Disclosed herein is a multi-compartment type refrigerator and method for controlling the same. The refrigerator includes a plurality of storage compartments. A plurality of evaporators are each positioned in each of the storage compartments, respectively. A compressor supplies refrigerant to the evaporators through a branched refrigerant conduit. A plurality of opening/closing valves are each positioned on a refrigerant conduit upstream of each of the evaporators for selectively controlling supply of refrigerant to the evaporators. Reference compartment defining means defines as a reference storage compartment one of the storage compartments that has a relatively great load. Control means controls starting of the compressor depending on a change of a temperature of the reference storage compartment.

Multi-compartment type refrigerator and method for controlling the same

A digital video playback apparatus which selectively reproduces video signals that are recorded by using a plurality of cameras each at different angles and method therefor. The digital video playback apparatus reads out first and second video stream data and first and second audio stream data, which are compressed and recorded on a recording medium. A demultiplexer separates a signal output of the digital playback apparatus into system information, the first and second video stream data, and the first and second audio stream data. First and second video decoders expand the first and second compressed video stream data outputs, respectively. First and second audio decoders decode the first and second audio stream data outputs from the demultiplexer and expand the first and second audio stream data decoded into original 4-channel audio signals, respectively. A key input section generates first and second angle selection signals. A controller analyzes the system information, and generates a switching control signal. First and second switches selects the first and second video and audio stream data according to the switching control signal.

Digital video playback apparatus and method

A method for controlling a refrigerator constructed with a main body formed with a storage compartment accommodating therein food, a door opening and closing the storage compartment, a temperature sensor provided within the main body, by detecting a temperature of the main body, cooling is provided to the main body to cool the storage compartment in steps of establishing a control temperature of the temperature sensor to correspond to the temperature of the storage compartment; and continuously operating the cooling means until the temperature detected by the temperature sensor reaches the control temperature at an initial operation state. With this configuration, because the compressor is continuously operated until the temperature detected by the temperature sensor reaches the control temperature, the rate of cooling the stored food is enhanced and at the same time a desired storage temperature is achieved. In addition, the overload of the compressor may be prevented by limiting the continuous operation time of the compressor.

Method for controlling refrigerator

A digital video playback apparatus selectively reproduces video signals which are recorded by using a plurality of cameras each at different angles and method therefor. A digital playback apparatus reads out first and second video steam data and first and second audio stream data, which are compressed and recorded on a recording medium. A demultiplexer separates a signal output of the digital playback apparatus into system information, the first and second video stream data, and the audio stream data. First and second video decoders expand the first and second compressed video stream data outputs. An audio decoder decodes and expands the audio stream data outputs from the demultiplexer. A key input section generates first and second angle selection signals. A controller analyzes the system information, and generates a switching control signal and a plurality of delay time and gain control signals. A switch selects the first and second video stream data according to the switching control signal. A delay time and gain control circuit delays the audio stream data outputs from the audio decoder according to the delay time control signals, and controls gains of the delayed audio stream data according to the gain control signals.

Multi-angle digital and audio synchronization recording and playback apparatus and method

The present invention is disclosed to provide a power saving apparatus and a method for reducing an electric power of the automatic vending machine when goods stored or provided at an inner part of the automatic vending machine is maintained at a goods sold out state or when an error occurs due to some trouble at a predetermined load(s) of the inner part of the automatic vending machine. In the automatic vending machine, with an operating time of a heater and a compressor being reduced power consumption to be used at the sales stop state of the automatic vending machine can be reduced according to reduced operating time of the inner load at a predetermined ratio.

Power saving apparatus of an automatic vending machine and method thereof

A time displaying apparatus and method for an automatic vending machine is able to display current time and operation state so that user can conveniently use the vending machine. A time displaying apparatus for an automatic vending machine has a timer for counting a current time. A control part generate a control signals to display a current time counted by the timer when coins are not inserted in the mechanism after having checked the state of coins inserted, to display the amount of coins detected by the coin detecting mechanism when the coins are inserted. A display part displays selectively the current time or the amount of coins according to the control signal of the control part.

Time displaying apparatus and method for automatic vending machine

A goods selecting apparatus and method for an automatic vending machine enables uses a control device to take necessary actions in case a user selects an article in error among goods stored in the automatic vending machine thereby preventing undesired goods from being extracted. The apparatus has a key input part for generating a key signal corresponding to a cancel or an extract selection of a goods selected by an user. A control part is provided and selectively generates a control signal to cancel or to send the selected goods to a goods extracting slot according to a key signal from the key input part within a predetermined time.
