present the first video stream for display;

in response to receiving a first command, change to decode the second video stream from the first rate to a second rate based at least in part on a determination determined using the first level of the video characteristic and the second level of the video characteristic, wherein the second rate is different from the first rate, and wherein the second level of the video characteristic is different from the first level of the video characteristic; and

present the second video stream directed to the same video content as the first video stream for display while stopping displaying the first video stream.

9. The system of claim 8 , wherein the determination comprises the one or more processors, the one or more circuits, or any combination thereof configured to:

determine that decoding the first video stream requires more decoder power than decoding the second video stream using a comparison between the first level of the video characteristic and the second level of the video characteristic.

10. The system of claim 8 , further comprising the one or more processors, the one or more circuits, or any combination thereof configured to:

in response to receiving the first command, change to decode the second video stream from the first rate to the second rate while stopping decoding the first video stream.

11. The system of claim 8 , wherein the first video stream is decoded using a first decoder and the second video stream is decoded using a second decoder.

12. The system of claim 8 , further comprising the one or more processors, the one or more circuits, or any combination thereof configured to:

receive a second command;

in response to receiving the second command, change to decode the second video stream from the second rate to the first rate and determine whether the first video stream is at a transition point;

in response to determining that the first video stream is at the transition point, present the first video stream for display while stopping presenting the second video stream for display; and

in response to determining that the first video stream is not at the transition point, present the second video stream for display until the first video stream is at the transition point, and in response to the first video stream at the transition point, present the first video stream for display while stopping presenting the second video stream for display.

13. The system of claim 10 , further comprising the one or more processors, the one or more circuits, or any combination thereof configured to:

receive a second command;

in response to receiving the second command, change to decode the second video stream from the second rate to the first rate and determine whether the first video stream is at a transition point;

in response to determining that the first video stream is at the transition point, start to decode the first video stream; and

in response to determining that the first video stream is not at the transition point, wait until the first video stream is at the transition point to decode the first video stream.

14. The system of claim 8 ,

wherein the video characteristic comprises at least one of a resolution, a frame rate, a bit precision, a bit rate, or a chroma subsampling, and

wherein the first command comprises a trick mode command, the trick mode command including at least one of a fast forward command or a rewind command.
