Embodiment Construction

[0032]Generally speaking, an iTV broadcast includes multiple files, some of which are applications, usually composed of Java executable code, and some are data files, including the above-mentioned font files. Applications usually indicate the fonts used to run the application. In order to receive and display the iTV application on a TV set, the font must be available from the set-top box, be the default font or downloaded and stored in the STB font, or the font must be included as a file in the broadcast. When the application is stored on a storage medium for later playback, the fonts used by the application must also be stored. According to the present invention, the fonts are stored in the font library of the storage medium instead of being stored together with the specific application using them. Therefore, there is no need to modify the application program, for example to point to a specific font file location. Required font files are stored in a separate location of the...

Abstract

The present invention provides a method (49, 55) of handling fonts in a recorder or a playback-recorder for interactive television. Fonts are stored on a recordable storage medium (220), wherein the fonts are part of a downloaded interactive television application. When recording, the downloaded fonts are stored separate from the application, preferably in a font library on the recordable storage medium, which preferably is a removable medium, preferably an optical storage medium. Each font is only stored in one copy, even when a plurality of applications on the storage medium need that font for running. When playing back the application from the storage medium, indicating information is provided on which fonts form the storage medium in the font library are required for playback of said application from said storage medium. Thus multiple storage of fonts is prevented, minimising needed storage space on the storage medium.

Description

technical field [0001] The present invention relates generally to the field of interactive television, and more particularly to the recording of interactive television content, and more particularly to fonts handled in the field of interactive television content recording. Background technique [0002] Interactive television (iTV) is becoming more and more popular. An example of interactive television is the Multimedia Home Platform (MHP), a Digital Video Broadcasting (DVB) standard that attempts to combine digital television (DTV) with human-machine conversation and access to the Internet and the World Wide Web. DTV service providers offer a large number of audio-visual (A / V) television programs and a large number of applications that allow the viewer / user to interact with the television and its content. The application is broadcast with the A / V content and is executed in a television set suitable for the task or in a stand-alone set-top box (STB). [0003] Similar to tod...
