Claim 0:
1. 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 video data of a bitstream, the first sequence of pictures having a first spatial resolution;
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 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; and
sending, by the client device, the message requesting the second, reduced spatial resolution relative to the first 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.
