A media device includes a processor and a memory coupled to the processor. The memory stores instructions corresponding to an overlay application and a media playback application. The instructions are executable by the processor to perform various operations. The operations may include obtaining media content identified in a manifest and using the media playback application to generate a display that includes the media content. Responsive to a trigger in the manifest, the operations also include retrieving the overlay application from the memory and executing the overlay application to allocate a portion of the display to interactive content indicated by the manifest.
