Abstract: Aspects of the disclosure provide a video decoding system. The video decoding system can include a decoder core configured to selectively decode independently decodable tiles in a picture, each tile including largest coding units (LCUs) each associated with a pair of picture-based (X, Y) coordinates or tile-based (X, Y) coordinates, and memory management circuitry configured to translate one or two coordinates of a current LCU to generate one or two translated coordinates, and to determine a target memory space storing reference data for decoding the current LCU based on the one or two translated coordinates.

Abstract: A method and apparatus for video encoding or decoding used by a video encoder or decoder respectively are disclosed. In one method, input data associated with a video sequence are received. A current sequence header for a current picture is determined. Whether the current sequence header corresponds to a first sequence header or a second sequence header is determined. If the current sequence header corresponds to the second sequence header, one or more syntax values of a syntax set associated with the first sequence header are assigned to corresponding one or more syntax values of the syntax set associated with the current sequence header. The current picture is then encoded or decoded according to the current sequence header.
