## Abstract

An apparatus for processing texts in a digital broadcast receiver and method thereof are disclosed. The present invention includes a text extracting unit extracting the texts from contents of data inputted to the digital broadcast receiver and a text processing unit processing the extracted texts. Accordingly, a user can efficiently acquire the information, a user can acquire accurate and summarized information from a digital broadcast video, a storage device can be efficiently used, a computer or other mobile terminals can use the contents of a broadcast program, and a load of hardware can be reduced.

## Claims

### Claim 1

An apparatus for processing texts in a digital broadcast receiver, comprising:
a text extracting unit extracting the texts from contents of data inputted to the digital broadcast receiver; and
a text processing unit processing the extracted texts.

### Claim 2 (depends on 1)

The apparatus of claim 1, the text processing unit comprising a text converting unit converting each of the extracted texts to a file format to process the converted file.

### Claim 3 (depends on 2)

The apparatus of claim 2, further comprising a user interface unit outputting as a user signal requirements received from a user,
wherein the text converting unit converts each of the extracted texts to the file format determined corresponding to the user signal.

### Claim 4 (depends on 1)

The apparatus of claim 1, the text processing unit comprising a keyword searching unit searching the text associated with a keyword only from the extracted texts to process the searched result.

### Claim 5 (depends on 4)

The apparatus of claim 4, wherein the keyword searching unit converts each of the extracted texts to an ASCII code and searches the ASCII code for the texts associated with the keyword only.

### Claim 6 (depends on 4)

The apparatus of claim 4, further comprising a user interface unit outputting as a user signal requirements received from a user,
wherein the keyword searching unit decides at least one of the keyword and an extent associated with the keyword as the text associated with the keyword corresponding to the user signal and searches the texts using the decided result.

### Claim 7 (depends on 4)

The apparatus of claim 4, the text processing unit comprising a text control unit reproducing or outputting externally the extracted texts.

### Claim 8 (depends on 7)

The apparatus of claim 7, further comprising a storage unit storing the extracted texts,
wherein the text control unit stores the extracted texts in the storage unit.

### Claim 9 (depends on 8)

The apparatus of claim 8, further comprising a user interface unit outputting as a user signal requirements received from a user,
wherein the text control unit determines at least one of a storage of the extracted text, an external output of the extracted text and a reproduction of the extracted text, corresponding to the user signal.

### Claim 10 (depends on 1)

The apparatus of claim 1, further comprising a contents extracting unit extracting the corresponding contents by decoding the data inputted to the digital broadcast receiver, the contents extracting unit outputting the extracted contents to the text extracting unit.

### Claim 11 (depends on 10)

The apparatus of claim 10, wherein the contents extracted by the contents extracting unit comprise at least one of caption contents, subtitle contents, teletext contents, data broadcast contents and ticker data contents.

### Claim 12 (depends on 11)

The apparatus of claim 11, the contents extracting unit comprising:
a caption processing unit extracting the caption contents by decoding the data;
a subtitle processing unit extracting the subtitle contents by decoding the data;
a teletext processing unit extracting the teletext contents by decoding the data;
a data broadcast processing unit extracting the data broadcast contents by decoding the data; and
a ticker processing unit extracting the ticker data contents by decoding the data.

### Claim 13 (depends on 10)

The apparatus of claim 10, further comprising a buffer temporarily storing the extracted contents inputted from the contents extracting unit, the buffer outputting a stored result to the text extracting unit.

### Claim 14

A method of processing texts in a digital broadcast receiver, comprising the operations of:
extracting the texts from contents of data inputted to the digital broadcast receiver; and
processing the extracted texts.

### Claim 15 (depends on 14)

The method of claim 14, the text processing operation comprising the operation of converting each of the extracted texts to a file format to process the converted file.

### Claim 16 (depends on 14)

The method of claim 14, wherein the file format is decided by a user.

### Claim 17 (depends on 14)

The method of claim 14, the text processing operation comprising the operation of searching the text associated with a keyword only from the extracted texts to process the searched result.

### Claim 18 (depends on 17)
