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.
