Abstract
A video coding mechanism is disclosed. The mechanism includes receiving a bitstream comprising a slice. A number of entry points (NumEntryPoints) in the slice is derived. Offsets for subsets of coded slice data with subset index values ranging from zero to the NumEntryPoints are determined. The slice is decoded based on the offsets for the subsets of the coded slice data. The slice is forwarded for display as part of a decoded video sequence.
Claims20
A method implemented by a decoder, the method comprising:
- receiving, by a receiver of the decoder, a bitstream comprising a slice;
- deriving, by a processor of the decoder, a number of entry points (NumEntryPoints) in the slice;
- determining, by the processor, offsets for subsets of coded slice data with subset index values ranging from zero to the NumEntryPoints;
- and
- decoding, by the processor, the slice based on the offsets for the subsets of the coded slice data.

A method implemented by an encoder, the method comprising:
- obtaining, by a processor of the encoder, a reference slice of a coded reference picture;
- deriving, by the processor, a number of entry points (NumEntryPoints) in the reference slice;
- determining, by the processor, offsets for subsets of coded data in the reference slice based on the NumEntryPoints;
- decoding, by the processor, the reference slice of the coded reference picture based on the offsets for the subsets of the coded data in the reference slice;
- encoding, by the processor, a current slice into a bitstream based on the reference slice;
- and
- storing, by a memory coupled to the processor, the bitstream for communication toward a decoder.
