Title: SYSTEM AND METHOD FOR GENERATING A STREAM FROM INDEPENDENT NAL UNITS
Abstract:
In one embodiment, a method comprising obtaining a stream comprising first network abstraction layer (NAL) units generated in a first encoding, the first NAL units including first slices, obtaining second NAL units generated in a second encoding, the second NAL including second slice(s), and stitching the second NAL units into the stream, the stitching including positioning the second slice(s) in respective position(s) in the stream formerly occupied by temporary slice(s) generated in the first encoding, and for the second slice(s) conforming at least one slice header syntax element and at least one network abstraction layer unit syntax element of a second slice to values of a temporary slice formerly occupying the position of the second slice, and retaining at least one other slice header syntax element of the second slice as encoded in the second encoding.
