Abstract:
1. A method comprising: receiving a description file of a multimedia scene at a radio communication terminal; identifying within the description file of the multimedia scene each of a first font management command referencing a first character font to be used for rendering a first portion of the multimedia scene and a second font management command referencing a second character font to be used for rendering a second portion of the multimedia scene; identifying from the first font management command first parameters associated with the first character font including: identifying from the second font management command a second parameter associated with the second character font including properties of the second character font; searching for the first character font at the indicated address, and downloading the first character font from the indicated address; rendering, on the radio communication terminal, the first portion of the multimedia scene using the first character font; after rendering the first character font within the multimedia scene, preventing further storage of the first character font based on the intellectual property right associated with the first character font, such that further use of the downloaded first character font by the radio communication terminal within another multimedia scene is prevented; determining based on the identified second parameter that no address was provided in the second font management command for downloading the second character font; in response to the determination that no address was provided for downloading the second character font, identifying a substitute character font from at least one other character font already stored in the radio communication terminal by determining that the properties of the second character font match properties of the substitute character font more closely than properties of remaining ones of the at least one other character font already stored in the radio communication terminal; and rendering, on the radio communication terminal, the second portion of the multimedia scene using the substitute character font; wherein if a particular font of the at least one other character font already stored in the radio communication terminal has a value for a length of life parameter indicating that the particular font is to remain in memory of the radio communication terminal, but the particular font occupies a particular portion of the memory such that the particular font prevents the downloading of the first character font from the indicated address, then the particular font is deleted from the particular portion of the memory of the radio communication terminal in order to be replaced by the first character font.
