METHOD AND SYSTEM FOR MULTIPLE PROGRESSIVE 3D VIDEO FORMAT CONVERSION
A 3-dimensional (3D) video receiver may be operable to scale a decompressed 3D video frame having a first 3D video progressive format to generate a 3D video frame having a second 3D video progressive format, where the second 3D video progressive format comprises a high-definition multimedia interface (HDMI) format. When operating in an electronic program guide mode or a graphics over video mode, the 3D video frame having the second 3D video progressive format may be blended with graphics. The 3D video frame having the second 3D video progressive format may be converted to generate a 3D video frame having a 3D video interlaced format by performing a pulldown. The 3D video frame having the second 3D video progressive format at a 50 Hz frame rate may be frame-rate upconverted to generate a 3D video frame having a third 3D video progressive format at a 60 Hz frame rate.
