The Progressive PNG Development Project
The goal of this project is to develop and commercialize a new way to send PNG images with multiple, high quality and progressively higher resolution images in a total file size less than that of the highest resolution image by itself, supporting both a form of responsive image delivery as well as a faster and higher quality presentation of images compared to the interlaced approach.
Where did this project come from? The basic algorithms for this project are based on Multi-Format Encoding (MFE) – a patented process originally developed to encode UltraWide moves onto Blu-ray discs with both standard and higher, anamorphic resolutions. It then seemed natural to cross develop the technology for internet images. The MFE process involves the use of extra data to add resolution to a given image. These extra data files are actually a type of image themselves that work best in a near-lossless file format so PNG was chosen as the platform.
Where is this project going? This technology will be commercialized as either an SaaS (Software as a Service) or licensed WordPress plugin or some combination thereof to make it easy to convert images to the progressive PNG format for distribution over websites (and wherever else it can be used). Whether this is something HifiPix launches itself or in partnership with someone else is TBD.
Yes, it works: Below are actual images using the progressive PNG process. The images are scaled down in the browser to fit on the page but can be clicked for full size. Even though the process offers images in multiple resolutions, the total file size of all images is less than just sending the highest resolution image by itself.
