Decoding video data. At least one video stream including a first plurality of frames encoded at a first resolution and a second plurality of frames encoded at a second resolution are received, wherein the second plurality of frames encoded at the second resolution directly correspond to at least a subset of the first plurality of frames encoded at the first resolution, and wherein the first resolution is greater than the second resolution. The video stream is decoded based on at least one received frame of the first plurality of frames encoded at the first resolution and at least one received frame of the second plurality of frames encoded at the second resolution.
