摘要： Systems and methods for encoding and decoding video data are disclosed. The method can include signaling in syntax information a picture parameter set (PPS) indicating a first tile size partition. The method can also include storing a plurality of tile size partitions and associated PPS identifiers (PPSID) in a database. If a second tile size partition for a second frame of video data is the same as a tile size partition stored in the database, the method can include signaling the PPSID for the corresponding tile size partition. If the second tile size partition is not the same as a tile size partition stored in the database, the method can include signaling a new PPS with the second tile size partition. The system can provide an encoder and a decoder for processing the video data encoded by the method for encoding video data.
