Abstract
A transmitter and a receiver of data frames and related methods are disclosed. The transmitter includes: a frame generator configured to generate a first frame comprising data to be transmitted; and a preamble inserter configured to insert a preamble into the first frame, wherein the preamble inserter is further configured to insert, in the preamble, emergency alert service (EAS) information related to a preset emergency alert event, and set an indicator in the frame to indicate whether the EAS information is inserted in the preamble. Accordingly, only important information related to the EAS is transmitted in the form of a preamble to achieve robust transmission, and L1 information of related data is directly transmitted to reduce power consumption.
Claims10
A transmitter comprising:
- a processor configured to generate a frame comprising a preamble and data;
- and
- a transmitter configured to transmit the frame,
- wherein the preamble comprises an indicator to indicate whether an emergency alert service (EAS) information is inserted in the frame,
- wherein the processor is configured to:
- when an emergency alert event does not occur, set the indicator in the preamble to a first value for indicating that the EAS information is not inserted in the frame, and generate the frame comprising the preamble and the data, and
- when the emergency alert event occurs, generate an additional preamble, insert the EAS information in the additional preamble and the data, set the indicator in the preamble to a second value for indicating that the EAS information is inserted in the frame, and generate the frame comprising the preamble, the additional preamble and the data, and
- wherein the EAS information of the additional preamble comprises summary information regarding to the emergency alert event, and the EAS information of the data comprises detailed information regarding to the emergency alert event.
5 more elements
A receiver comprising:
- a reception unit configured to receive a frame from a transmitter;
- and
- a processor configured to determine whether an emergency alert service (EAS) information is in the frame according to an indicator inserted in a preamble included in the frame, and obtain the EAS information from the frame,
- wherein the preamble comprises an indicator to indicate whether the EAS information is inserted in the frame, wherein the transmitter is configured to:
- when an emergency alert event does not occur, set the indicator in the preamble to a first value for indicating that the EAS information is not inserted in the frame, and generate the frame comprising the preamble and data, and
- when the emergency alert event occurs, generate an additional preamble, insert the EAS information to the additional preamble and the data, set the indicator in the preamble to a second value for indicating that the EAS information is inserted in the frame, and generate the frame comprising the preamble, the additional preamble and the data, and
- wherein the EAS information of the additional preamble comprises summary information regarding to the emergency alert event, and the EAS information of the data comprises detailed information regarding to the emergency alert event.
4 more elements
A controlling method of a transmitter, the method comprising:
- generating a frame comprising a preamble and data;
- and
- transmitting the frame,
- wherein the preamble comprises an indicator to indicate whether an emergency alert service (EAS) information is inserted in the frame,
- wherein the generating comprises:
- when an emergency alert event does not occur, setting the indicator in the preamble to a first value for indicating that the EAS information is not inserted in the frame, and generating the frame comprising the preamble and the data, and
- when the emergency alert event occurs, generating an additional preamble, inserting the EAS information in the additional preamble and the data, setting the indicator in the preamble to a second value for indicating that the EAS information is inserted in the frame, and generating the frame comprising the preamble, the additional preamble and the data, and
- wherein the EAS information of the additional preamble comprises summary information regarding to the emergency alert event, and the EAS information of the data comprises detailed information regarding to the emergency alert event.
5 more elements
A controlling method of a receiver, the method comprising:
- receiving a frame from a transmitter;
- and
- determining whether an emergency alert service (EAS) information is in the frame according to an indicator inserted in a preamble included in the frame, and obtain the EAS information from the frame,
- wherein the preamble comprises an indicator to indicate whether the EAS information is inserted in the frame, wherein the transmitter is configured to:
- when an emergency alert event does not occur, set the indicator in the preamble to a first value for indicating that the EAS information is not inserted in the frame, and generate the frame comprising the preamble and data, and
- when the emergency alert event occurs, generate an additional preamble, insert the EAS information in the additional preamble and the data, set the indicator in the preamble to a second value for indicating that the EAS information is inserted in the frame, and generate the frame comprising the preamble, the additional preamble and the data, and
- wherein the EAS information of the additional preamble comprises summary information regarding to the emergency alert event, and the EAS information of the data comprises detailed information regarding to the emergency alert event.
