Digital Picture Frame (DPF)

Digital Picture Frame (DPF) Solutions from Texas Instruments

Description

The Digital Picture Frame (DPF) solves the problem of displaying digital photos (optional also music and videos) without a computer. While the basic function models can just show JPEG pictures in a slide show, multimedia features (zoom and rotate pictures, play music and videos, support of all popular memory cards, internal memory, auto on/off, etc.) require high-end components but staying on the low-end side on power consumption. Next generation multimedia picture frames offer the possibility to connect to the Internet and download pictures or information (weather, news, …) from a server.

The core subsystem includes:

  • Video Engine and Microprocessor – perform the processing of JPEGs and decoding of MPEGs, handle audio processing, and control the power management and user interface. While many functions can be integrated there might be a need for discrete solutions on the audio, video and interface side.
  • Audio – provides audio output for up to two channels usually decoded by the processor. So digital to analog conversion and amplification is needed.
  • Memory – stores executing code, data/parameters, and pictures, movies and sound. Switching and voltage level translation might be required for memory cards.
  • User Interface – allows the user to control the digital picture frame using buttons, remote or touch screen control.
  • Power Conversion – converts the input power from the AC/DC wall adaptor to run various functional blocks. Battery charge management can be controlled by the microprocessor.
