The UHT-SCALER core provides a video processing block which converts input video frames of one size and sampling format to output frames of a different size and/or sampling format. It supports scaling of 4:4:4, 4:2:2, 4:2:0 and 4:0:0 (grayscale) video streams with 8- up to 16-bit color depth, using the BILINEAR, BICUBIC, LANCZOS and EXPFILTER scaling methods. High quality de-Bayer support is also included. The UHT-SCALER is a standalone and high-performance image and video scaler core, designed for enabling high-quality and ultra-high throughput performance, even in low-end target silicon technologies. The UHT-SCALER is available for Altera FPGA and SoC based designs.

The core accepts the input image data in planar or interleaved scan order format and outputs the scaled image data in the same planar or interleaved format as the input. The UHT-SCALER is very easy to use and integrate in a system. It requires minimal host intervention as it only needs to be programmed once per video sequence. Once programmed, it can scale an arbitrary number of video frames without the need of any further intervention or assistance by the host system CPU.
