Electronic device and method for updating channel map thereof

A background music providing method includes storing an audio parameter with respect to background music reproduced while a background music identification mode is being activated, acquiring information on the background music based on the audio parameter when receiving a background music identification command, and transmitting the information on the background music to an external apparatus.

A display apparatus includes an input interface that receives a user input for selecting a channel, a tuner that receives a broadcast signal corresponding to the channel, a display that displays a content included in the broadcast signal, a storage configured to store channel information obtained from the broadcast signal, a communicator configured to communicate with an external apparatus, and a controller that selects a channel based on the user input, displays content corresponding to the changed channel on the display, acquires a channel number, a source ID and a channel name with respect to the channel, and transmits the channel number, the source ID and the channel name to a server.

Display apparatus and method for acquiring channel information of a display apparatus

A voice recognition device includes an extractor configured to extract at least one of a first utterance element indicating an execution command and a second utterance element indicating a subject, from a user's voice utterance, a domain determiner configured to determine a current domain to provide response information regarding the voice utterance based on the first and the second utterance elements, and a controller configured to determine a candidate conversation frame to provide the response information regarding the voice utterance on at least one of the current domain and a previous domain based on a conversation state of the current domain, wherein the previous domain is determined from a previous voice utterance of the user.

Voice recognition device and method of controlling same

A voice recognition apparatus and a method for providing response information are provided. The voice recognition apparatus according to the present disclosure includes an extractor configured to extract a first utterance element representing a user action and a second utterance element representing an object from a user's utterance voice signal; a domain determiner configured to detect an expansion domain related to the extracted first and second utterance elements based on a hierarchical domain model, and determine at least one candidate domain related to the detected expansion domain as a final domain; a communicator which performs communication with an external apparatus; and a controller configured to control the communicator to transmit information regarding the first and second utterance elements and information regarding the determined final domain.

Voice recognition apparatus and method for providing response information

Provided are an apparatus and method for displaying a document, the document display apparatus including an image processor which displays a document including a plurality of pages; a memory unit which stores individual unit elements constituting the document and image data including the individual unit elements; and a controller which controls the image processor to generate the image data corresponding to at least one page estimated to be turned to among the plurality of pages, store the image data in the memory unit, and display the image data corresponding to a requested page among the stored image data when a user requests a page transition.

Apparatus and method for displaying document

A motion estimator for generating an interpolation frame based on current and previous frames is provided. The motion estimator includes: a first candidate motion vector calculating unit which divides the current frame into plural blocks and generates plural first candidate motion vector groups, each group including a first candidate motion vector for each of the blocks calculated based on a previous motion vector previously estimated; a second candidate motion vector calculating unit which calculates plural second candidate motion vectors for each of the blocks, each of the second candidate motion vectors being calculated based on a respective first candidate motion vector included in each of the first candidate motion vector group; and a final motion vector deciding unit which selects a final motion vector for each of the blocks from among the second candidate motion vectors, the interpolation frame being generated based on the final motion vector.

Motion estimator and motion estimating method

A sense amplifier circuit for a nonvolatile semiconductor memory device, with NAND structured cells, includes a bit line isolation section located between a pair of bit lines connected to a memory cell array and a pair of sub-bit lines connected to an input/output gate circuit, a latch type voltage-controlled current source having n-channel MOS transistors connected to the sub-bit lines, and a switching section connected between the voltage-controlled current source and a signal line. The bit lines are electrically isolated from the sub-bit lines by provision of a bit line isolation section receiving an isolation control signal during the sensing operation. The sense amplifier circuit sensing operation is not affected by bit line load impedance and, accordingly, the sensing speed is improved and peak current is reduced.

Sense amplifier circuit of a nonvolatile semiconductor memory device

An input protection circuit for a semiconductor memory device senses when the level of an external input signal drops below a reference voltage corresponding to a predetermined logic level, thereby enabling instant correction. The input protection circuit is interposed between an external power voltage terminal and an input terminal of the input buffer, and the external power voltage is transferred to the input terminal of the input buffer when the level of the external input signal applied to the input terminal drops below the predetermined logic level. The circuit includes an internal reference voltage generator which supplies a voltage having a level corresponding to the predetermined logic level and designed to compensate for a known device offset so that the external input signal applied to the input terminal can be instantly corrected.
