Abstract:
1. A system comprising: a video player; a memory operably associated with the video player in which DVD-Video data is encoded, wherein the DVD-Video data, when played by the video player, causes the video player to simulate output of multiple simultaneous separately selectable video streams using a single video display layer, a single picture-mask layer, and a single highlight layer defined by the DVD-Video data, by (i) decoding the display layer to provide a first video stream including video data for displaying a representation of a video stream image and a representation of a sub-stream image on a display device, each representation simulating a respective one of separate moving image video streams for simultaneous display in distinct screen areas of the display device, and by (ii) selectively masking and unmasking at least the representation of the sub-stream image as defined by the picture mask layer, in response to input received by the video player from a user input device, while revealing the representation of the video stream image.
