An exhaust duct includes an upper duct being open at opposite ends thereof and a lower duct being open at a tip end thereof. One end of the upper duct is connected, inside an enclosure of a water-heating device, to an exhaust adaptor disposed on the enclosure, and an opposite end of the upper duct communicates with the tip end of the lower duct. The upper duct is connected to the lower duct so as to be slidable along a reference direction in which the lower duct extends from the tip end of the lower duct, and the upper duct is configured to be separated from the exhaust adaptor by sliding along the reference direction.

The present invention relates to a superparticle atomizing device and, more specifically, to a superparticle atomizing device having an inner plate provided at the upper part of an ultrasonic vibrator inside a housing and having a circulation passage formed at the circumference of the inner plate of the inside of the housing by using the rapid flow rate of the air to be ventilated to the inside of the housing through a blower, and thus only liquid microparticles generated at the lower region of the inner plate by the ultrasonic vibrator are pulled up to the upper region thereof, thereby allowing the liquid microparticles to be atomized through an atomizing hole and allowing the liquid microparticles to be rapidly diffused into the air with rapid ventilation air.

Superparticle atomizing device

A broadcast transmitter and a method of processing broadcast data in the broadcast transmitter are disclosed. The method includes the steps of performing RS encoding and CRC encoding on mobile service data to build RS frames belonging to an ensemble, wherein each of the RS frames are mapped into data groups, wherein each of the data groups comprises known data sequences and a portion of FIC data including information for rapid mobile service acquisition, wherein the information for rapid mobile service acquisition includes transport stream identification information for identifying a mobile broadcast carrying a mobile service that includes the mobile service data and C/N indication information for indicating whether the FIC data are applicable to a current transmission frame or a next transmission frame, multiplexing data in the data groups and main service data, and transmitting a transmission frame including the multiplexed data.

Digital broadcasting system and method of processing data in the digital broadcasting system

A digital broadcast receiver and a control method thereof are disclosed. The control method of the digital broadcast receiver includes receiving a broadcast signal into which mobile service data and main service data are multiplexed, extracting TPC signaling information and FIC signaling information from a data group in the received mobile service data, acquiring a program table defining a mapping relation between each of all ensembles transmitted at a physical frequency and at least one virtual channel corresponding to the ensemble, using the extracted FIC signaling information, and detecting IP address information required for channel tuning to the at least one virtual channel corresponding to the ensemble, using the acquired program table.

Digital broadcasting system and method of processing data in digital broadcasting system

The present invention provides a data processing method includes receiving a broadcasting signal where mobile service data are multiplexed with main service data, extracting transmission-parameter-channel signaling information and fast-information-channel signaling information from a data group within the received mobile service data, parsing first program table information describing virtual channel information of an ensemble and a service provided by the ensemble using the fast-information-channel signaling information, the ensemble corresponding to a virtual channel group of the received mobile service data, obtaining permission information of broadcasting contents included in the mobile service data from the first program table information and controlling the contents included in the mobile service data in accordance with the permission information.

A digital broadcasting system and a data processing method are disclosed. A receiving system of the digital broadcasting system includes a baseband processor, a table handler, a FLUTE handler, and a display module. The baseband processor receives a broadcast signal including mobile service data and main service data. Herein, the mobile service data may configure an RS frame. And, the RS frame may include mobile service data, file data, and a table having at least one channel configuration information on the mobile service data and estimated download time for the file data described therein. The table handler parses the table from the RS frame, thereby extracting and outputting at least one channel configuration information on the mobile service data and estimated download time information of the file data. The FLUTE handler parses the file data from the RS frame and storing the parsed data. And, the display module receives the estimated download time for the file data parsed by the FLUTE handler from the table handler, thereby displaying the estimated download time on a portion of a display screen.

A transmitting system, a receiving system, and a method of processing a broadcast signal are disclosed herein. The receiving system include a tuner, a demodulator, a block decoder, an RS frame decoder, and a service manager. The tuner receives a broadcast signal. Herein the broadcast signal includes mobile service data, a service map table signaling access information of the mobile service data, and a plurality of known data sequences. The mobile service data and the service map table are packetized to an RS frame. The demodulator demodulates the received broadcast signal. The block decoder turbo-decodes the mobile service data and the service map table included in the demodulated broadcast signal in block units. The RS frame decoder forming an RS frame including the turbo-decoded mobile service data and service map table, performs primary first cyclic redundancy check (CRC)-decoding and RS-decoding, and performs secondary CRC-decoding on the primarily CRC-decoded and RS-decoded RS frame. The service manager acquires source IP address information of IP datagrams of the RS frame-decoded mobile service data from the service map table.

Transmitting/receiving system and method of processing broadcasting signal in transmitting/receiving system

A method of transmitting a broadcast signal in a transmitter includes transmitting a transmission frame including a plurality of slots during which data groups of mobile data are transmitted, the mobile data being encoded through a Reed-Solomon (RS) frame and each row of a payload of the RS frame including a transport packet of the mobile data.

A receiving system of the digital broadcasting system includes a baseband processor, a first table handler, an audio/video processor, and a content processor. The baseband processor receives a broadcast signal including mobile and main service data. The mobile service data may configure an RS frame, and the RS frame may include mobile service data for mobile audio and/or video broadcasting, a first table describing at least one channel configuration information on the mobile service data, and a second table transmitting content for data casting service. The first table handler parses the first table from the RS frame, thereby acquiring at least one channel configuration information on the mobile service data. The audio/video processor extracts mobile service data of a mobile broadcast program requested for viewing from the RS frame, by referring to the channel configuration information of the first table handler, and decodes the extracted mobile service data, thereby outputting the decoded data to a speaker and/or a display screen. And, the content processor parses the second table from the RS frame to extract content, and processes the extracted content based upon an information associated with the extracted content.
