Drivers for the Adoption of Multi-service Networks Digitalization of entertainment and other consumer content makes it possible to use available transmission media resources more efficiently, to use universal storage solutions for the content while providing end user quality experience equal to or better than analogue media.

Content delivery channels of this type exist or are becoming available in the form of digital telephone networks, digital mobile network systems and digital television. . | 1 Drivers for the Adoption of Multi-service Networks Digitalization of entertainment and other consumer content makes it possible to use available transmission media resources more efficiently to use universal storage solutions for the content while providing end user quality experience equal to or better than analogue media.
