METHOD AND APPARATUS OF FRAME CONSTRUCTION FOR DOCSIS DATA TRANSMISSION

摘要

PURPOSE: A frame construction method for transmitting DOCSIS(Data Over Cable Service Interface Specification) data and apparatus thereof are provided to minimize the temporal jitter of transmission data and the transmission over head of a downlink PHY(PHYsical) layer. CONSTITUTION: An MAC(Media Access Control) frame division block(201) divides an MAC frame into an MAC management data frame and a user data frame. An input signal processing block(101) previously processes the MAC management data frame and the user data frame. The input signal processing block receives a head-end reference time. A data slice building block(104) creates a data slice based on the user data frame and the MAC management data frame through the input signal processing block.
