Claim 22:
23. A device for requesting a reduced resolution for video data, the device comprising:
means for decoding a first sequence of pictures of video data of a bitstream, the first sequence of pictures having a first spatial resolution;
means for forming, in response to determining that the device is to enter a power saving mode, a message specifying a second, reduced spatial resolution relative to the first spatial resolution for a second sequence of pictures, the second sequence of pictures being subsequent to the first sequence of pictures in coding order, wherein the means for forming the message comprises means for forming the message to include a picture width field specifying a requested width of the second, reduced spatial resolution for the pictures of the second sequence of pictures picture and a picture height field specifying a requested height of the second, reduced spatial resolution for the pictures of the second sequence of pictures, the second sequence of pictures being subsequent to the first sequence of pictures in coding order;
means for sending the message requesting the second, reduced spatial resolution relative to the first resolution for the second sequence of pictures; and
means for decoding the second sequence of pictures of the video data of the bitstream, the second sequence of pictures having the second, reduced spatial resolution.
