Abstract
State-of-the-art video coding schemes supports splitting a picture into smaller rectangular units called tiles units. Each tile units can be independently encoded and decoded by separate encoders and decoders, respectively. The primary purpose of tiles units is to allow parallel processing of the picture to reduce implementation cost and complexity. The present disclosure provides additional functionality to define flexible partitioned tile regions and to allow partial decoding and reconstruction of tile regions.
