Three approaches of an MPEG-2 compatible coding technique are presented for stereoscopic sequences. The first method utilizes the spatial scalability structure and the second employs the temporal scalability syntax. The scalability extensions of the video coding standard make the processing easier to accommodate the transmission of a stereoscopic video stream. The left and right channels reguired for a stereo sequence are correspondingly supported in the base and enhancement layers of the scalability structure. The enhancement layer selects the best prediction combination of the spatial and temporal information.
