A Second Generation Architecture for Linux DVB Networking

IP/DVB operating system support for the second generation DVB physical carriers is still limited to the so called broadcast profile that supports only CCM mode and encapsulation of IP packets into transport stream packets. Both MPE and ULE are currently used encapsulations therefore. The interactive profile, in contrast, provides a generic stream interface that allows for efficient use also in VCM and ACM mode and provides with GSE a new encapsulation. This paper presents a novel architecture for Linux kernel based operating systems to support second generation DVB carriers.
