PSP is a handheld game console released and currently manufactured by Sony Computer Entertainment. Its development was first announced during E3 2003, and it was officially unveiled on May 11, 2004 at a Sony press conference before E3 2004. The system was released in Japan on December 12, 2004, the United States and Canada on March 24, 2005 and in Europe and Australia on September 1, 2005. It is considered the first handheld video game system to use an optical disc format (Universal Media Disc).
The PlayStation Portable is also able to playback movies on a UMD Universal Media Disk format. PlayStation Portable’s audio player supports a number of audio codes, including ATRAC, AAC, MP3, and WMA, and has the option to be played with or without a set of five visualizations. The image viewer will display several common image formats including JPEG, Bitmap, and PNG. However, image viewing is limited by the file size and resolution of the image and any image exceeding a file size or resolution cannot be displayed. This is usually the case with attempting to show DSLR images on a PlayStation Portable.
MPEG-4 and AVC video formats are also compatible with PlayStation Portable. With reasonable video and audio bit-rate settings (a resolution of 320×240, a video bit rate of 500 Kb per second, and an audio sampling rate of 22050 Hz) a 22-minute video file is roughly 55 MB, enough to fit on a Memory Stick Duo as small as a 64 MB. At the same rate, a hundred-minute feature film can fit on a 256 MB Memory Stick. As of firmware update version 3.30, H.264/MPEG-4 AVC Main Profile video files of the following sizes can be played: 720×480, 352×480, and 480×272. Many video files, both free-to-distribute and copyrighted, have been encoded for the PlayStation Portable and are available on the Internet. Game and movie trailers are increasingly available, even from studios’ official websites.
With these superior features, you can even store your favorite DVD’s and music in your PSP. And if you’re the customizing type, you can also change the thumbnails of these movie files. Here’s a quick guide on how to get your own custom thumbnails for media files on your PSP using Photoshop:
Create your thumbnail using Photoshop. Try to create at Width: 160px x Height: 120px, Resolution: 72 pixel/inch, since this is the size we will the saving the jpg as.
Once you’re done with your image, in Photoshop, go to File > Save for Web
Then in the Save For Web box, change the settings in red and then click Save.
Finally, we will need to rename the .jpg file we just created to be the same file name as the movie but with the .THM extension.
Lastly, transfer the files to your psp and make sure that the media file and the .THM file goes together.
