Abstract

A broadcasting system which can automatically record only contents matching needs of a user and effectively save a capacity of storing means. First, with a transmission apparatus, the broadcasting system sends contents data and classification identifying information, which corresponds to and indicates details of a data part considered to have details different from each other forming the contents data as one program. In addition to this, on a recording apparatus side, the broadcasting system detects matching with the received classification identifying information and designated classification identifying information such that only a data part corresponding to classification identifying information, for which matching has been detected in this way, of the received contents data is recorded in storing means. Alternatively, the broadcasting system makes it possible to set required data as key information according to an operation. Then, the broadcasting system performs detection for a data part, which matches the set key information, of the received contents data such that, in response to the data part matching the key information being detected from the received contents data in this way, only a required data part including and following this data part is recorded in the storing means.

Claims

1. A broadcasting system which comprises at least a transmission apparatus for sending contents data and a recording apparatus which can record the contents data, characterized in that

the transmission apparatus comprises:

contents sending means which sends the contents data;

classification information generating means which generates predetermined classification identifying information corresponding to a data part considered to have details of contents different from each other in the contents data as one program; and

classification information sending means which sends the corresponding classification information generated by the classification information generating means so as to associates the classification identifying information with the data part which should be sent by the contents sending means, and that

the recording apparatus comprises;

receiving means which receives the contents data and the classification identifying information;

detecting means which detects matching of the classification identifying information received by the receiving means and classification identifying information designated in advance; and

recording control means which performs control such that only a data part corresponding to classification identifying information, for which matching has been detected by the detecting means, of the contents data received by the receiving means is recorded in storing means.

2. A recording apparatus characterized by comprising:

receiving means which receives contents data and classification identifying information which corresponds to and indicates details of a data part considered to have details different from each other forming the contents data as one program;

detecting means which detects matching of the classification identifying information received by the receiving means and classification identifying information designated in advance; and

recording control means which performs control such that only a data part corresponding to classification identifying information, for which matching has been detected by the detecting means, of the contents data received by the receiving means is recorded in storing means.

3. The recording apparatus according to claim 2, characterized by further comprising:

classified deleting means which can delete data parts other than a data part corresponding to designated classification identifying information of contents data stored in the storing means.

4. The recording apparatus according to claim 2, characterized in that

the recording control means is adapted to, when the data part corresponding to the classification identifying information for which matching has been detected by the detecting means is recorded in the storing means anew, delete required data out of data which is associated with the same classification identifying information as the data part, which should be recorded anew, and is considered to be stored in the storing means.

5. The recording apparatus according to claim 2, characterized in that,

in designating the classification identifying information in advance, the classification identifying information is designated by selecting classification identifying information from a classification identifying information designation screen displayed on a display screen.

6. The recording apparatus according to claim 5, characterized in that,

the classification identifying information is designated by selecting classification identifying information by movement of a cursor from the classification identifying information designation screen displayed on the display screen.

7. The recording apparatus according to claim 2, characterized in that,

designation of the classification identifying information designated in advance is performed by remote control through a portable terminal device via a network.

8. The recording apparatus according to claim 2, characterized in that,

when the detected classification identifying information has been changed, the recording control means performs control such that recording with respect to the storing means is finished.

9. A recording method comprising:

reception processing for receiving contents data and classification identifying information which corresponds to and indicates details of a data part considered to have details different from each other forming the contents data as one program;

detection processing for detecting matching of the classification identifying information received by the reception processing and classification identifying information designated in advance; and

recording control processing for recording only a data part corresponding to classification identifying information, for which matching has been detected by the detection processing, of the contents data received by the reception processing in storing means.

10. A program characterized by causing a recording apparatus to execute:

reception processing for receiving contents data and classification identifying information which corresponds to and indicates details of a data part considered to have details different from each other forming the contents data as one program;

detection processing for detecting matching of the classification identifying information received by the reception processing and classification identifying information designated in advance; and

recording control processing for recording only a data part corresponding to classification identifying information, for which matching has been detected by the detection processing, of the contents data received by the reception processing in storing means.

11. A recording medium having recorded therein a program for causing a recording apparatus to execute:

reception processing for receiving contents data and classification identifying information which corresponds to and indicates details of a data part considered to have details different from each other forming the contents data as one program;

detection processing for detecting matching of the classification identifying information received by the reception processing and classification identifying information designated in advance; and

recording control processing for recording only a data part corresponding to classification identifying information, for which matching has been detected by the detection processing, of the contents data received by the reception processing in storing means.

12. A recording apparatus characterized by comprising:

receiving means which can receive contents data as a broadcasting program;

key information setting means which can set required data as key information according to an operation;

detecting means which detects a data part matching the key information, which has been set by the key information setting means, from the contents data received in the receiving means; and

recording control means which performs control such that only a required data part including and following the data part, for which matching has been detected by the detecting means, of the contents data received by the receiving means is recorded in a storage medium.

13. The recording apparatus according to claim 12, characterized in that the key information setting means is constituted so as to be capable of setting image data as the key information.

14. A recording method comprising:
