Abstract

In case the digital broadcasting wave contains printable contents data, the invention multiplexes a message, a mark or an icon on the display screen of the currently viewed program or outputs an audio message to inform the user of the presence of such contents data. The invention prevents a situation where the contents data cannot be or are not printed even though the data are transmitted, and allows the user to correctly prepare the type or number of sheets in advance in the printer.

Claims

1. A television broadcasting data receiving apparatus, comprising:

a receiving unit adapted to receive television broadcasting data which includes image data of a broadcasting program, printing data related to the broadcasting program, and print additional information for notifying a user of an attribute of the printing data;

a print controlling unit adapted to output the printing data included in the television broadcasting data received by said received unit to a printing apparatus;

an acquiring unit adapted to extract the print additional information from the television broadcasting data received by said receiving unit; and

a display control unit adapted to generate display data on the basis of the print additional information acquired by said acquiring unit and output, to a display device, the display data together with the image data included in the television broadcasting data received by said receiving unit,

wherein the print additional information included in the television broadcasting data includes at least one of information indicating a print sheet size of the printing data.

2. An apparatus according to claim 1, further comprising:

an accepting unit adapted to accept a printing instruction from a user;

wherein said print controlling unit is adapted to perform the output of the printing data to the printing apparatus on the basis of the printing instruction,

wherein the print additional information includes information indicating whether there is the printing data, and

wherein said accepting unit accepts the printing instruction from the user in a period during which said display controlling unit effects a display which indicates that there is the printing data, on the basis of the print additional information.

3. An apparatus according to claim 1, further comprising:

an accepting unit adapted to accept a storing instruction from a user; and

a storage controlling unit adapted to store the printing data in a storage unit on the basis of the storing instruction,

wherein the print additional information includes information indicating whether the printing data can be stored, and

wherein said accepting unit accepts the storing instruction from the user in a period during which said display controlling unit effects a display which indicates that the printing data can be stored, on the basis of the print additional information.

4. An apparatus according to claim 1, wherein the print additional information includes information for specifying a transmission period of time of the printing data, and wherein said display controlling unit displays a print execution time of the printing data on the basis of the transmission period.

5. An apparatus according to claim 1, wherein in case that there are a plurality of types of print additional information to be displayed by said display device, said display controlling unit displays the respective display data associated with the plurality of types of print additional information so that the display of each of the respective display data is switched over therebetween at a predetermined time interval.

6. A control method of a television broadcasting data receiving apparatus, comprising:

a receiving step of receiving television broadcasting data which includes image data of a broadcasting program, printing data related to the broadcasting program, and print additional information for notifying a user of an attribute of the printing data;

a print controlling step of outputting the printing data included in the television broadcasting data received in said receiving step to a printing apparatus;

an acquiring step of extracting the print additional information from the television broadcasting data received in said receiving step; and

a display control step of generating display data on the basis of the print additional information acquired in said acquiring step and outputting, to a display device, display data together with the image data included in the television broadcasting data received in said receiving step,

wherein the print additional information included in the television broadcasting data includes at least one of information indicating a print sheet size of the printing data, information indicating the number of the print sheets of the printing data, and information indicating the type of the printing data.

7. A method according to claim 6, further comprising:

an accepting step of accepting a printing instruction from a user;

wherein said print controlling step performs the output of the printing data to the printing apparatus on the basis of the printing instruction,

wherein the print additional informational includes information indicating whether there is the printing data, and

wherein said accepting step includes accepting the printing instruction from the user in a period during which performance of said display controlling step effects a display which indicates that there is the printing data, on the basis of the print additional information.

8. A method according to claim 6, further comprising:

an accepting step of accepting a storing instruction from a user; and

a storage controlling step of storing the printing data in a storage unit on the basis of the storing instruction,

wherein the print additional information includes information indicating whether the printing data can be stored, and

wherein said accepting step includes accepting the storing instruction from the user in a period during which performance of said display controlling step effects a display which indicates that the printing data can be stored, on the basis of the print additional information.

9. A method according to claim 6, wherein the print additional information includes information for specifying a transmission period of time of the printing data, and wherein said display controlling step includes displaying a print execution time of the printing data on the basis of the transmission period.

10. A method according to claim 6, wherein, in a case in which there are a plurality of types of print additional information to be displayed by said display device, said display controlling step includes displaying the respective display data associated with the plurality of types of print additional information so that the display of each of the respective display data is switched over therebetween at a predetermined time interval.

11. A computer-readable recording medium which stores a computer-executable program for causing a television broadcasting receiving apparatus to execute the control method set out in claim 6.
