Abstract
Systems and methods to validate restriction event control streams sent to a video distribution system are provided. A particular method includes receiving a control stream from a content provider via a content proxy device. The control stream is associated with a restriction event and directs a media service delivery platform to associate a substitute service with a virtual network for at least one geographical region. The method also includes evaluating validity of the control stream based on content proxy information associated with the content proxy device.
