Multimedia applications enabled by 4C technologies are creating vast new
market opportunities for content providers, service providers, application
developers and device manufacturers. 4C Entity has worked closely with the
digital entertainment distribution ecosystem to provide the best content
protection. Its CPRM/CPPM specification was designed to meet the robustness and
renewability requirements of content owners while balancing the implementation
needs of both the consumer electronics and PC industries.
Compelling new business models and use cases are being enabled by 4C
technologies. Using CPRM, content and service providers could roll out exciting
new services that would enable consumers to playback content downloaded from a
music distribution site to cell phones, in-car systems and other portable
digital devices. In the future, users will be able to easily move music
libraries between a variety of SD-enabled devices, including cell phones,
portable audio players, PCs, car stereos and other mobile devices.
CPRM also could enable services for recording digital terrestrial TV
broadcasts. Mobile TV programming is already delivered in Japan through
"One-seg TV," a new form of digital terrestrial broadcast (ISDB-T). With
new digital content distribution and broadcasting services, carriers and cell
phone operators could provide security for content downloaded to their specific
network mobile phones. The content could be bound to the cell phone devices and
thus prevents unauthorized copying to other devices or computers.
CPRM also can be used for retail store media kiosks. Consumers can select
titles from a library of thousands of movies and television shows, insert their
SD card, swipe their credit card or membership card, and the selected title is
written to their SD card. The business models for this use could include video
content subscription, rental, and purchase models.
