白皮书: Extron 多网口控制处理器
Multi-network control processors enable AV system designers to balance the need for access to network resources and network security. The control processor with AV LAN ports sits between devices like video codecs and presentation computers on the corporate LAN and isolates AV devices on the segregated and secure AV LAN that do not require network resources, such as a touchpanel. This whitepaper discusses networking strategies for AV control systems and provides strategies to deploying control processors with AV LAN ports using Global Configurator Plus and Professional, Global Scripter, and Toolbelt.

白皮书: 高动态范围视频剖析
Over the past seven decades, display technology has progressed to the point where 4K/Ultra HD video is now the gold standard. 4K resolution yields four times the number of pixels as HD video, but depending upon the size of the display and the viewing distance, there may be no perceptible difference between an HD image and a 4K/UHD image. Adding HDR - High Dynamic Range to a 4K/UHD image is the differentiator that takes 4K/UHD far beyond what HD can offer. HDR enhances the quality, rather than the quantity, of the pixels being displayed since it provides richer colors and greater contrast.

EDID:识别并解决常见问题的指南
HDMI, DVI, and DisplayPort require successful two-way EDID exchange between a display and a source to establish a connection between them. This in turn enables the flow of digital AV content from the source to the display. Problems with EDID communication are major causes of failure in digital video systems, with no image display as the typical symptom. This paper will provide a clear explanation of EDID, and identify EDID-related issues commonly encountered in the field, with suggested guidelines for successfully resolving them. With a better understanding of these issues, effective EDID strategies can be applied toward future system designs to ensure reliable and consistent system operation.

数字视频信号入门知识
Digital video signals are becoming widely prevalent throughout the AV industry. They are considerably different in comparison to traditional analog video signals, with specific performance and timing requirements that must be maintained throughout the entire signal path. This paper offers an introduction to digital video signals and the digital video formats currently in use. It also explains how eye diagrams can be used to quantify and visualize digital video signal integrity, and the importance of digital video signal conditioning when designing digital AV systems.
