Classification: CPC H | IPC H

Claim 11:
12. 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 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
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.
