A flexible display module for DVD and set-top box applications

This paper presents a flexible, multi-mode display module for DVD and set-top box (STB) applications. The display module features: (1) vertical/horizontal post processing for chroma upsampling and rate conversions; (2) aspect ratio conversion for displaying 16:9 or 4:3 decoded pictures on either 16:9 or 4:3 devices; (3) user programmable, window based display with half or double window resizing; (4) sub-picture mixing and OSD overlay. All these functions are supported for both interlaced and progressive picture formats for PAL as well as NTSC systems.
