Yes, that's very likely.

'ls -l /dev/video*' will tell you. If it's a chardev, the permission
bits will start with c rather than b (as is the case for block devices).

Have you looked at vlc? It supports live streaming of whatever you're
playing over the network. I use it to stream DVD's from my laptop (with
12" screen) to my brother's desktop (with 17" screen, but without
DVD-ROM). Works like a charm.

Don't know whether it also supports /dev/video* devices; but if it does,
that's what you want ;-)
