Introduction to Digital Rights Management - DRM

DRM Broadcast Monitoring

Broadcast monitoring is the process of receiving and reviewing media that is transmitted on a broadcast channel to determine if a particular media item has or has not been broadcasted. Broadcast monitoring may be performed to ensure an advertisement has been inserted on a broadcast television system as defined in an advertising agreement or broadcast monitoring may be used to ensure some media is not broadcast (e.g. licensed content). Broadcast monitoring typically involves scanning through a video or audio file for a watermark or other identifying characteristic.

Figure 1.22 shows how broadcast monitoring can be used to ensure that broadcast media is or is not broadcasted. This example shows that a studio uses a broadcast monitoring service to determine if media has been sent at a time when it is scheduled or if it is sent without proper authorization. The broadcast monitoring service or system provides a code to the studio that is embedded into the media that will be transmitted by a television station. The broadcast monitoring service or system has located one or several receivers in geographic regions where the television signals are broadcasted. These receivers forward the code(s) to the broadcast monitoring service which creates a report of the systems or geographic areas where the program codes have been detected.
