Abstract

A multiplexing digital broadcast system includes a receiving terminal; and a broadcasting station. The receiving terminal includes: a receiving side recording device demodulating a specification digital data selectively specified from a multiplexing digital data transmitted by the broadcasting station to record; a receiving side table recording a position in a data string corresponding to a data unit of the specification digital data in which a demodulation ended in failure; and a communicating device transmitting the position in the data string to the broadcasting station, and wherein the broadcasting station includes: a broadcasting station side recording device recording an original data corresponding to the multiplexing digital data; and a supplemental data transmitting device extracting the specification digital data corresponding to the position in the data string from the original data to transmit to the receiving terminal.

Claims

1. A multiplexing digital broadcast system, comprising:

a receiving terminal; and

a broadcasting station, and

wherein said receiving terminal includes;

a receiving side recording device demodulating a specification digital data selectively specified from a multiplexing digital data transmitted by said 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

wherein said broadcasting station includes;

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

a supplemental data transmitting device extracting said specification digital data corresponding to said position in said data string from said original data to transmit to said receiving terminal.

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

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 is started with a supplemental data that is said specification digital data transmitted from said supplemental data transmitting device and an end time when said supplement is ended 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, and

wherein said signal 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 is 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 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 is 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 receiving side table records a record position of a data recorded on said receiving side recording device to play back a supplemental data that is said specification digital data transmitted from said supplemental data transmitting device instead of playing back said data recorded on said receiving side recording device.

10. The multiplexing digital broadcast system according to claim 8, wherein said timing position includes a start time when a supplement is started with a supplemental data that is said specification digital data transmitted from said supplemental data transmitting device and an end time when said supplement is ended 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 is 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.

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

12. A multiplexing digital broadcast method, comprising:

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

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

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

re-broadcasting said specification data corresponding to said position in said data string to said receiving side by said broadcasting station.

13. The multiplexing digital broadcast method according to claim 12, wherein said re-broadcasting includes:

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

adding an ID to specify said receiving side and an ID to specify said specification data to said specification data; and

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

multiplexing said specification data.

14. A multiplexing digital broadcast method, comprising:

providing a stream data; and

multiplexing data except usual program data in said stream data to broadcast.

15. The multiplexing digital broadcast method according to claim 14, wherein said data except said usual program data is a re-broadcast data that is not demodulated on said receiving side.

16. A computer readable recording medium for recording a program for a process, comprising:

transmitting to a broadcasting source a position in a data string of a data except a usual program data of a specification digital data selectively specified from a digital data except usual program data multiplexed in a stream data to be broadcasted from said broadcasting source in which a demodulation ended in failure at a received side.
