Benefits of technology
The invention is a system and method for transmitting and processing data that can efficiently set channels using signaling information or FIC (a fast information channel). The technical effect of this invention is improved data transmission and processing efficiency.
Problems solved by technology
Therefore, the receiving performance of the receiving system may be deteriorated in a poor channel environment.
Particularly, since resistance to changes in channels and noise is more highly required when using portable and / or mobile broadcast receivers, the receiving performance may be even more deteriorated when transmitting mobile service data by the VSB transmission mode.

A transmitting / receiving system and a data processing method are provided. The receiving system includes a receiving unit, a first processing unit, and a second processing unit. The receiving unit receives a broadcast signal including mobile service data and an FIC segment from at least one slot. A transmission frame includes a plurality of sub-frames for receiving at least one ensemble and at least one mobile service, with a sub-frame comprising a plurality of slots. The first processing unit extracts FIC segments each having a different FIC chunk major protocol version from the broadcast signal and acquires a number of the corresponding FIC segment, a number of the last FIC segment, and FIC chunk major protocol version information from each segment header of the extracted FIC segments. The second processing unit obtains an FIC chunk including signaling information between at least one ensemble and at least one mobile service frame from respective payloads of the FIC segments based upon the acquired number of the corresponding FIC segment, number of the last FIC segment, and FIC chunk major protocol version information.
