  • Patent number: 11996107
    Abstract: Provided is a technique according to which it is possible to obtain a decoded sound signal of high sound quality without significantly increasing the delay time compared to a configuration in which only a decoded sound signal of the minimum necessary sound quality is obtained. In a terminal apparatus connected to a first communication line and a second communication line with a lower priority level therethan, sound signals of multiple channels are obtained and output based on a monaural code included in a first code string input from the first communication line and an extended code included in a second code string with the closest frame number to that of the monaural code among extended codes included in the second code string input from the second communication line.

  • Patent number: 11972768
    Abstract: An autocorrelation calculation unit 21 calculates an autocorrelation RO(i) from an input signal. A prediction coefficient calculation unit 23 performs linear prediction analysis by using a modified autocorrelation R?O(i) obtained by multiplying a coefficient wO(i) by the autocorrelation RO(i). It is assumed here, for each order i of some orders i at least, that the coefficient wO(i) corresponding to the order i is in a monotonically increasing relationship with an increase in a value that is negatively correlated with a fundamental frequency of the input signal of the current frame or a past frame.

  • Patent number: 11973900
    Abstract: A technique is provided that can reduce degradation of the sound quality due to a tandem connection of paired coding and decoding, and can reduce the operation processing amount and the required memory amount of a multipoint control unit. In multipoint connection between terminals of a plurality of communication networks (for example, a fixed phone line and a mobile phone line) having different communication capacities, when a multichannel coding including a monaural coding scheme of a communication network having a smaller communication capacity is used in a communication network having a larger communication capacity to transmit sounds of a plurality points to the communication network terminal having the larger communication capacity, control is exercised such that monaural codes of the plurality points are output.

  • Publication number: 20240119947
    Abstract: There is provided a technology that improves, in a case where there is a sound signal obtained from a different code that is different from a code from which a decoded sound signal is obtained and that is derived from the same sound signal, the decoded sound signal by using the sound signal obtained from the different code. A signal (hereinafter, referred to as a decoded sound common signal) obtained by downmixing a decoded sound signal of each channel is subjected to signal purification using a monaural decoded sound signal to thereby generate a purified common signal, and in each channel, a signal obtained by upmixing the decoded sound common signal is subtracted from the decoded sound signal and a signal obtained by upmixing the purified common signal is added thereto, to thereby generate a purified decoded sound signal.

  • Patent number: 11055338
    Abstract: Embodiments of the present invention include generating a facet tree based on words found in one or more documents, the facet tree being a tree data structure that defines hierarchical relationships between a plurality of words. The method may further include calculating a degree of similarity between a first word and a second word based on similarity of usage of the first word and the second word in the one or more documents, and generate a facet tree based on the degree of similarity. The method may further include, for each of one or more candidate words in the one or more documents, calculating a degree of correlation between a co-occurrence of two or more existing facet tree entries in a document and an occurrence of the candidate word in the document, and updating the facet tree on the basis of the one or more degrees of correlation.

  • Patent number: 10956470
    Abstract: Facet-based query refinement based on multiple query interpretations is provider through a process that includes receiving a query for querying documents, of a whole document set, that deviate by one or more facet values. The process generates different query interpretations from query text of the query. The process executes the different query interpretations to obtain resulting document sets. For each different query interpretation, the executing executes the query interpretation to obtain a resulting document set corresponding to that query interpretation, and identifies facet values represented in the resulting document set. The process builds and presents to a user a query refinement interface, presenting the different query interpretations and properties of the resulting document sets, as well as, for each of the one or more facet values, and relative to each other, facet value representation of the facet value in each of the resulting document sets.

  • Publication number: 20140306998
    Abstract: A computer is disclosed that performs a land boundary display process. The computer executes an imaging process when an imaging request is detected. The computer specifies an imaging range based on a location, an imaging orientation and an elevation angle of a terminal apparatus when the imaging process is executed. Also, the computer specifies an area corresponding to a plot of land in a captured imaged based on the imaging range being specified. After that, the computer reads out boundary line information of the plot of land corresponding to latitude and longitude information from a storage part, and generates an image by overlapping an area corresponding to the plot of land being specified with the boundary line information being read out. Then, the computer displays the image at a display device.
