Método y aparato de separación y de síntesis de señales

摘要

A method and apparatus for splitting an asynchronous signal are provided. The method includes: buffering an asynchronous signal to be split on the basis of a frame and frame sequence, sending n frames of data respectively on n channels in parallel whenever n frames of data have been buffered; and buffering next n frames of data of the asynchronous signal to be split, where n is a ratio of a rate level of the asynchronous signal before split to that of the asynchronous signal after split. A method and apparatus for signal combination are provided. The method includes: buffering n channels of parallel signals to be combined simultaneously on the basis of a frame and according to frame sequence; and sending n channels of frames of data serially after one frame is buffered for each of the n channels of the parallel signals.
