Introduction

 

This document is a guide on how to use the ISAACPlayer24H Module in PIXERA. The Module integrates Smart Monkeys's ISAAC management system into PIXERA.

The Module supports three modes, please note this documentation covers only those versions of the Module that use a single 24 hour timeline. Versions before 0.9 used two main timelines that covered dynamically assigned time periods. That approach is deprecated.

 


 

First Mode: Calendar

 

In the first mode, the Module builds a timeline based on an ISAAC schedule. The timeline is 24 hours long and is kept in sync with the current time of day, i.e. time zero on the timeline corresponds to midnight (12 AM). After 24 hours the timeline loops. 

Every 30 seconds, the Module checks ISAAC for new data. Media files are checked first. If new files are needed the downloader stores them on the hard drive. PIXERA then distributes the files to the clients as configured in the resource distribution settings.

Next, a schedule is pulled from ISAAC. The schedule contains ISAAC playables, i.e. media and/or compositions, that are to be played at a certain time. The Module moves through the schedule from the current time up to a set number of future entries and creates clips at the right points in time using resources that refer to the media specified in the schedule.

In the following update cycles, media files which are no longer needed are removed, new ones are added, and the clips in the timeline are updated accordingly. 

 


 

Second Mode: Loop

 

The second mode is ISAAC's loop mode. In this mode a single playable is placed on the timeline for the whole 24 hours.

 


 

Third Mode: Instant Play

 

The third mode is called “instant play.” It can be used in combination with either of the other two modes. In this mode, playables marked as available for instant play are downloaded in the background. When instant play is triggered in the ISAAC UI the playable is placed on a second timeline. This timeline is pushed into the foreground and played when in use.

Be aware that downloading the media can take some time. The mode is instant in the sense that it is not based on a schedule. However, the fact that it may take time for the media to be available on disk may cause delays.

 


 

First Steps in ISAAC

 

  1. Settings 
    1. Modules
      1. Register Module PIXERA fleet
        1. Add player to the Fleet
        2. The Module ID is used to establish the communication between PIXERA and ISAAC
        3. Select the mode
      2. Players
        1. Mark media for Instant Play (optional)
      3.  Templates
        1. Add Composition Templates (optional)
  2. Media Manager
    1. Upload media.
    2. Mark media for Instant Play (optional)
  3. Schedule Editor
    1. Create Playlists/Blocks and a Schedule

 


 

First Steps in PIXERA

 

  1. If the Module was not pre-installed with your version of PIXERA, then import it by using the plus button at the bottom of the Library subtab.
  2. Add the Module to the PIXERA Control workspace by dragging it from the Library subtab.
  3. Edit the Module's startup settings so that it can connect to ISAAC and has the correct media download folder.
  4. Create or rename a timeline so that it matches the property in the Module (see below).
  5. If using instant play create a second timeline and give it a name that matches the property (see below).
  6. Initialize the Module by running the init() action. This automatically creates the layers needed to hold generated clips.

Configure the layers for output by relating them to screen perspectives and ensuring that the screens are mapped correctly to the outputs (as far as mapping and rendering is concerned the layers do not differ in any way from standard PIXERA layers).

 


 

Updating the Module

 

If the Module is preinstalled, your new PIXERA installer may also include a new version of the Module. If not, then manually update the Module in the library:

  1. Library
    1. Select the Module
    2. Right click Show In Explorer
  2. Replace the Module's content with the content from the zip

When the Library is up to date (new installer or manual update) update the instantiated Modules:

  1. Update
    1. Right click on the Module's header
    2. Update From Library
    3. Click Ok
    4. Repeat for all Isaac Player Modules
  2. Older PIXERA versions may require a reset to the Aux directory
    1. Right click on the Module's header
    2. Click “Store in Own Aux Directory”, if it is available

 


 

Web UI

 

The Module has a Web UI that allows basic operation via a simple interface and provides an overview of the Module's state. 

  • Start / stop button. Runs the init() and uninit() actions.
  • ISAAC status indicator. This is green if the Module is regularly receiving heartbeats from the ISAAC server meaning that schedule processing is possible in principle.
  • Name of the Module.
  • Enable or disable maintenance mode.
  • Log window for status information and important errors.
  • Status of the main timeline. This includes progress of the current playable and the current transition.
  • Status of instant play.
  • System load statistics.

 

 


 

Tips for Common Use Cases

 

  • Enable the “Auto Init” property in the Module to ensure continued operation after changes to the system. 
  • PIXERA Resource Distribution Settings
    • Enable the “Transfer Resource on Import” property to ensure that importing a resource via ISAAC will automatically trigger distribution to all clients.
    • Adjust the cache settings so that the clients playing out media can cache the files locally.
  • Activating “Follow Nowpointer” in the timeline's button bar makes it easier to keep track of timeline changes near the currently visible timeline position. 
  • Using Multiple ISAAC Modules in Parallel
    • Each Module must refer to its own set of timelines (Modules can not share timelines).
    • Each Module must have its own resource folder and on-disk download directory.
  • Disable Pixera Fileversioning to pervent playback errors with accidentally versioned resources

Compositions

 

Compositions allow multiple files to be assigned and positioned within one playable. The Module will create layers to represent them when they are shown at the same time.

To create a composition definition use the composition editor in the templates section of the management console for PIXERA Media Players in ISAAC. 

Example of a composition template: 

[

The Functionality of the objects in this json depends on the id and on the type.

The id is divided into 3 parts separated by “_”.

  • Tag
    • med
      • Mediaselector
      • Main media.
      • The name of the Layer is “displayName”
    • tri
      • Mediaselector
      • Transition In media.
      • The name of the Layer is “displayName”.
      • This media is placed as a transition (overlapping the main media) from the previous playable to this playable, when no conflict with the transition out of the previous playable occurs or the transition collision behavior is set to “Force In”.
    • tro
      • Mediaselector
      • Transition Out media.
      • The name of the Layer is “displayName”.
      • This media is placed as a transition between (overlapping the main media) from this playable to the next playable, when no conflict with the next transition In occurs or the transition collision behavior is set to “Force Out”.
    • trc
      • Combo
      • Transition collision behavior
      • Force In or Force Out
    • ccs
      • Combo
      • Custom content media (Live input, browser,…).
      • The name of the layer is “displayName”.
      • The options are equal with the name of the custom content.
      • To ignore the custom content select “None”.
    • ccd
      • Duration 
      • Custom content duration
        • If the duration is 0 the duration of the whole playable/ composition will be used.
        • If a duration is set, the duration willl be applied. No range check is done.
      • "ignoreDuration": true
        • When not set to true the duration will be added to the whole playables duration.
  • Number
    • 3 digits
    • Ids with the same number are tied together
      • tri, tro and trc with the same number are describing the same transition and its behavior.
      • ccs and ccd with the same number are describing the same custom content and its duration.
  • Iid
    • Unique id
    • The id must be unique between all transition templates
      • Unique in a single template
      • Unique between all template

It is possible to create compositions with multiple groups of custom content or media with transitions und connect them with different numbers. Be aware to use different layers by using different display names.

 


 

Automatic Audio

 

When enabled, the Module pulls all audio files matching the defined audio extensions. When a playable with a matching video extensions is found, the Module checks for a corresponding audio file, by comparing the filename. When found, the audio file is placed on the specified audio layer.

 


 

Variables 

 

Variables can be created and removed in the properties. Actions for these variables are created and added into variables folder of the Module. This actions can be triggered with an external function call or by connecting with an other action and using callers. When the variables are executed, the value is sent to Isaac. 

After updating the Module use “Rebuild Variables” to make them available again.

 


 

Content Management

 

Integrated ISAAC Downloader.

The ISAAC downloader is bundled with the Module. It downloads and (when enabled) deletes unused media. This includes downloads for instant play.

 


 

Timecode

 

The main timeline can be set to use timecode. Enable this in PIXERA (in the Audio settings for LTC, in the SMPTE (USB) settings for timecode via USB interface as well as in the timeline inspector). The timecode must run from 0 to 24 hours.

The expert property “Enable Timecode” allows pausing the timecode chase when using the play, pause and stop actions (ISAACPlayer.Player). The timecode configuration is still active, but the timeline ignores the input when paused or stopped. Without this setting enabled it would not be possible to stop the timeline because it is locked to timecode. Play will continue the timecode chase again.

 


 

Stop/Pause Timelines

 

Use these actions for pausing, stopping, and playing the timelines. This can be used when the ISAAC Module should be bypassed. Like mentioned in the entry on timecode, this temporarily disables timecode chase and therefore allows the Module to be stopped.

 


 

Maintenance Mode

 

Can be activated in the web interface. The communication with the ISAAC instance is disabled until reenabled or the “Max Maintenance” has been reached. While in maintenance the ISAAC host can be updated without interrupting the playback, but only if the timeline has been build before.
