US 7839930 B2
The value of the “numref” field in the field header of the P-field of the entry I/P-frame shall be the binary value “0”.
The value of the “reffield” field in the field header of the P-field of the entry I/P-frame shall be the binary value “0”.
Following the entry I-field of the P/I frame, a P/P-frame in field interlace mode shall be present in the bitstream before any occurrence of P-frames in progressive or frame interlaced modes.
The value of the “numref” field in the field header of the first P-field following the entry P/I-frame shall be the binary value “0”.
The value of the “reffield” field in the field header of the first P-field following the entry P/I-frame shall be the binary value “0”.
Any B-frames following the entry P/I-frame in the bitstream and for which the presentation time comes later than the presentation times for that entry P/I-frame shall not be encoded as depending on the P/I-frame.
The first (in temporal order) B-field of any B/B-frames following the entry P/I-frame in the bitstream and for which the presentation time comes later than the presentation times of that P/I-frame shall not be encoded as depending on the P-field of the entry P/I-frame.
