Abstract

One embodiment of the present invention relates to method where a syntax element is used to indicate if the tile information is the same for a sequence. The sequence is typically a bitstream for which one sequence parameter set (SPS) is valid. The syntax element can be part of the SPS or signaled such as in VUI or in an SEI message. Furthermore the syntax element can be a flag for example denoted tiles_fixed_structure_flag. The encoder decides how the pictures are divided by a tile structure enabling parallel encoding/decoding. When the same tile structure is used throughout a sequence information that the same tile structure is used throughout a sequence of the video stream is sent to the decoder according to this embodiment.
