Steps

This document assumes you have implemented Digital Audio with Live AM/FM stream measurement with a "radio" content type. It outlines the new parameters you will use to implement podcast measurement.

Contact your Nielsen Account Representative to discuss the way you would like your podcasts reported (Classified)
Your TAM will provide new appIds for the applications that will offer podcasts
Update the parameters you use to call the SDK play and playheadPosition. Reference the appropriate Changes for Podcast Measurement below
Obtain Nielsen Podcast certification once your changes are complete and tested
Complete a Production License with your Nielsen Account Representative

Library

Use the same SDK library as Digital Audio, live AM/FM stream measurement.

Changes for Podcast Measurement

Initializing the SDK

Update your appid to the new ID provided by your TAM for podcast measurement. When you initialize the SDK, use 'dcr' in the sfcode instead of 'drm'.

play

Call play when the user taps the Play button to start the content.. The channelName parameter is not required.

play Example

{
   "channelName": "KABC-FM Morning Show"
}

loadMetadata

Use loadMetadata to pass information about your podcast to the SDK. The parameters must be passed as a JSON object.

    – (void) loadMetadata :(id)metadata;

Refer to loadMetadata for the list of parameters to be passed in the JSON object.

Note: The loadMetadata call after the first play call must have ‘content’ ("type": "content").

loadMetadata Example

{
  "type": "content",
  "assetid": "KABC:345-67483",
  "program": "KABC Morning Show",
  "title": "20171125: HR1",
  "length": "3600",
  "segB": "KABC-FM",                        // station call letters and band are optional here                   
  "isfullepisode": "y",
  "airdate": "20171125 06:00:00",
  "adloadtype": "2",
  "pipmode":"false" 
}

playheadPosition for "content"

You will continue to use playheadPosition to pass the position of the playhead while the content is being played; however, you will pass the relative position from the beginning of the file. This is different than live stream measurement, which uses the current Unix timestamp (seconds since Jan-1-1970 UTC).

Key	Description	Values	Required? (Y/N)	Example
On-Demand Audio	Position taken from beginning of the content in seconds.	Client-defined	Yes	Current player position from beginning of the content.

playheadPosition Syntax Example for iOS

    CMTime curTime=[player currentTime];
    long pos=CMTimeGetSeconds(curTime);
    [nAppApiObject playheadPosition:pos];

Usage Sequence and API The sample API sequence can be used as a reference to identify the specific events that need to be called during content and ad playback.

Action	Sample code	Description
Start of stream	`[nielsenMeter play: channelName];`	// channelName contains JSON metadata of program being played
Start of stream	`[nielsenMeter loadMetadata: contentMetadataObject];`	// contentMetadataObject contains the JSON metadata for the content being played
Listening	`[nielsenMeter playheadPosition: position];`	// playheadPosition is position of the playhead while the content is being played
End of Stream	`[nielsenMeter end];`	// Content playback is completed.

- Continue to call playheadPosition every two seconds until the user pauses, stops, or loses audio.

- Call a new loadMetadata when the user selects a different program.

With Preroll, Midroll, Postroll Ads Please note: The below examples include ad pod information. These ads are not ads served as part of the originator's programming (studio-recorded ads). These ads are hosted independently from the podcast content file.

When applicable, Playhead should be passed for the entire duration of ad pod, if the ad pod details are passed as part of loadMetadata.

Action	Sample code	Description
Start of stream	`[nielsenMeter play: channelName];`	// channelName contains JSON metadata of channel/video name being played
Start of stream	`[nielsenMeter loadMetadata: contentMetadataObject];`	// contentMetadataObject contains the JSON metadata for the content being played
Preroll	`[nielsenMeter loadMetadata: prerollMetadataObject];`	// prerollMetadataObject contains the JSON metadata for the preroll ad
	`[nielsenMeter playheadPosition: position];`	// position is position of the playhead while the preroll ad is being played
	`[nielsenMeter stop];`	// Call stop after preroll occurs
Listening	`[nielsenMeter loadMetadata: contentMetadataObject];`	// contentMetadataObject contains the JSON metadata for the content being played
	`[nielsenMeter playheadPosition: position];`	// position is position of the playhead while the content is being played
	`[nielsenMeter stop];`	// Call stop after the content is paused (ad starts)
Midroll	`[nielsenMeter loadMetadata: midrollMetadataObject];`	// midrollMetadataObject contains the JSON metadata for the midroll ad
	`[nielsenMeter playheadPosition: position];`	// position is position of the playhead while the midroll ad is being played
	`[nielsenMeter stop];`	// Call stop after midroll occurs
Content (End of stream)	`[nielsenMeter loadMetadata: contentMetadataObject];`	// contentMetadataObject contains the JSON metadata for the content being played
	`[nielsenMeter playheadPosition: position];`	// position is position of the playhead while the content is being played
	`[nielsenMeter end];`	// Called at the end of content
Postroll	`[nielsenMeter loadMetadata: postrollMetadataObject];`	// postrollMetadataObject contains the JSON metadata for the postroll ad
	`[nielsenMeter playheadPosition: position];`	// position is position of the playhead while the postroll ad is being played
	`[nielsenMeter stop];`	// Call stop after postroll occurs

Note: Each Ad playhead should reset or begin from 0 at ad start. When content has resumed following an ad break, playhead position must continue from where previous content segment was left off.

Nielsen Measurement Opt-Out Implementation

No changes are necessary because Opt-out implementation for podcasts is the same as live AM/FM stream measurement.

-== The Viewability Metric ==
-The viewability metric introduced in the Nielsen AppSDK represents the visibility of a video in the player along a playback. If you decide to implement the Nielsen Viewability Module, the SDK will track the viewability of the targeted player/element, log the viewable percentage, and record in seconds the time the player/element was in that viewable state.  Please refer to Implementing [[Implementing Viewability with AppSDK|Viewability with AppSDK.]]
-== Interruptions during playback ==
-As part of integrating Nielsen App SDK with the player application, the Audio / Video app developer needs to handle the following possible interruption scenarios:
-* Pause / Play
-* Network Loss (Wi-Fi / Airplane / Cellular)
-* Call Interrupt (SIM or Third party Skype / Hangout call)
-* Alarm Interrupt
-* Content Buffering
-* Device Lock / Unlock (Video players only, not for Audio players)
-* App going in the Background/Foreground (Video players only, not for Audio players)
-* Channel / Station Change Scenario
-* Unplugging of headphone
-In case of encountering one of the above interruptions, the player application needs to
-* Call [[stop]] immediately (except when content is buffering) and withhold sending playhead position.
-* Start sending pings – [[loadMetadata]] and [[playheadPosition]] for the new viewing session, once the playback resumes.
-Please see the [[Digital Measurement FAQ]] for more details
