Abstract
This invention relates to a method of coding video data. The method comprising: determining a largest coding unit size for a picture; determining whether a largest coding unit within a picture is an intra type largest coding unit; and applying a partitioning to the largest coding unit based on whether the largest coding unit is an intra type largest coding unit.
Claims4
A method of decoding video data, the method comprising
- determining a largest coding unit size, by using a syntax element indicating a size of a largest coding unit for a luminance component;
- determining whether the largest coding unit is included in an I slice;
- and
- applying an inferred partitioning to the largest coding unit in the I slice, in a case that (i) the largest coding unit is included in the I slice and (ii) a flag indicates the largest coding unit is split into coding units with a predetermined size, wherein
- the flag is indicated using a sequence parameter set,
- the flag is a one-bit flag, and
- the inferred partitioning indicates to split the largest coding unit into luma samples having a size being smaller than a size of a largest coding unit included in a P slice or a B slice.
A device for decoding video data, the device comprising one or more processors configured to:
- determine a largest coding unit size by using a syntax element indicating a size of a largest coding unit for a luminance component;
- determine whether the largest coding unit is included in an I slice;
- and
- apply an inferred partitioning to the largest coding unit in the I slice, in a case that (i) the largest coding unit is included in the I slice and (ii) a flag indicates the largest coding unit is split into coding units with a predetermined size, wherein
- the flag is indicated using a sequence parameter set,
- the flag is a one-bit flag, and
- the inferred partitioning indicates to split the largest coding unit into luma samples having a size being smaller than a size of a largest coding unit included in a P slice or a B slice.
A non-transitory computer-readable storage medium comprising instructions stored thereon that, when executed, cause one or more processors of a device for decoding video data to:
- determine a largest coding unit size by using a syntax element indicating a size of a largest coding unit for a luminance component;
- determine whether the largest coding unit is included in an I slice;
- and
- apply an inferred partitioning to the largest coding unit in the I slice, in a case that (i) the largest coding unit is included in the I slice and (ii) a flag indicates the largest coding unit is split into coding units with a predetermined size, wherein
- the flag is indicated using a sequence parameter set, and
- the flag is a one-bit flag, and
- the inferred partitioning indicates to split the largest coding unit into luma samples having a size being smaller than a size of a largest coding unit included in a P slice or a B slice.
