摘要:
A digital television transmitting system includes a pre-processor, a packet generator, an RS encoder, and a trellis encoder. The pre-processor pre-processes enhanced data by coding the enhanced data for first forward error correction and expanding the FEC-coded enhanced data. The packet generator generates enhanced data packets including the pre-processed enhanced data and main data packets and multiplexes the enhanced and main data packets. Each enhanced data packet includes an adaptation field in which the pre-processed enhanced data are inserted. The RS encoder performs RS encoding on the multiplexed data packets for second forward error correction, and the trellis encoder performs trellis encoding on the RS-coded data packets.

A vacuum cleaner includes a dust collector that compresses dust stored inside a dust container to minimize the volume of the dust. The dust collector would include one or more pressing plates that are used to compress the dust stored in dust collector. Various methods are used to control movements of the movable pressing plates to facilitate the compression operations. Also, various methods are used to determine when the dust collector is full and needs to be emptied.

Provided is a dust collector of a vacuum cleaner. The dust collector includes a dust separating unit forming a separation space for separating dust from air, a collector body forming a dust storage for storing the dust separated in the dust separating unit, and a dust guide passage connecting the separation space to the dust storage and guiding the separated dust to be discharged from the separation space in a tangential direction.

A digital television transmitting system includes a pre-processor, a packet generator, an RS encoder, and a trellis encoder. The pre-processor pre-processes enhanced data by coding the enhanced data for first forward error correction (FEC) and expanding the FEC-coded enhanced data. The packet generator generates first and second enhanced data packets including the pre-processed enhanced data and main data packets and multiplexes the enhanced and main data packets. The first enhanced data packet includes an adaptation field including the pre-processed enhanced data and second enhanced data packet includes a payload region including the pre-processed enhanced data. The RS encoder performs RS encoding on the multiplexed data packets for second forward error correction (FEC), and the trellis encoder performs trellis encoding on the RS-coded data packets.

A network status display device using a traffic flow-radar is provided. The network status display device includes: a traffic feature extractor calculating flow occupancy rates for total flows, micro-flows and macro-flows with respect to each of a plurality of traffic features with reference to traffic information for each traffic feature such as a network address, a port, a transmitting/receiving host address or a protocol collected by an external traffic information collector, and storing the calculation result; a traffic status display unit displaying the flow occupancy rates for each traffic feature calculated and stored in the traffic feature extractor on a radar with dots for each traffic feature; and a traffic anomaly determination unit determining whether a network status is abnormal with reference to the radar for each traffic feature, detecting and reporting the type of the abnormal network status and harmful or abnormal traffic that generates the abnormal network status, when the abnormal status occurs.
摘要:
A washing method in a steam injection type washing machine in which wash water is heated to generate high temperature and high-pressure steam while passing through the steam supply unit in the wash or rinse cycle, and the generated steam is injected into the wash tub at the top of the wash tub. Accordingly, it is possible to rapidly achieve the wetting of clothes with wash water while achieving an enhancement in sterilization and washing performances. In addition, consumption of water and electrical energy can be reduced.
摘要:
A method for recording data on a recording medium having one or more recording layers. The method includes reading control information including a plurality of control information units for controlling recording/reproducing of data from the recording medium. The control information unit includes a recording speed, an identifier of the recording layer, and a write strategy information depending on the recording speed, where a sequence of the information units is ordered according to the recording speed. The method further provides for recording the data on the recording layer based on the read control information unit including the identifier of the corresponding recording layer on which the data is to be recorded.
