TRANSMISSION CHANNEL ERROR DETECTION CODE ADDITION APPARATUS AND ERROR DETECTION APPARATUS

摘要

A transmission channel error detection code addition apparatus includes a division section, calculation section, and transmission section. The division section divides a code bitstream obtained from input information having a coding unit time length which is an N integer multiple (N >= 2) of an error detection unit time length into N bitstreams. The calculation section calculates an error detection code of each divided bitstream output from the division section. The transmission section sequentially transmits each divided bitstream output from the division section and the error detection code output from the calculation section in correspondence with each divided bitstream.
