Video processor provides HD and beyond

IDT has announced the latest addition to its Hollywood Quality Video (HQV) family of video processors.
The new IDT HQV Vida processor enhances image detail and quality with four-field motion adaptive de-interlacing, multicadence tracking, expanded 12-bit colour processing and detail enhancement. The result transforms standard-definition sources to HD quality and makes HD look even more detailed. Moreover, the device also provides realtime clean-up of highly compressed video, reducing compression artefacts of block and mosquito noise from lower-quality sources.
The IDT VHD1900 incorporates two new IDT HQV technologies, Auto HQV and HQVStreamClean, which automatically enhance the incoming image and provide powerful clean-up of source video, making the picture crisp and clean. Auto HQV enables hands-free adjustment to optimise the image quality of content from different sources or content that varies in quality. Auto HQV analyses the video content to adaptively adjust image and noise processing parameters to optimise image quality and reduce artefacts.
With increased viewing of low-resolution and highly compressed Internet content on larger screen displays, compression artefacts and noise are highly visible and distracting to viewers. HQV StreamClean incorporates three noise reductions techniques: adaptive mosquito, block and temporal. These selectively reduce difficult-to-remove image artefacts. The Vida processor also contains resolution enhancement technology that generates pristine and detailed up-scaled images to make standard definition content look near-HD in quality and can even further enhance detail in HD content.
The VHD1900 also features 14-bit internal processing and 12-bit output for deep colour processing and 3D gamut conversion for xvYCC processing. These capabilities provide accurate conversion of regular and wide gamut content to the display’s native gamut. In addition, the VHD1900 features six-axis colour control, with independent adjustment of the hue, saturation and intensity of any colour.
All of this processing technology is fully integrated into a compact 128-pin TQFP. The new IDT HQV video processor features no external DRAM and, by integrating on-chip memory, can be incorporated into any video system. With its low power consumption and low latency, the Vida video processor is suitable for DVD and Blu-ray players, digital TVs, set-top boxes, personal video recorders (PVRs), audio video receivers (AVRs) and projectors, as well as mobile media device docks and media adapters.
