Ad Insertion Files

Ad Insertion uses the following types of files:
File Description
pnad.log or pnad Advertising Presentation Log. Log file that chronicles all insertion and rotation activity performed by RealServer, including information related to ad clips and RealPlayer. For more details about this file, see RealServer Log Files.
ads.txt Lists ad files to play for a given content clip directory. RealServer rotates through this list. This file is also used to list content clips for Content Rotation.
Filename.rm The RealAudio or RealVideo content clip into which an ad is to be inserted.
Filename.rad Ad cue file. Lists the in-line Ad Insertion schedule for the companion content clip (.rm file). Filename must match the file name of the companion content clip. This file contains one or more timestamps and is used by RealServer to determine at what point in the content clip to insert an ad. For Content Rotation, this file is used to list the Content clip schedule.

The .rad file and ads.txt file must reside in the same directory as the content clip they reference, and the directory must be marked for Ad Insertion in the configuration settings file. The AdCfgList setting identifies which directories contain ads and what type of insertion (lead, end, or in-line) is to be used.

Ad Insertion Data Types

The RealServer can insert ads for RealAudio and for RealVideo data types.

Location of Advertising Media

Ad files that are to be inserted into the on-demand or live broadcast stream must reside on or be accessible by the RealServer that is broadcasting the featured content.

Bandwidth Negotiation

The Ad Insertion feature supports bandwidth negotiation. For information on bandwidth negotiation, see the RealAudio and RealVideo Content Creation Guide.
