Representative Sample Support

Windows Media Player 11 introduces support for transferring representative samples ("thumbnails") of images and videos to devices. A representative sample will consist of a scaled-down image to represent an image or video.

To receive these samples, devices should declare support for the following object properties for the EXIF format if image samples are requested and for the WMV format if video samples are requested in the GetObjectPropDesc:

RepresentativeSampleWidth - Set to GET/SET, with a none-zero value

RepresentativeSampleHeight - Set to GET/SET, with a none-zero value

RepresentativeSampleData - Set to GET/SET

RepresentativeSampleFormat - Set to GET/SET, Supported formats must include EXIF

The RepresentativeSampleWidth and RepresentativeSampleHeight will be used to determine what size the device prefers the representative data image.

Windows Media Player 11 will send a JPG using the RepresentativeSampleData property.

For interdependent format properties, only the first interdependent property for each of EXIF and WMV formats will be queried for the above properties.

Please refer to the MTP Specification for details on each of the object properties.
