Segment types in video coding

An apparatus for decoding a coded picture of a coded video sequence comprising a first segment and a second segment, the apparatus comprising:

• at least one memory configured to store computer program code;
• and
• at least one processor configured to access the at least one memory and operate according to the computer program code, the computer program code comprising:
• first determining code configured to cause the at least one processor to determine a first decoding process for decoding the first segment, in which a first prediction is disallowed, based on at least a first syntax element of a high level syntax structure applicable to the first segment and the second segment, the first syntax element indicating that the first prediction is disallowed;
• second determining code configured to cause the at least one processor to determine a second decoding process for decoding the second segment, in which a second prediction different than the first prediction is disallowed, based on at least a second syntax element of the high level syntax structure, the second syntax element indicating that the second prediction is disallowed;
• first decoding code configured to cause the at least one processor to decode the first segment, based on the first decoding process in which the first prediction is disallowed;
• and
• second decoding code configured to cause the at least one processor to decode the second segment, based on the second decoding process in which the second prediction is disallowed.

A non-transitory computer-readable storage medium storing a program for decoding a coded picture of a coded video sequence comprising a first segment and a second segment, the program comprising instructions that cause a processor to:

• determine a first decoding process for decoding the first segment, in which a first prediction is disallowed, based on at least a first syntax element of a high level syntax structure applicable to the first segment and the second segment, the first syntax element indicating that the first prediction is disallowed;
• determine a second decoding process for decoding the second segment, in which a second prediction different than the first prediction is disallowed, based on at least a second syntax element of the high level syntax structure, the second syntax element indicating that the second prediction is disallowed;
• decode the first segment, based on the first decoding process in which the first prediction is disallowed;
• and
• decode the second segment, based on the second decoding process in which the second prediction is disallowed.
