Client-Server server

#This is a basic guide and it supposes you have advanced knowledges. All are common net configurations and the programs are free and included in all linux distributions. too works as a client-server for local networks, that is video on demand like some IPTV providers offer for one week or so of the broadcast channels's past programs although this service for paid TV subscribers lacks some promised features like it only stores a few channels and only local productions's programs cause legal questions. With your home server distributes videos of television channels at your choice, recorded continuously, the time margin is until you want, with linux machines, naturally you need ultra durable and low power consumption components, and a UPS, there are many cheap computers that consume less than a lamp which may be more than enough.

You can configure your sever for unattended operation, after a reboot of the system will continue to work with minimum data lost. For console only servers, If TV-card initialization is needed optionally it launches ttv instead of xawtv.

To configure in your LAN you can try SAMBA/CIFS or any other network file access like NFS or iSCSI (iSCSI needs a special solution for concurrent access), you have to configure for record the video buffers in a server's share directory and then clients access these videos as they were in their hard disk... and then too others if you install more capture cards or if you have one capture card with multiple analog capture devices, in this case be careful about issues like antenna signal loss, poor framerate with cheap multidevice cards, you might need additional sound capture lines, and the max power of your processor. has no digital TV support, If you receibe digital channels or your video card has no tuner then you need stable external decoders connected through SCART (it does not support high definition), although this configuration requires more space and consumes a little more, image quality is good and has some advantages like easy channel change or programmable via decoder and, it may be, is less copyright restrictive.

SAMBA/CIFS configuration should be: server with access to a local dir without mount.cifs it and client mounts.cifs this share dir with -o nounix,directio to fix symbolic links and no caching (file refresh issues if caching is active but it works well too for at least one buffer delay; nounix if timeshift buffers's full path doesn't match on both clients and server). With the suggested options you get the exactly same functionality and speed as in standalone mode, server recording video while one client watching it works fine and client can watch the TV channel near live without file locking issues.

Don't worry about security, server side is simple, at least as secure as your linux server, without X-Windows for extra performance and stability, really the most important is net stuff up-to-date and iptables allows only ro clients inside the local network. SAMBA/CIFS is well known, recommended and tested option.
