The VSC-4KX is a high quality polyphase scaler for up/down/cross conversion between video formats up to 4K resolution. The VSC-4KX up converts SD/HD video signals to 4K resolution and down converts 4K inputs to SD or HD. In addition, the VSC-4KX can cross convert a 4K input to a 4K output with up/down scaling. Quadrant based format as used with Quad 3G-SDI links is supported.
