Abstract
There is provided a frame converter that writes input data included in an input frame to a buffer to accumulate the input data and outputs data read from the buffer as output data included in an output frame, the frame converter includes a setting unit configured to set a time interval from start of resizing of data rate of the input data to start of resizing of data rate of the output data when resizing of an accumulation amount in the buffer is performed in which data rates of the input data and the output data vary, and an adjustment unit configured to adjust to approximate the data rate of the output data to the data rate of the input data after the time interval has elapsed since the start of resizing of data rate of the input data.
Claims9
A frame converter that writes input data included in an input frame to a buffer to accumulate the input data and outputs data read from the buffer as output data included in an output frame, the frame converter comprising:
- a setting unit configured to set a time interval from start of resizing of data rate of the input data to start of resizing of data rate of the output data when resizing of an accumulation amount in the buffer is performed in which data rates of the input data and the output data vary;
- and
- an adjustment unit configured to, after the time interval has elapsed, adjust the data rate of the output data to correspond to the data rate of the input data during the time interval.
A frame conversion method of writing input data included in an input frame to a buffer to accumulate the input data and outputting data read from the buffer as output data included in an output frame, the frame conversion method comprising:
- setting a time interval from start of resizing of data rate of the input data to start of resizing of data rate of the output data when resizing of an accumulation amount in the buffer is performed in which data rates of the input data and the output data vary;
- and
- adjusting, after the time interval has elapsed, the data rate of the output data to correspond to the data rate of the input data during the time interval.
A transmission apparatus having a frame converter that writes input data included in an input frame to a buffer to accumulate the input data and outputs data read from the buffer as output data included in an output frame, the transmission apparatus comprising:
- a setting unit configured to set a time interval from start of resizing of data rate of the input data to start of resizing of data rate of the output data when resizing of an accumulation amount in the buffer is performed in which data rates of the input data and the output data vary;
- and
- an adjustment unit configured to, after the time interval has elapsed, adjust the data rate of the output data to correspond to the data rate of the input data during the time interval.
