Home Theatre (as in TV?!?)
I thought you were refering to an audio system.
Indian and US TV broadcast standards are substantially different. India uses the European PAL (B) system. The USA uses NTSC (M) A US TV will not be capable of viewing Indian broadcast channels without a converter.
However, you *may* be OK if you hook it up to an RGB feed from a digital satellite set top box.
(you will also need cables to convert from SCART (european standard 20 pin A/V connector) to whatever is on your US TV)
Also, any DVD player purchased in the USA will only play Region 1 (North American) DVDs unless it's specifically multi-region. You may, however be able to hook up an Indian DVD using RGB or digital connection. Connecting it to the speaker system will be absolutely no problem (although the connectors in Europe and the USA are slightly different!)
In the USA speaker connections are normally "banana plugs" these are not used on european equipment as they happen to perfectly fit European 230V socket outlets! Also, partially inserted banana connectors can expose users to relatively high voltages in high power speaker systems.
US style banana plug
European version. (shrowded and too wide to fit into any european electrical outlet)
You may need to fit banana connectors if your speakers / equipment has bare cables. Some equipent uses screw on binding connectors for speakers or, on smaller speakers, push in connectors that accept the bare cable ends.
Older CRT (traditional tube-based) used the line frequency to time the refresh rate on the screen. i.e. European PAL tvs operated at 50hz and US NTSC TVs operated at 60Hz.
I would expect that a home theatre / home cinema TV would be a little more advanced than that and will more than likely not worry too much about the 50hz frequency.
I have no idea what the scenario is with plasma or LCD screens.
Best of luck with your system! I hope it works!
Make sure you get a good step-down transformer and use surge protection!
Also, be aware that some transfomers wound for 60hz supplies can produce more heat when operated at 50hz... It's usually not an issue, but worth keeping in mind with something like a television! i.e. do not leave it operating on its own without supervision and don't leave it plugged in on standby overnight!
