New Toshiba DTV Solution Raises Frame Rates To Deliver Blur-Free High-Definition Video

Frame Rate Converter Includes On-board Picture Management and Scan Converter to Convert Conventional 60 Hz Frame Rate to 120 Hz for Higher Quality HD Images

SAN JOSE, Calif., — Toshiba America Electronic Components, Inc. (TAEC), a committed leader that collaborates with technology companies to create breakthrough designs, today announced the latest addition to its portfolio of digital TV (DTV) semiconductor solutions. The TC90240XBG device integrates a scan rate converter to upgrade standard 60 Hz signals to 120 Hz, greatly improving the blurry motion sometimes seen during fast-paced action scenes in high-definition content. LCD TV OEMs can easily integrate this new part into existing 60 Hz panel designs to quickly bring 120 Hz-capable LCD TVs to market.

“Traditionally, TVs have displayed images using a refresh rate of 60 Hz. However, in fast paced content like action scenes and sports, motion can often appear blurred,” said Shardul Kazi, vice president of the ASSP Business Unit at Toshiba America Electronic Components, Inc. This new product addresses the problem by converting conventional 60 Hz frame rates to 120 Hz, reducing blur when displaying 1080p high-definition content. Furthermore, the device uses a simple I2C interface so LCD TV manufacturers can easily accommodate the TC90240XBG in existing 60 Hz TV designs.”

The TC90240XBG uses low-voltage differential signaling (LVDS) connectivity to take the 60 Hz video signal from an LCD TV’s MPEG decoder, and using a combination of motion estimation and motion compensation, builds the additional frames needed to drive an LCD panel at a 120 Hz refresh rate.

Additional features of the TC90240XBG include:

• Interpolated frame generation using motion estimation and motion compensation
• De-judder of film material
• Picture management
  • Color management
  • RGB gamma correction
  • Frame rate control dither
  • Edge enhancement
• Integrated DDR-2 memory controller
• Input – LVDS 8- or 10-bit WXGA or 1080p signals in RGB, YCbCr or YPbPr format at 50/60 Hz Provides RGB to YCbCr function at input signal
• Output – LVDS 8- or 10-bit WXGA or 1080p signals in RGB, YCbCr or YPbPr format at 100/120 Hz
• YCbCr to RGB function at output signal
• I2C programming interface
• Internal PLL for clock generation
• PBGA-564 31mm x 31mm with 1 mm ball pitch
• Built-in memory controller supports DDR-2 at 533 MHz data rate
