Software Architecture of Light PVR Engine

摘要

This paper presents efficient software architecture for a PVR application which is capable of simultaneous recording and playback of HD quality MPEG-2 and AVC streams from DVB and ATSC networks. Presented approach provides scalable software architecture portable on low cost HW platforms with optional CA protection, thus providing end user with advanced features found in high-end devices such as: pauses, instant reply, skip, and fast forward/rewind.
