The camera stores the media it captures to SD or SSD storage on the product. When the mobile device wants to access the media, it needs to download it from the product over the wireless link between the product, remote controller and mobile device (depending on the product). Each media file captured by the camera can have several types of content associated with it including the full resolution media content, a lower resolution preview, a lower resolution again thumbnail, and custom data within the file's XML meta data. The full resolution content can take a long time to download over the wireless link, so it is often useful to download previews or thumbnails of many media files, and then only download the full resolution content of fewer select media files. This scheduler conveniently allows the small content types of media files (preview, thumbnail and custom data) to be downloaded to the mobile device. The scheduler can be used to queue and download content from a series of files, as well as used to re-prioritize files during the download process. The scheduler holds a list of pending tasks and it completes them one by one in first-in-first-out order. To prioritize a new task, moveTaskToNext can be used. Each task relates to a media file and can download multiple content types sequentially. When the last content type of a task starts being downloaded, the task is removed from the list. Note, the scheduler cannot be used to queue the download of full resolution media content. Only fetchFileData can be used for this.
