Gary Kayye’s annual Krystal Ball series, which comes out each January, is likely the most-read news article in AV every year. Why? Well, he’s usually right — like 90 percent of the time. For example, he predicted the impact that Bluetooth would have on the ProAV market even when others were calling it just a consumer standard — he did the same with Dante. He correctly identified that HDMI would become the standard in signal routing three years before anyone else was talking about it. He did the same with 4K. And, OLED and 3LCD vs. DLP. Oh, and HDBaseT. So, if you want to know what he thinks of AV-over-IP, the new rollable OLEDs, the collaboration board market, the future of meetings rooms and what’s likely to happen with the control system market in 2019, then you need to attend this class! Gary will walk you through his 2019 predications, the latest AV trends and what to watch for throughout the year. Presented by Gary Kayye © THE rAVe Agency

The success of a converged AV/IT system is dependent on a properly installed and tested structured cabling system. As more and more audiovisual integrators are offering IT infrastructure installation to their clients, it is mandatory that they have an understanding of the hardware and test procedures required. This seminar explores the hardware and installation equipment necessary to install and terminate UTP cabling, including punch blocks on patchbays and wallplates, and RJ-45 connectors on cabling. Structured cable installation issues such as cable pathways, signal interference, and distance limitations are covered. Finally, test parameters and equipment including cabling verification testing and network certification testing are demonstrated. Presented by Tom Kehr © AVIXA

Nearly everyone out there is misleading you about AV-over-IP. It’s not easy, it’s not lossless compression and it’s not going to happen overnight. But, it IS the future of AV signal distribution. There is no standard that everyone has adopted for sending AV signals (video, audio, control and power) over the network – there are multiple ways of doing it and none of the different options are interoperable. So, buyer and adopter beware. Gary Kayye’s latest keynote will help guide the future of AV-Over-IP as not only is he a respected AV technologist, but he’s help set the standards in signal routing before. So, both the manufacturers and the integrators will be listening to his opinions on this and which AV-Over-IP “standard” he likes best. Presented by Gary Kayye © THE rAVe Agency

The presentation explores the development and application of artificial intelligence (AI) from its inception to its current status in the modern world. The term "artificial intelligence" was first coined by John McCarthy in 1956 to describe efforts to develop computer programs capable of performing tasks that typically require human intelligence. This concept was first introduced at a conference held at Dartmouth College, where programs demonstrated capabilities such as playing chess, proving theorems, and interpreting texts. In the early stages, Alan Turing contributed to the field by defining intelligence as the ability of a being to respond to certain questions intelligently, proposing what is now known as the Turing Test to evaluate the presence of intelligent behavior in machines. As the decades progressed, AI evolved significantly. The 1980s focused on machine learning, teaching computers to learn from data, leading to the development of models that could improve their performance based on their experiences. The 1990s and 2000s saw further advances in algorithms and computational power, which allowed for more sophisticated data analysis techniques, including data mining. By the 2010s, the proliferation of big data and the refinement of deep learning techniques enabled AI to become mainstream. Notable milestones included the success of Google's AlphaGo and advancements in autonomous vehicles by companies like Tesla and Waymo. A major theme of the presentation is the application of generative AI, which has been used for tasks such as natural language text generation, translation, and question answering. Generative AI uses large datasets to train models that can then produce new, coherent pieces of text or other media. The presentation also discusses the ethical implications and the need for regulation in AI, highlighting issues such as privacy, bias, and the potential for misuse. These concerns have prompted calls for comprehensive regulations to ensure the safe and equitable use of AI technologies. Artificial intelligence has also played a significant role in healthcare, particularly highlighted during the COVID-19 pandemic, where it was used in drug discovery, vaccine development, and analyzing the spread of the virus. The capabilities of AI in healthcare are vast, ranging from medical diagnostics to personalized medicine, demonstrating the technology's potential to revolutionize fields beyond just technical or consumer applications. In conclusion, AI continues to be a rapidly evolving field with significant implications for various aspects of society. The development from theoretical concepts to real-world applications illustrates both the potential benefits and the challenges that come with integrating advanced technologies into everyday life. The ongoing discussion about AI ethics and regulation underscores the importance of managing these technologies responsibly to maximize their their benefits while minimizing potential harms.
