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.
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).
