This topic presents a list of chapter and/or segment data, including context data values, that Adobe collects via solution variables.

Table data description:

  • Implementation: Information on implementation values and requirements

    • Key - Variable, set either manually in your app, or automatically by the Adobe Media SDK.
    • Required - Indicates whether the parameter is required for basic video tracking.
    • Type - Specifies the type of the variable to be set, string or number.
    • Sent With - Indicates when the data is sent: Media Start is the analytics call sent on media start, Ad Start is the analytics call sent on ad start, and so on; the Close calls are the compiled analytics calls sent directly from the heartbeat server to the analytics server at the end of the media session, or the end of the ad, chapter, etc. The close calls are not available in network packet calls.
    • Min. SDK Version - Indicates which SDK version you would need to access the parameter.
    • Sample Value - Provides example of common variable usage.

  • Network Parameters: Displays the values that are passed to Adobe Analytics or Heartbeat servers. This column shows the names of the parameters that are seen in the network calls generated by Adobe Media SDKs.

  • Reporting: Information on how to view and analyze the video data.

    • Available - Indicates whether the data is available in reporting by default (Yes), or requires custom set-up (Custom)
    • Reserved Variable - Indicates whether the data is captured as an event, eVar, prop, or classification in a reserved variable.
    • Report Name - Name of Adobe Aanlytics report for variable
    • Context Data - Name of the Adobe Analytics context data passed to the reporting server and used in processing rules.
    • Data Feed - Column name for variable found in Clickstream or Live Stream data feeds
    • Audience Manager - Trait name found in Adobe Audience Manager
IMPORTANT
Do not change the classification names for any variables listed below that are described under Reporting/Reserved Variable as “classification”.
The media classifications are defined when a report suite is enabled for media tracking. From time to time, Adobe adds new properties, and, when this occurs, customers must re-enable their report suites to get access to the new media properties. During the update process Adobe determines whether the classifications are enabled by checking the names of the variables. If any of them is missing, Adobe adds the missing ones again.
