Sending Mobile Display Signals to a TV Screen

NXP Semiconductors has launched a mobile TV-out processor to enable TV-output on any mobile phone having a standard LCD screen. The NXP SAA8510 converts mobile digital video signals into high-quality analog TV signals, which can then be displayed on any NTSC and PAL TV set.

Apart from domestic applications, the service would also be of considerable use to demonstrators seeking to show mobile content services on a larger display for an audience.

"As the cell phone continues to become known as the worldĂ's 'third screenĂ' behind the TV and PC, consumers will need the added flexibility to access their mobile content beyond the two inch screens of most mobile devices," said Vincent Pronk, Multimedia Marketing Manager, Business Unit Mobile & Personal, NXP Semiconductors. "We developed the SAA8510 TV-out processor in close collaboration with our key customers to help fuel the convergence of mobile and home multimedia, and to give end-users the freedom to take their mobile content from the small screen to the big screen whenever they want."

Although mobile picture quality is still generally low resolution, NXPĂ's TV-out processor enables mobile images to be displayed on larger TV screens. The output is enabled by a polyphase up/down scaler that allows different scale factors horizontally and vertically. Chrominance and luminance filters limit dot crawl effects and tearing effects are managed using a dedicated tearing effect signal.

Supported input formats are RGB888, RGB666, RGB565, YUV422 and YUV420 for resolutions from 40x40 pixels to VGA (including WQVGA).

The NXP SAA8510 TV-out processor is available now from NXP.
