General Description
Digital video up/down scaler permits independent horizontal and vertical scaling to generate any desired resolution or aspect ratio. Uses a 5x5 FIR polyphase filter with 16 phases to generate a studio-quality output. No frame buffer or external memory required.
Key Design Features
- RGB or YCbCr video in/out
- Independent vertical and horizontal scaling
- Support for different RGB channel widths
- Best suited to video resolutions up to full HD (1920x1080)
- Real-time programmable scaling parameters
- 5x5-tap polyphase FIR filter (16 phases)
- Fully pipelined architecture with simple flow-control
- ABMA / AXI4-stream compatible interfaces
- No frame buffer or external memory required
- Small area footprint - minimal RAM resource
- Support for 350MHz+ operation on basic FPGA devices
Applications
- Studio quality video scaling
- Video conferencing
- CCTV applications
- Broadcast video equipment
- Picture-in-picture (PiP), Picture-by-picture (PbP) and digital zoom
- Video scaling for flat panel displays, image sensors and cameras,
portable devices, video games/consoles, video format converters,
set-top boxes, smart TVs etc.
