    摘要: An electronic device includes a display screen and circuitry. The circuitry receives a first frequency modulated (FM) signal from a first FM radio transmitter, via a first FM radio channel. The first FM signal comprises a broadcast data signal that includes an audio segment of aural information of a performer-of-interest at of a live event, text information associated with the audio segment, and synchronization information. The synchronization information is associated with the text information and the audio segment. The circuitry extracts the synchronization information from a plurality of data packets of the broadcast data signal. The circuitry extracts a portion of the text information from the extracted plurality of data packets of the broadcast data signal based on the extracted synchronization information. The circuitry controls display of the extracted portion of the text information on the display screen.

    摘要: A method for processing audio signals in a radio transmitter, includes: receiving an analog audio sample stream and a digital audio sample stream; determining offsets in time between the analog audio stream and the digital audio stream using a normalized cross-correlation of audio envelopes of the analog audio sample stream and the digital audio sample stream; filtering the determined offsets in time to produce filtered offset values; determining an alignment slip adjustment value as a function of the filtered offset values; aligning the analog audio sample stream and the digital audio sample stream using the determined alignment slip adjustment value; and generating a hybrid radio signal for broadcast that includes time-aligned analog audio and digital audio.

    摘要: A digital broadcast system including a broadcast receiving system and data processing method are disclosed. In the broadcast receiving system receiving broadcast signals, the broadcast receiving system includes a transmission parameter decoding unit, a known sequence detector, and a burst controller. The transmission parameter decoding unit detects information on a burst of a received signal from broadcast data having main service data and mobile service data multiplexed therein within a field of the received signal and outputs the detected information on the burst. The known sequence detector receives burst information from the transmission parameter decoding unit and uses the received burst information and known data position information included in the received data, so as to output burst control information. The burst controller uses the burst control information to control power supply of the broadcast receiving system.
