CyTV is a streaming solution for elgato's EyeTV family of TV tuners. It allows you to watch TV and recorded programs over a local network (wired or wireless) or the internet. You can pause and resume live TV on the client ("timeshift"), and you can also change channels remotely.

The CyTV Server requires a Mac with an EyeTV unit. On the client(s), you can use the VideoLAN Client (VLC) media player to play the stream, so you can watch on any platform supported by VLC (and there are many!). The distribution also contains a special client application for Macs that gives you more control (like watching previous recordings, skipping back and forth, etc.).

Requirements:
OS X 10.2.5 - 10.5
EyeTV unit.
VLC media player. The CyTV disk image also contains a special CyTV client for Mac OS X (but you still need VLC in addition to it!).
Supported tuner models can be found in the compatibility chart.
