    摘要: Text is rendered to a television screen using only the alpha channel. This is accomplished by delaying blending with underlying video until the end of the process to thereby preserve the alpha channel information. Glyphs are used to graphically represent character data in the text to be rendered. Glyphs can be stored in a character texture. In addition, the glyphs can be contained in rectangles having identifiable locations in the character texture. The rectangles can have sizes dependent upon the glyph the rectangle contains.
