Many TV’s are now coming out with USB port build in. You are wondering what it is for, right? Well, the answer to that question is not entirely simple. Different manufacturers offer different features that can be used through the USB port. For the most accurate answer you will have to go to your manufacturer’s website and look up your TV’s model; and skim through the specifications and details.
You will not be able to just plug in any device (iPod, MP3 or MP4 player) that has a USB output on it to your TV. You can plug in a flash drive, card reader, and maybe even a hard drive that has external power source.
The most basic features your USB port will most likely offer is picture viewing capabilities. You will be able to see your JEPG pictures and some even offer RAW image viewing capabilities. The next common feature is audio playback of MP3 files. Some TV’s support WAV files but it is rare feature. Video playback feature is becoming increasingly popular on build in USB ports. There are limitations on what files you can play; again check the manufacturer’s description, but most common video file types are AVI, MPEG2 and MPEG4. However, some USB ports are there for service only and will not offer you any playback features.
