Video and Imaging Solutions

Displays and Multimedia

LOGIC’s off-the-shelf video product solutions are designed to handle the range of frame buffering requirements found in SD and HD displays. The image processing block of a display typically includes functions such as scan rate converter, frame rate converter, color decoder, motion detection, scalar, and de-interlacing. Each processing stage requires the handling and manipulation of video frames.

High Definition without High Overhead

Flat panel displays (LCDs, plasma display panels, plasma low-profile, and liquid crystal on silicon) and video projectors receive, decode, synchronize, and display digital video streams from a variety of sources.

Resolution, brightness, contrast and clarity impact the reality of the experience. It is critical for TVs to support multiple ATSC DTV formats, NTSC and PAL decoding, composite and S-Video inputs and 2D adaptive filtering. As HDTV adoption progresses, support of HD 1080i and 1080p formats with 3D adaptive filtering will be standard.

The heart of the LCD HDTV is its image processing and timing control block (shown in Figure 1).
