1. A method comprising:
- receiving, at a media device, a video stream request to initiate a channel change operation, the video stream request indicating a requested video stream, and the requested video stream comprising a sequence of frames; and
in response to the video stream request;
receiving a first subset of frames of the sequence of frames;
generating a first low resolution video stream comprising a first sequence of first low resolution frames by processing the first subset of frames of the sequence of frames;
after receiving the first subset of frames, receiving a second subset of frames of the sequence of frames, wherein the second subset of frames is subsequent to the first subset of frames in the sequence of frames;
generating a second low resolution video stream comprising a second sequence of second low resolution frames by processing the second subset of frames of the sequence of frames;
after receiving the second subset of frames, receiving a third subset of frames of the sequence of frames, wherein the third subset of frames is subsequent to the second subset of frames in the sequence of frames;
generating a full resolution video stream comprising a third sequence of full resolution video frames by processing the third subset of frames of the sequence of frames;
during a first time period, sending the first low resolution video stream to a display device;
during a second time period after the first time period, sending the second low resolution video stream to the display device;
synchronizing the second low resolution video stream with the full resolution video stream; and
during a third time period after the second time period, sending the full resolution video stream to the display device, wherein a first resolution of the first low resolution video stream is lower than a second resolution of the second low resolution video stream, and wherein the second resolution is lower than a third resolution of the full resolution video stream.

Abstract
A particular method includes receiving a video stream to be displayed on a display device. The method also includes, during a first time period, sending a low resolution version of the video stream to the display device while recovering a full resolution version of the video stream. The method further includes synchronizing the low resolution version of the video stream with the full resolution version of the video stream. The method also includes, during a second time period after the first time period, switching from sending the low resolution version of the video stream to the display device to sending the full resolution version of the video stream to the display device.
