Abstract

Provided is a technology related to digital broadcast that effectively uses metadata.

A content receiving device for receiving broadcast waves includes: a receiving unit which receives the broadcast waves; an input unit which inputs a user input; a recording unit which records content included in the broadcast waves on a recording medium; and a control unit, and in the content receiving device, character facial data to be information enabling identification of faces of characters of the content is included in the broadcast waves, and the control unit generates searching facial data to be information enabling identification of faces of persons, on the basis of information input to the input unit, and controls recording of the content on the recording medium, on the basis of the searching facial data and the character facial data.

Claims

1. A content receiving device for receiving broadcast waves, comprising:

a receiving unit which receives the broadcast waves;

an input unit which inputs a user input;

a recording unit which records content included in the broadcast waves on a recording medium; and

a control unit,

wherein character facial data to be information enabling identification of faces of characters of the content is included in the broadcast waves, and

the control unit generates searching facial data to be information enabling identification of faces of persons, on the basis of information input to the input unit, and controls recording of the content on the recording medium, on the basis of the searching facial data and the character facial data.

2. The content receiving device according to claim 1, wherein the control unit extracts at least feature data showing features for parts of the faces of the persons from the searching facial data and the character facial data and performs control to select the content recorded on the recording medium, on the basis of the feature data extracted from the searching facial data and the feature data extracted from the character facial data.

3. The content receiving device according to claim 1, further comprising:

an output unit which outputs the recorded content,

wherein the control unit performs control to select the content output from the output unit, on the basis of the searching facial data and the character facial data, when a plurality of contents is recorded on the recording medium.

4. The content receiving device according to claim 1, wherein the character facial data and the searching facial data are still image data enabling recognition of the faces of the persons.

5. A content receiving method in a content receiving device for receiving broadcast waves, comprising:

a reception step of receiving the broadcast waves;

an input step of inputting a user input; and

a recording step of recording content included in the broadcast waves on a recording medium,

wherein character facial data to be information enabling identification of faces of characters of the content is included in the broadcast waves, and

in the recording step, the content is recorded on the recording medium, on the basis of searching facial data to be information enabling identification of faces of persons, which is generated on the basis of information input in the input step, and the character facial data.

6. The content receiving method according to claim 5, further comprising:

an extraction step of extracting at least feature data showing features for parts of the faces of the persons from the searching facial data and the character facial data,

wherein, in the recording step, the content recorded on the recording medium is selected and recorded, on the basis of the feature data extracted from the searching facial data and the feature data extracted from the character facial data.

7. A digital broadcast transmitting and receiving system including a content transmitting device and a content receiving device,

wherein the content transmitting device includes a transmitting unit which transmits broadcast waves,

content and character facial data to be information enabling identification of faces of characters of the content are included in the broadcast waves,

the content receiving device includes a receiving unit which receives the broadcast waves, an input unit which inputs a user input, a recording unit which records the content included in the broadcast waves on a recording medium, and a control unit, and

the control unit generates searching facial data to be information enabling identification of faces of persons, on the basis of information input to the input unit, and controls recording of the content on the recording medium, on the basis of the searching facial data and the character facial data.

8. The digital broadcast transmitting and receiving system according to claim 7, wherein the control unit of the content receiving device extracts at least feature data showing features for parts of the faces of the persons from the searching facial data and the character facial data and performs control to select the content recorded on the recording medium, on the basis of the feature data extracted from the searching facial data and the feature data extracted from the character facial data.
