1. A distribution system comprising:blocking means for forming into packets a compressed audio program distributed from an information center and relevant information concerning a data size of the compressed audio program; transmitting means for transmitting the compressed audio program and the relevant information formed into packets by the blocking means by time division multiplexing; reception means for receiving the compressed audio program and the relevant information transmitted from the transmitting means by time division multiplexing; separation means for separating the compressed audio program from the relevant information for each packet received by the reception means; recording means for recording on a recording medium the compressed audio program separated by the separation means; advising means for advising a user of the data size of the compressed audio program included in the relevant information separated by the separation means; determining means for determining a recordable residual capacity of the recording medium; comparator means for comparing the data size of the compressed audio program included in the relevant information separated by the separation means to the recordable residual capacity of the recording medium; and storage means for temporarily storing the compressed audio program separated by the separation means, wherein the recording means records the compressed audio program read out from the storage means; and detecting means for detecting a recording capacity of the storage means, wherein the advising means issues an alarm if, as a result of comparison by the comparator means, the data size of the compressed audio program exceeds the recordable residual capacity of the recording medium and wherein the transmitting means transmits a first transmission of a pre-set audio program and after a delay time the transmitting means transmits a second transmission of the pre-set audio program, and wherein if the compressed audio program stored in the storage means exceeds a predetermined size, the reception means switches to receive the second transmission of the pre-set audio program which is stored in the storage means.
