In multi-channel PCM music broadcasting system, a plurality of blocks are time division multiplexed, each block having at least one music channel for a PCM formatted music signal and having an independent operation mode information. The time division multiplexed signal modulates a carrier, and a plurality of time division multiplexed signals each having a frequency shift from the carrier are frequency division multiplexed for transmission. The operation mode information for the plurality of blocks is collectively inserted in a time division multiplexed frame, an operation mode information for the plurality of time division multiplexed signals each having a frequency shift is exchanged among a plurality of time division multiplexing units, and both the operation mode informations are commonly inserted in the time division multiplexed frame for transmission. Upon designation of a music channel at a receiver side, both the operation mode informations are referred to to select a particular frequency and block including the designated music channel.
