  • Method and apparatus for adapting memory resource utilization in an information stream decoder
    Patent number: 6633608
    Abstract: A method and apparatus for reducing memory and memory bandwidth requirements in an MPEG-like decoder by preferentially allocating, in a first mode of operation, memory to an anchor frame storage functions and re-allocating, in a second mode of operation, some of the allocated memory to another function. The reduction image quality cause by the reduction in anchor frame memory is somewhat offset by a frequency domain CODE used in conjunction with the anchor frame memory in the second mode of operation.
