Embodiment Construction
[0051] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:
[0052] Before that, first introduce the error correction structure under the strict delay limit, the specific function realization of this structure will depend on the setting of its parameters. In order to facilitate description of all processing flows of the present invention, the symbols of several groups of parameters used in the error correction structure are defined below:
[0053] Table 1: Parameter definitions of the error correction structure
[0054]
[0055]
[0056] 1. Determination of n value: definition D E2E is the maximum possible end-to-end delay, define d max The maximum delay required to send a packet; obviously, the determination of the value of n is only related to the maximum delay D E2E and d max relevant, so once D E2E and d max Determined, the value of n is a fixed value, and n=K at the same time i +p i , then...
