Silicon Image's patented VRS® ClearView™ technology scales and cleans video from any source, optimizing it for HD displays.
The UltraGig 6400 is a single-chip solution for 60 GHz wireless connectivity in smartphones, tablets, and other mobile devices
Silicon Image re-launches SiBEAM, Inc. subsidiary to drive market development of millimeter-wave products, technologies and solutions.
Silicon Image's high-quality cineramIC™ video processing IP cores are designed for integration with digital image processing blocks such as video encoders or decoders for digital video system-on-chip (SoC) designs that deliver optimum image quality. Chip designers will be able to embed Silicon Image's industry-leading video processing technologies into a wide range of consumer electronics devices including DTVs, Blu-ray players, digital media adapters, and set-top boxes, as well as mobile phones, tablets, and laptops, where advanced image enhancement technologies may not have been implemented previously.
Real-time High-Quality Video Processing Technology
Silicon Image's patented adaptive scaler is optimized for standard-definition as well as for high-definition and ultra high-definition resolutions up to 4Kx2K. The scaler supports scaling in both up and down directions.
Video scaling is required to adjust the original resolution of a video source to the size of a display or to allow the viewer to zoom into an image. The typical SD video resolution provided by a DVD player or set-top box is 480i (NTSC) or 576i (PAL). After deinterlacing the video to a progressive format (480p/576p), this resolution has to be upscaled to the resolution of the DTV (720p or 1080p) or computer display. Scaling is also required to adapt 720p video resolution to a 1080p display and vice versa. In a video SoC for a Blu-ray, DVD player or set-top box the adaptive scaler IP core is placed in the digital video processing chain behind a video decoder (such as Silicon Image's H.264/MPEG-2/VC-1 cineramIC video decoder IP core) or as part of a video output unit which sends the video content to the display. In a DTV SoC, the adaptive scaler IP core has the task to convert any incoming video and still image to the native display resolution.
This latest scaling engine produces optimal picture quality regardless of image content. The vertical and horizontal scaling engine preserves detail in the original image and it includes features such as chroma up-sampling error correction and optional sharpening capability. The keystone correction feature avoids trapezoid-like distortion of a non-centered projector. The sophisticated second-generation panorama (non-linear horizontal) mode offers a smoother conversion of a 4:3 aspect ratio input image to fill the standard 16:9 widescreen aspect ratio of today's DTVs. Building on previous successful scaling technologies, the adaptive scaler preserves image detail in video content while suppressing ringing artifacts in graphics content.
