Mumudvb is a program that redistributes streams from DVB on a network using multicast or HTTP unicast. Its main feature is to multicast a whole DVB transponder by assigning each channel a different multicast Group. It can operate Conditional Access Modules (CAM), and therefore works with encrypted streams. It has very low CPU and memory usage.
PASAP runs in the background, checking whether a stream exists, and, if it does, plays it. It was originally written to play back audio provided by MPD in remotely networked locations, but it also allows consumer-grade HD decoders (WDTV) to automatically play back audio/video streams from an HTTP address.
