Abstract
Methods and apparatuses provide real-time or near real-time streaming of content, specified in one or more playlists, using transfer protocols such as an HTTP compliant protocol. In one embodiment, a method can adaptively determine a minimum overlap for an overlap in time between two streams being received concurrently in order to determine when to switch between the two streams, and the minimum overlap can be determined based on connection speed. In another embodiment, a minimum playlist duration can be set as a multiple of a target duration which specifies a maximum duration of a media file specified in a playlist. In another embodiment, a method can enforce a start point for playback at a client device.
