Claim 20:
21. A device for requesting a reduced resolution for video data, the device comprising:
a memory configured to store video data; and
a processing system comprising one or more processors implemented in circuitry, the processing system being configured to:
decode a first sequence of pictures of video data of a bitstream, the first sequence of pictures having a first spatial resolution;
in response to determining that the device is to enter a power saving mode:
form 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 processing system is configured to form the message as a region encoding message including a top offset field specifying a requested offset for a top of the pictures of the second sequence of pictures relative to a top of the pictures of the first sequence of pictures, a bottom offset field specifying a requested offset for a bottom of the pictures of the second sequence of pictures relative to a bottom of the pictures of the first sequence of pictures, a left offset field specifying a requested offset for a left side of the pictures of the second sequence of pictures relative to a left side of the pictures of the first sequence of pictures, and a right offset field specifying a requested offset for a right side of the pictures of the second sequence of pictures relative to a right side of the pictures of the first sequence of pictures; and
send the message requesting the second, reduced spatial resolution relative to the first spatial resolution for the second sequence of pictures; and

decode the second sequence of pictures of the video data of the bitstream, the second sequence of pictures having the second, reduced spatial resolution.
