Wireless transmitting method
First Claim
1. A wireless transmitting method, comprising the steps of:
- forming a frame having a predetermined time period;
placing a stream transmission period and an asynchronous transmission period in the frame, wherein the stream transmission period includes a predetermined number of time slots for transmitting data;
allocating isochronous data to the time slots;
transmitting the isochronous data in the stream transmission period; and
transmitting asynchronous data in the asynchronous transmission period, wherein the stream transmission period and the asynchronous transmission period are adaptively varied in length so that when there is no isochronous data to be transmitted, the asynchronous transmission period is expanded to occupy the entire stream transmission period resulting in only the asynchronous data being transmitted in the frame.

Abstract
A wireless transmitting method, for use with digital electronic unit including the steps of forming a frame having a predetermined time period, placing a stream transmission area SPA and an asynchronous transmission area ASYNCA in the frame, the stream transmission area SPA having a predetermined number of time slots SL1, SL2, . . . for transmitting data, allocating isochronous data to the time slots, transmitting the isochronous data in the stream transmission area SPA, transmitting asynchronous data in the asynchronous transmission area ASYNCA, and changing the allocation of the time slots and widening the asynchronous transmission area ASYNCA of the frame so as to gather the asynchronous transmission area ASYNCA when a time slot is unallocated.
