A PARALLEL VIDEO CONVERTER FOR DISPLAYING 4 3 IMAGES ON 16/9 HDTV RECEIVERS/

The 16/9 widescreen TV is popular in the recent market; however, its a spect ratio is not compatible with the conventional 4/3 SDTV program, In this paper, we propose a nonuniform conversion to efficiently displ ay 4/3 SDTV programs on a 16/9 high-definition television (HDTV) monit or, For real time HDTV receivers, a parallel video converter is also p roposed using nonuniform interpolation. To trade off complexity and pe rformance, we only use one field-memory and one line-buffer for motion adaptation to interpolate pixels, which can be finished by the parall el computation kernel in one clock cycle. In order to combine parallel computation, the memory-slice method is employed, which is efficientl y controlled by a state machine for nonuniform interpolation. With par allel conversion, a high-speed video converter can be achieved for adv anced HDTV receivers.
