Abstract: A broadcast receiving system capable of receiving mobile broadcast data and a method for processing broadcast signals are disclosed. The broadcast receiving system includes N number of antenna elements, a demodulator, a transmission parameter detector, and a block decoder. The N number of antenna elements receives each of the broadcast signals. The demodulator demodulates the broadcast signal having greater signal strength among each of the received broadcast signals. The transmission parameter detector detects the transmission parameter. The block decoder symbol-decodes the mobile broadcast service data included in the received broadcast signal in block units, based upon the detected transmission parameter.

Abstract: A broadcast receiving system capable of receiving mobile broadcast data and a method for processing broadcast signals are disclosed. The broadcast receiving system includes a first receiving unit, a second receiving unit, a known sequence detector, a equalizer, and a display unit. The first receiving unit receives a first broadcast signal including first mobile broadcast service data and first main broadcast service data. The second receiving unit receives a second broadcast signal including second mobile broadcast service data and second main broadcast service data. The known sequence detector detects at least one of known data included in the received first broadcast signal and known data included in the received second broadcast signal. The channel equalizer uses the detected known data, thereby channel-equalizing the received first and second mobile broadcast service data corresponding to the detected known data. The display unit provides any one of first video data and second video data included in the channel-equalized first and second mobile broadcast service data to a user.
Abstract translation: 公开了能够接收移动广播数据的广播接收系统和处理广播信号的方法。 广播接收系统包括第一接收单元，第二接收单元，已知序列检测器，均衡器和显示单元。 第一接收单元接收包括第一移动广播业务数据和第一主广播业务数据的第一广播信号。 第二接收单元接收包括第二移动广播业务数据和第二主广播业务数据的第二广播信号。 已知的序列检测器检测包括在接收到的第一广播信号中的已知数据中的至少一个和包括在所接收的第二广播信号中的已知数据。 信道均衡器使用检测到的已知数据，从而对接收到的与检测到的已知数据相对应的第一和第二移动广播服务数据进行信道均衡。 显示单元将包括在信道均衡的第一和第二移动广播服务数据中的第一视频数据和第二视频数据中的任何一个提供给用户。

Abstract: A method and apparatus for transmitting a broadcast signal are provided. Data of data packets is encoded to add first parity data to the data packets. The data packets include broadcast data and signaling data for a service. The signaling data includes type information indicating a type of the service and channel information of the service. Information for acquisition of the signaling data is predefined. The encoded data is block interleaved. The block-interleaved data is convolutional interleaved. Transmission parameters are first encoded for signaling the broadcast data to add second parity data to the transmission parameters, and the first-encoded transmission parameters are second encoded at a code rate. A frame including the convolutional interleaved data and the second-encoded transmission parameters is built. The broadcast signal including the frame is transmitted. The transmission parameters include information for identifying a number of the first parity data.
