1. A method for playback of a compressed image stream, of a stereoscopic image stream having a first format into at least one display input signal compatible with a stereoscopic display device, said compressed image stream comprising a plurality of merged image frames, each frame consisting of a merged image comprising a compressed left image and a compressed right image, the method comprising:
defining a plurality of selectable display modes according to a desired display device, wherein said display modes include a conventional 2D mode and one or more stereoscopic 3D modes;
selecting one of said display modes;
placing at least two adjacent pixels into an input buffer and interpolating an intermediate pixel reconstructing an image stream, wherein when said 2D mode is selected, said reconstructed image stream is from one of said left image and said right image, and wherein when said display mode selected is stereoscopic, said reconstructed image stream is a stereoscopic image stream from said left and right image in said merged image frames;
generating from said reconstructed image stream at least one said display input signal in said selected display mode so as to be compatible with an input of said desired display device;
providing said at least one display input signal to a display device;
viewing on said display device said stereoscopic image stream in said 2D mode when said 2D mode is selected, and viewing on said display device said stereoscopic image stream in a stereoscopic 3D mode when said display mode is a stereoscopic 3D mode.
