A video signal can be decoded at a reduced resolution by receiving a video signal encoded at a first resolution; determining a second resolution at which the received video signal is to be decoded, wherein the second resolution is lower than the first resolution; and decoding the received video signal at the second resolution. The second resolution can be selected from a plurality of predetermined decoding resolutions. Further, the second resolution can be selected in response to an input received from a user. Decoding of the received video signal can include scaling one or more reference pictures by a first scaling factor and scaling one or more non-reference pictures by a second scaling factor. Additionally, scaling can comprise transforming a first portion of frequency coefficients associated with a block of picture information and discarding a second portion of frequency coefficients associated with the block of picture information.
