バッファ管理システム、ディジタルオーディオ受信機、ヘッドホン、スピーカ、バッファ管理方法
Document Type and Number:
Japanese Patent JP2007501428
Kind Code:
A
Abstract:
The buffer management system ( 100 ) is arranged to control in a data communication system an end to end delay (Delta) of a data unit ( 150 ) from input to output. Blocks ( 104, 106 ) of data units ( 150, 152 ) are written in a buffer ( 102 ) with a block write rate (Rw), and data units ( 154, 156 ) are read from this buffer ( 102 ) with a read rate (Rr). The end to end delay (Delta) is controlled by adapting the read rate (Rr) from the buffer ( 102 ), and hence the buffer filling (F) on the basis of measurements of delays in the buffer management system ( 100 ). For the calculation of the read rate (Rr) at least an input time measurement (mTa) of an input time instant (Ta) of input of the data unit ( 150 ) in the buffer management system ( 100 ) is required
