A marker pointing to a precise time in the duration of a video. You can use cue points to trigger mid-roll ads.
When used for Dynamic Ad Insertion, the IMA SDK enables the player to request a video on demand (VOD) stream or live stream and send signals to Ad Manager for reporting. Event tracking with the SDK is more accurate than server-side beaconing.
Live linear video originates from broadcast television content, called analog. Before digital ads can be inserted into the content, the content must be converted into digital format to be viewable on IP-enabled devices.
Server-Side Beaconing (SSB)
SSB allows an HLS player to make a direct HTTP request to the Dynamic Ad Insertion (DAI) system, where Ad Manager tracks and reports on video stream metrics based on estimates. Any HLS video player should be able to play a SSB DAI stream, however the feature support is limited. As an alternative to SSB, applications can use the Google IMA SDK, which enables more features and more accurate reporting.
Video on demand
On-demand video may originate from broadcast television or digital content, but is already available in a digital format and can be viewed on IP-enabled devices.
