Digital broadcast receiving apparatus, method, and program
First Claim
1. A digital broadcast receiving apparatus connected to an external storage apparatus, comprising:
- a first storage unit;
a first control unit operable to store into the first storage unit a partial transport stream which is contained in a transport stream sent from outside and includes (i) elementary streams constituting a broadcast program and (ii) control information for controlling the broadcast program, and to create, from the control information, broadcast program attachment information which is used in outputting the partial transport stream to the external storage apparatus;
a second storage unit operable to store the created broadcast program attachment information with indication of a correspondence with the partial transport stream stored in the first storage unit;
a second control unit operable to, in accordance with the broadcast program attachment information, give an instruction to update the control information in the first storage unit; and
an interface operable to receive the update instruction from the second control unit, read the partial transport stream from the first storage unit, update the control information contained in the read partial transport stream, and output the partial transport stream with the updated control information, to the external storage apparatus.

Abstract
A digital broadcast receiving apparatus that receives a TS and stores into an HDD a partial TS which contains a broadcast program selected by a TS decoder. A CPU creates broadcast program attachment information from PMT or the like in which control information of the selected broadcast program is written, and stores the broadcast program attachment information into a flash ROM. The broadcast program attachment information contains copy control information, bit rate information, and PIDs of CAT and EMM. When outputting the partial TS to an external VCR for copying, the digital broadcast receiving apparatus refers to the broadcast program attachment information, and gives instructions as necessary to update PMT or set the recording mode in the VCR, prior to the output of the partial TS to the external VCR.

10. A digital broadcast receiving method for use in a digital broadcast receiving apparatus connected to an external storage apparatus, comprising:
-
a first control step for storing into a first storage area a partial transport stream which is contained in a transport stream sent from outside and includes (i) elementary streams constituting a broadcast program and (ii) control information for controlling the broadcast program, and creating, from the control information, broadcast program attachment information, which is used in outputting the partial transport stream to the external storage apparatus, and storing into a second storage area the created broadcast program attachment information with indication of a correspondence with the partial transport stream stored in the first storage area;
a second control step for, in accordance with the broadcast program attachment information, giving an instruction to update the control information in the first storage area; and
an outputting step for receiving the update instruction, reading the partial transport stream from the first storage area, updating the control information contained in the read partial transport stream, and outputting the partial transport stream with the updated control information, to the external storage apparatus.

11. A digital broadcast receiving program applied to a digital broadcast receiving apparatus which includes a computer connected to an external storage apparatus, the digital broadcast receiving program causing the computer to execute:
-
a first control step for storing into a first storage area a partial transport stream which is contained in a transport stream sent from outside and includes (i) elementary streams constituting a broadcast program and (ii) control information for controlling the broadcast program, and creating, from the control information, broadcast program attachment information, which is used in outputting the partial transport stream to the external storage apparatus, and storing into a second storage area the created broadcast program attachment information with indication of a correspondence with the partial transport stream stored in the first storage area;
a second control step for, in accordance with the broadcast program attachment information, giving an instruction to update the control information in the first storage area; and
an outputting step for receiving the update instruction, reading the partial transport stream from the first storage area, updating the control information contained in the read partial transport stream, and outputting the partial transport stream with the updated control information, to the external storage apparatus.
