www. • September/October 2016 • SECURIT Y TECHNOLOGY E XECUTIVE 17 be urbanized. Dense populations put great stress on city services, leading to greater focus on technologies that improve operations, prevent loss, improve safety and security and are essentially "smarter." It is no accident that on November 15-17, Hous- ton, Texas will host the leading public safety secu- rity technology conference, Secured Cities (www. Houston is a city with nation- ally recognized medical, public safety and com- merce leadership, together with the ability to keep pace with the United States' second highest growth rate of 6.7 percent from 2010-2014. It has one of the most sophisticated Emergency Operations Centers and efficient Next Generation 911 Centers in North America. Finally, a successful datacasting pilot pro- gram has given first responders and city manage- ment an innovative alternative infrastructure for communications and video surveillance. The Internet of Things concept clearly emphasiz- es mobile devices, connectivity, video surveillance, wearables and actionable data solutions as the tech- nology trendsetters for 2016. But how do we identify and differentiate technology's often cyclic hype and long-term acceptance? A " hype" cycle [ ii] is a graphical representation of the stages a technology goes through from con- ception, marketability, expectations management, maturity and finally, widespread adoption. Initially a "Technology Trigger" may lead to "Inflated Expec- tations," an adjustment, followed by gradual, sus- tained market acceptance, or the technology "prom- ised land" (See Table 1 , "The Hype Cycle: A Technology Assessment Tool") Some technology, like video analytics, even with the great sophistication of solution providers and great benefits already realized by the security and public safety industries, in past years and some mar- kets had been "stuck" in a valley of lower acceptance, but is now in a gradual, sustained growth phase (see Hype Cycle – Data Sciences). Others, like autonomous vehicles, may be in for a gradual evolution and shake-out, whereas field autonomous vehicles in supply transport, warfare, and planetary excursions are more widely accepted (see Table 2 "Hype Cycle, Emerging Technologies). Autonomous vehicles benefit from powerful embed- ded systems with GPU (graphic processing units), 4K/ UHD camera systems, advanced video analytics and geospatial intelligence, all of which are making a greater impact on the security industry. 4K and UHD 4K and Ultra High Definition (UHD) video content has approximately four times the resolution (4 times the number of actual pixels) of 1080p full HD. 1080p content has more than twice than 720p resolution. Add audio, metadata, potential multiple camera streams and you are really referring to data-rich Digital Multimedia Content (DMC). You will also be looking seriously at methods of limiting bitrate, calculating and reducing the storage footprint and the ability to find objects of significance, especially where this content is actually being used as Digital Multimedia Evidence (DME). Include the ability to search through metadata, and you are more likely to be comfortable with large amounts of unstructured video data. A "next generation" codec includes an encoder that offers efficient, real-time compression of video, audio and metadata for more efficient streaming , decod- ing, and storage, ultimately taking up less disk space. The decoder extracts the audio or video information from the compressed video stream in real time or for forensic review purposes. Next-generation video codecs, when applied to 4K/ UHD, 1080p Full HD or 720pHD content can result in three areas of efficiency: (See Table 3) • From 46 – 73 percent reduction in bitrate or reduced storage over HEVC, depending on use case (The results are presented in the table "Com- parison of HEVC bit rate savings over AVC and Zipstream bit rate savings over AVC" [iii] ) • Increase the number of cameras as allowed by the bitrate or storage savings • Increase frame rate or image quality as allowed by the bitrate or storage savings Next generation codecs make it possible to deliver mission-critical video streaming at reduced bitrates. These efficient video compression technologies make it possible to use higher resolution and increase forensic detail while reducing storage cost and Table 1
