Broadcasting system and method |
摘要 |
Disclosed is a broadcasting system and method for transmitting/receiving a broadcast data in a broadcasting system, which reduces an application download period by efficiently utilizing a data broadcasting stream and a return channel for application download when a reception terminal receives a data broadcast. The broadcasting system and method includes a data broadcast reception terminal to receive the broadcast data and a bi-directional broadcasting server to communicate with the data broadcast reception terminal through a return channel: the data broadcast reception terminal receives a data broadcast stream during one broadcast transmission period, and requests the bi-directional broadcasting server to transmit a portion of the data broadcast stream (e.g. section data) through the return channel when the section data of the received data broadcast stream is lost; the bi-directional broadcasting server transmits the section data to the data broadcast reception terminal when a download request is received for the section data from the data broadcast reception terminal; and the data broadcast reception terminal performs modularization using a received lost section data and the previously-received section data to extract application files when receiving the lost section data and displays the extracted application files on a screen.
