Broadcasting system and method of processing data in a broadcasting system

The broadcasting system and method for processing data in the broadcasting system is proposed. Transmission system thus multiplexed in the manner common in accordance with the MPEG encoded data and the channel sequence number of the packet added the additional data embedded coded data. Then, the multiplexed data is transmitted to the receiving system with the multiplexing information. On the other hand, the receiving system from the multiplexed data, and detects the multiplexed information, and generates a sequence of null, the null then demultiplexes the MPEG data and the additional data from the multiplexed data with the multiplexing sequence and information. Multiplexed, transmission system, receiving system, multiplexing information
