Adding a Source - UDP/RTP

zen master can receive a source directly from a udp/rtp input when this method is used, the stream is not protected by the zixi protocol the udp streams can be one of the following types udp – plain udp rtp (real time transport protocol) fixes packet reordering (when possible) and supports use of fec (forward error correction) the following procedure describes how to add a udp/rtp source in zen master in addition, an explanation of each of the configuration parameters is given in the table below to add a udp/rtp source in the main navigation, click sources click + add the create new source selection window is displayed create source options click on udp/rtp the create new udp/rtp window opens new udp/rtp source in the info section, in the name field, enter a unique name to identify this source in the system in the tags field, select one or more of the predefined tags from the drop down list tags are used for access control by selecting a tag, you are relating this source to that tag tags are associated with certain roles (through the users & roles screen), and roles, in turn, are associated with users and user groups if you would like to create a new tag, see docid\ ypm9tw81ap6nq8stkv4rd in the events configuration profile field, select from the dropdown list the profile that you would like to apply to this source by default, the default profile is applied events profiles consist of a series of rules that determine precisely how various types of events are logged and what results they trigger the source's location is used to represent it in the proper position in the map display (see docid\ sfzm6jvorvuigo7x0dnue ) by default, the location is determined automatically based on the source's ip if you would like to manually set the location of the source (optional), use the following procedure click on the edit icon next to the location field a search box is shown below the location field enter identifying info for the location (e g street address, zip code, coordinates) search results are displayed below the search box as you type click on the desired location the selected location populates the location field in the udp/rtp configuration section, if your input stream uses rtp protocol, then select the use rtp protocol checkbox using rtp protocol fixes packet reordering (when possible) and supports use of fec (forward error correction) if you selected the use rtp protocol checkbox, then if you would like to use fec, then select the use forward error correction checkbox when fec is used, repair packets are sent on additional ports, enabling packet recovery if you selected the use rtp protocol checkbox, then if you would like to preserve the rtp headers (which include the timestamps and sequences) and propagate them the output, then select the preserve rtp headers checkbox if you would like to join a multicast group, in the multicast address field enter the multicast address the multicast address should be in the range of 224 0 0 0 239 225 255 255 if you entered a multicast address, then, in the source specific multicast field, you can specify a particular ip from which you will accept data in the port field, specify the port to listen on for the incoming content this port must be open on all firewalls between the ingest cluster and the input device in the max bitrate field, select from the drop down list the maximum bitrate for this source in the source configuration section, in the ingest cluster field, select from the drop down list one of the available ingest clusters as the destination for the source in the target broadcaster/s field, select your broadcaster preference either select a specific broadcaster to be used or specify your preference for using primary vs backup broadcasters, options are prefer primary broadcasters, primary broadcasters only, backup broadcasters only or prefer backup broadcasters for managed clusters, it is not recommended to select a specific broadcaster, as the broadcaster’s availability may not remain stable in the input nic field, if you would like to specify which nic is used, then select the ip of that nic from the drop down list by default, any is selected if you would like to apply a pid mapping profile to this source, then in the pid mapping profile field, select the desired profile from the dropdown list using this method creates a single source in zen master with pid mapping applied if you would like to maintain a source with the original pids and create an additional source with pid mapping (e g if you want to create several different pid mapped variations), then use the method described in docid\ gockl3upsd8v14ia2an6g to create a new pid mapping profile, see docid\ gftcayurpl7dinouyd14z select the alert on pid changes checkbox if you would like to generate email notifications whenever a pid change is detected select the log scte 35 checkbox if you would like to log scte 35 markers for this stream to log scte 35 markers, scte 35 needs to be enabled both on the ingest cluster and on the source configuration scte 35 logging is only available for v13 1 40262+ broadcasters if log scte 35 was selected, you can choose to receive alerts for scte 35 markers by selecting the enable scte 35 alerts checkbox additional scte 35 options are available when you expand the scte 35 manipulation section scte 35 manipulation here you can enable scte 35 insertion specify the length of a search window for a null packet for scte 35 intertion set the scte 35 pid remove any existing scte 35 messages from the stream see the parameters table below for an explanation of these options in the public output field, if you would like to allow access to the stream directly through a supported player, select the allow checkbox if you selected the allow checkbox, then enter a password in the password field to authenticate access to the stream under content analysis select one of the following options full select this option if you would like to enable full content analysis (cqa), including analysis of the stream's audio and video content, including audio levels, audio silence detection, frozen video detection, and more tr101 only select this option to perform tr101 analysis only (without video and audio content analysis) the analysis can be used to check the integrity of the ts and the most important elements of the stream the analysis includes priority 1 and 2 to learn more about tr101 analysis see https //www etsi org/deliver/etsi tr/101200 101299/101290/01 03 01 60/tr 101290v010301p pdf none no content analysis is enabled it is generally recommended to enable full content analysis unless it is causing technical problems if content analysis is disabled, the system won't detect errors in the video and audio content of the stream and won't generate warnings for such events if you would like to monitor cea 608 closed captions, select monitor cea 608 checkbox monitoring cea 608 closed captions requires using a version 14 4 or newer broadcaster if you would like to monitor cea 708 closed captions, select monitor cea 708 checkbox monitoring cea 708 closed captions requires using a version 14 4 or newer broadcaster if you would like to disable auto pull, select the disable auto pull checkbox disabling auto pull will lock channels using this source to the source's ingest cluster and targets to the source's current active broadcaster this setting only applies to pass through channels if auto pull is enabled , in the auto pull latency \[ms] field, specify the maximum latency for auto pull actions (default 1000 ms) in the webrtc playback section, select the desired playback method webrtc enables you to monitor the stream via web browsers and mobile applications with real time communication (rtc) webrtc needs to be activated independently for each source in zen master (by default it is disabled) select one of the following options disabled users will not be able to view this source using webrtc (default) pass through passes the stream through to webrtc without transcoding this option can only be used if the input stream is already in a webrtc compliant format (video h 264 codec with baseline or main profile and no b frames, audio opus codec) auto zen master automatically transcodes the stream using the optimal profile for each specific user in this option zixi broadcaster will decode the video, transforming it into raw frames, which will be passed to the webrtc library, where it will be re encoded for each individual user best quality however, if monitored by multiple users this can consume extensive resources 1080p/720p/480p/360p zen master transcodes the stream to a webrtc compliant profile with the specified resolution the transcoding is done by zixi broadcaster's transcoder this method requires a zixi broadcaster with x264 or nvidia for transcoding this method allows many users to monitor the stream without encoding separately for each individual user, which saves cpu capacity since there is only one stream version, it is recommended to encode to a low resolution and low bitrate so that the stream will be viewable by all users monitoring the stream in the initial state section, select the disabled checkbox if you would like to disable this source upon initial configuration select the muted checkbox if you would like to disable error/recovery notifications for this source upon initial configuration you can enable/unmute the source at any time under error concealment, click the enable error concealment checkbox to enable the following error concealment mechanisms that can correct trasnaport stream for downstream irds error concealment options 1 continuous timeline corrects errors that are related to timeline jumps in the source this mechanism will normalize the timeline by creating a variant of the input (the input is doubled) and normalizing the timeline of the doubled input 2 replace frames if there are frames with cc errors, it replaces them with skip frames (inserts the last good frame received in place of missing ones) this solves issues such as an ird that lost synchronization when it received broken frames this mechanism also creates a variant of the input (doubling the input) 3 renumber cc the continuity counter is part of the ts encapsulation when there are cc errors in tr101 analysis it means that the counter has a gap due to the lost frames this mechanism can re write the cc counter for the downstream devices, so they will see a continuous increase of the counter 4 delay (ms) enter the delay that the error concealment adds to the stream in miliseconds error concealment needs to buffer the stream to analyze it one second is a reasonable value lower values may cause the error concealment to not be able to fix some of the frames 5 cbr padding enter a value for the rate at which padding will be added to maintain a specific output transport bitrate for example, if you have a video bitrate at 5000 kbps or that varies from 3000 5000 kbps and audio at 64 kbps, total bitrate will be max 5064 kbps or min 3064 kbps with cbr padding set at 6000 kbps, 6000 kbps is being delivered downstream at all times, ensuring a consistent bitrate 6 pcr interval select the frequency at which program clock reference is inserted into the outputs transport stream this depends on standard used by downstream encoders or decoders options include atsc standard 100 ms dvb standard 40 ms see docid 9 olo1argk 2adoshyfbb for more information if you would like to adjust the advanced settings, click advanced the advanced settings fields are displayed advanced setting if you would like to track usage for this source, enter your billing code details see docid\ lalxj n928tegcpdpbirj in the auto pull
