bandwidth consumption. Our new codec PERSEUS exemplifies this shift. The technology is built around the current generation of processors on a newer set of mathematical transforms designed for the visual characteristics of 4k and beyond, all the while running on existing off-the- shelf hardware to reduce costs. Critically, PERSEUS is also designed to work over today’s infrastructure and workflows and even enable operators to use PERSEUS in combination with legacy MPEG codecs. The issue of squeezing increasingly high bandwidth video down small pipes is even more pressing for the burgeoning mobile video market. Delivering HD content over crowded 3G and fledgling 4G networks is an initial challenge that the new era of compression technologies need to solve. In a recent trial using PERSEUS, British telecom giant EE streamed 4k quality video live over its 4G network without disruption, whether in central London at rush hour, or in rural areas such the New Forest. This demonstrates that compression technology can help operators deliver any type of content to any device over any network seamlessly and without interruption. The new compression technologies such as PERSEUS also solve the bandwidth issue by reducing the number of streams needed to serve audiences with different quality requirements. By virtue of its hierarchical format, PERSEUS is natively multi-scale, meaning that all levels of quality for any given content may be contained in a single file or stream. For example, content may be distributed to set-top-boxes (STB) in 10Mpbs UHD while the stream can then be “stripped off” and viewed on mobile device quality at SD rates as low as 0.125 Mbps. This combination of advanced compression and multi-scale delivery offers the potential to improve the bandwidth demands in future applications such as immersive TV, glasses-less 3D, High Dynamic Range broadcast and the relentless rise of video gaming. Compression technology will play a crucial part in solving the 4k conundrum, and utilising new codecs that address the business, bandwidth, picture quality and workflow challenges will enable operators to offer better content across a larger range of devices to any type of consumer.
