Variable data rate indication method of the subsequent frame for the variable data rate systems

摘要

(57) in a system in which the frame boundaries are synchronized at a fixed has a [summary] variable data rate, is inserted into the frame of the current indication of the data rate of the next frame transmitter (10). When assembling the current frame for encoding, station modem (18), vocoder CPU (22) and (20), according to the appropriate data rate information for the subsequent frame, then the station modem (18) Insert a rate instruction for the frame. Receiver (30) side, and decodes the number of time (38) is the rate of each frame after the first frame receiving station modem to determine the appropriate data rate for all frames rather find.
