METHOD AND APPARATUS FOR FORMATTING DATA FOR TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for formatting data of various types into an original structure for transmission in various rates in digital communications.

SOLUTION: Data for a transmission format may also be audio data supplied by a vocoder (14) or secondary traffic of a different type. Data structured into a frame of a predetermined time cycle are transmitted by a microprocessor (18). The data frame is structured into one of several data rates according to data. Vocoder data are supplied in one of several rates by the vocoder (14) and structured with the frame according to a predetermined format. The frame may also be formatted into a highest frame data rate while sharing vocoder data including non-vocoder data. Non-vocoder data of a different type may also be structured into the highest frame data rate. Additional control data are supplied to the data frame and may also be effectively utilized for various aspects of recovery in transmission and reception.
