Abstract

Technology for transmitting and receiving a biosignal based on a pattern related to the biosignal and a feature point included in the biosignal. A biosignal transmitter includes a biosignal obtaining unit configured to obtain a biosignal comprising a plurality of unit signals, a parsing unit configured to parse the biosignal to extract a first unit signal of the plurality of unit signals, a pattern obtaining unit configured to obtain a pattern related to the biosignal based on the first unit signal, and a transmitting unit configured to transmit information related to a feature point of the first unit signal based on the first unit signal and the pattern.

Claims

1. A biosignal receiver comprising:

one or more processors configured to;

determine a type of a received reception signal related to a biosignal comprising a plurality of unit signals;

obtain a pattern related to the biosignal from a storage space provided in advance in response to the type of the reception signal being determined to be a first type of reception signal; and

reconstruct a first unit signal of the plurality of unit signals based on the pattern and information related to a feature point of the first unit signal;

store the pattern related to the biosignal in the storage space in response to the type of the reception signal being determined to be a second type of reception signal; and

obtain a second unit signal of the plurality of unit signals in response to the type of the reception signal being determined to be a third type of reception signal,

wherein the reception signal determined to be the first type of reception signal comprises the information related to the feature point of the first unit signal,

wherein the reception signal determined to be the second type of reception signal comprises the pattern related to the biosignal, and

wherein the reception signal determined to be the third type of reception signal comprises the second unit signal.

2. The biosignal receiver of claim 1, wherein the one or more processors are further configured to reconstruct the biosignal based on the first unit signal and the second unit signal.

3. A processor-implemented method of transmitting a biosignal, the method comprising:

extracting a signal from the biosignal;

obtaining a biosignal pattern based on the signal, wherein the obtaining of the biosignal pattern further comprises;

obtaining the biosignal pattern in response to a determination that a correspondable pattern has previously been generated, and

obtaining signals from the biosignal and generating a pattern that correlates to the signal based on the obtained signals, in response to a determination that the correspondable pattern has not previously been generated;

transmitting the generated pattern in response to the pattern being newly generated;

determining a similarity between the signal and the biosignal pattern when the biosignal pattern is obtained, in the obtaining, without the generating of the pattern;

obtaining information related to at least one feature point of the signal based on the signal and the biosignal pattern and transmitting the information related to the at least one feature point of the signal, in response to the similarity being greater than a predetermined threshold; and

transmitting the signal, in response to the similarity being less than the predetermined threshold.

4. The method of claim 3, wherein the transmitting of the information related to the signal requires transmitting a smaller amount of data than the transmitting of the signal.

5. The method of claim 3, wherein the obtaining of the biosignal pattern comprises:

determining whether the signal corresponds to a predetermined biosignal pattern;

obtaining the predetermined biosignal pattern as the obtained biosignal pattern in response to a result of the determining being that the signal corresponds to the predetermined biosignal pattern; and

generating a new biosignal pattern as the obtained biosignal pattern in response to a result of the determining being that the signal does not correspond to the predetermined biosignal pattern; and

the method further comprises transmitting the new biosignal pattern.

6. A non-transitory computer-readable storage medium storing a program for controlling a computer to perform the method of claim 3.

7. A processor-implemented method of receiving a biosignal, the method comprising:

receiving a reception signal related to the biosignal comprising a plurality of unit signals;

determining a type of the reception signal;

obtaining a pattern related to the biosignal from a storage space provided in advance in response to the determining of the type of the reception signal determining that the reception signal is a first type of reception signal;

reconstructing a first unit signal of the plurality of unit signals based on the pattern and information related to a feature point of the first unit signal;

storing the pattern related to the biosignal in the storage space in response to the determining of the type of the reception signal determining that the reception signal is a second type of reception signal; and

obtaining a second unit signal of the plurality of unit signals in response to the determining of the type of the reception signal determining that the reception signal is a third type of reception signal,

wherein the reception signal determined to be the first type of reception signal comprises the information related to the feature point of the first unit signal,

wherein the reception signal determined to be the second type of reception signal comprises the pattern related to the biosignal, and

wherein the reception signal determined to be the third type of reception signal comprises the second unit signal.

8. A non-transitory computer-readable storage medium storing a program for controlling a computer to perform the method of claim 7.

9. A processor-implemented method of transmitting a biosignal, the method comprising:

obtaining the biosignal comprising a plurality of unit signals;

parsing the biosignal to extract a first unit signal of the plurality of unit signals;

generating a pattern that correlates to the first unit signal in response to a determining of which pattern, of a plurality of patterns, correlates to the first unit signal indicating that a correspondable pattern has not yet been generated;

transmitting the generated pattern that correlates to the first unit signal when the determining of which pattern correlates to the first unit signal indicates that the correspondable pattern has not yet been generated;

transmitting information related to a feature point of the first unit signal when the first unit signal correlates to a predetermined pattern; and

transmitting the first unit signal when the first unit signal does not correlate to the predetermined pattern.
