This buffer, containing a DDR-SDRAM external memory, always keeps at least one valid frame that can be repeated when convenient. The quantization steps are defined in the main header of the JPEG 2000 file and can be different for each subband.Ī frame memory buffer is used at the Inverse Quantizer output and enables an efficient IDWT processing. The coefficients of the wavelet subbands are inverse quantized. With this information, the Arithmetic Decoder decodes the bit-stream. The Context Modeller successively decodes each bit-plane of the codeblock by sending information describing the neighbourhood of each bit to the Arithmetic Decoder. The reconstruction of each wavelet sub-band divided into several code-blocks is achieved by two blocks: the Context Modeller and the Arithmetic Decoder. The JPEG 2000 parser analyses the main and tile-part headers of the JPEG 2000 codestream and sends the compressed bit-stream to the entropy decoder. ![]() External memory * : support DDR3, DDR2, LPDDR2, DDR4.Fully customizable IP-core per application, delivered and silicon proven with intoPIX HDK for fast integration.FPGA: support the latest AMD-Xilinx & Intel series and previous series.Auto-downscaling and auto-upscaling capability from HD/2K to UHD/4K.Optional automatic frame repeater or interlacer.On-the-fly codestream integrity check and error robustness.Configuration control: through control bus or through codestream control packets.Up to 16 preloaded channel configurations.Real-time access to status registers for monitoring and debug.Configuration control: through control bus or through video interface.Up to 64 preloaded configurations and frame per frame control.down to 5 milliseconds with end-to-end compression in 1080p60 or 2160p60) Latency goes down to 2/16th of a frame (field) at encoding and to 1/16th of a frame(field) at decoding with IPX-QO (quality optimizer) (ie. ![]() Ultra-low latency (Sub-I-frame): This unique solution comes with the optional quality optimizer mode (IPX-QO) that adds an incredible robustness.Low latency: configurable from 1 to 2 frames (fields) at encoding from 0,5 to 1 frame(field) at decoding (ie.True Mathematically Lossless (MLS): 5/3 wavelet reversible transform - no max bit rate - bit to bit lossless compression - 2:1 to 3:1 compression.Nearly Mathematically Lossless (NMLS): 5/3 wavelet reversible transform with an applied maximum bit rate - 3:1 to 5:1 compression. ![]()
