Every time I get visitors they do get blown away by the Media setup I have at home. By Media I mean the way Photos, Movies, Home Videos and Music (as well as TV and Radio) are easily available on my TV screen and controlled by remote control. Now this is neither a revelation nor an alien technology people! This is simply a PC that is camouflaged as an Audio-Video device such as a DVD or an amplifier very similar to the below photo.

As you can see this looks as simple Amplifier device that can be found in an home. Nevertheless this is a simple desktop PC that has the regular components such as Hard Disk, CPU, Memory, etc.
Now is is becoming the trend for every Home Entertainment and if you don't have one yet then I am sure you will end up having one very soon. Especially that the cost of such a device can be as low as 1000$. Before diving into the details of such a device (no worries, it will not be technical, you can continue reading) allow me to provide some basic definitions for the non-techies reading this blog:
- MCE: Media Center
- HTPC: Home Theatre PC
- HDMI: This is a type of cable that links the PC to the Amplifier and TV. Through this cable flows Audio and Video
Let us start with the Case.
As I said before, an HTPC is a regular desktop like the one you use at work (unless you use a laptop). From the inside it looks like that:

Nothing to it really, the few basic components found in any Desktop PC including an HDMI connectivity that is standard nowadays. The only addition of an HTPC is that it comes with an Infrared sensor and a remote control that allows you to navigate through the interface.
Next is the software that you can use and the capabilities.
For the software you can use any version of Windows (XP, Vista or Windows 7) that have the Media Center built-in. I would recommend that you use the ULTIMATE flavor of Vista as a sure bet to contain Media Center.
Obviously the software will scan you hard disc for photos, Videos (home videos or movies/series) and for music. These are known as your 'Media'. Below are some snapshots of how your Media will look like.

Obviously this PC can connect to the internet and download relevant information for you such as Movie details and posters, Music cover art and lyrics, it can display weather information and provide nice visualization for you photos.
Lots of extra features are found as built-in as well. To name a few you have streaming to other computers at home, creation of playlists, podcasts and access to plenty of features online (taking into consideration you have the required internet access and speed). Now the major feature that makes this product a MUST is the Radio and TV functionality that it provides.
For the radio, you can have all your favorite radio stations accessible on screen to navigate through. As for the TV the HTPC offers a full PVR functionality. What is a PVR? a PVR is the capability of displaying your TV station on your screen through the HTPC. This would allow you to Pause Live TV, rewind, skip ads,record your favorite programs/shows and of course schedule recording of multiple programs simultaneously. (If you are impressed by this last feature then you are a couch potato. You should avoid getting an HTPC and go out more. Get a Life!).
I am not going to dwell longer on this but I highly suggest you google 'Media Center PC' and spend some time reading through the results. You will be impressed I guarantee it.
