Adding a Source - MPTS Multiplex

the mpts (multi program transport streams) multiplex source takes multiple spts sources and combines them to a single grouped feed with multiple video tracks a typical use case would be bundling a group of separate programs together to be distributed as cable channels for more efficient transmission the mpts should have a target bitrate that is higher than the sum of all of the effective bitrates of the individual streams included in the multiplex source the process involves selecting multiple sources from the list of existing sources each source will become a program in the mpts source you will need to name the program and can optionally specify a program number (by default the first program number is 0) this program number will be assigned to the program in the newly created mpts the following procedure describes how to add a multiplex source in zen master in addition, an explanation of each of the configuration parameters is given in the table below to add a multiplex source in the main navigation, click sources click + add the create new source selection window is displayed create source options click on mpts multiplex the create new mpts multiplex source window opens 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 creating a tag 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 maps 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 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 under sources , in the target bitrate (kbps) filed, specify the target bitrate for the multiplex stream in kbps the target bitrate number should be at least as high as the sum of all of the effective bitrates of the individual sources included in the multiplex source from the sources list, select the relevant sources to add them to the multiplex source and specify the following settings when they are added to the table below the selector in the program name field, enter a name for the program this overwrites any pre existing program name previously assigned to the stream in the program field, enter a program number for the spts source this overwrites any pre existing program number previously assigned to the source in the base pid , enter a base pid number for the stps source zixi will automatically assign new pid numbers for all pids in the spts stream with consecutive numbers following the base pid number based on this number 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 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 tr 101 290 technical report 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/cea 708 closed captions, select monitor cea 608/cea 708 checkbox monitoring cea 608/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 additional scte 35 options are available when you expand the scte 35 manipulation section here you can enable scte 35 insertion set the scte 35 pid remove any existing scte 35 messages from the stream replace any existing scte 35 messages with null 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 if you would like to adjust the advanced settings, click advanced the advanced settings fields are displayed advanced settings if you would like to track usage for
