When it comes to video entertainment, consumers have a variety of options. Local cable or satellite providers offer users a choice of programs for hundreds of channels. In addition, movies and TV shows can be played on DVD and Blu-ray discs, from local video stores or online services such as Netflix.

With the proliferation of high-speed Internet access, most television networks can provide complete episodes of programming on their websites. Video entertainment is also broadcast online through formats such as AppleTV, Amazon Video on Demand or Hulu, while websites such as YouTube can access video from a variety of sources. These online broadcasts offer consumers more viewing options. In addition, as CE devices quickly become Internet-ready, you can easily display them on HDTV.
This is where the problem lies. Consumers want to see a clear picture on their new big-screen flat-panel HDTV, no matter what the source. If the source is a Blu-ray Disc or a high-rate HDTV broadcast, the image on a large, flat-screen HDTV will be very clear. However, if the source comes from standard definition or low bit rate broadcasts, or real-time video streams from the Internet, the image will have a lot of distortion and it will be difficult to reach the user's expectations.
Online video broadcasts are limited by the bandwidth offered to the end consumer. Since most consumers have bandwidth limitations that are far below the requirements for full quality video, online providers highly compress video files for delivery and ultimately broadcast. These highly compressed video streams will include significant mosaic and mosquito noise distortion. This will be very noticeable when the image is displayed on a large screen.
Noise distortions originating from poor cable box output and Internet video are often rendered in the image through a series of transcoding, scaling and pre-processing, making it difficult to find and eliminate. In addition, when trying to clean up these images, traditional video processors tend to remove a lot of detail from the source image.
The latest products in the IDTHQV video processing product line are designed to solve these problems.
The IDTHQVVida processor (VHD1900) uses powerful compression and noise reduction technology to remove mosaic and mosquito noise from low quality sources. In addition, the Vida chip uses HQV resolution enhancement technology, combined with an adaptive detail enhancement engine and high-quality up-conversion to achieve near-HD quality SD video, and even further enhance HD material details. To preserve all the nuances, the details and intent of the original source, the Vida processor is ideal for Blu-ray players, audio/video receivers (AVRs), personal video recorders (PVRs), digital TVs, set-top boxes and digital media adapters.
The new Vida processor includes HQVStreamCleanTM, which integrates adaptive mosquito noise reduction, mosaic noise reduction and time noise reduction to eliminate image distortion that is difficult to remove from low quality, preprocessed video sources. Unlike traditional video processors, the Vida processor also features adaptive filtering to essentially preserve image detail.
The VHD1900 chip also features automatic HQVTM technology that automatically analyzes incoming video to determine its quality and selects the appropriate audio processor settings for the source material. This will help devices using the Vida processor automatically adapt to changing source quality, providing the best possible display without the user having to adjust any settings frequently.
"The pattern of consumer video is changing. More content is available on the Internet. If you download video from YouTube and watch it on a large screen display, compression," said JiPark, vice president and general manager of IDT's video and display business unit. Distortion will be very noticeable. Importantly, video processors can clean up this and conventional content. HQV is considered the definitive standard for today's video processing. Moreover, with Vida devices, IDTHQV pushes video processing to a better level of processing."
The powerful Vida processor also features the latest IDTHQV video processing features, including high-quality resolution enhancement, four-motion adaptive deinterlacing, multi-field support and adaptive contrast enhancement, all designed to enhance the end user's video experience. Consolidate IDTHQV as the industry standard video processing technology. IDTHQV's latest products also feature 14-bit internal processing and 12-bit color depth processing output and xvYCC processing 3D color gamut conversion. These features provide accurate conversion of regular and wide color gamut content to the display's native color gamut. In addition, the VHD1900 features 6-axis color sharpness that independently adjusts the hue, saturation, and brightness of any color.
In addition, the Vida chip implements all of the features in the industry's smallest video processor, helping designers save board space, increase functionality and design flexibility, and ultimately speed time to market.
Summary: IDTHQV is recognized as the industry's leading video processing solution, and the new Vida processor sets a higher standard. All HQV algorithms have been enhanced to meet a variety of content needs and to 12 digits for the highest quality results. xvYCC color processing adds a full 6-axis color control engine and resolution enhancement engine that pushes SD images closer to HD quality and improves the details of HD content. In addition, the new HQVStreamClean technology uses powerful video processing technology to clean high-compression, low-quality video broadcasts at any time. The automatic HQV function also provides hands-free adjustment to optimize image quality from different sources or content of different quality.
