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.

A terrestrial digital television receiver includes a tuner, a microcomputer, and a demodulator. The microcomputer initially determines whether the DTV receiver is on, a power-on or power-off mode. If the DTV receiver is on the power-off mode, the microcomputer, control operation of the tuner to tune to a predefined emergency alert channel to receive a master guide table. The demodulator parses the master guide table. If the parsed master guide table indicates that a new emergency alert message is being received, the microcomputer automatically sets the DTV receiver on the power-on mode and controls operation of the tuner to tune to the emergency alert channel.

A terrestrial digital television receiver includes a tuner, a demodulator, a demultiplexer, a decoder, and a controller. The tuner receives a terrestrial television signal having an emergency alert table which contains text representing an emergency alert message. The demodulator demodulates the television signal and the demultiplexer demultiplexes the emergency alert table from the demodulated signal. The decoder parses the text data representing the emergency alert message, and the controller control operation of a display device such that the emergency alert message is scrolled across a predetermined portion of a video screen.

An emergency alert message is included in a cable broadcast signal. The emergency alert message includes major and minor details channel numbers associated with a details channel. A details channel number is configured based on the major details channel number when the minor details channel number is set to a null value. Next, it is tuned to a channel frequency of a digital cable channel corresponding to the details channel number when the details channel number exists in a digital channel number list. Alternatively, the emergency alert message includes a details channel source field which indicates whether a details channel is a digital or an analog channel. Then, it is tuned to a channel frequency of one of a digital cable channel and an analog cable channel based upon a value of the details channel source field.

An apparatus and method for processing channel information in a broadcasting system for transmitting/receiving a cable broadcasting signal are disclosed. In particular, each receiver transmits host channel view capacity information containing the length of channel information which can be displayed on a screen to a headend located at a remote place, and the headend stores the host channel view capacity information in a database and determines and transmits most suitable channel information of each receiver to each receiver. Accordingly, each receiver can display only channel information, which can be most accurately recognized by viewers, among a variety of the channel information which can be displayed on the screen.
