Patent ID: 8385427

Claim:
A method, comprising: playing, by a media player, a portion of a video signal at a first display resolution, the video signal decoded from received data coded at a coding resolution; when the display resolution changes to a second value: decoding, by a decoder associated with the media player, one or more non-reference pictures associated with a subsequent portion of the video signal at the second display resolution, wherein the decoding includes motion-based prediction, including scaling motion vectors in a horizontal direction and a vertical direction using a horizontal scaling factor that is different from a vertical scaling factor; and decoding one or more reference pictures associated with the subsequent portion of the video signal at a decoding resolution that is smaller than the coding resolution and higher than the second display resolution; and playing, by the media player, the subsequent portion of the video signal at the second display resolution at least in part by adjusting the one or more decoded reference pictures decoded at the decoding resolution to discard one or more elements of picture information, each element of picture information being represented in a spatial domain, such that the adjusted one or more reference pictures are to be displayed at the second display resolution, and displaying the adjusted one or more reference pictures and the decoded one or more non-reference pictures at the second display resolution.
