Refer to the Console Guide > Server-Side Ad Insertion to complete the StreamPackage configuration. The advanced settings are described as follows:
SCTE-35 ad message type
StreamPackage SSAI allows only recognizing specified types of SCTE-35 markers as ad markers for processing, and other types of markers will be ignored. The service will parse the SCTE-35 information in the ad marker (such as the base64 in the HLS SCTE-35 Enhanced type ad marker) to obtain its type. The specific steps are as follows:
1. In Advanced Settings, set the SCTE-35 ad message type to SCTE-35 enhanced. Then Ad triggers and Ads on delivery restrictions settings will appear;
2. In Ad triggers, select the types you need, which can be multiple selections. Following eight types are supported: Splice insert, Provider advertisement, Distributor advertisement, Provider placement opportunity, Distributor placement opportunity, Break, Provider overlay placement opportunity, Distributor overlay placement opportunity;
3. In the Ads on delivery restrictions, select the restriction type, which is single selection. Options include: None, Restricted, Unrestricted, Both.
Ad marker passthrough
StreamPackage SSAI service supports configuring whether ad markers appear in the output manifest.
When the Ad marker passthrough is set to StreamPackage default, the ad markers in the input manifest will be passed through even if ad replacement has been performed.
Slate ad
In the Personalization details configuration section, StreamPackage SSAI service supports configuring slate ad and maximum threshold for unfilled ads. This configuration is only used for live streams.
Slate ad: a slate ad is a default on-demand video. When the ad duration returned by the ad decision server is insufficient, StreamPackage will loop the slate ad after the personalized ad to maintain a stable live stream duration.
Maximum threshold for slate ad: by configuring the Personalization threshold, you can control the maximum duration of slate ads. If the personalized ad duration is too short and the required slate ad exceeds the threshold, the ad replacement will be canceled, and the source stream will be played directly.
CDN content segment prefix
When configuring the source stream CDN prefix, StreamPackage will use this prefix to replace the prefix filled in the content source when stitching the back-to-origin manifest request. And in the replaced manifest, add this CDN prefix to the URL of the source stream content segment.
When the player initiates a request to the replaced source stream segment URL, it can directly back to the source through this CDN.
The configuration process is as follows:
1. Configure the domain name at the CDN to map the CDN domain name to the source stream;
2. In the StreamPackage Ad insertion configuration, fill in the CDN domain name in the CDN content segment prefix.
