Disclosed are a slave node device in a multimedia transmission system and the multimedia transmission system. The slave node device comprises: a receiving module configured to receive a data frame from an upstream node; a sending module configured to send the data frame to a downstream node; an analyzing module configured to analyze the received data frame and store the analyzed data into a bus data buffer area; an encoding module configured to read data from the bus data buffer area or a local data buffer area according to a data selection control signal and output the encoded data; a control signal generation unit configured to generate the data selection control signal according to a preset strategy and a data transmission state; and a data path switching module configured to take the output of the receiving module or the encoding module as the input of the sending module according to the data selection control signal. The slave node device selects the best data path for the entire data frame or each part of the data frame decomposed from the data frame and transmits the data frame by using the best data path, thereby reducing the node delay of the slave node device.
