Adding Push Streams

typically, a push stream is transmitted from zec in this case, the stream is initiated by zec while the zixi broadcaster remains in “listening mode” until the stream is initiated 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 push stream in the zixi broadcaster navigation menu, click the inputs tab in the menu bar, click new input and s elect push the add a new input stream window is displayed new push input enter the unique stream id 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 select the show in matrix checkbox 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\ rfirbtv4dlj vxosl4zab below) 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\ rfirbtv4dlj vxosl4zab below) if you want to enable time shift , select this checkbox (see input stream parameter table https //app archbee com/docs/m6zk9e4mypltlhci9hlkh/undefined#ybnna ) 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\ rfirbtv4dlj vxosl4zab ) 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 record the stream, you can configure the recording parameters (see input stream parameter table docid\ rfirbtv4dlj vxosl4zab ) click ok the “input added” message appears at the top of the screen the push stream from the zixi feeder/zec is added to the zixi broadcaster and now appears in the list of input streams available in the zixi broadcaster input ui input stream parameters table parameter description stream parameters password (optional) if desired, enter a password string to use for authentication (must be identical to the string configured in zec) this setting can be modified without interrupting an existing stream latency \[ms] specify the maximal latency that will override the latency that was defined in zec (in ms) default remote configuration (i e , use the latency that was set in zec) (see latency considerations docid\ c4fyn6 jleukjeugia2pr ) this setting can be modified without interrupting an existing stream point to point only this option is no longer supported disable p2p fallback selecting this checkbox will allow only p2p (disabling the option to re route traffic through the zixi broadcaster) id of high priority source this option is no longer supported 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] specify the time of the 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 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 selecting this checkbox will force the transmission of this stream only in multicast 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 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

advanced mode settings are generally intended for advanced users and special cases if you do not understand the settings, you should probably accept the default values advanced settings latency offset latency offset is a configuration parameter that delays the processing of a transport stream by a defined amount of time (in milliseconds) this delay is not arbitrary—it serves specific operational goals scte 35 cue injection and pre roll support in broadcast workflows, scte 35 markers signal ad breaks or content insertion points by applying a latency offset, the system can inject scte 35 packets ahead of playback , ensuring accurate timing for ad insertion or blackout triggers this is critical for compliance and monetization workflows example zixi broadcaster introduced latency offset to enable scte 35 insertion after the offset for pre roll scenarios stream normalization and timeline alignment hls inputs often arrive with irregular timestamps (pcr, pts, dts) or discontinuities adding a latency offset gives the system time to buffer and normalize segments , repair timeline irregularities, and remultiplex into a stable mpeg ts output this prevents audio drift and switching errors downstream smooth buffering for burst handling when upstream encoders send data in bursts, latency offset combined with buffering helps maintain a steady flow into the broadcaster this avoids jitter and packet timing issues that could disrupt adaptive bitrate workflows scte 35 parameters inject metadata select this checkbox to insert metadata into the stream support injection select this checkbox if you would like the stream to support scte 35 insertion scte 35 pid enter a pid number for scte 35 injection you can enter a value manually or use the up/down arrows that appear when clicking the field (or leave as auto to match existing scte 35 pid) remove old scte 35 packets if scte 35 injection is supported, select this checkbox to clear out existing packets timeout for number of ms to wait for a null packet to insert scte 35 (keeps the stream cbr) stream parameters id of high priority source if this stream will be used for failover in conjunction with another source, insert the id of the higher priority source stats history select this checkbox to record stream statistics allow enable arq to automatically detect lost or corrupted data packets and request their transmission options are remote configuration (default), on , and off enable multicast on pull outputs custom address select this checkbox to manually define a specific multicast ip address and port
