Font Fusion: The Best Text Renderer on the Market
for Digital Television

High-quality font rendering in a small footprint
Bitstream's font rendering technology provides the best possible text output for digital or analog TV of any font solution on the market today. Our premier font engine – Font Fusion - has built-in TV modes and anti-flicker filters to optimize characters on TV screens, whether interlaced or progressive scanning is used. btX2, our solution for Linux, also relies on Font Fusion to render text on Linux-based interactive TV systems.

The digital TV standard for font format
Bitstream technology has been adopted by standards' organizations worldwide, including ISO/IEC. These key organizations have adopted the Bitstream PFR (portable font resource) as their standard font format for digital television:

	ATSC (Advanced Television Systems Committee), which approved the DTV Application Software Environment, or DASE, standard. The DASE standard calls out the ISO standard for fonts
	DAVIC (Digital Audio Visual Council) sets multimedia standards for international broadcasting
	DVB (Digital Video Broadcasting), a Swiss-based industry organization representing one standard for digital TV, which has been adopted extensively in Europe
	DTG (Digital TV Group) coordinates standards for Digital TV broadcasting in the United Kingdom
	MHP (Multimedia Home Platform), which many European set-top box and digital TV manufacturers are using as their standard development platform
	ISO/IEC 16500-6:1999 (International Organization for Standardization / International Electrotechnical Commission), which together form the specialized system for worldwide standardization.
	OCAP (OpenCable Application Platform), which supports the DVB-MHP standard, including support for PFRs. The OpenCable initiative is managed by the Advanced Platforms and Services group at CableLabs.

Tiresias Screenfont for subtitling
Bitstream is the only authorized reseller of the Tiresias Screenfont, originally designed by a team led by Dr. John Gill, Chief Scientist for the Royal National Institute for the Blind. The RNIB developed the Tiresias Screenfont in response to a need for improving text for television subtitling. The DTG, DVB, and MHP have all adopted the Tiresias Screenfont as the standard font for their platforms.

Support for FCC-compliant closed captioning
Font Fusion supports font requirements mandated by the Federal Communications Commission (FCC), as specified by the Electronics Industries Alliance (EIA), including all the required and optional characters in the EIA-708-B specification.
