Abstract:
There are disclosed various methods, apparatuses and computer program products for video encoding. In some embodiments pictures are encoded into a bitstream. The bitstream comprises at least two scalability layers and pictures being associated with access units. A first indication and a second indication are encoded into the bitstream. The first indication is configured to indicate an output layer. And the second indication is configured to indicate at least one alternative output layer. A first picture of said at least one alternative output layer is output by a decoding process of the bitstream when no picture of the output layer is in an access unit containing said first picture of said at least one alternative output layer.

Claim (Index 5):
An apparatus comprising at least one processor and at least one memory, said at least one memory stored with code thereon, which when executed by said at least one processor, causes an apparatus to perform at least the following:\n encoding a scalable nesting supplemental enhancement information (SEI) message; associating the scalable nesting SEI message with a bitstream comprising at least two layers and with a first intra random access point (IRAP) picture within the bitstream; including a buffering period SEI message in the scalable nesting SEI message; indicating, in the scalable nesting SEI message, that the buffering period SEI message applies to more than one layer of the associated bitstream; indicating, in the buffering period SEI message, at least one buffering parameter applying when cross-layer random access skipped (CL-RAS) pictures of the first IRAP picture are not present in the bitstream, where CL RAS picture in a particular layer is a picture preceding, in decoding order, an IRAP picture in that particular layer from which the decoding of that particular layer can be initialized.
