1. A method of processing encoded image data, the method comprising:
receiving an encoded bitstream comprising parameter set information including a syntax indicator, a first slice comprising first coded sample information for a first picture, a second slice comprising second coded sample information for the first picture, a third slice comprising third coded sample information for a second picture and a fourth slice comprising fourth coded sample information for the second picture;
responsive to detecting a first value of the syntax indicator, decoding the first coded sample information using a picture header syntax element from a first picture header of the encoded video bitstream; and
responsive to detecting the first value of the syntax indicator, decoding the second coded sample information using the picture header syntax element from the first picture header of the encoded video bitstream,
responsive to detecting the first value of the syntax indicator detecting that as error has occurred based on failure on detecting a second picture header associated with the second picture,
wherein the picture header is a NAL unit having a specific NAL unit type that indicates that the NAL unit contains picture header syntax elements.
