Help on TV Middleware

Hi,

I have three PCI Cards on a Linux system.
1. for DVB-S
2. for DVB-C
3. for S-Video output.

I need to implement a Hotel hospitality system for hotel rooms.

As an initial assignment,

For example if the guest send the request (using a IR or suppose keyboard input at the moment) for watching TV (DVB-S), The Linux system should get the input and check whether guest ask for DOB, or DVB-S , or any other. Then it should switch the DVB-S input to S-Video output.

Here the Linux System works like a Set-Top-Box. All pci cards detected and also I installed Linux-dvb-api.

Do I need to write a code or program to access the input from the guest? If it is so do I need to use Linux-dvb-api with C. or any Java API is there for that to do. Can I use any existing open system with combination? Can anybody help me to initiate to start this project?

If I am streaming the decoded mpeg and display to plasma which tool is better to customized for my request (like MythTV or VLC or any)

I got little knowledge on Linux-dvb-api, C, MythTV, and also VCL. And also I got little idea on Java TV API. And I ready to study deep these all if needed for my hospitality project. I am also having good knowledge in Java and ready to study anything for this project.

Only I need a help which to study and how I can (using which tools) implement this.


Thanks
