream parameters reconnect on low bitrate select this option to automatically disconnect and reestablish a connection when experiencing low bitrate conditions this creates a "hard reset" to address unrecoverable congestion, clearing stalled buffers, and renegotiating path bandwidth bind to select from the drop down list the cidr that represents the ip range where the desired nic is accessed local port specify the port to listen on this port must be open on all firewalls between the zec and other devices it is communicating with stats history select this checkbox to record stream statistics high bitrate select this option to enable the broadcaster to handle streams up to 1gbps (e g , for jpegxs) must use by default, broadcaster auto detects dtls and uses it when available if it's not available, the stream falls back to clear/non
