1. A method implemented by a decoder, the method comprising:
receiving a bitstream including a video coding layer (VCL) network abstraction layer (NAL) unit containing a slice of picture data divided into a plurality of tiles;
determining a number of entry points as one less than a number of the tiles in the slice, wherein the number of entry points is not explicitly signaled in the bitstream and is derived based on the number of tiles in the slice;
obtaining entry point offsets for the tiles based on the number of entry points; and
decoding a picture based on the entry point offsets.
