Title: Data transmitting system/method and data transmitting device/method
Inventor: NOMURA TAKASHI
IPC: H04L12/40
Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To reduce overhead and to efficiently transmit data by generating an interruption signal having a scheduling period longer than a prescribed transmission period and controlling the transmission of data for every prescribed transmission period based on data amount transmittable within one scheduling period unit. SOLUTION: When the timer interruption signal is generated while having the period of timer interruption (S701), a parameter showing the total number of isochronous cycles within the scheduling period is initialized (S702). The number of isochronous packets which can be transmitted per scheduling period is added (S707). Thus, the interruption signal is generated while having the scheduling period and the transmission of data is controlled for every prescribed transmission period based on data quantity which can be transmitted within one scheduling period unit. Consequently, over head in data transmission is reduced and transmission efficiency is improved.
