Systems and methods for signaling scaling window information in video coding
A device may be configured to signal scaling window information according to one or more of the techniques described herein.
1. A device for decoding video data, the device comprising one or more processors configured to:
receive a picture parameter set;
parse a first syntax element, specifying whether picture partitioning may be applied to a picture, in the picture parameter set;
parse a second syntax element, specifying whether reference picture list information is present in the picture header, based on a value of the first syntax element;
parse a third syntax element specifying whether weighted prediction information may be present in the picture header, in a case that a value of the second syntax element is equal to one; and
parse a fourth syntax element specifying whether quantization parameter delta information is present in the picture header, based on a value of the first syntax element.
2. A device for encoding video data, the device comprising one or more processors configured to:
signal a picture parameter set;
wherein the picture parameter set includes:
(i) a first syntax element, specifying whether picture partitioning may be applied to a picture;
(ii) a second syntax element, specifying whether reference picture list information is present in the picture header, in a case that a value of the first syntax element is equal to zero;
(iii) a third syntax element specifying whether weighted prediction information may be present in the picture header, in a case that a value of the second syntax element is equal to one; and
(iv) a fourth syntax element specifying whether quantization parameter delta information is present in the picture header, in a case that the value of the first syntax element is equal to zero.
3. A method for decoding video data, the method including:
receiving a picture parameter set;
parsing a first syntax element, specifying whether picture partitioning may be applied to a picture, in the picture parameter set; and
parsing a first syntax element, specifying whether picture partitioning may be applied to a picture, in the picture parameter set;
parsing a second syntax element, specifying whether reference picture list information is present in the picture header, based on a value of the first syntax element;
parsing a third syntax element specifying whether weighted prediction information may be present in the picture header, in a case that a value of the second syntax element is equal to one; and
parsing a fourth syntax element specifying whether quantization parameter delta information is present in the picture header, based on a value of the first syntax element.
