    Abstract: A demultiplexing apparatus, a multiplexing apparatus, and a multi-channel transmission and reception method using the same are provided. The demultiplexing apparatus includes a broadcasting data reception unit for separating a broadcasting data stream into N input packets, an output packet generation unit for generating (N+1) output packets by connecting a pre-header, including a field for multi-channel transmission, with each of the N input packets, and a packet distribution unit for distributing the (N+1) output packets over at least two channels. The multiplexing apparatus includes a packet restoration unit for detecting first field information for restoration and second field information for synchronization from each of pre-headers included in (N+1) output packets received through at least two channels and generating N restoration packets using the first field information and an output synchronization unit for performing output timing synchronization between the N restoration packets using the second field information.
