Transcoding is important to have because there are a lot of music, photo and video formats, but most DLNA devices only support a small handful of those.
For example, new digital photo cameras can take pictures in RAW format, allowing you to edit them later, but how would you view them in RAW format on your TV or other DLNA device? This is where transcoding will help you, because KooRaRoo Media will automatically, on-the-fly, convert these to a picture format compatible with your device.
You can have your music collection stored as high-quality FLAC files, but most DLNA devices do not support FLAC directly. Again - KooRaRoo will save the day and convert your music files with the highest possible quality to a format supported by your device.
The world of video formats is the most complex, because video files are basically containers that can have many different streams (channels) inside and each of those streams could be a video stream, an audio stream or a subtitle stream. Even the most popular formats, such as AVI (or DivX) and MPEG can be encoded in a way that makes them incompatible with hardware decoders (hardware decoders are what's built-in your DLNA devices). New camcorder models will let you take beautiful, high-definition home videos, but these videos may not play on your device as well, even if they are the same brand. You also may find some videos on the Web or elsewhere that are encoded in less common formats that are not supported either.
As you can see, there are many possibilities for things to go wrong in terms of compatibility between your files and your device, but the good news is that you don't have to worry about this - KooRaRoo Media will take care of it all for you behind the scenes.
