The Datazoom Ad Framework Data Dictionary defines the events, metadata, and fluxdata associated with advertising playback within the media player (i.e., when Media Type equals “ad”).

Designed for Datazoom Application Collectors configured with both Media Player and Ad Framework Extensions, this dictionary automatically tracks the user's interaction with ad breaks—including pre-roll, mid-roll, and post-roll scenarios.

Key Features:

Ad-Specific: These data points are distinct from the Media Player Data Dictionary; they specifically monitor ad performance and ad-related user behavior.
Configurable: Collection of these ad events can be enabled or disabled via the Datazoom Console without changing your code.
Extensible: As with other dictionaries, the Datazoom SDK allows for the collection of unlimited custom events and metadata alongside these standard ad metrics.

Events

Discrete occurrences driven by user interactions or system actions

Metadata

Attributes describing the context of an event

Ad

Fluxdata

Metrics measuring changing parameters over time

Supported Collectors	2
Supported Media Types	Ad
Notes	For the HTML5 collector, this is currently only supported by Safari.

Beacon Response

ad_beacon_response

Fired whenever a beacon delivery response was received. This event can include (if selected) three ad metadata data points: ad_beacon_status (e.g., 200) ad_beacon_type (e.g., “impression”) ad_beacon_url

Supported Collectors	2
Notes	Fired whenever a beacon delivery response was received. This event can include (if selected) three ad metadata data points: ad_beacon_status (e.g., 200) ad_beacon_type (e.g., “impression”) ad_beacon_url

Buffer End

buffer_end

When media plays after Buffer Start or when the player state changes during buffer due to user action or an error.

Supported Collectors	23
Supported Media Types	Ad
Notes	A buffering event has just completed. The player fires this event which returns a value of 1 to indicate that playback has resumed.

Buffer Start

buffer_start

When the player has to wait for the video buffer to fill with video segments.

Supported Collectors	23
Supported Media Types	Ad
Notes	When the Buffer Start event is thrown and a value received, it is correlated to a specific playback time by comparing it to the playback length within the manifest. Once the Buffer End event has thrown, the delta between the two can be used to forensically analyze a series of chunks to determine the veracity of the content files. If the issue is corrupt chunks, a new encode can be produced.

Error

error

This event fires if a error causes content or ad playback or retrieval of the video to fail.

Supported Collectors	35
Supported Media Types	Ad

Media Loaded

media_loaded

Triggered when player is ready to begin playback after playback is invoked.

Supported Collectors	34
Supported Media Types	Ad

Media Object Request

media_object_request

Fired after the player has requested an object related to video playback. This object may be a manifest, audio / video segment or subtitle file. The player will fire this event after the full roundtrip of request and response has completed.

Supported Collectors
Supported Media Types	Ad
Notes	Primarily intended for open tracing via CMCD.

Media Request

media_request

When media type is 'content', this is triggered when media_request is invoked. This could happen automatically in auto-play situations or when a user presses the play button. When the media type is 'ad', this is triggered when VAST request is made.

Supported Collectors	25
Supported Media Types	Ad
Notes	Identify problems that may be occurring in the video player which prevent successful playback after a user requests playback.

Milestone

milestone

When the playhead position plays through a customer configurable percentile milestone of the video's duration (seeking through the milestone does not trigger the event). The event fires no more than once for each percentile milestone per ad session.

Supported Collectors	43
Supported Media Types	Ad
Notes	Configure milestones by visiting your collector configurations pages from the Collectors page, scroll to the Milestones setting in the Event Control section. By default, for content, milestones fire when the user passes 5%, 10%, 25%, 50%, 75%, 90%, & 95% point in the content playback timeline and, for ads, when the user passes 25%, 50%, & 75% point in the ad playback timeline.

OM Session Created

ad_om_session_created

Fired when the client is able to create an OM ad-session for the ad, which means that at least all the prerequisite for OM are in place. This event can include (if selected) one ad metadata data point: ad_om_session_data (prerequisite resources for OM)

Supported Collectors	2
Notes	Fired when the client is able to create an OM ad-session for the ad, which means that at least all the prerequisite for OM are in place. This event can include (if selected) one ad metadata data point: ad_om_session_data (prerequisite resources for OM)

OM Session Omitted

ad_om_session_omitted

Fired when the client is unable to create an OM ad-session for the ad. This may be an issue or an expected result. This event can include (if selected) metadata data points: ad_om_session_data (prerequisite resources for OM) error_msg (reason the OM session was omitted - such as “Resources not found" or “Unsupported”.)

Supported Collectors	2

Pause

pause

When playback is intentionally halted.

Supported Collectors	41
Supported Media Types	Ad

Playback Complete

playback_complete

When the video player reaches the end of the currently playing content. The event can be triggered multiple times if the user reaches the end of the currently playing content, scrubs back and then reaches the end of the content again.

Supported Collectors	45
Supported Media Types	Ad

Playback Start

playback_start

When the video starts playing for the user, also known as "first frame".

Supported Collectors	46

qualified_view

When playback duration surpasses customer configurable thresholds of time in seconds.

Supported Collectors	46
Supported Media Types	Ad
Notes	Configure qualified view thresholds by visiting your collector configurations pages from the Collectors page, scroll to the Qualified View setting in the Event Control section. By default, for content, qualified view thresholds are 30 seconds and 60 seconds and, for ads, the qualified view threshold is 5 seconds.

Rendition Change

rendition_change

When the player's Adaptive Bitrate Streaming upshifts or downshifts during playback to a different quality level available in the manifest. This event includes absShift attribute identifying the direction of the change.

Supported Collectors	10

Resume

resume

When the user begins playing again after pausing the video during playback.

When there is an unexpected playback interruption because the buffer has been depleted.

Supported Collectors	12
Supported Media Types	Ad

Stop

stop

Triggered when: 1. A playback error results in the termination of content playback. 2. The context (or the logical equivalent) corresponding to a specific player is destroyed: 2(a). The application may destroy the context when playback is stopped by the user. 2(b). The application may destroy the context after playback has reached the end of content (and the player isn’t going to be reused any further). 2(c). The collector (in certain cases) may be able to detect when the application is terminated (e.g., user closes the browser tab) and destroy all player contexts automatically. 3. If a change in the content URL is detected by the collector, a new content session should begin and a `stop` event should be triggered for the previous content session.

Supported Collectors	3
Supported Media Types	Ad
Notes	Notable condition where the `stop` events is not triggered: When playback reaches the end of the content timeline (i.e., the same condition for triggering `playback_complete`), the content session remains open, unaffected by the fact that playback has reached the end of content so if post-roll ads are played or play-head is rewinded afterward, the subsequent events belong to the same content session.

When the user enables or disables subtitles or closed captioning.
