Image display device in digital TV
DCFirst Claim
1. A digital television having a display, comprising:
- a receiving part configured to receive at least one of digital image data and analog image data;
a data processing part configured to execute bit map conversion and format-conversion for text data to be displayed on the display;
a memory configured to store the bit map data obtained according to the bit map conversion in the data processing part and image data inputted from an arbitrary receiving part;
an image outputting part configured to read image data from the memory; and
a display processing part configured to mix image data read from the image outputting part and the bit map data converted in format by the data processing part.

Abstract
Disclosed is an image display device in a digital TV that is capable of carrying out the conversion into various kinds of resolution by using single bit map data in the digital TV. The image display device includes: a data processing part for executing bit map conversion, compression, restoration and format-conversion for text data; a memory for storing the bit map data obtained according to the bit map conversion and compression in the data processing part and image data inputted from an arbitrary receiving part, the receiving part receiving one of digital image data and analog image data; an image outputting part for reading the image data from the memory; and a display processing part for mixing the image data read from the image outputting part and the bit map data converted in format from the data processing part. Therefore, the image display device according to the present invention can convert text data in such a manner as to correspond with various resolution, carry out the compression for bit map data, thereby reducing the memory space, and support text data of an HTML format, thereby providing the image with the text data of various shapes.
