Abstract: The present invention relates to a method for receiving urgent alarm contents through a broadcast system. According to an embodiment of the present invention, a method for receiving urgent alarm contents through a broadcast system includes the steps of: receiving a broadcast signal; parsing an urgent alarm table contained in the broadcast signal, the urgent alarm table containing an urgent alarm message and an urgent alarm contents transmission structure descriptor for signaling the information of the urgent alarm contents concerning the urgent alarm message, and the urgent alarm contents transmission structure descriptor containing the IP address of an IP datagram for transmitting the urgent alarm contents; receiving the IP datagram of the IP address; and decoding the IP datagram so as to reproduce the urgent alarm contents.

Abstract: A piston for a compressor includes a bearing portion having a cylindrical shape to define a suction space into which refrigerant is accommodated therein, the bearing portion being provided with a bearing surface facing an inner circumferential surface of the cylinder, a head portion coupled to a front opening of the bearing portion and provided with a plurality of suction ports which communicate with the suction space, the head portion having a compression surface configured to face a compression space to compress the refrigerant in the compression space, and a flange portion coupled to a rear opening of the bearing portion and provided with a through-passage through which the refrigerant is introduced from a muffler unit to the suction space, the flange portion being coupled to a driving portion to transmit driving force to the piston. The bearing surface is subjected to a surface treatment to improve abrasion resistance.

Abstract: A linear compressor includes a cylinder, a piston, and a discharge valve, wherein the piston includes a first part extending in the axial direction, a second part having a diameter greater than that of the first part and formed at one end of the first part facing the discharge valve, and a third part having a diameter greater than that of the first part and formed at the other end of the first part. The second part includes a first outer circumferential surface extending backward from a front surface of the piston, and a second outer circumferential surface spaced apart from the first outer circumferential surface in a direction away from the discharge valve, and a distance between the first outer circumferential surface and an inner circumferential surface of the cylinder is less than a distance between the second outer circumferential surface and the inner circumferential surface of the cylinder.

Abstract: A method and broadcast terminal for receiving an emergency alert message in a sleep mode, are discussed. In one embodiment, the method includes monitoring fast information channel (FIC) wake-up indicator in an FIC segment to determine if the broadcast terminal should be switched to an active mode to receive the emergency alert message; getting an FIC-Chunk payload responsive to the FIC wake-up indicator in the FIC segment, the FIC-Chunk payload including an emergency alert data package indicator; receiving an alert data indicated by a data package identification included in the FIC-Chunk payload, the emergency alert data package indicator indicating an emergency alert table describing the emergency alert message is carried in the data; and parsing the emergency alert message based on the emergency alert table.
