Abstract
A media playback device capable of displaying multiple streams simultaneously and with expanded picture-in-picture capabilities is provided. The placement, size, aspect ratio, cropping, scale, transparency, tint, contrast, and cropping of the media can be set or adjusted arbitrarily. Furthermore, the audio may be mixed between separate tracks accompanying the video streams and may also be set or adjusted arbitrarily. Each variable can be dynamically changed during playback through either automated or user-initiated means. A system and method are provided for simultaneously displaying a first video stream and at least a second video stream on a display comprising the steps of feeding the video streams into a video player; providing control of the display of the video streams; displaying a first video stream substantially across the display; and displaying the other video streams in a secondary display.
