Abstract: Systems and methods are described herein for cataloging user-generated content. In one embodiment, user-generated content is received, and metadata associated with the user-generated content may be captured. The metadata may be automatically analyzed to determine one or more common characteristics of the user generated content.

Groupings of user-generated content may be defined based on the common characteristics. Post-processing and file storage operations may be performed on the user-generated content associated with a grouping. Groupings may be selected for playback and the user-generated content may be streamed to a target device.

Abstract: System and methods for selecting one of the alternative streams of encoded media from a group of alternative streams of encoded media for use during start-up of playback of the encoded media in accordance with embodiments of this invention are disclosed. The systems and methods begin by determining an estimated stability period for a current bandwidth of a communicative connection between the playback device and a remote system providing the alternative streams of encoded. A test process is then performed on the streams of encoded media to select one of streams of encoded media that provides portions of said encoded media such that an underflow condition does not occur during the estimated stability period. The streaming of encoded media is then commenced by requesting the portions of encoded media be transmitted from the remote server using the selected stream.
