Architecture overview
The PRISTINE board is composed of the following elements:
- One JPEG 2000 Encoder/Decoder.
- One PCI-Express (8 lanes) access.
- One De-Embedder / Embedder managing audio, timecode, metadata .
- One Serializer/ Deserializer handling parallel independent picture streams (e.g. 2 HD channels at 60 frames per second) or frame quadrants (e.g. for 4K or QuadHD images).
Performance
The PRISTINE P2 model is the second performant card amongst the PRISTINE familly. The performance are detailed according to :
Encoding quality
-
Visually Lossless : Visual quality is constant over the stream such that no artifact is visually noticeable. This typically corresponds to a compression ratio of 8:1 (i.e. 250 Mb/s for 2K content 4:4:4 12bpp). The overall bit rate is variable (VBR – Variable Bit Rate). The 9/7 wavelet filter is used for the JPEG 2000 compression.
-
Capped Variable Bit rate: Constant quality is applied, but the variable bit rate is capped at a given maximum limit. The 9/7 wavelet filter is used for the JPEG 2000 compression.
-
Nearly Mathematically Lossless (NMLS): The 5/3 reversible wavelet transform is used and a maximum bit rate applied. This results in a mathematically lossless compression for most frames, except for a few for which the rate will be capped. Typical compression ratio is 3:1 to 5:1. The overall bit rate is also variable (VBR).
-
True Mathematically Lossless: The 5/3 reversible wavelet transform is applied without any maximum bit rate to provide bit-to-bit lossless compression of all frames. Typical compression ratio for natural images is 2:1 (4:1 for synthesis images).
Input/Output access:
- SDI Video link: 3G-SDI, HD-SDI, SD-SDI.
- PCIe Data File: PCI-Express (8 Lanes) file-based access. The performance level is expressed in frames per second for the highest resolution specified for each board version, whatever the nature of the content. Depending on the application, lower frame rates can be supported. In the specification tables, average frame rate is an indicative fps for usual content.

3G-SDI panel
The size of the panel is half-width and half-height of a 19 inches Rack Unit. 4 different panels can thus be placed in a single RU. Pannels are connected to the PRISTINE through 1m long Infiniband cable. The panel has 4inputs / 4 outputs , all 3G-SDI also supporting HD-SDI and SDI. No additional power supply is required for this panel.
IP Streaming Library (RTP)
intoPIX proposes an efficient software library and some reference codes for real-time streaming of JPEG2000 codestream and audio data over internet. It supports high image quality and resolution up to HD, HD3D and 4K
