Abstract
Receiving and processing out-of-band (OOB) data along with a media stream is disclosed. The received OOB data can be extracted from an OOB data stream and correlated with the media stream using timestamps. Display and other operations can then be performed when a timestamp of the OOB data matches a current timestamp of the media stream. In addition, timestamp notification requests can be received and processed such that when the current timestamp of the media stream matches a requested timestamp, a notification can be transmitted, and data can be received in response to the notification.
