Abstract:
1. A method of variable length decoding buffering, comprising: (a) providing first and second buffers, each of the buffers with a full/not-full indicator, and a position indicator indicating a position within the first and second buffers; (b) filling the first buffer with encoded bits when the full/not-full indicator for the first buffer indicates not-full and the position indicator indicates a position in the second buffer; (c) filling the second buffer with encoded bits when the full/not-full indicator for the second buffer indicates not-full and the position indicator indicates a position in the first buffer; (d) removing for decoding a group of bits in the first and second buffers starting at the position indicated by the position indicator and treating the first and second buffers as forming a single circular buffer; (e) updating the full/not-full indicators according to the bits removed by step (d); and (f) repeating steps (b)-(e).
