Media synchronization via image queue

This invention is directed to a system for processing media in an electronic device. An application operative to request the display of one or more graphics elements may be implemented on the electronic device. The application may identify graphics elements for display and organize the graphics elements in a layer tree for processing and display by a render server (e.g., a core animation render server). To coordinate the processing of graphics elements of the application or of several applications, the electronic device may include a media server operative to receive media from the application and generate an image queue that includes video frames of the media. The render server may associate a slot ID with each image queue, while the media server may provide the slot ID to the application for inclusion in the layer tree. When the render server reaches a slot ID in the layer tree, the render server may identify and display the associated image queue.
