Jctvc-l0227: vps_extension with updates of profile-tier-level syntax structure

A method programmed in a non-transitory memory of a device comprising:

• a. acquiring content;
• and
• b. generating a video parameter set of the content utilizing a level flag indicating a level within the content, wherein generating the video parameter set includes using a profile present flag, further wherein when the profile present flag is equal to 1, then profile information for a layer is present in a profile tier level syntax structure, and when the profile present flag is equal to 0, then the profile information for the layer is not present in the profile tier level syntax structure, further wherein when the profile present flag is equal to 0, then profile information for the layer is inferred to be equal to the profile information of the layer indicated by the profile reference layer number, further wherein when the level present flag is equal to 1, then level information for a layer is present in a profile tier level syntax structure, and when the level present flag is equal to 0, then the level information for layer is not present in the profile tier level syntax structure, further wherein the level reference layer number is equal to 0, level information for a layer is inferred to be equal to the level information of the layer indicated by the level reference layer number.
