Patent ID: 7415069

Claim:
A method for activating and deactivating parameter sets during decoding of a bitstream for display comprising the steps of: (A) storing a first picture parameter information set associated with a first identification value and a second picture parameter information set associated with a second identification value in a computer readable storage medium, wherein said first and said second picture parameter information sets comprise infrequently changing picture parameter information; (B) tagging said first picture parameter information set as active in response to a reference to said first identification value in a bitstream; (C) changing the tag of said first picture parameter information set from active to inactive and tagging said second picture parameter information set as active in response to a reference to said second identification value in said bitstream; and (D) tagging said second picture parameter information set as inactive and re-tagging said first picture parameter information set as active in response to a subsequent reference to said first identification value in said bitstream, wherein said first picture parameter information set and said second picture parameter information set are received in said bitstream prior to receiving said reference to said first identification value and said reference to said second identification value, respectively.
