Claim 10:
11. A method of requesting a reduced resolution for video data, the method comprising:
decoding, by a video decoder of a client device, a first sequence of pictures of a bitstream, the first sequence of pictures having a first spatial resolution for the pictures in the first sequence of pictures;
in response to determining that the client device is to enter a power saving mode:
forming, by the client device, 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 forming the message comprises forming 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
sending, by the client device, the message requesting the second, reduced spatial resolution relative to the first spatial resolution for the second sequence of pictures; and

decoding, by the video decoder of the client device, the second sequence of pictures of the video data of the bitstream, the second sequence of pictures having the second, reduced spatial resolution.
