Abstract:
1. A method of preparing a 3D media stream such that long jumps do not result in buffer underruns, comprising: a) receiving a 3D media stream; b) dividing the 3D media stream into a set of base view blocks and dependent view blocks, each pair of base view block and associated dependent view block constituting a 3D block; c) for a first base view block, employing at least a local bit rate in a calculation to determine if a long jump during 2D playback may be made to a second base view block without the occurrence of a buffer underrun; d) for a first 3D block, employing at least a local bit rate in a calculation to determine if a long jump during 3D playback may be made to a second 3D block without the occurrence of a buffer underrun; e) if a long jump may be made to the second base view block and 3D block without the occurrence of a buffer underrun, then configuring the media stream to allow long jumps following the first base view block; and f) creating a file system image or master disc image from the divided and configured media stream.
