Abstract
Provided is a method for font data streaming for time-based video/audio presentations where content is transmitted in small increments and transmission continues while a previously transmitted portion is viewed or played. Different subsets of characters of the same font are assembled together on a device and previously sent characters are reused for rendering subsequent text strings. Font subsets are created to provide only a minimal number of glyphs for the character set coverage, thereby reducing the redundancy of font data transmission and reducing the total number of characters transmitted.
