Abstract

A method and apparatus distribution system in which compressed audio data and relevant information ancillary to the compressed audio, such as data size data, picture information and the text information, are packeted and transmitted or received on the packet basis by time divisional multiplexing.

Claims

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.

2. The distribution system as recited in claim 1, wherein the relevant information includes title information concerning the distributed compressed audio program.

3. The distribution system as recited in claim 2, wherein the advising means displays a title name based on the title information concerning the distributed compressed audio program.

4. The distribution system as recited in claim 3, wherein the advising means displays the title name based on picture information concerning the distributed compressed audio program.

5. The distribution system as recited in claim 1, wherein the relevant information includes picture information concerning the distributed compressed audio program.

6. The distribution system as recited in claim 1, wherein the delay time is longer than a storage time of the compressed audio program stored in the storage means.

7. A distribution method comprising the steps of:

blocking a compressed audio program distributed from an information center and relevant information concerning a data size of the compressed audio program into packets;

transmitting the compressed audio program and the relevant information blocked into packets by the blocking means by time division multiplexing;

receiving the compressed audio program and the relevant information transmitted from the transmitting means by time division multiplexing;

separating the received audio program and the relevant information;

recording the compressed audio program separated by the separation means on a removable recording medium; and

advising a user of the data size of the compressed audio program included in the relevant information;

determining a recordable residual capacity of the removable recording medium;

comparing the data size of the compressed audio program to the recordable residual capacity of the removable recording medium;

issuing an alarm if the data size of the compressed audio program exceeds the recordable residual capacity of the removable recording medium;

storing in a storage area the compressed audio program recorded on the removable recording medium;

detecting a recording capacity of the storage area; and

transmitting a first transmission of a pre-set audio program and after a delay time transmitting a second transmission of the pre-set audio program,

wherein if the compressed audio program stored in the storage area exceeds a predetermined size, switching reception to receive the second transmission of the pre-set audio program which is stored in the storage area.

8. A reception apparatus for receiving data obtained by blocking a distributed compressed audio program and relevant information concerning a data size of the compressed audio program into packets and by transmitting the packets of the compressed audio program and the relevant information from an information center by time division multiplexing;

comprising;

reception means for receiving the compressed audio program and the relevant information concerning the compressed audio program transmitted from the information center by time division multiplexing;

separating means for separating the compressed audio program and the relevant information received by the reception means;

recording means for recording on a recording medium the compressed audio program separated by the separating means; and

advising means for advising a user of the data size of the compressed audio program included in the relevant information;

determining means for determining a recordable residual capacity of the removable recording medium;

comparator means for comparing the data size of the compressed audio program to a recordable residual capacity of the removable recording medium;

storage means for temporarily storing the compressed audio program separated by the separating 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 removable recording medium,

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.

9. A reception method for receiving data obtained by distributing and blocking a compressed audio program and relevant information concerning a data size of the compressed audio program into packets and by transmitting the packets of the compressed audio program and the relevant information from an information center by time division multiplexing, comprising the steps of:

receiving the compressed audio program and the relevant information concerning the distributed audio program transmitted from the information center by time division multiplexing;

separating the received compressed audio program and the relevant information;

recording the compressed audio program separated by the separating means on a removable recording medium; and

advising a user of the data size of the compressed audio program included in the relevant information;

determining a recordable residual capacity of the removable recording medium;

comparing the data size of the compressed audio program to a recordable residual capacity of the removable recording medium;

issuing an alarm if the data size of the compressed audio program exceeds the recordable residual capacity of the removable recording medium;

storing in a storage area the compressed audio program recorded on the removable recording medium;

detecting a recording capacity of the storage area; and

transmitting a first transmission of a pre-set audio program and after a delay time transmitting a second transmission of the pre-set audio program,

wherein if the compressed audio program stored in the storage area exceeds a predetermined size, switching reception to receive the second transmission of the pre-set audio program which is stored in the storage area.
