  • Macroblock level intrarefresh technique for encoded video
    Patent number: 6987805
    Abstract: A method is provided for encoding K>1 sequentially presented video pictures. Each of the K pictures is divided into an m>1 row×n>1 column array of non-overlapping coding units of equal sizes. Each coding unit occupies a respective coding unit position in the picture from which it was divided. An arbitrary, pseudo random pattern of coding units is selected for refreshing during each of the K pictures. Each pattern selected during any given one of the K pictures includes a sequence of one or more coding units of the array. In addition, the pixels of each coding unit selected for refreshing during a kth picture occupy different pixel positions than each coding unit selected for refreshing during a preceding one of the 1st to (k?1)th pictures of the K pictures. Furthermore, each pixel position of a moving picture image formed from the K pictures is selected for refreshing once over the sequence of K pictures.
