Bitstream PFRs: The
Standard Font Format for Digital TV
The Bitstream patented portable font resource (PFR) was developed
to create portable fonts for the Internet. The PFR is a compact, resolution
and platform independent format, representing scalable outline fonts.
Independent organizations responsible for setting digital TV standards
have adopted the PFR as the chosen font format for digital television,
including:
 |
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. |
Many of our OEM partners are using Font
Fusion and our PFR technology to build cable, satellite, and
set-top box systems for digital television. |
