Abstract:
An electronic apparatus which is capable of being worn on a user's body is provided. The electronic apparatus includes first and second wearing units configured to connect to each other, the first wearing device including a first measurer configured to measure the user's body, and a first communicator configured to communicate with the second wearing device, and the second wearing device including a second measurer configured to measure a user's body, and a second communicator configured to communicate with the first wearing device, and a at least one main processor configured to process a first measurement signal generated by using the first measurer while the first and second wearing devices are connected to each other, and to process a second measurement signal measured and generated by the second measurer while the first and second wearing devices are either connected to each other or disconnected from each other.
Abstract:
A noise filling method is provided that includes detecting a frequency band including a part encoded to 0 from a spectrum obtained by decoding a bitstream; generating a noise component for the detected frequency band; and adjusting energy of the frequency band in which the noise component is generated and filled by using energy of the noise component and energy of the frequency band including the part encoded to 0.
Abstract:
A method of providing notification information includes: obtaining information regarding a sensing region; determining a visible region and a non-visible region within the sensing region; and providing notification information regarding the non-visible region.
Abstract:
A bit allocating method is provided that includes determining the allocated number of bits in decimal point units based on each frequency band so that a Signal-to-Noise Ratio (SNR) of a spectrum existing in a predetermined frequency band is maximized within a range of the allowable number of bits for a given frame; and adjusting the allocated number of bits based on each frequency band.
Abstract:
Provided are a method and apparatus for encoding or decoding an audio signal or a speech signal. In the encoding method, encoding is performed by performing domain transformation on a received signal in units of frequency bands by applying a psychoacoustic model, encoding the transformation result with respect to predetermined one or more frequency bands by using a high temporal resolution coding tool, and then quantizing the encoding result. In the decoding method, decoding is performed by inversely quantizing signals obtained by encoding in units of frequency bands, decoding one or more signals from among the inversely quantized signals, which are allocated to one or more frequency bands which have a predetermined domain resolution, determined by applying the psychoacoustic model, that is greater than a predetermined value, according to a predetermined method, and then inversely transforming either the inversely quantized or the one or more decoded signals.
Abstract:
Provided is a method of processing content based on bio-signals, the method includes: acquiring bio-signals of a user; determining a parameter for altering the characteristics of content or determining a type of content to be output, based on the acquired bio-signals; processing the content or determining the type of content to be output, based on the determined parameter; and outputting the processed content or the determined type of content.
Abstract:
A display apparatus is provided. The display apparatus includes a display panel configured to display a content, a view field divider provided at a front side of the display panel and configured to divide a view field in which the content is provided, a sensor configured to sense a user, and a processor configured to identify an area which is viewable by the sensed user between a first area which is viewable by a user at a first direction and a second area which is viewable by a user at a second direction based on the display apparatus, and control the view field divider to provide the content to the identified area.
Abstract:
A sound outputting apparatus which includes a communicator to communicate with an electronic apparatus and receive first audio data, an output module to output the first audio data received, and to output second audio data, which is modified data of the first audio data, a sensor to detect brainwave data of a user, and a processor to control so that the brainwave data of the user detected through the sensor is transmitted to the electronic apparatus through the communicator, and so that the second audio data is received from the electronic apparatus.
Abstract:
A host apparatus, a user terminal apparatus, a method of controlling a charger, and a method of communication thereof. The host apparatus includes: a connector which includes a terminal to which the user terminal apparatus is connected; a power supplier which supplies power to the connector; a controller which, if the host apparatus operates in a first operation mode when the user terminal apparatus is connected to the connector through the terminal, charges a battery of the user terminal apparatus with the power supplied from the power supplier; and a charging maintainer which, if the host apparatus operates in a second operation mode, charges the battery with power supplied from the power supplier.
