- Abstract
- Disclosed herein is a non real-time broadcast receiving system. The system includes: a non real-time service decoder dividing received non real-time service content into a transmission block according to a protocol; a service content manager monitoring whether the receive of the non real-time service content stops and acknowledging a schedule regarding whether a portion with errors in the non real-time service content is retransmitted; a memory storing a portion without errors in the non real-time service content; a file checker checking whether errors are produced during the receive of the non real-time service contents and determining whether the portion with errors in the non real-time service content is retransmitted; a retransmission request signal generator generating a retransmission request signal; a return channel transmitter transmitting the retransmission request signal; and a return channel receiver receiving data corresponding the portion with error.
