Broadcast receiver and method of processing data
First Claim
Patent Images
1. A broadcast receiver, comprising:
- a signal receiving unit for repeating, when an operating mode of the broadcast receiver has been switched to a Discontinuous Receive (DRx) mode, preset wake-up and sleep sections, and receiving a broadcast signal containing main broadcast service and mobile broadcast service data in the wake-up section;
a known sequence detector for detecting known data included in the received broadcast signal; and
a channel equalizer for using the detected known data, thereby channel-equalizing the received mobile broadcast service data,wherein the mobile broadcast service data configures a data group, wherein the data group is divided into a plurality of regions, wherein N number of known data sequences are inserted in some regions among the plurality of regions within the data group, and wherein initialization data are inserted at a beginning portion of each known data sequence, the initialization data being used for initializing a memory included in a trellis encoder of a broadcast transmitting system.

Abstract
A broadcast receiver and a method of processing data are disclosed. The broadcast receiver includes a signal receiving unit, a known sequence detector, and a channel equalizer. The signal receiving unit repeats, when an operating mode of the broadcast receiver has been switched to a Discontinuous Receive (DRx) mode, preset wake-up and sleep sections, and receives a broadcast signal containing main broadcast service and mobile broadcast service data in the wake-up section. The known sequence detector detects known data included in the received broadcast signal. The channel equalizer uses the detected known data, thereby channel-equalizing the received mobile broadcast service data.

9. A method for processing data in a broadcast receiver, comprising:
-
repeating, when an operating mode of the broadcast receiver has been switched to a Discontinuous Receive (DRx) mode, preset wake-up and sleep sections, and receiving a broadcast signal containing main broadcast service and mobile broadcast service data in the wake-up section; detecting known data included in the received broadcast signal; and channel-equalizing the received mobile broadcast service data using the detected known data, wherein the mobile broadcast service data configures a data group, wherein the data group is divided into a plurality of regions, wherein N number of known data sequences are inserted in some regions among the plurality of regions within the data group, and wherein initialization data are inserted at a beginning portion of each known data sequence, the initialization data being used for initializing a memory included in a trellis encoder of a broadcast transmitting system. - View Dependent Claims (10, 11, 12, 13, 14, 15)
