Abstract
A data processing apparatus (1) includes a signal processing unit (31, 32) and an insertion/deletion unit (33). The signal processing unit performs predetermined signal processing on the wirelessly received data for each frame that includes a predetermined number of samples, and stores the data in the buffers (41, 42). In the case where an amount of the data accumulated in the buffer is out of a predetermined range, the insertion/deletion unit (33) performs insertion/deletion processing that inserts or deletes the data in units of samples.
Claims11
A data processing apparatus comprising:
- a signal processing unit configured to perform predetermined signal processing for each frame having a predetermined number of samples on data received wirelessly and store signal-processed data in a buffer;
- an insertion/deletion unit configured to perform insertion/deletion processing that inserts or deletes the data for each sample in a case where an amount of the data accumulated in the buffer is out of a predetermined range;
- and
- the insertion/deletion unit configured to cause a consecutive predetermined number of the samples to be a target to be inserted or deleted in the frame in a case where a slope of an approximate line calculated on a basis of the consecutive predetermined number of samples is less than a predetermined threshold value.
A data processing method comprising:
- performing predetermined signal processing for each frame having a predetermined number of samples on data received wirelessly and storing signal-processed data in a buffer;
- and
- performing insertion/deletion processing that inserts or deletes the data for each sample in a case where an amount of the data accumulated in the buffer is out of a predetermined range;
- and
- insertion/deletion processing causing a consecutive predetermined number of the samples to be a target to be inserted or deleted in the frame in a case where a slope of an approximate line calculated on a basis of the consecutive predetermined number of samples is less than a predetermined threshold value.
A non-transitory computer readable storage medium having data processing instructions readable by a computer stored thereon, that, when executed by the computer:
- cause the computer to function as:
- a signal processing unit configured to perform predetermined signal processing for each frame having a predetermined number of samples on data received wirelessly and store signal-processed data in a buffer;
- and
- an insertion/deletion unit configured to perform insertion/deletion processing that inserts or deletes the data for each sample in a case where an amount of the data accumulated in the buffer is out of a predetermined range;
- and
- the insertion/deletion unit configured to cause a consecutive predetermined number of the samples to be a target to be inserted or deleted in the frame in a case where a slope of an approximate line calculated on a basis of the consecutive predetermined number of samples is less than a predetermined threshold value.
