| Artificial intelligence is poised to disrupt content delivery. An open question is how to make AI work in conjunction with existing (and upcoming) video coding and transport standards. iSIZE is the first company to deliver deep neural networks for data-driven video preprocessing in order to provide significant bitrate savings over any standardencoder, or significant quality improvement at the same bitrate. In recent commercial trials, we have already showcased over 50% reduction in bitrate (or commensurate gains in visual quality) against advanced implementations of all video coding standards, without any change on the consumer side. However, this is only the beginning: as deep learning capabilities begin to penetrate consumer devices, iSIZE’s AI ecosystem is poised to improve further over time due its data-driven learning. This will also allow for other advanced AI services like automated tagging and recognition to run seamlessly in conjunction with live content delivery. | $912.5K / Seed / May 11, 2020 | ||
