  • Patent number: 10715808
    Abstract: Circuity for executing operations is provided. The operations divide a picture into tiles. The tiles are coded to generate pieces of coded data, each of which corresponds to a different one of the tiles. A bitstream is generated to include the pieces of coded data. In this regard, the coding of the tiles includes generating a first code string by: coding a first tile with reference to coding information of an already-coded tile neighboring the first tile when a boundary between the first and already-coded tiles is a first boundary; and coding the first tile without reference to the coding information of the already-coded tile when the boundary between the first and already-coded tiles is a second boundary. The bitstream is generated to include tile boundary independence information, which indicates whether each boundary between the tiles is one of the first and second boundaries.
