Wireless Digital Picture Frame

Falling LCD prices, rising computing power in dedicated chips, and the arrival of Wi-Fi and Bluetooth connectivity have contributed to the increasing popularity of the wireless digital picture frame (DPF). What originally began as an adaptation to the laptop screen has evolved into an independent device that brings news, weather, traffic updates, and shared video and photographs to the home. Often equipped with a clock, alarm, calendar and scheduler, the wireless DPF has clearly become a multi-functional device with real value.

The XpandR^® II chipset is DSP Group^®'s new-generation wireless multimedia processor. Providing at-home wireless connectivity with multimedia capabilities, the XpandR II enables the development of the wireless DPF through several components:

• Application processor - DMW74 (DW74)
• Power management unit and analog front end - DP
• Wi-Fi RF - RF52
• DECT RF - RF19 (optional)

The next-generation Wi-Fi digital picture frame maintains a workflow featuring a fully functional Internet-based content provisioning service. As a result, the wireless DPF provides back-end web-based services that automatically "update" each frame with pictures and other digital content such as weather forecasts and RSS feeds.

While consumers until now have had to use a media player serving as a DLNA client, along with USB Wi-Fi dongles, to update data, life is now far simpler with the wireless DPF. Connecting to access points that use open networks and WEP/WPA encrypted networks that utilize a WPS mechanism for a fast and easy connection, the stand-alone wireless DPF enables users to receive and share photographs and content without a PC.

Designed in a stylish, mobile form factor, the wireless DPF is a user-friendly device with touch-screen support capabilities that enable easy navigation and selection of photo albums and a host of other content.

DSP Group has combined its XpandR HDK development platform and XpandR chipset family to offer a unique all-in-one, single-code enabler that supports DECT and Wi-Fi. Ideally suited for PC-free multimedia web devices such as wireless DPFs, infotainment centers and Internet radios, the XpandR family utilizes the open Linux code for seamless software portability and application availability. As a result, customers can select their preferred application layer package when developing devices like the wireless DPF.

By bringing together the best of Wi-Fi/DECT and audio/voice on one chip, DSP Group offers a cost-efficient solution that cannot be matched by non-integrated offerings.
