Demultiplexing apparatus, multiplexing apparatus, and multi-channel transmission and reception method using the same

摘要

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.

1. A demultiplexing apparatus, comprising:
a processor capable of performing operations comprising:
separating a broadcasting data stream into N input packets;generating (N+1) output packets by connecting first and second pre-headers, each of which comprises a field for multi-channel transmission, with the N input packets; anddistributing the (N+1) output packets over at least two channels,wherein generating the (N+1) output packets comprises generating output packets, placed up to an Nth position in the (N+1) output packets, using the first pre-header, and generating an (N+1)th output packet using the second pre-header.
