According to the company, the new solution allows simultaneous display of images on both liquid crystal display (LCD) screens and external video devices such as televisions and video graphics array (VGA) projectors. It features low power requirements and does not require the host processor intervention beyond setup and configuration.
Jing Ma, director of partnerships and strategic alliances at QuickLogic said: This new simultaneous display solution enables developers to implement a wide range of exciting handheld capabilities such as plugging a PDA into a conference room television to give a presentation, playing a mobile-phone video game on a TV, or even watching a movie stored on a portable media player on any TV.
QuickLogic said that the device integrates its ultra-low power programmable fabric technology with Chrontel’s CH7013 TV encoder and mobile synchronous dynamic random access memory (SDRAM) frame buffer to implement the memory interfaces, red green blue (RGB) interfaces, X-Y swap conversion logic and active power management. It added that it provides all rate conversions and voltage level shifting required for getting input data from the LCD display controller to drive the TV encoder.
David Tsai, director of marketing at Chrontel said: We have successfully developed an approach that enables portrait-oriented images and video from mobile handsets, personal digital assistants (PDAs), and portable media players (PMPs) to display correctly on conventional NTSC and PAL displays. QuickLogic’s CSSP handles all the timing related to the various display rates and scan direction conversion while the CH7013 processes and tunes the video stream to produce excellent TV-out quality.
In May 2007, Fujitsu Microelectronics launched the SmartMPEG-C, which is an advanced digital television decoder with features, including support for personal video recorder (PVR) applications with two video decoders, hardware DMA and encryption. It also includes an output channel for connecting an LCD panel with high-definition multimedia interface (HDMI) transmitter.
