a communicating device configured to transmit said position in said data string to said broadcasting station, and

wherein said broadcasting station includes:

a broadcasting station side recording device configured to record an original data corresponding to said multiplexing digital data; and

a supplemental data transmitting device configured to extract said specification digital data corresponding to said position in said data string from said original data and to transmit to said receiving terminal, and

wherein said broadcasting station multiplexes said supplemental data with said multiplexing digital data.

2. The multiplexing digital broadcast system according to claim 1 , wherein said supplemental data transmitting device multiplexes said specification digital data to retransmit.

3. The multiplexing digital broadcast system according to claim 1 , wherein said receiving terminal further includes:

an input device through which a receiving side user inputs a signal, and

wherein said signal includes:

a signal to play back said specification digital data recorded on said receiving side recording device; and

a selection signal to select said specification digital data.

4. The multiplexing digital broadcast system according to claim 1 , wherein said position in said data string corresponds to a timing position, and said timing position is noted on said receiving side table.

5. The multiplexing digital broadcast system according to claim 4 , wherein said timing position includes a start time when a supplement starts with a supplemental data that comprises said specification digital data transmitted from said supplemental data transmitting device and an end time when said supplement ends with said supplemental data.

6. The multiplexing digital broadcast system according to claim 1 , wherein said receiving terminal further includes:

an input device through which a receiving side user inputs a signal,

wherein said signal is selected from a group which includes:

a signal to play back said specification digital data recorded on said receiving side recording device;

a selection signal to select said specification digital data; and

a transmission start signal to start a transmission of a supplemental data that comprises said specification digital data transmitted from said supplemental data transmitting device, and

wherein said broadcasting station sends said supplemental data based on said transmission start signal.

7. The multiplexing digital broadcast system according to claim 1 , wherein said receiving side table records said position in said data string of said specification digital data in which said demodulation ended in failure as a playback stop position to stop playing back a data recorded on said receiving side recording device.

8. The multiplexing digital broadcast system according to claim 7 , wherein said receiving side table records a record position of a data recorded on said receiving side recording device to play back a supplemental data that comprises said specification digital data transmitted from said supplemental data transmitting device instead of playing back said data recorded on said receiving side recording device.

9. The multiplexing digital broadcast system according to claim 7 , wherein said timing position includes a start time when a supplement starts with a supplemental data that comprises said specification digital data transmitted from said supplemental data transmitting device and an end time when said supplement ends with said supplemental data, and

wherein, when a timing information of a played back one of said data recorded on said receiving side recording device which is not a supplemental data that comprises said specification digital data transmitted from said supplemental data transmitting device corresponds to said end time, a read out position of said played back one is changed to said playback stop position.

10. The multiplexing digital broadcast system according to claim 1 , wherein said receiving side table records a record position of a data recorded on said receiving side recording device to play back a supplemental data that comprises said specification digital data transmitted from said supplemental data transmitting device instead of playing back said data recorded on said receiving side recording device.

11. The multiplexing digital broadcast system according to claim 10 , wherein said timing position includes a start time when a supplement starts with a supplemental data that comprises said specification digital data transmitted from said supplemental data transmitting device and an end time when said supplement ends with said supplemental data, and

wherein, when a timing information of a played back one of said data recorded on said receiving side recording device which is not a supplemental data that comprises said specification digital data transmitted from said supplemental data transmitting device corresponds to said start time, a read out position of said played back one is changed to said record position.

12. The multiplexing digital broadcast system according to claim 1 , wherein said specification digital data comprises digital audiovisual data.

13. The multiplexing digital broadcast system according to claim 1 , wherein said specification digital data comprises Mpeg-ts (ISO/IEC 13818-1).

14. A multiplexing digital broadcast method, comprising:

demodulating a specification digital data selectively specified from a multiplexing digital broadcast data broadcasted by a broadcasting station on a receiving terminal to record;

recording a position in a data string of said specification digital data in which said demodulating ended in failure on said receiving terminal;

communicating said position in said data string to said broadcasting station; and

retransmitting said specification data corresponding to said position in said data string to said receiving terminal by multiplexing said specification digital data with said multiplexing digital broadcast data broadcast by said broadcasting station.

15. The multiplexing digital broadcast method according to claim 14 , wherein said retransmitting includes:

extracting from a data received by said broadcasting station said specification digital data corresponding to said position in said data string transmitted from said receiving terminal;

adding an ID to specify said receiving terminal and an ID to specify said specification digital data;

inserting said specification digital data into a frequency band of said multiplexing digital broadcast data; and

multiplexing said specification digital data with said multiplexing digital broadcast data for retransmitting.

16. A component for a multiplex digital broadcast system, said component comprising one of:

a receiving terminal comprising:

a receiving side recording device demodulating a specification digital data selectively specified from a multiplexing digital data transmitted by a broadcasting station to record;

a receiving side table recording a position in a data string corresponding to a data unit of said specification digital data in which a demodulation ended in failure; and

a communicating device transmitting said position in said data string to said broadcasting station, and

a broadcasting station comprising:

a broadcasting station side recording device recording an original data corresponding to said multiplexing digital data; and
