Abstract:
1. A buffering system for facilitating the processing of pixels in a horizontal format converter, the system comprising: a FIFO buffer for buffering an input pixel line including a plurality of pixels, the FIFO buffer also including a plurality of FIFO buffers in parallel and wherein the plurality of pixels are buffered in the plurality of parallel FIFO buffers in an alternating fashion; a filter for processing pixels read from the FIFO buffer to generate an output pixel line; and a controller for adapting the reading of pixels from the FIFO buffer to the filter such that a variable sequence of pixels may be read from the FIFO buffer to the filter in accordance with an expansion mode, a compression mode, and a pass through mode, wherein the controller, in accordance with the compression mode, adapts the reading of pixels from the plurality of parallel FIFO buffers such that selected pixels are read from selected FIFO buffers of the plurality of FIFO buffers to the filter.
