National Semiconductor Introduces First Dual-Channel Video Format Converter for High-Definition Digital TVs and Home Theater Products

New Video Format Converter Drives HDTV Screens with up to 1080p Resolution, While Unique TwinD Architecture Provides Secondary Output for Time-shifting or Recording

Apr 18, 2005

NATIONAL ASSOCIATION OF BROADCASTERS CONVENTION, LAS VEGAS, Nevada – April 18, 2005 – National Semiconductor Corporation (NYSE:NSM) today introduced a dual-channel video format converter for high-definition digital television (HDTV) screens up to 1080p (line progressive) resolution, including LCD (liquid-crystal display), plasma and rear-projection television.  Applications include digital televisions, audio video receivers, video processing boxes, digital recorders, up-conversion digital players, high-definition recorders that utilize Blu-Ray and high-definition format discs, personal video recorders and set-top boxes.

"The simultaneous high-definition (1080p) and standard-definition output streams of the TwinD architecture make this device a very user-friendly and cost-effective way to design high-definition consumer devices with highest quality video processing functionality," said Alan Clark, Principal Engineer for Classé Audio Inc., a Québec designer of components for high-end audio and home theater systems.  "Unlike other solutions that provide 1080p outputs through down- and up-scaling of 1080i signals, National's solution is capable of 3D deinterlacing of 1080i to 1080p formats, allowing our CDP-300 DVD player to provide a state-of-the-art image quality for high-resolution, large-panel displays and projection systems."

The AVC2510 dual-channel adaptive video converter accepts PC graphics, as well as standard- and high-definition digital video inputs.  It then processes them to produce high-quality output in any desired standard video format up to 1920 x 1080p resolution.  The converter contains one full-quality 3-D video pipeline and one secondary pipeline that perform scaling to support picture-in-picture and thumbnail functions.  Extensive noise-reduction functions, contrast enhancement and color re-mapping enable optimum image rendering.  The TwinD architecture provides simultaneous output of a primary, high- or standard-definition data stream and a secondary, standard-definition version of the same data stream, allowing easy implementation of a monitoring or time-shifting function.

"Today’s consumers have access to a wide range of video formats, from standard-definition content to high-definition programming," said Dr. Nikhil Balram, chief technology officer for National’s Displays Group.  “The challenge is to format this content and render an optimum image on a wide range of display devices including the new generation of 1080p digital televisions, while providing the ability to time-shift this content.  The AVC2510, the first in a family of adaptive video converters with the unique TwinD architecture from National, was designed to meet this need.”

National Semiconductor and Videon Central, a leading supplier of video solutions are offering applications based on National’s AVC2510 video format converter.  Videon’s universal video converter board will enable the rapid placement of National’s technology into a wide range of video applications, including LCD TVs, audio video receivers, video processing boxes and DVD players.
“National’s AVC2510 provides Videon Central with best-in-class video converter technology,” said Todd Erdley, president and chief executive officer for Videon Central.  “Videon is the first to provide original equipment manufacturer’s in the high-end home theater and consumer electronics markets with a universal video converter board based on National’s AVC2510.  National’s technology, coupled with its outstanding support team, enabled an unparalleled design experience.”

Pricing and Availability
The AVC2510 is packaged in a 240-pin PQFP.  National offers all its packages with a lead-free option.  Samples of the AVC2510 are available now by contacting a National Semiconductor sales or distribution representative.  In 1,000-unit quantities, the AVC2510 is $49 each.  A reference design that includes National’s ADCS9888 video analog front end and LM1085 low-drop-out positive regulators is available by contacting Videon Central via email at
