1. the method that speed is adjusted, the method comprises:

  • System bits is staggered;

    The first parity bit stream is staggered;

    The second parity bit stream is staggered;

    In the situation that the figure place of staggered system bits, staggered the first parity bit stream and staggered the second parity bit stream is not more than virtual buffer, described staggered system bits, described the first staggered parity bit stream and described the second staggered parity bit stream are buffered in described virtual buffer;

    In the situation that the figure place of described staggered system bits, described the first staggered parity bit stream and described the second staggered parity bit stream is greater than described virtual buffer, described the first staggered parity bit stream and described the second staggered parity bit stream are carried out to first rate adjustment, and the first staggered parity bit stream after described staggered system bits, speed are adjusted and the second staggered parity bit stream buffer memory after speed adjustment;

    AndWith speed adjustment unit, the output of described virtual buffer is carried out to the second speed adjustment.
