Abstract:
1. A system for scaling and filtering video images, the system comprising: a scan converter for converting video data into pixel data, the scan converter having an input and an output, the input coupled to receive a video signal; a memory for storing scaling and filtering coefficients, and a scaling and filtering module having inputs and an output for scaling and filtering the video signal using scaling and filtering coefficients, a first input of the scaling and filtering module coupled to the output of the scan converter, and a second input of the scaling and filtering module coupled to the memory for retrieving the scaling and filtering coefficients, wherein the scaling and filtering module performs horizontal upscaling scaling and filtering concurrently, and wherein the system further comprises a second scaling module for performing horizontal downscaling, the second scaling module having an input and an output, the input of the second scaling module coupled to the output of the scaling and filtering module, and a third scaling and filtering module having inputs and an output for performing vertical scaling and filtering concurrently, a first input of the third scaling and filtering module coupled to the output of the second scaling module, a second input of the third scaling and filtering module coupled to the memory to retrieve coefficients.
