Answer:
There are a number of solutions for a full home control project. Several manufacturers make control equipment that can be configured to suit the requirements of homes, offices, theaters and more. Manufacturers of equipment are Crestron, AMX, RTI and many others.
The choice of control systems is less important than other considerations. The first decision is what needs to be controlled. It might be the television and sound equipment or perhaps it will include lighting, heating, security and so on.
Next, a whole house control system will need a significant amount of wiring. Although wireless networking has made its way into home control, accept that you will be adding wiring to make it work.
While your existing equipment can probably be controlled, there will be more equipment that will have to be purchased
Finally, a home control system is much more complex than a programmable television control. Configuring the system will involve programming and tha will involve hiring a programmer to do the job. Most control system manufacturers only distribute programming tools to registered and certified programmers so there is rarely a do it yourself option. The operation of the system is dependent on the work of the programmer. Before taking on a programmer, know what you want to achieve and don't be afraid to discuss the operation in detail with a programmer. Don't ever accept a programmer telling you that he knows best. Listen to his advice of course but it's your system so make sure you get the system that you want.
Oh, one last tip. Make sure you have a clear credit card when you start. It won't be cheap.
