Abstract
A method, apparatus and computer program product are provided to include information within a container that also includes a video bitstream as to whether individual image items corresponding to the video frames of the video bitstream bitstreams are self-decodable or, alternatively, are dependent upon one or more other image items. In an instance in which a respective image item is dependent upon one or more other image items, the method, apparatus and computer program product also include dependence information within the container identifying the other image item(s)upon which the decodability of the respective image item is dependent. As such, the method, apparatus and computer program product permit decoding relationships to be defined in the container between a predictively coded frame and other image item(s)upon which the predictively coded frame is dependent, thereby facilitating the decoding of the frame and, in turn, the video bitstream.
