Abstract
A video data scaling arrangement as implemented with both vertical and horizontal scaling provided using the same programmable filter. The scaling is provided as rows of video data are received from a video source. According to one example embodiment using an incoming video data stream, video data is received sequentially according to a schedule of portions characterized by one of the dimensions of the sequence and, for each sequence of elements of the video data stream within a first video field of at least a two-field video frame, the sequence of elements of the video data stream is received in a first dimension, and the sequence of elements of the video data stream is filtered in the first dimension using a programmable scaling filter to provide a first set of scaled data having a first scaled dimension and having at least a second dimension. During a subsequent field time of the video and for each sequence of the first set of scaled data in a second dimension, the first set of scaled data is filtered using the programmable scaling filter to provide a set of two-dimensionally scaled data having at least two dimensions. Advantages include little, if any, support and overhead from a data processor.
