In a previous post The Sony PS3 Can... I mentioned streaming content from your computer to your PS3. I would like to expand a little more on that. You don't have to be a tech guru to own a computer or a PS3, and the software to connect the two is very simple. The only requirement is that the PC and PS3 are connected to the internet in the same house.
The first step would be to have some form of media on your computer that you would like to share. This could be pictures, music or videos. Personally I have taken about 200 of my favorite DVDs and ripped them on to the computer. I like to call this "digitizing" or creating digital backups. So I have 200 DVD quality movies on my PC ready to be watched.
The second step is to install a program called Java PS3 Media Server. Note that this software is designed for the PS3 but will work with the Xbox 360and certain network ready televisions. Once the program is installed, you just tell the program which folders you keep your media in and your good to go. Now you can watch all the movies on your computer, on your big screen TV without the need to find or change DVDs.
Something else I like to do is watch movies in bed. Well I don't know about you but watching movies in bed at 2AM is going to piss someone off. So I like to watch them on my PSP (Playstation Portable) with headphones on. The greatest thing about the PSP is that it has a feature called "Remote Play" which allows it to connect to the PS3 (even if it's turned off) and access any of its media. So by having all of the movies streaming to the PS3 from the PC I can watch all of the movies on my PSP, through the PS3, that are stored on the PC. I can lay in bed and watch movies without having to copy any files to the PSP or insert any DVDs. The PSP can access the PS3 through the internet too, so you could be at a friends house watching a movie through your PS3 at home... it's brilliant!
If this is something that you would like to get setup in your home let me know how I can help.
