Abstract
A block of video data can be encoded using intra prediction followed by transforming the generated residual block where the transform size is different from the prediction size. A plurality of transform modes for the residual block is provided whereby the transform subblocks of the residual block are transformed using horizontal and vertical one-dimensional transform types. The transform types may be selected such that their base function corresponds to a pattern in the data of the generated residual block resulting from the intra prediction mode. As a result, the position of each block relative to the peripheral pixels used to generate a prediction block for the block may be used to select the transform types.
