Problems solved by technology

Therefore, in a poor channel environment, the reception performance of the receiving system will deteriorate
Specifically, due to the greater need to resist channel variations and noise when using portable and / or mobile broadcast receivers, reception performance may be worse when mobile service data is transmitted via VSB transmission mode

Embodiment approach

[0185] According to an embodiment of the present invention, the present invention uses the FIC_type field in the header of the empty FIC section as identification information for identifying the empty FIC section. In this embodiment, the value of the FIC_type field in the empty FIC segment header is set to "11" to identify the corresponding empty FIC segment. More specifically, when the value of the FIC_type field in the empty FIC segment header is set to "11" and is transmitted to the receiving system, the receiving system may discard the payload of the FIC segment whose FIC_type field value is set to "11", while The corresponding FIC segment payload need not be processed. Here, the value "11" is only an exemplary value given to facilitate and simplify understanding of the present invention. Any value capable of identifying an empty FIC segment can be specified for the FIC_type field as long as pre-configuration between the receiving system and the transmitting system is est...

Abstract

A transmitting / receiving system and a data processing method of the same are disclosed herein. The receiving system may include a receiving unit, a first processing unit, and a second processing unit. The receiving unit receives a broadcast signal including mobile service data from at least one slot. The first processing unit acquires FIC segments divided from an FIC chunk of at least one sub-frame. Herein, each FIC segment comprises a 2-byte segment header and a 35-byte segment payload. The segment header includes an FIC type information, a number of a corresponding FIC segment, and a number of a last FIC segment among the FIC segments divided from the FIC chunk. The second processing unit obtains the FIC chunk including signaling information between at least one ensemble and at least one mobile service from respective payloads of the FIC segments, based upon the acquired FIC type information, number of the corresponding FIC segment, and number of the last FIC segment of each FIC segment.

Description

technical field [0001] The present invention relates to a transmission system for transmitting digital broadcast signals, a reception system (or receiver) for receiving digital broadcast signals transmitted from the transmission system, and data processing in the transmission system and the reception system (or receiver) Methods. Background technique [0002] The vestigial sideband transmission mode adopted as a digital broadcasting standard in North America and Korea is a system using a single carrier method. Therefore, in a poor channel environment, the receiving performance of the receiving system will deteriorate. In particular, reception performance may be further deteriorated when mobile service data is transmitted through the VSB transmission mode due to the greater need to resist channel variations and noise when using a portable and / or mobile broadcast receiver. Contents of the invention [0003] Accordingly, the present invention is an effort to provide a trans...
