Abstract

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