US 2010/0164958 A1 · DISPLAY METHOD OF ON SCREEN DISPLAY (OSD) AND DISPLAY SYSTEM THEREOF

Abstract

A display method of an OSD and a display system are provided herein. In the display method, a plurality of symbols are respectively compressed into a plurality of codewords according to an encoding process, and the codewords are stored in a memory module. A plurality of index values respectively corresponding to the symbols are established in a codebook and the codebook is stored in the memory module, wherein the index values are address information of storing the codewords in the memory module. The index value corresponding to a designation symbol of the symbols is searched out from the codebook according to an input command corresponding to the designation symbol, and a decoding process is performed on the codeword corresponding to the designation symbol from the memory module for displaying the designation symbol on the display. Therefore, a storage space of the memory module is reduced by compressing the symbols.

Dependent claims

A display method of an on screen display (OSD), comprising:

compressing a plurality of symbols of the OSD into a plurality of codewords according to a first encoding process, respectively, and storing the codewords in a memory module;
establishing a codebook in the memory module, wherein the codebook comprising a plurality of index values respectively corresponding to the symbols, and the index values are address information of storing the codewords in the memory module;
searching out the index value corresponding to a designation symbol of the symbols from the codebook according to an input command corresponding to the designation symbol;
searching out the codeword corresponding to the designation symbol from the memory module according to the searched index value;
and
performing a first decoding process corresponding to the first encoding process on the codeword corresponding to the designation symbol, and displaying the designation symbol on a screen.
