ASSP improves HD image, video quality

NEC Electronics has developed a new the PD9280GM super-resolution ASSP, which can reduce blurring that occurs when low-resolution images and video are expanded and displayed in 1920 x 1080-pixel high-definition (HD) monitors.

The ASSP achieves crisp images in HD TV broadcasts by boosting 720 x 480-pixel standard definition (SD) image data. It is also capable of supporting one billion colors (30bit color depths), which enhances color vividness and accuracy of display. The rapid development of high-performance digital audio/visual devices, such as mobile phones and digital TVs, has left consumers with the challenge of how to view low-resolution images on their new high-definition electronic products. For example, 1920 x 1080-pixel HDTVs have 6x the resolution compared to the 720 x 480-pixel SD image data, which results in blurred images.

Although many image-enhancement technologies have been developed to process low-resolution image data into full HD images, designers, using traditional solutions, need large-capacity external memory devices and high-performance compute engines, and face other challenges to achieve real-time processing for vivid moving images.

The PD9280GM super-resolution ASSP enhances SD video and image data for crisp display in full HD. With increased operating frequency of 150MHz, compared to the previous 108MHz, this improved operating frequency supports advanced processing of image data and boosts images with higher resolution even on full HD TV broadcasts. The super-resolution technology is also available as an intellectual property core.

The ASSP also extends its color quality from 24bit color supporting 8bit-per-component of RGB color, to 30bit color. While 24bit color is only capable of displaying 15 million colors, 30bit color, aka Deep Color, can display one billion possible colors with smooth color gradation.

In addition, conventional image-resolution technologies used a multiframe technique to process image data, which required large-capacity external memory making it expensive and difficult to create hardware capable of real-time processing. NEC's super-resolution technology enables high-resolution processing with just one frame of image data. Reducing the processing load eliminates the need for expensive, external, high-capacity memory.

Samples of the PD9280GM super-resolution ASSP are available now at $20 each. Mass production is scheduled to begin in July 2009, starting from 100,000 units per month, expecting to reach approximately 1,000,000 units by 2010. (Pricing and availability are subject to change without notice.)
