Abstract: An electronic device with one or more processors and memory displays a first user interface including a plurality of audio tracks, detects a first user input selecting one of the plurality of audio tracks, and, in response to detecting the first user input, displays a second user interface for recording a video clip. The device also detects a second user input to initiate recording of the video clip and detects a third user input to stop recording of the video clip. The device further detects a fourth user input to publish the media item based on the video clip and the selected audio track and, in response to detecting the fourth user input, publishes the media item to a server, including sending to the server information identifying the selected audio track, the video clip, and information related to synchronization of the selected audio track and the video clip.

Abstract: An electronic device with one or more processors and memory detects a user input to play a media item, where the media item is associated with at least a portion of an audio track and one or more media files. The device requests the media item from a server in response to the user input and, in response to the request, receives, from the server, the one or more media files and information identifying at least the portion of the audio track. The device obtains at least the portion of the audio track based on the information identifying at least the portion of the audio track. The device also displays the one or more media files and, while displaying the one or more media files, plays back at least the portion of the audio track in synchronization with the one or more media files.

Abstract: An apparatus and method for data extraction from data units comprising a device for managing the extraction and determining if the data unit is of a predetermined type that a client desires to collect data from. The data unit types further comprising information fields which relate to data within the data unit wherein the information fields can be uniquely identified by a numeric tag. The numeric tag allows the apparatus and method to be dynamically modified by a user.
