4K display and compression technologies from i-Chips and intoPIX available from L2Tek

The intoPIX Ultra HD JPEG2000 encoder & decoder FPGA IP-cores offer ultra-low latency signal transmission and lossless video compression. The i-Chips quad-scalar, the IP00C732, is a complementary flexible display processor that supports a 4096 pixels/line (4K) raster across 1 to 4 screens for Ultra High Definition Television (UHDTV).

The IP00C732 is an easy-to-programme alternative to FPGAs for high-resolution displays. It can also be configured to drive a single 1080P or WUXGA output with 4 input images tiled together on a single output. The device has 4 input channels at 166 Mpixels/second each in RGB, YUV4:2:2 or YUV4:4:4 formats. It features 4 independent scaler blocks, with full 10-bit internal processing. The device has an output overlay block that is fully programmable to suit different applications. The block can be programmed to superimpose all 4 inputs in any combination with alpha blending or colour key blending. When used on a single high-resolution display, the device has an image overlap feature to produce a seamless image without any artifacts.

intoPIX encoder and decoder cores run on Altera or Xilinx FPGAs. The JPEG2000 compression standard was chosen as it delivers greater compression capability, scalability, flexibility and visual quality while being an open standard supporting every resolution, colour depth, number of components and frame rates. The 4K and preliminary announced 8K cores have an optimised FPGA footprint, reach 60 frames per second and offer great flexibility in the codestream bitrate control. This enables visually or mathematically lossless compression. Maximum bit depth is 12 Bits per component. Low latency – less than one frame – and chrominance sub-sampling of 4:4:4 or 4:2:2, make these cores suitable for digital cinema and emerging UHDTV applications.
